The purpose of this study is to examine the effect of combination of Andrographis paniculata herb fraction (AHF) and Centella asiatica herb fraction (CHF) on PPARγ and GLUT4 mRNA expressions
in 3T3-L1 adipocyte, and its effect on insulin-stimulated glucose uptake.3T3-L1 adipocyte cells were used to investigate gene expression of PPARγ and GLUT4 proteins by reverse transcription-polymerase chain reaction method. The adipocyte cells were differentiated by using insulin, dexamethasone and 3-isobutyl-1-methylxanthine from 3T3-L1 cells. Pioglitazone, AHF, CHF and the combination of both herbs were evaluated on glucose uptake activity, PPARγ and GLUT4 mRNA expressions in 3T3-L1 adipocyte. The results showed that combination of AHF at 30 μg/mL and CHF at 10 μg/mL could enhance insulin-stimulated glucose uptake. The combination also increased PPARγ and GLUT4 mRNA expressions significantly in comparison to those of negative control (DMSO). These effects were equal in comparison to those of pioglitazone (0.02 μM) and its single extracts.

The cost of administering modern anti diabetic drugs is usually beyond the reach of most people in
the low income group especially those in the developing world where the disease is on the increase. This has led
to the current shift to the use of preparations from various parts of plants because of the current increase in the
knowledge of their toxicity, side effects, active constituents and doses. This study was conducted to compare the
effects of the aqueous Carica papaya seed and leaf extracts on serum biochemistry of alloxan induced diabetic
rats especially glucose level. Male Wister rats weighing 150-200g were induced with single freshly prepared
alloxan monohydrate (150 mg/kg body weight).Diabetes was confirmed after seven days in alloxan-induced rats
showing fasting blood glucose levels ≥ 200mg/dl. The diabetic rats were randomly allocated into three
experimental groups which received Seed extract, leaf extract or normal saline depending on the group. The
extracts were administered orally for twenty-eight days after which the animals were sacrificed and blood
samples were collected for Biochemical analyses. The results showed that both extracts have significant
hypoglycaemic, hepatoprotective and nephroprotective effects although extract of the seed proved to be more
potent than that of the leaf

Effect of Ethanol leaf extract of Chromolaena odorata on lipid profile of str...PUBLISHERJOURNAL
Poor control of diabetes mellitus can result to impairment in lipid profile culminating to dyslipidemia, coronary artery disease and stroke. Measurement of triglyceride (TAG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) are recommended in cardiovascular screening. Herbal and natural products have been used in folk medicine for centuries throughout the world. The aim of this research was to determine the effect of ethanol leaf extract of Chromolaena odorata on lipid profile of streptozotocin-induced diabetic wistar albino rats. All the chemicals and reagents used in this research were of analytical grade. A total of 48 rats were randomly divided into 6 groups (n=8): diabetic rats in group 1 were not treated, rather received only 0.5ml normal saline; 0.5mg glibenclamide was given to diabetic rats in group 2; non-diabetic rats in group 3 received 0.5ml normal saline only, diabetic rats that were treated with 250 mg/kg, 350mg/kg and 450mg/kg b.w of ethanol leaf extract of Chromolaena odorata, were labeled groups 4, 5 and 6, respectively. At the end of the 21 days study period, the rats were fasted overnight and blood samples were collected via cardiac puncture. Lipid profile was assayed using standard biochemical methods. Injection of streptozotocin led to a significant (p<0.05) decline in HDL-C while the levels of TAG, TC, and LDL-C increased significantly. Remarkably, treatment with 250 mg/kg, 350mg/kg and 450mg/kg b.w of ethanol leaf extract of Chromolaena odorata led to reversal of the altered lipid profile. However, there were no significant differences (p>0.05) when the Chromolaena odorata extract-treated groups were compared to group 2 rats (treated with glibenclamide), a known standard antidiabetic drug. In conclusion, results from this research indicated that the ethanol leaf extract of Chromolaena odorata possess hypo-cholesterolaemic and hypo-triacylglycerolaemic effects as the extract decreased the LDL-cholesterol and increased the HDL-cholesterol levels.

ANTIDIABETIC POTENTIAL OF MEMECYLON TERMINALE DALZ EXTRACTS IN ALLOXAN INDUCE...Jing Zang
Memecylon terminale Dalz is an endemic plant that is exclusively present in the Western Ghat region of Southern India. The traditional healers in this region have been using this plant extract to cure disorders such as dysentery, diabetes, diarrhea, piles, haemoptysis, menorrhagia and shown to possess carminative stomachic astringent property. The present study was carried out to evaluate the hypoglycemic activity of different extracts of M. terminale Dalz in alloxan induced diabetic rats. Chloroform and methanolic extracts of M. terminale Dalz leaves were screened for hypoglycemic activity in alloxan induced diabetes in Swiss albino rats. The lipid profile was also examined in diabetic rats administered with these extracts. The efficacy of these extracts was also analyzed for their ability to inhibit α-glucosidase and α-amylase. Of the two extracts, chloroform extract (500 mg/kg body weight) showed dose dependent decrease in blood glucose level which was comparable to that of control after 24 h of extract administration. On the other hand, chloroform extract also showed good lipid profile that was comparable with standard drug. As compared to chloroform extract, the methanolic extract showed good inhibition of α-amylase and α-glucosidase enzyme activity. The results of our study indicate that M. terminale Dalz plant possesses significant protective effects against alloxan induced diabetes. However, detailed structure function analysis of active ingredients of the extract is needed to be validated.

Oral mucositis (OM) is a common inflammatory complication among cancerous patients as an adverse effect of chemotherapy and radiotherapy. The aim of this study is to evaluate the healing effects of hydroalcoholic extract of Psidium
Guajava leaf on oral induced mucositis induced by 5-fluorouracil using histopathologic and tissue antioxidative markers assessment in male dark brown rats. In a prospective randomized double blind animal study, OM was induced in 64 male dark brown rats that allocated in 4 groups by 5-FU (60 mg/kg) on days 0, 5, and 10 of the study. The cheek pouch was scratched with a sterile needle on once daily on days 3 and 4. Starting from day 12, gel base, topical form and 600 mg/kg dietry form of hydroalcoholic extract of Psidium Guajava leaf were administered per day. Pouch histopathology score, superoxide dismutase, glutathione peroxidase, total antioxidant capacity were evaluated on day 14 and 18. DPPH scavenging activity and total phenolic content also were measured. Histopathology scores of mucositis were lower in the systemic and topical treatment groups than the gel base and control groups (P<0.05). Higher activities of SOD, GPX and TAC were detected in the topical and systemic treatment groups in comparison to the others (P<0.05). The extract was rich in total phenolic content as antioxidant. The use of extract of Psidium Guajava leave may be associated with reduced intensity of OM, increased concentration of SOD, GPX and TAC on induced
OM in dark brown rats undergoing 5-FU consumption.

We conducted a national survey in 2015, and here we report the results concerning training characteristics during the surgical residence of the respondents. Materials and Methods: A prospective study was conducted through a survey questioning demographic data, laparoscopic training during pre and post surgical residency and other of areas of laparoscopic practice. The sample was calculated and survey piloted before
application. Special interest in this report was placed on type and quality of training received. Data are reported in percentages.
Heterotopic Ossification (HO) is defined as pathological bone formation at locations where bone normally does not exist. The
presence of HO has been found to be a rare complication after stroke in several studies, whereas there are only sporadic references relating HO to Cerebral Palsy (CP) and few for CP and stroke. No effective treatment for HO has yet been found, whereas the cellular and molecular mechanisms have not been completely understood. Therefore, increased awareness among physicians is required, as a challenge for early diagnosis and treatment. A case of a male patient with CP, who developed HO on the paretichip joint following an ischemic stroke is presented.

Information was gathered from interview and field observation by conducting food safety survey and using questionnaires via face to face interview. The collected data was entered using Epi Data 3.1 and finally, it was analyzed using SPSS VERSION 20.
A Division I football athlete experienced acute posterior leg pain while pushing off on the line of scrimmage. Ultrasound (US) showed a midsubstance plantaris tendon rupture, an injury that, to our knowledge, has only been described once before in the medical literature [1]. US was also used to assist with rehab progression and return to previous level of activity, which was achieved three weeks after the injury. While there currently are no guidelines regarding return to sport after this injury, this case demonstrates that once pain is controlled and ROM restored, progression through rehabilitation and return to elite level sport is simply based on symptoms.
Type 1 Diabetes (T1D), is a severe disease, representing 5-10% of all reported cases of diabetes worldwide. Fulminant Type 1 Diabetes Mellitus (FT1D) is a subtype of type 1 diabetes mellitus that is largely characterized by the abrupt onset of Diabetic Ketoacidosis (DKA) and severe hyperglycemia without insulin defi ciency. Viral infections have been hypothesized to play a major role in the pathogenesis of Fulminant Type 1 Diabetes Mellitus (FT1D) through the complete and rapid destruction of pancreatic beta cells. Coxsackie viral infection has been detected in islets of 50% of the pancreatic tissue recovered from recent-onset Type 1 Diabetes (T1D) patients. In this report we have highlighted a case where the patient developed a Group B Coxsackie virus infection culminating in the development of Fulminant Type 1 Diabetes Mellitus (FT1D).
Methods: Cercariae are released by infected water snails. To determine the occurrence of cercariae-emitting snails in SchleswigHolstein, 155 public bathing places were visited and searched for fresh water snails. Family and genus of the collected snails were determined and the snails were examined for the shedding of cercariae, using a standard method and a newly developed method.
Objective: To generate preliminary information about of enteroviruses and Enterovirus 71 (EV71) in patients with aseptic meningitis in Khartoum State, Sudan.
Method: Cerebrospinal fluid specimens were collected from 89 aseptic meningitis patients from different Khartoum Hospitals
(Mohammed Alamin Hamid Hospital, Soba Teaching Hospital, Omdurman Military Hospital, Alban Gadeed Teaching Hospital and Police Hospital) within February to May 2015. Among these 89 patients, 43 (48%) were males and 46 (52%) were females. The patient’s age ranged between 1 day and 30 years old. The collected specimens were assayed to detect enteroviruses and EV71 RNA using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) technique
Femoral hernias, comprise 2% to 4% of all hernias in the inguinal region, and occur most commonly in women. Th ey present typically with a mass below the level of the inguinal ligament. The sac may contain preperitoneal fat, omentum, small bowel, or other structures and have a high rate of incarceration and strangulation due to the small size of the hernia neck orifice, requiring emergency surgery. We present the case of a 54-year-old female patient with intestinal occlusion due to incarcerated femoral hernia, repaired by laparoscopic approach, that gave the patient the opportunity to attend her daughter’s wedding the same day.
Small Supernumerary Marker Chromosome (sSMC) is a rare genetic condition marked by the presence of an extra chromosome to the 46 human chromosomes. This case report describes a 4 year old child with SSMC on the 46th chromosome. The child presented with delayed speech and language development, seizures and mild developmental delay. Speech and Language evaluation was carried out and management options are discussed.
A catheter is a thin tube made from medical grade materials that serve a broad range of functions, but mainly catheters are medical devices that can be inserted in the body to treat disease or perform surgical procedures. Catheters have been inserted into body cavities, ducts, or vessels to allow for drainage, administration of therapeutic fluids or gases, operational access for surgery. Catheters help perform tasks in various systems such as cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic systems. A dataset of 12 patients with varying “weights” and “heights” was recorded along with the lengths of their catheter tubes. This data set was found from two revered statistical textbooks on linear regression and the Department of Scientific Computing at Florida State University. This data set was not able to be linked to any particular clinical or experimental research studies, but the data set can be used to help catheter manufacturers and medical professionals better decide on what particular catheter lengths to use for patients knowing only their height & weight. These research insights could be helpful to healthcare professionals that have patients with incomplete or no healthcare records
to decide what catheter length to use. The main investigative inquiry that needed to be answered was how does patient weight & height influence catheter length together and separately? We conducted linear regression and other statistical analysis procedures in R program & Microsoft Excel and discovered that this data exhibited a quality called multi collinearity. With multi collinearity, all predictors (2 or more
independent variables) are not significant in an all encompassing linear aggression, but the predictors might be significant in their own individual linear regressions. Individual linear regression analyses were conducted for both patient height & weight to see how much they both contribute to varying catheter length. Patient weight was found to be more impatful than patient height in relationship to catheter length, even though height and weight are a classical example of multi collinearity predictors.
Bovine mastitis has a negative impact through economic losses in the dairy sector across the globe. A cross sectional study was carried out from September 2015 to July 2016 to determine the prevalence of bovine mastitis, associated risk factors and isolation of major causative bacteria in lactating dairy cows in selected districts of central highland of Ethiopia. A total of 304 lactating cows selected randomly from five districts were screened by California Mastitis Test (CMT) for subclinical mastitis. Based on CMT result and clinical examination, over all prevalence of mastitis at cow level was 70.62% (214/304).
Two hundred fourteen milk samples collected from CMT positive cows were cultured for isolation of major causative bacteria. From 214 milk samples,187 were culture positive and the most prevalent isolates were Staphylococcus aureus 42.25% (79/187) followed by Streptococcus agalactiae 14.43%
(27/187). Other bacterial isolates were included Coagulase Negative Staphylococcus species 12.83% (24/187), Streptococcus dysgalactiae 5.88% (11/187), Escherichia coli 13.38% (25/187) and Entrococcus feacalis 11.23% (21/187) were also isolated. Moreover, age, parity number, visible teat abnormalities,husbandry practice, barn fl oor status and milking hygiene were considered as risk factors for the occurrence of bovine mastitis and they were found significantly associated with the occurrence of mastitis (p < 0.05). The findings of this study warrants the need for strategic approach including dairy extension that focus on enhancing dairy farmers’ awareness and practice of hygienic milking, regular screening for subclinical mastitis, dry cow therapy and culling of chronically infected cows.
Kratom is an herbal product that is derived from Southeast Asian Mitragyna speciose tree leaves [1-10]. This compound is used for many purposes such as stimulation, euphoria, or analgesia [1-10]. It has been recently identified as a drug of abuse by the United States Drug Enforcement Administration [2,8]. Side-effects from this compound have not been well documented. We describe a case of a 36-year-old female who develop nephrotoxicity after taking an herbal supplement. She took kratom as an adjunctive therapy for back pain management. She developed right upper quadrant pain and nausea. Laboratory tests showed elevated liver enzymes without evidence of bile duct obstruction. Liver enzymes normalized several weeks after Kratom discontinuation. We advise clinicians to be vigilant about Kratom’s hepatotoxic potential on patient health.
The assessment, diagnosis and treatment of critically ill patients is extremely challenging. Patients often deteriorate whilst being
reviewed and their rapidly changing pathophysiology barrages healthcare professionals with new data. Furthermore, comprehensive assessments must be postponed until the patient has been stabilised. So, important data and interventions are often missed in the heat of the moment. In emergency situations, suboptimal management decisions may cause signifi cant morbidity and mortality. Fortunately, standardisation and careful design of documentation (i.e. proformas and checklists) can enhance patient safety. So, I have developed a series of checklist proformas to guide the assessment of critically ill patients. These proformas also promote the systematic recording and presentation of information to facilitate the retrieval of the precise data required for the management for critically ill patients. The proformas have been modifi ed extensively over the last twenty years based on my personal experience and extensive consultation with colleagues in several world-renowned centres of excellence. The proformas were originally developed for use in the intensive therapy unit
or high dependency unit. However, they have been adapted for use by outreach teams reviewing patients admitted outside of critical care areas. The use of these tools can direct eff orts to provide appropriate organ support and provides a framework for diagnostic reasoning.
Systemic Hypertension (HTN) accounts for the largest amount of attributable Cardiovascular (CV) mortality worldwide. There are several factors responsible for the development of HTN and its CV complications. Multicenter trials revealed that risk factors responsible for Micro Vascular Disease (MVD) are similar for those attributable to Coronary Artery Disease (CAD) which include tobacco use, unhealthy cholesterol levels, HTN, obesity and overweight, physical inactivity, unhealthy diet, diabetes, insulin resistance, increasing age and genetic predisposition. In addition, the defective release of Nitric Oxide (NO) could be a putative candidate for HTN and MVD. This study reviewed the risk stratification of hypertensive population employing cardiac imaging modalities which are of crucial importance
in diagnosis. It further emphasized the proper used of cardiac imaging to determine patients at increased CV risk and identify the management strategy. It is now known that NO has an important effect on blood pressure, and the basal release of endothelial Nitric Oxide (eNOS) in HTN may be reduced. Although there are different forms of eNOS gene allele, there is no solid data revealing the potential role of the polymorphism of the eNOS in patients with HTN and coronary vascular diseases. In the present article, the prevalence of eNOS G298 allele in hypertensive patients with micro vascular angina will be demonstrated. This review provides an update on appropriate and justified use of non-invasive imaging tests in hypertensive patients and its important role in proper diagnosis of MVD and CAD. Second, eNOS gene allele and its relation to essential hypertension and angina pectoris are also highlighted.
Methods: Two groups were selected by non-probability random sampling technique including case group of 154 patients with
suspected dengue (fever>2days and <10days) and control group of 146 patients with febrile illness other than dengue. Clinical,hematological and serologic markers of cases and control groups were analyzed. The frequency distribution was used to compare categorical serologic markers and paired sample T test was applied for hematologic variables before and after treatment of dengue using SPSS version 21.
Researchers from Utrecht recently published yet another paper on the use of Magnetic Resonance Imaging (MRI)demonstrating an additional failed attempt to understand the importance of qualitative versus quantitative imaging, and anatomic versus physiologic imaging.

INTRODUCTION
Diabetes mellitus is a metabolic disorder characterized by
disturbances in carbohydrate, protein and lipid metabolism and
by complications like micro vascular (retinopathy, neuropathy and
nephropathy) and macro vascular (heart attack, stroke and peripheral
vascular disease) complications [1]. A worldwide survey has reported
that diabetes mellitus affects nearly 10% of the population. It has been
predicted that the prevalence of diabetes in adults will increase from
135 million in 1995 to 350 million in 2030 as given by International
Diabetes Federation [2,3]. Currently available synthetic antidiabetic
agents produce serious side effects like hypoglycemic coma and
hepatorenal disturbances [4,5]. Patients are therefore using herbal
medicines which have fewer side effects and have the potential to
impart therapeutic effect in complicated disorders like diabetes and
its complication [6]. Following the WHO’s recommendation for
research on the beneficial uses of medicinal plants in the treatment
of diabetes mellitus, investigations on hypoglycemic agents derived
from medicinal plants have also gained momentum. Traditional
medicinal plants with various active principles and properties have
been used from ancient times by physicians and laymen to treat a
great variety of human diseases such as diabetes, coronary heart
disease and cancer. Antidiabetic agents from medicinal plants could
serve as a good source for drug design and much attention has been
fixed on formulation of herbal medicine [7].
Plants are well known in traditional herbal medicine for their
hypoglycemic activities and available literature indicate that there
are more than 800 plant species showing hypoglycemic activity.
There has been increasing demand for the use of plant products with
antidiabetic activity due to low cost, easy availability and lesser side
effects. Therefore, plant materials are continuously scrutinized and
explored for their effect as hypoglycemic agents. One such plant is
Coriandrum sativum which has been used in Traditional System of
Indian Medicine for treating diabetes.
Coriander [Coriandrum sativum Linn.] an annual of the Apiaceae
family is one of the valuable medicinal and seasoning plant. This
species comes from the Mediterranean region and it is grown all
over the world. The coriander fruit and essential oil isolated from
it are used for medicinal purpose [8,9]. C.sativum is widely used in
traditional medicine to treat anxiety, dizziness, headache, edema,
fever, digestive disorders, respiratory diseases, allergies, and burns
[10,11]. The fruits are used as astringent, anthelmintic, emollient,
stomachic, antibilious, digestive, appetizer, constipating, diuretic,
antipyretic, refrigerant, tonic, expectorant, anodyne, antidiabetic
and dyspepsia. The phytochemical screening of Coriandrum sativum
showed that it contained essential oil, tannins, terpenoids, reducing
sugars, alkaloids, phenolics, flavonoids, fatty acids, sterols, glycoside,
wide range of minerals, trace elements and vitamins. The previous
pharmacological studies revealed that it possessed anxiolytic,
antidepressant, sedative-hypnotic, anticonvulsant, memory
enhancement, improvement of orofacial dyskinesia, neuroprotective,
antibacterial, antifungal, anthelmintic, insecticidal, antioxidant,
cardiovascular, hypolipidemic, anti-inflammatory, analgesic,
antidiabetic, mutagenic, antimutagenic, anticancer, gastrointestinal,
deodorizing,dermatological,diuretic,reproductive,hepatoprotective,
detoxification and many other pharmacological effects[12-17].
Silver nanoparticles were synthesized using methanol and
aqueous extract of fruit of C.sativum and its antioxidant activity were
reported [18]. We have reported better activity with 75 % methanol
extract of fruit of C.sativum and HPTLC data also showed that 75
% methanol extract has more number of phytoconstituents than all
other extract [13]. The 75 % methanol extract showed significant
decrease in blood glucose level at a dose of 100 mg/kg and 200 mg/kg.
It also decreased the lipid parameters such as total cholesterol, total
triglycerides, total bilirubin, SGOT, SGPT and ALP when compared
with diabetic control. 75% methanol extract at 100 mg/kg was better
in controlling diabetes when compared to 200 mg/kg bw suggesting
that C.sativum possess antidiabetic activity [19,20].
Molecular docking is an important computational tool to
predict the plausible interactions between the drug and protein in
a non-covalent fashion. An in silico docking procedure have been
carried out to examine whether the compound is a good ligand with
diabetic target Glutamine: fructose-6-phosphate amidotransferase.
Glutamine: Fructose-6-Phosphate Amidotransferase (GFAT) is a
rate-limiting enzyme in the hexoamine biosynthetic pathway and
plays an important role in type 2 diabetes. The enhanced activity of
human GFAT has been implicated in insulin resistance in cellular and
animal models. Thus, human GFAT is recognized as an interesting
ABSTRACT
Background and aim: Diabetes Mellitus [DM] is a metabolic disorder characterized by disturbances in carbohydrate, protein and
lipid metabolism and by complications like micro vascular (retinopathy, neuropathy and nephropathy) and macro vascular (heart attack,
stroke and peripheral vascular disease) complications. Coriandrum sativum Linn has been claimed to possess antidiabetic properties in
Traditional System of Medicine. This study aimed to evaluate molecular interaction of linalool in C.sativum and targeted protein related
to Type 2 DM.
Material and Methods: Isolation of Linalool from the methanol extract of fruit of C.sativum was done by column chromatography.
Evaluation of hypoglycemic activity through an in silico docking approach with molecular target such as glutamine: fructose- 6-phosphate
amidotransferase was performed. Molecular docking study was performed with Autodock docking software.
Results: The docking studies of the ligand linalool with target protein showed that this is a good inhibitor, which docks well related to
diabetes mellitus with -2.0297kJ mol-1
Van der waal energy and -5.9265 kJ mol-1
as docking energy. Hence linalool can be considered for
developing into a potent anti-diabetic drug.
Conclusion: Management of diabetes is challenge to the medical treatment. This leads to increasing demand for natural products
with antidiabetic activity with fewer side effects. This work establishes C.sativum extract as a potential inhibitor for diabetes. Thus
enabling a possibility of this plant extract as a new alternative to existing diabetic treatment.

potential target for type 2 diabetes complications. Glutamine-
Fructose-6-Phosphate Amidotransferase (GFAT or GFPT) is the first
and rate-limiting enzyme of the hexosamine pathway. GFAT controls
the flux of glucose into the hexosamine pathway and catalyzes the
formation of glucosamine 6-phosphate. The majority of glucose
will enter the glycolysis pathway, with a small percentage entering
the hexosamine pathway. GFPT or GFAT regulate the hexosamine
pathway products. Therefore, this enzyme involved in a therapeutic
target against Type 2 DM [21].
The aim of present study was to isolate Linalool from methanol
extract of C.sativum. To the best of our knowledge, this is the first
report on docking studies of the compound Linalool isolated from
C.sativum for antidiabetic activity.
MATERIALS AND METHODS
Plant material
The Coriandrum sativum fruits were collected from local
market in Bangalore, Karnataka, India and it was identified and
authenticated by Botanist, Natural Remedies Pvt Ltd., Bangalore. A
voucher specimen was deposited in The Oxford College of Pharmacy,
Bangalore. The fruits were dried in shade and powdered coarsely,
passed through sieve no. 40 and stored in air tight container for
further use.
Preparation of fruit extract
Coarsely powdered fruits of C.sativum 200 g was extracted with
75 % methanol [1500 ml] in soxhlet apparatus till the complete
exhaustion, filtered. The methanol extract was concentrated by rotary
vacuum evaporator and evaporated to dryness.
Chemicals used
All chemicals and solvents used were of analytical grade and
procured from SD fine Chemicals Ltd, Mumbai.
Isolation of Linalool
75% methanol extract was subjected to column chromatography
using solvents of increasing polarity as eluent and Silica gel as
stationery phase. Fraction from 68-79 from petroleum ether: Benzene
(98:2) yielded colorless liquid [100 mg; 0.5 %] which was found to be
linalool and confirmed by Co-TLC and already it was observed in Gas
chromatography [22].
Sequence retrieval
Authentic structures for Ligands were retrieved from Protein
data bank. The three dimensional structure of target protein was
downloaded from PDB (www.rcsb.org/pdb) structural database.
This file was then opened in SPDB viewer edited by removing the
heteroatoms, adding C terminal oxygen. The active pockets on target
protein molecule were found out using CASTp server. The ligands
were drawn using ChemDraw Ultra 6.0 and assigned with proper 2D
orientation (ChemOffice package). 3D coordinates were prepared
using PRODRG server.
Ligand binding site prediction
Ligand binding sites were calculated using Q site finder http://
www.modelling.leeds.ac.uk/ qsitefinder/, surface topology and the
pocket information were also analyzed by the cast P server http://
sts-fw.bioengr.uic.edu/castp/calculation.php. Pocket detection and
occupancy of the protein was set up using Q-Site Finder. Clefts were
tarnished in the protein-surface using Q-SiteFinder. The Solvent
Available Surface Area (SASA) was found by the software server
GETAREA http://curie.utmb.edu/getarea.html. The atomic Solvent
Accessible Surface Area (SASA) enclosed by each cleft was calculated
by utilizing radius of water probe 1.4 A0
and the area/ energy per
residue was also designed. Dielectric constant was set to a value of
80.0, and Poisson-Boltzmann method of computation for 20 cycles
was used for calculating the electrostatic potential in SWISS-PDB
viewer. All the ligand binding residues were amongst hotspots as
predicted by Meta-PPISP. Furthermore, PIC was made to use to
calculate the nature of interaction occurring in the ligand binding
residues.
Docking studies
Autodock V3.0 was used to perform Automated Molecular
Docking in AMD Athlon (TM)2x2 215 at 2.70 GHz, with 1.75 GB
of RAM. AutoDock 3.0 was compiled and run under Microsoft
Windows XP service pack 3. For docking, grid map is required in
AutoDock, the size of the grid box was set at 102, 126 and 118 Å (R,
G, and B), Comparative availability of 3D structures was checked in
NCBI Entrez, along with PDB and SWISSPROT databases [23].
Assessment of protein-ligand interaction
Hydrogen bond interactions were calculated by using Discovery
studio (http://accelrys.com/products/discovery-studio) and ligand
map was generated using MOLEGRO (http://molegro-molecular-
viewer.software.informer.com/2.5/).
RESULTS AND DISCUSSION
Linalool was isolated from 75% methanol extract of C.sativum
fruits. The structure is given in the (Figure 1). It was obtained as
colorless liquid, bp:1980
C [lit bp: 198-1990
C], refractive index:
1.460[lit refractive index: 1.463]. Molecular formula: C10
H18
O and
molecular weight: 154. It was confirmed to be Linalool by Co-TLC.
Linalool is a major and common terpenoid contained in most
herbal essential oils and teas, including both green and black teas,
and has been implicated in aroma and flavoring [24]. Oral exposure
to linalool from formulated food products, including beverages,
was estimated at up to 140 μg/kg/day, including the dietary intake
of linalool from natural sources such as vegetables and spices [25].
Linalool has been traditionally used for medicinal purposes because
of its potent antioxidative activities [26,27]. Recent studies have
suggested that linalool may have a novel biological activity in TG
metabolism, as the oral administration of fragrant herbal essential
oils containing linalool, including Plantago asiatica and Melissa
officinalis essential oils, was shown to improve dyslipidemia by
reducing plasma TG concentrations [28].
In silico molecular docking studies
In order to investigate the binding capacity of Linalool in
C.sativum on proteins related to diabetes in humans, we docked the

compound to the target protein. Results showed that docking of the
molecule with -2.0297kJ mol-1
Vander waal energy and -5.9265 kJ
mol-1
as docking energy (Table 1). High binding affinity of the ligand
to the receptor was explained clearly by interaction analysis in (Figure
2, Figure 3 and Figure 4).
Glutamine: fructose-6-phosphate amidotransferase (GFAT) is
the key enzyme in the hexoamine biosynthetic pathway and plays an
important role in type 2 diabetes [29]. In our study, docking of novel
compound with 2ZJ3 showed van der Waal interaction with ALA
674, CYS 373, THR 425, GLY 374, SER 376, THR 375, SER 473, SER
676, VAL 471, LYS 675 and GLU 560.
GFAT plays a key role in hexosamine biosynthetic pathway, which
is involved in glucose-induced insulin resistance and the induction of
the synthesis of growth factor. The hexosamine pathway is the sensor
of the glycoglysis pathway, in the reaction of fructose-6-phosphate
(F6P) with the NH2 donor amino acid, a glutamine which is converted
to Glucosamine-6-Phosphate (GlcN6P) by the Glutamine Fructose-
6-Phosphate Amidotransferase (GFA) enzyme. Subsequent reactions
result in the formation of uridine diphosphate N-acteylglucosamine
(UDP-GlcNAc) which is utilized as a substrate for N- and O-linked
glycosylation. It is intracellular protein O-Glycosylation Mediated
By O-Linked Glcnac Transferase (OGT) which has been postulated
to contribute to glucose toxicity by altering gene expression. The
synthesis of glucosamine begins with the transport of glucose into
the cell and its conversion to glucose-6-phosphate by hexokinase
and then isomerization to fructose-6-phosphate by the enzyme
phosphofructose kinase I of the glycolysis pathway. Then fructose-
6-phosphate can go through the normal metabolic pathway as
previously described in glucose metabolism. Due to the hexosamine
pathway, 2–5% of fructose-6-phosphate formed in glycolysis is
converted to glucosamine. Fructose-6-phosphate is isomerized and
aminated by glutamine and GFAT (L-glutamine, D-fructose-6-
phosphate amidotransferase) to yield glucosamine- 6-phosphate.
First, Acetyl-Coenzyme (CoA) from either glucose metabolism
or fatty acid oxidation transfers its acetyl group to glucosamine-6-
phosphate to produce N-acetylglucosamine-6-phosphate. Then, a
Uridine Nucleotide (UDP) is added to the glucosamine yielding
Uridine 50-Diphospho-N-Acetylglucosamine (UDP-GlcNAc).
Overall the production of UDP-GlcNAc requires glucose, glutamine,
acetyl-CoA, uridine, and ATP. Studying the interaction of GFAT
with UDP-GlcNAc and its 3D structure will provide more chances to
develop a new strategy for treatment of type 2 diabetes. The majority
of glucose will enter the glycolysis pathway, with a small percentage
entering the hexosamine pathway. Hexosamine biosynthesis is
known to contribute to insulin resistance and the induction of the
synthesis of growth factor. GFPT or GFAT regulate the hexosamine
pathway products. Therefore, this is involved in a therapeutic target
against type 2 diabetes [21].
CONCLUSION
Renewed interest on the use of herbal products is gaining
importance. Globally, many herbal products are being used as food
supplements for prophylaxis of common ailments such as diabetes,
hypertension etc.
Prior to the pharmacological investigation of any herbal product it
is mandatory to investigate the safety profile of these herbal products.

It is documented that if an herbal substance is free from side effects
or adverse effects up to 2000 mg/kg, it is considered safe for clinical
use, the absence of acute toxicity is observed thus proving the safety
profile of C.sativum.
The 75 % methanol extract showed significant decrease in blood
glucose level at a dose of 100 mg/kg and 200 mg/kg. It also decreased
the lipid parameters such as total cholesterol, total triglycerides,
total bilirubin, SGOT, SGPT and ALP when compared with diabetic
control. 75% methanol extract at 100 mg/kg was better in controlling
diabetes when compared to 200 mg/kg bw suggesting that C.sativum
possess antidiabetic activity. This was further confirmed by isolating
Linalool from the methanol extract. This compound was found to
interact the target protein which can be related to DM with -2.0297kJ
mol-1
Vander waal energy and -5.9265 kJ mol-1
as docking energy.
Docking studies of the linalool with target protein showed that this
is a promising candidate which docks well with the target related to
diabetes mellitus. Thus Linalool can be considered for developing
into a potent antidiabetic drug.
