1) The study evaluated the alkaloid extracted from carica papaya leaves as a platelet stimulator by isolating the alkaloid and testing its effects on platelet count in rats.
2) Phytochemical screening of the aqueous extract of carica papaya leaves showed the presence of glycosides, tannins, alkaloids, saponins and flavonoids.
3) Administration of the isolated alkaloid to rats resulted in a significant increase in platelet count, from an average of 44,166 platelets/mm3 to 128,000 platelets/mm3.
Hematological and Liver Function of Plasmodium Berghei Positive Wister Treate...ijtsrd
Eradication of malaria in Africa continues to be one of the greatest challenges in the health sector. All the drugs developed thus far have their limitations and are generally expensive. In Africa and Nigeria the use of herbs in treating sicknesses dated as far back as the existence of man and is still in use today by many Nigerians in rural areas. Here we evaluated the therapeutic efficacy of ethanolic extract for three of these herbs lemon grass, lime and turmeric used singly and in combination on Plasmodium berghei infected rats. Results reveals that there was an 81.54 reduction in parasite level in groups treated with herbs and an 88.9 reduction in those treated with ACTs. The time frame of this study wasn’t enough to determine if there will be a resurgence in the parasitemia level. Results from the liver function test also reveals that the herbs also reduced the levels of liver enzymes in the serum but the results from the liver histology from the onset shows little or no damage to the liver This helps us to understand that the plasmodium parasites does not cause much damage to the liver cells or requires more time to do so. Hence the study concludes that potent herbs like turmeric, lemon grass and lime although not as effective as ACTs but if harnessed properly can be substituted for ACTs in treating malaria in low income rural areas of Nigeria.

Abstract
In recent times, there is an extensive interest in these Alcoholic extracts due to the emergence and spread of new drugresistant human pathogens to existing antimicrobials. The emergence of medicine opposing pathogens is one of the mostcritical threats to booming treatment of bacterial diseases. Mode of action of Methanolic extracts likely involves fairly a lotof targets in the cell due to huge number of active components and also their hydroplillicity helps them to screen in the cellmembrane, rendering them permeable , leading to leakage of cell contents. This calls for a transformed effort to identifyagents efficient against disease causing bacteria to present antimicrobials. Seed extracts of two different plants viz. Phoenixdactylifera and Annona squamosa, were prepared by methanol extraction method at the ratio of 1:2 using 100ml volume of methanol and stock concentration of 50mg/ml in dimethyl sulfoxide (DMSO) of each extract was made.The extracts and fractions were tested for antimicrobial activity against standard microbial strains of Klebsiella pneumoniae (gramnegative), Staphylococcus aureus (gram-positive), Escherichia.coli (gram-negative), Salmonella typhi (gram-negative) , Enterococcus faecalis (grampositive), Pseudomon aerugenosa (gram-negative),and Salmonella paratyphi (gram-negative)by means of Agar-Disc Diffusion Method and minimal inhibitory concentration (MIC) was noted .. The test culture of standard microbial cultures was 3 X 105 CFU/ml, and standard antibiotic used is Ampicillin with clavulanic acid. In this context, two extract from traditional plants, Custard Apple (Annona squamosa) and Dates (Phoenix dactylifera) were used alone or in combination to assess their antimicrobial efficacy against both Gram negative and Gram positive bacterial clinical isolates .Antimicrobial test was completed by agar disc diffusion method. Although, both extract were found to be effective in inhibiting pathogens to varying degrees to the tested organisms, the Annona squamosa extract is found to be more effective than Phoenix dactylifera.When both extracts were used in combination, they have shown strong synergistic effect against all the pathogens tested in the present studyexcept for the P.aerugenosa and S. Para typhi. Bactericidal abilities displayed by the seed extracts signified their remarkable potential for exploration for effective natural antimicrobial agents against standard pathogenic bacteria. The extracts have shown the synergistic effects even at their MIC against E.fecalis, indicating that with further researches these extracts can be used for treating enteric diseases.

The effects of co-administration of Azadirachta indica and Gongronema latifolium on the liver of Plasmodium beighei infected Swiss albino mice was evaluated. Thirty mice divided into 6 groups of 5 animals each were used for this study. Healthy control group was not infected with. Other group was infected by intraperitoneal injection of P. beighei. Once parasitaemia was confirmed, treatment groups were assigned; Group A received distilled water at 10ml/kg body weight. Group B was not given any extracts. Groups C was given G.latifolium extract at 500mg/kg body weight. Groups D was given A. indica extract at 500 mg/kg body weight. Group E received both extracts at 500 mg/kg each. Group F received Artemether at 1.6mg/kg body weight intraperitoneally. The extracts were administered orally for 5 days. The animals were sacrificed after blood was obtained for serum liver enzymes estimation. The liver were processed for histological study using H and E. Histology of the liver showed sinusoidal congestion and hepatocyte necrosis in the diseased control and steatosis, loss of normal sinusoidal architecture, necrosis of hepatocytes and portal tract inflammation in the A. indica only group. The groups administered G. latifolium, both singly and in combination with A. indica had normal liver histology. The liver enzyme ALT was significantly (p<0.05) raised in A. indica treated group while it was normal in the G. latifolium groups. It will thus appear that G. latifolium ameliorated the hepatotoxicity of A. indica in Plasmodium beighei infected mice.
Antiplasmodial activity of methanol leaf extract of Salacia senegalensis Lam ...Premier Publishers
The antiplasmodial effect of methanol leaf extract of Salacia senegalensis were evaluated in albino mice infected with chloroquine-sensitive Plasmodium berghei berghei (NK65) in order to justify or otherwise its use as antimalarial remedy in Nigeria folk medicine. Activities investigated were suppressive effect against early infection, curative effect against established infection and prophylactic effect against residual infection. Results showed a dose dependent blood schizontocidal activity at all the phases of malarial infection studied. The in vivo antiplasmodial effect of the extract (1000, 1200 and 1400 mg/kg body weight) against P. berghei showed significant (p < 0.05) dose-dependent activity for suppressive, curative and prophylactic test. When the extract dose increased from 1000 to 1400 mg/kg/day, chemosuppressive activity of the extract increased from 66.47 % to 80.33 %. There was also an increase from 66.57 % to 75.41 % and from 64.90 % to 82.72 % for the repository and curative activities respectively. The schizontocidal activities were comparable to that of chloroquine -which had percentage suppression of parasitaemia as 87.03 %, 85.12 %, and 91.68 % for suppressive, prophylactic and curative activities respectively). It was thus concluded that the herbal extract possesses significant antimalarial potency which could be exploited in the formulation of antimalarial drugs.

ABSTRACT- Medicinal Plants have been practiced for hundreds of centuries by tribes all over the world. From the earliest times until the end of nineteenth century plants are still the common source of medicinal treatment yet. Using natural, plant-derived medicines that are “healthier” then prescription drugs derived from synthesized products is something that appeals to consumers. The medicinal plants are of great importance because there are utilized as medicines. Aim of this research work was to evaluate the antibacterial activity of Skimmia laureola plant against various patho-genic strains of bacteria. The hot and cold water extract of Skimmia laureola were used against four bacterial strains Escherichia coli,Bacillus subti-lus, Staphylococcusaureus and Proteus mirabilis in order to check the antibacterial activity of Skimmia laureola. Antibacterial activity was conducted by agar well diffusion method. The Skimmia laureola showed different level of antibacterial activity. The hot and cold water extract of Skimmia lau-reola showed antibacterial activity against the micro-organism but not too maximum. Keywords: Medicinal Plants, Skimmia Laureola, Antibacterial Activity.

Reducing Postharvest Softening of Papaya (Carica papaya cv. Maradol) by using...Agriculture Journal IJOEAR
Abstract— The shelf life of ‘Maradol’ papaya fruit (Carica papaya) harvested at one-quarter stage maturity (yellow-orange color in 25% of fruit surface) and treated with aqueous 1-methylcyclopropene (1-MCP) was evaluated. The effects of immersion time (30 or 60 seconds) and dose response (50 or 300 ng∙kg-1) on the quality of papaya fruit stored for 12 days at 20 ± 2 °C and 85 ± 5% RH were studied. After 3 days, the control and fruit treated with 50 ng∙kg-1 1-MCP for 30 seconds lost 82% and 72% of the initial firmness, respectively. A 1-MCP concentration of 300 ng∙kg-1 for 30 or 60 seconds inhibited softening and slowed skin color change for 12 days. The pH, titratable acidity, and soluble solids concentration ranged from 5.3-5.7, 0.06-0.12 % and 10-12 %, respectively. The shelf life of papaya was extended up to 3 days in fruit treated with 50 ng∙kg-1 1-MCP for either 30 or 60 seconds of immersion.

Study the efficacy of Rhizophora mucornata Poir. leaves for diabetes therapy ...Open Access Research Paper
Hypoglycemic effects were investigated in the ethanol extract of leaves of Rhizophora mucornata on Long Evans rats. Gut perfusion and six segments studies were carried out to assess these activities. In the gut-perfusion study the percentage of glucose absorption in control rats vs. rats fed with 250 mg/kg extracts were observed at 5, 10, 15, 20, 25 and 30 minutes and the significant (p<0.05) absorption result was found at 15 minutes, which was 35.87 vs. 57.29. The percentage of absorption was found better with 250 mg/kg than 500 mg/kg dose level. The six-segment study was performed to assess the amount of sucrose remaining in the GIT at six different positions. The amount sucrose unabsorbed in different GIT segments showed that in control rats vs. rats fed with 500mg/kg extract at 30 minutes in mmol/l was 0.120 vs. 0.135 which were gradually abating with time dependent manner at 60, 180, and 360 minutes in mmol/l. These results suggest that ethanol extract of leaves of Rhizophora mucornata has significant dose dependant anti-diabetic effects which may be effective in the treatment of diabetes.
Mormodica charantia Linn. A Potential Antibiotic and Anti-Fungal Druginventionjournals
Resistant or multi resistant strains are continuously appearing in the treatment of ailments and this necessitates the synthesis of new drugs especially from naturally occurring plants. Momordica charantia is a very common indigenous plant of tropical and sub-tropical regions of the world. Phytochemical screening, antimicrobial analysis were conducted using recommended procedures. Ethanol and water were used for the extraction and Ultraviolet Visible and Infrared Spectroscope were used to identify the functional groups. Alkaloids, flavonoids, saponins, tannins, anthraquinones were all present in both the ethanolic and aqueous extracts, terpenoids was only present in aqueous extract while cardiac glycosides was not present in both extracts. Concentration (200mg/ml) revealed the highest clear zone of inhibition in both aqueous and ethanol extracts. The zone of inhibition increases with increase in concentration of sample. The ethanol extract shows the higher clear zone of inhibition when compared to aqueous extract with a diameter of zones of inhibition of 28, 26, 24, 26, 26 and 24mm for Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginesa, Salmonella typhi and Klebsiella pneumoniae respectively. The aqueous extract has no effect at concentration (6.25mg/ml) because no clear zone of inhibition was measured. The antimicrobial activity for aqueous extract was lower than and not as effective as ethanol extract because ethanol is a phenolic compound and non-polar solvent when compared with water that is a polar solvent. Infrared spectra showed OH stretch due to phenol was observed at 3702 cm-1 , - C - H stretch (alkane) at 2972cm-1 , C - H bending vibration (alkane) at 1381cm-1 , - C - N and – C = N at 2077cm-1 , NH stretching at 3375cm-1 . The results indicate that it contained a phenolic, amine and amide substitute. Therapeutic drugs with antibiotic and antifungal activities can be synthesized from Mormodica charantia.

The properties of papaya fruit and other parts of the plant are also well known in traditional system of medicine. Papaya possess excellent medicinal properties for treatment of different ailments. These curative properties are based on the presence of phytochemical nutrients with antioxidant effect in different parts of the plant. It is considered as valuable nutraceutical fruit plant due to its biological activity and medicinal application.The present study was designed to determine the Cytoprotective and DNA protective activities of different fractions (Aqueous, Chloroform, Ethanol and Ethyl acetate extracts) of Carica papaya leaves. Cytoprotective capacity was assessed using erythrocytes, where ferrous sulphate was used to induce stress and the ability of the extracts to combat the induced stress was evaluated. The DNA protective potential against free radical-mediated oxidative stress was evaluated by a DNA damage inhibition assay involving agarose gel electrophoresis and UV spectrophotometric analysis. All the four fractions displayed significant cytoprotective effect on erythrocytes and prevented oxidative damage to DNA in presence of DNA damaging agent. Altogether, the results of our study lend pharmacological credence to the anti-cancerous and ethno medical use of this plant in traditional system of medicine and these resultscould be used to develop antimutagenic compounds for cancer therapy.

Evaluation of Analgesic Activity of Moringa Oleifera Lam. Stem Bark Extract b...QUESTJOURNAL
Abstract: Moringa oleifera Lam. is also known as ‘Miracle tree’ because of its uses of all parts particularly for their great potential in pharmacological, nutritional and water purification aspects. The study has been done for the phytochemical screening and analysis of analgesic potential of Moringa olifiera Lam. methanolic stem bark extract using Acetic acid induced Writhing method. Qualitative chemical analysis was carried out through phytochemical investigation which indicated the presence of carbohydrates, glycosides, saponins, flavonois, tannins, proteins, alkaloids etc. in the extracts. To study analgesic activity Acetic acid induced Writhing test was used, where Methanolic stem bark extract was introduced intraperitonially at doses of 150 mg/kg and 300 mg/kg to Swiss-albino mice. The dose of 300 mg/kg showed significant inhibition of Writhing response created by acetic acid in a dose dependent manner when compared to the standard control drug Diclofenac Sodium. Those two different doses exhibited 5% and 80% inhibition in writhing response respectively while the Diclofenac Na inhibited about 46.25% of writhing response at a dose of 40 mg/kg of body weight. The results of this study support the potential pain management therapy using this crude extract.

• INTRODUCTION
• EXPERIMENTAL WORK AND DISCUSSION
• RESULT
• CONCLUSION
• FUTURE SCOPE
3. AIM :
To isolate alkaloid from carica papaya leaves
and to evaluate its effect on platelet count.
OBJECTIVES :
• To compare activity of aqueous and
methanolic extract of carica papaya leaves.
• To perform phytochemical screening of
aqueous extract of carica papaya leaves.
• To isolate alkaloids and evaluate its effect on
platelet count.
4. Introduction :
DENGUE FEVER:
• Spread through bite of Aedes egypti mosquito
carrying flavivirus.
• Flavivirus is divided into 4 types: DEN-1, DEN-
2, DEN-3 and DEN-4.
5. TRANSMISSION
•Infected person → mosquito → person
•From organ or blood donation
•From mother to child during pregnancy
RISKS
• Babies and young children than adults
• Women than men
• People with chronic disease like diabetes and asthma
6. MECHANISM
• In severe conditions, virus
production is increased →
affect liver and bone marrow
• Capillary permeability → fluid
from bloodstream leaks into
body cavity → low B.P.
• Dysfunction of bone marrow
→ decreased no. of platelets
( necessary for blood clotting )
→ increase risk of bleeding
7. SYMPTOMS: 4-10 days after the bite of infected
mosquito
• Sudden, high fever
• Severe headaches
• Pain behind the eyes
• Severe joint and muscle pain
• Nausea and Vomiting
• Skin rash
• Mild bleeding (such a nose bleed, bleeding gums, or easy
bruising)
• Severe abdominal pain
• Problems with your lungs, liver and heart
8. DIAGNOSIS
• Isolating the virus by collecting serum sample
• Detection of specific antibodies by ELISA from
serum
• PCR- for detecting viral genomes sequence from
serum & CSF
• Tourniquet test
• Thrombocytopenia ( i.e. Platelets < 1,00,000/mm3)
9. TREATMENT
• No known antiviral drugs or injections
• Antipyretics such as paracetamol & analgesics can be
used
• Papaya leaves, kiwi to increase platelet count
• Plenty of fluids can be given because dehydration occurs
• Drugs such as aspirin & ibuprofen should be avoided as
they may increase the risk of hemorrhage.
10. VACCINES : SANOFI PASTEUR VACCINE
• Live attenuated tetravalent vaccine
• It is in phase Ш clinical trials
Challenges to vaccine development
• Secondary heterotypic infection → increased risk of
severe disease
• Hence, vaccine development focuses on tetravalent
vaccine generation against all serotypes
11. PREVENTION
• Stay away from heavily populated residential areas, if
possible.
• Use mosquito repellents
• Wear long-sleeved shirts and long pants tucked into
socks.
• Use mosquito nets.
• Get rid of places where mosquitoes can breed such as old
tires, cans or flower pots that collect water.
• Bleaching powder may be used in water sources that are
not meant for drinking, as it prevents the development of
mosquito eggs
• If you have symptoms of dengue, speak to your doctor.

phytochemicals can be extracted more when the leaves are dried
and pulverized to powered form.
2) Debarati Guha-Sapir (et al, 2005): reviewed the changing
epidemiology of the disease, focusing on host and societal
factors and drawing on national and regional journals as well as
international publications
