ABSTRACT- The present study was planned to study the antimicrobial activity of different plant extract against selected microorganisms. The plants used in the present study were Ocimum sanctum (Tulsi), Withania somnifera (Ashwgandha), Santalum album (Chandan), Aloe vera (Aloe barbadensis), and shatavari (Asparagus racemosus). The extract from the leaves of these plants (are) used in malaria, bronchitis, gastric disorders, cough, cold etc. To test efficiency of some common plants extract against E. coli, Salmonella typhi, Proteus vulgaris, Staphylococcus aureus. Contrary to the synthetic drugs, antimicrobials of plant origin are not associated with many side effects and have an enormous therapeutic potential to heal many infectious diseases. The present investigation is therefore, undertaken to test the efficiency of some of the common plant extracts against some plants and human pathogens, i.e. E. coli and S. aureus. In this project work, we studied the different parts of medicinal plants of Latur, Osmanabad region used for curing different type of diseases specially skin diseases. Some plants have active components which show antimicrobial activity. These Herbal plants are beneficial to human being in therapeutic practice. Skin diseases are difficult conditions to live with, to save the very least. Though some skin diseases may cause minimal discomfort, the visual effects of the conditions can cause significant self esteem and confidence issues. The majority of skin diseases cause scarring or disfigurement. Skin diseases run the gambit from barely noticeable to fatal.

ABSTRACT- Background: Declining trend in semen quality is receiving attention worldwide. The aim of the study to investigate the role of lifestyle factors with respect to semen quality.
Methods: Semen samples were collected from 351 male partners attending OPD of Obstetrics and Gynecology at civil hospital and IKD hospital, Ahmedabad, India. They were subjected to assess the quality of semen according to WHO criteria and semen quality were analyzed with respect to self reported history of tobacco smoking and/or chewing and alcohol consumption as lifestyle factors.
Results: The result revealed that sperm count was lower in subjects with habit of tobacco smoking, chewing and alcohol consumption as compared to subjects without such habits and decline was found statistically significant among smokers. Total progressive motility and normal morphology percentage was significantly decreased in tobacco chewers compared to non-chewers. Further analysis of data with respect to alcohol consumption indicated non-significantly lower total progressive motility and normal sperm morphology percentage as compared to subjects with no such habit.
Conclusion: The data obtained suggested, the role of lifestyle factors especially tobacco smoking and chewing in declining semen quality.

In a prospective double blind randomized study we evaluated the prophylactic anti emetic efficacy of granisetron, a 5HT3 receptor antagonist and metoclopramide, a benzamide anti emetic on postoperative nausea and vomiting after major gynaecological surgery under general anaesthesia. The patients received a single dose of granisetron, 40mcg/kg (Group A, n = 25) or metoclopramide, 0.15mg/kg (Group B, n = 25) before induction of anaesthesia in a coded syringe. The response was assessed during 0-4 hrs, 4-8 hrs, 8-16hrs and 16-24 hrs time intervals after recovery from anaesthesia by means of presence or absence of nausea, retching or vomiting. The overall control of PONV during early postoperative period (0-4 hrs) did not show statistically significant differences after administration of either drug. The incidence of PONV during the next 20 hours was 12% and 48% with Group A (Granisetron) and Group B (Metoclopramide) respectively. Nausea scores are significantly lower in-group A (Granisetron) than in Group B (Metoclopramide) in all the four assessment periods. Although there were no emetic episodes in the granisetron group, 32% of patients in metoclopramide group were observed to have such episodes during the assessment periods. (P value< 0.05). No clinically important adverse events due to drugs were observed in any of the groups. In conclusion, the prophylactic use of granisetron is more effective and superior to metoclopramide in preventing postoperative nausea and vomiting in patients under going major gynaecological surgery under general anaesthesia.
A Comparative Study of Two-Sample t-Test Under Fuzzy Environments Using Trape...inventionjournals
This paper proposes a method for testing hypotheses over two sample t-test under fuzzy environments using trapezoidal fuzzy numbers (tfns.). In fact, trapezoidal fuzzy numbers have many advantages over triangular fuzzy numbers as they have more generalized form. Here, we have approached a new method where trapezoidal fuzzy numbers are defined in terms of alpha level of trapezoidal interval data and based on this approach, the test of hypothesis is performed. Moreover the proposed test is analysed under various types of trapezoidal fuzzy models such as Alpha Cut Interval, Membership Function, Ranking Function, Total Integral Value and Graded Mean Integration Representation. And two numerical examples have been illustrated. Finally a comparative view of all conclusions obtained from various test is given for a concrete comparative study.

This study elucidated the pharmacological potential of sea urchins using methanol as extracting medium. The antibacterial potential was evaluated using the paper disc method and zone of inhibition against Escherichia coli and Staphylococcus aureus was measured. Antioxidant properties of sea urchins were evaluated using DPPH radical scavenging assay. Three species of sea urchin randomly collected along the intertidal zone of Diguisit, Baler Aurora were identified using diagnostic keys by the National Museum of the Philippines and they were identified as follows; Echinothrix diadema, Echinometra mathaei, and Echinometra oblonga. E. diadema recorded the highest diameter zone of inhibition against E. coli and S. aureus after 24 hours of incubation with 11.03 ± 1.75mm and 13.52 ± 1.13mm respectively while E. mathaei only inhibited S. aureus with zone of inhibition of 9.27 ± 2.06mm in 24 hours of incubation as well. As the zone of inhibition prolongs, the zone of inhibition decreases as observed in 48 hours of incubation. E. oblonga did not show inhibitoy effect, however it recorded the highest radical scavenging activity with 64.46% among the three species of sea urchins. This was followed by E. mathaei (51.52%) and E. diadema (37.38%). All collected species manifested antioxidant potential. Based on the results, the collected species of sea urchins has a pharmacological potential.

The antibacterial activities of the methanolic, hot water, chloroform and petroleum ether extracts of
Choclospermum planchonii leaf were tested against some clinical bacterial isolates and reference organisms.
The phytochemical screenings of the extracts were also carried out. The leaf extracts of the plant exhibited
antibacterial activities against clinical isolates of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus
aureus, Shigella flexneri, and Salmonella typhii and reference strains of Staphylococcus aureus (ATCC 28923),
Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 27853. The methanolic leaf extracts
exhibited the highest antibacterial activity, its minimum inhibitory concentration (MIC) ranging between 0.31
and 1.25 mg/ml; and its zones of inhibition on the various test microorganisms ranging between 8mm and 13
mm. The petroleum ether extracts had the weakest antibacterial activity, its minimum inhibitory concentration
(MIC) ranging between 2.50mg/ml and 5.00mg/ml and its inhibition zone ranging between 4mm and 8mm. The
phytochemical constituents present in the plant were alkaloids, tannins, saponins, cardiac glycosides, and
sterols. The methanolic extracts of the leaf exhibited potentially biological activity than other extracts. This
indicates that the plant leaf could be useful in the treatment of human infections caused by these pathogens. The
antibacterial activities of the methanolic leaf extract may be attributed to the presence of bioactive compounds.

This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Abstract: Rheum rhabarbarum, which is commonly known as rhubarb, has been used as a medicinal herb in
different countries. Especially its roots are known to be a traditional medicine in different cultures. Mesir paste
was prepared about 500 years ago during Ottoman period as a medicinal paste and R. rhabarbarum was one of
its ingredients. In this study the in vitro antimicrobial activity of ethanol extract of R. rhabarbarum roots was
investigated against 17 bacterial and 1 fungal strain, namely, Bacillus subtilis DSMZ 1971, Candida albicans

I. INTRODUCTION
Using plants against diseases is assumed to be as old as human history. Today there is an increasing
interest by the scientists to define the secrets of these traditional herbal medicines [1]. The search for new
antimicrobial agents has increased mainly because of the increase in infections particularly in developing
countries with medically indigent populations and more so because of extensive bacterial resistance to current
antimicrobial agents [2]. It is a well-known issue that most of the antimicrobial agents are developed from
natural products, which have an antimicrobial potential [3, 4, 5]. Humankind without scientific knowledge
discovered new treatment methods through trial and error method in the history [6]. Mesir paste is a traditional
special mixture of several herbs and spices used as a medicine, which was founded about 500 years ago during
Ottoman period, including Terminalia citrina (black chuglam or citrine myrobalan), Zingiber officinale
(Ginger), Cuminum cyminum (Cumin), Angelica sylvestris (wild angelica) and Rheum rhabarbarum (rhubarb).
All ingredients of Mesir paste separately have been used for the treatment of various diseases in Turkish folk
medicine for long centuries [7]. In addition to this, especially the synergistic antimicrobial effect thought to be
the reason of Mesir paste’s healing effect.
World Health Organization (WHO) has predicted increasing antimicrobial resistance as a major threat
for the public health for the 21st
century [8]. In order to prevent spreading of antibiotic resistant infections,
scientists have been conducting intensive researches to determine new antimicrobial agents. One way to prevent
antibiotic resistance of microorganisms is by using new compounds that are not based on existing antimicrobial
agents [9, 10].
In this study the antimicrobial activity screening of R. rhabarbarum roots, one of the ingredients of
Mesir paste, is investigated against 17 bacterial and 1 fungal strains by using the disk diffusion method.
II. MATERIALS AND METHODS
Extraction Procedure
All R. rhabarbarum samples were ground by a pestle and a mortar. Ethanol (Sigma-Aldrich) was
chosen as an extraction solvent in order to extract active substances. Ground samples were shaken in the
extraction solvent at 90 rpm for 3 days. The extract was filtered through filter paper (Whatman No. 1) into
evaporation flasks. The filtrate was evaporated by a rotary evaporator at 38°C. After evaporation the residues
were collected and used to prepare 250 mg.mL-1
of ethanol extracts.

Microorganisms
A wide range of microorganisms were selected to test the antimicrobial effect of R. rhabarbarum.
These strains are Bacillus subtilis DSMZ 1971, Candida albicans DSMZ 1386, Enterobacter aerogenes ATCC
13048, Enterococcus durans, Enterococcus faecalis ATCC 29212, Enterococcus faecium, Escherichia coli
ATCC 25922, Klebsiella pneumoniae, Listeria innocula, Listeria monocytogenes ATCC 7644, Pseudomonas
aeruginosa DSMZ 50071, Pseudomonas fluorescence P1, Salmonella enteritidis ATCC 13075, Salmonella
infantis, Salmonella kentucky, Salmonella typhimurium SL 1344, Staphylococcus aureus ATCC 25923 and
Staphylococcus epidermidis DSMZ 20044.
The strains were chosen from standard strains as much as possible. Other strains which are not standard
were all isolated from food and identified in Ankara University, Faculty of Science, Department of Biology.
Preparation Of Inocula
All bacterial strains were incubated at 37 ˚C for 24 hours [11]. But since the requirements for C.
albicans is different, C. albicans was inoculated at 27 ˚C for 48 hours. Inocula were prepared by transferring
morphologically similar colonies of each organism into 0.9% sterile saline solution until the visible turbidity
was equal to 0.5 McFarland standard having approximately 108
cfu.mL-1
for bacteria and 107
cfu.mL-1
for C.
albicans [12-15].
Disk Diffusion Method
Disk diffusion test was performed as described previously by Andrews [16]. The culture medium was
poured into 90 mm sterile Petri dish to give a mean depth of 4.0 mm ± 0.5 mm [17, 18]. 50 µL and 100 µL
aliquots of extract was applied on sterile disks of 6 mm diameter end up with 12500 µg and 25000 µg sample on
each disk [19, 20]. To get rid of any residual solvent which might interfere with the results, disks were left to
dry overnight in sterile conditions [20, 21]. The surfaces of the plates were inoculated using previously prepared
inocula containing saline suspension of microorganisms. Inoculated plates were then left to dry for 5-6 minutes
at room temperature in aseptic conditions before applying the disks [22]. Disks were firmly applied to the
surface of the plate which had an even contact with the agar. Plates were incubated and inhibition zone
diameters were expressed in millimetres [23-24].
Controls
Empty sterile disks and extraction solvent (ethanol) loaded on sterile disks which were dried at sterile
conditions to remove solvent as done in the study were used as negative controls. Gentamicin 10 µg used as
positive control.
Statistics
All extracts were tested in triplicate and MACANOVA (version 5.05) was used for statistical analysis
of the data. P values of < 0.05 were considered statistically significant.
III. RESULTS AND DISCUSSION
The main aim of this study was to identify the antimicrobial activity of ethanol extracts of R.
rhabarbarum roots. To do this, disk diffusion test was performed in the study. In this test, extracts were loaded
on empty sterile disks and these disks were then applied on a culture medium inoculated with microorganisms.
If the extracts were shown activity against these microorganisms, they have caused an inhibition zone. The
diameters of the inhibition zones recorded in millimetres are given in Table 1. No activity was observed for the
negative controls; extraction solvent and empty sterile disks.

against S. infantis and S. kentucky where 100 µL (25000 µg.µL-1
) of R. rhabarbarum root samples caused an
inhibition zone of 29 mm against L. monocytogenes ATCC 7644, 28 mm against E. faecium, 20 mm against C.

innocula and S. enteritidis ATCC 13075, 11 mm against S. infantis and S. typhimurium SL 1344, 10 mm against
K. pneumoniae and S. kentucky.
It is observed that ethanol extracts of R. rhabarbarum root extracts has antimicrobial activity against all
microorganims tested.
Conter et al. [25] reported that L. monocytogenes strains are susceptible to the antibiotics commonly
used in human listeriosis treatment, but L. monocytogenes is slowly becoming antibiotic resistant and a
perpetual surveillance of emerging antimicrobial resistance of this pathogen is critical to ensure effective
treatment of human listeriosis. From this point of view, having antibacterial activity against L. monocytogenes
may very important. Ates and Erdogrul [26] identified that ethanol extract of Juniperus oxycedrus caused 7 mm
of inhibition zone against L. monocytogenes whereas Cinnamomum cassia, Glycyrrhiza glabra, Coriandrum
sativum and Pimpinella anisum observed no activity. On the other hand Gentamicin 10 µg caused 28 mm of
inhibition zone against L. monocytogenes. In our study we observed 23 mm zone for 12500 µg.µL-1
of R.
rhabarbarum roots and 29 mm zone for 25000 µg.µL-1
mg of R. rhabarbarum roots. Comparing these results
clearly presents that R. rhabarbarum roots are highly active against L. monocytogenes.
Enterococcus faecium has long been thought of as a harmless commensal of the mammalian GI tract.
However, E. faecium has become an important cause of nosocomial infections. These infections are often
difficult to treat owing to the resistance of E. faecium to a large number of antibiotics [27]. Mojab et al. [28]
identified that methanol extract of Thymus daenensis caused 8 mm of inhibition zone against E. faecium
whereas Ilhan et al. [29] identified that methanol extract of Palustriella commutata observed no activity. In our
study we observed 25 mm zone for 12500 µg.µL-1
of R. rhabarbarum roots and 28 mm zone for 25000 µg.µL-1
mg of R. rhabarbarum roots, which is equal to Gentamicin 10 µg.
S. aureus is known one of the common nosocomial infections in medical intensive care units [30].
Several researchers study antimicrobial activity of some plant extracts on S. aureus strains. For example, Nair
and Chanda [31] compared 10 medicinal plants antimicrobial effects on S. aureus strains, namely Anethum
gravelons, Commiphora wightii, Emblica officinalis, Ficus benghalensis, Ficus racemosa, Ficus religiosa,
Ficus tisela, Hibiscus cannabinus, Mentha arvensis and Mimusops elengi. In this study maximum activity of
ethanol extract was shown by E. officinalis with 9 mm of inhibition zone. In our study we observed 20 mm zone
for 25000 µg.µL-1
of R. rhabarbarum roots. Comparing these results clearly puts forward how R. rhabarbarum
roots are active against S. aureus when compared to some other higher plants.
IV. CONCLUSION
As a result, it can be concluded that there is clear antimicrobial activity of R. rhabarbarum roots
against all of the strains tested. The results of our study clearly presents that R. rhabarbarum roots could have a
possible medicinal uses especially against L. monocytogenes ATCC 7644, E. faecium, P. fluorescens P1, B.
subtilis DSMZ 1971, S. epidermidis DSMZ 20044 and P. aeruginosa DSMZ 50071.
But further researches are needed to be conducted in order to analyse the active substances and their
activity mechanisms in details.
