ABSTRACT
Objective: Tea is a widely consumed beverage worldwide. The effect of green tea is mainly due to its high polyphenols-(-) epigallocatechin-3-gallate (EGCG) content in the culture of cancer cell and bacterial cells. The present work was carried out to investigate the efficacy of green tea oil (GTO) against cancer cells and bacterial cells. Methods: In this study green tea oil was prepared from green tea for different experiment and determination of fatty acids profile from green tea oil. In the present study, peripheral blood lymphocyte (PBL) was chosen as human peripheral blood lymphocytes and blood cancer MCF-7 cells were chosen as human cancer cells. To fulfill our aims and also to evaluate the activity of this phytomedicine against normal lymphocytes and cancer cells the cell samples were divided into 26 experimental groups in the following ways. Each Petri dish contains 2 X 105 cells. Results: GTO shows a potent anticancer agent but nontoxic to normal cells. The GTO decreases the reduced glutathione (GSH) level and increase the oxidized glutathione (GSSG) level significantly (P<0.05) in MCF-7 cells. But in lymphocytes the GSH level and GSSG level were almost the same with the control group but doxorubicin (DOX) significantly decreased the GSH and increase the GSSG level. Green tea oil treatment causes generation of reactive oxygen species (ROS) in MCF-7 cells revealed by DCFH2DA staining. Agar diffusion test shows the GTO is effective against multi-drug resistant bacteria. Conclusion: This phytomedicine has a potent anticancer activity without damaging the normal lymphocytes. So, this drug can be used for further treatment of anticancer and antibacterial.
ABSTRACT
BACKGROUND: Leptospirosis, a zoonosis, is a re-emerging disease, affecting populations across the globe. However, the current methods of diagnosis are time- consuming, cumbersome, imprecise or expensive. AIM: To develop an assay for differential and early diagnosis of Leptospirosis. METHODS AND MATERIAL: IgG based ELISA for evaluation of three antigens, namely, a gel-purified recombinant protein (rLipL32), secreted proteins and whole organism sonicates of Leptospira spp. The antigens were evaluated using, rabbit polyclonal antiserum and human sera samples. RESULTS: Studies with a rabbit polyclonal antiserum indicated the utility of these antigens in differentiating Leptospira from other common pathogenic organisms. Evaluation of these antigens with fifteen representative human serum samples indicated gel-purified rLipL32 to be a potentially useful antigen for detection of leptospirosis. The results obtained with IgG ELISA were correlated with the results of microscopic agglutination test (MAT). CONCLUSION: Gel-purified rLipL32 is a valuable antigen for early and accurate diagnosis of leptospirosis. Further evaluation of this assay in field conditions and larger sera samples will indicate its suitability in case of an epidemic.

Injection of lithium chloride at the dose of 200 micrograms/toad/alternate day for 7, 14 and 21 days caused a significant reduction in the activities of testicular delta 5-3 beta, 17 beta-hydroxysteroid dehydrogenase and acid phosphatase enzymes. There was a marked inhibition in spermatogenesis in lithium chloride treated toad for 14 and 21 days of treatment, but 7 days of treatment has no effect.

A case of pulmonary hydatid disease which ruptured to produce a hydropneumothorax is reported. Radiologically the patient presented with an oval opacity which enlarged with an appearance of air crescent. Diagnosis was established by cytological examination of aspirated pleural fluid and an histopathological examination of tissue found in the drainage tube. The patient was managed conservatively with intercostal drainage, albendazole therapy and other supportive measures.

In a prospective study of 124 neonates born to mothers with normal pregnancy and pregnancy associated hypertension (PAH), serum IgG, IgA and IgM were estimated by single radial immunodiffusion technique. Significantly low levels of IgG were found in mothers having PAH, as compared to normal pregnancy (p less than 0.001), whereas IgA and IgM showed no difference in the two groups. There was no statistical difference in maternal and cord blood IgG in either the control or study group. IgG was significantly higher (p less than 0.001) in cord blood of babies born by vaginal route as compared to forceps (via vaginal route) or cesarean section. IgA and IgM levels did not vary with mode of delivery.
