Resumo: 	Objective: We tried to explore beneficial effects of allicin- a natural antioxidant from garlic in the possible management of vaginitis. &amp;#xd;&amp;#xa;Methods: Peripheral blood mononuclear cells (PBMC&amp;#x2019;s) were isolated from blood of patients having vaginal infections as well as normal healthy subjects as per our published protocol. Monocytes (MN&amp;#x2019;s) from above PBMC&amp;#x2019;s were adhered, rested overnight and cultured without or with varying doses of allicin (0-500 ng/ml). Some cultures received SN50 and SN50M (100 ug/ml). After 24 hrs cultures, the cells were harvested and the supernatants subjected to secreted TNF-&amp;#x3b1; and sIFN-&amp;#x3b3; assays by ELISA. Treated/untreated harvested cells were subjected to glutathione peroxidase (GPx) activity assay.&amp;#xd;&amp;#xa;Results: We show involvement of inflammatory cytokines and reactive oxygen species (ROS) in vaginitis. Augmented secreted TNF-&amp;#x3b1; and decreased sIFN-&amp;#x3b3; levels were observed in monocyte cultures of vaginal patients. Relative to healthy controls, a decrease by 2.5-fold in glutathione peroxidase (GPx) activity in cultures of vaginal patients was observed. Treatment with allicin from garlic appreciably decreased secreted TNF-&amp;#x3b1; with simultaneous amelioration in sIFN-&amp;#x3b3; and GPx activity. Allicin (500 ng/ml) ameliorated GPx activity by ~ 2.16-folds in patient monocyte cultures. The anti-oxidant and anti-inflammatory actions of allicin induced in monocyte cultures of vaginal infection patients were mediated via NF-&amp;#x3ba;B.&amp;#xd;&amp;#xa;Conclusion: Thus, the above results may help in understanding the use of allicin as an adjunct in vaginal infection therapy, and in turn, may address the globally female health.&amp;#xd;&amp;#xa;
