The effects of Chamomile tea on antioxidative biomarkers in operating room staff

Introduction: Chamomile tea (CT) is an herbal tea and is served as a beneficial herbal infusion all over the world. Its major polyphenols constituents and tea-catechins have been shown to have health benefits. Operating room staff are commonly exposed to damaging factors, such as radiation, waste anesthetic gases and psychological stress. One of the most important qualities of CT is its antioxidant property. The aim of this study was to evaluate the effects of CT in reducing the oxidative stress of operative room staff that are chronically exposed to damaging factors. Methods: In this study we approached to 20 operating room personnel. The subjects drank 2 cups of CT (every cup contained 1.8730 g of chamomile and 300 ml of water) daily, one cup in the morning and another in the afternoon for 21 days. A questionnaire that contained personal information was filled by each subject. Oxidative stress parameters such as total antioxidant capacity (TAC), catalase (CAT) and total thiol molecules (TTG) were measured 2 times: first before drinking CT at the first day and the next time after the 21st day. Results: Consumption of CT by subjects caused a significant induction in TAC (6.62 &plusmn; 0.77 vs 4.81&plusmn; 0.39 ųmol/ml, P &lt; .05) of saliva. There was not any statistically significant change in saliva TTG and CAT after 21 days of drinking CT. Conclusion: In the end we came to conclusion that CT can be a useful additional food to remove the oxidative damage that happens to operating room staff.</p

Antioxidativeand hepatoprotective effects of Artemisia absinthium L. hydroalcholic extractin rat

Introduction: Artemisia absinthium L. (AA) is a large, diverse genus of the family Asteraceae. AAhas long been used as customary herbal medicine in world for the treatment of gastric pain, cardiacstimulation, improvement of memory and for the restoration of declined mental function. The aimof present study was to evaluate the hepatoprotective effects of AA on some factors ref lecting thedevelopment of oxidative toxic stress in plasma.Methods: Twenty male rats were equally divided in to 4 groups (5 rats each). Group I actedas control (received normal salin). Treatment groups were II, III and IV which were givenArtemisia 10, 50 and 100 mg/kg/day respectively only by gavage for 24 hours. After treatment,blood specimens were collected. Liver enzymes such as aspartate aminotransferase (AST) andalanine aminotransferase (ALT) with total antioxidant power (TAP) and total thiol groups (TTG)concentrations were measured.Results: Levels of ALT, AST and TTG were decreased in the group II compared to the control(group I). ALT and AST in 50 mg/kg group was observed compared with control group. Also, TTGincreased in Artemisia 50 mg/kg group compared to control group.Conclusion: Results suggests that alcoholic extract of Artemisia can ameliorate liver toxicity inrats through reducing the serum levels of ALT, AST, and oxidative damage

Protective role of green tea on malathion-induced testicular oxidative damage in rats

Objective: To examine effects of total green tea extract, a potent free radical scavenger on testicular tissue oxidative status. Methods: 32 male albino rats of Wistar strain were divided into four groups, every group restricted 8 animals: (i) control rats; (ii) green tea-treated control rats; (iii) malathion rats; (iv) malathion-treated green tea rats. Animals received malathion 150 mg/kg and green tea 30 mg/kg for 24 h intraperitoneally. At the end of the treatment period, rat testis tissues were quickly removed and analyzed. Diameter of seminiferous tubules and germinal cell thickness, spermatogonia sertoli cells, primary spermatocytes, spermatids and leydig cell were evaluated. Also, oxidative stress evaluation was conducted based on total antioxidant capacity (TAC), lipid peroxidation (LPO) and total thiol molecules (TTM) in homogenate testis tissues. Results: The results showed that total green tea extract improve oxidative damages against malathion group. Light photomicrograph of seminiferous tubules in malathion-treated group showed noticeable reduced height of germinal epithelium and disorganization of the tubules. An increased intestinal tissue was also observed. Primary spermatocytes were located distance from basal lamina indicating it induced damages to the intestinal tissue. While seminiferous tubules in malathion exposed and green tea extract-treated were normal. Conclusion: This study demonstrated the effectiveness of TGTE on oxidative stress and testicular tissue damage induced in malathion in infertility disorders
