ABSTRACT
Possible effects of physical and chemical environmental pollutants in modern industrial life on human health concern about one of the largest problems for scientific organization and the government. About 60 newest published articles results have been studied in last decade [2002-2013] in this research about inhibitory effects of green tea on electromagnetic waves damages. Then we have been used about 40 of them in this review article. For this aim, we searched some key words such as environmental damages, electromagnetic waves, antioxidant effects and anticancer effects of green tea in Science Direct, Springer and Elsevier. Nowadays, scientists' effort to use natural ingredient instead of drugs and chemicals to maintain human health more and prevention of diseases. Among such, consumption of green tea has the longest history in the world and now in over 160 countries around the world as the common beverage is consumed daily. Recently, green tea due to its numerous benefits in health, in prevention and in treatment of diseases such as cancer has been considered in the public opinion and in the scientific community. Because of its application, in addition to traditional methods of brewing has prevalence as a natural ingredient in food or feed products and in the pharmaceutical and cosmetics industries
ABSTRACT
Green tea [Camellia sinensis] extract is rich source of natural antioxidants specially catechin that is quickly absorbed into the body and it has cancer protective, anti microbial and anti inflammation effects. In this study has been studied role of green tea extract against genotoxic damage induced by cell phone microwaves on bone marrow polychromatic erythrocytes of adult male Balb/C mouse. In this experimental study 40 mouse were divided into five groups, control animals were located under natural condition, sham -exposed animals were prepared by experimental condition without cell phone waves radiation. Experimental 1 group that irradiated at cell phones for 4 days [3 hours/day] and experimental 2 group were injected intraperitoneal 100 mg/kg green tea extract for 5 days and experimental 3 group that irradiated at active mobile phones for 4 days [3 hours/day] and were injected intraperitoneal 100 mg/kg green tea extract for 5 days. After treatment period micronucleus test was evaluated in polychromatic erythrocytes on bone marrow. The quantitative data was analyzed by ANOVA and Tukey test with using of SPSS-13 software at the level of p<0.05. Based on this study, treatment with extracts of green tea decreased micronucleus frequency in bone marrow polychromatic erythrocytes of Balb/C mouse that irradiated at cell phone microwave [0.92 +/- 0.129], [p<0.001]. Cell phone microwaves [940 MHz] increased micronucleus on bone marrow polychromatic erythrocytes of male Balb/C mouse, but green tea had inhibitory effect and it decreased the average number of micronucleus
