ABSTRACT
The study was conducted to elucidate the genotoxic effect of deltamethrin in Swiss Albino male mice following oral exposure, by comet assay and micronuclei induction test. Deltamethrin was administered at the dose rate of 1.5 mg/kg bwt, 1.0 mg/kg bwt and 0.5 mg/kg body weight. Mean head DNA percentage, mean tail DNA percentage, mean tail length and mean olive moment were the endpoints for the comet assay. Deltamethrin resulted in a significant comet formation at 15, 30 and 60 days of oral exposure in a dose and time dependent manner. Mean tail DNA% at 15, 30 and 60 days of exposure to deltamethrin was 59.28, 57.74 and 63.14, respectively. The results were found to be significantly different in treatment groups as compared to the control groups. Micronucleated normochromatic erythrocytes, micronucleated polychromatic erythrocytes and polychromatic erythrocytes percentage were the endpoints for the micronuclei induction test. Deltamethrin induced significantly higher number of micronuclei in treatment group than the negative control. In conclusion, present study indicates that pesticides are slow poison and even a low dose of pesticide can cause genotoxicity and other biological effects when exposed to for longer duration.
ABSTRACT
In economically developing countries, the global burden of cancer persists to increase chiefly because of the aging and growth of the world population along with an increasing implementation of cancercausing behaviors, particularly smoking, physical inactivity and fast food. Cancer group accounts approximately 13% of all deaths each year with the most common being: lung cancer (1.3 million deaths), stomach cancer (803,000 deaths), colorectal cancer (639,000 deaths), liver cancer (610,000 deaths), and breast cancer (519,000 deaths). In India, the rate of oral, oesophagus and cervical cancers are some highest in the world according to 2011 Statistics. Various treatments are used to cure some cancers, but the battle against this disease is ongoing. The source of biologically active compounds originally isolated from plants. These natural compounds can acts as anti cancerous agents. Hence, the current study focuses on the use of 15 different natural products in the treatment of cancer.
