7 epoxide-containing compounds: allylbenzene oxide, styrene oxide, trans-beta-methylstyrene oxide, 4-chlorophenyl glycidyl ether, vinylcyclohexene dioxide, octene dioxide and hexene dioxide were evaluated for mutagenic activity in 4 histidine-requiring strains of Salmonella typhimurium, namely: TA1535, TA100, TA1537 and TA98. These epoxides, except trans-beta-methylstyrene oxide, were mutagenic...
Recent studies have suggested that nitric oxide (NO.), the product of nitric oxide synthase in inflammatory cells, may play a part in tissue injury and inflammation through its oxidative metabolism. In this study the colonic generation of oxides of nitrogen (NOx) and nitric oxide synthase activity was determined in ulcerative colitis and Crohn's disease. Colonic biopsy specimens were obtained f...
Estrogen-induced apoptosis has become a successful treatment for postmenopausal metastatic, estrogen receptor-positive breast cancer. Nitric oxide involvement in the response to this endocrine treatment and its influence upon estrogen receptor-positive breast cancer progression is still unclear. Nitric oxide impact on the MCF7 breast cancer line, before and after estrogen-induced apoptosis, was...
Antioxidant activity of chloroform extract of Aesculus indica leaves was investigated for its free radical scavenging activity by determining the nitric oxide and superoxide radical scavenging activity. Maximum scavenging of nitric oxide and superoxide radical found were 27.62% and 48.65% respectively at 250 μg/ml concentration.
