ABSTRACT
Objective To study the effects of siritch vapor condensate (SVC) on lipid peroxidation of mice and its mutagenicity to mice. Methods 60 healthy Kunming mice were selected and randomly divided into 6 dose groups, 10 mice per group: SVC high_dose group (10 ml/kg), SVC middle_dose group (5 ml/kg),SVC low_dose group (2.5 ml/kg), prepared siritch control group, negative control group (tap water) and positive control group (cyclophosphamide, 50 ml/kg). Except the positive control group treated by peritoneal injection with cyclophosphamide 50 ml/kg for 3 times, the other 5 groups were treated by oral perfusion with different doses of SVC, prepared siritch and tap water once a day for 15 days. After exposure, the contents of malonyldialdehyde (MDA) and the activities of superoxidide dismutase (SOD) in plasma were determined, the frequency of micronuclei in bone marrow cells and counts of abnormal morphologic sperm were observed and analyzed in mice. Results The significantly higher contents of MDA and lower activities of SOD were observed in SVC 10 ml/kg, 5 ml/kg, 2.5 ml/kg and prepared siritch control groups compared with those in negative control group respectively (P
