黄酮和维生素E对己烯雌酚所致雄性小鼠肝脏氧化损伤的保护作用 总被引:1,自引:1,他引:0
The purpose of this study was to investigate the oxidative damage caused by different doses of diethylstilbestrol (DES) and the protective effects for DES induced toxicity with flavonoids and vitamin E in Kunming mice. 80 Kunming male mice were randomly divided into 10 groups, the groups were normal saline control group, DES exposed groups (0.035, 0.35, 3.5 mg/(kg穌)), flavonoids interference groups(26.0, 58.0, 112.0 mg/(kg穌)) and vitamin E interference groups(56.2, 112.4, 224.8 mg/(kg穌)). The effects on liver and testis were studied in adult male mice treated for one week. Mice were killed to collect liver and testis, and then contents of malonadehyde (MDA), superoxide dismutase (SOD), glutathione perxidase (GSH-Px) and total antioxidant capacity (T-AOC) were determined. It was found that high dose DES (3.5 mg/(kg穌)) could induce mice liver oxidative injury. The protective effects of flavonoids for DES induced toxicity on liver dose dependent increased. The contents of MDA significantly decreased (P<0.01), but the contents of SOD significantly increased in the high dose group (112 mg/(kg穌)). The contents of MDA significantly decreased (P<0.01), but the contents of GSH-Px, SOD and T-AOC significantly increased in the medium and high dose groups (112.4, 224.8 mg/(kg穌)). DES appeared to cause oxidative injury in Kunming mice. The results provided preliminary experimental support for flavonoids and vitamin E as medicine for DES induces damage. 相似文献

采用高效液相色谱法,研究在单次口灌给药途径下,恩诺沙星在杂交鲟(施氏鲟Acipenser schrenckii♂×达氏鳇Huso dauricus♀)体内的药代动力学。对杂交鲟单次口灌给药恩诺沙星10 mg/kg后,用3P97药代动力学分析软件对实验数据进行了分析。结果表明:恩诺沙星在杂交鲟血液、肌肉和肝脏中的药物时量曲线关系符合一级吸收的二室开放模型;该药在血液、肌肉和组织中的平均回收率分别为93.6%±1.14%、92.65%±1.5%、92.82%±1.39%,在杂交鲟不同组织中分布较广,其在血液、肌肉和肝脏的表观分布容积v/f分别为26.987、6.2298、2.1515 L/kg;恩诺沙星在杂交鲟体内消除较慢,在血液、肌肉和肝脏中的消除半衰期分别为290.139、114.9、901.835 h,总体清除率分别为0.2288、0.1047、0.02164 L/(kg.h)。鉴于恩诺沙星在杂交鲟体内消除较慢,建议养成阶段使用其它药物。 相似文献
