砷中毒大鼠生精细胞凋亡的变化

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2009
【目的】 观察不同剂量的三氧化二砷(As2O3)对成年大鼠生精细胞凋亡的影响65377; 【方法】 40只健康雄性SD大鼠随机分成对照组65380;低剂量组(0.0375 g/L)65380;中剂量组(0.075 g/L)65380;高剂量组(0.15 g/L) 4组,灌胃法连续给药16周后对各组大鼠睾丸取材进行精子头计数,并计算睾丸脏器系数65380;每日精子生成量(DSP)65377;采用甲基绿-派诺宁染色法和TUNEL法检测大鼠生精细胞凋亡情况65377; 【结果】 ① 中65380 ...

内、外源性性激素对大鼠实验性十二指肠溃疡形成的影响

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1989
雌鼠较雄鼠有较强的抗实验性十二指肠溃疡(DU)形成的能力,卵巢摘除后这种能力减弱,睾丸摘除对DU形成无影响。戊酸雌二醇和孕酮也有抗雄鼠DU形成的作用,而丙酸皋酮则无此作用。雌鼠血清胃泌素水平和胃酸分泌均低于雄鼠,卵巢摘除后血清胃泌素水平和胃酸分泌均明显升高。睾丸摘除对雄鼠血清胃泌素水平和胃酸分泌无影响。戊酸雌二醇可减少雄鼠血清胃泌素水平和胃酸分泌,而丙酸睾酮则无此作用。本实验结果可部分解释女性DU发病率明显低于男性。抑制胃泌素和胃酸分泌作用,可能是戊酸雌二醇抗DU形成机制之一。
