目的
2
探讨大豆异黄酮(SI)对幼鼠生殖发育的影响。
方法
2
将C57BL/6幼鼠随机分为对照组和SI小、大剂量组(10、100 mg/kg),每组10只,雌雄各半。各药物组幼鼠灌胃相应药液,每天1次,持续2周。末次灌胃后,计算幼鼠的体重增长百分比,检测血清雌二醇、睾酮水平以及生殖器官组织中丙二醛(MDA)含量、总抗氧化能力(T-AOC)和超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性,观察其生殖器官组织的病理改变,并检测其细胞凋亡情况。
结果
2
与对照组比较,SI大剂量组雌性幼鼠的体重增长百分比显著升高,而雄性幼鼠的体重增长百分比显著降低(
P
<0.05或
P
<0.01)。SI各剂量组幼鼠卵巢组织均可见囊性卵泡,睾丸组织可见精母细胞排列松散,附睾组织可见部分上皮细胞脱落。SI各剂量组雌性幼鼠血清睾酮水平和雄性幼鼠血清睾酮、雌二醇水平,SI小剂量组雌性幼鼠卵巢组织中GSH-Px活性和SI各剂量组雌性幼鼠卵巢组织中T-AOC,以及SI各剂量组雄性幼鼠睾丸及附睾组织细胞凋亡率均显著升高(
P
<0.05或
P
<0.01);SI各剂量组雌性幼鼠血清雌二醇水平,SI大剂量组雌性幼鼠卵巢组织中SOD活性和SI各剂量组雌性幼鼠卵巢组织中MDA含量,以及SI各剂量组雌性小鼠卵巢组织细胞凋亡率均显著降低(
P
<0.05或
P
<0.01)。
结论
2
SI可提高雌性幼鼠卵巢组织的抗氧化应激能力,减少其氧化应激损伤,但对雄性幼鼠的生殖器官具有一定的蓄积毒性。
OBJECTIVE
2
To investigate the effects of soybean isoflavones (SI) on the reproductive development of young mice.
METHODS
2
C57BL/6 young mice were randomly divided into control group, SI low-dose and high-dose groups (10, 100 mg/kg), with 10 mice in each group (half male and half female). The young mice in each group were given corresponding liquid intragastrically, once a day, for 2 consecutive weeks. After the last administration, the percentage of body weight increase was calculated; serum estradiol and testosterone levels, malondialdehyde (MDA) content, total antioxidant capacity (T-AOC), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in the reproductive organs of the young mice were determined. The histopathological changes in the reproductive organs were observed. The cell apoptosis of reproductive organs was detected.
RESULTS
2
Compared with the control group, the percentage of body weight increase in female mice was increased significantly in the SI high-dose group, while that of male mice was decreased significantly (
P
<0.05 or
P
<0.01). Cystic follicles could be seen in the ovarian tissue in SI groups, a loose arrangement of spermatocytes could be seen in the testicular tissue, and partial epithelial cell shedding could be seen in epididymal tissue. The serum level of testosterone in female young mice and the serum levels of testosterone and estradiol in male young mice in SI groups, GSH-Px activity in the ovarian tissue of female young mice in the SI low-dose group, T-AOC activities in the ovarian tissue of female young mice in SI groups as well as the apoptotic rates of cells in testicular and epididymal tissue of male young mice in SI groups were increased significantly (
P
<0.05 or
P
<0.01); the serum level of estradiol in female young mice in SI groups, SOD activity in the ovarian tissue of female young mice in the SI high-dose group, and MDA contents in the ovarian tissue of female young mice in SI groups as well as the apoptotic rates of cells in ovarian tissue of female mice in SI groups were decreased significantly (
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
SI can enhance the antioxidant stress capacity of ovarian tissue in female young mice and reduce their oxidative stress damage, but it has certain toxicity to reproductive organs in male mice.
