以3周龄C57BL/6小鼠为研究对象,分析大豆异黄酮(soybean isoflavones,SI)处理后肝肾组织形态、抗氧化和凋亡情况,探讨SI对幼年小鼠肝、肾发育的影响.结果表明,随着SI剂量的增加,雌性小鼠体重增长百分比呈增加趋势(P<0.05),雄性小鼠体重增长百分比呈减少趋势(P<0.01).对雌性小鼠,SI处理提高了肝脏和肾脏的抗氧化损伤能力(P<0.05),减轻了肝脏和肾脏的组织损伤;对雄性小鼠,SI处理降低了肝脏抗氧化损伤的能力(P<0.01),但增加了肾脏抗氧化损伤能力(P<0.05);肝脏发生了病理性损伤,肾脏无组织损伤.研究结果提示幼年雄性个体摄入SI剂量需谨慎.
Effects of soybean isoflavones on the tissue structure and antioxidant activity of liver and kidney in young mice
The 3-week-old C57BL/6 mice were treated with soybean isoflavones(SI).The morphology,antioxidant capacity and apoptosis of liver and kidney tissues were investigated,and the effects of SI on liver and kidney development in young mice were explored.The results showed that the percentage of body weight increasing in female mice is increased in a dose of SI dependent manner(P<0.05),while male mice is decreased(P<0.01).In female mice,SI treatment increases the antioxidant ability of liver and kidney(P<0.05),and reduces the tissue damage of liver and kidney.In male mice,SI treatments decrease the antioxidant ability of liver(P<0.01),but increase the antioxidant ability of kidney(P<0.05).There is pathological damage to the liver,and no tissue damage to the kidney.It is suggested that young males should be cautious taking SI.
