查询词典 minimum density

Methods seventy-two 15-week-old sd rats were divided into six groups,included control group and five ovariectomized model groups.the model groups were fed with different-dose lycopene［10,15,20 mg/］ for 12weeks.then related indexes including length bone mineral density,bone mineral,serum estradiol,sertum alp and uterus index were analyzed.results compared with model group,three different dose groups and nilestriol［1.05mg/］ group showed increased bone mineral density,bone mineral,serum estradiol and uterus index,but decreased serum alp (p.05).conclusion as a female sex hormone-like component,lycopene may ameliorate the bone quality and inhibit osteoporosis in ovariectomized rat.

将72只15周龄sd大鼠随机分为6组，空白组做假手术，其余5组做卵巢切除术，术后用药12周后处死，测定右侧股骨骨密度、骨矿含量、血清雌二醇、碱性磷酸酶含量及子宫湿重。结果番茄红素高［20mg/］、中［15mg/］、低剂量组［10mg/］、尼尔雌醇组［1.05mg/kg·bw］能对抗骨密度、骨矿含量、血清雌二醇的下降、血清碱性磷酸酶的升高，与模型组比较，p.05；番茄红素各剂量组、尼尔雌醇组能对抗子宫指数的减轻，与模型组比较，p.05。结论番茄红素可以改善骨质量，抑制大鼠去卵巢骨质疏松的发生。具有类似雌激素的效应。
