摘要: 研究生、制首乌正己烷提取物对维甲酸致小鼠骨质疏松的防治作用,并探讨其主要作用机制。采用维甲酸(105 mg·kg-1)致小鼠骨质疏松模型,生首乌正己烷提取物高、低剂量组48、24 mg·kg-1,清蒸制首乌正己烷提取物高、低剂量组48、24 mg·kg-1,黑豆制何首乌正己烷提取物高、低剂量组48、24 mg·kg-1,灌胃给药,2周后以比色法测定血清钙、磷含量和碱性磷酸酶(ALP)、抗酒石酸酸性磷酸酶(TRAP)活性,竞争放射免疫法测定血清中骨钙素(BGP)和雌二醇(E2)含量,取股骨进行骨组织形态学观察。结果表明:维甲酸可引起高转换型骨质疏松,与模型组比较,生、制首乌各剂量组可显著升高s-E2的水平(P<0.05),降低s-ALP、s-TRAP和s-BGP的水平(P<0.05,P<0.01);生、制首乌各组与模型组比较,骨组织形态均有不同程度的改善,骨小梁数明显增加。从以上结果可知,生、制首乌正己烷提取物对维甲酸致小鼠骨质疏松有明显的治疗作用,其机制可能与减缓雌激素水平降低,抑制骨高转换有关。

Abstract: We investigated the anti-osteoporosis effect and the possible mechanism of PM-HE (Hexane extract from Raw and Processed Polygonum multiflorum) in animal model.Kunming mice were randomly divided into 9 groups:Control group (normal saline),model group,nilestriol group (2 mg/kg),PM-HE groups (48,24 mg/kg).The mice osteoporosis was induced by given retinoic acid intragastrically.After oral administration for 14 days,the features of bones and biochemicals in serum were determined to evaluate the anti-osteoporosis effects of PM-HE .The results showed:PM-HE can induce high conversion of osteoporosis.The levels of ALP,TRAP and BGP in the PM-HE groups were lower than those in the model group (P<0.05,P<0.01),whereas the E2 level was higher than that of the model group (P<0.05).PM-HE can prevent the loss bone in the experimental mice.The mechanism may be the inhibition of estrogen decrease and the high bone turnover.
