Methods Six weeks old male Fischer 344 rats (F344) were used as donors, and six weeks old male F344alb as recipients. All F344alb were divided into 4 groups: group Ⅰ(n=10) was untreated; group Ⅱ(n=10) was treated with CCl4 but no γ-irradiation and transplantation; group Ⅲ(n=10) was transplanted with 1×10^7 BMCs after γ-irradiation, but without CCl4 treatment; group Ⅳ(n=10) was transplanted with 1×10^7 BMCs after γ-irradiation, with CCl4 treatment. The BMCs prepared from the donors were infused via the penial veins of recipients immediately after whole body γ-irradiation (7.5Gy) and CCl4 treatment: 4 weeks after BMCs transplantation, CCl4 were injected into peritoneal cavity twice a week for 4 weeks.

雄性F344大鼠为供体，而雄性F344alb为受体，分为4组：组Ⅰ(n=10)为正常对照组，不接受肝损处理，无全身射线照射和阴茎静脉骨髓细胞移植；组Ⅱ(n=10)为肝损无移植组，只接受肝损处理，无全身射线照射和阴茎静脉骨髓细胞移植；组Ⅲ(n=10)为正常移植组，全身射线照射后阴茎静脉移植骨髓细胞1×10^7；组Ⅳ(n=10)为肝损移植组，接受CCl4注射肝损，全身射线照射后阴茎静脉骨髓细胞移植1×10^7BMCs，其中，γ-照射剂量为7.5Gy，F344大鼠的BMCs经受体的阴茎静脉注入。

The results showed that male body size did not affect sexual preference among female croaking gouramis.

Methods "Beiao" bait and no "beiao" were selected to evaluate the feeding acceptability of SD rats in laboratory by select fooding method;after putting "beiao" in field for three and six monthes,the results for controlling rats by trap were recorded respectively;rats procreation and rate of infancy and manhood of catching rats from three fields("beiao" bait,Anti Cruor bait and naturalness) were analized by anatomised.

方法实验室采用常规毒饵适口性实验方法观察适口性，现场选择在农田、农户环境，于4次投放毒饵后检查鼠类对贝奥雄性不育剂的消耗水平，用贝奥雄性不育剂处理后3个月和6个月测定鼠密度，解剖观察成年鼠生殖能力，测量成幼年鼠的比例。
