Their relative molecular weights were 4785 and 4386 respectively. And their absorbance peaks were 210.5 nm and 225.4 nm respectively. The bovine and caprine placental peptides could improve immunosuppressive T lymphocyte transformation rate. The immunosuppressive lymphocyte transformation rates in groups with the bovine placental peptide of 1:1×10^3 and 1:1×10^4 (P.05)and with the caprine placental peptides of 1:1×10^2, 1:1×10^3 and 1:1×10^4 (P.01 )increased more remarkably than that in immunosuppression group.

结果 从牛和羊胎盘中成功提取出了胎盘肽，其相对分子质量分别为4785和4386；其最大吸收峰分别为210.5和225.4nm；牛和羊胎盘肽均可使顺铂抑制的兔外周血T淋巴细胞的转化率显著提高，其中牛胎盘肽以1：l×10^3、1：l×10^4 2组吸收度明显高于抑制组(P.05)；羊胎盘肽以1：1×10^2、1：1×10^3和1：1×10^3 3组效果最为明显(P.01)。

The new GV preparation method we developed allowed the best visualization of chromatin distribution after Hoechst or CMA3 staining. Our results showed that GV chromatin configurations are different among different species, and thus, while chromatin condensed into a ring around the nucleolus in porcine and bovine oocytes, no such a ring was observed in caprine oocytes; Porcine oocytes were synchronized at GV1, goat oocytes at GV3n and bovine oocytes at GVf configurations before GVBD occurred, indicating that these configurations are progressive towards final maturation rather than atresia; Changes of chromatin configurations were associated with gene activity of transcription; GV chromatin configurations were affected by the environmental changes such as serum starvation and elevated temperature.

应用该技术对猪、山羊和牛不同大小、不同健康程度卵泡及体内和体外成熟过程中卵母细胞染色质构型的变化发现：1）不同动物卵母细胞染色质构型不同；猪和牛卵母细胞染色质围绕核仁凝集形成环，但山羊卵则没有此环。2）卵母细胞在GVBD之前都同步在某一染色质构型；猪同步在GV1，山羊GV3n，牛GVf，说明这些染色质构型代表着进行性变化。3）染色质构型的变化反映基因转录活动的变化。4）染色质构型受环境变化的影响。

The thickness of bovine liver in vitro ranged from 4 to 10 cm. Ultrasound energy was continuously delivered to ablate the liver with a frequency of 1.6MHz, and spatial peak pulse average acoustic intensity of 12000 W/cm^2. The characteristics of complete coagulation necrosis and exposure time were measured after FUSC exposure, and pathological changes in treated bovine liver tissue were observed.

Depending on the above research, it can be said that it has been provided experimental basic for the further research in the middling experiment of extracting the active component from the mixed bovine and ovine bile, supplied the reliable theory and possibility for comprehensive delevoping utilizing the bovine and ovine bile, and illustrated the distribution variation law of glycocholic acid in the blood-serum and texture of rat which is regarded to helping developing the biocherical drug from animal organs.

旨在为下一步开展从牛羊混合胆汁中提取有效成分的中试实验研究奠定试验基础，为牛羊胆汁的综合开发利用提供可靠的理论依据和可能性，同时为阐明甘氨胆酸在大鼠血清及组织中的分布和变化规律，开发脏器生化药物新资源提供线索。

The properties of several rhodopsin sequences were analyzed by comparing withα2A-adrenergic receptor, and a great similarity was found between bovine rhodopsin andα2A-adrenergic receptor. Therefore transmembrane helices ofα2A-adrenergic receptor were constructed homologically based on the bovine rhodopsin.In the newly constructed structure, a 0.090 nm3 active-site, which was enclosed by several reported active residues, was found.
