The results showed that TNF-α effectively inhibited preadipocyte proliferation stimulated by insulin and decreased lipogenesis through inhibiting stimulation of insulin on transcriptional expressions of lipogenic genes such as acetyl-CoA carboxylase α(ACC1), fatty acid synthase, sterol regulatory element binding protein-1c in adipocytes, suggesting that TNF-α is a effective inhibitor of adipogenesis in adipose tissue.

结果表明，TNF-α可有效抑制胰岛素对原代培养大鼠前体脂肪细胞增殖的促进作用，并通过抑制胰岛素对转录因子SREBP-1c和脂肪酸合酶FAS及ACC1基因转录表达的促进作用，减少脂肪酸的生物合成，抑制成熟脂肪细胞的脂肪生成，证明TNF-α是动物脂肪形成的有效抑制因子。

Each group of rats was kept in a separate cage. All of the rats drank water freely and were fed on stand food for rats.The experiment lasted 4 weeks. Indexes to be examined are as follows:⑴spleen T lymphocyte transform value,⑵spleen NK cell activation alternation value,⑶abdominal cavity macrophagocyte IL-1 and IL-2 activation alternation value.

At 4-week, GAG content in JG as significantly lower than that in RG and CG, while dead cell ratio in RG significantly higher than those in JG and CG. Mankin scores in RG and JG ere significantly higher than that in CG. At 8-week, GAG content in RG as significantly lower than that in CG, while dead cell ratio and Mankin scores ere significantly higher than those in CG.

结果 显微观察显示两组训练动物在训练4周时便开始有膝关节软骨过劳性损伤早期改变，8周时损伤改变进一步加重。4周时，蹦跳组GAG含量明显低于对照组及跑步组，跑步组死亡细胞率明显高于对照组以及蹦跳组，跑步组和蹦跳组Mankin评分明显高于对照组；8周时，跑步组GAG含量明显低于对照组，死亡细胞率与Mankin评分明显高于对照组。

In addition, the journal publishes key papers on chromosome aberrations in somatic, meiotic and malignant cells of man and other animals.

Methods The nitroglycerin experimental migrainous animal model was reconstructed for the expression of c-fos and c-jun by means of immunohistochemical method Results The nitroglycerin experimental migrainous rats appeared reddish two ears, head shaking,scratching head with forepaws, activity increasing, both the number increasing and the area enlarging of the positive cells of the expression of c-...

免疫组化ABC法研究偏头痛大鼠脑组织即刻早期基因c -fos、c -jun的表达。结果硝酸甘油型实验性偏头痛大鼠出现双耳发红、甩头、前肢频繁搔头，活动增加等外在表现，脑组织c -fos、c -jun基因表达阳性细胞数增加，基因表达阳性细胞的面积扩大、灰度降低或变化不大。结论硝酸甘油型实验偏头痛大鼠模型复制方法简单、重复性较好、脑组织c -fos和c -jun基因异常表达明显，可以作为偏头痛治疗药物筛选、药效评价和发病机理研究的动物模型。

Form PLA is a nonvirulent macromolecular compound with biocompatibility, which used in the manufacture of new biodegradable plastics, fiber, and biomedical material.

型乳酸，分子式C3H6O3，为含有氢氧基的有机酸，是生物的代谢中间产物。L型乳酸可以在动物和人类细胞中新陈代谢因为这些细胞含有L型乳酸去氢酵素。L型乳酸还可用於生产L型乳酸聚合物。L型乳酸聚合物属於无毒的高分子化合物，具有生物相容性，可用於制造生物可分解的塑胶、纤维以及生医材料等。

The left external jugular vein of 20 rabbits were harvested and transplanted between ipsolateral common carotid artery. Three days later, animals in group Ⅰ were transplanted with BMMNCs (6×10^8 cells)/100 μl via periotic veins and those in group Ⅱ were injected with 100 μl PBS.

取左颈外静脉4~5cm，上下倒置后移植至颈总动脉，在建模后第3天将100μl DAPI标记的BMMNCs液（6×10^8个细胞）经耳缘静脉注入细胞移植组动物体内，对照组注入等量的PBS液。

The giant panda-rabbit interspecies reconstructed embryos were constructed by injection of giant panda somatic cells into the perivitelline space of the enucleated oocytes and fused by electrical stimulation, and the reconstructed embryos can develop to hatched blastocyst stage in vitro. We demonstrated that the nuclear genetic materials in reconstructed blastocyst cells were the same as that of giant panda somatic cells by chromosome count and the existence of characteristic chromosome, which was confirmed by microsatellite DNA analysis later In order to determine the fate of mtDNA of giant panda-rabbit reconstructed embryos, we analyzed the cyt b sequence of embryos at 1 -cell stage, 2-cell stage, 4-cell stage, 8 cell stage, morula stage, blastocyst stage, expanded blastocyst stage and hatched blastocyst stage.

异种克隆大熊猫重构胚是通过将大熊猫成纤维细胞移入日本大耳白兔去核卵母细胞透明带下后经电融合构建的，可在体外发育至孵化囊胚阶段，我们应用一种简便、快速的异种重构胚的鉴定方法，即通过染色体数目和特征染色体的存在初步鉴定出大熊猫-兔异种重构胚的核遗传物质来源于大熊猫供核体细胞（后经昆明动物研究所通过微卫星DNA分析验证了该结果的可靠性）。
