Objective It was reported that rALR (rat augmenter of liver regeneration) distribute in most of tissue and organ of rat, no-tissue specility; mRNA expression of rALR was identified variedly in different tissue, strongest in testis. But nowadays there was not some study on ALR in rat testis. Here to confirm the expression and localization of ALR in infancy,adult and old rat testis,comparing the change of ALR expression degree before per 70 PH and after per 70 PH. In order to evaluate expression principle of ALR in rat testis and know if ALR has tight connection with spermatogenesis and development of testis, to explore the relation between ALR and reproduction, to discover the possible expression character and functional methods of ALR.

目的：文献报道rALR分布于各组织器官，无组织特异性，但其mRNA在各组织的表达强度有差异，在睾丸组织表达最强，目前对大鼠睾丸ALR表达尚无深入的研究；本实验研究不同年龄段大鼠睾丸组织中肝再生增强因子的表达水平、表达部位、以及表达的方式，进而探讨睾丸ALR与睾丸发育、精子生成以及生殖活动的关系；同时探究睾丸组织ALR表达是否参与了肝脏的再生过程中，进一步了解睾丸ALR表达的特性及作用方式。

MethodsNonheparinized autohemic blood of the rat was taken out from rat"s femoral artery and injected into its caudate nucleus immediately to establish a model of intracerebral hemorrhage.The changes of edema in the ipsilateral bassal ganglia , ipsilateral cortex, contralateral bassal ganglia and contralateral cortex were measured at 1,2,3,5 and 7 days respectively after intracerebral hemorrhage. The rat"s packed red blood cells, lysed red blood cells and hemoglobins at different concentrations were injected respectively into the rat"s caudate nucleus. The changes of edema in various regions of the brain at different time were measured as above. 5U thrombin was injected into the rat"s caudate nucleus and the changes of edema in various regions of the brain at different time were measured as above.

自体股动脉取血，并采用自体未肝素化新鲜血回注法建立大鼠尾状核出血模型，观察脑出血后1，2，3，5，7天血肿同侧基底节区、血肿同侧对应的皮质区、血肿对侧对应的基底节区及血肿对侧对应的皮质区脑组织水分含量的变化；分别以自体浓缩红细胞(PRBC，50％)、溶解红细胞(LRBC，50％)、不同浓度的大鼠血红蛋白注入大鼠尾状核，并观察不同时间不同部位脑组织水分含量的变化；以5U凝血酶注入大鼠尾状核，观察不同时间不同部位的脑组织水分含量的变化。

The animal model of this method system have, the characteristics of the high fat, high leptin, high Ins, and match with the characteristic of clinical and the pathologic of simple obesity. This studies showed: The acupuncture can obviously reduce the vaule of intaking food and water of the fat rats, and lower the body weight and fat; The acupuncture can urge the diameter, area, physical volume of white fat cell contract, Brown fat tissue of fat rat group surroundings vascular containing large quantity of white fat cell, the acupuncture group was less. this showed: The acupuncture enhanced the white fat cell metabolism, and promotesed the white fat cell to convert to brown fat cell; The frequency of spontaneous electric of nerve cell of pvn of the fat rat is high, the acupuncture counld depress the spontaneous electric of nerve cell of pvn, This showed: the acupuncture can depress the appetite passing to adjust function of pvn nerve; The monoaminergic neurotransmitter of inside of the fat rat brain is disfunction, the acupuncture can rectify this disfunction, and adjust level of 5-HT, and affect appetite, and improve metabolism; The level of leptin and Ins of fat rat increased high, The level of it of acupuncture group decreased, compared with the fat group p.001, This showed: the fat rats have the defeat of leptin and Ins in the body, The acupuncture can lowering this defeat, The level of leptin and Ins of the fat rat in the brain is less than the normal group, The level of leptin of the acupuncture group is high than the fat group, This showed: the acupuncture can increase the transportation of leptin from blood to brain.

本方法所制肥胖大鼠模型具有高体重、高脂、高leptin和高Ins血症的特点，符合人类单纯性肥胖病的临床和病理特征；实验研究显示：针灸能明显减少肥胖大鼠的摄水、摄食量及降低其体重、体脂；针灸能促使白色脂肪细胞直径、面积、体积缩小，减少肥胖大鼠棕色脂肪组织血管周围白色脂肪细胞数量，显示：针灸增强了白色脂肪细胞的代谢，促进了白色脂肪细胞向棕色脂肪细胞的转化：肥胖大鼠PVN神经细胞自发放电频率增加，脑内单胺递质紊乱，针灸通过抑制PVN亢奋的自发放电，调整5-HT水平，达到影响食欲，改善代谢的作用；肥胖大鼠血中leptin及Ins水平增高，与正常组大鼠比有明显差异，提示大鼠体内存在leptin及Ins抵抗，针灸后肥胖大鼠随着体重体脂的下降，血中leptin、Ins水平降低，与肥胖组比均有显著性差异，而针灸后大鼠脑内leptin增加，与肥胖组比P.05，提示：针灸具有改善leptin、Ins抵抗及增加leptin脑内转运的作用。
