Effects of I.M. injections on serum creatine phosphokinase (CPK) values in dogs     

Lewis HB  Rhodes DC 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1978,7(2):11-13

Intramuscular injections of compounds of low irritancy (bicillin, valium, saline) were found to cause significant elevations in serum CPK in dogs. This route of treatment must therefore be avoided in clinical conditions where CPK values have diagnostic or prognostic importance.  相似文献   

Apoptosis induced by simvastatin in rat vascular smooth muscle cells through calpain and caspase-3-dependent pathways     

CHENG Gang  XU Geng  SHAN Jiang  HUANG Jin-yu  ZHOU Hua 《园艺学报》2003,19(9):1189-1192

AIM:Hydroxymethylglutaryl CoA (HMG-CoA) reductase inhibitors, such as simvastatin, have been shown to reduce atherosclerotic cardiovascular morbidity and mortality by mechanisms unrelated to its lipid-lowering effect. Several studies have shown that simvastatin induces apoptosis in a varieties of cell lines including vascular smooth muscle cells (VSMC). The aim of this study was to investigate the signal pathways involved in apoptosis induced by simvastatin.METHODS:Cultured VSMC were treated with simvastatin. Calpain activity was determined by measuring Ca²⁺ ionophore-specific calpain substrate (suc-LLVY-AMC), caspase-3 activation was detected by Western blot, and apoptotic changes were distinguished by annexin Ⅴ binding and DNA laddering.RESULTS:After incubated with 30 μmol/L simvastatin for 8 h, calpain activity had a marked increase (P<0.05, n=4) and reached to more than 3-fold of control at 12 h (P＜0.01). Caspase-3 also activated by simvastatin after 12 h. PD150606, a cell-permeable selective calpain inhibitor, decreased simvastatin-induced apoptosis rate from 24.2%±1.7% to 9.5%±1.9% (P＜0.01) and also prevented simvastatin-induced DNA laddering. Furthermore, 100 μmol/L PD150606 efficiently inhibited simvastatin-induced caspase-3 activation.CONCLUSION:Simvastatin induces apoptosis by activating caspase-3 via calcium-dependent protease calpain.  相似文献   

The disturbance of calcium metabolism of vascular smooth muscle in the late phase of septic shock and the underlying mechanism     

DING Yue-min  SHAN Qi-xian  ZHANG Xiong  JIN Hong-feng  TU Jie  XIA Qiang 《园艺学报》2003,19(11):1484-1487

AIM: To evaluate the alterations in calcium metabolism of the vascular smooth muscle in the late phase of septic shock and test the hypothesis that nitric oxide might be involved in sepsis-induced vascular hyporeactivity. METHODS: Male Sprague-Dawley rats were subjected to sepsis by cecal ligation and puncture (CLP). 18 hours post CLP, rat aortic rings were employed for measurement of contractile responses by using organ bath technique. RESULTS: In endothelium-denuded aortic rings from CLP rats, concentration-contraction curves to phenylephrine (PE) and KCl were significantly decreased when compared to that from sham control rats. The transient contraction induced by PE in calcium-free Krebs solution and the concentration-dependent contraction to CaCl₂ in KCl-depolarized medium were also markedly reduced. The hyporeactivity was partially reversed by treatment with aminoguanidine, a selective inducible nitric oxide synthase inhibitor. CONCLUSION: An impairment in calcium handling in vascular smooth muscle is involved in the vascular hyporeactivity during the late phase of septic shock, in which an excessive nitric oxide production might be the major mechanism.  相似文献

The effects of short-term recombinant bovine somatotropin treatment on fattening performance,carcass composition and visceral organ weights in karayaka lambs in Turkey     

Balci F  Orman A 《Tropical animal health and production》2008,40(4):255-260

Recombinant bovine somatotropin (bST) was administered s.c. to lambs for 6 weeks to evaluate its effects on fattening performance, carcass composition and visceral organ weights. Twenty male Karayaka lambs were injected with 250 mg bST every two weeks. Body weight, live weight gain, feed intake and feed conversion rate were not affected by treatment. Head, feet, skin, liver, spleen, kidneys, filled and empty gastrointestinal tract, penis, testis, pelvic fat and internal fat weights were similar for the two groups. Lung weight increased by 17.4% (P < 0.01) and weight of heart decreased 22.7% (P < 0.05) in bST treated lambs. The only carcass characteristics that were affected by bST administration were limb muscle which increased from 1331 g to 1417 g (P < 0.05), loin fat which decreased from 275 g to 174 g (P < 0.01), shoulder fat which decreased from 26 g to 13 g (P < 0.01) and total fat/final weight percentage which decreased from 9.8% to 7.6% (P < 0.05). The results of this study show that prolonged release formulation of bST treatment reduces fat tissue, but does not significantly affect fattening performance or weights of visceral organs, muscle and bone.  相似文献

徐升胜  李兵  许西奎  沈卫德 《安徽农业科学》2009,37(18):8377-8379

[目的]克隆家蚕副肌球蛋白／小副肌球蛋白基因,分析该基因与运动性状的关系。[方法]利用PCR扩增和RACE技术获得了家蚕（Bombyx mori）副肌球蛋白的全长cDNA和小副肌球蛋白的部分cDNA;经检索家蚕wgs（基因组散弹序列）数据,获得了家蚕副肌球蛋白／小副肌球蛋白的基因组序列,并确定其基因组结构。[结果]家蚕PM/mPM基因由17个外显子和16个内含子组成,通过基因内部选择性启动子的使用,该基因组序列同时编码副肌球蛋白和小副肌球蛋白,小副肌球蛋白和副肌球蛋白共用最后6个外显子。家蚕副肌球蛋白与其他无脊椎动物副肌球蛋白的聚类分析表明,家蚕和野桑蚕有最近的亲缘关系,在昆虫纲中与黑腹果蝇关系最远。[结论]家蚕和野桑蚕副肌球蛋白的氨基酸序列间不存在可引起飞行缺陷的点突变,推测家蚕和野桑蚕飞行能力差异存在其他调控机制。  相似文献
