Results:①In normal extracellular solution, the non-selective cholinergic agonist acetylcholine and the muscarinic agonist muscarine both caused the increace of [Ca2+]i in separately 21 out of 25 and 14 out of 18 VHCs I, while only 3 out of 20 and 2 out of 16 VHCs I had a weak increase of [Ca2+]i if investigated in calcium free extracellular solution; nicotine could increase the [Ca2+]i in 7 out of 32 VHCsⅠonly at enough high concentration(up to 10 mmol/L) in normal extracellular solution, this [Ca~(2+)]_i increase by nicotine at high concentration could not be investigated if at calcium free solution.

结果①非选择性胆碱能受体激动剂乙酰胆碱、M型胆碱能受体激动剂毒蕈碱在正常细胞外液中均可引起大部分(21/25， 14/18)单离VHCⅠ[Ca~(2+)]_i的升高，但无钙外液中ACh、muscarine仅使少部分(3/20，2/16)VHCⅠ[Ca~(2+)]_i升高且作用减弱；正常外液中，N型受体激动剂尼古丁仅在高浓度(≥10 mmol/L)时引起部分(7/32) VHCⅠ[Ca~(2+)]_i升高，在低浓度时对胞内钙离子浓度影响不明显，无钙外液中，10 mmol/L nicotine对胞内钙离子浓度影响不明显。

结果表明： 5个绵羊品种在引物2的扩增产物中均存在单核苷酸多态性，其中只有多赛特羊未检测出DD型，而其余4个绵羊品种均检测出CC、CD和DD型。

115 caprine right femurs were taken and created to simulate AO/33-A3 fracture. All fracture models were fixed by the right 5 hole LISS Plate, which treated differently by using unicortical or bicortical screws in the proximal end of the LISS plate. And then withdrawal force and torsional force were given on them to make comparison.
