Moreover, CoI gene was more conservative and a lower evolutionary rate than Cyt b gene. CoI gene was an effective marker in analysing the phylogenesis of families in Passeriformes. It can be used in identifying the species of Passeriformes, but it was revealed that CoI gene was more suitable to identify the phylogenetic relationship of avian family unit than Cyt b gene, and CoI gene can be a molecular marker to identify avian species. But in species identification, CoI gene was less stable and accurate than Cyt b gene. We suggested youd better employ the other marker if you have the CoI gene only.(2) In the phylogenetic trees of birds from Lanius, L.

比较分析了雀形目6科15种鸟类的细胞色素b全序列和CoI基因部分序列，结果显示细胞色素b和CoI基因序列的变异位点分别为454个和366个、简约信息位点为337个和303个，而且线粒体CoI基因比细胞色素b基因略微保守、进化速率也较低；CoI基因在确定雀形目科级阶元之间的系统发生关系方面是一种有效的分子标记，同时它也能够用于雀形目鸟类的物种鉴定，但在物种鉴别方面不如细胞色素b基因稳定、准确。

Generally we think muscular histogenesis has many steps of biology, including foetal mesoderm merotomy; myoblast shapes in arthromera; myoblast can form muscular tissue to move to limbs; the proliferation of sarcoblast can increase cells\'quatity.

一般认为，肌组织发生是一多步骤的生物学过程，包括胚胎中胚层的分节；成肌细胞在体节形成；成肌细胞向四肢迁移形成肌组织；成肌细胞增殖以增加细胞数量。

The process of osteoarthritis mesochondrium degradation is possibly attributed to the synergistical consequence of MMPs and other factors. Pilose antler peptide can promote the proliferation of OA chondrocytes of rabbits ,inhibit the overexpression of MMPs of OA chondrocytes.It can possibly play a effective role in the treatment of OA.

结论骨性关节炎软骨细胞在骨性关节炎发病过程中，软骨细胞正常分化及增殖发生改变；骨性关节炎软骨基质降解过程可能是金属蛋白酶与其它因子协同作用的结果；鹿茸多肽可促进骨性关节炎软骨细胞增殖，并可抑制骨性关节炎软骨细胞中金属蛋白酶的过度表达，可能对治疗骨性关节炎有较好的作用。

Extracellular calcium is required for normal progression through the initial recognition-alignment phase of myogenesis. A net calcium influx into fusion-competent myoblasts is a requisite step in membrane fusion.

细胞与细胞之间识别和并列的初期阶段，胞外钙离子的内流是正常肌细胞生成过程所必不可少的，钙离子进入具有融合潜能的成肌细胞内，从而使细胞膜发生融合。

In conclusion, features of morohopathology, IHC profile and ultrastructural findings reveal obvious divergence between CHP and HP and resemble MP, so we suggest that histogenesis of CHP is pericyte with myoid differentiation.

根据此研究之结果得知，无论在肿瘤发生部位、组织病理形态学、免疫组织化学染色结果以及超显微结构的特徵，CHP与HP具有明显的差异性，反而与MP之特徵较为相近，此结果可间接证实CHP之肿瘤细胞来源与MP的肿瘤细胞之来源较为相似，可能为血管周围细胞来源并具有类肌肉细胞的分化。

The results showed that : 1 During nonbreeding season, the giant panda′s ovary was still rich with large and small follicular oocytes, and the large follicular oocytes could be matured in vitro; 2 The mean diameter of the oocytes was (141±6.7)μm and lots of cortical granules contained in the cytoplasm of oo...

结果表明∶（1）在非繁殖季节，大熊猫卵巢中小腔及大腔卵泡卵母细胞仍较丰富，其大腔卵泡卵母细胞可在体外培养成熟；（2）大熊猫的卵母细胞平均直径为（141±6.7）μm ，其胞质富含卵黄颗粒；（3）自配 PandaI I号获能液（含丙酮酸钠、肾上腺素等）可使大熊猫精子有效获能；（4）大熊猫卵母细胞体外受精后，经培养可观察到第2 极体，有的受精卵开始发生卵裂。

The results showed that the rates of mature oocyte were 75.2％, 73.1％, 69.8％, 63.5％and oocyte at telophase of MI were 16.3％, 15.9％, 16.9％, 27.0％, respectively. The rates of maturation of oocytes cultured in TCM199 with serum, EGF and TGFαwere significantly higher than that of with BSA team (P＜0.05) and the number of oocyte stayed at telophase of MI in TCM199 with serum, EGF and TGFαteam were significantly less than that with BSA team(P＜0.05); Significant higher rates (66.6％, 66.6％, 73.6％) of normalα-tubulin distribution in oocytes cultured in TCM199+ serum, EGF and TGFαwere compared to that of TCM199+BSA(43.3％)(P＜0.05). The rates of oocyte with cortical granules in cortex were 58.8％, 33.9％, 54.7％and 47.9％respectively, there was significant difference between oocytes cultured with serum, EGF and BSA(P＜0.05). In conclusion, TGFαand EGF can promote the oocyte nuclear transition from telophaseⅠto metaphase of meiosisⅡ, and improved the expression and distribution ofα-tubulin during the ovine oocytes maturation; EGF and serum could promote oocyte cytoplasm maturation. The results suggested that EGF and TGFαmight substitute some substance in serum to improve the quality of oocyte nucleus maturation in vitro, but EGF might be more functional than TGFαto promote the maturation of ovine oocyte ooplasm.

三、EGF和TGFα对卵母细胞成熟的影响未成熟卵母细胞分别在TCM199基础培养液+血清、TCM199基础培养液+BSA+EGF、TCM199基础培养液+BSA+TGFα和TCM199基础培养液+BSA四组成熟培养系统中成熟培养，22小时后上述各组卵母细胞的核成熟率分别为75.2％、73.1％、69.8％、63.5％，处于第一次减数分裂末期的比率分别为16.3％、15.9％、16.9％、27.0％，在添加血清、EGF、TGFα各组中核成熟率显著高于其它各组(P＜0.05)，处于末期的比例明显低于其它各组(P＜0.05)：添加血清、EGF、TGFα各组在a-Tubulin蛋白的分布与表达上(66.6％、66.6％、73.6％)明显高于BSA组的正常率43.3％(P＜0.05)；各组CG发生迁移较好的卵母细胞的比率分别为58.8％、33.9％、54.7％、47.9％，血清组和添加EGF组CG迁移至皮质区的比例明显高于仅添加BSA处理组(P＜0.05)。
