| | Using randomized block design,24 sika deers,aged 3 to 4 years and weighted 100 to 120 kg,were divided into 2 groups Sika deers were tethered or calmed with mechanical (group A) and medicinal (group B) methods respectively, for antlers cut The concentrations of plasma hydrocortisone and some biochemical parameters of blood were tested The results were as follows:The contents of plasma hydrocortisone and blood sugar of sika deers in group A ... | | 24头健康、3~4岁、体重100~120kg的锯茸期梅花鹿随机分为两组,分别用木笼绳索保定法(A组,n=12)和药物保定法(B组,n=12)进行锯茸。对血浆皮质醇含量及部分血液生化值的改变进行了测定。试验结果,A组锯茸后血浆皮质醇和血糖含量较试验前呈突发性升高,然后逐渐下降,两者的改变呈正相关(r=0.94),1~9日内各次测定值间及与B组间差异均极显著(P<0.01);血浆CO2cp值锯茸后3~5日内呈明显下降;血Na+、K+、Ca+值均呈上升势态,1~7日内各次测定值间及与B组间均有极显著差异(P<0.01);B组锯茸前后各项指标各次测定值间差异不显著(P>0.05)。 | | 文摘来源 | | To investigate anti-disease and anti-bacteria related non-specific immunological factors of Scylla serrata.Scylla serrata were randomly divided into 3 groups:control group,group 1 and group 2,10 samples of each group.The control group was not infected.The group 1 and group 2 were separately injected with live and inactivated Vibrio parahaemolyticus (5.0×107/mL).Seven days later,they were infected the again with live V.parahaemolyticus,respectively,labeled as group 1~7 and 2~7.Eighteen hours later after each... | | 采用蛋白质组学技术对锯缘青蟹受细菌感染后血淋巴中蛋白表达变化的情况进行初步研究.试验中以未感染锯缘青蟹为对照,用密度为每毫升5.0×107个副溶血弧菌的菌液感染锯缘青蟹,于注射后18h分别抽取活菌注射组、灭活菌注射组、空白对照组的锯缘青蟹的血淋巴,进行蛋白差异分析.结果发现,与对照相比,锯缘青蟹感染细菌后,血淋巴中出现1条明显差异条带.肽质量指纹图谱及生物信息分析表明,该蛋白为cryptocyanin,是血蓝蛋白基因家族中的重要成员,提示cryptocyanin与免疫反应有关. | | 文摘来源 | | The regulation of three biogenic amines over the reproductive neuroendocrine activity of male Scylla serratawas investigated byin vivo injection and in vitro incubation.The testicular index,the ratio of the mature sections among the seminiferous tubules,and the ratio of Type B cells among the androgenic glandular cells were taken as the quantitative indexes.In vivoinjections indicated that: 5-HT can significantly promote the testicular development and the secretion of the androgenic gland in S.serrata;DA ca... | | 采用活体注射和体外培养方法,以精巢指数、精巢生精小管的成熟节段比例和促雄腺B型细胞比例为量化指标,观察3种生物胺对雄性锯缘青蟹生殖神经内分泌的调控作用.活体注射实验表明:5-HT组锯缘青蟹精巢发育和促雄腺分泌活动具有显著的促进作用;DA组精巢发育受到抑制,但促雄腺细胞的分泌活动不受影响;OA组与同步对照组差异不显著.离体实验表明:5-HT刺激了脑和胸神经团的分泌活动,从而促进促雄腺分泌活动;OA和DA对脑和胸神经团分泌活动没有明显影响.视神经节的生殖内分泌活动几乎不受3种生物胺的影响.本实验首次报道了体外条件下生物胺对雄性甲壳动物生殖神经内分泌的调控作用,支持了5-HT首先刺激脑和胸神经团分泌GSH,再通过促雄腺活动从而促进精巢发育的观点. | | 文摘来源 | |   |
