乳酸菌与中药合生元对肉鸡生长性能及饲料利用率的影响

本试验分别向肉仔鸡日粮中添加等量的抗生素和乳酸菌与中药合生元制剂,通过测定肉仔鸡的各项生长指标和饲料利用率指标,探讨乳酸菌与中药合生元在肉鸡生长和饲料利用率方面替代抗生素的优势.结果表明,试验组与对照组在生长性能和饲料利用率上各指标均差异不显著（P〉0.05）,说明乳酸菌与中药合生元可以替代抗生素饲喂给肉仔鸡.     

宠物犬的几种调教和训练方法

一、定点排便。具体方法．在一个固定的地方做一个便盆，里面放上旧报纸或旧布块，上面铺一些沙土。在犬可能排便的时候，如喂食后、早晨起床后、晚上睡觉前，在犬有嗅认、转圈、不安、翘尾、下蹲等前兆行为时，及时呼唤犬名，将犬带到放有便盆的地方，诱导犬到便盆内排便。如犬能在便盆内大小便，就要给犬食物和抚拍奖励，让犬知道这是主人喜欢的。经过耐心地调教，犬就能养成在固定地点大小便的良好习惯。

稻属植物21个种颖花稃尖的比较研究

用扫描电镜对稻属植物２１个种颖花稃尖进行观察,看到外稃尖的两侧各个一个突起或折痕。根据其形状不同,将２１个稻种的外稃尖分为“乳突型”、“钝角型”、“折痕型”和“融合型”４种型。     

Arbovirus isolations from mosquitoes in South Slovakia.

In the years 1973 and 1975 mosquitoes and some other Diptera (Tabanidae, Simuliidae, Hippoboscidae) were tested for virus. 13,924 mosquitoes, 75 horseflies and 60 blackflies were processed in 1973. Five strains of Tahyna virus were isolated from mosquito species Aedes vexans. 3,378 mosquitoes and 12 sheep keds were tested for virus in 1975. Twelve strains of Calovo virus were isolated from Anopheles maculipennis and one strain of Tahyna virus was obtained from Aedes vexans mosquitoes.

and laminin on adhesion and proliferation of human hepatocellular carcinoma cell

AIM:To explore the effects of PMA(phorbol-12-myristate-13-acetate, a tumor promoter, mimicking the action of diacylglycerol on PKC)and laminin on the adhesion and the proliferation of human hepatocellular carcinoma cells, and provide a new clue to liver cancer treatment.METHODS:Human hepatocellular carcinoma cell line(BEL-7402)was used to identify the endogenous laminin and protein kinase C-α(PKC-α) expression, and the effects of laminin and PMA on the adhesion and the proliferation were also investigatedin vitro.RESULTS:By the effect of exogenous laminin, human hepatocellular carcinoma cell (BEL-7402) possessed endogenous laminin expression and increased the adhesion and the proliferation, which was showed the synergistic action by the effect of PMA in combination. By the action of PMA alone, the proliferation and the PKC-α expression increased by exogenous laminin were decreased, and the adhesion and the endogenous laminin expression were increased.CONCLUSIONS:The finding suggested that the adhesion and the proliferation of human hepatocellular carcinoma cell were closely related to the effects of endogenous or exogenous laminin, which were associated with cPKC-α activity. Therefore, the application of anti-laminin antibody in combination with PKC antagonist might be a new clue to find out the therapy for liver cancer.
