These findings will undoubtedly contribute to a deeper understanding of snake venom evolution and diversification, the mechanism of the envenomation and the design of new drugs in search of leading compounds.

这些结果不仅有助于增强人们对毒素进化与分化以及中毒机理的了解，并对新药设计中的先导化合物寻找具有重要意义。

The adult reproductive system of Epicauta mannerheimi and Mylabris phalerata were dissected and a histological study was made on the reproductive gland of Myllabris phalirata .

芫菁为鞘翅目芫菁科昆虫，其成虫和幼虫体内均含有一种倍半萜烯毒素——芫菁素 [1] ，因芫菁素不仅可以医治多种癌症，还可升高人体白血球，而成为一种重要的药用昆虫。

Objective To study the effects of podophyllotoxin solid lipid nanoparticles on the proliferation of human epidermal cells in vitro.

目的研究鬼臼毒素固体脂质纳米粒对人表皮细胞增殖的影响。

Background and objective: Rhomotoxin, the active constituent of Rhododendron molle belonging to Ericaceae, has the effects of decreasing blood pressure and slowing heart rate. These effects can exacerbate and remain 0.5-1 hour after drug withdrawal, which is prone to cause lower blood pressure even shock.

背景与目的八厘麻毒素(rhomotoxin，RTX)系从植物杜鹃花科羊踯躅成熟果实中提取的有效成份，具有较强的降压、减慢心率作用，但其降压作用在停药后0.5-1小时仍继续加深，易引起降压过度而导致休克，同时血中浓度检测困难，不易监控，临床上应用较难掌握。

Zeae, is one of the most important diseases in rice. Genetic and molecular characters of toxin producting for Erwinia chrysanthemi pv.zeae were conducted in this paper.

zeae是水稻上重要的细菌病害之一，本论文对该病菌的毒素遗传特性和产毒相关的分子标记进行了研究。

In these prevalent areas of HBV infection and risky regions of HCC,HCV has not become the main and sole etiogenic,neither is it a rare phenomenon.

HCV感染虽非HCC的主要发病因素，HCV引起肝细胞损伤，增加肝细胞对HBV 及其它致癌因素如黄曲霉毒素的敏感性，加快肝癌发生进程。

Mucous membrane protective screen is formed by the join between cell of alvine mucous membrane and cell, atrophy of cell of alvine mucous membrane, wither dies, cellular connective can send alvine path to connect flabbily appear a gender to increase, provide passageway; chemical protective screen for the bacterium inside bowel and toxin the digestive juice that shows epithelial excretive mucus and alvine memory are in bowel and digest enzymatic the chemistry that waits for material to reach its to develop.

黏膜屏障由肠黏膜细胞和细胞间的连接构成，肠黏膜细胞萎缩、凋亡、细胞连接的松弛可致肠道通透性增加，为肠内细菌及毒素提供通道；化学屏障指肠上皮细胞分泌的黏液及肠内存在的消化液和消化酶等物质及其发挥的化学功能。

Objective To investigate the exfoliative toxin serotype genes and antibiotic resistance of Staphylococcus aureus isolated from children with staphylococcal scalded skin syndrome.

目的 探讨葡萄球菌性烫伤样皮肤综合征致病的金黄色葡萄球菌分泌表皮剥脱毒素的主要类型及耐药情况。

Exfoliative toxins of Staphylococcus aureus are directly responsible for the skin exfoliation of staphylococcal scalded skin syndrome.

由金黄色葡萄球菌分泌的表皮剥脱毒素是引起葡萄球菌性烫伤样皮肤综合征患者皮肤剥脱的直接原因。

This may partially attribute to packaging an inclusion within the hydrophobic exosporium so as to keep the inclusion in the water where target larvae maybe actively feeding.

可能是因为芽胞在昆虫肠道内再次萌发，产生了其他致病因子，如肠毒素、溶血素等，与杀虫晶体蛋白协同作用；也可能是因为伴胞晶体受到疏水的芽胞外壁层保护而能在水中等一般伴胞晶体不容易存在的地方被易感昆虫摄食。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
