The intraperitonealLD_(50) values in mice of VES and VDPG were 0.16mg/kg and 0.39mg/kg,respectively. The intraperitoneal LD_(50) value in cockroach of VDPG andVES were 2.32μg/g and 1.87μg/g, respectively. After intraperitonealinjection of the venom in mice, the main poisoning symptoms includedlethargy, ataxia, diaphoresis, convulsion, anorexia, shortness of breath,and difficulty to open eyes, etc. Whereas the mice injected withphysiological saline acted normally.

两种粗毒都对小鼠和蜚蠊有较强的毒性，其中毒囊粗毒和电刺激粗毒对小鼠的LD_(50)值分别为0.39mg／kg和0.16mg／kg；毒囊粗毒和电刺激粗毒对蜚蠊的LD_(50)值分别为2.32μg／g和1.87μg／g体重；小鼠经腹腔注射粗毒后，出现无生气、共济失调、排汗、痉挛、食欲减退、呼吸短促、睁眼困难等症状，而注射生理盐水的小鼠活动正常。

After 180-min stress, the diencephalon contents of 5-HT and 5-HIAA correlated positively with the plasma levels of corticostreone and 〓· These results indicate that brain 5-HT participates in the activation of hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes during stress.

甲状腺切除还可以阻断侧脑室注射5-HT引起的加重溃疡形成的作用，而地塞米松预处理则无此作用，提示侧脑室注射5-HT加重溃疡的作用主要通过兴奋HPT轴实现。

When proceeding the research of drug identification by ultraviolet spectrophotometry, this paper adopts the approaches below: to identify Metronidazole Buccal Tablets and Potassium Sodium Dehydroandroan Drographolide Succinate by ulviolet maximum absorbent wavelength; to identify Metronidazole Disodium Phosphate for Injection by ulviolet maximum absorbent wavelength and minimum absorbent wavelength; to identify Ceftriaxone Sodium for Injection and Clarithromycin Tablets by retention time of high performance liquid chromatography- ultraviolet spectrophotometry.

通过测定紫外最大吸收波长λ_(max鉴别甲硝唑口颊片和炎琥宁、测定紫外最大吸收波长λ_(max和最小吸收波长λ_(min鉴别注射用甲硝唑磷酸二钠，结合高效液相色谱(high performance liquid chromatography-ultraviolet detector，HPLC-UV)中保留时间的测定鉴别注射用头孢曲松钠和克拉霉素片，本文建立了药物鉴别的紫外分光光度法。

The research indicates that:(1) detecting λmax (277nm) can identify Metronidazole Buccal Tablets prepared by Chongqing Medical College;(2) detecting λmax (321nm) and λmin (265nm) can identify Metronidazole Disodium Phosphate for Injection prepared by Chongqing Medical College;(3) detecting tr (6.7min) in HPLC-UV spectrum can identify Ceftriaxone Sodium for Injection prepared by Chongqing Keru Pharmacy Co.;(4) detecting tR (10.2min) 6.7min in HPLC-UV spectrum can identify Clarithromycin Tablets prepared by Harebin Yida Pharmacy Co.;(5) detecting λmax (254nm) can identify Potassium Sodium Dehydroandroan Drographolide Succinate prepared by Hong Kong Yaohen Co..

结果表明：①测定紫外最大吸收波长λ_(max277nm可鉴别重庆医科大学医药研究所制备的甲硝唑口颊片；②测定紫外最大吸收波长λ_(max321nm和最小吸收波长λ_(min265nm可鉴别重庆医科大学医药研究所制备的注射用甲硝唑磷酸二钠；③测定HPLC-UV中的保留时间(t_R6.7min)可鉴别重庆科瑞制药股份有限公司制备的注射用头孢曲松钠；④测定高效液相色谱的保留时间(t_R10.2min)可鉴别哈尔滨伊达制药厂提供的克拉霉素片；⑤测定紫外最大吸收波长(又max254nm)可鉴别香港耀恒公司提供的炎琉宁。
