广东眼镜蛇蛇毒与眼镜王蛇蛇毒冻干粉的鉴别及质量控制的研究 V．广东眼镜蛇蛇毒与眼镜王蛇蛇毒的氨基酸分析

本文采用日立８３５－５０型氨基酸自动分析仪测定了广东眼镜蛇蛇毒与眼镜王蛇蛇毒的氨基酸成分,结果表明两种蛇毒的氨基酸组成基本相同,但多种氨基酸的含量存在明显差异,为蛇毒鉴别和质控提供实验依据。     

蝮蛇咬伤的中医证治体会

蝮蛇咬伤的中医证治体会周文华江苏省太仓市沙溪镇沙北医疗室２５５４２１１前言蝮蛇是我国分布最广、数量最多、为害最普遍的主要毒蛇,亦是我省唯一的毒蛇。在人口稠密的苏南地区,蝮蛇咬伤有很高的发病率,个别地区的年发病率达１６‰。从历年的临床病例来看,本病如无...     

蝮蛇抗栓酶对家兔慢性胆囊炎防治的实验研究

作者用家兔４２只随机分成造型组（Ａ）,预防组（Ｂ）及治疗组（Ｃ）。各组又分处理组（Ａ１、Ｂ１、Ｃ１）和对照组（Ａ２、Ｂ２、Ｃ２）两个亚组。Ａ２组仅喂基本饲料,其余５组喂基本饲料加造型剂。Ａ组没用任何治疗。Ｂ１组慢性胆囊炎形成前,Ｃ１组慢性胆囊炎形成后分别用蝮蛇抗栓酶（０．２Ｕ／ｋｇ／日３０天）,Ｂ２和Ｃ２组仅给等量生理盐水。Ａ２及治疗后的Ｂ１、Ｃ１组血清胆固醇含量均明显低于Ａ１、Ｂ２、Ｃ２组（Ｐ＜０．０５）。胆囊的病理变化,Ｂ２和Ｃ２组改变明显,表面呈暗褐色,与周围组织粘连,粘膜面粗糙,胆囊壁增厚,体积增加,胆汁潴留,镜下粘膜增生呈乳头状,部分粘膜脱落,粘膜下及肌层水肿,炎细胞浸润。结果表明,蝮蛇抗栓酶对慢性胆囊炎既有预防作用又有治疗作用。     

不同蝮蛇抗栓酶对动物的神经毒性敏感反应

给小鼠、家兔、豚鼠等３种动物注射不同剂量的两种蝮蛇抗栓酶,观察它们的反应。结果：东北白眉蝮蛇抗栓酶未见神经毒反应,而浙江蝮蛇抗栓酶有神经毒反应,以豚鼠的反应最为敏感,主要表现为箭毒样毒性症状

Studying dynamic process of photosensitization by ESR method

By kinetic methods, functional relation of TAN radical, produced in the process of TEMPONE trapping O2, vs. time during photosensitization was established. Accordingly relative rate constants of generating all kinds of active intermediates through types I and II mechanism of photosensitization can be calculated. Using the formula and experimental results, the relative rate constants of generating O2, O2 and PS2 of three kinds of perylenequinone photosensitizer: HA, HB and CP in DMF-H20 and DMSO-H2O system were calculated, and then the structure-activity relationship of perylenequinone photosensitizer and the relation between photosensitivity and solvent was studied.     

New red flower germplasm lines of cotton selected from hybrid of Gossypium hirsutum × G. bickii

By means of dropping GA3 (50 ppm) and NAA (40 ppm) on the hybrid boll-embryo culture in vitro, one F1 plant of G. hirsutum G. bickii was obtained; when F1 branches were grafted on upland cotton and then back-crossed with upland cotton under short-day and cooler-night condition, some BC1 seeds could be harvested. The characteristic segregation was very violent in early generation. Through 3 times of back-crossing and selecting, ten stable hybrid lines with the character of both male parent (viz. red petal-purple spot and strong fibre) and female par-ent (plant type, earliness, white fibre, lint length, etc. ) were established. These lines were assigned as HB red flow-er lines (HBRL). Transference of character of G. bickii to upland cotton was proved to be successful for the first time. These new germplasms may play an important role in both the genetic research and new cotton variety breeding.
