A method to evaluate the irritating action of furapromidum (F 30066) on mouse stomach is described. Mice receiving oral doses of the drug were immediately given intravenous injection of 1% Evans blue in normal saline and were sacrificed by bleeding 2 hours later. At autopsy, the stomach was everted and the extent of the blue staining on the serous layer of the fundus was assessed visually on an arbitary scale (0-8). It was shown that the degree of blue staining caused by a single dose of furapromidum or xylol...

A method to evaluate the irritating action of furapromidum (F 30066) on mouse stomach is described. Mice receiving oral doses of the drug were immediately given intravenous injection of 1% Evans blue in normal saline and were sacrificed by bleeding 2 hours later. At autopsy, the stomach was everted and the extent of the blue staining on the serous layer of the fundus was assessed visually on an arbitary scale (0-8). It was shown that the degree of blue staining caused by a single dose of furapromidum or xylol correlated well with the severity of the pathological changes of that organ.Eleven drugs were tested for their antagonistic action to the irritating effect of furapromidum on mouse stomach. Drugs were given orally 1 hour before the administration of furaprornidum. It was found that chlorpheniramine, phenergan,diphenhydramine and chlorpromazine were quite active in limiting the extent of blue staining, indomethacin and mefenamic acid showed only moderate effect while atropine exhibited little effect, if at all.When mice were given furapromidum orally in the dosage of 500 mg/kg daily for 10 days, it was found by the Evans blue method that the irritating effect of the drug was reduced gradually with the increasing number of doses. The irritating action of the last dose was only about one-third that of the first. However, if chlorpheniramine was given orally 1 hour before administration of furapromidum during the first 3 days of the course, the irritating effect became evident only on the third day, and in a lcss degree than that of the corresponding group given furapromidum alone, and it gradually disappeared as the treatment was continued. These results correlated basically with the gross and microscopic pathological alterations of the stomach. The antischistosomal effect of furapromidum was practically not affected by chlorpheniramine.

本文介绍用伊文思蓝法观察呋喃丙胺对小白鼠胃的刺激作用。动物于口服药物后即由尾静脉注入1%伊文思蓝,并于2小时后剖杀取胃,根据胃底浆膜面的蓝色色素沉着情况,评价药物对胃的刺激作用。试验证明,小白鼠一次口服呋喃丙胺或二甲苯后,用伊文思蓝法观察药物对胃的刺激作用与组织病理学的观察结果相仿。这种方法具有操作简便、快速、灵敏和重现性高等优点。在拮抗试验中,发现扑尔敏、异丙嗪、苯海拉明和氯丙嗪具有较强的拮抗呋喃丙胺对鼠胃的刺激作用,抗炎类药物次之,而阿托品则甚差。用伊文思蓝法观察的结果表明,小白鼠每天口服呋喃丙胺500 mg/kg,连续10天时,药物对鼠胃的刺激作用逐渐减轻,至给药10天后,胃的刺激反应仅及第1次给药时的1/3。若在疗程的第1~3天,每天于口服呋喃丙胺前1小时先服扑尔敏,则呋喃丙胺对鼠胃的刺激作用,仅在给药的第三天较明显,但轻于单服呋喃丙胺3天组。用肉眼或组织病理学方法观察胃肠病变的结果,与伊文思蓝法的基本一致。扑尔敏不影响呋喃丙胺的抗血吸虫作用。

Among the phytoplankton samples collected between May and June in 1979 from a high-yielding fish pond near the Yangtze River Bridge we have discovered a blue-green specimen of the genus Gymnodinium Absorption, fluorescence emission and excitation spectra have proved that the blue substance is a Phycocyanin much like the Cryptomonad 645 PC. (Fig. 4 ) Bohyslav Fott(1971) pointed out that the blue-green material was an intracellular "Cyanellen" as found in Gymnodinium aeruginosum. However, in the electronic microphotographs,...

Among the phytoplankton samples collected between May and June in 1979 from a high-yielding fish pond near the Yangtze River Bridge we have discovered a blue-green specimen of the genus Gymnodinium Absorption, fluorescence emission and excitation spectra have proved that the blue substance is a Phycocyanin much like the Cryptomonad 645 PC. (Fig. 4 ) Bohyslav Fott(1971) pointed out that the blue-green material was an intracellular "Cyanellen" as found in Gymnodinium aeruginosum. However, in the electronic microphotographs, so far no "Cyanellen" has been found except the lamellae structure in chloroplast which is the same as in phycocyanincontaining Cryptomond. The number of thylakoids per lamella is 2, the same as that in the chloroplast of Cryptophyta, but not the same as that in the Pyrrhophycophyta where the number is 3. (Fig. 20. C.D) Of the two kinds of nuclei one has the typical structure of dinocaryotic dinoflagellates and the other possesses some characteritsics typical of the nucleus of eucaryotic organisms. (Fig.14)The eucaryotic nucleus is surrounded by a double membrane but it seems to share another common membrane with the chloroplast which has its own envelope and might probably be endosymbiont as R. N, Tomas and Elenor R. Cox. (1973) reported. In both longitudineal and cross-sections,the cell appears to be of "Helianthus annuus-shaped" structure, which is quite similar to the contractile vacules of Paramoecium. The Mitochondria is very large whereas the Golgi apparatus is relatively small. As Gymnodinium eucyanochroum has some original characteristics,we believe that it is a transitional type in the algae evolution

本文报告了在南京发现的蓝色裸甲藻,测定了它的藻胆色素。证明蓝色藻胆蛋白不是山“胞内蓝藻”(Cyanellen)所提供。电子显微镜的扫描表明细胞表面有众多的突起,不是光滑的;横沟内的鞭毛不是“带状”而是由细纤维丝膜状物拉着的螺旋形。透视电子显微镜观察表明,该藻有两个类型的细胞核,即“甲藻核结构”(Dinocaryotic structure)和“真核结构”,(Eucaryotic Structure),真核与叶绿体有一个共同的膜的包被,有一个与原生动物相近似的伸缩泡系统。叶绿体是分枝状,在细胞的边缘位,但也有其它形态。有淀粉颗粒而无“造粉核”或称”“蛋白核”(Pyrenoid),多数位于叶绿体外或之间,类囊体与一般甲藻不同,不是三个排成一条“带”而是两个排列成“带”。有发达的线粒体,和高尔基体;鞭毛不论纵沟内的或横沟内的,其横切面,均为9+2的形式,其纵切面是由纤维丝成束的结构。蓝色色素提取物,可见光最大吸收峰为456nm,与隐藻藻胆色素十分相似。从细胞亚微结构及其色素性质,作者认为它是藻类演化过程中的一个中间类型的甲藻共生体。
