Acetylcholine(I;X=OH,n=1)is a substance possessing intense physiological activity toward the vegetative nerves.It would be interesting to see the variation of physiological activity in the homologous series of choline esters(I). C_nH_(2n+1)·CO·OCH_2·CH_2·N~+(CH_3)_3X~- (I) The literature methods for the preparation of choline esters either by the interaction of β-halogen-substituted ethyl esters with trimethylamine or by the acylation of choline salts are not satisfactory in the purification of the products. Loury prepared a few choline ester salts by the acylation of 2-dimethylaminoetha- nol and the subsequent quaternization of the tertiary amines so obtained,but he did not give the details including the physical constants and the analyses of the products.In the present work this method has been extended,a series of fatty acid esters of choline iodide has been synthesized.The products are well-defined crystalline solids.The lower members of the series are soluble in water,methanol or ethanol;the higher members are only slightly soluble,and the solid substances are greasy and the solutions are soap-like.The higher members gave two melting points,heating to high temperature caused the decomposition of these compounds, trimethylamine hydroiodide was isolated in several cases. When these compounds were used on the isolated rabbits' heart the lower members produced an acetylcholine-like effect,i.e.a slowing of the heart rate, the octanoyl compound was more or less inactive,and from then onwards with increasing chain-length an increasing degree of inhibition of the response to acetyl- choline was produced.From the decanoyl compound onwards with increasing chain length they inhibited spontaneous gastric secretion and the secretion of the vagotomised stomach stimulated by prostigmine in the rats as well if administered intramuscularly.

(1) In 12 apparently healthy monkeys, the average respiratory rate was 46/minute, heart rate 227/minute, systolic/diastolic pressures 155/123 mm Hg, rectal temperature 39.0℃, erythrocytes 5.3 millionscu mm, leukocytes 15700 cu mm, among which lymphocytes 50.8%, neutrophils 45.0%, monocytes 2.0%, eosinophils 1.6%, and basophils 0.6%. (2) Sb-11 (H_2O_3Sb SCH_2COONa) is a pentavalent antimonial salt of stibonic acid. Intravenous injections at the daily dosage of 10 mg/kg in monkeys for 3 or 6 weeks produced no cough, nausea, vomiting, anorexia or other reactions. Likewise, Sb-11 had no significant influence on the respiration, blood pressure, EXG, temperature, and the blood cell counts. (3) Five monkeys were each infected with 300 cercariae of Schistosoma japonicum. Beginning on the 43rd day after the infection, Sb-11 was given intravenously on 3 monkeys at the dosage of 10 mg/kg/day for 3 weeks. The remaining 2 monkeys served as control. After a holding period of another 4 weeks, the monkeys were autopsied. The numbers of the helminths remained in the 3 monkeys of the medicated group were 0, 1 and 13 respectively, with the schistosomes all degenerated, while those of the control group were 81 and 138 respectively. So the therapeutic effect of Sb-11 was vory remarkable. (4) The toxicity of Sb-11 was rather low. Drug tolerance to Sb-11 developed quickly in monkeys; which showed no toxic manifestations after a course as long as 6 weeks. Hence Sb-11 is recommended to be tried clinically on those patients who cannot receive intensive treatment of tartar emetic.

(一) 12只正常猴子平均呼吸頻率为46次/分,心跳为227次/分,收縮壓/舒張壓为155/12s毫米汞柱,體溫为39.0℃。平均紅血球5.3百萬/立方毫米,白血球15.7千/立方毫米,其中淋巴球50.8%,嗜中性45.0%,單核球2.0%,嗜酸性1.6%及嗜鹼性0.6%。 (二) Sb-11(H_2O_3Sb-SCH_2COONa)是5價之(月弟)酸鹽。猴子靜脈每天10毫克/千克,共3週或6週,無咳嗽、噁心嘔吐及食量減少等毒性反應,且對呼吸,血壓、心電圖、體溫及血球數等也無顯著影響。 (三) 5猴各感染日本血吸蟲尾蚴300條,其中2猴不给藥作對照,3猴自感染後第43天開始治療,劑量10毫克/千克/天,療程3週,停藥4週後解剖。對照组2猴各餘存蟲81與138條;治療組8猴分別餘存蟲0,1與13條,蟲體萎縮,所以療效非常顯著。 (四) Sb-11毒性低,對猴子能產生耐藥性,療程延長至6週亦無毒性表現。所以我們建議,臨床上吐酒石短程療法禁忌的病人,可試用Sb-11。

This research was carried out in two parts: Part I: Experiments on normal animals: 1, Two sets of female rats, one in estrus and one in dioestrus, were used. Antimony potassium tartrate (tartar emetic, T.E.) was injected intraperitoneally for each rat of the two sets in a dose of 42mg/kg. The mortality rate of the "estrus" set was 68%, while that of the other set was 92%. The difference is significant. The survival time of the former set was also longer than the latter. 2. T.E. was injected intraperitoneally...

This research was carried out in two parts: Part I: Experiments on normal animals: 1, Two sets of female rats, one in estrus and one in dioestrus, were used. Antimony potassium tartrate (tartar emetic, T.E.) was injected intraperitoneally for each rat of the two sets in a dose of 42mg/kg. The mortality rate of the "estrus" set was 68%, while that of the other set was 92%. The difference is significant. The survival time of the former set was also longer than the latter. 2. T.E. was injected intraperitoneally to rats and mice in the usual dioetrus period, but 30 hours before the injections, large doses of sex hormones were given intramuscularly to both groups of the animals used. (a) The mortality of the control group (rats) was 80-90%, while that of the group previously protected by testosterone or by Diethylstilbestrol (DES) combined with progesterone was significantly lowered. (b) The mortality of the control group (mice) was 50%, while that of the group previously protected by DES or testosterone or by DES combined with progesterone was also significantly lowered. (c) When the "dioestrus" rats and mice were substituted by the "estrus" rats and mice, no protective action could be found by any sex hormone in the rats, while for mice, the protective action was similar to that obtained in the "dioestrus" group. The results of experiments 1 and 2 lead to the conclusion that: Sex hormones have definite protective action against the high mortality rate of T.E. intoxication in animals with iow sex hormone level. 3. The effect of DES upon the toxicity of large doses of T.E. in mice was studied by electro cardiographic method. It was found that, both in experimental and control groups, T.E. caused a marked decrease in heart rate and a considerable lengthening of PQ interval. DES did not reduce the final mortality of large doses of T.E., it did exhibit, however, a statistically significant death delaying action. DES seemed to have a refraining action, though statistically not significant, on the prolongation of PQ interval caused by T.E. Part Ⅱ: Experiments on animals artificiallyinfected with Schistoma japonica. DES, administered to female white mice artificially infected with schistosoma japonica, did not reduce significantly the toxicity of T.E. The reason why DES caused a reduction of toxicity of T.E. in the normal animals (rats and mice), and not in the morbid ones was briefly discussed,

本研究分两个阶段进行。第一阶段应用正常动物。第二阶段应用病理动物。第一阶段:正常动物试验,分三部分: 1.动情期及动情间期二组雌性大白鼠,分别腹腔注射锑剂42mg/kg,中毒死亡率分别为68%及92%,二组间差异显著,前组死亡鼠之活存时间也见延长。 2.动情间期雌性大白鼠或小白鼠,于腹腔注射锑剂前30小时,分别肌肉注射性激素。 (1)对照组动物(大白鼠)死亡率为80~90%左右。预先给予睾丸素或己烯雌酚与黄体酮合用的受保护组死亡率明显降低。 (2)对照组动物(小白鼠)死亡率为50%左右。预先给予己烯雌酚,睾丸素或己烯雌酚与黄体酮合用的受保护组死亡率均明显降低。 (3)改用动情期雌性大白鼠及小白鼠结果:性激素对大白鼠未见保护作用,而对小白鼠之保护作用与动情间期小白鼠组相同。以上结果指出,机体性激素水平低时,锑剂中毒死亡率提高;性激素对锑剂中毒有一定的保护作用。 3.用雌性健康小白鼠,腹腔注射大剂量的吐酒石。一组为对照组,另一组事先注射雌性激素,作为实验组。两组均作心电试验。结果显示,不论在对照组或在实验组,吐酒石引起心率大大下降及心电PQ间隔延长。己烯雌酚未能防止动物死亡,但却有明显的推迟死亡的作用,此外尚能缓...
