The receptive relaxation of the stomach has been observed on esophageal and gastric fistula dogs following distension of the esophagus by means of a small balloon. The results were as follows: (1) Reflex relaxation of the stomach co(?)ld be induced readily by distending the esophagus. The threshold of such a stimulus has been determined to be 4-6 cc of air and the latent period, 3-5 seconds. This threshold value was not always strong enough to bring about concomitantly a secondary peristaltic wave. Thus, the relaxation of the stomach is not a result of the secondary peristaltic wave in the esophagus. (2) That the integrity of both vagi in the neck is necessary for inducing the above mentioned phenomenon has been confirmed in this work in dogs by applying parasympathetic blocking drugs or after bilateral vagotomy. (3) By using the receptive relaxation reflex of the stomach as a basis, artificial conditioned reflex has been established with the sound of an electric bell or a metronome as indifferent stimulus. The formation of the conditioned reflex seemed to be fairly easy as evidenced by the fact that after about 40 times of combination, a definite conditioned reflex of the relaxation of the stomach appeared and after about 60 combinations, it became more distinct.

本实验用具有食道瘘和胃瘘的狗,利用小氣球擴张食道的方法,进一步观察引起胃容受性舒张的条件,结果如下: (一)机械地扩张食道可迅速引起胃的容受性舒张,食道扩张刺激的阈值是4—6毫升,潜伏期是3—5秒。此阈值并不能经常同时引起食道二级蠕动波。因此,胃的容受性舒张的产生似不取决於食道的二级蠕动波。 (二)注射抑制副交感神经药物或切断颈部迷走神经後,刺激食道即不再能引起胃的容受性舒张反射。因此,在狗体上和猫体上一样,颈部迷走神经的完整是产生胃的容受性舒张所必需的。 (三)用食道扩张刺激为基础,以电铃声或节拍器聲作为条件刺激,可形成胃容受性舒张的条件反射。在结合四十余次後,即出现条件反射;在结合六十余次後,条件反射性的胃的容受性舒张则甚明显。

A series of 8 new compounds with the dithia-dihydrostibiol structure has been compared for the therapeutic activities against schistosomiasis japonica in white mice. Each drug, thoroughly mixed with the finely powdered food, was fed to healthy mice for 14 days, and the LD_(10) and LD_(50) were evaluated. At the dosages of LD_(10) and LD_(50), each drug was fed to treat diseased mice (beginning on the 36th day after percutaneous infection on abdomen with 40 cercariae per mouse) for 14...

A series of 8 new compounds with the dithia-dihydrostibiol structure has been compared for the therapeutic activities against schistosomiasis japonica in white mice. Each drug, thoroughly mixed with the finely powdered food, was fed to healthy mice for 14 days, and the LD_(10) and LD_(50) were evaluated. At the dosages of LD_(10) and LD_(50), each drug was fed to treat diseased mice (beginning on the 36th day after percutaneous infection on abdomen with 40 cercariae per mouse) for 14 days. After a holding period of another 14 days mice were killed. Both portal system and liver were carefully scrutinized for worms. Basing on the average number of worms remained in each mouse, the therapeutic effects of out of the 8 compounds were better than that of tartar emetic administered orally.

用小白鼠试验8种二硫锑五环化合物,在同一毒性水平上比较对於日本血吸虫病的疗效。每种药物与饲料粉混匀喂饲健康小鼠14天,求出LD_(10)及LD_(50)。以这两个剂量,分别治疗病鼠(每鼠腹部皮肤感染40条尾蚴,5周後开始给药)14天,然後停药14天解剖,详细检查门静脉系统与肝内的余存虫。根据平均每鼠余存虫数,以吐酒石为标准,比较各药的疗效。结果发现Sb-1及Sb-19口服疗效较吐酒石为优。

Acute toxicity experiment consisted of one single intraperitoneal injection, while subacute toxicity experiment consisted of one injection daily for 14 days, of tartar emetic and a subsequent 3-day holding period. The mortality of mice from tartar emetic was observed after concomitant injections of 5 testing drugs (procaine-HCl, sodium phenyl acetate, sodium α α'-dimercaptoadipate, sodium mercaptosuccinate and sodium thiosulfate).

Acute toxicity experiment consisted of one single intraperitoneal injection, while subacute toxicity experiment consisted of one injection daily for 14 days, of tartar emetic and a subsequent 3-day holding period. The mortality of mice from tartar emetic was observed after concomitant injections of 5 testing drugs (procaine-HCl, sodium phenyl acetate, sodium α α'-dimercaptoadipate, sodium mercaptosuccinate and sodium thiosulfate). The effective detoxicants were mixed up with tartar emetic and then injected intraperitoneally, once daily for 14 days, to infected mice. The mice were killed after a holding period of another 14 days. Basing on the average number of worms remained in each mouse, the effects of detoxicants on the antibilharzial activity of tartar emetic were compared. The results were as follows: (1) In mice the acute and subacute LD_(50) after intraperitoneal injection of tartar emetic were found to be 38 and 35 mg/kg/day respectively. (2) The mortality of mice from tartar emetic could be markedly reduced by simultaneous injection of procaine, sodium phenyl acetate, sodium α α'-dimercaptoadipate and sodium mercaptosuccinate, while sodium thiosulfate did not afford any protection. (3) Procaine, sodium phenyl acetate, sodium α α'-dimercaptoadipate and sodium mercaptosuccinate did not decrease the therapeutic. activity of tartar emetic, and, moreover, procaine could significantly augment its therapeutic activity against schistosomiasis japonica.

本文叙述了5种药物(盐酸普鲁卡因、苯乙酸钠、aa′-二巯基己二酸钠、巯基丁二酸钠及硫代硫酸钠)对小白鼠腹腔注射吐酒石急性(注射1次,观察3天)及亚急性(注射14天,观察3天)中毒死亡的影响;并将其中有效解毒药分别和吐酒石混合後腹腔注射小鼠14天以治疗日本血吸虫病,然後停药14天解剖,根据平均每鼠余存虫数比较各药对於吐酒石疗效的影响。结果如下: (一)小白鼠腹腔注射吐酒石急性及亚急性LD_(50)分别为38及35毫克/千克/天。 (二)普鲁卡因、苯乙酸钠、aa′-二巯基己二酸钠及巯基丁二酸钠能使小鼠腹腔注射吐酒石急性及亚急性中毒死亡率明显地减低,而硫代硫酸钠则无效。 (三)普鲁卡因、苯乙酸钠、aa′-二巯基己二酸钠及巯基丁二酸钠4种解毒药并不减低吐酒石之疗效,其中普鲁卡因尚能提高吐酒石治疗日本血吸虫病之疗效。
