    4-Methyl-5-ethyl-2-thiouracil reacts with ethyl bromide in alcoholic solution in presence of sodium ethylate,forming 2-ethylmercapto-4-methyl-5-ethyl-uracil(m. p.141°),from which 2-ethylmercapto-4-methyl-5-ethyl-6-chloropyrimidine,boiling at 148-150° at 13 mm.,at 164-166° at 17 mm.,or at 180-185° at 25 mm.,is prepared according to the directions given by Johnson and Bailey.This chloro- pyrimidine reacts with sodium methylate in methyl alcohol forming 2-ethyl- mercapto-4-methyl-5-ethyl-6-methoxypyrimidine,boiling at 152-154° at 11 mm., at 156-160° at 16.5 mm.,or at 162° at 22 mm.,and with sodium ethylate in ethyl alcohol forming 2-ethylmercapto-4-methyl-5-ethyl-6-ethoxypyrimidide,boiling at 139-140° at 5 mm.or 142-145° at 7 mm. 2-Ethylmercapto-4-methyl-5-ethyl-6-methoxypyrimidine interacts with chlorine with formation of 2-ethylsulfonyl-4-methyl-5-ethyl-6-methoxypyrimidine,m.p.45- 47°,in a yield of 81% of the theory.2-Ethylmercapto-4-methyl-5-ethyl-6-ethoxy- pyrimidine interacts with chlorine with formation of 2-ethylsulfonyl-4-methyl-5- ethyl-6-ethoxypyrimidine,boiling at 202-205° at 5 mm.or at 212-215° at 10 mm.,in a yield of 91% of the theory.2-Ethyl-mercapto-4-methyl-5-ethyl-6- chloro-pyrimidine interacts with chlorine with formation of 2-ethylsulfonyl-4- methyl-5-ethyl-6-chloro-pyrimidine,m.p.74-75.5°,in a nearly quantitative yield. 2-Ethylsulfonyl-4-methyl-5-ethyl-6-chloro-pyrimidine reacts with sodium methy- late in methyl alcohol,producing 4-methyl-5-ethyl-2,6-dimethoxypyrimidine,boil- ing at 123° at 15 mm.or 113-115° at 11 mm.;while 2-ethylsulfonyl-4-methyl- 5-ethyl-6-methoxypyrimidine reacts with sodium methylate in methyl alcohol, producing the same pyrimidine-dimethyl ether,boiling at 123° at 17 mm.2- Ethylsulfonyl-4-methyl-5-ethyl-6-ethoxy-pyrimidine reacts with sodium ethylate in ethyl alcohol in an analogous manner to form 4-methyl-5-ethyl-2,6-diethoxypyri- midine,which boils at 130° at 8 mm.4-Methyl-5-ethyl-6-methoxy-uracil,m.p. 194-195°,is produced by boiling 2-ethylsulfonyl-4-methyl-5-ethyl-6-methoxypyri- midine with 10% sodium hydroxide solution.Likewise,4-methyl-5-ethyl-6-ethoxy- uracil,m.p.179-180°,is produced by boiling 2-ethylsulfonyl-4-methyl-5-ethyl- 6-ethoxypyrimidine with 10% sodium hydroxide solution.The action of alcoho- lic ammonia upon 2-ethylsulfonyl-4-methyl-5-ethyl-6-chloropyrimidine at 100—105° gives 2-ethylsulfonyl-4-methyl-5-ethyl-6-aminopyrimidine,melting at 108—109°. 4-Methyl-5-ethyl-cytosine,m.p.296-298° or m.p.294°,is formed (i) by boiling 2-ethylsulfonyl-4-methyl-5-ethyl-6-amino-pyrimidine with 6 N hydrochloric acid and (ii) by heating 4-methyl-5-ethyl-6-methoxy-uracil with alcoholic am- monia at 120-140° for 18 hours.Thus,there are two new routes for synthesiz- ing 4-methyl-5-ethyl-cytosine,starting from 2-ethylmercapto-4-methyl-5-ethyl- uracil.Although these new methods involve one or two steps more than the old method described by Johnson and Bailey,who heated 2-ethylmercapto-4-me- thyl-5-ethyl-6-chloropyrimidine with alcoholic ammonia,producing the correspond- ing mercaptoaminopyrimidine,from which the ethylmercapto-group was removed by boiling with hydrochloric acid,they appear to be unique.

    In an attempt to ascertain an effective schistosomi cidal regime with tartar emetic,we de- vised an animal experiment of two steps:first,to obtain an optimal initial big dose which would cause the adult worms to shift from mesenteric vessels toward the liver and secondl,to obtain an optimal maintenance dose which would prevente the worms from moving back from the portal radicals.The experiment was carried out as follows: (1)Rabbits each infected with 100 cercariae of Schistosoma Japonicum were divided into three groups and doses of tartar emetic 8 mg/kg/day were administered intravenously for 1,2 and 3 days respectively.The hepatic shifts of worms in three groups were found to be 74.0%, 93.5% and 98.0% respectively. (2)At first the maintenance dosage was determined by calculating the amount of drug excreted in the urine and stool on the second day.Then we gave this amount,double and triple of it to three different groups of rabbits and each group was further divided into 3 sub-groups which received the maintenance dose for 3,5 and 7 days respectively. It was found that the retaining rate of the worms was inversely proportional to the main- tenance dosage and the length of the course.Comparatively satisfactory results were obtained in groups which received 8 mg/kg for two days followed by a maintenance dose triple the amount excreted on the second day for 3 or 5 days.

    1.本文报告锑钾治疗家兔血吸虫病的剂量与疗程的探求。首先探求促使成虫大量向肝转移时所需有效剂量,继则探求控制成虫不能向肠复位时所需有效剂量与日程。2.锑钾每日按体重每公斤8毫克,分别注射1,2,3天,停药1天后肝内成虫检出率分别74.1%,93.5%,与98.0%。3.在锑钾每日按体重每公斤8毫克连续二日后,继以第2天锑排泄量(相当于锑钾1.62毫克/每公斤体重)的1,2,3倍,分别维持3,5,7天。结果成虫残余率与维持的剂量大小及日程长短成反比。4.根据这次动物实验结果,以锑钾每日按体重每公斤8毫克注射两天,继以维持第2天锑排泄量的三倍,连续3-5天治疗家兔血吸虫病,可以获得比较满意的结果。

    (1) Activities due to various neural structures in the lateral geniculate body of the cat were studied by means of glass capillary microelectrode. These structures are the presynaptic axon and various parts of the postsynaptic neuron. Aside from the usual forms of the response of these structures, less usual forms were described.

    (1) Activities due to various neural structures in the lateral geniculate body of the cat were studied by means of glass capillary microelectrode. These structures are the presynaptic axon and various parts of the postsynaptic neuron. Aside from the usual forms of the response of these structures, less usual forms were described. Single and repetitive stimulations of the optic nerve by electrical shocks were employed as a means of differentiating pre- and post-synaptic response. (2) In substantiating a view expressed by some workers, further evidence has been adduced to indicate that activity due to a single optic nerve fibre is capable of initiating postsynaptic discharge. However, the readiness of different neurones to fire upon the arrival of impulses from the optic tract is quite variable. In general, this variability is due not so much to the smallness of excitatory synaptic potential initiated as to the condition imposed by the mixed action of both excitatory and inhibitory input. (3) Two steps in the generation of the postsynaptic spike could be dissociated by experiment using two antidromic shocks. This offers a direct proof that the two steps are respectively generated by the initial segment of the axon and the neuron soma proper.

    (一)本工作采用玻璃微电极分析了猫外膝体神經結构的电活动。一般說,突触前軸突和突触后神經原不同部分的活动,均有一定的特性,不难加以区別,但是对某些少見的情况,单个或重复电刺激祝神經仍然不失为有效的鉴別突触前和突触后活动的手段。 (二)本文提供了实驗,說明单根祝神經紆維的传入冲动,就其本身所引起的突触电位大小而言,足以引起突触后神經原发放,但是实际上能否引起突触后传导的反应,对不同的神經原和在不同的情况,有很大的差別。这些差別,主要是由于兴奋性和抑制性輸入同时作用的結果。 (三)外膝体神經原峯电位的两个成分能用二个逆行刺激的方法加以分离,这表明它們是分別在軸丘和細胞体发生的。
