The subcutaneous administration of sodium dimercaptosuccinate (SDS) at a dose of 1500 mg/kg immediately after the intraperitoneal injection of trivalent antimonyl ammonium gluconate (AAG) increased the LD_(50) of the latter from 90—112 mg/kg to 1300—1460 mg/kg. The acute toxicity of the latter when injected intravenously in rabbits was also decreased when SDS was administered via the same route. Two hours after the intravenous injection of AAG (containing radioactive antimony) in rabbits, high radioactivity...

The subcutaneous administration of sodium dimercaptosuccinate (SDS) at a dose of 1500 mg/kg immediately after the intraperitoneal injection of trivalent antimonyl ammonium gluconate (AAG) increased the LD_(50) of the latter from 90—112 mg/kg to 1300—1460 mg/kg. The acute toxicity of the latter when injected intravenously in rabbits was also decreased when SDS was administered via the same route. Two hours after the intravenous injection of AAG (containing radioactive antimony) in rabbits, high radioactivity level was found in the liver. The levels in the spleen and the thyroid were very low. Intravenous administration of SDS immediately after the antimonyl decreased the radioactivity level in the liver. Fifteen minutes after the AAG injection, plasma radioactivity was 1.4—1.6 times the radioactivity in the blood cells. When SDS was also administered, the plasma level was 3.4—27.4 times as high as the level in the cells. Kidney was found to be the main route of excretion of antimony in rabbits. When SDS was used after AAG, about 96% of the administered dose of antimony was excreted in 72 hours, whereas only 36% was excreted in the same period if AAG was administered without SDS.

皮下注射二巯基丁二酸钠1500毫克/千克,司将小鼠一次腹腔注射锑铵的半数致死量从90—112毫克/千克提高至1300—1460毫克/千克。静脈注身锑~(124)铵予家兔後,如立刻经同一途径注射二巯基丁二酸钠,亦可降低锑铵的急性毒性。二巯基丁二酸钠的解毒机制为阻止血锑进入组织,减少锑在部分组织中的含量及增加锑自尿排泄的速度。锑主要自尿排出,用二巯基丁二酸钠後,72小时内锑由尿排出给药量的96%,而对照组动物在同时间内仅有36%由尿排出。

The changes of the calcium flux in the anterior byssus retractor muscle of Mytilus edulis duringcontraction and contracture have been observed with the aid of radioactive calcium. After previousloading with Ca~(45), stimulation of the muscle either by 50 cycles alternating current or by directcurrent increased the outlux of Ca~(45). With the muscle in sea water containing Ca~(45), the influxof the radioactive element was also increased during contraction produced by electrical stimulationas well...

The changes of the calcium flux in the anterior byssus retractor muscle of Mytilus edulis duringcontraction and contracture have been observed with the aid of radioactive calcium. After previousloading with Ca~(45), stimulation of the muscle either by 50 cycles alternating current or by directcurrent increased the outlux of Ca~(45). With the muscle in sea water containing Ca~(45), the influxof the radioactive element was also increased during contraction produced by electrical stimulationas well as during potassium and acetylcholine contracture. In all cases, more vigorous or prolongedcontraction or contracture was associated with a more marked increase of the calcium flux.Although the increase of the outflux during a prolonged contracture became rather irregular in itstime course, it tended to persist throughout the contracture. These findings are in keeping withthe view that calcium probably plays a role in the coupling between excitation and contraction.

贻贝前足丝收缩肌在直流电或交流电刺激引起收缩时,纤维钙的外向通量和内向通量都增高,其程度和收缩的大小有平行关系。用氧化钾或乙酰胆碱引起肌肉挛缩时,纤维钙的内向通量也增高。从这些结果来看,贻贝肌肉的收缩或挛缩和钙可能有密切的关系。

Nearly one-third of the life history of winter wheat is spent in the winter. Therefore, the condition under which the plants pass over their “over-wintering” stage has a great deal to do with the yield next year. Important as the “over-wintering” stage is, little is known about the physiology of the plant during that period.The present paper summarizes our four-year work on the physiology of wheat root during the winter season. It was found that during the winter season, while the above-ground part of the plant nearly died down, the root kept on growing at a considerable rate. From December to February, its length increased by two feet. During the winter, the root maintained rather a high rate of respiration and its enzymatic activities, including activities of catalase, diastase and phosphorylase, were measurable. When supplied with P32-labelled phosphate solution in various ways, the root showed ability not only to absorb the phosphate ions, but also to transport them to the above-ground organs. The radioactivity, instead of distributing uniformly throughout the different organs, maintained some physiological gradient, indicating that the P32 did not enter the plant by mechanical force, but was physiologically absorbed.The techniques concerning the application of radioactive tracers under field conditions were also summarized and discussed.

1.在越冬期间小麦的根系并不停止生长。根据1958—1959年的观察,从12月初至2月初这610余天中,根系生长了2尺以上。 2.越冬期间的根系能够将施入土壤中的(NH_4)_2SO_4转化为氨基酸。 3.根系在越冬期间具有相当显著的呼吸活动,其过氧化氢酶、转化酶和磷酸化酶都是可以测出的。 4.当向介质中施入含有P~(32)的磷酸盐溶液时,在12小时内(没有在更短的时间取样)P~(32)遍及于植株全体,P~(32)在各器官中的分布表现出明显的生理陡度,说明P~(32)的进入植物体确系由于生理吸收,而非机械吸收。 5.对于在田间条件下应用同位素研究越冬期间根系的生理活动进行了总结和讨论。
