In anesthetised cats and dogs,sodium antim- ony tartrate,12 mg/Kg intravenously,could mark- edly diminish the intensity of the following circ- ulatory reflexes:the pressor reflexes on occlusion of the carotid artery and on injection of nicotine into the splenic vessels,the pressor and depressor effects on electric stimulation of the central stu- mp of the vagus (vago-sympathetic in dogs).On further analysis,it was found that the antimony compound did not significantly effect either the corresponding actions...

In anesthetised cats and dogs,sodium antim- ony tartrate,12 mg/Kg intravenously,could mark- edly diminish the intensity of the following circ- ulatory reflexes:the pressor reflexes on occlusion of the carotid artery and on injection of nicotine into the splenic vessels,the pressor and depressor effects on electric stimulation of the central stu- mp of the vagus (vago-sympathetic in dogs).On further analysis,it was found that the antimony compound did not significantly effect either the corresponding actions of the mediators including acetylcholine and adrenaline,or the transmission in the vagal and sympathetic ganglia and their peripheral endings.It was,therefore,most pro- bable that the antimony compound acted on cent- ral links in the reflex arcs of all these circulatory refllexes.In some of these,its depressant action on the liberation from the adrenals might also play an important role.

于麻醉犬猫进行实验,发现酒石酸锑钠12mg/Kg 静脉注射能显著减弱下列数种循环反射:夹颈动脉与脾臓血管内注入烟碱所致的升压反射,电刺激迷走神神向中段所致的升压反射与降压反射。进一步分析证明,锑剂并不影响植物神经介质乙醯胆碱与肾上腺素的有关作用,也不影响迷走神经节与交感神经节以及它们节后纤维末梢的传导。因此,锑剂在以上循环反射的反射弧中,最大可能即作用于其中枢环节,即有关的皮质下中枢,此外对于肾上腺髓质的抑制作用亦有重要的意义。

Liensinine, an alkaloid of the embryo loti, possesses a hypotensive activity of short duration, whereas the effects of its 2 quaternary ammonium salts are rather powerful and lasting. For O-methyl-liensinine methosulphate, the blocking effect on the ganglion of vagus nerve is more potent and durable than that on the superior cervical ganglion. Yet the vagi play no important role in its hypotension. Experiments on spinal cats and cross circulation of dog's head have demonstrated that the mechanism of action...

Liensinine, an alkaloid of the embryo loti, possesses a hypotensive activity of short duration, whereas the effects of its 2 quaternary ammonium salts are rather powerful and lasting. For O-methyl-liensinine methosulphate, the blocking effect on the ganglion of vagus nerve is more potent and durable than that on the superior cervical ganglion. Yet the vagi play no important role in its hypotension. Experiments on spinal cats and cross circulation of dog's head have demonstrated that the mechanism of action is mainly of peripheral, rather than central, origin. O-methyl-liensinine methobromide produces, likewise, a reduction of blood pressure in renal hypertensive dogs. The quaternary ammonium salts of liensinine differ from d-tubocurarine by one less ether linkage in chemical structure. Since liensinine is a novel typo of alkaloid, further study of its structure-activity relationship is of significance.

从蓮子心中提取出的莲心碱結晶,有短暫的降压作用。改变成季銨盐,就出現強而持久的降压作用。O-甲基-蓮心碱硫酸甲酯季銨盐对迷走神經节較对頸上交感神經节的阻滞作用为強而持久,但迷走神經在降压作用中不起主要作用。脊猫試驗与狗头交叉循环証明其降压机制主要是外周作用,而非中枢作用。 O-甲基-蓮心碱溴甲烷季銨盐对腎型高血压狗也有降压效能。莲心碱的季銨盐与箭毒块茎碱的化学結构不同,缺少一个氧醚鍵。因此莲心碱是一种新型的生物碱,深入研究其化学結构与疗效的关系是很有意义的。

The experiments were carried out in ten baby pigs at the age of 15-20 days with body weight of 1.5-3kg.The origin of the vagal preganglionic fibers of stomach wall was investigated by means of HRP techniques.100-200 μl of HRP solution was injected into gastric wall of each of these pigs.After 3 days,these baby pigs were slaugh- tered,their brainstems were treated according to O-D method(Edw- ards'79),and the labelled cells were identified with frozen serial sections.The results obtained are as follows: 1.The...

The experiments were carried out in ten baby pigs at the age of 15-20 days with body weight of 1.5-3kg.The origin of the vagal preganglionic fibers of stomach wall was investigated by means of HRP techniques.100-200 μl of HRP solution was injected into gastric wall of each of these pigs.After 3 days,these baby pigs were slaugh- tered,their brainstems were treated according to O-D method(Edw- ards'79),and the labelled cells were identified with frozen serial sections.The results obtained are as follows: 1.The HRP labelled cells were found evehly in the dorsal vagal nuclei of both sides in spite of injection sites and there was no evidence of asymmetry in distribution of HRP labelled cells. 2.The HRP labelled cells were present throughout the rostrocaudal extent of the dorsal vagal nucleus except for the ventrolateral border.After the injection of HRP into the wall of pyloric part, the labelled cells were found mainly in the medial aspects of the nucleus, although a few stippled cells were found in the lateral portion. 3.The number of the total labelled cells of the dorsal vagal nucleus, 17±7.3% was in the rostral region,41.4±5.6% in the rostromiddle region;26.8±7.2% in the caudomiddle region;and 14.8±5.3% in the caudal region. 4.A few labelled cells were observed in the area subpostrema. This finding is similar to the results of cholinesterase method and electrophysiological studies.Caudal to the level of obex,the labelled cells were not found in the medial solitary nucleus. 5.Except for the cases of pyloric injection,a cluster of labelled cells were observed in the intermediolateral nucleus of the first cervical segment of spinal cord,and a fewer-stippled labelled cells were found in the area between the intermediolateral nucleus and the central gray of Cl.In addition,in 2 pigs,some labelled cells were observed in the gray dorsal commissural nucleus of Cl. These results show that the vast majority of the preganglionic vagal fibers innervating the stomach arise from the dorsal vagal nucleus throughout its whole length,and most of them arise from the rostromiddle part of the nucleus at level above the obex.In addition, a few of them arise from the area subpostrema,and from the interme- diolateral nucleus and dorsal commisural nucleus of first cervical segment.

用 HRP 法逆行追踪了到胃壁去的迷走神经节前纤维的起源。将7~10%HRP100~200微升分点注入仔猪的胃壁,将脑干连续冰冻切片用邻联茴香胺绿色反应成色,置明视野显微镜下观察了标记神经元的分布。1.不分注射部分,HRP 标记细胞在两侧背迷核中大致呈对称性分布,而无一侧优势的存在。2.HRP 注射于全胃壁,标记细胞分布于背迷核除前中区和后中区外侧缘以外的全长范围内,尾端可延伸到第一颈髓。幽门部注射的标记细胞分布状况基本同全胃组,但幽门部标记细胞主要沿着核的内侧部分布,且在核的尾端无标记。3.背迷核中标记细胞,以前中区最多,后区最少。4.在各例胃壁注射 HRP 后,在闩和闩以上的亚极后区有零星的标记细胞,这与胆碱酯酶法和电生理学方法的结果相一致,在闩以下的孤束内侧核尾侧半未见标记细胞。5.除三例幽门部注射外,在第一颈髓的中间外侧核出现成簇的标记细胞,在中间外侧核与中央管之间的地带也有零星标记细胞,有两例在灰质背连合核出现标记细胞。这个结果未见文献报导。以上结果表明支配胃的迷走神经节前纤维起源于背迷核的全长,而以核的前中区最多。亚极后区、第一颈髓的中间外侧核、背连合核也发出少量迷走节前纤...
