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.

Controlled crosses made between apple×pear(P.communis,P.serotina,P. Bretchneideri,P.ussuriensis),apple×plum,apple×cherry,apple×peach(P.pe- rsica,p.Davidii),apple×apricot,and apple×strawberry from 1953 to 1955 have proved that hybrid seeds can be obtained even between sub-families,except the strawberry.The percentage of fruit setting varied with the remoteness of the phylogenetical relation befween female and male parents,ie.apple×pear higher than apple×stone fruits.For different varieties of apple under different natural and agricultural conditions gave different results,it is suggested that in order to obtain hybrid seeds several maternal varieties should be used in two or three conti- nuous years. Seeds obtained from mixed pollination method(a limited quantity of pollen grains of an apple variety applied to the stigma 4 hours after the proceeding dis- tant cross)were most probably not true hybrid seeds.It seems necessary to length- en the time interval between the two operations of pollination. Pollination with old stigma(6 days after emasculation)reduced the percentage of fruit setting in apple×pear,and it seemed to have some positive effect in app- le×stone fruits.The percentage of fruit setting was greatly increased in appee× pear by using trees which had been prelimiuarily vegetative-approached as maternal parents,as compared with ordinary cross. The seedlings of distant hydrid,especially those individuals with parental or new characteristics,grew very feebly and soon perished with gradual.browing and drying of the root system.

一、用一般的套袋授粉法进行苹果和梨、和核果类桃、李、樱桃、山杏、山毛桃等组合的有性杂交可以获得杂交果实和种子。二、杂交的结实率因父本的种类而不同,苹果和梨(仁果类)杂交结实率、结种子率一般较苹果和桃、李、樱桃等核果类为大。三、母本苹果不同品种不同的自然及栽培条件下成功的可能性不同。因此在进行远缘杂交时应同时选几个品种作为母本,在不同年份连续进行较易获得成功。四、先授以远缘花粉隔四小时后再授以限量近缘花粉的混合授粉法所得结果不可靠。是否用延长间隔时间或采用丧失发芽力的近缘花粉的混合授粉法以促进杂交结实而不致引起差误有待于进一步研究。五、用去雄后6天进行授粉的衰老柱头授粉法,似不宜用于一般杂交结实尚不很困难的苹果和梨之间的杂交,但用于苹果和某些核果类果树之间的杂交似有促进作用。六、以父本种类作砧木对母本进行教养影响的无性渐近杂交法显著地提高了苹果和梨远缘杂交的结实率。七、远缘杂种生活力弱,幼苗甚易夭折,一般从茎的基部或地下部分开始变褐,渐渐全株枯死。杂种部分植株表现父本梨或全新性状,表现这些性状的植株生活力尤为衰弱。如何克服杂种幼苗的夭折尚待继续研究。

In dogs under pentothal anaesthesia it was found that the submaxillary gland usually showed spontaneous secretion and that pressure stimulation of the carotid sinus by the inverted venous sac method augmented such secretion. The augmenting response persisted after sectioning either the chorda tympani or the vagosympathetic nerves.

In dogs under pentothal anaesthesia it was found that the submaxillary gland usually showed spontaneous secretion and that pressure stimulation of the carotid sinus by the inverted venous sac method augmented such secretion. The augmenting response persisted after sectioning either the chorda tympani or the vagosympathetic nerves. After sectioning of both nerves the response disappeared in some animals, but still persisted, though to a lesser extent, in other animals. In the latter animals the response could finally be abolished by dividing the soft tissue on the medial aspect of the gland. The mechanism of this phenomenon is still not clear. Pressure stimulation of the carotid sinus has been found to augment the motility of the urinary bladder, when the anaesthesia used was very light. Only in a very few instances, inhibition of motility was observed. The efferent pathway of the augmenting response seems to be located in the sacral parasympathetic, for it was abolished by either administration of atropine or low level transection of the spinal cord. Intestinal motility has been found to be stimulated in the carotid sinus reflex, when the intestinal tone was initially low. With a high initial motility, however, the response might be an inhibition. In still other experiments no response from the intestine could be observed. Our results indicate that, under light anaesthesia pressoreceptive impulses from the carotid sinus may irradiate widely in the vegetative nerve centers so as to affect salivary secretion and intestinal and urinary bladder motility, the end result depending on the functional state of the nerve centers and also of the effectors themselves at the time of stimulation.

(一)在硫贲妥钠浅麻醉下犬的颌下腺多半有自动性分泌。颈动脉窦内加压一般都可以反射地刺激颌下腺的这种分泌。这一反射的传出途径除由腺门进入腺体的鼓索神经和交感神经外,可能尚有新的通路,文中曾予讨论。 (二)在浅麻醉或清醒状态下,颈动脉窦内压力增加可以反射地刺激膀胱运动,或是发动膀胱收缩,或是增加膀胱的收缩强度、收缩频率与收缩持续的时间。这一反射的传出途径通过盆神经。在个别情况下,也看到有抑制膀胱节律性活动的作用。 (三)颈动脉窦内压力增加也可以反射地刺激各段小肠以及结肠的运动,能够提高其紧张性,节律性与收缩强度。如果肠的运动性较高,有时则能发生抑制效应。 (四)我们认为颈动脉窦压力感受性反射在植物神经系统中能广泛扩散,尤其在浅麻醉或清醒状态下最容易表现出来,并且一般是副交感性的。
