The toxicity of "76017" extracted from the fibrous root of San Chi [Panax rotoginseng (Burk) F. H.] was found to be rather low. Its LD_(50) in mice given intravenously was 836±17 mg/kg.Three to five minutes after intravenous injection of 76017 at the dosage of 25~50 mg/kg to open chest anesthetized cats the peak coronary flow was increased by 79% over the initial value. On the other hand, the blood pressure falled transiently, while the heart rate and oxygen comsumption decreased by 24.3% compared with the initial value.Experiments with Langendorff's rabbit heart showed that on the addition of 0.1~0.2 ml of 2% 76017 to the infusion system the peak coronary flow was increased by 17.5% and 48% respectively, the heart rate was slowed slightly and the contractile force enhanced by 48%.On adding 2% 76017 to the infusion system of isolated organ, the effluent flow from rabbit kidney, ear and hindlimb was found to be increased by 50%, 57% and 32% respectively at the small dosage of 0.1 ml and by 70%, 64% and 33% when the dosage was doubled.

三七绒根提取物(76017)为三七绒根乙醇提出物的有效成分,毒性较低,给小白鼠静注LD_(50)为836±17mg/kg。 给麻醉猫静注76017 25~50 mg/kg,3~5分钟内冠脉流量最高增加79%(P<0.05),血压呈暂时性下降,心率也略减慢,心肌耗氧量减少,比给药前平均降低24.3%(P<0.05)。 在家兔离体心脏灌流实验中,当2%76017 0.1和0.2ml注入灌流系统时,小剂量组给药后1分钟,冠脉流量平均增加17.5%;大剂量组给药后5分钟和7.5分钟分别增加48%和43%,(P<0.05),心率也稍减慢(P>0.05)。小剂量组心肌收缩振幅在5分钟内最高增加48%(P<0.05)。 在家兔离体器官血管灌流的实验中,当2%76017 0.1和0.2ml注入灌流系统,记录5分钟内的峰值,小剂量组兔肾、耳及后肢的流量分别增加50,57和32%;而大剂量组分别增加70,64和33%。

A total extract (named number 17) was isolated from the fibrous root of Panax notogienseng (Burk.) F H chen by the Yunnan Medicinal Institute. The present paper reports the experimental results of this extract on the heart.In perfused isolated hearts of guinea pigs, number 17 can increase the coronary blood flow, an increase of 84.04% on normal beating hearts was noted With an inotropic effect. However, no obvious change in heart rate was noted. The increase on fibrillating hearts reached only 65.06%. The decrease of coronary flow induced by pituitrin in beating hearts of guinea pigs was converted to an increase of 83.78% by perfusion of number 17.The blood flow of the coronary venous sinus was measured by an inserted pipe in open-chest dogs. Number 17 increased the coronary flow to 57.03% by injection into the duodenum and lasted for over 3 hours, associated with decrease of heart rate and fall of arterial blood pressure.Myocardial oxygen consumption was analysed by Roughton-Scholander method and calculated from blood samples withdrawn from the femoral artery and the coronary venous sinus. It was found that number 17 increased the myocardial oxygen consumption to 64.30%.The oxygen consumption of myocardial homogenate of rats was studied by Warburg's manometric method. When pyruvate was used as the substrate, number 17 inhibited the oxygen consumption but increase oxygen consumption if succinate was used as the substrate.According to Maroko's method, studies were carried out in anesthetized dogs. The S-T segment elevation on epicardial electrocardiogram was used as an index of myocardial ischemic injury on experimental coronary artery occlusion. The experimental results indicate that number 17 had no protection for myocardial ischemic injury, while propranolol protected it significantly.

三七绒根提取物“76017”(简称17号)按1∶20000的浓度加入灌流液中,能增加离体豚鼠心脏冠脉流量。搏动心脏用17号后,冠脉流量增加84.04%,同时心肌收缩力增强,但心率变化不大;在用垂体后叶素收缩冠脉的基础上,用17号灌流,冠脉流量增加83.78%;纤颤心脏用17号灌流,冠脉流量增加65.06%。 麻醉犬冠状静脉窦流出量测量。经十二指肠投予17号100mg/kg,冠脉流量增加57.03%,并能持续3小时以上,同时呈现心率减慢和血压降低。血氧测定结果,在冠脉流量增加高峰期,心肌耗氧量增加64.03%。 心肌匀浆耗氧量测定。0.1%的17号抑制以丙酮酸为底物之耗氧量,增加以琥珀酸为底物之耗氧量。 在实验性心肌梗塞模型上,静脉注入17号10mg/kg,未见到对心肌缺血性损害有保护作用,静脉注入心得安0.5 mg/kg,则有明显的保护作用。

The root hairs of seedlings of trifoliate orange(Poncirus trifoliataRaf.),citrange(P.trifoliataxCitrus sinensis),blood orange(C.sinensis(L)Osb.),‘Morocoo’sour orange(C.aurantium L.),‘lchang’bitterorange(C.ichangensis Swing.),‘Liangping’pummelo(C.grandis(L)Osb.),‘Egypt’rough lemon(C,jambhiri Lush.),‘Heping’92# tangerine(C.reticulata Blan.),and‘Santou’sour mandarine(C.reticulata Blan.)were observed by scanning electron microscope.Root hairs were found onthe fibrous roots of all observed Citrus species and hybrids.Somemorphological features about setting form,shape,density,length,anddiarneter of these root hairs are different from the species and hybrids.Of examined samples,‘Santou’sour mandarine,citrange,‘Egypt’roughlemon and‘Ichang’bitter orange have the best developmental root hairs.The results would be useful to the selection of Citrus rootstock etc.

利用扫描电镜观察了枣阳枳、南京枳橙、路比血橙、摩洛哥酸橙、宜昌橙、梁平柚、阿联粗柠檬、、汕头酸桔和和平92号红桔幼苗的根毛,发现这9种柑桔种和杂种的须根均有根毛,它们的着生方式、形状、密度、长度和直径等形态学特征依品种的不同而有所差异。其中,汕头酸桔、南京枳橙、阿联粗柠檬和宜昌橙的根毛最发达。上述结果可为柑桔砧木的选择、土壤管理等提供参考。
