Ascorbic acid has been used in treatment and prevention of hypo-or avitaminosis C as well as in many other clinical conditions including some cardiovascular diseases. The intravenous injection of large doses of Injectio acidi ascorbici (IAA) (pH=5.6) was known to be effective in the management of cardiogenic shock in Kershan disease. The present paper reports the experimental results on the effect of IAA on blood pressure, hearts, and blood vessels with a view to elucidating certain mechanisms of its efficacy in cardiogenic shock. In urethan-or Na-pentobarbital-anaesthetized dogs, rabbits, and cats, an intravenous injection of IAA at the dosage of 0.2, 0.4 g/kg moderately and temporarily raised the arterial blood pressure to the extent of about 10—20 mm Hg, lasting about 5—10 minutes. No significant change in heart rate was observed, but during the early phase of the elevation of blood pressure the respiration became quickened and deepened. As the blood pressure of animals was reduced below 80 mm Hg by operation and haemorrhage or various hypotensive drugs (chlorpromazine, sodium nitrite, histamine, papaverine), the pressor effect was more pronounced and sustained than that in anaesthetized animals. Solutio acidi ascorbic (SAA) always produced a drop of blood pressure, but after being neutralized with sodium bicarbonate to pH=5.6, it could exert the same pressor effect as IAA. It seemed, therefore, that the pressor effect of IAA was due to the partially neutralized ascorbic acid in it. Cardiac output, was estimated on Fick's principle in urethan-anaesthetized dogs, an intravenous injection of IAA 0.2 g/kg increased the cardiac output, cardiac index, stroke volume, and aortic mean pressure, especially in hypotensive animals. The total peripheral resistance was not obviously altered. In using IAA (1:500, 1:1000), both the contractile amplitude of Cushny's rabbit's heart in situ and of isolated rabbit's heart were enlarged; at the same time, heart rate and coronary flow of the latter were also increased. In perfused isolated rabbit's ears, hind legs, and kidneys, IAA (1:500, 1:1000) showed no remarkable effect, except a slight dilatation. During the rise of blood pressure after IAA administration, the blood flow of hind leg and kidney by Kaverina's method was increased. IAA slightly increased the spleen volume of anaesthetized dogs, while SAA always diminished it. From these results, the pressor effect of IAA seemed to be chiefly due to the improvement of cardiac function, resulting in an increase of cardiac output. It was considered that IAA might serve as an effective drug in combating cardiogenic shocks other than those in Kershan disease.

本文报导大量抗坏血酸注射液(injectio acidi ascorbici,以下簡称IAA)对动物血压、心脏及血管的影响。IAA为用碳酸氫鈉中和的10%抗坏血酸灭菌溶液,pH約为5.6,內加焦亚硫酸鈉作稳定剂。靜脉注射IAA 0.2克/公斤及0.4克/公斤可使麻醉犬、猫和家冤动脉血压輕度短时上升;在因手术創伤、失血及数种降压莉物(氯丙嗪、亚硝酸鈉、組織胺、罌粟碱)所致低血压的动物,IAA的升压作用較为明显持久。同剂量抗坏血酸溶液(solution acidiascorbici,以下簡称SAA)靜脉注射常引起血压下降,用碳酸氫鈉将SAA中和后即有升压作用,焦亚硫酸鈉无升压作用,故IAA的升压作用是中和后的抗坏血酸所引起。靜脉注射IAA0.2克/公斤可增加麻醉犬心搏量、心輸出量及心脏指数,对总外周阻力无明显影响;对在体冤心亦呈現兴奋作用。1:1,000和1:500的IAA灌流离体冤心后,可見心縮振幅加大,心率略增,冠脉流量增多。IAA对离体冤耳、腎、下肢血管无明显影响。在体冤下肢及腎血管血流量在血压上升时均有增加。犬脾容积在IAA注射后有輕度扩张現象,而SAA却使脾容积短时減少。实驗結果表明,IAA的升压作用主...

The cardiotonic potency and therapeutic range of corchoroside A were compared with the well-known cardiac glycosides in heart-lung preparations of guinea pigs and cats. Heart failure was produced by adding pentobarbital sodium to the blood in the venous reservoir of heart-lung preparations (HLP) at a uniform rate (1mg/minute) in most experiments. In some other experiments the preparations were allowed to deteriorate spontaneously.A Steady fall in the cardiac output and right atrial pressure rise was taken as an indication of failure. The cardiac Competence test was used to assess the cardiac function by raising the venous reservoir by 5~10 cm for 15 seconds.The reduction in atrial pressure and the increased cardiac output were taken as an indicator of "threapeutic dose". Following the appearance of therapeutic effects the continued infusion of a cardiac glycoside results in cardiac irregularities. These irregularities are accompanied by a progressive reduction in the cardiac output and a concomitant abrupt rise in atrial pressure with widened pulse waves. These phenomena mentioned above were taken as an indicator of "toxic dose". Further continuation of the infusion results in ventricular fibrillation and was taken as an indicator of "lethal dose".The ratios of the threapeutic dose and toxic dose to the lethal dose in three glycosides have been expressed in per cent of the dose respectively. In the HLP of cats corchoroside A usually yielded higher therapeutic effect than ouabain and strophanthin K. In the HLP of guinea pigs its therapeutic dose was similar with ouabain and higher than strophantin K. Corchoraside A not only improved cardiac function and increased cardiac competence but the manifestation of cardiotonic action was earlier.Under our experimental conditions in the HLP of guinea pigs the per centage ratio of therapeutic dose/lethal dose was 6.05 for corchoroside A, 17.45 for ouabain, 14.41 for strophanthin K and in the HLP of cats 10.86, 21.29, and 22.96 respectively. Hence, corchoroside A has a 2~3 fold greater "safety margin" than the other two glycosides studied. It is statistically significant, The utilization of the HLP of guinea pigs as a novel tool for the determination of the therapeutic range of cardiac glycosides is also discussed.

本文报告强心药黄麻甲甙的治疗作用强度、治疗宽度并与已知强心药作比较性研究。在豚鼠、猫心肺制备上,以戊巴比妥钠引起心力衰竭(少数自发性心力衰竭),分别测定了黄麻甲甙、哇巴因、康毗丁的治疗作用及治疗宽度,以输出量或静脉压的改善作为、“治疗量”的指标;以静脉压重又上升,波幅加大,心律不齐作为“中毒量”指标;以发生心室纤维颤动作为“致死量”指标;计算了三种药物的治疗量/致死量、中毒量/致死量的百分率,黄麻甲甙在二种心肺制备上,对心力衰竭有良好的治疗作用,其治疗量在猫身上小于哇巴因;在豚鼠身上则与哇巴因相近,不仅作用较强,而且作用较其他二种已知强心甙发生得更早。 在治疗量/致死量的百分率方面,在豚鼠心肺制备上,黄麻甲甙为6.05%、哇巴因17.45%、康毗丁14.41%。在猫心肺制备上则分别为10.86%、21.29%及22.96%;即黄麻甲甙的治疗宽度为上述二种强心甙的2~3倍,在统计学上有显著性差异。在中毒量/致死量的百分率方面,三种强心甙差异不大。本文对豚鼠心肺制备的实验方法及其作为测定强心甙治疗宽度的工具,作了简短的讨论。

From 1961 to 1978, 40 cases of intrathoracic terato-dermoids were operated upon in Capital Hospital, among which 10 cases of giant tumors were analyzed. The diameters of all these 10 tumors exceeded 17 cm. and the cystic content of the largest one amounted to 5,000 ml.The thorax is one of the most common locations of giant terato-dermoids, because the inner lining of the cyst secretes sebaceous material, mucin or cerebrospinal fluid continuously, and the large intrathoracic space is fa- vourable to continual growth of the tumor. The incidence of complications of the intrathoracic giant terato-dermoids is very high, and these complications modify the clinical picture of the terato-dermoids. For a successful operation, the importance of improving pulmonary and cardiac function before operation and minimizing surgical trauma is emphasized. In patients with poor general conditions, tumors of extremely large size may be resected by stages.
