Glomerular filtration rate (creatinine clearance) and renal blood flow (PAH clearance) were determined in dogs anesthetized with chloralose or Na-pentobarbital. In the control group (10 dogs), the renal hemodynamic effects did not show any significant changes in 2 hours. In the medicated group (10 dogs), after an intravenous injection of the alkaloid 0.25 mg/kg, there appeared a prompt hypotension, oliguria, a reduction of GFR and RBF, but no change in the glomerular filtration fraction. The renal vascular...

Glomerular filtration rate (creatinine clearance) and renal blood flow (PAH clearance) were determined in dogs anesthetized with chloralose or Na-pentobarbital. In the control group (10 dogs), the renal hemodynamic effects did not show any significant changes in 2 hours. In the medicated group (10 dogs), after an intravenous injection of the alkaloid 0.25 mg/kg, there appeared a prompt hypotension, oliguria, a reduction of GFR and RBF, but no change in the glomerular filtration fraction. The renal vascular resistance increased. Since these renal, hemodynamic alterations were found to be closely parallel to the modifications of blood pressure, they might also be a temporary depression secondary to the acute hypotension.

三氯醛糖或戊巴比妥钠麻醉狗,应用肾脏对肌酐及对氨基马尿酸的清除率测定其肾小球滤过率及肾血流量。对照组(10只狗)2小时内的肾脏血流动力学各项数值均无显著变化。给药组(10只狗)静脉注射蘿芙木硷0.25毫克/公斤后血压急速下降,尿量减少,肾小球滤过率及肾血流量均显著减低,但肾小球滤过部分则不变。肾血管阻力增大。以上变化于2小时后随血压之回升而恢复,降压较缓较弱者则变化不显著,因此这些现象也可能是血压骤降所继发的一种暂时性抑制。

Cardiac output was determined according to Fick's principle, while renaI blood flow (RBF) and glomerular filtration rate (GFR) were measured from the clearances of PAH and creatinine. One hour after an i.v. injection of guanethidine 5 mg/kg, normal dogs showed a very slight hypotension, which was relatively more noticeable in renal hypertensive dogs. The cardiac output, stroke volume, and ventricular work tended to decrease tn normotensive dogs, but tended to augment in hypertensive dogs. These alterations,...

Cardiac output was determined according to Fick's principle, while renaI blood flow (RBF) and glomerular filtration rate (GFR) were measured from the clearances of PAH and creatinine. One hour after an i.v. injection of guanethidine 5 mg/kg, normal dogs showed a very slight hypotension, which was relatively more noticeable in renal hypertensive dogs. The cardiac output, stroke volume, and ventricular work tended to decrease tn normotensive dogs, but tended to augment in hypertensive dogs. These alterations, however, were statistically insignificant. The total peripheral resistance was not much influenced by guanethidine in normal dogs, yet markedly diminished in hypertensive dogs. Diuresis was evident during the 1-hour postmedication period in both models. In hypertensive dogs, i.v. administrations of guanethidine caused a conspicuous rise of RBF and GFR, but a great reduction of the renal vascular resistance. In normal rats, following an i.p. injection of 20 mg/kg, the circulating blood volume (studied with I~(131)-labeled serum protein) exhibited a slight but non-significant increase within 3 hours, and returned to the original level at 24 hours. No significant change was found in DOCA-treated rats. Normal rats receiving guanethidine revealed an increase of blood volumes in all organs, especially spleen and kidney. These results demonstrate that the hypotensive action of guanethidine is not via the reduction of blood volume, but by way of a vasodilator action, which particularly amends the ischemic state of kidney and thus alleviates the pathologic process of renal hypertension.

本文用正常血压及腎型高血压狗研究胍乙啶对心和腎的血流动力作用,并用大白鼠試驗其对循环及器官血容量的影响。根据Fick氏原則測定心輸出量,同时从腎脏对于对氨基馬尿酸及肌酐的清除率計算腎血流量及腎小球滤过率。靜脉注射胍乙啶5毫克/公斤1小时后,正常狗血压略有降低,高血压狗降压則較为明显。胍乙啶对正常血压狗的心輸出量、心搏量及心室作功量有減 低的趋向,而对腎型高血压狗則略有增加,但均不显著。胍乙啶不影响正常狗的外周血管阻力,而能显著降低腎型高血压狗的总外周阻力,扩张其外周血管。注射胍乙啶后,正常血压及腎型高血压狗的尿量增加均非常显著。腎型高血压狗的腎小球滤过率及腎血流量都非常显著地低于正常狗,腎血管阻力則大大地高于正常狗,靜脉注射胍乙啶后,滤过率及血流量均明显增加,而血管阻力則大大降低。正常大白鼠腹腔注射胍乙啶20毫克/公斤后,3小时內循环血量略有增加,但不显著,6小时后开始恢复,2斗小时后回至原水平。对注射DOCA的大白鼠的循环血量則沒有明显影响。正常大白鼠注射胍乙啶后,各器官及組織內合血量普遍有增加趋势,其中以脾及腎的血容量增加最为明显,說明胍乙啶对这些部位的血管有扩张作用。上述資料証明:胍乙啶的降压作用并非通...

Renal clearances of creatinine and PAH have been studied in unanes- thetized well-trained normal and hypertensive female dogs. In the first series of experiments 0.2—1mg/kg of the alkaloid was administered intravenously to 5 normal dogs and effective RPF and GFR fell abruptly with the onset of hypotension which maintained for one to two hours.A steady fall of RPF continued for some time after the blood pressure resumed the control level.Possible causes of such effects are discussed. In the second series,the...

Renal clearances of creatinine and PAH have been studied in unanes- thetized well-trained normal and hypertensive female dogs. In the first series of experiments 0.2—1mg/kg of the alkaloid was administered intravenously to 5 normal dogs and effective RPF and GFR fell abruptly with the onset of hypotension which maintained for one to two hours.A steady fall of RPF continued for some time after the blood pressure resumed the control level.Possible causes of such effects are discussed. In the second series,the alkaloid,2—8mg/kg/day,was given orally to 5 hyper- tensive dogs for 10 days.The results showed that an increase of RPF occurred during the period in which the blood pressure significantly decreased;the GFR increased in some;whereas RBF and the glomerular filtration fraction remained unchanged.After discontinuance of medication the RPF and GFR as well as the blood pressure returned to the control levels.It appears that the effects of the alkaloid were quite similar to those of apresoline.

5只不麻醉正常狗的肾血浆流量(对氨基马尿酸清除率)和肾小球滤过率(肌酐清除率)分别为160(毫升/分)和44(毫升/分)。2只神经原型高血压狗肾血浆流量和肾小球滤过率分别为144和63。3只肾型高血压狗肾血浆流量和肾小球滤过率分别为110和44。神经原型狗或肾型狗的肾血浆流量,肾小球滤过率,肾血流量和肾小球滤过部分与正常狗相应比较时,并无显著差异。5只不麻醉正常狗静脉注射萝芙木碱0.2—1毫克/公斤后,在血压骤降期间内,肾小球滤过率及肾血浆流量等也都明显下降,在血压复原后1小时内肾小球滤过率增加,肾血浆流量降低。5只高血压狗每天口服萝芙木碱2—8毫克/公斤共10天,于血压显著下降后肾血浆流量(5只)和肾小球滤过率(3只)明显的增加,血球比容量(5只)则较给药前减低;停药后肾血浆流量,肾小球滤过率及血球比容量均恢复到给药前水平。在给药前后肾血浆流量和肾小球滤过部分无变化。
