  • This study was performed to elucidate the mechanism of antidiuretic action of diltiazem by infusion into the vein and carotid artery, of diuretic action into a renal artery in dog. Renal denervation caused a reversal of the effect of diltiazem from the antidiuretic to the diuretic when infused into vein or carotid artery, and potentiated the diuretic effect when infused into a renal artery. The changes of renal function in diuretic circumstances as described above included the increase in renal plasma flow, osmolar clearance, the amounts of sodium and potassium excreted in urine and the decrease in reabosrption rate of sodium and potassium in renal tubules. Above results suggest that antidiuretic action of diltiazem may be mediated by central nervous system, not by endogenous substance, diuretic action by direct renal action.

  • 저자는 적출관류 토끼 신장기능에서 칼슘의 역할과 furosemide의 이뇨작용에 미치는 영향을 관찰하여 다음과 같은 결과를 얻었다. hydralazine놔 verapamil을 주로 신혈관 저항의 감소로 이뇨작용을 나타냈다. furosemide를 hydralazine 또는 verapamil 병합투여시 뚜렷한 이뇨작용이 나타났으며 두군 사이에 차이는 없었다. quinidine은 신혈관 수축을 일으켰으나 이뇨작용이 나타났으며 furosemide의 이뇨작용을 항진시켰다. 칼슘제외된 관류액으로 관류시 칼슘은 신혈관 수축에도 불구하고 이뇨작용이 나타났으며 furosemide의 이뇨작용을 항진시켰다. quinidine은 칼슘이 제외된 상태에서 신장기능 및 furosemide의 이뇨작용에 영향을 미 치지 못하였으나 calcium 병합투여시 과도한 신혈관 수축으로 항 이뇨작용을 보였다. verapamil은 칼슘이 제외된 상태에서 약간의 이뇨작용을 보였지만 칼슘 및 furosemide의 이뇨작용을 변화시키지 못하였다. 이상의 성적은 적출관류 토끼 신장에서 칼슘, verapamil 및quinidine이 이뇨작용이 있으며 칼슘은 furosemide의 이뇨작용을 항진시킨다.

  • Objective : Diuretics are effective on the patients with hypertension and heart failure, as well as edema by regulating the function of kidney, which is key organ to maintain the balance of the different electrolytes in the body. The present review article is designed to review the diuretic effect of Korean medicinal prescription base on the experimental studies.Method : For this purpose, every article related to ‘diuresis’ and 'Korean medicinal prescription' were analysed from articles which published at domestic and international journals.Results : 1. Representative Korean medicine prescriptions showed diuretic effect along with electrolyte excretion were Oryeong-san, Paeryung-tang, Hwangryungbokryung-tang and Daeganghwal-tang. 2. Some Korean medicinal prescription including Oryeong-san, Jueryeong-tang, Sipcho-tang distribute diuresis through the inhibition of renin-angiotensin-system. 3. Oryeong-san, Bojungchiseup-tang had a diuretic effect on the down-regulation of aquaporin water channel in the renal collecting duct.Conclusion : Korean medicinal transcriptions have a diuretic effect through several types of mechanism such as along with electrolytes excretion, inhibition of renin-angiotensin system, and down-regulation of water channels.

  • Renal action of domperidone known as dopamine receptor blocker and effect of domperidone on renal function of dopamine were investigated in dog. Domperidone, when administered into vein, produced diuretic action by the improvement of renal hemodynamic state, when given into a renal artery, elicited diuretic action accompanied with natriuresis in only experimental kidney, whereas domperidone given into carotid artery exhibited antidiuretic action by the decrease of Na$^{+}$ excretion in urine. Diuretic action of dopamine was not influenced by domperidone given into vein or into a renal artery, was blocked by domperidone given into carotid artery. Above results suggest that domperidone produced both peripheral diuretic and central antidiuretic action, and domperidone do not block diuretic action by renal hemodynamic improvement of dopamine in kidney.

  • In the Indian traditional medicine, Lippia nodiflora (Verbenaceae) whole plant is claimed to possess powerful diuretic activity. However, the diuretic potential of this plant is not yet investigated. The aim of this study was to evaluate the diuretic potential of methanol extract of Lippia nodiflora (MELN) in rats. Control (0.9% saline solution, 25 ml/kg, b.w) or urea (1 g/kg b.w) or frusemide (5 mg/kg b.w) and different concentrations of MELN (200 and 400 mg/kg b.w) were intraperitoneally administered (n = 6 per each treatment group) to hydrated rats and their urine output was monitored over a period of 5 h and 24 h after drug administration. The diuretic responses with its electrolyte excretion potency of the extract were highly remarkable in comparison with control animals. The extract at doses of 200 and 400 mg/kg shows a significant increase in volume of urine with increase in $Na^{+}$, $Ca^{2+}$ and $Cl^{-}$ excretion accompanied by the excretion of $K^{+}$ in dose dependent manner. This study suggests that the active component(s) in MELN had similar diuretic effect to that of frusemide. These results validate the traditional use of Lippia nodiflora as a diuretic agent.

  • 심부전의 치료는 심방의 용적 과부하를 줄이기 위한 이뇨제, 심실 압력 과부하를 줄이기 위한 혈관확장제, 심근의 수축력을 향상시키기 위한 강심제 치료로 이루어진다. 이 중 이뇨제가 개의 심부전 조절에서 가장 중요하다. 하지만 장기간의 이뇨제 사용으로 급성 신부전이나 전해질 이상과 같은 부작용이 발생할 수 있다. 따라서 이 연구는 개에서 부작용이 적으면서 더 나은 이뇨효과를 가지는 생약성분의 이뇨제를 찾기 위해 설계되었다. 5마리의 건강한 개를 대상으로 한 예비실험에서 목통(Akebia quinata Decaisne) 추출물은 경도에서 중등도의 이뇨효과(furosemide 2 mg/kg 용량 효과의 0.3-0.5배의 효력)를 보였으며 혈청화학 수치와 전해질 변동은 거의 없었다. 실험 개체 수가 적고 기간이 충분하지 않지만 이 실험을 통해 심부전 환자에서 furosemide의 사용량을 줄이거나 대체할 수 있는 생약성분의 이뇨제 성분을 발굴하였다.

  • This study was performed to elucited the mechanisms of the antidiuretic action by SKP-450, a $K^+$ channel opener, given into the vein, and of the diuretic action observed only in the ipsilateral kidney, when given into a renal artery, in dog. The antidiuretic action of SKP-450 was not affected by renal denervation or pretreatment with glibenclamide, a ATP-dependent $K^+$ channel blocker. The diuretic action of SKP-450 was inhibited by renal denervation or pretreatment with glibenclamide. SKP-450 given into carotid artery had little effect on renal function. These results suggest that the antidiuretic action of SKP-450 given into the vein is caused by some endogenous substances probably not related to $K^+$ channel, whereas the diuretic action of SKP-450 observed only in ipsilateral kidney, when given into a renal artery, is provoked through $K^+$ channel related to renal nerves.

  • In order to determine the effect of Oryeongsan reputed to have diuretic action since Han Dynasty and possible synergetic action of Dianthi Semen, Polygonum avicularis Herba, Kochiae Fructus and Akebiae Lignum, herbs with similar reputation, when added to the above prescription, their decoction powders were solved into distilled water and injected into rabbits through the ear vein. Upon the treatment, the excretion of sodium, potassium and chloride ion together with urine volume was kinetically determined. At the same time the clearance of plasma creatinine and sodium ion was determined and the following results were obtained. Every experimental group demonstrated diuretic action, though feable, of relatively long duration. The diuretic mechanism in the case of Oryeongsan made up by mixing the seperate extracts of individual components and Oryeongsan(A) plus Dianthi Semen was found to be inhibitory effect of renal tubular reabsorption in contrast to the case of Oryeongsan(A) plus Polygonum avicularis Herba, Kochiae Fructus or Akebiae Lignum in which case the diuretic mechanism was found to be glomerular vascular dilatation. The urinary excretion of potassium ion was increased in the case of Oryeongsan(A) plus Dianthi Semen, Kochiae Fructus of Akebiae Lignum whereas in the other cases no similar change was registered. The diuretic action was most remarkable in the case of Oryeongsan(A) plus Polygonum avicularis Herba followed by Oryeongsan(A) plus Kochiae Fructus, Oryeongsan(A) plus Dianthi Semen, extract mixture of individual component of Oryeongsan, Oryeongsan(A) and Oryeongsan(A) plus Akebiae Lignum decreasing order. The duration of diuretic action was found to be 90 minutes in the case of Oryeongsan and mixture of individual component of Oryeongsan, and 60 minutes in the case of Oryeongsan(A) plus Dianthi Semen, Kochiae Fructus or Akebiae Lignum in contrast to the case of Oryeongsan(A) plus Polygonum avicularis Herba which lasted up to 120 minutes.

  • The diuretic action of guanethidine was investigated in the dogs by means of the stop-flow technique. Guanethidine increased the rejection of sodium in the ascending limb of Henle's loop, as well as in the proximal and distal tubules, resulting in the decrease of the concentrating ability of the kidney, in marked natriuresis and diuresis. It was also effective during an osomotic diuresis, which was induced by infusing 10% mannitol can exhibit its effect even under the diuretic action of mercurophylline, suggesting a different mechanism from that of mercuric iuretics.
