  • The influence of guanethidine on the renal function was investigated in the rabbit. Guanethidine, 1-10mg/kg, i.v., produced no marked change in the renal function, while second and successive doses of guanethidine elicited a significant increase in urine flow and electrolyte excretion as well as renal plasma flow and glomerular filtration rate. It was suggested that the diuretic action was brought about by improvement of hemodynamic state in the kidney ; increased filtration as a result of increased renal perfusion. Atropine alone did not significantly influence the renal function but pretreatment of animals with atropine, 4 mg/kg i.v., completely abolished the diuretic action of guanethidine. It is suggested that guanethidine influences the renal function by activating parasympathetic nervous system or some cholinergic mechanism in the kidney.

  • Objectives : To establish objective and scientific evidence of Korean medicine (KM), the papers on Oryeong-san (Wuling-san) frequently used in medical institutions of Korean Medicine were analyzed. Methods : The papers were classified by the registration of domestic or international journals, the year of publication, experimental fields and the kinds of studies on biological activities. The therapeutic mechanism was investigated in accordance with therapeutic effect of Oryeong-san (Wuling-san). Results : Out of 57 articles selected, 16 were published in domestic journals, 17 were in Chinese journals and 24 were in Japanese journals. Most papers reported as biological activities were on improvement of renal function. Oryeong-san (Wuling-san) increased urine factor such as urine excretion and electrolyte balance while decreasing proteinuria, serum factors including creatinine, cholesterol and triglyceride. In addition, injured renal tissue was recovered normally and gene expression controlling urine excretion was down-regulated. Conclusions : Improvement of renal function could be interpreted as objective and scientific evidence for Oryeong-san (Wuling-san).

  • 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.

  • This case is to report the effect of renal function of chronic kidney disease(CKD) caused by IgA nephropathy. A 37-year-old man visited a Korean medicine hospital, who has been diagnosed with end stage renal disease(ESRD), 5 stage of CKD, caused by IgA nephropathy, has had no improvement of western medical treatment, and wanted to be treated using Korean medicine before renal transplantation. The decrease of creatinine value, the increase of glomerular filtration rate(GFR), and the decrease of CKD stage (5 to 4) was observed after combination treatment of Ikkigeonbiisuhwalhyeoltang and saam acupuncture was applied. This case report is suggested that combination treatment of acupuncture and herbal medicine could be effective to renal function of CKD in spite of a single case.

  • This study was performed in order to investigate the effect of nifedipine, a vasodilating drug which acts through calcium antagonism, on renal function using mongrel dog. Nifedipine, when given interavenously in doses ranging from 1.5 to 5.0$\mu\textrm{g}$/kg, elicited diuresis along with less changes of glomerular filtration rate and significant increases of renal plasma flow, so that the filtration fraction(FF) decreased significantly, at the same time both osmolar and free water clearances increased, and amount of sodium, potassium and calcium excreted in urine increased significantly. Nifedipine, when infused into a renal artery in doses from 0.05 to 0.15$\mu\textrm{g}$/kg/min, exhibited identical responses to the actions of intraveneous nifedipine except significant increase of glomerular filtration rate and no change of FF, which was confined only to the infused kidney. The renal action of nifedipine into a renal artery were not influenced by renal denervation, decreased significantly by ouabain, Na$^+$-K$^+$-ATPase inhibitor, which was given into a renal artery. Nifedipine infused into a renal artery in dog pretreated with propranolol i.v. produced diuresis associated with the increase of electrolytes excretion by reduction of electrolyte reabsorption and with no changes of glomerular filtration rate and renal plasma flow. Thus, it is concluded that nifedipine infused into a renal aretery produces diuretic action along with both improvement of hemodynamics and inhibition of electrolytes reabsorption, which may be related to sympathetic $\beta$-receptor or Na$^+$-K$^+$-ATPase activity because the action of nifedipine in kidney is blocked by propranolol or ouabain.

  • Renal failure means irreversible damage and depression of renal function, represented by glomerular filtration rate(GFR). A renal failure patient with uremia and anemia is presented. Anemia, in this patient, appeared before uremia did. A 55 year-old male patient was treated for renal failure with Weilingtang. Improvement was observed in, not only GFR, blood urea nitrogen(BUN), and creatinine, but also in such symptoms as difficulty in urine excretion, dyspepsia and abdominal swelling. But anemia appeared during treatment, so a mixture of Dangguibuxuetang(當歸補血湯) and Xiongguitang(芎歸湯) was prescribed. After this treatment, improvement in hemoglobin, and hematocrit was observed.

  • Verapamil, $Ca^{2+}$-channel blocker, when given into vein or into carotid artery, produced the decrease of urine flow accompanied with the decreased amounts of Na$^{+}$ and $K^{+}$ excreted in urine ($E_{Na}, E_{K}$) and with the decreased clearances of free water (C$_{H_2O}$) and osmolar substance (C$_{osm}$), and then increased reabsorption of Na$^{+}$ and $K^{+}$ in renal tubules (R$_{Na}$, R$_{N}$), glomeruler filtration rate (GFR) and renal plasma flow (RPF) were inhibited when verapamil was given into carotid artery, but were only tendency of reduction when given intravenously. Verapamil, when infused into a renal artery, exhibited diuresis accompanied with the increased GER, RPF, E$_{Na}$ and E$_{K}$, with the decreased filtration fraction (FF) in only infused kidney. At the same time, $C_{H_2O}$ was not changed, R$_{Na}$ and R$_{K}$ were reduced. Antidiuretic action by verapamil administered into vein or into carotid artery in normal kidney was reversed to diuretic action in denervated kidney. At this time, parameters of renal function exhibited the opposite phenomena compared to that elicited by verapamil in normal kidney, wherease renal denervation did not influence the action of verapamil infused into a renal artery. Above results suggest that verapamil produce both antidiuresis through nervous system centrally, not endogenous substances and diuresis by direct action in the kidney. Diurectic action are caused by hemodynamic improvement through dilatioon of vas efferense and by greatly inhibited reabsorption of electrolytes in distal tubules.

  • Purpose : We review our experience with pyeloplasty for unilateral ureteropelvic junction obstruction of moderate to severe hydronephrosis observed by prenatal ultrasonography to assess the appropriate timing of operation for recovery of renal function and obstruction. Methods : We retrospectively reviewed the records of the total 28 patients who underwent pyeloplasty between 1995 and 2001 at Asan Medical Center. We compared pre and postoperative differentials in renal function and diuretic renogram as measured by technetium-99m-mercaptoacetyl-triglycerine scan and the degree of hydronephrosis by renal ultrasonography. Results : In all 28 patients postoperative follow-up renal ultrasonography revealed significant improvement in hydronephrosis. In 10 poorly functioning hydronephrotic kidneys in which relative renal function function was less than 35%, renal function was improved postoperatively in 3 cases, but not improved in 7 cases. In all 28 patients postoperative follow-up diuretic renogram revealed significant improvement. Conclusion : We believe that the early pyeloplasty should be considered when ultrasonography and diuretic renography suggest obstruction because renal function does not improve significantly after pyeloplasty over preoperative value.

  • Background: Basiliximab is used as an alternative to tacrolimus in patients with decreased renal function. However, studies on basiliximab as a maintenance immunosuppressant, particularly in patients with lung transplantation, are limited. Therefore, here, we investigated the efficacy and safety of basiliximab in patients with lung transplantation. Methods: Adult patients with acute kidney injury (AKI) who received lung transplantation at a single general hospital between July 1, 2014 and June 30, 2018, were selected and classified in tacrolimus and basiliximab groups. Both groups received a triple-drug regimen (tacrolimus, mycophenolate mofetil, and steroids). However, tacrolimus was discontinued in the basiliximab group when AKI occurred, and two or more repeat basiliximab doses were administered within 3 months after transplantation. The electronic medical records were analyzed retrospectively. Results: Of the 85 patients who met the selection criteria, 61 and 24 were assigned to the tacrolimus and basiliximab groups, respectively. Significant improvement in renal function was observed in the basiliximab group (p <0.001). However, there were no differences in acute and chronic rejection rates in both the groups. No difference was observed in the incidence rate of complications between the groups, except for chronic kidney disease, which showed higher incidence in the basiliximab group (25.0% vs. 4.9%; p =0.013). Conclusions: We suggest the use of basiliximab as an immunosuppressant alternative to tacrolimus in patients with acute renal failure after lung transplantation. Basiliximab demonstrated effectiveness as an immunosuppressant and improved renal function. Therefore, basiliximab can be used in patients with decreased renal function.

  • Bilateral renal obstruction is a rare critical condition, requiring a prompt diagnostic approach and treatment to restore the renal function. The most commonly observed obstructive uropathy in children is congenital malformation, such as posterior urethral valves and bilateral ureteropelvic junction obstruction. Malignant pelvic masses obstructing the ureter are widely reported in adults but are rarely observed in children. The treatment of ureteral obstruction related to pelvic malignancy is a therapeutic challenge with a median survival duration of 3-7 months in adults; however, pediatric patients with pelvic malignancy leading to ureteral obstruction had better outcomes, with a reported 5-year mortality rate of 20%, than the adult patients. Here, we report a rare case of bilateral ureteral obstruction associated with pelvic rhabdomyosarcoma presenting with acute kidney injury treated by ureteral diversion with double J stent, and concommittent emergency hemodialysis, leading to restoration of good renal function. We suggest that bilateral ureteral obstruction should be released as soon as possible using surgical or interventional approach to minimize the obstruction period, and subsequential chemotherapy may contribute to improvement of survival and recovery of renal function.
