  • The direct effect of isoproterenol on renal function, when given intravenously, is usually obscured by its potent hypotensive action. To obviate the latter action, isoproterenol was infused directly into one renal artery of the dog, the other kidney serving as a control for the general action. And following results were obtained. In the first series of experiments, the directic action of isoproterenol was ascertained. $1.0\;{\mu}g/kg/min$. reduced on both kidneys the urine flow, clearances of PAH and creatinine, as well as the amount of sodium excreted, but the effect was weaker on the experimental side than on contralateral side. With $0.1\;{\mu}g/kg/min$., two cases among 6 experiments showed marked diuresis, two cases no apparent effect, and another two marked antidiuresis on the experimental kidney, whereas the contralateral kidney exhibited antidiuresis in all cases. Further reducing the dose unmasked the diuretic action on the ,experimental kidney. In another series, the effects of isoproterenol on the blood flow distribution within the kidney and on sodium concentration gradient within the kidney tissue were observed. $0.05\;{\mu}g/kg/min$ isoproterenol markedly increased the medullary plasma flow and slightly increased total renal plasma flow and glomerular filtration rate, along with concomitant increase in the amount of sodium excreted and osmolar clearance, and decrease in reabsorption of free water. Sodium concentration gradient markedly decreased in the experimental kidney, reaching 2/3 of the value observed in the contralateral kidney at the papilla. It is thus concluded that isoproterenol exerts a diuretic action, when infused directly into a renal artery, and the mechanism of the action rests on its hemodynamic action, substantiated as the increase in glomerular filtration and in the medullary blood flow, resulting in washout of hyperosmolality produced by the coutercurrent multiplier system.

  • The fruit of Actinidia arguta (AA) has been used mainly for the treatment of skin diseases, diuresis, diabetes mellitus and osteoporosis in Korean traditional medicine. It is known that AA (hardy kiwi) fruit extract has an effect on 2-chloro-1,3,5-trinitrobenzene-induced atopic dermatitis-like skin lesions in NC/Nga mice. Mode of action for it is associated with the modulation of biphasic Th1/Th2 cytokines. Furthermore, DA9102 containing AA is a herbal medicine currently under phase II clinical trial for atopic dermatitis in Korea. However, no active principles of AA on the decrease of Th2 cytokines including IL-4 and IL-10 have been identified. In this study, bioactivity-guided fractionation of an alcohol extract from the dried fruits of AA using ELISA assay for IL-4 production led to the isolation of $\alpha$-linolenic acid (I), linoleic acid (II), ethyl linolenate (III), ethyl linoleate (IV) and ethyl stearate (V) as the major active components. These compounds showed the down-regulatory effects of IL-4 production in A23187-stimulated RBL-2H3 cells without cytotoxicity.

  • Phytolaccae Radix (PR), Brunella Herba (BH), Akebiae Lignum (AL) and Atractylis Rhizoma (AR) are some of the diuretic agents used in Chinese medicine and folk remedy. Water or methanol extracts of them (100mg/kg) were intravenously injected to rabbits in order to re-evaluate the effects on renal function. PR water extract elicited moderate diuresis while water extracts of BH, AL and methanol extract of AR had antidiuretic effects. Influence of PR on renal hemodynamics and $Na^+-K^+$-ATPase activity in rabbit kidney were observed in vivo and in vitro. The results were as follows: 1) Clearances of inulin and p-aminohippuric acid increased significantly after 15 minutes following the administration of PR water extract, but Na+ reabsorption rate was not changed. 2) The increase of $Na^+-K^+$-ATPase activity in renal cortex, outer and inner medulla was observed at 15 minutes after PR water fraction was given intravenously, and the change was most prominent in cortical area. 3) More than 50% of decrease in $Na^+-K^+$-ATPase activity in renal tissues was observed with PR water fraction $(10^{-2}g/ml)$ in vitro experiments. However, the inhibition of $Na^+-K^+$-ATPase activity was reversed with lower concentrations $(10^{-4}g/ml,\;10^{-6}g/ml)$ of PR water fraction in outer and inner medullary zone. These results suggest the diuretic effect of PR is due to improved renal hemodynamics, and contradictory reults concerning $Na^+-K^+$-ATPase activity require further investigation.

  • We arrived at the following conclusion after we have studied crohn's disease through the literatures of western and oriental medicine. 1. Crohn's disease has a characteristic of granulomatous necrosis and cicatricial inflammation which is called by segmental enteritis, granulomatous enteritis. This falls under the category of "Diarrhea", "Dysentery" and is similar to "small intestinal diarrhea", "acute temesmus", "splenic diarrhea" in oriental medicine. 2. In western medicine, the cause of crohn's disease indefinites, but it is presumed immunological unbalance of alimentary canal. In oriental medicine, it is summarized as the abnormal ascending and descending circulation of stomach and splenic energies, the hepatic stagnation, being the lower part of cleaning qi by exogenous disease, dyspeptic convulsion. 3. The presenting symptoms of crohn's disease are intermittent chronic diarrhea, fever, weight loss, abdominal spastic pain or abdominal discomfort. When anyone has a abdominal mass, a rectal abcess, and a rectal constriction by physical examination, we can doubt crohn's disease. 4. The methods of western medical treatment are a suppression of intestinal toxic contents and inflammatory mediator, a supply of nutritive substanceus to intestinal epithelial cell. Oriental medical treatments of these are "inducing diuresis", "warming kidney to reinforce yang", "nourishing qi to invigorate spleen", "eliminatin dampness by cooling" according to syndrome differentiations. As mentioned above, we can confirm possibility of oriental medical treatment that induces recovery of immunologic control function and we need advanced experiment, study, and clinical approach.

  • Hantavirus pulmonary syndrome(HPS) is a systemic disease that is caused by a newly discorved and characterized virus of the Hantavirus genus, which is most frequently referred to as the sin nombre virus. The clinical syndrome resembles other hantavirus syndromes worldwide, except that it is characterized by a brief prodromal illness followed by rapidly progressive, noncardiogenic edema, and that it is more deadly than any previously recognized hantavirus infection. The clinical manifestations of HPS are characterized by four clinical phases : prodrome, pulmonary edema and shock, diuresis, and convalescence. Mortality is greatest in the first 24 hours of the pulmonary edema and shock phase of the illness. These phases are strikingly similar to the clinical phases of Hemorrhagic fever with renal syndrome(HFRS) induced by Hantaan virus, except that HPS has not been associated with renal failure and Disseminated intravascular coagulation(DIC). We here report a case of hantavirus pulmonary syndrome developed in a 58 year-old man. He had a flu-like illness followed by the rapid onset of respiratory failure due to noncardiogenic pulmonary edema. HPS was diagnosed by clinical manifestations, identification of high titer antibody to Hantaan virus antigen and histologic finding of transbronchial lung biopsy (TBLB) specimen. The patient was treated with mechanical ventilation and initial corticosteroid pulse therapy resulting in successful outcome.

  • Eurya emarginata (Thunb.) Makino (Theaceae) is distributed in coastal areas of island. The leaves of Eurya are used in the traditional medicine of the coastal areas of jeju island with the aim of diuresis or to treat ulcers. Nevertheless, there are few reports on the biological activity and constituents of E. emarginata. In this study, we investigated the pharmacological activity of the solvent extracts of E. emarginata on the several inflammatory markers (TNF-$\alpha$, IL-1$\beta$, IL-6, NO, iNOS and COX-2). Also we examined the antioxidizing effect of the solvent extracts by determination of DPPH radical-scavenging activity. Among the solvent fractions, EtOAc and BuOH extracts showed potent radical scavenging activity (RC$_{50}$=10.9 and 12.7 respectively). The subtractions of EF 5-4-6-3-2 and BF 1 potentially inhibited the mRNA expression of pro-inflammatory cytokines (IL-1$\beta$, IL-6 and TNF-$\alpha$) at the concentration of 100 $\mu\textrm{g}$/mι. Also the fractions inhibited the mRNA expression of pro-inflammatory cytokines (IL-1$\beta$, IL-6 and TNF-$\alpha$) and protein expression of iNOS and COX-2 at the concentration of 100 $\mu\textrm{g}$/mι. And then, the inhibition of iNOS was correlated with the decrease of nitrite level. These results suggest that E. emarginata may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines, iNOS and COX-2.2.

  • Renal dysfunction is a common complication of open-heart surgery: a form of controlled hemorrhagic shock, and successful perioperative management of renal dysfunction depends on recognition of the risk factors and optimal management of factors influencing renal function, including cardiopulmonary bypass, and early detection of renal failure. Changes in renal functional parameters including Ccr, Cosm, CH2O, FENa, and RFI were observed prospectively in forty five patients operated on at Dept. of Thoracic and Cardiovascular Surgery, S.N.U.H., from April to June, 1985. They were 23 males and 22 females with 35 acquired and 10 congenital heart diseases and the mean age and body surface area of them were 38.010.3 years [22-63] and 1.5518 M2[1.151.92] respectively. Followings are the conclusion. 1. The Ccr, representative of renal function, is significantly improved from 90.231.3 ml/min/M2 preoperatively to 101.536.4 ml/min/M2 postoperative and day [P<0.05], and all patients were classified as postoperative renal functional class I of Abel, which representing adequate renal protection during our cardiopulmonary bypass. 2. The Cosm is significantly elevated at immediate postperfusion time and remained high at postoperative one day representing osmotic diuresis at that time, but CH2O shows no significant changes at immediate postperfusion period and is decreased significantly at postoperative one day, representing recovery of renal concentrating ability at that time with decreasing urine flow. 3. The absolute value and changing tendency in FENa and RFI during perioperative period shows no diagnostic reliability on these parameters, but those of CH2O appear to reveal future renal function more accurately than Ccr 4. The depth of hypothermia may be protective upon renal function against the ill effects of prolonged nonpulsatile cardiopulmonary bypass. 5. The depth of the hypothermia, pump time of more than 150 minutes, poor cardiac function, and intraoperative events such as embolism appear to be related with immediate postperfusion renal function. 6. Hemoglobinuria and hemolysis, poor preoperative renal function, history of cardiac surgery, and massive transfusion associated with bleeding appear not to be related with renal dysfunction.
