The facts that $PGE_2$ produced diuresis in the rabbit when given into a lateral ventricle of the brain and that $PGF_{2{\alpha}}$ is abundantly found in the brain prompted us to investigate the effects of $PGF_{2{\alpha}}$ introduced directly into the ventricle on the renal function. $PGF_{2{\alpha}}$ given intraventriculary in doses of $10{\mu}g\;and\;100{\mu}g$ elicited prompt diuresis, 10-fold increase of sodium excretion and two-fold increment of potassium excretion. Free water reabsorption also increased along with the increased osmolar clearance. Neither renal plasma flow nor glomerular filtration rate did change significantly. This, along with the fact that the percentage of reabsorbed sodium filtered decreased from 99.5 to 93.9, indicates the tubular site of the diuretic and natriuretic action. Atropine pretreatment did not influence the renal effects of intraventricular $PGF_{2{\alpha}}$. Intravenously administered $PGF_{2{\alpha}}$ in doses of 30 to $100{\mu}g$ did not produce any significant change in renal function. Intraventricular $PGF_{2{\alpha}}$ had no effect on the systemic blood pressure, whereas intravenous administration brought about a transient hypotension. These observations suggest that $PGF_{2{\alpha}}$ induces diuresis and natriuresis via central mechanism, that the site of the action resides in renal tubules, and that the reabsorption of sodium is inhibited in the proximal tubule, possibly through mediation of certain humoral agent. Overall, it is suggested that $PGF_{2{\alpha}}$ might play a roll in regulating renal function through the center.

G. japonicum is a perennial hem and the flowering plant has been used as a diuretic and an astringent in Japan and China. However, little information is available about the anti-inflammatory action of G. japonicum. Therefore, the objective of this study was to investigate the antiinflammatory action of fractions from G. japonicum methanol extract. Inhibition of NO production was observed when cells were cotreated with fractions of G. japonicum and lipopolysaccharide. We observed that ethyl acetate fraction of G. japonicum inhibited NO production by LPS-activated RAW 264.7 cells, and that the suppression induced by ethyl acetate fraction of G. japonicum was associated with antioxidant activity and direct NO clearance. In addition, only ethyl acetate fraction of G. japonicum inhibited stimulated $PGE_2,\;TNF-\alpha,\;IL-1\beta$ production, whereas water and methyl chloride fractions showed no such effects. The ethyl acetate fraction of G. japonicum methanol extract showed a remarkable scavenging activity on the 1,1-diphenyl-2 picrylhydrazyl radical. Based on the results, ethyl acetate fraction of G. japonicum may be useful source as natural antioxidants and antiinflammation. Therefore, the results obtained from this study provide an alternative protective mechanism of ethyl acetate fraction of G. japonicum and provide information on the potential use of ethyl acetate fraction of G. japonicum in chemoprevention or pathogenic conditions related to overproduction of NO and $PGE_2$. However, the mechanism of the inflammatory effect must be evaluated through various parameters for induction of NO production.

Hydrocortisone 5 mg/kg which exerts minimal effect on the renal function and furosemide 1 mg/kg which induces moderate amount of diuresis were injected intraperitoneally to study their effects on the renal cyclic nucleotides content in rats. 1) The renal tissue levels of cAMP were significantly increased by administration of hydrocortisone, but there was no significant change in the furosemide group compared with that of saline treated control group. Moderate elevation in renal cAMP level was noted by the combined administration of hydrocortisone and furosemide, but this elevation was less than that of hvdrocortisone treated group. 2) The renal cGMP level did not show nay remarkable change after the administration of hydrocortisone, however, there were a significant increase by the administration of furosemide alone or combination of both drugs. The level of renal cGMP was higher and maintained longer in the combined treated group than furosemide treated group. The result of this experiment indicates that the potentiating effect of hydrocortisone on the diuretic action of furosemide nay be related to the renal levels of cGMP rather than that of cAMP.

The effects of cinnarizine, $Ca^{2+}-antagonist$, on the antihypertensive effect of coadministered ${\beta}-blockers$, propranolol and metoprolol, were investigated in SHR. Drugs were coadministered orally for 4 weeks. Hemodynamic and biochemical changes induced by above drugs were determined to elucidate their mechanism of action. a) Cardiohypertropy of SHR was significantly improved by the treatment of ${\beta}-blockers$ as well as combination with cinnarizine and ${\beta}-blockers$. b) $Mg^{2+}-contents$ were increased in ventricle and decreased in plasma and aorta in all of the groups, especially in the group of propranolol with cinnarizine. c) c-GMP contents in ventricle were increased when cinnarizine was coadministered with propranolol, and c-GMP contents in aorta were increased when cinnarizine was coadministered with metoprolol, camparing with propranolol or metoprolol alone-treated group. d) Plasma renin activity appeared to be increased in cinnarizine treated alone, but reduced by combination with ${\beta}-blockers$. e) Triglycerides and $Na^+$ contents in serum were decreased in the group of metoprolol with cinnarizine, comparing with metoprolol alone-treated group. Increased $K^+\;and\;Ca^{2+}$excretions in urine by ${\beta}-blockers$ were inhibited by cinnarizine, so $Na^+/K^+$ excretion ratios were increased. Diuretic effects was showed in metoprolol alone treated group, but reduced when coadministered with cinnarizine.

Toad venom, 'Chan su' in Chinese and 'somso' in Korean, is a well-known traditional oriental medicine obtained from the skin venom gland of the toad. Formulations of toad venom have been widely applied in China, Japan, Korea and other oriental countries for a long time. It is often found in traditional Chinese formulations, such as Jiuxin (or Kyushin in Japan), Yixin, Huoxin, Shexiang baoxin wan, Lu shen wan and Laryngitis pills. According to a pharmaceutical chemistry study, toad venom contains multiple biological active substances, such as bufalin, resibufogenin and cinobufagin. Modern pharmacological studies indicated that toad venom has multiple pharmacological actions, including acting as a cardiotonic, antitumor local anesthetic effects, stimulates the respiratory center, vasopressor action, anti-inflammatory and diuretic effects. Like other medications, toad venom also has certain toxicity and adverse effects, for example, inducing delayed afterdepolarization and triggered arrhythmia. The major chemical constituents, basic pharmacological actions and adverse reactions of toad venom are discussed in this article.

중추의 ${\beta}-adrenoceptor$가 신장기능의 조절에 있어서 어떠한 역할을 하고 있는지를 알고자, 가토의 측뇌실내에 isoproterenol 및 propranolol을 투여하여 신장기능의 변동을 관찰하였다. Isoproterenol은 $5{\sim}50{\mu}g/kg$ i.c.v.의 범위에서 항이뇨작용을 나타냈으나 이는 주로 전신혈압하강에 따르는 신혈류 및 사구체여과율의 감소에 기인하며 세뇨관에서의 Na 재흡수억제효과는 음폐된 것으로 추론되었다. Propranolol $(500\;{\mu}g/kg\;i.c.v.)$은 신장기능에 현저한 변동을 초래하지 아니하였으나, propranolol후에 isoproterenol을 투여하면 전신혈압하강은 현저히 약화됨과 동시에, Na, K 배설의 증가와 신혈류의 증가, 그리고 뇨량증가경향이 관찰되었다. 즉, prapranolol에 의하여 isoproterenol의 강압작용은 영향을 받으나 신장작용은 영향받지 아니하고 현저하게 표현되었다. 본연구의 결과는, 중추의 ${\beta}-adrenoceptor$도 ${\alpha}-receptor$보다는 약하지만 신장기능의 조절에 있어서 어떤 역할을 하고 있음을 시사하였다.

The dried roots of Rehmannia glutinosa (RG) have been used in the traditional medicine for treatment of diabetes, fever and dysuria, etc. In order to investigate the quality evaluation of the dried roots of RG, we conducted the physico-chemical and biological evaluation method. The amount of catalpol from commercial samples is very diverse about $0.00{\sim}3.89%$ by using HPLC method, because it is easily decomposed by processing of RG. So, we should try to identify the correlation with the contents of catalpol and biological activities of RG. We chose 3 samples which were a wide difference of catalpol contents between each sample (Sample-I; 3.4%, Sample-II; 2.8%, Sample-III; 0.05%). Sample-I and Sample-II were found to be more effective than Sample-III on the DPPH free radical scavenging effect and inhibitory effect on $H_2O_2-catalyzed$ lipid peroxidation in rat liver in vitro. And, Sample-I and Sample-II exhibited more significant effects than Sample-III on accelerating actions of the small and large intestinal transport, and diuretic action in mice. So, it is suggested that the quantitative determination of catalpol should be required for the tandardization of the dried roots of RG.
