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.

Houttuynia cordata Thunb.[H.cordata]belonging to Saururaceae, is a wild medicinal herb of perennial plants, and grows well in a place with a lot of shade and moisture. The medical action of H.cordata is reported to have an antitumer effect, toxicity-suppressive effect, antifungal effect, diuretic effect, and antioxidative action, but its effect hasn't been reported on cardiovascular diseases, such as ateriosclerosis and hypertension yet. This study intended to confirm the effect of the water extract of H.cordata on the migration and proliferation of rat aortic smooth muscle cells. Such results show that the water extract of H.cordata suppresses the migration and proliferation of rat aortic smooth muscle cells. It is believed that a useful clue will be offered later to the prevention of cardiovascular diseases such as ateriosclerosis and hypertension, and the development of their medicines on the basis of the fact.

In this study attemps were made to obtain evidence as to the action of Mori Radicis Cortex on the renal' function of anesthetized mongrel dogs. 1. A light brown powder isolated from Mori Radicis Cortex (MRC) by a slight modification of Tanemura's method, when given intravenously in doses ranging 0.5 to 5.0mg/kg, elicited diuresis with the increase of positive water clearance and amounts of $Na^{+}$ and $K^{+}$ excreted in the urine. At this time the glomerular filtration rate, renal plasma flow and osmolar clearance were not observed to have any significant changes. This diuresis was augmented in process of time and its maximum effect was exhibited about 30 minutes after administration of MRC. 2. The MRC, when administered into a intra carotid artery, responded promptly with diuresis and natriuresis at a level too small to effect renal functions when administered intravenously. In this experiment the patterns of changes of renal function were the patterns of changes of renal function were the same as those of the above intravenously administered experiment. 3. When infused directly into a renal artery, the MRC exhibited little effect on either kidney. 4. During water diuresis, the MRC did not elicit diuretic action or significant changes in renal functions. The above observations suggest that the diuresis of MRC is brought about by the inhibition of the release of antidiuretic hormone with the mechanism facilitating the excretion of $Na^{+/}$ and $K^{+}$ in urine.

The Unani System of Medicine (USM) is one of the traditional systems of medicine that deals with plants. Plants are large source of medicine. JIRJEER (Eruca sativa) is one of the plant origin drugs, has been used for various therapeutic purposes in USM. It contains Erucic acid (major contain), oleic acid, linoleic acid, saturated Fatty acids, Flavonoids, Phenolics, Glucosinolate, Vitamin C and Carotenoids. These active constituents are responsible for their actions described in Unani classical literature such as Muqqawwi-e-bah (Aphrodisiac), Muwallid-e-mani (Spermatomatogenic), Daf-e-sumoom (Antidote), Kasir-e-riyah (Carminative), Jaali (Cleanser/Detergent), Mudirr-e-bawl (Diuretic) wo Mudirr-e-hayd (Emmenogoggue), Muhammir (Rubefacient), Hazim (Digestive), Mulaiyan (Laxative), Muzliq-e-mani (Lubricant), Muddir-e-shir (Galactopoietic), Mufattih-e-Sudad (Deobstruent), Musakhin (Analgesic), Mulattif (Demulcent), Mufattit-i-hasah (Lithotriptic) and whole plant is considered as aphrodisiac. This is a review paper which discusses morphology, pharmacological action, ethno-medicinal and therapeutic uses of this medicinal plant in perspective of Unani medicine. This review has been done through online searches of databases such as PubMed, Google Scholar, Embase, science direct and hand search for classical textbook available in different libraries. It concluded that JIRJEER (Eruca sativa) is one of the best herbal medicines in treatment of Antiulcer, Antibacterial, Fertility, Hepato-protective, Hyperlipidemic, Antioxidant, Antihypertensive, Anti-inflammatory and Anti-edema, Nephro-protective, Antidiabetic, Antifungal and Anticancer properties.

The effect of ethacrynic acid (EA) on the renal secretion of PAH was examined in cat kidney. $C_{PAH}$ and $T_{PAH}$ were measured before and after infusion of EA $(0.5{\sim}50mg/kg)$ through the femoral vein. The following results were obtained: 1) In the dosage range of 0.5 to 25 mg/kg, EA increased the urine flow, and sodium and potassium excretion in dose-dependent manner, but the glomelular filtration rate was decreased as the dosage of EA was increased. 2) $C_{PAH}$ and $T_{PAH}$ were decreased by EA in the dosage range of 3 to 25 mg/kg and 1 to 50 mg/kg, respectively, in dose·dependent manner with the dosage to cause 50% inhibition of about 5 mg/kg. 3) With dosage of 0.5mg/kg, EA appeared to exert a great effect on diuretic response without the influence on $T_{PAH}$. At 10min after infusion of EA, a potent diuretic effect appeared, while $T_{PAH}$ did not show a significant change. These results suggest that the action mechanism of EA on tubular secretion of PAH may be different from that on natriuresis. 4) With dosage of 5 mg/kg, EA did not inhibit the Na-K-ATPase activity in microsomal fractions from both cortex and medulla. 5) The double reciprocal plot ($l/T_{PAH}$ versus $l/P_{PAH}$) suggested that EA inhibited the P AH secretion by a competitive pattern. However, probenecid, a prototypic inhibitor of the organic acid pump, had no influence on both the inhibitory effect of $T_{PAH}$ and the natriuretic effect by EA. These results suggest that in vivo EA altered tubular secretion of P AH through interactions with receptors that are not identical with the Na-K-ATPase.

The matrix affects the dissolution of furosemide, which is almost insoluble in the dissolution medium. In order to understand the effect of the matrix on the dissolution of furosemide, lactose, starch, $Avicel\;^{\circledR}pH\;101$, $Avicel\;^{\circledR}pH\;301$, $SiO_2$ and talc were used as the matrix and the solvent deposition method were used. The dissolution characteristics of four dissolution medium were compared to each other using various ratio of drug-to-matrix. The results are as follows: 1) Lactose was shown to be superior and talc was to be inferior to the other matrixes investigated. 2) A maximum dissolution rate and dissolution amount of furosemide were observed in 1 : 10 ratio of the drug-to-matrix. 3) $T_{80%}$ of 1 : 10 ratio of the drug-to-matrix in pH 7.2 was 1 min. from FM-lactose and 30 min. from FM-talc. $T_{50%}$ in pH 4.2 is 2 min. from furosemide-lactose and 150 min. from furosemide-talc. Total amount of furosemide in pH 1.2 at 30 min. were enhanced 13.3 fold in furosemide-lactose and 3.5 fold in furosemide-talc compared to the control. Diuretic action of those furosemide-lactose and furosemide-talc was also evaluated by monitoring changes in urinary excretion of sodium, potassium and urine volume in rat. The accumulated urine volume were enhanced 1.7 fold in furosemide-lactose (1.5) compared to the furosemide.

Four polymorphic forms (I, II, III and IV) of hydrochlorothiazide have been characterized on the basis of x-ray diffractometry and differential thermal analysis. Form I was obtained by crystallization from N, N-dimethylformamide and Form II was crystallized from hot methanol. Form III was precipitated from sodium hydroxide aqueous solution by treatment with hydrochloric acid and Form IV was crystallized from 50% methanol. The metastable form I was a most stable form among four polymorphs, which was stable more than ten months at room temperature. The thermodynamic parameters such as heat of solution, enthalpy, entropy, free energy difference and transition temperature were determined by the measurement of intrinsic dissolution rate. The transition temperature and the heat of transition between the metastable Form I an Form II were determined to be $299.15^{\circ}$K and 5.03 Kcal/mole, respectively and free energy difference ($\delta$ F) was 302. 13 cal/mole. Diuretic action of these four polymorphic forms was also evaluated by monitoring the difference in urinary excretion of sodium, potassium and magnesium in rats.
