The crude methanol extract of the roots of Achyranthes aspera Linn. was investigated for its possible antinociceptive, diuretic and neuropharmacological activities in animal models. At the dose of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive effect in acetic acid induced-writhing in mice comparable to that produced by diclofenac sodium, used as standard drug. The crude extract produced significant diuretic effect at the dose of 500 mg/kg of body weight comparable to that produced by furosemide, used as standard drug. The extract also potentiated significantly the pentobarbital induced sleeping time in mice; decreased the open field score in open field test, decreased the number of hole crossed from one chamber in the hole cross test and decreased the head dip responses. The obtained results provide a support for the use of this plant in traditional medicine and its further investigation.

Furosemide의 이뇨작용에 대한 acetazolamide의 영향을 알아보고자 토끼를 4군으로 나누어 saline(0.5ml/kg), acetazolamide (10mg/kg), furosemide (0.5mg/kg), acetazolamide (10mg/kg)+furosemide(0.5mg/kg)를 각각 정맥주사하였다. 1) Acetazolamide와 furosemide 병합투여시 furosemide를 단독투여했을 때의 뇨량, 뇨중 전해질 배설량에 비하여 유의한 감소를 보였다. 2) Acetazolamide와 furosemide 병합투여시와 furosemide를 단독투여시의 뇨중 전해질과 뇨량의 fraxtional excretion rate를 비교하면, 병합투여시에 감소되어 나타났으며 뇨중전해질보다 뇨량에서 그 정도가 심하였다. 3) Acetazolamide와 furosemide 병합투여시 뇨 pH가 furosemide 단독투여시보다 높게 나타났다. 4) 뇨중 $Cl^-$배설량에 대한 $Na^+\;+K^+$배설량의 비는 acetazolamide + furosemide 병합투여군과 furosemide 단독투여군에서 유의한 차이를 보이지 않았다. Acetazolamide와의 병합투여로 나타나는 furosemide 이뇨작용의 감소는 뇨 pH의 증가 또는 ascending Henle‘s limb에서의 $Cl^-$재흡수 억제의 감소에 기인하는 것으로 사료된다.

The Youngkaechulgamtang(Y) is composed of four herbal drugs, including Hoelen(H), Cinnamomi Ramulus(C), Atractylodis Rhizoma Alba(A) and Glycyrrhizae Radix(G). In oriental medicine literatures, Youngkaechulgamtang is described to be effective in headache, inflammation, uremia, gastritis, diarrhea, hypertension. To estimate the clinical effectiveness of Youngkaechulgamtang, several pharmacological experiments were carried out. The results are summarized as follows: On $HgCl_2-induced$ renal failure rat, Youngkaechulgamtang showed the significant increase of $Na^+,\;K^+,\;Cl^-$ contents in urine and the significant decrease of creatinine and BUN concentrations in serum. Youngkaechulgamtang was more effective than mixture of 4 ingredients in the urine volume and excretion of electrolytes. In the diuretic effect, Hoelen and Atractylodis Rhizoma Alba were more effective than other drugs.

This study was performed in order to investigate the effect of diltiazem, which is a $Ca^{2+}$ channel blocker of benzothiazepine derivatives, on renal function in the dog. Diltiazem, when infused into the vein or carotid artery, produced the antidiuresis accompanied with the decreased excretion rates of sodium and potassium in urine$(E_{Na},\;E_K)$ and the increased reabsorption rates of sodium and potassium in renal tubules$(R_{Na},\;R_K)$. Diltiazem, when infused into a renal artery, exhibited the diuresis along with the increased renal plasma flow(RPF), osmolar clearance$(C_{osm})$, $E_{Na}$ and $E_K$, and decreased $R_{Na}$ and $R_K$ in only infused kidney. Above results suggest that diltiazem possess both antidiuretic action through central action and diuretic action by direct inhibition of electrolytes reabsorption rates in renal tubules, mainly distal tubule.

Cyperus rotundus L. (Cyperaceae) has been used as an analgesic, antiinflammatoty agent, diuretic and emmenagoga in folk remedies. Cyperi Rhizomata, processed and unproces sed, were extracted with MeOH and fractionated with petroleum ether (Pet. Ether), $CHCl_3$, BuOH, water. In order to investigate the effects of their fractions on kidney function of acute renal failure rats induced by $HgCl_2$ urinary volume, BUN, Creatinine, Uric acid were determined. The diuretic effect of processed Cyperi Rhizoma was significantly increased in renal failure rats, on serum chemical parameters, the significant inhibition of BUN (blood urea nitrogen) of processed Cyperi Rhizoma was revealed.

In order to investigate experimentally the clinical effects of Taeksa-Tang that was prescribed to cure the severe dizziness, the water extract of Taeksa-Tang was experimented about the effects on the diuretic action, the serum lipid, the isolated ileum and heart, the blood vessel, the blood pressure and respiration. The results of this study were obtained as follows: The diuretic action was significantly shown in rabbits. The level of total cholesterol, triglyceride and phopholipid in serum of rabbits given high cholesterol diet were significantly decreased. The contraction of the isolated ileum of mice induced by acetylcholine chloride and barium chloride was remarkably inhibited. The vasodilating and hypotensive actions were noted in rabbits. Negative inotropic action on the isolated frog heart was recognized.

Methoxyverapamil, $Ca^{2+}$ channel blocker, when given intravenously by means of bolus, produced the transient increase of urine flow, and then methoxyverapamil was infused in this experiments. Methoxyverapamil, when infused into vein, elicited the increase of urine flow ancampanied with the increased glomeralar filtration rate(GFR), renal plasma flow(RPF), excretion amounts of sodium and potassium in urine($E_{Na},\;E_k$) and osmolar clearance(Cosm), wherease produced the no change of free water clearance($C_{H2O}$) and the reduction of reabsorption rates of sodium and potassium in reral tubules($R_{Na},\;R_k$). Methoxyverapamil, when infused into a renal artery, exhibited the diuretic action in only infused Kidney, at this time changes of renal function were the same aspect to that of intravenously infused methoxyverapamil. Methoxyverapamil, when infused into a carotid artery, exhibited the decreased urine flow along with the reduction of Cosm, $C_{H2O}\;and\;E_{Na}$. Above results suggest that methoxyverapamil possess both the diuretic action by direct action in kidney and antidiuretic action through the central function.

The effect of BRL 34915, a $K^{+}$ channe$Na^{+}$l opener, on renal function was investigated in anesthetized dog. BRL 34915, when given into the vein, elicited the decrease of urine volume accompanied with the reduction of renal plasma flow (RPF), osmolar clearance ($C_{osm}$) and amounts of sodium excreted into urine ($E_{na}$), whereas reabsorption rate of sodium in renal tubules ($R_{na}$), ratio of $K^{+}$ against $Na^{+}$ in urine ($K^{+}$ /$Na^{+}$) were elevated significantly with a partial fall of mean arterial pressure (MAP). BRL 34915 injected into a renal artery produced the diuretic action along with the increase in RPF $C_{osm}$, $E_{na}$ and amounts of potassium excreted in urine ($E_{k}$), and the decrease in $R_{na}$, reabsorption rate of potassium in renal tubules ($R_{k}$), free water clearance ($C_{H20}$) and $K^{+}/Na^{+}$ ratio in only ipsilateral kidney, however changes of the renal function were not observed in control kidney. BRL 34915 given into carotid artery exhibited the same aspect as changes of renal function induced by intravenous BRL 34915. These results suggest that BRL 34915 has dual effects, renally acting diuretic and centrally acting antidiuretic action.n.

Attempts were to investigate the effects of 'Bojungikgi-tang' on the digestive system, blood pressure and diuresis. The results showed that relaxing action was shown on the isolated ileum in mice and that strong antagonistic actions were seen on $BaCl_2$, acetylcholine and histamine-induced contraction of the ileum in mice and guinea-pigs that the relaxing effect of the intestinal smooth muscle was recognized. Inhibitory effects on transport rate in the small intestine of mice and castor oil-induced catharsis in mice were noted. Inhibitory action on the secretion of gastric juice, pH ascending effect and decreasing effect of the free acidity and total acidity were recognized. Continuous hypotensive action was seen, but when the vagus nerve was cut, hypotensive action was remarkably decreased. The diuretic effect was also recognized.

This study is an attempt to study the influence of clonidine, which has a central sympatholytic action, on the renal function in dogs and to elucidate its mechanism of action. Clonidine ($15\mu$g/kg) injected into a cephalic vein of the dog produced a marked increase in urine flow and in amounts of $Na^{+}$ and $K^{+}$ excreted in urine, and clearances of free water and osmolar substance, the reabsorption rates of $Na^{+}$ and $K^{+}$ in renal tubules were significantly decreased. Clonidine ($50.0]mu$g/kg) administered intravenouly elicited a transient reduction in urine flow, along with inhibition of all renal functions. Intravenous clonidine-induced diuretic effect was completely blocked by pretreatment with reserpine, and was lessened by water diuresis. Clonidine ($3.0\mu$g/kg) injected tnto a carotid artery revealed a transient diuresis with a increase in clearance of free water. Clonidine injected into a renal artery showed a significant antidiuretic effect and all functions of an experimental kidney were reduced. Antidiuretic action induced by clonidine given into a renal artery markedly suppressed by pretreatment with reserpine. The above results suggest that clonidine has dual mechanisms: 1) diuretic effect due to the central sympatholytic action and inhibition of release of antidiuretic hormone, and 2) antidiutetic effect indued by indirect symptheic stimulation in the periphery.
