  • The intent of the present work was to develop a simple, sensitive, accurate, precise, rapid and economical UV- spectrophotometric and reverse phase high pressure liquid chromatographic method for the simultaneous estimation of Spironolactone and Furosemide in bulk and combined tablet dosage forms. UV-Spectrophotometry was carried out by simultaneous equation method using 0.02 M potassium dihydrogen phosphate buffer pH 3.5: Acetonitrile (50:50) v/v as a solvent. The linearity range was 2-14 ㎍ mL-1 for Spironolactone and Furosemide with a correlation coefficient > 0.99. The chromatographic separation was achieved on 250 mm × 4.6 mm, hypersil BDS C18 column with particle size 5 ㎛, by using an isocratic mixture of 0.02 M potassium dihydrogen phosphate buffer pH 3.5: Acetonitrile: tert butyl methyl ether (49:50:1) v/v/v as a solvent at a flow rate of 1 mL min-1 and UV detection was carried out at 254 nm. The retention time were observed to be 3.666 and 6.661 minutes for Furosemide and Spironolactone respectively. The two developed methods were validated according to the ICH guidelines for accuracy, precision, linearity, LOD, LOQ and were found to be within the limits. It can be concluded that these two methods could be successfully used for the simultaneous estimation of Spironolactone and Furosemide in bulk and combined tablet dosage forms.

  • SZ95 cell is an immortalized human sebaceous gland cell line that shows the morphologic, phenotypic and functional characteristics of normal human sebocytes. Sebocytes may play crucial parts in the pathophysiologic processes and disorders of the pilosebaceous unit. The secretory activity of the sebaceous gland is remarkably species-specific and acne is an exclusively human disease. Thus, this SZ95 cells offer possibilities for investigations on the physiology of the sebaceous gland and its role in sebum-associated skin disease such as acne. In this study, we investigated the effects of 13-cis-retinoic acid (13-cis-RA) and spironolactone, frequently used as therapeutic agents of acne, on the lipid synthesis and proliferation of human sebocytes. Cell proliferation was determined by MTT assay and cytoplasmic lipid droplets was shown by Oil-red a staining. Total lipid levels were biochemically estimated by the sulfo-phospho-vanilline reagent. 13-cis-RA and spironolactone significantly inhibited proliferation and lipid levels in a dose-dependent manner. Combined treatment with testosterone and 13-cis-RA or spironolactone resulted in a lower total lipid levels than that with androgen alone. These observations indicate that 13-cis-RA and spironolactone are potent inhibitors of both cell proliferation and lipid synthesis in human sebocytes. We will provide experimental evidence that this human sebocyte cell line serves as an adequate tool for evaluating the anti-lipogenic activity of various compounds potentially useful for the bioactive cosmeceutical ingredients on acne skin, and studying the intracellular biochemical markers depending on the types of compounds from various sources.

  • Background Aldosterone has an important role in the pathophysiology of heart failure. Aldosterone promotes the retention of sodium, the loss of magnesium and potassium, sympathetic activation, parasympathetic inhibition, myocardial and vascular fibrosis, baroreceptor dysfunction, and vascular damage and impairs arterial compliance. Objectives We investigated the effects of additional spironolactone to angiotensin-converting enzyme inhibitor (ACEI) / angiotensin-II receptor blocker (ARB) in patients with heart failure.

  • Naproxen을 개의 정맥내 투여하였을때 뇨량의 감소와 더불어 삼투질제거율(Cosm), 뇨중 $Na^{+}$$K^{+}$의 배설율( $E_{Na}$ , $E_{k}$ )의 감소와 신세뇨관에서의 $Na^{+}$$K^{+}$의 재흡수율( $R_{Na}$ , $R_{k}$ )과 K/Na비의 증대를 나타내었으며 신혈류량(RPF)이 감소하였다. 한쪽 신동맥내에 naproxen을 투여하였을때 투여신(실험신)에서의 이뇨작용과 대조신에서의 항이뇨작용을 나타내었다. 경동맥에 naproxen을 투여하였을때도 뚜렷한 항이뇨작용을 나타내었다. 이와같은 두경우에서의 항이뇨 작용시의 신기능변화는 정맥내 naproxen의 경우와 같은 양상을 나타내었다. 경동맥내의 naproxen의 항이뇨작용은 신신경 제거에 의하여 영향을 받지 않았으나 정맥내로의 arachidonic acid나 indomethacin의 전처리에 의하여서는 나타나지 않았다. 경동맥내의 naproxen은 정맥내의 spironolactone의 이뇨작용을, 정맥내의 spironolactone은 경동맥내의 naproxen의 항이뇨작용을 억제하였다. 이상의 결과로 보아 naproxen은 중추성 항이뇨작용과 $Na^{+}$저류를 나타내며 이는 prostaglasdin의 합성억제와 aldosterone양 작용에 의하는 것으로 사료된다.

  • 1. Objectives This is a case of refractory ascites due to hepatocellular carcinoma treated with Sasang Constitutional Medication. Refractory ascites, which did not respond to diuretics, was improved with Jeoryeongchajeonja-tang. 2. Methods We recorded the patient's abdominal circumference, body weight and urine output daily. We also investigated the TTKG(transtubular potassium gradient) values 3 times during the treatment course. 3. Results the TTKG value of the patient was siginificantly decreased. TTKG values before administration of Jeotyeongchajeonja-tang were 8.41, 10.82, respectively and 4.25 after administration of Jeotyeongchajeonja-tang. 4. Conclusions We guess that Jeoryeongchajeonja-tang functions as an aldosterone antagonist or increases spironolactone activity through interaction between Jeotyeongchajeonja-tang and spironolactone. But the mechanism of Jeotyeongchajeonja-tang is not clear, so we need more clinical study of refractory ascites improved with Jeotyeongchajeonja-tang and biological study of interaction between Jeotyeongchajeonja-tang and spironolactone.

  • This study was undertaken to determine if the adrenocortical hormone was concerned on erythropoietic function, especially on the production of erythropoietin in the kidney. Erythropoietin titers in plasma measured in each group of mice: 1) hypertransfused mice treated with the plasma of rats pretreated with hydrocortisone, dexamethasone, fludrocortisone and DOCA 2) hypertransfused mice treated with the plasma of the rat pretreated with aldosterone antagonist and adrenocortical hormone concomitantly. Erythropoietin level in plasma were measured by the modification of DeGowin's method. The results of the experiment were summerised as follows: 1) No significant changes of erythropoietin titers were observed in hypertransfused mice treated with the plasma of rats pretreated with hyrocortisone and dexamethasone respectively. 2) Erythropoietin titers increased significantly in hypertransfused mice treated with the plasma of rats pretreated with fludrocortisone and DOCA respectively, compared with control. 3) No significant changes of erythropoietin titers were observed in hypertransfused mice treated with the plasma of rats pretreated with spironolactone and triamterene respectively, compared with control. 4) Erythropoietin titers slightly increased in hypertransfused mice treated with the plasma of rats pretreated with spironolactone or triamterene, and fludrocortisone concomitantly and also with spirolactone or triamterene and DOCA.

  • In vivo studies have demonstrated that aldosterone is an independent contributor to glomerulosclerosis. In the present study, we have investigated whether aldosterone itself mediated glomerulosclerosis, as angiotensin II (Ang II) did, by inducing cultured renal mesangial cells to produce plasminogen activator inhibitor-1 (PAI-1), and whether these effects were mediated by aldosterone-induced increase in transforming growth factor $\beta_1$ (TGF-$\beta_1$) expression and cellular reactive oxygen species (ROS) activity. Quiescent rat mesangial cells were treated by aldosterone alone or by combination of aldosterone and spironolactone, Ang II, neutralizing antibody to TGF-$\beta_1$ or antioxidant Nacetylcysteme (NAC). This study indicate that aldosterone can increase PAI-1 mRNA and protein expression by cultured mesangial cells alone, which is independent of aldosterone-induced increases in TGF-$\beta_1$ expression and cellular ROS. The effects on PAI-1, TGF-$\beta_1$ and ROS generation were markedly attenuated by spironolactone, a mineralocorticoid receptor antagonist, which demonstrate that mineralocorticoid receptor (MR) may play a role in mediating these effects of aldosterone.

  • 월경전 불쾌기분 장애(premenstrual dysphoric disorder, PMDD)는 여성의 약 $4{\sim}5%$에서 발병하며 섹스 스테로이드 호르몬 양의 변화에 대한 증가된 반응성 및 세로토닌, 멜라토닌, GABA의 감소가 원인으로 생각된다. 우울증, 계절성 정동 장애, 공황장애, 신경성 폭식증은 질병 특성 상 공통점이 있어서 월경전 불쾌기분 장애와 상호 연관성을 암시한다. DSM-IV-TR의 진단 기준에 따라 월경전 불쾌기분 장애를 진단하려면 반드시 정신적 증상이었어야 한다. 흔한 정신적 증상은 이자극성, 분노, 우울, 기분 스윙, 정동 불안정, 긴장, 불안, 피로, 음식 갈망이다. 현재로서 최선의 치료 약물은 세로토닌 재흡수 차단제이며, leuprolide, danazol, estradiol, spironolactone, bromocriptine도 사용될 수 있다. 경증 및 중증도 환자에 대한 보조적 치료로는 식이요법, 운동, 광선요법, 정신치료, 일기 쓰기 등이 있다.

  • This study was attempted to investigate the mechanism of retention of sodium and water by naproxen which is a drug among nonsteroidal anti-inflammatory drugs in dogs. Napoxen, when given intravenously in doses ranging from 30 mg to 100 mg/kg, elicited antidiuresis accompanied vath the decrease of osmolar clearance(Cosm) and amounts of sodium excreted in urine(E$_{Na}$), with the increase of sodium reabsorption rate in renal tubule(R$_{Na}$) and ratio of potassium against sodium (K/Na). Naproxen infused into a renal artery in doses ranging from 1.0mg to 3.0mg/kg/min produced both diuretic action in infused kidney and antidiuretic action in control kidney. Naproxen injected into carotid artery in doses ranging from 10.0 mg to 30.0 mg/kg exhibited antidiuretic action. Changes of renal function in the circumstances of above two antidiuresis were the same with aspect of intravenous naproxen. Antidiuretic action of naproxen injected into carotid artery was not affected by renal denervation, was blocked by pretreatment with i.v. arachidonic acid, prostaglandin precursor, or i.v. indomethacin, cyclooxygenase inhibitor. Naproxen injected into carotid artery abolished the diuretic action of i.v. spironolactone, aldosterone antagonist, and i.v. spironolactone blocked the antidiuretic action of naproxen given into carotid artery. The results suggest that naproxen produced antidiuresis, and sodium and water retention through the central system, the mechanism being related to the prostaglandin biosynthetic inhibition and aldostercfne like action.

  • Spironolactone reduces potassium excretion in renal collecting ducts and causes hyperkalemia. A 66-year-old female with urinary incontinence had to discontinue diuretics for hyperkalemia. After treatment with Jesaengsinkihwan-gagambang. she reduced urinary incontinence and her total urine volume was increased. BUN decreased from 32.2 to 16 and creatinine decreased from 1.5 th 0.9. So. we report one case of urinary incontinence with discontinuance of diuretics for hyperkalemia treated with Jesaengsinkihwan-gagambang.
