Steroidogenesis in Isolated Adrenal Cells of Rat

A reliable and reproducible system for the isolation of rat adrenal cells was developed, using 0.25% trypsin for cell dispersion. The suspending cell in Krebs-Ringer bicarbonate buffer containing 0.2% glucose and 0.5% bovine serum albumin was incubated for 120 minutes at 37℃ under 95% 02 and 5% C02. Corticosterone production induced by synthetic 1-24ACTH showed a dose-related increase in decapsular cells. The precision of the inter-experiment of corticosterone production was 5.0% (average coefficients of variation)

Endoscopic therapy using an endoscopic variceal ligation for minute cancer of the esophagogastric junction complicated with esophageal varices: a case report

<p>Abstract</p> <p>Introduction</p> <p>Standard endoscopic mucosal resection or endoscopic submucosal dissection is a procedure for patients with minute cancers, complicated with esophageal varices that puts them at high risk of bleeding.</p> <p>Case presentation</p> <p>We present the case of a 77-year-old Japanese man with alcoholic cirrhosis who underwent a routine endoscopy examination as a screening procedure for esophageal varices and was incidentally diagnosed as having minute cancer of the esophagogastric junction with esophageal varices. Endoscopic ultrasonography findings suggested that the minute cancer was a non-invasive carcinoma (carcinoma <it>in situ</it>) and a 2 mm in diameter blood vessel, feeding the esophageal varices, pierced the lesion. Following the examination, we carried out endoscopic treatment of the minute cancer and esophageal varices. Endoscopic variceal ligation was performed using a pneumo-activated device (Sumitomo Bakelite, Tokyo, Japan). Two years after the treatment, during the follow-up endoscopic examination on the patient, recurrence of carcinoma was not detected endoscopically or histologically.</p> <p>Conclusion</p> <p>Endoscopic therapy using an endoscopic variceal ligation device for minute cancer of the esophagogastric junction, complicated with esophageal varices, may be an acceptable and easily applicable method.</p

Penetration of the sigmoid colon to the posterior uterine wall secondary to diverticulitis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Penetration of the colon to the posterior uterine wall secondary to diverticulitis is unusual, with diagnostic methods not yet established. Non-invasive imaging, such as computed tomography and magnetic resonance imaging may help to establish a proper diagnosis, but confirmation may be reached only after surgical exploration.</p> <p>Case presentation</p> <p>We report the case of a 78-year-old Japanese woman who presented with a low grade fever and mild diarrhea which occurred two or three times a week. Computed tomography and magnetic resonance imaging demonstrated a capsular lesion including an air structure with a diameter of 5 cm, between the posterior aspect of the uterine body and the sigmoid colon. A gastrograffin enema and colonoscopy demonstrated a giant diverticulum of the sigmoid colon with no evidence of malignancy. These data confirmed the diagnosis of diverticulitis complicated by a giant diverticulum. Because of a relapsing fever after therapy with antibiotics, the patient had en bloc surgical treatment of the uterus, fallopian tubes, ovaries and sigmoid colon, the organs involved in the diverticulitis, followed by an uneventful recovery.</p> <p>Conclusion</p> <p>This is a rare case report of penetration of the sigmoid colon to the posterior uterine wall secondary to diverticulitis.</p

Increasing asthma prevalence is a major problem in Western countries. Various factors, such as allergic sensitization to indoor allergens, change in incidence in infectious diseases, and increase of air pollutants, are considered to be possible factors for increasing prevalence. Inhaled corticosteroids play an important role in asthma treatment, and its impact on asthma morbidity and mortality has already been established. In addition, recent attention has been focused on molecular targeted therapy in the treatment of bronchial asthma. Promising results of anti-IgE antibody are reported in several clinical trials and anti-CD23 antibody is now introduced in clinical trials
