Ethyl alcohol is believed to inhibit the secretion of antidiuretic hormone (ADH) from the neurohypohysis, and an increase in urinary volume and reduction in the extracellular fluid volume may follow. In the case of acute alcohol intoxication, the red cells may be exposed. to the increasing level of the blood alcohol, and are in danger of being oxidized and/or hemolysed, for which the blood glutathione may exert a protective action. The aim of this study is to elucidate the acute effect of alcohol on the hematocrit, assuming that the decreased secretion of ADH will result in an increased value of the hematocrit, and also the change of oxidized glutathione (GSSG) and reduced glutatbione (GSH) of the blood following by the adminstration of alcohol. Albino rats were used throughout the experiment, and a rat was given 50% ethyl alcohol in the dose of l. 5 ml per 100 gm of body weight by the oral intubation. In all the alcohol administered cases, the rat immediately following the intubation became comatose and no voluntary effort to intake food or water was observed for at least twenty hours. The rat was sacrificed first by a strong blow on the head and the thorax was immediately opened. The blood sample for both hematocrit and glutathione was drawn from the thoracic cavity with the heart puncture if necessary after cutting the pulmonary and carotid arteries. The experiment was performed at 1,3,6,12 and 24 hours after the alcohol administration, and hematocrit was determined by the conventional hematocrit centrifuge and reader. The blood GSH was measured by the method of Ellman, and GSSG was measured by the method described by Dohan and Woodward. Controls were set which received the same amount of distilled water in place of alcohol.

This experiment is designed to find differentially expressed genes in p388D1 cells that are specific for the serum deprived state. Serum starvation induces cells to enter the quiscent state in the cell cycle and is used to arrest cell growth or synchronize the cell cycle. Differential display and ribonuclease protection assay were used to identify quantitative change in gene expression. Nineteen genes that showed a differential expression in the differential display were cloned and 7 clones were verified by a ribonuclease protection assay. Among the 7 clones clone-16 showed same expression pattern in comparison with the differential display. Deduced amino acid sequences of clone-16 had N-glycosylation motif and seems to be a secretory protein. Getting a full sequence of clone-16 is critical for the characterization of it.

Angiodysplasia of small bowel is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that the lesion is impalpable, and invisible to the naked eye, so it usually cannot be identified unless bleeds actively at the time of surgery. Arteriography gives a little information about wax and wane pattern of bleeding in the lesion. Endoscopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few millimeters in diameter. Transillumination of the intestinal wall from inside of the lumen to the outside in a dark room can define the precise vascular anatomy of the wall. The delicate lesion of the angiodysplasia can be identified by this transillumination method. We described a simple intraoperstive endoscopic translllumination technique used successfully to identify an angiodysplasia in the small bovwel prior to the bowel resecion. This report summarized our experience and review of literature.

The routine screening of patients for hypercalcemia has increased the incidence of hyperpa-rathyroidism, But, Primary hyperparathyroidism is relatively rare disease in korea. Especially, primary hyperparathyroidism caused by parathyroid chief cell hyperplasia has not been reported. The numbers of patients with bone disease, renal stones, other severe complication has declined, but the numbers of patients with psychiatric and neuromuscular disturbance or with asymptomatic disease has increased. We experienced a case with severe bone diseases due to primary hyperparathyroidism caused by parathyroid chief cell hyprepiasia which was confirmed through the mearsurement of serum calcium and parathyroid hormone, neck CT scanning and surgical exploration and which was managed by total parathyroidectomy with autotransplantation.

In case of acute obstruction secondary to colorectal carcinoma, emergent surgical intervention is needed and many types of operation including staged operation, subtotal colectomy and intraoperative colonic lavage have been tried. But those operations are not elective and have high morbidity and mortality. By the use of the Flexible covered stent, we resolved obstruction in 4 cases of colorectal carcinoma and prepared the bowel mechanically by polyethylene glycol. After improvement of the general state of the patients and assessment of the extent of the disease, we performed elective and single stage operation in all cases and had no complications associated with the stent. The treatment with the Flexible covered stent is a safe and effective procedure for malignant colorectal obstruction that makes it possible to perform a single stage operation.

Urinary excretion of 5-hydroxyindoleacetic acid was determined in 114 normal Korean adults and in 110 patients suffering from peptic ulcer. The amount of urinary 5-HIAA excreted during a period of 24 hours is fairly constant in each individual but varies widely between individuals. The mean daily output of urinary 5-HIAA in normal Korean adults is 1.93 +/-0.86 (S.D.) mg, which is similar to that found in normal Chinese adults. There is no significant difference between the urinary excretion of 5-HIAA in normal subjects and in patients with peptic ulcer. Furthermore, the amount of urinary 5-HIAA seems to be influenced by neither the sex of the subject nor by the degree of gastric acidity.
