Although a variety of agents have been introduced for the treatment of hypertension, the ideal drug has not yet been discovered. However, among the agents available, prazosin hydrochloride (Minipress(R)) appears to be accepted by the majority of physicians as it lowers blood pressure effectively with relatively low incidence of side effects. It has been considered that the hypotensive effect of prazosin is a result of peripheral vasodilation due to direct relaxation of vascular smooth muscle and blockade of alpha-adrenergic receptors in the arteriolar smooth muscle. Following the development of prazosin. many trials have been designed to potentiate its hypotensive effect by the combination with other agent, especially thiazide or beta blocker. Minizide(R), a preparation that thiazide is added to prazosin, is an example. The antihypertensive effect of Minizide(R) was evaluated in 30 hypertensive subjecs. The results were as follows; 1. The systolic and diastolic blood pressure were effectively lowered in both supine and standing position with the overall response rate of 86.7% as judged to be responsive in one that lost systolic pressure more than 15 mmHg and distolic pressure 10 mmhg. Among 30 cases 18 cases could be maintained with their diastolic pressure below 90 mmHg and 24 cases with their diastolic pressure below 100 mmHg by the end of 8th week of treatment with the daily dose of minizide(R) from a half tablet to two tablets. 2. During the period of 8 weeks, troublesome postural hypotension was not observed in any case. The pulse rate was not accelerated significantly by Minizide(R) treatment. 3. Minimal side effects were recorded in 5 cases; two of mild nausea, one of slight dizziness, one of minimal gastrointestinal irritation symptom and one of mild glucosuria. neither of them hindered the authors from finding the study.

Malignant transformation develops in a little less than 2% of mature cystic teratomas. A wide variety of malignant tumors may arise within benign mature cystic teratomas, and the most common of these is squamous cell carcinoma, which account for 75~85%. In general, the tumors are in an advanced stage and the prognosis is poor as most patients die within a year. However, when the tumor is confined to the ovary, they have a good prognosis and the 5-year survival rate is 63~83%. We experienced three cases of squamous cell carcinoma arising in mature cystic teratoma. Two of the carcinomas occurred in postmenopausal women: 58-(case 1) and 66-(case 2) year-old, and were confined to the ovaries. They were alive 37 months and 18 months after the operation, respectively. The third case was a 45-year-old premenopausal woman who had an extraovarian extension of the tumor and early recurrence within two months. Histologically, cases 1 and 3 were conventional well to moderately differentiated squamous cell carcinomas and case 2 showed a well-differentiated squamous cell carcinoma with exuberant proliferating trichilemmal tumor-like areas.

Peri-vater divertieula may interfere with the normal flow of biliary and pancreatic secretion, thus leading to pancreatobiliary diseasa and the very presence of juxtapapillary diverticulum makes cannulation technically difficult and contributes to the low success rate. In this present series, the relationship between duodenal diverticula and age, sex, and biliary-pancreatic pathology was stud.ied in 1400 patients examined with ERCP. The results are as follows. 1) Duodenal diverticula was demonstrated in 73 of 1400 patients(5, 2%). 2) The incidence of duodenal divertieular increased with age and they were more frequent in men. 3) The cannulation of one or both duct system was suecessful in 69 of the 73 patients, the success rate was 94. 5%. 4) The biliary pathology was found in 41 of the 73 patients and the pancreatic pathology in 6 of the 73 patients. The rnost common finding was biliary calculi which were demonstrated in 35 patients(47. 9%).

PURPOSE: To describe MR imaging features of hypoxic brain damage in relation to time elapse and prog-nosis of patients. MATERIALS AND METHODS: We reviewed 19 MR studies of 18 patients with hypoxic brain damage. MR imaging studies were performed between 1 to 20 days after the hypoxic insults (mean 8.6 days). MR images were analyzed with regard to the locations of abnormal signal intensities, the presence of brain edema. And imaging findings were correlated with the time elapse after the insults and the prognosis of patients. RESULTS: On 19 cases of MR studies, abnormal high intensities on T2-weighted images were found in the basal ganglia (15, 78.9%), cerebral cortex (13, 68.4%), white matter (9, 47.4%), thalamus (6, 31.6%), cerebellum (4, 21.1%) and brainstem (1, 5.3%), respectively. Cerebral cortical involvement was typically bilateral and diffuse, but sometimes limited to the parieto-occipital area. The brainstem and cerebellar involvement was rare and in all cases, cerebral cortical lesions accompanied. Most of the white matter lesions were accompanied with cortical and deep gray matter lesions and found in subacute period(>6 days). The cortical high signal intensity lesions on T1-weighted image were found mostly in subacute stage, but in some cases involvement was also found in acute stage (< or =6 days). The cortical edema is found on 11 cases in acute and subacute stages. In cases of recovered consciousness, cortical involvement and edema on MR were rare. CONCLUSION: MR findings of hypoxic brain damage were various, but diffuse bilateral involvement of cortex and/or deep gray matter was found in most of the cases. White matter involvement was rarely found in acute stage and usually found in subacute stage. In cases of good pronosis, cortical involvement and edema were rare.

BACKGROUND: Although post operative pain has been reduced significantly since the advent of laparoscopic surgery, many patients still complain of moderate abdominal and shoulder pain after surgery. METHOD: Patients scheduled for elective laparoscopic cholecystectomy were assigned to three groups by simple randomization(12 patients per group). Group I patients(control) had no specific treatment, group II patients had 10 ml of normal saline instillation, and group III patients had 10 ml of 0.5% bupivacaine instillation. Instillation was made directly into the gallbladder bed and right subdiaphragmatic space under direct vision by the surgeon at the end of the procedure and before evacuating the pneumoperitoneum. RESULT: Compared to that of the group I, VAS of group II and III did not show any statistically significant difference. Compared to the group I, group II & III showed no significant difference in numbers of requests of Tiaprofenic acid during the 36hours after the surgery. CONCLUSION: Topical instillation of 0.5% bupivacaine 10 ml to the gallbladder bed and right subdiaphragmatic space after laparoscopic cholecystectomy is not effective for the post operative pain control.

Upper gastrointestinal bleeding in cirrhotic patients is a serious emergency which is associated with high mortality. Cirrhotic patients commonly have, in additian to esophageal varices, other upper gastrointestinal lesions which accont for occasional bleeding episodes. Since the theapy of bleeding esophageal varices differs from the treatment of nonvariceal bleeding, delay and inaccuracy in determining the source of bleeding contribute ta high mortality.
