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.

Mitomycin C (MMC) is an antimetabolite, antibiotic which prevents the proliferation of fibroblast and fibrosis by inhibition of DNA-dependent RNA synthesis. It has been used to increase the success rate of filtering surgery. We performed trabeculectomy and peripheral iridectomy with 0.4 mg/ml MMC application for 3 minutes in poor prognostic glaucoma patient, 26 eyes of 24 patients from February 1992 to December 1994. The postoperative change of intraocular pressure (IOP) and complications were followed up from 3 to 30 months (mean 12.4 months). The preoperative and postoperative mean IOP after 24 months were 32.3 +/- 11.4 mmHg and 12.7 +/- 3.1 mmHg, respectively. The decrease rate of IOP was 60.7% and the success rate was 71.7%. The postoperative complications were 15 eyes including 5 eyes of shallow anterior chamber, 5 eyes of hyphema, 2 eyes of conjunctival wound leakage, one eye of bleb rupture, one eye of choroidal detachment, and one eye of cataract formation.

PURPOSE: To evaluate the usefulness of spiral CT in predicting the depth of tumor invasion in patients with gastric cancer by comparing with histopathological finding. MATERIALS AND METHODS: We studied spiral CT scans of forty-eight patients, in whom gastric cancer was proven by gastrofibroscopic biopsy and surgery. After distending the stomach with 400ml tap water or effervescent granules, 100ml of contrast media was given intravenously at a rate of 3ml/sec. CT scanning was started at 45 sec after administration of the contrast material. Gastric tumors were subdivided into five types according to enhancing pattern from the inner layer of gastric wall to the outer layer. These pattern were correlated with histopathologic results. RESULT: The tumor masses were detected on CT scan in 10(77%) of 13 patients with early gastric cancer, while, the tumor masses were seen on CT scan in all patients with advanced gastric cancer. Of 9 patients with type 1 or type 2 enhancing pattern, early gastric cancer(T1) were proven in 7 patients(78%), serosal invasion (T3) in 2 patients(22%). In contrast, among 29 patients with type 4 and type 5, 22 patients(76%) were proven as serosal invasion(T3). Of 7 patients with type 3, 3 patients(43%) were proven as serosal invasion(T3), three(43%) as subserosal invasion(T2), one as early gastric cancer(T1). CONCLUSION: Analysis of morphological enhancing pattern on spiral CT is useful in predicting the depth of tumor invasion in patients with gastric cancer.

OBJECTIVE: The objectives of this study were to obtain information on MIS levels in normal and RDS neonates and to investigate the relationship between the RDS prevalence and MIS level in preterm and term neonates. METHODS: Total 131 male neonates were selected randomly and they were consisted of 50 term normal neonates, 15 term neonates with RDS, 50 prematurely born normal neonates, and 16 prematurely born neonates with RDS. Total 131 female neonates were also selected like male neonates. The venous blood was collected from all subjects and measured the level of MIS using ELISA. The ANCOVA was conducted to evaluate any influence of adjusted value of gestational age and body weight on MIS level between normal neonates and neonates with RDS. RESULTS: 1) The MIS levels of female neonates were significantly lower than those of male neonates with no overlap. 2) The MIS levels of normal female neonates were not significantly different from those of female neonates with RDS. 3) There were significant negative relationships between MIS concentration and gestational age (r=-0.777, p<0.001), and birth weight(r=-0.728, p<0.001) in normal rnale neonates. 4) There were significant negative relationships between MIS concentration and gestational age (r=-0.726, p<0.001), and birth weight(r=-0.725, p<0.001) in male neonates with RDS. 5) After adjusting the value of gestational age, the MIS level of male neonates with RDS was significantly higher than that of normal male neonates(p<0.001). 6) After adjusting the value of body weight, the MIS level of male neonates with RDS was significantly higher than that of normal male neonates(p<0.001). CONCLUSION: Male neonates with RDS had higher MIS levels than normal male neonates of the same body weight or same calculated gestational age. The results of this study suggest that MIS may play a causative or important ancillary role in the sexual dimorphism that characterizes the neonatal RDS and may be used as a predictive marker of RDS in male neonates.

PURPOSE: The Mesima-Ex is a kind of biologic response modifier, which is extracted from a mushroom called Phellinus linteus. Mesima-Ex consists of various chemical compounds which include protein bound polysaccharide, mucoprotein, triterpenoid, and quinones. Mesima-Ex exerts its antitumor effects by augmenting host immune response without any toxic side effects. In vitro study, Mesima-Ex seems to potentiates antibody dependent cell mediated cytotoxicity (ADCC) and cell mediated cytotoxicity (CMI) against tumor cells. We initiated this study to verify antitumor effects of Mesima-Ex as an antineoplastic agent. MATERIALS AND METHOD: Gastric cancer patients who underwent curative resection with normal hepatic and renal function were eligible. They were divided into two groups by random number table. One group (N=30: Mesima-Ex group) received postoperative adjuvant chemotherapy with 5-FU (500 mg/m2 weekly), adriamycin (40 mg/m2 every 3 weeks) and Mesima-Ex (6 cap daily per Os). Another group (N=37: control group) received 5-FU and adriamycin only without Mesima-Ex. NK (natural killer cell) activity, ADCC (antibody dependent cell mediated cytotoxicity), CD4 , and CD8 cells were measured and an analysis of disease free survival rate of the two study groups was performed. RESULTS: Sixty seven patients were enrolled in this study. Their median age was 55 years old. NK activity (basal activity: 25%) was enhanced significantly at the 2nd, and 4th months in the Mesima-Ex group (28.9%, 43.4%, p<0.05). ADCC was also enhanced from 37% to 42.1% at the 2nd month in the Mesima-Ex group (p<0.05). The control group did not show any significant change in NK activity or ADCC. The CD4 cell ratio was increased from 37% to 42.1% at the 2nd months in the Mesima-Ex group but not in the control group (p<0.05). There was no significant change in CD8 subsets (p>0.05). There were no toxic side effects more than grade III from Mesima-Ex administration. The two year disease free survival rate was higher in the Mesima-Ex group than that of the control group (77% vs 58%, p<0.05). CONCLUSION: Mesima-Ex can be used safely as an immunomodulator with standard chemotherapeutic agents for purpose of adjuvant chemotherapy. Mesima-Ex was effective in augmenting host immune response in vitro. The Mesima-Ex group showed a higher two year disease free survival rate than that of the control group.
