A total of 100 hookworm infested patients were divided into two groups. One group of 49 received pyrantel embonate in a single oral dose of 10 mg as the base per kg body weight and the other group of 51 a single oral dose of 5.0 gm bephenium hydroxynaphthoate for a comparison of efficacy on hookworm infestation and other intestinal helminths. Forty-two(85.7%) cases of hookworm treated with pyrantel embonate were cured and there was a 99.9 per cent mean reduction in fecal egg count. Of the 51 patients who received bephenium hydroxynaphthoate complete cure occurred in 76.5 per cent and the mean reduction in fecal egg count was 91.8 per cent. These results plus the lower incidence of side effects recorded in the pyrnatel group suggest that pyrantel embonate is the more desirable trestment. Pyrantel embonate was highly effective against Ascaris lumbricoides, Trichostrongylus orientalis and both drugs were moderately effective against Trichuris trichiura. During the course of the study measurements of hematology, biochemistry and examinations of urine specimens were carried out. All values were normal throughout the study and no significant difference was observed between pyrantel embonate and bephenium hydroxynaphthoate treated subjects. Side effects were more common in the bephenium hydroxynaphthoate treated group.

Present trial was carried out to evaluate the anthelmintic efficacy of oxantel/pyrantel tablets against intestinal nematode infections, and to determine the efficacy of oxantel tablels against Trichuris infection. A total of 34 subjects with the mixed infections were treated with oxantel/pyrantel tablets (100 mg/tablet each) in a single dose of 15 mg/kg body weight, and another group of 22 Trichuris infected cases received oxantel pamoate tablets (125 mg/tablet) in a single dose of 15 mg/kg. All stool examinations were done before the treatment and 3 weeks after the treatment. The cellophane thick smear (Kato's technique) and Stoll's dilution egg counting method were employed. The results of the trial were summarized as follows: The cure rates (egg negative conversion rates) and egg reduction rates for oxantel/pyrantel tablets were 85.3 percent and 97 percent in trichuriasis, 100 percent each in ascariasis and ancylostomiasis. The oxantel tablet treated group demonstrated a cure rate of 90.9 percent and an egg reduction rate of 96.3 percent in the treatment of Trichuris. There were no detectable objective and subjective side effects in this trial. Both oxantel/pyrantel and oxantel pamoate tablets were readily accepted and well tolerated.

Higenamine was isolated originally from Aconiti tuber from Aconitum species and recently Higenamine was synthesized. The purpose of this study is to investigate the adrenergic effect of Higenamine on rabbit cardiovascular system. Blood pressure, cardic output, systemic vascular resistance and heart rate were measured after intravenous injection of Higenamine(2-100microg/kg/min). The effects of Higenamine were compared with those of other sympathomimetic drugs. The changes in the cardiovascular systems after pretreatment with Propranolol, Atenolol and Hexamethonium were also studied. The following results were obtained. 1) Higenamine increased the cardic output and the heart rate and decreased the blood pressure and the systemic vascular resistance. Those changes were dose-dependent. The duration of action of Higenamine was 5 to 8 minutes. 2) The effects of Higenamine were similar to those of Isoproterenol. The amount of Higenamine was more than 100 times the required amount of Isoproterenol in order to obtain the same casdiovascular effects. 3) The effects of Higenamine were blocked by Propranolol, The increase of cardic output and heart rate were blocked by Hexamethonium. Higenamine has stimulating action on beta1 and beta2 receptors. But Higenamine is much less potent than Isoproterenol.

A total of 56 subjects with multiple nematode infections with T. trichiura, Ascaris, hookworms and Enterobius were treated with oxantel and pyrantel pamoate mixture in a paratable suspension(50 mg of each per ml). A single dose of 10 mg per kg body weight in each cured 100 per cent of 54 subjects with Ascaris, 97.1 per cent of 35 subjects with hookworms, 77.8 per cent of 36 with Enterobius and 73.2 per cent of 56 subjects with T. trichiura infestation. The mean egg per gram stool reduction rate in T. trichiura infection was 91.9%. Of the 31 subjects infected with Ancylostoma doudenale 96.8% were cured with a single dose and 4 infected with Necator americanus showed a 100% cure rate with a similar daily dose on 3 consecutive days. Side effects were few and mild. There was no clinical or laboratory evidence of drug toxicity. These findings show a single dose of oxantel and pyrantel pamoate mixture to be a highly effective and acceptable treatment for multiple infections with these nematodes.

The present study was performed to investigate the role catecholamine in the genesis of reperfusion injury of ischemic heart. The possible involvement of catecholamine in the xanthine oxidase-linked production of oxygen free radicals was studied. langendorff preparations of rat hearts were made ischemic for 60 min followed by reperfusion. Upon reperfusion norepinephrine(NE) was significantly released into the coronary effluent regardless of oxygenation of the perfusion solution. Both the increased releases of creatine phosphokinase(CPK) and malondialdehyde(MDA) and the production of superoxide anion in the ischemic-reperfused hearts were significantly reduced by the treatment with either reserpine, a catecholamine depletor, or propranolol, a beta-adrenergic receptor blocker. In the reserpinized hearts, infusion of exogenous NE reversed the releases of CPK and MDA and the superoxide anion production to the original higher levels. The releases of CPK and MDA as well as the production of superoxide anion induced by NE in the reserpinized hearts were significantly depressed either by allopurinol, a specific competitive inhibior of xanthine oxidase(XOD), or by the calcium removal from the perfusion solution. Compared with the XOD activity of control ischemic hearts, that of the hearts treated with reserpine or propranolol showed lower activity in the oxygen radical producing 0-form and higher activity in D/0-form. In the reserpinized ischemic hearts, infusion of exogenous NE increased 0-form, but decreased D/0-form of XOD. The changes in XOD activities induced by exogenous NE was prevented by phenylmethylsulfonyl fluoride(a serine protease inhibitor) and pimoxide(a calmodulin inhibitor) as well as by calcium removal from the perfusion solution. It is suggested from the results that in the inchemic-reperfused heart of rat catecholamine participates in D/0 to 0-form conversion of XOD by promoting the calcium-calmodulin-dependent proteolysis and plays a contributing role in the production of oxygen free radical.

Tinidazole (Fasigyn), a new drug which is active in vitro and in vivo against Entamoeba histolytica, was used in 30 Korean patients with acute and chronic intestinal amoebiasis. In aute amoebic dysentry eight of ten patients given tinidazole 150 mg q.i.d. for 10 days were cured clinically and parasitologically. In chronic intestinal amoebiasis, the parasitological cure was obtained 6 out of 10 patients given150 mg q.i.d. for 10 days and 8 out of 10 in patients given 300 mg q.i.d. for 7 days. Tinidazole is well tolerated and is free from serious toxicity. There was no significant alteration in blood count, liver function tests and urine analysis of any of the patients treated with tinidazole.

Hypergammaglobulinemic purpura of Waldenstrom is characterized by recurrent episodes of petechiae, hypergammaglobulinemia, an elevated erythrocyte sedimentation rate, and the presence of rheumatoid factor, and leukocytoclastic vasculitis or mild lymphocytic perivasculitis. There is a primary type and a secondary type which is associated with other autoimmune diseases. We present a csae of a 48 year-old female with hypergammaglobulinemic purpura of Waldenstrom. She showed characteristic clinical, histopathological and laboratory findings consistent with hypergammaglobulinema purpura of Waldenstrom. Although there was a decrease in the Schimer test, we couldt den ostrate an association with Sjogrens syndrome. We think that this case may be a secondary type and needs a follow-up study.

In order to evaluate the the effectiveness of low-dose longterm Vibramycin (Doxycycline) treatment on Acne Vulgaris, a double-blind study was performed on fifty two patients with Acne Vulgaris. The patients were classified as to the severi.ty of their disease before treatment according to Wand. et al. The degree of the effcctiveness of the treatment was evaluated every other week for 12 weeks on the grounds of clinical improvement. The therapeutic results obtaincd were as follovs: araong the 19 patients who received 50 mg per day for 12 weeks, 13 cases (72.2%) showed excellent improverrent after 6 weeks; whereas in thc placebo group only 4 out of 15 patients (26. 7%) showed good response, Statistical analysis of the data revealed that there was a significant difference (p<0.05) in effectiveness between the Vibrarzycin 50mg per day group and the placebo group. Among the 19 patient who received a 100mg capsile orally per day for 4 weeks (subsequently this group received 50mg per day for 8 weeks) 13 cases.(68.4%) showed excellent improvement in 4 weeks; whereas in the placebo group only 4 cases(26, 7%) showed good respnnse Statistical analysis of this data revealed that there was a significant difference (p<0. 05) in efectivencess the Vibramycin 100mg per day group and the placebo group, It was noted that 44 out of 52 patients (83%) had a distinct family history of the disease, suggesting that there might be a predisposing hereditary factor involvcd in the manifestation of Acne Vulgaris It is concluded f rom this study that Vibramycin, when administrated in a dose of 50mg per day for more than 6 weeks is effective in the treatment of Acne Vulgaris.

The purpose of this study is to review epidemiological and clinical characteristics of diverticular disease of the colan in Korea and to discuss the difference of the findings from those in other countries. Reviewing all thebarium enema films taken at the Seoul National University Hospital retrospectively for the last 8 years. that is, from January 1, 1980 to December 31, 1987, we observed the annual and overall incidence of the disease, the number and location of the diverticula, and the presenting symptoms of the cases. The results are summarized as follows: 1) Out of the patients examined, 237 cases had one or more diverticula in the colon, the overall incidence being 1.32%, 2) The annual incidence increased progressively for the last 8 years, from 0.25% in 1980 to 2.53% in 1987. 3) The mean age of the patients at the time of diagnosis was 51 years. The male to female ratio was 2.5. 4) The diverticula were located on the right side in 81.0% of the cases, on the left side in 10.6%, and on both sides in 8.4%. 5) In 82 cases (34.6%) single diverticulum was found, whereas 34 cases (14.3%) had more than 10 diverticula. 6) The most frequent symptoms for taking barium enema were abdominal discomfort and pain (34. 2%) and changes in bowel habits (33.8%}, whereas 45 casea (19.0%) had the examination just for a routine health check. In conclusiion, the diverticular disease of the colon is still uncommon in Korea as compared with in western countries, and the right colon type is far more freqtaent than the left colon type. However in recent years the incidence increases quite rapidly and the left colon type is getting more common.

PURPOSE: To report the relationship between the extent of rupture of the trabecular meshwork and intraocular pressure changes in traumatic hyphema patients. METHODS: Ninety-five trabecular meshwork rupture patients were selected from a group of traumatic hyphema patients. Identification and measurement of the rupture of the trabecular meshwork were performed by gonioscopy, and intraocular pressure was measured by Goldmann applanation tonometry until 3 months after the trauma. RESULTS: There were statistically significant differences of IOP between the traumatic eyes and the contralateral eyes at day 2, 3, 5, and 1 month (p=0.000, 0.018, 0.001, 0.040, respectively). IOP was highest at the 2nd day post-trauma, and dropped by the 5th day, after which it rose slightly. The relationship between the extent of trabecular meshwork rupture and the difference of IOP was positive at the 2nd day post-trauma (r=0.259) and negative at the 6th day post-trauma (r=-0.296); these differences are statistically significant (p=0.020, p=0.041, respectively). CONCLUSIONS: A rupture of the trabecular meshwork can be measured using gonioscopy, and the change of IOP in a trabecular meshwork rupture increases as the extent of the rupture of the trabecular meshwork increases.
