In an attempt to clarify the epidemiological feature of distomiasis in Tongjin riverside area, the prevalence of distomiasis in the residents and infection rates of the metacercariae in fresh-water fishes were investigated at the upper, middle and lower reaches of the river from January to April 1984. The results obtained were summarized as follows: Out of a total of 931 fresh-water fishes which composed of 33 different species, 611 fishes (65.6 percent) of 31 species were found positive with digenetic trematode metacercariae of 16 different species, and there were some differences in infection rates of the metacercariae among the fishes in the3 parts of the river; 53.8 percent in upper, 80.7 percent in middle, and 61.0 percent in lower reaches, respectively. Infection rates of the metacercariae of Exorchis oviformis, Metagonimus yokogawai, Echinochasmus japonicus, Metorchis orientalis and Clonorchis sinensis in the fishes were 48 percent, 29 percent, 11 percent, 7.9 percent and 6.3 percent, respectively. The average number of the encysted larvae of Clonorchis found in fish body/gram showed 4.44 in Pseudorasbora parva, Gnathopogon coreanus (1.2), Microphysogobio yaluensis(0.76), Abbottina springeri(0.4), Acanthorhodeus asmussi (0.21) and Cultriculus eigenmanni (0.17), respectively. The average number of the metacercariae of Metagonimus found in fish body/gram disclosed 34.01 in Zacco platypus, Zacco temmincki (16.46), Carassius carassius (5.35), Moroco oxycephalus (1.54), Aphyocypris chinensis (1.5) and etc., respectively. Detection rates of the eggs of Clonorchis and Metagonimus among residents were 1.1 percent and 0.8 percent, respectively, out of a total 923 persons.

We retrospectively reviewed 11 eyes of 10 patients, with a mean age of 60.2 years, who had a functioning filtering bleb and underwent an extracapsular cataract extraction with implantation of a intraocular lens. Their mean precperative intraocular pressure was 15.8mmHg and six months postoperatively this pressure was 15.5mmHg. There was no change of medicaiton. Six eyes showed a reduction of intraocular pressure with a mean change of 3.3mmHg, 4 eyes showed a mean rise of intraocular pressure of 3.8mmHg and 1 eye remained unchanged. Transient loss of filtering bleb was observed in 3 eyes but within four weeks reformed. We conclude that the results of a filtering precedure remain unchanged after extracapsular cataract extraction with implantation of intraocular lens.

PURPOSE: Recently, several reports have documented persistent visual field changes associated with long-term use of Vigabatrin, an antiepileptic drug. Epilepsy is a common disease in children, therefore we investigated perimetric changes in children who were on Vigabatrin treatment. METHODS: Total 36 eyes of 18 patients who had been treated with Vigabatrin were tested with Humphrey Field Analyzer. The visual fields were assessed using central 30-2 threshold test and peripheral 60-4 threshold test. RESULTS: In central 30-2 threshold tests, 13 eyes(40.6%) showed mild visual field constrictions and 4 eyes(12.5%) showed severe visual field constrictions. In peripheral 60-4 threshold tests, 23 eyes(71.8%) showed visual field changes. CONCLUSIONS: Asymptomatic visual field loss may develop in Vigabatrin-treated children. Regular examinations of the visual field is warranted for Vigabatrin-teated children.

A gastric intramural hematoma is very rare and commonly associated with trauma, anticoagulation therapy, coagulopathy, pancreatic disease, aneurysm and peptic ulcer disease. This is a case of gastric intramural hematoma which occurred in a patient taking aspirin after hypertonic saline-epinephrine injection for bleeding from a biopsy site. We describe a case of gastric intramural hematoma that was successfully managed with conservative therapy.

OBJECTIVE: The aim of this study is to determine whether any association exists between preeclampsia and the maternal serum level of nitric oxide (NO) and platelet activating factor (PAF). METHODS: NO concentrations were measured using Stuehr's method and PAF concentrations were measured with [3H]PAF scintillation proximity assay (SPA) system (Amersham Pharmacia Biotech). Data were analyzed with SAS windows version 6.12, with significance established at p<0.05. RESULTS: The mean (+/-SD) maternal serum concentrations of NO were significantly higher in the group with severe preeclampsia (5.535+/-0.343 ug/ml) and mild preeclampsia (5.891+/-0.481 ug/ml) than in the normotensive pregnancy group (2.036+/-0.744 ug/ml) (p<0.05). The mean (+/-SD) maternal serum concentrations of PAF were significantly higher in the group with severe preeclampsia (928.9+/-32.3 ng/ml) and mild preeclampsia (789.1+/-63.9 ng/ml) than in the normotensive pregnancy group (435.8+/-59.5 ng/ml) (p<0.05). The mean birth weight was lower in the mild and severe preeclampsia groups than in the normotensive pregnancy group (p<0.05). CONCLUSION: Maternal serum NO and PAF concentrations were more increased in preeclampsia than normotensive pregnancy group. NO may therefore serve as compensatory mechanism for vasoconstriction of preeclampsia and PAF as a marker for the risk of preeclampsia.

OBJECTIVES: To analyze differences in health behaviors among the social strata in Korea by using the 1995 National Health and Health Behavior Survey Data. METHODS: Study participants numbered 2,352 men and 1,016 women aged between 15-64 years old, with housewives, students and non-waged family workers excluded. Health behaviors in this study were defined according to the recommendations of the Alameda 7 study. The measure of health behaviors was based on the Health Practices Index(HPI; 0-5 range, with the exclusion of snacking between meals and regularly eating breakfast) developed by the Alameda County research. The significance of the relationship between social strata and HPI was assessed by considering the adjusted means from the multi-variate model. RESULTS: For men, incidence rates of never having smoked, no/moderate use of alcohol, regular exercise, and regular 7-8 hours sleep per night were higher in the upper social strata. Meanwhile, for women, incidence rates of never having smoked, no/moderate use of alcohol, appropriate weight, regular exercise, and regular 7-8 hours sleep per night were higher in the upper strata. HPI varied significantly among social strata in both sexes (p<0.001), a result which held true when adjusted for age, education, income, social insurance type, marital status and region. CONCLUSIONS: Health behaviors assessed by Health Practices Index(HPI) varied significantly among social strata for both sexes. Therefore, the existing gap in health behaviors among social strata can be corrected more effectively by target oriented health promotional activities.

PURPOSE: The aim of this study was to determine the incidence and malignant rate of incidental asymmetric palatine tonsillar uptake (ATU) on (18)F-FDG PET/CT in various clinical indications and to evaluate the clinical and PET/CT findings suggesting malignancy. MATERIALS AND METHODS: We retrospectively reviewed a total of 2,901 patients (58.4+/-12.3 yrs, range 20~88 yrs, M:F=1,841:1,060) who underwent (18)F-FDG PET/CT during an 1-year period with various indications except primary tonsillar cancer and lymphoma evaluation. On (18)F-FDG PET/CT, metabolic abnormality of the palatine tonsil and cervical lymph node were visually assessed. ATU was defined as increased palatine tonsillar uptake with diffuse, focal, or irregular pattern compared to contralateral side. The incidence and malignant ratio of ATU were evaluated according to clinical and PET/CT findings. RESULTS: Of 2,901 cases, 290 (10.0%) showed ATU. The incidence of ATU showed seasonal variation and was high in the winter (12.1%). Of 209 cases with ATU confirmed pathologically and/or clinically, five (2.4%) were malignant lesions. ATU with irregular uptake pattern (2/2) and in cases referred for cervical lymph node metastasis of unknown origin (3/5) were frequently associated with malignant lesion (p<0.05). CONCLUSION: ATU was not infrequently observed on (18)F-FDG PET/CT, and the malignant risk of ATU was low. However, ATU with cervical lymph node metastasis or with irregular pattern on PET/CT would be further evaluated by the histopathologic examination.
