A case-control study was conducted to investigate the effect of low-level blood lead on the blood pressure. The plasma renin activity (PRA) was measured also to investigate one of the possible mechanisms by which lead may play a role to influence on the blood pressure. Seventy-two hypertensive and sixty-nine control study subjects were selected from the workers who had no history of job-related lead exposure, in Ulsan city and it's vicinity, Korea. In addition to measuring blood lead levels and PRA, body mass index(BMI), hematocrit, serum sodium, potassium, creatinine, ionized calcium, and cholesterol were measured. Also, the habits of smoking, alcohol drinking and family history of hypertension were checked. The blood lead level of the hypertensive group was 19.8+/-5.5 microgram/dl, which was significantly higher than that of the control group, 12.5+/-4.7 microgram/dl (p<0.01). On multiple logistic regression analysis, the odds ratio of blood lead level on the occurrence of high blood pressure was 1.38, also statistically significant (p<0.01). There was no significant differences between the hypertensive and the control group in the PRA or In(PRA), but there was a marginally significant linear relationship between blood lead and PRA in the hypertensive group (p<0.1). In conclusion, blood lead level which has been known to be within normal limits may be one of the possible risk factors of hypertension and PRA alteration by lead may act as one of the mechanisms.

A 6(1/2)-year-old girl developed recurrent cholangitis following hepatic portoenterostomy for biliary atresia. Computed tomogram showed an ovoid cyst (4.5 x 4.0 cm in size) in the left hepatic lobe and another tubular dilatation (2.0 x 0.8 cm in size) in the right hepatic lobe. Percutaneous transhepatic cholangio-drainage (PTCD) with cystogram showed an ovoid cyst in the left hepatic lobe (Tsuchida type A), measuring 6.6 x 5.0 cmin size. She became afebrile and anicteric with aid of PTCD and parenteral antibiotics. However she continued to drain 45-150 cc of bile per day via the tube for over 2 weeks. Then she successfully underwent intrahepatic cystojejunostomy with guidance of intraoperative ultrasonography. This case illustrates relapsing cholangitis caused by Tsuchida type A intrahepatic cyst, which was successfully managed with PTCD followed by internal drainage procedure.

This paper includes our 9-year experience of 34 infants with biliary atresia with introduction of a new non-invasive diagnostic method, that is, ultrasonographic "triangular cord" (TC) sign. TC sign was defined as visualization of a triangular or a band-like echogenicity just cranial to the portal vein. Ultrasonographic TC sign seemed to be a simple, non-invasive, time-saving and useful tool in the diagnosis of biliary atresia, representing 84% sensitivity. Active bile excretion was restored in 90% of the patients who were treated between 31-60days, 78% of those between 61-90 days, and 33% of those being 91days or older. The incidence of postoperative cholangitis was 36%, and construction of antireflux valve in the Roux-en -Y loop did not affect the incidence of postoperative cholangitis (P=0.18). As for the surgical outcome, of 34 infants with biliary atresia, 23 (68%) are alive for 2-102 months period, and 12 of them are alive for more than 5 years . Five-year estimate survival by Kaplan-Meier method was 66 %.

Recurrent epistaxis is not one of rare symptoms in children, the well-known causes of which are anatomical abnormalities of nasal cavity and systemic bleeding tendency. but, in the majority of cases of recurrent epistaxis, it is usually very difficult to find out their underlying causes, so that the treatment is only symptomatic control of nasal bleeding whenever epistaxis occurs, but it usually is impossible to manage against their underlying causes as a specific therapy. The authors considered the breakdown or weakness of vascular integrity of nasal capillary vessel wall as an important factor of recurrent epistaxis, and vitamin C, which has an important role for the synthesis of collagen fiber, could influence to the vascular integrity of nasal capillary vessels. To elucidate the relation between recurrent epistaxis and the status of vitamin C in the tissue of the patients, the authors performed urinary vitamin C loading test measuring urinary excretion of vitamin C with high-performance liquid chromatography by Sirota et al in 19 cases of control group and 32 cases of patients with recurrent epistaxis, whose underlying diseases were not identified. And also the authors administered 1.0 gm/day of vitamin C orally for the treatment of recurrent epistaxis and follow-up was done over 1 year from the beginning of treatment to evaluate the treatment response. The results were as follows: 1) The hemoglobin level was significantly decreased in patient group compared with that of control group (12.4+/-0.8 vs 9.0+/-3.2 gm/dl). 2) The results of urine loading test of vitamin C, expressed as the percent excreted ratio, revealed significantly decreased in the patient group compared to that of the control group (9.1+/-6.1% vs 13.6+/-7.9%). 3) After treatment with 1.0 gm/day of vitamin C orally, follow-up was possible in 23 cases of total 32 patients. Of the 23 patients, "excellent" therapeutic response were in 16 cases (69.6%), "good" response in 5 cases (21.7%), and "no response" only in 2 cases (8.7%). The overall treatment response were in 21 cases (91.3%). In conclusion, it seems that majority of the patients with idiopathic recurrent epistaxis in the deficient state tissue vitamin C so that administration of vitamin C will be one of the effective therapy.

This study was carried out to investigate for resistance of V. parahaemolyticus that isolated from patients of food poisoning and fish and shellfish, captured in east coast of Kyungpook province of Korea from 1985 to 1986. VP ATCC 17802 and NAG V. ATCC 6538 were used as control. In fish, shellfish and seaweed, the more temperature increased, the shorter survival time was. In case of sea-water, the more temperature rose up, the longer survival time was, particularly in 37 degrees C and 25 degrees C, the strains had survived after 6 months. And in tapwater, it was sterilized in 150 mins. and survived for 11.5 days on maximum in ground water. In kimchi, at room temperature, germicidal time was shorter more than 6 times compared with that which had been kept in refrigerator. It survived for 57.1 days in milk, 49.2 mins. in yougurt. Strains had been surviving in frozen condition at -70 degrees C even after 6 months, present study time. In resistance test in water bath at several degrees of temperature, all the strains were sterilized in 20 mins. with 60 degrees C. In resistance test to driness, number of surviving strains dropped rapidly in 10-11% water contents. In UV 2538A, strains were sterilized in 20 mins. In resistance test to alcohol, strains had survived for 0.1-4 mins. in fermentative wine of below than 25% and distilled wine of over than 25% in alcohol concentration. The bactericidal concentration of disinfectant was 1% in phenol and 3% in cresol. In 0.1M acetic acid and 0.1M lactic acid, number of surviving colonies decreased rapidly but not in citric acid. The more NaCl concentration rose up, the lower decreasing rate of number of surviving colonies was. The strains had showed sensitive response to vancomycin, chloramphenicol, gentamicin, and resisted to carbenicillin, ampicillin and kanamycin. When one day culture strain was cultured till 25th day, resistant strains to tetracycline and cephalothin were changed to sensitive.
