It has been studied that a variety of fauna and flora are sensitive biological indicators which reflect the severity of regional pollution of heavy metals, but in the center of part of Taegu city the controversial issue of lead poisoning attributable to the atmosphere which contains an increased concentrations of lead has been raised recently, it is usually hard to find suitable plants or animal in the areas with heavy traffic. Pigeons are ubiquitous in and around Taegu city area, inhabiting even the most densely populated areas with heavy traffic with its small body size, high metabolic turnover, and rather limited mobility, a pigeon, as a biological indicator is expected. This study was conducted to monitor lead pollution in the Taegu and kyongju city in Korea. We measured the lead content of the various tissue of three groups of feral pigeon(Columbia livia) and soil and atmospheric lead concentration. First group was obtained io heavy traffic area in Taegu City, the second group was obtained a park in Taegu city and the third group was obtained light traffic area in kyongju city. The air and soil lead concentration of heavy traffic area in Taegu city was 0.11 microgram/m2, 4.96 microgram/g, that of park in Taegu city was 0.05 microgram/m3, 2.65 microgram/g and that of light traffic area in kyonngju city was 0.03 microgram/m3, 0.01 microgram/g. The lead content of lung, blood, kidney, femur and liver of feral pigeons in heavy traffic area in Taegu city was significantly higher than pigeons obtained in a park in Taegu city and low traffic density area in Kyonfju city(p<0.01). But stomach lead content of three group did not reflect a significant difference. In this study positive correlation was found between atmospheric lead concentrations and the concentration of lead in the pigeon's lung(r=0.5040, p<0.001), blood(r=0.3322, p<0.01), kidney(r=0.4824, p<0.001), femur(r=0.7214, p<0.001) and liverer (r=0.4836, p<0.01). we can also found positive correlation between soil lead concentrations and the concentration of lead in the pigeon's femur(r=0.4850, p<0.001), kidney(r=0.4850, p<0.001) and liver(r=0.4386, p<0.01). In the pigeon`s tissue there were significant correlations between concentration of lead in the blood and kidney(r=0.4818, p<0.001), femur(r= 0.6157, p<0.001) and liver(r=0.3889, p<0.001). In conclusion, at the heavy traffic area in Taegu city, lead concentrations found in the atmosphere and soil are reflected in the lead concentrations of different tissue of urban pigeons. It is suggested that the tissue of pigeons can be good biological indicators of environmental lead pollution.

Morphometry of nuclei of the benign and malignant prostatic lesions was performed to study the relationship between nuclear size and shape and the prognosis of prostatic adenocarcinoma. Fifty one cases of prostatic adenocarcinoma and 13 cases of benign prostatic hyperplasia were included to evaluate area, perimeter, Dmax, Dmin, and 5 form factors of the nuclei by image analyzer (Zeiss Ibas 2000) using hematoxylin-eosin stained slides. All analytic factors of nuclear size and shape were significantly different between benign lesions and adenocarcinomas. Increased nuclear size was associated with nu- clear irregularity, presence of metastasis, advanced clinical stage, and high Gleason's grade and score of prostatic adenocarcinoma. On Kaplan-Meier method, survival was decreased with older age, no hormonal treatment, stage D, high Gleason's grade and stage as well as with larger size and irregular shape of the nuclei. In conclusion, morphometry of nuclei of the prostate can be a helpful tool to differentiate between benign and malignant lesions. Nuclear morphology is thought to be associated with prognosis of prostatic adenocarcinoma.

This study was conducted to explore the feasibility of using the lead level in the hair of children as a screening test for lead intoxication of children and as an indicator for environmental pollution. Lead concentration of hair was measured for 268 seven to nine-year-old elementary school children in Taegu city (147 children) and Gampo. town(121 children). The lead level in hair was measured by atomic absorption spectrophotometer equipped with a graphite furnace atomizer. The following information was obtained for all children : sex, age, father's occupation and smoking habits, kinds of hair cleaner, fingernail biting habits, and status of the child's hands and clothing. The mean lead level in hair was 8.7+/-2-9 microg/g in the urban area and 7.7+/-2.2 pg/g in the rural area. There were significant differences between two groups(p(0.01). The difference of lead levels in hair measured by cleanliness of the child's hands (clean : 7.4+/- 2.7 pg/g, dirty : 8.2+/- 2.6 pg/g) and child's clothing(clean : 8.0+/- 2.5 microg/g, dirty : 9.3+/- 2.6 microg/g) were statistically significant, but other factors were not significant. In multiple regression analysis, difference of residency and age were significant variables for lead level in the hair of children. These findings suggest that measurement of lead level in the hair is a useful method for the screening of the lead intoxication of children and monitoring environmental conditions.

The authors performed the interfascicular nerve grafting in the gap of injured nerves using the microsurgical technique to obtain the accurate coaptation of the fascicles. The authors experienced the 33 cases(26 patients) of the interfascicular nerve grafting in the median(11), ulnar(9), radial(2), common peroneal(3) and digital(8) nerves at the Department of Orthopaedic Surgery, College of Medicine, Kyung Hee University from Jan. 1980 to June 1984. The patients were followed up from 12 to 26 months (average 20 1/2 months). The following results were obtained; 1. The shorter the length of the donor nerve and the younger the age of the patients are, the better the recovery of the nerve function is. 2. The medial and lateral cutaneous nerves of forearm as donor nerve are suitable as well as the sural and superficial radial nerves. 3. The end result of each patient was evaluated by Seddon's classification. The excellent motor recovery was 72.0% (18/25) and the excellent sensory recovery was 81.8% (27/33). 4. The interfascicular nerve grafting is an excellent method in treating the widely separated,severed peripheral nerve injury.

Forty five gonococcal patients were treated with spectinomycin hydrochloride at the Department of Urology, St. Mary's Hospital from August 1. 1972 to December 32. 1972. All patients were male and confirmed as acute gonorrheal urethritis by gram stained smear or culture. The cure ability in this series was very satisfactory The results were as follows; 1. Gram negative ;intracellular diplococci was controlled in 29 patients (96.7%) among 3O patients with pure gonococcal infection with a single injection of spectinomycin hydrochloride. 2. Gram negative intracellular diplococci was controlled in 14 patients (93.3%) among 15 patient with mixed infection with a single injection of spectinomycin hydrochloride. 3. Only two in all patients were controlled in gram negative intracellular diplococci with repeat injection. 4. 4 patients (13.3%) of the pure gonoccoccal patients with a single injection were converted to non-specific urethritis, which were treated with combination of other antibiotics. 5. 5 patients (33.3%) of the mixed infected patients with a single injection were converted to nonspecific urethritis, which were treated with combination of other antibiotics. 6. No side effect was noted in all patients.

Six cases of juvenile diabetes mellitus who were admitted Busan National University Hospital from Jan., 1976 to Dec., 1979 were observed. The result were summarized as follows; 1) The mean age of onset was 11 & male to female ratio was 2 to 1 with male preponder ance. One half cases were occrred during spring. Two had family history of diabetes inclu ding one case of diabetic sibling. 2) Polyuria and polydipsia were noted in all cases as initial symptoms and symptoms of polyphagia(4), weight loss(4), weakness(3), enuresis(2) and altered consciousness(2) were noted in order of frequency. More rapid onset, more severe clinical features were observed. Associated illness were noted 4 cases of infection & 1 case of cataract. Mean blood glucose level was 430mg%, urine sugar above 3+and S.G. of urine was above 1.030. 3) Three cases of ketoacidosis & diabetic coma were occurred on admission. Consciousness cleared in 3 days, and ketonuria disappeared in 2 days after insulin & fluid therapy. 4) Mean duration of admission was 24 days. At discharge, dose of insulin needed was 10 to 50 units/day. Two cases were readmitted due to ketoacidosis and postoperative complication but all cases were not sufficiently followed up.
