The occupational skin diseases in an industry of silk reeling located in Daegu city of Korea were analyzed by inspection through a mass survey for improving the workers' health, November, 1975. The subjects, 177 persons were all females, and were distributed at 18-38 years old. About two thirds were under 25 years old. The mean age was 23.6 years. The incidence of skin diseases was about 53%. It was generally divided into groups; -the epidermic changes of those were most frequent, 47.5%, the allergic reactions were 14.7%, and athlete's foot was only four cases, 2.3%. Most frequent signs of epidermic changes was the wornout nail, 32.3%; and the keratolysis, 28.8%; and the callus, 15.3% were followed in order. Theses were significant in five per cent level between the sections of the silk reeling and the manufacturing;-Allergic reactions and worn-out nail were more frequent in the manufacturing group than the silk reeling, and keratolysis and callus were inverted proportionally. Allergic reactions were occurred within a few months from first entrance time, and it was more frequent in the group exposed to same allergen in the past than the continuing group form first. Most of the appearing sites of theses were hands, and infrequently, it was occurred in the face, neck, trunk, knee and feet. These epidermic changes except allergic phenomena were appeared in the fingers, palmal and dorsal surface of hands frequently contacted. But these changes and allergic reactions were generally combined with two or more kinds.

This is a result of clinical examination for workers working with Chromic acid and Chromium compounds in the plating room of their companies. I selected two companies that the plating process and the kinds of plating were similar. One (SW Co.) was more or less improved the operating environment with the ventilation machine so on and another (SR Co.) did not it so. The former was examined at March 29th 1977, the latter was at June 28th 1976. But the respiratory communicable diseases, flue or common cold so on were not spreaded there at that time. The clinical aspects were compared between the group of SW, and SR. The swelling and hyperemic signs of nasal mucous membrane and the experience of nasal bleeding were about 50%, generally, in all the groups. The following problem was dizziness or vertigo. The nasal signs in the group SW (improved ventilation of the room air) were relatively weak, but in another, it was come what severe;-there was necrotic sign with thick nasal clast. They were only used of gauze mask when the vapors of various solvents were deeply full in the room. And there was very high rate of bronchial signs, sputum or coughing in the group of SW improved ventilation so called, than another one. I suppose that it means chronic inflammatory change of the bronchial mucous membrane with deeper signs, due to the individual protectors were carelessly or not used according to the improving of the operating environment. Theses nasal signs mentioned the above were not nearly in the other groups had not been done the Chromium plating. The status of RBC, Hb and Ht, of urine protein and urobilinogen were mostly in normal range. But the number of WBC was more or less showed with a positive cor-relation to the working duration.

Forty-nine children between the ages of 2 and 10 years, treated conservatively for fomoral shaft fracture, were studied clinically and radiographically to access the complications and related factors. They had an average follow-up of 48.8months(range, 12 to 77months). 35 percent of the patients had significant associated injuries. Leg length discrepancies of 10mm to 20mm are observed in 5 cases(10%) of the patients. The average overlap of bone ends at union was 6.5mm. The average growth acceleration was 8.8mm regardless of sex, age, upper limb dominance, fracture site or shape, but was promoted by overriding of the fracture ends at union, There were 16 cases(32%) of excessive angular deformity of 10° to 25° after union. However all deformities were remodelled enough to give normal alignment of the joint surface. The growth plate played on important role in the remodelling process.

This survey was carried out on about 240 prostitutes for American soldiers in Bong-Deok Venereal Diseases Clinic, Daegu Korea, through 2 times for two months from October and November 1974. The culture method was used identifing Neisseria and Mimeae species carbohidrate fermentation test was ferformed with phenol red broth base added human serum. Resistance test was informed with disc method in chocholete agar plate. The discs were made by Jong-Geon Dang Pham. Co.. Seoul, Korea. The carrierate of Neisseria genorrheae was 9.8% and there were relatively many carriers of Mimeae. If the direct smear is used only in microscopic diagnosis, it is easily confused to differentiate Gonococcus and Mima, a kind of coccobacilli. Gonococcus resistance to penicillin G was found in one out of 5 cases tested. The most of Mimeae was resist to penicillin G, but the broad spectrum antibiotics such as chloramphenico1 and gentamycin etc was moderatly sensitive.

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.

Our present knowledge of impetigo contagiosa extends from its first description as a separate clinical entity by Fox in I864, and the proof of its bacterial etiology by Radcliffe-Crocker in 1881. Both staphylococci and streptococci have been discovered from the lesions, but the relative preponderance of each varies greatly, and reports are contradictory. Seventy-eight patients with impetigo contagiosa were studied bacteriologically in order to ascertain the primary etiologic agent. Also, a susceptibility test (Bauer- Kirby method) was done on the isolated organisms with 7 antibiotics which are used frequently in the clinical field. Specimens obtained from the skin lesions were cultured and organisms were isolated. They were identified by various biochemical and serological tests. A DN ase test, a carbohydrate fermentation test, and a coagulase test were done for the isolated staphylococci. A bacitracin disc method and a precipitin test(Lancefield method) were done for the isolated B-hemolytic streptococci. The results were as follows: Fifty-six cases(71.8%) were infected by staphylococcus only. Twenty cases(25.6%) were infected by a mixture of staphylococcus and p-hemo- lytic streptococcus. Only 2 cases(2.6%) were infected by B-hemolytic streptococcus alone. All 76 strains of staphylococci were identified as coagulase positive staphylococci. Among the 22 strains of B-hemolytic streptococci, 15 strains were identified as group A and remaining 7 strains were identified as group B. Coagulnse negative sta,phylococcus was not found. In the susceptibility test to 7 antibiotics, staphylococci showed susceptibility to lincomycin, erythromycin, cloxacillin, and chloramphenicol, and resistance to tetra-cycline, penicillin, and ampicillin. Streptococci showed susc.ptibility to all of the above antibiotics except tetracycline. From the results of this experiment, it was concluded that the primary etiologic agent of impetigo contagiosa was coagulase positive staphylococcus and streptococcus for the most part can be considered as a secondarily infecting agent. Coagulase negative staphylococcus apparently is not implicated as an etiologic agent of impetigo contagiosa. The results of the antibiotic susceptibility tests would seem to indicate that the use of such antibiotics as tetracycline, penicillin, and ampicillin is not indicated in the treatment of impetigo contagiosa.

In the present study, tap water iontophoresis as a method of treatment of palmoplantar hyperhidrosis was evaluated. Eighteen patients, twelve males and six females, with singnificant palmoplantar hyperhidrosis were treated on every weekday for 2 weeks. The hand and foot of the same side were randomly selected for the treatment by tap water iontophoresis according to the the method described by Levit. The selected hand and foot were immersed in a pair of pans containing tap water and exposed to 30V and 3 to 14mA of direct current for 20 minutes. The results obtained were as follows . Among 18 patients treated, 14(77.8%) accomplishei3 sufficient control of hyperhidrosis after 6 12(average 9.1) treatments. Two patients showed a moderate response and one weak response. One patient showed no response. Several patients experienced untoward effects such as mild itching, erythema, tingling sensation, exfoliation, compensatory hyperhidrosis, but the discomfort was not so severe as to stop the treatment

As a link of chain study program of school health, a survey was made up by the screening test with audiometry for hearing disturbance on 18,675 high school students who are mainly aged in 15-19 years from November 5.1969 to October 30. 1970. The results obtained were summarized as follows. According to our criteria as table 3, the rates of the profound , the severe and the moderate who required the appropriate hearing aids were 0.02%, 0.03% and 0.14% respectively : the cumulative percentage was 0.197. When the marginal, 0.23% should be included the cumulative rate was 0.41%. But there was no significance by sex and school classes. If we will make the special classes for them one class would be estimated out of 10,000 persons when a class is formed with about 15 persons. Otherwise when we examined that according to each ear of persons, the rates of the profound, the severe and the moderate were 0.17%, 0.22% and 0.33% respectively and their cumulative perventage was 0.72. There was no significance also by sex and age. By the way, the rate of hearing disturbance in urban high school students tended to lower than rural. And the perceptive disturbance was higher than rural in rate. The conductive disturbance tended to oppose in comparison with the above.
