A total of 42 vas anastomoses was performed on experimental animals and successful anastomoses were obtained 19 of the cases and the over-all rate of success was approximately 46 per cent. But 13 dogs in total of 21 dogs were found to be patent in at least one side of vas, or about 65 per cent of total dogs were restored their fecundity. Splinting materials used in this comparative study are chromic catgut, stainless steel wire, dermalon and polyethylen tube, and dermalon has been proved as the most excellent splinting material among thembecause it is no figid but plable and makes no tissue reaction in the vas. Successful anastomosis of vas deferent is affected by many factors. Among these, an inadequate splinting material has been considered as the most important causes of failures. But it should seem that minimal dissection of the tied points of vas as satisfactory approximation of the free ends of vas exert very important effect upon the successful anastomosis as the splinting material does. Consecutive four successful anastomosis of human cases are highly satisfactory results and are very encouraging even in a small series of cases of the present study.

About 60,000 men were undergone voluntary sterilization by the 497 designated doctors during the period from 1962 to October 1965 by the government subsidy program. Besides these numbers more than 15,000 private cases were sterilized by private doctors during the period from 1960 to 1964 in Korea. A general comprehension of the sterilization operation for motivation of customers was illustrated. An analysis of the social history and background of the sterilized men were made on the author's private group and the subsidized group. The most common occupation of the private group was commerce and that of the subsidized group was africulture. The duration intervening between marriage and sterilization indicated 13.6 years in the private group and 16.7 years in the subsidized group. An average age of the sterilized men showed 40 and that of their wives 35. An average number of children of the private group showed 4.7 while that of subsidized group indicated 5.3. Sexual drive following the sterilization was not changed in 81 per cent of the private group and in 71 per cent of the subsidized group. Decrease in sexual activity was revealed in 5 per cent of the private group but in 11 per cent of the subsidized group. General health after the sterilization was not changed in 83 per cent of the private group and in 70 per cent of the subsidized group. Decrease in general health was noted in only 6 per cent of the private group but in 11 per cent of the subsidized group. Frequency of sexual intercourse per week of the private group indicated 1.95 times preoperatively and 1.88 times postoperatively whereas that of the subsidized group revealed 2.27 times preoperatively but 1.99 times postoperatively. In regarding the sexual feeling of their wives, more than 87 per cent of the private group showed no change before and after the operation while 71 per cent of the wives of the subsidized group were not changed. Very few wives of the private group complained of some decrease, but 10 per cent of the subsidized group complained decrease. The time lost from work after the sterilization was about 2 days in the private group while about 8 days in the subsidized group. About 93 per cent of the private group were satisfied with the sterilization but 2 per cent of them did not feel happy after the operation. In the subsidized group 88 per cent were satisfied with the operation but 10 per cent were not satisfied. All of the private group and 80 per cent of the subsidized group would recommend the sterilization method to their friends. Untoward effects on sexual drive and general health are found to be higher in the subsidized group than in the private group. These outcomes are partly due to low edcation and low income of the subsidized group compared with the private group and partly due to unsatisfactory operative technique of the designated doctors. Psychological studies by means of MMPI conducted on 20 sterilization neurosis patients and the results were compared with the control nonvasectomized group. The sterilized group had definite psychological instability so that a preoperative psychological interview is found to invariably be necessary to prevent the sterilization neurosis. It is concluded by this preliminary clinical survey of the vasectomized cases through the author's private system and the government subsidy program that the few who told to decrease in sexual capacity and general health were outnumbered by those reporting an increase. The majority of the cases told of no change. The changes noted by a small proportion of patients appeared to be chiefly of psychological origin because there was no physiologic reason why the operation of vasectomy should causes sexual excess or decrease.

An anastomosis of the vas deferens was performed on 17 patients since 1963.Semen specimens were examined repeatedly in 15 cases of the series after periods from 2 to 24 weeks following removal of the splint. The fifteen were found to have viable sperm in their ejaculates but one of these patients subsequently became azoospermic again. Three of the fifteen cases had some degree of deteriorated effects after the previous vasectomy but they were free of the complications following the successful anastomosis of the vas deferens. Operative rechnics were discussed. In this series 2-0 dermalon was used as a splint in 15 cases and stainless steel wire was used in 2 cases. Liothyronine was given to 16 of 17 patients at or before the operation for periods from 1 to 6months. Over-all successful results would indicate about 65 per cent of the cases operated in the literature. The author's small series indicates that more than 90 per cent of the operated cases could be successful in this operative procedure from the cytological point of view.

Serological survey, using methylene blue dye test for toxoplasmosis was carried out upon 395 normal population, 21 cases of uveal lesions, and 95 cases of acute febrile and chronic systemic diseases. Toxoplasma gondii preferred for this test was "Anyang straio" from Veterinary Researh Anynag, Korea in March 1968. The results were as follows: 1. In normal population 9.62 per cent of the sera examined showed positive titers of 1:16 or above in adult and 1:8 or above in children. 2. The positive in serologic survey was prevalent 3rd to 5th decades of both sex. 3. 4 out of 21 cases of uveal lesions were positive of which titers showed 1:64 or above in adults and 1:32 in a girl. 4. In 95 cases of acute febrile and chronic systemic diseases 4.2 per cent of the sera examined showed positive titers of 1:16 or above.

Mass screening of cardiomegaly by chest X-ray in 144,021 (male 55,491, female 88,530) students of primary, middle and high school (6~17 years of age) in Seoul was performed and electrocardiograms of 217 cases of cardiomegaly were studied. The results were as follows; 1) Cardiomegaly (cardiothoracic ratio over 0.5) was seen in 0.19% of each sex and it was higher in middle and high school ages (12~17 years) than primary school ages (6~11 years). 2) Incidences of abnormal electrocardiogram in cardiomegaly were 59.5% in male and 54.7% of female students. Major abnormal electrocardiograms in cardiomegaly were right ventricular hypertrophy (24.8%), left ventricular hypertrophy (11.6%), biventricular hypertrophy(4.8%), complete right bundle branch block (7.7%), incomplete right bundle branch block (8.7%), first degree A-V block (5.8%) and premature beat (4.3%). 3) Left ventficular hypertrophy was seen most frequently in high school ages (15~17 years) and decreased with decreasing age. Right ventricular hypertropy was seen most frequently in primary school ages (9~11 years) and decreased with increasing age. Biventricular hypertrophy was seen most frequently in primary school ages (6~8 years) and decreased with increasing age. 4) Complete and incomplete right vundle branch block were seen commonly in 12~17 years of age and first degree A-V block in 9~11 years of age.

OBJECTIVES: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. METHODS: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain; severe gain), cigarette smoking (quitter; non-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. RESULTS: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0.001), but negatively with smoking (p=0.004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or non-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). CONCLUSIONS: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

A case of orbital injury with a plastic chopstick accompanied by meningeal irritation signs was presented. A 34-year-old house-wife was admitted to our clinic complaining of vision loss, proptosis and dull ocular pain in right eye on March 11, 1976. 17 days before admission she was stabbed on the right orbital region with a plastic chopstick. The clinical finical findings Were recorded normal in left eye. The right eye showed zero in vision, proptosis, fixed eyeball with total ophthalmoplegia and exposure Keratitis. On the 2nd hospital day a broken plastic chopstick, 9.5 cm in length, was carefully removed from injured site by exploratory eperation. In that afternoon meningeal irritation signs, vomiting and neck stiffness was abruptly developed. The laboratory findings of the cerebrospinalfluid revealed inflammatory signs. After having been administered massive antibiotics (crystalline penicillin, bayrena, and chloramphenicol) systemi-cally for 17 days, she was recovered from meningeal irritation signs containing remission of inflammatory findings of cerebro spinal fluid examination. On the 21st hospital day, 39 days after injury, the optic disc was seen totally pale. On the 25th hospital day she was discharged, at which right eye showed clear in cornea, totally pale disc, and total ophthalmoplegia with ptosis. When she returned about 5 months after discharge, the right eye revealed much regressed ptosis, superficial corneal opacity with loss of corneal sense, ocular motility limited in superolateral direction, fixed and dilated pupil and still pale disc. Authors attempt to evalurate this case throlgh the related literatues.

Authors observed the antihypertensive effect of debrisoquin sulfate in 35 cases of essential hypertension and following results were obtained. 1) Results of short term control of blood pressure with debrisquin in 35 hypertensive patients revealed good control in 74.3%, fair in 14.3%, poor in 5.7% and failure in 5.7% of cases. Significant reduction of blood pressure was achieved in 7 of 9 cases of hypertension with addition of hydrochlorthiazide to debrisoquin. 2) During long term therapy with debrisoquin (duration of average 3.9 months), good control cases were slightly reduced(good in 58.6%, fair in 24.1%, poor in 6.9%, failure in 10.3%). But average effective dose of debriioquin was not increased significantly. 3) Antihypertensive effect of debrisoquin was slightly reduced in the cases of severe hypertension, hypertension of over 10 years duration and complication of cerebrovascular accident. 4) The side effects during treatment with debrisoquin were dizziness in 31.4%, headache in 11.4%, dry mouth, blurred vision, general weakness, insomnia in 8.6% respectively. There were no side effects in 48.6% of cases.

PURPOSE: Neonatal hyperbilirubinemia has benign courses in most cases, but the possibility of toxicity of hyperbilirubinemia required courses examination of every newborn infant to identify the severity of hyperbilirubinemia progress. This study aims to see how the body surface area of newborns influences the decline rate of serum bilirubin level in conventional phototherapy. METHODS: Based on the charts of the Pediatrics Department, Dae-Dong Hospital from January 2003 to December 2006, we analyzed 168 neonates diagnosed as neonatal hyperbilirubinemia (serum bilirubin > or =15 mg/dL) in retrospective way. We excluded newborn infants under 37 weeks of gestation and under 2,500 g birth weight and classified neonates into four groups by the calculation results of body surface area:males above 75 percentile (group A), males below 25 (group B), females above 75 (group C), and females below 25 (group D). RESULTS: Out of 168 samples, the number of group A, B, C, D was 30, 20, 20, 15 respectively. In conventional phototherapy, the mean decline rates of serum bilirubin of group B and D recording 2.09 mg/dL/day and 1.77 mg/dL/day, were significantly faster than those of group A and C recording 1.63 mg/dL/day and 1.41 mg/dL/day (P<0.01). No significant differences were found in different duration of phototherapy between groups below 25 percentile and those above 75 in both genders. CONCLUSION: In conclusion, body surface area influences of infants the decline rate of serum bilirubin level in conventional phototherapy.

PURPOSE: The objective of this study was to investigate the influence of hospital nurses' self-leadership, communication skill, and self-esteem on the quality of nursing service. METHODS: The participants, 230 nurses working at a general hospital in Seoul, completed a cross-sectional descriptive questionnaire survey between January 17 and 28, 2014. The collected data were analyzed using the SPSS 19.0 program for descriptive statistics, t-test, one way & two way ANOVA, correlation, and multiple regression analysis. RESULTS: Nurses' self-esteem and communication skill had significant main effects on self-leadership and the quality of nursing service, but the interaction effect of the two independent variables was not significant. Variables that significantly influenced the quality of nursing service were self-leadership, communication skill, self-esteem, and career longevity. The explanatory power of these variables for the quality of nursing service was 54.4%. CONCLUSION: Findings indicate a need for education programs for nurses which are designed to promote communication skill and enhance self-esteem and self-leadership skills which will in turn enhance the quality of nursing service.
