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.

beta-receptor antagonist as antihypertensive agent has adverse effect such as vasoconstriction, bronchoconstriction and aggravation of atherosclerosis. So beta-receptor antagonist with alpha-receptor blocking property has been studied for avoidance of adverse effects of beta-receptor antagonist. Nipradilol, a new beta-receptor antagonist with alpha-receptor blocking property was administrated in 30 essential hypertensive patients for 10 week in order to evaluate the antihypertensive effects and adverse effects. The results were as follows: 1) Nipradilol was effective in 20 patients(67%) on systolic blood pressure 22 patients (73%) on diastolic blood pressure at the end of 10 weeks treatment. 2)Before medication, mean systolic and diastolic blood pressure in sitting position were 160+/-14mmHg and 102+/-18mmHg,and after 10 weeks of medication, mean systolic and diastolic blood pressure were significantly declined to 143+/-22mmHg and 89+/-12mmHg(p<0.001). 3) There was no significant change in pulse rate, from 78+/-12 beats per minute the beginning of the treatment to 75+/-11 beats per minute after 10 week of treatment. 4) There was no significant changes in sodium, potassium, GOT, GPT, bilirubin, alkalin ephosphatase, BUN, creatinine, LDH, CPK and lipid. 5) The adverse effects of nipradilol were bradycardia(7%), dyspnea(3%), chest discomfort(3%) and headache(3%). In summary, nipradilol seemed to be effective antihyertensive drug in treating mild to moderate hypertension.

Cysts of the iris may be primary lesions of either epithelial or stromal in origin, or secondary lesions after trauma or surgery. The stromal cyst is usually of primary lesion, although it could be secondary as shown in our case. We report a case of recurrent iris cyst after trauma. The patient was an 8-year-old girl. She had a penetrating injury of the involved eye three years ago. She had a similar iris cyst removed two years before this surgery. Histologically, the cyst was lined by non-keratinizing stratified squamous epithelia and subjacent fibrovascular tissue. Islands of melanin-containing epithelial cells and acellular basophilic degenerating materials were also seen in the lesion. This case represents a stromal epithelial cyst that by history appears to be of post-traumatic etiology.

Common peroneal nerve injury has been reported as the most frequent lower extremity peripheral nerve injury. The peroneal nerve may be particulary prone to direct or indirect injury by penetrating trauma or external compression by it's superficial route to bony prominence of fibular neck. By the development of microsurgical technique, recently epineural repair, fascicular group repair, and interfascicular graft were tried. The authors have experienced five cases microsurgical repair of common peroneal nerve injury around the knee joint from December 1990 to November 1991, and motor and sensory result was relatively good.

A cross-sectional study of 118 car painters and controls of 113 workers was performed to investigate the interrelation between self-reported neuropsychiatric symptom and neurobehavioral performance using Scandinavian Questionnaire 16, Zung anxiety, depression scale and Swedish performance evaluation system (simple reaction time, symbol digit, digit span, finger tapping speed). The typical symptoms characteristic of painter's syndrome were not found and no significant association was found between solvent exposure and !total score of neuropsychiatric symptom but neurobehavioral performance of simple reaction time, symbol digit and digit span had association with solvent exposure. No significant associations were found between total score of neurotoxic symptom, anxiety scale, depression scale and the neurobehavioral performance. In factor analysis, the factor of questionnaire 16 measuring function of memory demonstrated no significant association with the factor of neurobehavioral test items measuring short term memory.

With the advent of improyed external fixation device, femoral lengthening has gained renewed popularity in recent years in the treatment of unequal leg length. Wagner(1971) and De Bastiani et al(1987), among others, have made epochal contribution in this field. During the period from May 1984 to May 1987, 25 patients with leg length discrepancy underwent femoral lengthening using Wagner's or De Bastianis distractable external fixators at the Department of Orthopedic Surgery, Seoul National University Hospital. There were 6 patients below 16 years of age admitted to the Children's Hospital, and 19 patients were 16 years or older. The mean age was 18.2 years, ranging from 3 years to 36 years. The underlying etiology included residual poliomyelitis in 20 patients, epiphyseal injury in 2 patients, congenital short femur in 1 patient, septic hip residua in 1 patient, and cerebral palsy in 1 patient. The mean leg length discrepancy was 4.5cm, ranging from 1.3cm to 7.4cm. The mean length gained was 4.1cm, ranging from 1.8cm to 6.4cm. All except two patients had two stage procedures with iliac crest strut bone graft. The mean time required for radiological consolidation of bone graft was 4.8 months. The plate and screws used for osteosynthesis was removed after the medullary canal has been re-established. Six patients had removal of the plate and screws between 8 months and 25 months after the second stage osteosynthesis. Technical errors included 1 case of incomplete osteotomy which required manual clasis, and another case of faulty insertion of Schanz screws that required reinsertion. Five cases (33.3%) had the minor pin tract infection. Schanz screw breakage occurred in a case of one stage femoral lengthening. Loosening of plate and screws was seen in three cases. One case had delayed union requiring augmentation bone graft. Stiff knee with less than 90°of flexion was encountered in one case. One case sustained fracture of patella during physiotherapy. Despite of a long list of complication, the ultimate goal of leg length equalization was successfully achieved in all the cases.

Fractures of the neck of the femur have always presented great challenges to orthopedic surgeons and still remain as one of the unsolved fracture as far as treatment and results are concerned. With life expectancy increasing with each decade, becoming more and more patients suffering from femoral neck fractures and their sequelae. The objoct of this study is to observe the relationship between the clinical results and the degree of displacement of fracture, degree of osteoporosis and duration between injury and operation in femoral neck fractures treated with multiple pin fixation. The author clinically analyzed 56 patients of the femoral neck fractures treated with closed reduction and multiple Knowles pinning followed by more than 1 year at Korea University Hospital from January 1986 to December 1991. There were 20 male and 36 female. The age of patients were ranged from 32 to 88 years(average:65.1 years) and most commonly occurred in 7th decade (23cases,41%). The most common cause was slip down(44 cases;79%). The most common type of fracture was stage III (48%) following to Gardens classification. The obtained results were as follows; 1. Union occurred in 49 cases(88%). 2. Among fifty-six cases, five cases(9%) of avascular necrosis, two cases(4%) Of non-union, two cases(4%) of malunion and one case of posttraumatic arthritis were occurred. 3. The functional results by Lunceford criteria were excellent in 30 cases(53% ), good in 13 cases(23%), fair in 5 cases(10%) and poor in 8 cases(14%). 4. Unsatisfactory results were noted in Garden stage II or IV, osteoporosis below Singh index 3 and delayed treatment over 1 week. Above results suggest that multiple Knowles pinning in femoral neck fractures offers high union rate and low complication rate, and so is also one of salvaging method of femoral head.
