2.The Study on the Control of Renin Secretion.
Korean Circulation Journal 1972;2(1):1-19
It is still not well documented what the basic roles for the regulation of renin secretion from the kidney take place. Since the early study on the renal ischemia for the production of hypertension was introduced, the renin-angiotensin system has been regarded as the possible pathogenetic mechanism for the renovascular hypertension. The renin-angiotensin system, however, could be activated by various stimuli, such as, the changes of intrarenal perfusion pressure, the load or concentriation of sodium at the sites of macular densa, the changes of the sympathetic nervous activity and the changes of potassium balance. To investigate the renin-angiotensin system and the influence of sympathetic nervous system on the regulation of renin secretion, the renovascular hypertension was induced in the dogs by constriction of unilateral renal artery, and the plasma renin activity was measured. The sodium load at the sites of macula densa was attained by furosemide, and then the activity of sympathetic nervous system was depressed by reserpine. The plasma renin activity was assayed by the method of Helmer and Cohn. By this bio-assay method, the plasma renin activity equivalent to 1 nanogram angiotensin-II can be measurable and the prepared plasma was found to have still vasopressor activity. The results observed in this experimental work are summarized as follows. 1. The blood pressure reached maximum on the 3rd postoperative day, and declined gradually to the level of preoperative day on the day of from the 6th to 12th day following constriction of renal artery. 3. The plasma renin activity was found to be well correlated with the increase of blood pressure, and then declined to its preoperative level with the reduction of blood pressure. It appears, therefore, that the renin-angiotensin system plays an important role in the pathogenesis of renovascular hypertension. 4. The urine flow rate in normal and reserpinized dogs was the same before administration of furosemide, but its rate was significantly increased in both groups after furosemide. The urine flow rate of reserpinized dogs, however, was significantly lower than that of the normal dogs during the first 5 minutes. 5. The urinary sodium excretion in normal and reserpinized dogs was significantly increased in both groups after administration of furosemide and there were no difference between the two groups. 6. The plasma renin activity of renal venous blood was significantly higher than that of femoral arterial blood in both groups before and after administration of furosemide. 7. The plasma renin activity of reserpinized dogs was significantly lower than that of normal dogs before administration of furosemide. After furosemide, however, the plasma renin activity was significantly increased in 30 minutes in both groups. This increase of plasma renin activity was less prominent in resepinized dogs than in normal. This results would suggest that the intrarenal mechanism regulating renin secretion also requires an intact sympathetic nervous system.

7.Surgical Correction of Epididymal Obstruction.
Korean Journal of Urology 1972;13(2):107-115
During the period of 1964 to 1972, epididymovasoetomies were performed on 53 cases of azoospermias due to epididymal obstruction. They were operated by the technics of the ordinary side-to-side epididymovasostomy with splint, in such a manner that a minute longitudinal opening in the vas was anastomosed to a similar opening in the epididymis at a site where live sperm had been recovered, which was applied on 58 per cent of the subjects, and of the buried side-to-side anastomosis with a splint, wherein longitudinally opened vas ..was actually buried in longitudinally opened head of epididymis, which was attempted on 26 per cent of them. The following data are presented as abstraction of clinical findings and the operation outcomes: l. An average age of the subjects was 35, and that of their wives, 30. 2. An average duration intervening between the beginning of the obstruction and the performance of the operation was 9 years. 3. An average frequency of sexual intercourse per week indicated 2.5 times before the obstruction 2. 2 times after the obstruction, and 2. 1 times after the operation. 4. In the majority of the cases, the post-inflammatory obstructions were found to be the most responsible causes for azoospermia in my present study. That is, non-tuberculous epididymitis (gonorrheal and non-gonorrheal origin) was found in 70 per cent of the subjects and tuberculous origin, 25 per cent of them respectively. 5. Success rate of non-tuberculous epididymitis group is higher than that of tuberculous epididymitis counter part 6. Success rate of the buried technic group is higher than that of the ordinary technic group. 7. Success rate of bilateral oozes with sperm group is higher than that of unilateral oozes with sperm or no oozes group. 8. A total of 53 cases was operated upon for curing the obstructive azooepermias. Poet-operative semen analyses were carried out on 43 cases out of the 53. Sperm appeared in the ejaculates of 17 cases out of the 43 in repeated sperm tests 3 weeks following the operation. Accordingly, successful operations were showed in 40 per cent of the 43 cases. Seven pregnancies(16%) followed the operation. 9. The writer believes that epididymovasostomy could be said to be a worthwhile procedure for the cases of asooapermia due to the obstruction of globus minor with normal spermatogenesis. The prognosis is always good whenever the indications are strictly followed.

9.Electrocardiographic Diagnosis of Left Ventricular Hypertrophy by Scoring System.
Korean Circulation Journal 1977;7(1):1-8
Three point scoring systems for the diagnosis of left ventricular hypertrophy were studied referring to positivity as well as false positivity in 100 cases of clinically proven LVH and 100 cases of healthy persons. 1) By Estes' scoring system 98% of LVH cases were diagnosed as LVH. There was 14% of false positive rate in healthy person. 2) By Romhilt and Estes' scoring system, 58% of LVH cases were diagnosed as LVH. There was 1% of false positive rate in healthy person. 3) By Skjaggested and Kierulf scoring system, 81% of LVH were diagnosed as LVH. There was 17% of false positive rate in healthy person. 4) Point scoring systems were more accurate in electrocardiographic diagnosis for LVH than any other conventional criteria. Among the reported scoring systems, Estes scoring system was considered the most useful as well as accurate one.
