1.Studies on Total Exchangeable Sodium and Plasma Volume in Hypertension.
Korean Circulation Journal 1975;5(2):1-20
Total exchangeable sodium and plasma volume were measured to evaluate role of sodium in hypertension by radioisotope 24 Na and Evans blue in 25 patients with essential hypertension, 10 with malignant hypertension, 5 with renal hypertension and 15 normal controls. The results obtained are as follows. 1. The total exchangeable sodium content was 35.8+/-3.5mEq/kg in normal controls, 35.6+/-2.7mEq/kg in essential hypertension and 36.2+/-3.5mEq/kg in renal hypertension revealing no statistical significance in difference. In malignant hypertension, it was 44.9+/-2.0mEq/kg and it was markedly elevated than in normal controls. 2. Plasma volume in normal controls was 44.0+/-4.7ml/kg. In essential hypertension there was two groups, one (group II, 35.2+/-5.6ml/kg) was slightly lower than the other (group I, 43.2+/-4.8ml/kg). In malignant hypertension, it was 56.9+/-7.5ml/kg revealing significant increase than in normal controls. 3. Changes of the total exchangeable sodium content was observed after the administration of hydrochlorothiazide 50mg in normal controls and essential hypertension. In normal controls there was no statistical significance in reduction. In essential hypertension, initially low salt group (group II) showed no significant reduction and the other group (group I) showed significant reduction with depression on blood pressure. 4. Long term therapy with hydrochlorothiazide 50mg for 2~3 months in the group of hypertension who responded well with short term therapy (group I), the contents of exchangeable sodium reduced significantly than normal controls and the antihypertensive effect was sustained. 5. The reduction of plasma volume with hydrochlorothiazide in essential hypertension are similar as changes of total exchangeable sodium. 6. In cases of low salt diet 4gm of daily salt intake, there was similar results as diuretic therapy in exchangeable sodium. 7. In patients who responded well to antihypertensive effect of hydrochlorothiazide or low salt diet (group I), salt loading of 10gm daily showed an increase of total exchangeable sodium and an elevation of blood pressure with statistical significance.

14 cases of femoral shaft fractures were treated with cast-brace for two years from June, 1974 to June, 1976 at the Department of Orthopedic Surgery, College of Medicine, Seoul National University Hospital. The results were as followings; 1. Of the 14 cases, eleven cases were male and three were female, and they were between 18 to 51 years of ages. 2. The fracture site was accounted that three of 14 cases were at the distal one third of the femur and the other eleven at the mid one third with four cases being comminuted. 3. 7 cases were treated with cast-brace initially, and the other 7 cases were secondarily treated, because of being complicated. 4. The average time of fracture healing was 14 weeks in the cases with cast-brace which is compared with 20 weeks of spica-cast control group in the same period. 5. One of 7 cases treated primarily developed shortening and angulation, which was corrected by open reduction and internal fixation.

Historically, cerclage has gained a bad reputation because of the early unfavorable results with the Parham band and subsequent further poor results with wire cerclage. The treatment and management of elderly patients with fractures through osteoporotic bone is fraught with difficulties. The standard methods of internal fixation are not always satisfactory as metal plates and screws and intramedullary nailing do not hold well in osteoporotic bone. To overcome this problem, a system of straps and plates has been devised. We experienced 3 cases of femoral fractures using nylon cerclage system, such as the segmental fracture, oblique fracture in osteoporotic patient and the fracture below a hip prostesis. The end-result was satisfactory.

PURPOSE: There have been numerous retrospective and uncontrolled study of laparoscopic appendectomy. Although most of these have concluded that the laparoscopic appendectomy is at least as good as open appendectomy, there has been considerable controversy as to whether laparoscopic appendectomy is superior. METHODS: We performed total 47 cases of laparoscopic appendectomy (LA) during one year from January 1997 to December 1997 and these were compared with 50 cases of open appendectomy (OA) in same period to assess the clinical usefulness. RESULTS: The sex, male to female ratio and severity of appendicitis were similar in both groups. The anesthetic time was longer in the LA group (P<0.05) but operative time was similar. Gas-passing time and diet-intake time in postoperative period were earlier in LA group (P<0.05). The LA group required less analgesics in postoperative period. In LA group, no case was converted to open appendectomy and overall complication rate was lower in LA group but this was not statistically significant. Among the postoperative complication, the wound infection rate was absolutely lower in LA group (P<0.05). The diagnostic rate for acute abdomen including acute appendicitis was superior in LA group, especially in reproductive women. The hospital stay was shorter in LA group (P<0.05) and hospital charges was not different in both group. CONCLUSION: Laparoscopic appendectomy offers considerable advantages over open appendectomy because this has ability to reduce postoperative complications and shorten recovery times and is useful for detecting the cause of acute abdomen other than acute appendicitis. So we expect this technique will be alternative operation or new standard operation in selected cases for suggestive acute appendicitis.

BACKGROUND: To assess the clinical utility of new DNA extraction method, the authors attempted PCR using mycobacterial DNA extracted by Chelex 100 ion exchange resin method for 63 clinical samples in patients with pulmonary tuberculosis and compared with proteinase K method, simultaneously. METHODS: We used Chelex 100 ion exchange resin for preparation of DNA. Decontaminated sputums were mixed with resin and incubated at 56degrees C and 100degrees C without opening tube. After centrifugation, supernatants were used directly as template for PCR. 245 bps in primary PCR and 188 bps in nested PCR were amplified and analysed by agarose gel electrophoresis EtBr staining. RESULTS: Chelex 100 ion exchange resin method is more simple, rapid and reliable than proteinase K method, and during sample preparation, carry-over contamination loss of amplificated DNA, influence of organic solvents and cross-contamination are diminished. The results of PCR products are interpreted more distinctively in Chelex 100 ion exchange resin method than proteinase K method. CONCLUSIONS: In the basis of the results, it could be suggested that extraction of mycobacterial DNA by Chelex 100 ion exchange resin is more simple, rapid reliable method than that of conventional method for detection of mycobacterial DNA in patients with tuberculosis by polymerase chain reaction.
