Since the Plasma-Renin Activity (PRA) value varies by many factors such as amount of sodium in-take, diuretics and posture, the basal PRA with double stimulated PRA measurement is most widely used. However the method of the study is different according to investigators and especially the PRA study in out-patient is not easy. Author attempted to establish an easy and reliable method of PRA study in out-patient and their data were compaired with those of in-patient by the study of 38 normal cases in 207 hypertensive patients. Twenty four hours urine and overnight urine sodium measurement showed that the overnight urine sodium was about 45% of that of twenty four hour urine. More than 70mEq of overnight urine sodium is considered to be borderline to neglect sodium intake for study. The PRA of normal adult was measured at 30 minutes and one hour rest in supine or sitting position after arrival to hospital. There were minor increase of PRA after 30 minutes and one hour rest than basal PRA which will not confuse the evaluation of PRA. After Lasix 40mg and 20mg intravenous injection with walking respectively, the PRA changes were measured in 30 minutes, 1, 2, and 3 hours in normal adult. The results appeared that Lasix 20mg intravenous injection and 1 hour walking double stimulation is suitable method of PRA stimulation test in out-patient clinic. The Lasix 40mg I.V. and 2 hour walking stimulation test is considered to be suitable method of PRA stimulation test in ward patient. With above study, the following method of PRA study in out-patient clinic is recommended; 1) Overnight fasting and overnight urine collection for urinary sodium measurement 2) Patient should visit hospital in fasting state and take rest for 30 minutes in supine or sitting position and thereafter take blood sample about 5-10ml as out-patient basal PRA. Inject Lasix 20mg intravenously and walk for 1 hour and take blood sample again as double stimulation test. As double stimulation test of PRA for in-patient, Lasix 40mg l.V. and 2 hours walking is recommended. By using above method, the basal PRA in clinic in 16 young normal adults was 2.30+/-1.02(0.70-3.47)ng/ml/h sitting rest and 1.76+/-1.21(0.1-4.03)ng/ml/h in supine rest. In 47 non-hypertensive ward patients who will not have any abnormality in PRA, the 24 hour urinary sodium was average 221mEq and the basal PRA was and the basal PRA was 1.46+/-0.89(0.30-3.75)ng/ml/h. In outpatients with essential hypertension without complication, the average basal PRA was not different from that of normal adult. However male ward-patients with essential hypertension without complication had slightly higher average PRA than normal adult. The distribution of low(<0.56ng/ml/h) average(0.57-2.35ng/ml/h) and high(>2.36ng/ml/h) renin groups in essental hypertension showed higher incidence of high renin group in male ward-patients. But in out-patients with hypertension, the low renin group of patient was high. Relatively low normal value of PRA in this study may be due to high sodium in-take. The higher incidence of high PRA group in essential hypertension of in-patients may be due to the difference of hypertensive status between out-patient and in-patient.

BACKGROUND: Statistical errors have been noted in a large percentage of articles appearing in medical journals. Their incidence in the Annals of Dermatology and the Korean Journal of Dermatology, however, has not been studied. OBJECTIVE: The purpose of this study was to evaluate the accuracy of statistical methods in the Annals of Dermatology and the Korean Journal of Dermatology. METHOD: Original papers using the t test in the Annals of Dermatology(AD) and in the Korean Journal of Dermatology(KJD) from January 1990 to July 1994 were analyzed for correctness of statistical methods. RESULTS: Of the 376 original papers in the period considered, 78(20.7%) presented t tests and 43(55.1%) of these also contained some errors. Of the 9 papers from the Annals of Dermatology, 4(44.4%) included at least one error. Of the 69 papers from the Korean Journal of Dermatology, 39(56.5%) included at least one error. CONCLUSION: Misuse of statistical methodology may not be uncommon in the two Korean Dermatology journals, and it would be prudent to give more attention to statistical methodology.

Os Subtibiale, inconstant bone over the tip of the medial malleolus, is the very unusual findings and extreme rarity of the condition. We experienced a case of Os subtibiale in a 24 year old man who complained pain and tenderness an the bilateral medial malleolar region. The patient was treated by excision with satisfactory result.

The echocardiographic results obtained from normal group(910 cases), borderline hypertention group(78 cases), define hypertension group(182 cases) and hypertensive heart disease group(55 cases) in Heart Center, Paik Hospital, Inje Medical College, Pusan, Korea between September 1985, were as followings; 1) LVDeD, 5.94+/-1.07cm in hypertensive heart disease group was significantly increased compared with 4.93+/-0.64cm in normal group, 4.92+/-0.73cm in borderline hypertension group and 4.90+/-0.64cm in define hypertension group. LVSeD, 4.86+/-0.98cm in hypertensive heart disease group was significantly increased compared with 3.24+/-0.58cm in normal group, 3.21+/-0.52cm in definite hypertension group. 2) LVDeV/s, 180.26+/-84.76ml/m2 in hypertensive heart disease group was significantly increased compared with 86.13+/-37.34ml/m2 in normal group, 86.26+/-41.02ml/m2 in borderline hypertension group and 83.78+/-30.86ml/m2 in definite hypertension group, and LVSeV/S, 97.51+/-55.67ml/m2 in hypertensive heart disease group was significantly increased compared with 25.28+/-13.25ml/m2 in normal group, 23.68+/-14.62ml/m2 in borderline hypertension group and 24.02+/-14.36ml/m2 in definite hypertension group. 3) There was no significant differance of SV/S, between 61.50+/-26.02ml/m2 in normal, 63.98+/-30.86ml/m2 in borderline, 63.06+/-22.96ml/m2 in definite hypertension group and 61.82+/-30.67ml/m2 in hypertesive heart disease group.

In order to understand the tissue responses of albino rat host against Paragonimus iloktsuenensis infection, the histopathological changes of the spleen and the lungs in 6 experimental groups of rats were observed in relation with the growth, maturation and migration of this lung fluke. Rats of the experimental groups, each group consisted of 5 rats, were infected with the metacercariae of P. iloktsuenensis which were isolated from brackish water crab, Sesarma dehaani, and were kept for 3 days, 3 weeks, 4 weeks, 7 weeks, 10 weeks and 14 weeks of infection period. Peripheral blood smear slides for the differential leukocyte count were prepared and also worm collection was completed immediately after the infection period. Paraffin sections of the spleen and the lung tissue were stained with hematoxylin-eosin and methyl-green-pyronin (MGP) stain. Those materials from the experimental groups were examined in comparison with the materials obtained from control group, with special reference to immunologic aspects of host response. The results obtained were as follows: The counts of large pyroninophilic cell (LPC) in the periarterial sheath of spleen were rapidly increased in earlier period of infection, and those of peribronchial lymphatic tissue started to increase after the penetration of lungfluke into the lungs. The LPC counts of both the spleen and the lungs were on the decrease in conjunction with the necrosis of the lung fluke in 14th week of infection. On observing differential leukocyte count of peripheral blood smear, the fluctuation of lymphocyte count was proportional to that of LPC count, and the lymphocyte count was consistently higher than that of normal rats. On the other hand, neutrophil count of experimental group showed reciprocal relation to the LPC counts. The nature and characteristics of pulmonary lesion produced by the P. iloktsuenensis were just the same as those produced by P. westermani. The lesions were represented by thick and fibrosclerotic cavern, granuloma due to eggs, pneumonic process and cellular infiltrations.
