Recurrent epistaxis is not one of rare symptoms in children, the well-known causes of which are anatomical abnormalities of nasal cavity and systemic bleeding tendency. but, in the majority of cases of recurrent epistaxis, it is usually very difficult to find out their underlying causes, so that the treatment is only symptomatic control of nasal bleeding whenever epistaxis occurs, but it usually is impossible to manage against their underlying causes as a specific therapy. The authors considered the breakdown or weakness of vascular integrity of nasal capillary vessel wall as an important factor of recurrent epistaxis, and vitamin C, which has an important role for the synthesis of collagen fiber, could influence to the vascular integrity of nasal capillary vessels. To elucidate the relation between recurrent epistaxis and the status of vitamin C in the tissue of the patients, the authors performed urinary vitamin C loading test measuring urinary excretion of vitamin C with high-performance liquid chromatography by Sirota et al in 19 cases of control group and 32 cases of patients with recurrent epistaxis, whose underlying diseases were not identified. And also the authors administered 1.0 gm/day of vitamin C orally for the treatment of recurrent epistaxis and follow-up was done over 1 year from the beginning of treatment to evaluate the treatment response. The results were as follows: 1) The hemoglobin level was significantly decreased in patient group compared with that of control group (12.4+/-0.8 vs 9.0+/-3.2 gm/dl). 2) The results of urine loading test of vitamin C, expressed as the percent excreted ratio, revealed significantly decreased in the patient group compared to that of the control group (9.1+/-6.1% vs 13.6+/-7.9%). 3) After treatment with 1.0 gm/day of vitamin C orally, follow-up was possible in 23 cases of total 32 patients. Of the 23 patients, "excellent" therapeutic response were in 16 cases (69.6%), "good" response in 5 cases (21.7%), and "no response" only in 2 cases (8.7%). The overall treatment response were in 21 cases (91.3%). In conclusion, it seems that majority of the patients with idiopathic recurrent epistaxis in the deficient state tissue vitamin C so that administration of vitamin C will be one of the effective therapy.

Secondary ischemic necrosis of femoral head due to loss of blood supply following to femoral neck fracture is well known. The regional distribution of bone.seeking radiopharmaceuricals in the skeleton can depend on a number of facto rs, but bone blood flow is a major physiological determinant of regional skeletal uptake of Tc-99m polyphosphate and bone imaging may thus be used for the evaluation of vascularity of the femoral head. The authors made a comparative study of scintigraphic findings and operative findings of 28 cases of femoral neck fracture treated at Kyung Hee University Hospital from April ′80 to May ′84. The results were as follows: 1. In 16 cases of proven avscular necrosis of femoral head, scintigraphy showed absent or decreased activity in 14 cases (87.5%), while radiography showed increased density in 10 cases (62.5%). 2. In 12 cases of proven vital femoral head, scintigraphy showed increased activity in 9 cases (75%) and radiography showed decreased density in 9 cases (75%). 3. 99mTc-MDP scintigraphy was an excellent and useful method for assessing bone vitality of femoral head.

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.

Since the pattern of the frequency distribution of a parasite within a host showed an overdispersed pattern, various statistical models such as Poisson, negative binomial and lognormal distributions have been applied on the population dynamics in host-parasite relations. The observed data on the number of metacercariae of Clonorchis sinensis in a suitable intermediate host, Pseudorasbora parva which were collected from an endemic area, Juk-Rim River, Kim-Hae Goon, South Kyong-Sang Do were applied on the statistical models. The results obtained are as follows: By the calculation of the raw data, 258(94.9 percent) out of 272 fish showed positive to the metacercarial infection of C. sinensis. The mean number of metacercaria in a fish was 335.1. The standard deviation was 250.6 and the mode was observed between 250 and 299. The frequency distribution pattern of metacercariae of C. sinensis within the fish host in surveyed area was fitted to the lognormal distribution (0.05 parasitology-helminth-trematoda ; Clonorchis sinensis ; metacercaria ; Pseudorasbora parva ; frequency distribution ; host
