An appreciation of daily and annual changes of ultraviolet radiation is important in order to optimize the conditions for climatic therapy of skin diseases or in order to minimize the harmful effects of the sun. Ultraviolet A(355nm) and ultrviolet B(290nm) doses were measured at Kongju from April to September, 1985, on two different weather conditions-clear and relatively clear. The followings were the summary of the findings. 1. On clear weather, UVA dose was peak at noon of the day and in June of the year. 2. On relatively clear weather, UVA dose was peak at 2 p.m. of the day and in July of the year. 3. UVB dose was peak at noon of July regardless of weather conditions. 4. In relatively clear weather the UVA and UVB doses decreased from those of clear weather by 29%, and 36% respectively. 5, The relative difference between the doses of UVA and UVB depended on the degree of solar zenith angle. The greater the solar zenith angle, the greater the difference. 6. In order to treat a patient with solar UVA radiation, therefore, it is suggested to have the patient expose himself to the sun around 10 a, m. and 3 p.m. to minimize the harmful effects of solar UVB. However, when one wants to treat with solar UVB radiation, it would be better to expose to the sun around noon.

OBJECTIVE: We investigated the effect of preeclampsia, birth weight, fetal sex, maternal body mass index(BMI) on cord blood leptin concentrations. This study is to test whether leptin would be increased in preeclampsia and to test cord leptin concentrations for correlation with maternal leptin concentrations. METHOD: Maternal blood samples were obtained from 56 normal pregnancies and 24 preeclampsia women prior to delivery. Umbilical cord blood were obtained from the all cases studied immediately after delivery. The total leptin levels were determined by radioimmunoassay. RESULTS: Mean maternal leptin level was 16.4+/-6.4ng/ml in normal pregnancy and was 19.4+/-7.9 ng/ml in preeclampsia. Mean cord leptin level was 5.4+/- 3.4ng/ml in normal pregnancy and 4.6+/-3.2ng/ml in preecalmpsia. Mean cord blood leptin level in female fetus was 6.6+/-3.7ng/ml and 4.8+/-2.8ng/ml in male fetus. CONCLUSION: This study shows that there are correlation with leptin level and fetal birth weight, body mass index, and fetal gender. Furthermore, physiologic role and mechanism of leptin of maternal serum and umbilical cord would be studied.

An analytical observation was carried out on clinical symptoms, physical findings, etiology, precipitating factors, pulse rate, and blood pressure manifested by 115 patients admitted to the Kyung hee university Hospital under the diagnosis of congestive heart failure for a period of October 1971 to September 1974. The results were as follows: 1. The disease affected female 1.4 times more frequently than male and occured most frequently in the 6th decade (26.1%), and its incidence decreased in the 7th decade (22.6%). 2. The important causes of congestive heart failure were hypertensive heart disease (39.7%), rheumatic heart disease (26.1%), cor pulmonale (13.9%), atherosclerotic heart disease (6.1%), postpartum heart failure (6.1%) and pericardial disease (3.5%). The unknown etiology was 3.5% of all cases. 3. The most common precipitatiog factors of the 106 patients of congestive heart failure were infections (59.5%), especially in the upper respiratory tract infection (37.8%). The physical exertion, pregnancy and labor, psychic stress, angina, myocardial infarction, and discontinuation of Tapazol and digitalis were followed. 4. The most common symptoms and signs were the dyspnea (93%), and the next common were pulmonary rales (65.2%), hepatomegaly (59.1%), distention of cervical vein (55.7%), pitting edema (44.3%) and cardiac murmur (38.3%) on admission. 5. The increased pulse rate over 101/min. was about 38.3%, but less than 60/min. was found in 4.3% only. 6. The electrocardiographic findings were abnormal except one case out of 107 cases. The left ventricular hypertrophy (48.1%), atrial fibrillation (24.5%), and bundle branch block (21.7%) were frequently observed. 7. The range of systolic blood pressure measured in 43 patients who had been suffered from hypertensive heart disease were disclosed that 221-240 mmHg (23.3%), 161-180mmHg (20.9%), and 181-200mmHg (20.9%) in order.

Small cell carcinoma of the ovary is rare malignancy occurring in women under 40 years of age(average, 23 years), which is associated with hypercalcemia in two thirds of cases. Its histogenesis is uncertain, but the possibilities of common epithelial, neuroendocrine, sex cord stromal and germ cell origin are suggested. All reported cases were proved to have rapid fatal course despite various therapy and 5 years suvival rate was only 10%. We report one case of a 20-year old woman with primary small cell carcinoma of the left ovary. The ovary was markedly enlarged and completely replaced by a mass, measuring 21x16x8 cm. Microscopic examination revealed dimorphic population of small and large malignant cell producing immature follicle-like structure which is characteristic of small cell carcinoma of the ovary. These pathological findings were similar to those of granulosa cell tumor, which is required to make differential diagnosis from small cell carcinoma. Immunohistochemical stains for cytokeratin and vimentin were positive, but those for S-100 protein and NSE were negative. One month after the initial operation, the tumor has recurred and the second and the second palliative operation followed by 3 cycles of chemotherapy was done. The patient showed disseminated metastasis at present time.

BACKGROUND: Acutely induced hypoxia causes an increase in the mean arterial pressure, cardiac output and oxygen consumption. However, comparisons of hemodynamic changes and oxygen consumption between subjects with and without anesthesia are rare. The purpose of this study was to examine and compare the hemodynamic changes and oxygen availability after acute apnea between the dogs with and without anesthesia. METHODS: Apnea was induced to 19 healthy mongrel dogs. Group 1 (N=10) constituted dogs with anesthesia and group 2 (N=9) constituted dogs without anesthesia. Hemodynamic data and oxygen levels were rapidly measured with 1 minute intervals. RESULTS: The survival time of group 1 was longer than that of group 2. The mean arterial pressure increased in group 1. Although the cardiac outputs in both groups increased at the same time course in early phase of apnea, the preload values increased more rapidly in group 1. Systemic vascular resistance decreased at 2 and 3 minutes of apnea in group 1 but not in group 2. The oxygen extraction ratio increased significantly at 4 and 5 minutes of apnea in group 2. CONCLUSION: In this study the dogs with anesthesia had a prolonged survival time compared to the dogs without anesthesia. Most hemodynamic values did not differ significantly between the two groups, except for an increased mean arterial pressure and decreased systemic vascular resistance in the dogs with anesthesia. It was suggested that the cause of early death in the dogs without anesthesia was decreased oxygen delivery.

The use of hyperventilation technique to reduce intracranial pressure for surgical intervention of cerebral aneurysm has been well documented and most common in general practice. The decrease of blood flow with hyperventilation may aggravate pre-existing ischemic region. On this occasion it was suggested that cerebral intracellular metabolic acidosis may be accentuated so that its metabolic status could be measured from the analysis of cerebrospinal fluid gases. Hyperventilation can cause an increase in PH of cerebrospinal fluid due to the decrease of PCO but if hyperventilation is induced chronically, an elevated PH returns gradually to its previous normal value by loss of HCO, from the cerebrospinal fluid. Anesthesia was maintained with hyperventilation throughout the cerebral aneurysm surgery then cerebrospinal fluid and arterial blood gases were measured at regular intervals. PH in cerebrospinal fluid at 1 hour after hyperventilation revealed severe metabolic acidosis and arterial blood gases showed respiratory alkalosis. At 6 hours after hyperventilation the PH in cerebrospinal fluid in-creased markedly but the changes of HCO2were not significant from its control value and accord-ingly metabolic acidosis in cerebrospinal fluid was improved. It was suggested that compensatory mechanism for PH of cerebrospinal fluid to return to its low value by decreasing HCO2was shown. If such mechaniwm does not exist cerebrospinal fluid HCO2must he increased theoretically.

Background: Triiodothyronine(T3) is a hormone secreted from thyroid gland which exerts a stimulating effect on metabolism. The disorder of thyroid system brings about several serious diseases like hypothymidism or hyperthyroidism. Therefore, the determination of T in blood is very important on monitoring thyroid function. Methods: Rabbit anti-T3 antibody was generated by immunization of T-BSA as an immunogen and purified hom antisera using Affi-gel protein A kit. The titer and specificity of purified antibody were characterized. To detect T3, competitive ELISA was performed using anti-T3 antibody and T3-HRP conjugate which was synthesized by glutaraldehyde method. The sensitivity and precision assay wer~e deterrnined and compared with that of RIA. Results: The titer of purified anti-T3 antibody was about 1:100 and the optimal dilution of T3- HRP conjugate was 1:1000. When the standard curve was constructed by ELISA, its sensitivity was about 0.5ng/ml. The eoefficient variations of intra- and inter-assay were 4.9~9.3% and 7.5~13.8%, respectively. The results obtained by ELISA and RIA correlated well with each other(n =50, r= 0.97), The linear regression equation was y= 1.09*0.08(P<0.01). Conclusion: We successfully developed a method for the measurement of T3 on ELISA which was based on competitive reaction between antigen(T3) and enzyme labeled antigen(T3-HRP). These results demonstrated that competitive ELISA is a convenient, fast, reproducible and aecurate method for the determinstion of T in serum and can be used as practical alternative to RIA.

OBJECTIVES: Anxiety and depression are known to be associated with hypertension, and blood pressure can vary spontaneously throughout the day. The aim of this study was to evaluate anxiety, depression and 24-hour ambulatory blood pressure (24-h ambulatory BP) in employees at their worksite. METHODS: A total of 107 volunteers among 136 employees at a hotel in Gyeongju, Korea were enrolled in this study between December 2009 and March 2010. The Beck Anxiety Inventory (BAI) and the Beck Depression Inventory (BDI) were used to assess anxiety and depression, respectively. Blood pressure was measured using a 24-h ambulatory BP monitoring system. RESULTS: No significant differences in either BAI or BDI scores were found when hypertensive individuals were compared to normotensive individuals. The frequency of diastolic non-dipper was significantly higher in individuals with depressive symptoms compared to those without (p<0.05). Depression was significantly associated with diastolic non-dipper (OR: 6.85, 95% CI: 1.50-30.01). CONCLUSIONS: The results of this study indicate that depression should be considered when deciding upon blood pressure control regimens, and appropriate additive psychotherapy may be beneficial in the treatment of hypertensive patients.
