The level of copayment increased in order to stabilize the financial condition of the health insurance on 1986. An important question regarding the policy was whether the increase in the level of copayments reduced the utilization of medical services in the poor selectively. In spite of the importance of the research question, no study has been reported. This study was designed to find out changes in nuniU rs of physician visits, to explain charac teristics influencing the difference of utilization before and after the program. Finally the interaction effect between the program and the level of income was examined for the abover question. A total of 10,421 persons from eight institutions was selected as the study sample. Research findings are as follows. 1. The number of physician visits decreased by ten percent as a result of increasing the level of copayment. 2. The decrease was remarkable in some groups such as children, rural area and large family. 3. The most important factor which explained the difference was the number of physician visits before the introduction of the new program.. The more numbers of physian visits during the last year were, the more numbers of physian visits decreased after the program. 4. The interaction term between the program and the level of income was statistically significant in the multiple regression model which explained physician visits and its coefficient was negative. It means that an increase in copayment did not reduced the number of physician visits in the poor, selectively. 5. It can be concluded that imposing adequate copayment reduces the use of medical services as well as medical costs without serious damage in access especially for the poor pule.

Thyroid Dysgenesis*

Two cases of vitiligo-type hypomelanosis followed by the local application of Benoquin ointment for the treatment for the treatment of melasma are reported. These two cases of hypomelanosis are unwanted and unintended side effects probably caused by the application of monobenzyl ethers of hydrcquinone (monobenzone). Monobenzone blocks the enzyme tyrosinase and thereby prevents the conversion of tyrosine to dihydroxyphenylanine, a precursor of melanin, and since this does not destroy melanocyte or facilitate the loss of melanin. The skin contact with the material will not occur, repigmentation will slow but eventuaIly complete.

BACKGROUND: The acute effect, of ethanol (EOH) include lowered blood pressure through peripheral vasodilation and decreased circulating blood volume. This study was aimed at examing the effects of EOH on the hemodynamic response to up and down head tilts. METHODS: Ten 21 to 23 year old male adults served as subjects. Each subject participated in both control and EOH experiments. In the EOH experiment, 3 mls of 25% EOH per liter of total body water was administered orally, 35 min were allowed for the blood EOH level to reach maximum before the tilt protocol was initiated. The tilt protocol consisted of 5 stages, each stage was 3-min in duration : supine (0 degrees)-head down tilt (HDT, 15 degrees)-supine (0 degrees)-head up tilt (HUT, 25 degrees)-supine (0 degrees). Hemodynamic parameters were measured with an impedance cardiograph (NCCOM3-R7, BoMed) with two electrodes placed around the neck and two around the thorax. Blood pressure (BP) was measured with an automatic sphygmomanometer (DATEX). Data was collected during every second half-minute throughout the duration of the protocol. RESULTS: In the control, HDT produced an increase in the end-diastolic index (EDI), the stroke index (SI), the cardiac index (CI), and the peak flow index (PFI) ; there were no significant changes in heart rate (HR), the systemic vascular resistance index (SVRI), and BP. In contrast, HUT resulted in a decrease in EDI, SI, EF, CI, and PFI and an increase in HR, SVRI, and BP ; the latter changes sugges a sympathetic overactivation. In the EOH experiment, the basal EDI, SI, and systolic BP were lower and HR was higher than in control. HDT and HUT caused similar changes as in control experiments. CONCLUSIONS: There results indicate that EOH cause volume depletion to result in reduced central blood volume and compensatory tachycardia. These EOH-induced changes were not altered by 15 degreeshead-down and 25 degreeshead-up tilts.

One-hundred-eleven herpes simplex viruses(HSV) were isolated from l09 patients who had visited the Department of Dermatology, Ophthalmology, and Gynecology of Hanyang University Hospital from 1986 through 1988, for suspected HSV lesions. The cultured viruses were classified into HSV-1 and HSV-2 by using direct and indirect immunofluorescent staining with monoclonal antibodies against HSV. In this study, HSV type 1 were predominantly involved in the HSV lesions above the waist of the patients(83.6%), and the infections caused by HSV type 2(I3.1 %) and bath HSV types(3.3%) were also noted. In contrast, the main organism of the HSV lesions below the waist were HSV-2(80.0%), and HSV-1(16.0% ) and both types(4.0%) were also involved in. The result suggested that the number of patients with HSV 1 genital herpes and/or with non-genital herpes by HSV-2 were apparently increasing. In conclusion, it is conceivable that the classification of HSV isolates might be useful for determining prognosis as well as performing epidemiologic studies of HSV infections.
