BACKGROUND: Almost all STD(sexually tranamitted diseases) have been increasing worldwide since the 1960s. In Korea, the occurrence of STD from recent trends of sexual openness and development in the pleasure-seeking industry is becoming a social issue. However, epidemiological studies and reports concerning the incidence of STD are lacking in Korea, especially in the sexually aetive young age group. OBJECTIVE: We evaluated the incidence of YTD and sexual behavior of recruits in a Korean arrny training center to contribute to the management of STD in Korea. METHODS: We studied 1304 recruits in a Korean army training center by questionnaire, physical examination and laboratory data. The subjects were divided into 3 groups: group 1(1072 persons), those who visited the hospital for evaluation of STD; group 2(641 persons), a control group for coitus rate; and group 3(1304 persons; group 1 plus 232 persons out of group 2), those who had coital experiences. RESULTS: 1. The incidence of STD in group 1 was 65.7%(704/1072) and that of the total number of recruits was 0.43%(704/164,134). 2. Among the 704 cases of STD, the most frequently observed STD was non-gonococcal urethritis, 292 cases(41.5%) and the second was gonorrhea, 236 cases(33.5%). The others were, 68 cases(9.7%) of pediculosis pubis, 41 cases(5.8%) of condyloma acuminatum, 29 cases(4.1%) of syphilis, 20 cases(2.8%) of combined STD, 14 cases(2%) of herpes progenitalis, 2 cases(0.28%) of molluscum cohtagiosum and 2 cases(0.28%) of chancroid. 3. The coitus rate in group 2 was 36.2%(232/641). 4. The incidence of previous STD in group 3 was 20.9%(273/1304). 5. The mn;t common form of STD which the patients experienced previously was urethritis(82.8%) and the others were pediculosis pubis(7.3%), syphilis(3.3%), condylcena acuminahun and herpes progenitalis. 6. The group with more sexual partners tended to have a lower educational level. 7. The experience rate of drug abuse was higher in the group with more sexual partners. 8. The experience rate of oral and anal sex was higher in the group with experiences of clrug abuse than in the ather one. CONCLUSION: In this study, urethritis was the most common form of STD(75% of all STD) and non-gonococcal urethritis showed a greater incidence than gonorrhea. The incidence of STD is thought to be closely related to the factors associated with social or behavioral science, such as the number of sexual partners, grade of education, drug abuse, experience of oral and anal sex. To accomplish more effective management of STD, therefore, the improvement of current social problems involving sexual openness, the pleasure-seeking industry and drug abuse should be achieved.

The authors report their experiences of direct intracranial operation on 2 cases of ruptured giant middle cerebral artery aneurysm which have similar diameter size (over 2.5cm) and location (middle cerebral artery bifurcation area). On had showed subarachnoid hemorrhage at the right sylvian fissure and another had showed was operated 25 days after ictus because of generalized seizure attack and vasospasm on cerebral angiography, the latter was operated within 18 hours after ictus due to semicomatose mental state and intracerebral hematoma on the right temporal lobe. We have utilized on giant aneurysmal surgery with multiple tactics such as transient hypotension, temporary clipping, multiple clipping, puncture or incision of the aneurysmal body and removing of hematoma.

Left ventricular false tendon, also called moderator bands, anomalous cords, accessory bands or false chordae tendinae, has been known as simple anatomical without clinical importance. But the possible relationship with Still's type murmur and ventricular arrhythmia were reported recently. The incidence of false tendon was known as 0.5-6.1% variably. In Korea, there are no reports about left ventricular false tendon till now. The authors examined 2,052 patients' echocaediograms and clinical manifestations retrospectively to find the incidence and potent clinical significance of false tendons. The incidence in present study was 1.02% and there was no specific relationship between false tendon and cardiovascular diseases. The authors observed Still's type musical murmur in 5 patients out of 21 and ventricular premature beats in 2 patients out of 10 without other cardiovascular diseases. One of them showed nonsustained ventricular tachycaedia during Holter ECG monitoring. The most frequent echocardiographic site of attachment was from basal inter-ventricular septum to lelft ventricular free wall and false tendon attached to papillary muscle was least frequently observed.

Identification of patients with combined valvular prolapse has important clinical imlications, because such patients appear to be early surgical candidates. Detection of combined valvular prolapse became more feasible with development of 2-dimentional echocardiography and the incidence of combained mitral and valve prolapse is reported to be variable from 3% to 24%. The authors found a case of combined mitral and aortic valve prolapse detected by 2-dimensional echocardiography. This 30-years-old male patient who admitted because of peptic ulcer bleeding revealed a prolapse of anterior mitral leaflet with regurgitation and also a prolapse of the right coronary cusp into the left ventricular outflow tract but without evidence of aortic regurgutation by Doppler echocardiogram. he discharged without surgical intervention and needs further observation.

BACKGROUND: Cadmium, an environmental pollutant, has implicated in the pathogenesis of cardiovascular diseases. Biochemical and pathophysiological changes characterized by arterial hypertension, accelerated cholesterol plaque formation on arterial walls, cardiac conduction abnormalities, and reduction in myocardial contractility have been reported in experimental animals chronically exposed to low concentration of cadmium. This study was undertaken to evaluate the ultrastructural changes of the cardiac muscle in rats exposed to cadmium chloride and to ascertain whether these changes are modified after discontinuation of cadmium feeding. METHOD: Wistar strain rats(body weight 200~250gram) were injected intraperitoneally once weekly with 3.75mg/kg of cadmium chloride for 10 weeks and were sacrificed at 1 day, 1 week and 2 weeks after discontinuation of cadmium administration. RESULT: Ultrastructure if rat cardiac muscle fibers after cadmium administration revealed that mitochondria were increased in number and their cristae were severely damaged. Cardiac myofibrils and myofilaments were reduced. Z-disc were partly dislocated and A-bands and I-bands were not clearly defined. Irregularly arranged intercalated disc and disrupted sarcolemma were also found. These structural alterations resulting from cadmium feeding were partly reduced after removal of cadmium exposure for 2 weeks. These structural alterations resulting from cadmium feeding were partly reduced after removal of cadmium exposure for 2 weeks. CONCLUSIONS: It is suggested that exposure to cadmium chloride was associated with cardiac ultrastructural changes which might be responsible for physiologic abnormalities and these alterations may be partly reversible after discontinuation of cadmium administration.

BACKGROUND: One of the unique feature of ambulatory blood pressure monitoring is its ability to describe the variations of BP throughout the day and night. Left ventricular hypertrophy and other measures of target organ damage in hypertension are more closely related to the average 24-h BP than to clinic BP. In addition to the mean levels of BP, the characteristics of the 24-h BP profile might be a further determinant of organ in essential hypertension. METHODS: Data were obtrained from 105 patients with essential hypertension and 44 normal subjects. Echocardiography and 24 hour ambulatory blood pressure monitoring were performed in all subjects. At first, relative wall thickness(RWT) and left ventrcular mass index were calculated from normal subject and normal values(RWT<0.44, LV mass index,120gm/m2) were applied to hypertensive patients which were classified to dipper and non-dipper according to the result of ambulatory monitoring. RESULTS: 1) There were 49 dippers and 56 non-dipper in hypertensive patients subjects. 2) Among the dippers, left ventricular mass index and relative wall thickness were normal in 51%, whereas 8.2% had increased relative wall thickness with normal ventricular mass(concentric remodeling), 32.7% had increased mass with normal relative wall thickness(eccentric hypertrophy) and 8.2% had typical hypertensive concentric hypertrophy. 3) Among the non-dippers, left ventriculat mass index and relative wall thicksness were normal in 40%, whereas 41.8% had eccentric hypertophy, 16.4% had concentric hypertrophy, only 1.8% had concentric remodeling. 4) The incidence of concentric hypertophy was significantly increased in non-dipper subjects(15.2%) than dippers(8.2%), especially in non-dipper female patients. 5) The incidence of concentric remodeling was increased in dipper(8.2%), especially in dipper female patients. 6) There were no difference between left ventricular geometies in duration of hypertension, ejecton fracton, fractional shortening, and cardiac index. 7) There were no difference between dipper and non-dipper subjects in total peripheral resistance except dipper female patients(1,484+/-535 dynes.s.cm5). CONCLUSION: Patterns of left ventricular hypertophy and geometric remodeling in essential hypertension may not be influenced by the duration of hypertension, but by gender, blood pressure level, diurnal rhythm and total peripheral resistance.

The clinical trial was carried out with Bunazosin in 31 patients with essential hypertension. The results were as follows : 1) Before and after 1, 2, 4, 6, and 8 weeks of medications, the overall average systolic and distolic blood pressure were 166.5+/-21.8/105.7+/-10.6, 152.7+/-17.2/99.8+/-11.1, 149.5+/-18.1/98.4+/-11.7, 148.5+/-16.9/97.3+/-11.3, 148.5+/-16.7/95.6+/-10.9 and 144.0+/-14.9/94.2+/-11.1mmHg. As a result, blood pressure significantly fell within 1week of medication, and marked and moderate degree of hypetensive effect was observed within 8weeks og medication in 45% of all cases. 2) Before and after 1, 2, 4, 6, and 8weeks of medication, the overall average heart rates were 79.7+/-10.1, 78.3+/-9.1, 79.4+/-7.4, 80.8+/-8.3, 79.2+/-8.9 and 80.1+/-8.3 beats/minute. There were no significant change in heart rates before and after medication. 3) There were no significant changes in values of complete blood counts, GOT, GDT, blood urea nitrogen, serum creatinine and total cholesterol before and after medication. On the basis of these results, we observed that Bunazosin was effective hypertensive drug.

The authors report series of 360 cases of transthoracic fine-needle aspiration cytology (TFNA) from Oct. 1982, through Aug. 1986 at the Seoul National University Hospital. A diagnosis of neoplastic lesion was established in 50.3% of the cases. A non-neop- lastic diagnosis was made in 38.5%, nondiagnostic one in 6.5% and inadequate one in 4.7% of the total. Statistical findings on cytological diagnoses were as follows. Specificity was 100%: sensitivity, 92%; predictive value for positive, 1.0: predictive value for negative, 0.9; concordance rate, 84.2%: diagnostic accuracy in non-neoplastic lesion, 65.4%, and typing accuracy in malignant tumor, 0.77.
