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.

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.

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.

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.

BACKGROUND: This clinical trial was performed to evaluate the hemodynamic and side effects of enoximone, a newly developed phosphodiesterase inhibitor, in moderately severe congestive heart failure in Korean population and to base the development of long acting oral preparations in the future. METHODS: Principal admission criteria for this trial were a left ventricular ejection fraction of less than 45% by radionuclide ventriculography, NYHA functional class II or III and a documented congestive cardiomyopathy. Exclusion criteria were restrictive cardiomyopathy, valvular heart disease, multisystemic lillness and uncontrolled ventricular tachyarrhythmia. The hemodynamic measurements were made by using the thermodilution Swan-Ganz catheter and radial arterial canulation. Enoximone was administered(continuous infusion) for 24 hours after initial bolus. The hemodynamic parameters to be observed were blood pressure, heart rate, cardiac output, pulmonary capillary wedge pressure, systemic and pulmonary vascular resistance. The clinical reponse, hematology, blood chemistry, and Holter monitoring were checked before and after enoximone trial. RESULTS: The following results are obtained. 1) The included patients were 15 females, 24 males, total 39 patients and mean age of 55.3 years old(28-70 years old). 2) The causes of congestive cardiomyopathy were idiopathic 35(89.9%), hypertensive 3(7.7%), and alcoholic 1(2.6%). 3) The mean ejection fraction measured by radionuclide left ventriculography were 28. 6%. 4) THe cardiac output was significantly increased(50%), and pulmonary capillary wedge pressure(38%), systemic vascular resistance(34%), pulmonary vascular resistance(27%) were significantly decreased during enoximone infusion. 5) NYHA Functional Class was improved by 1 step with enoximone. 6) There were no significant changes in hematology, blood chemistry, and Holter monitoring with enoximone. CONCLUSION: From the above results, the short term intravenous enoximone was very effective in moderately severe congestive heart failure in congestive cardiomyopathy without major adverse effects in Korean.

The antihypertensive efficacy and safety of Dilevalol, compared with Nicardipine, were evaluated in mild to moderate hypertensive patients in a randomized crossover study. Following a 3 week placebo washout (phase I), the first crossover (phase II) was initiated with 63 patients randomized to dilevalol and 62 to nicardipine. The 6 weeks of treatment was initiated with 100mg of dilevalol once daily or 40mg of nicardipine (20mg B.I.D.). After 2 weeks, patients not achieving a sitting DBP to < or =90mmHg or a decrease of > or =10mmhg were uptitrated to 200mg Dilevalol once daily or 60mg Nicardipine twice daily. A second three week placebo washout (phase III) followed by a second 6 week active treatment phase (phase IV) during which patients were crossed over to the alternative therapy as during phase II if the sitting DBP again met the entrance criteria. 18 patients were only evaluable for the first washout and treatment period because of early discontinuation or protocol violations. They were included in the safety evaluation. phass II patients treated with Dilevalol (n=63) were mean age of 52.9 years, 49% male and 51% mild hypertensives (< or =105mmHg). Phase ??patients treated with Nicardipine (n=62) were mean age of 51.2 years 55% male and 66% mild hypertensives. Both Dilevalol and Nicardipine significantly and equivalently lowered blood pressure relative to baseline (71% versus 67% normalization). Dilevalol slightly but significantly lowered heart rate (-5 beat/min versus -1 beat/min). Dilevalol significantly increased HDL cholesterol (2.1mg/dl, 4.2%) and decreased total cholesterol (9.6mg/dl, 4.2%) while Nicardipine produced only a small but not significant reduction in total cholesterol (3.2mg/dl, 1.2%). The incidence of adverse effects were lower with Dilevalol than with Nicardipine and especially flushing and ankle edema occurred significantly more often with Nicardipine. in conclusion, dilevalol is equally effective but has a superior safety profile to nicardipine in the treatment of mild to moderate hypertension.
