BACKGROUND: In order to investigate the efficacy and safety of cilazapril, a recently developed angiotensin converting enzyme inhibitor, a clinical study was performed in the patients with mild to moderate essential hypertension. METHODS: The study subject consisted of 31 patients with diastolic blood pressure of 95mmHg~115mmHg (mean age : 56.0+/-8.1 years, 16 males and 15 females). Cilazapril was administered orally in a daily dose of 2.5mg~5.0mg Q.D. for 8 weeks. During cilazapril medication, anti-hypertensive efficacy, side effects and laboratory changes were monitored. RESULTS: Cilazapril decreased blood pressure from baseline value of 162.2+/-4.7/98.4+/-2.8mmHg to 144.6+/-10.0/89.7+/-5.7mmHg after 4weeks of medication (p<0.05) and 138.2+/-4.5/87.8+/-4.0mmHg after 8 weeks of medication (p<0.05). Heart rate change was not significant (72.3+/-4.7/min vs 71.7+/-3.6/min). Body weight change was not significant (66.6+/-9.8 Kg vs 66.8+/-9.9 Kg). There were no significant change in blood chemistry and hematologic examination except mild elevation of alanine transaminase and serum creatinine values but these date were within normal ranges. The side effects were dry cough (4 case, 12.9%), headache (2 case, 6.4%), indigestion (1 case, 3.2%) and dry mouth (1 case, 3.2%). One patient dropped out due to severe dry cough but others were mostly mild in nature. CONCLUSIONS: Cliazapril 2.5mg~5.0mg once daily regimen was effective and well tolerated in patients with mild to moderate essential hypertension.

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.

This study was performed to evaluate the diagnostic value of colposcopy by comparing colposcopic findings with cytology, histology of colposcopically directed biopsy and final biopsy result on hysterectomy. From January 1, 1988 to August 31, 1996, the colposcopic examinations was undertaken in 1200 patients, excluding grossly visible carcinoma of the cervix. The result were as follows : 1. Colposcopic examinations were satisfactory in 95.4% and unsatisfactory in 4.58%. 2. The accuracy rate of cytologic diagnosis was 73.1% and colposcopic impression was 93.1%. 3. The false negative rate of colposcopic impression was 2.6%, much less than 24,7% of cytologic examination. 4. The cytologic accuracy rate in cervicitis was higher than that of colposcopic impression but the accuracy rate of colposcopic impression in diagnosis of cervical intraepithelial neoplasia was higher than that of cytology. 5. Among 97 cases in which colposcopically directed biopsy were performed, more advanced lesion were disclosed in 12 cases(12.4%).

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.

In single atrial and ventricular cells isolated from the guinea-pig and the rabbit heart, action potentials and membrane currents were recorded by using the whole cell voltage clamp technique. In rabbit atrial cells the repolarization showed two distinctive phases, referred as the early and late phases(early and late plateau phase), but in guinea-pig atrial cells there was a maintained plateau and less distinctive two phases of repolartization. Increasing intracellular sodium or reducing external sodium by replacement with lithium suppressed the late phase of the action potential in rabbit atrial cells and shortened the plateau of action potential in rabbit ventricle and guinea-pig atrial cells. Reducing external sodium decreased Ca-current and late inward current in voltage clamp. Ouabain in the concentration of 10(-5)M shortened the duration of action potential and shifted the holding current level to outward direction, decreased Ca-current and moved late inward current to outward direction. Ryanodine 10(-6)M which is known to be an inhibitor of Ca-release in the intracellular store, suppressed the late phase of action potential in rabbit atrial cells and shortened the plateau of action potential in rabbit ventricular cells. Ryanodine also decreased Ca-current and shifted late inward current to outward direction. It is concluded that an inward current activated by intracellular calcium contributes to the late Phase of the action potential in rabbit atrial cells and to the late plateau in rabbit ventricular cells and in guinea-pig atrial cells. It may be carried by the Na-Ca exchange precess and/or by calcium-activated non-specific channels but preferably Na-Ca exchange machanism.

Left ventricular hypertrophy is a compensatory response to hemodynamic overload secondary to an increased systemic resistance. This increase, however, is not the only cause of hypertrophy, and there are other factors which can have a significant effect on its incidence. To determine whether chronic antihypertensive therapy by enalapril modifies the cellular and subcellular changes of left ventricular hypertrophy observed in spontaneously hypertensive rats(SHR), 20-weeks-old SHR were treated for 22 weeks with enalapril(2mg/kg) and compared with normotensive Wister-Kyoto rats and not-treated SHR. Systolic blood pressure in enalapril-treated SHR was significantly lowered after 22 weeks compared with that of untreated control SHR group. Myocytes were reduced in size and fibrination seen in cardiac muscle fibers of control SHR was decreased in treated SHR group. Myofibrils appeared to be irregular in shape and myofilaments are decreased in control SHR but in enalapril-treated SHR the diameter and length of the myofilament became turned to regular forms. These results suggest that, enalapril, angiotensin converting enzyme inhibitor, may regress hypertrophy and some subcellular changes may be modified by enalapril.
