BACKGROUND: Chicken pox and herpes zoster are caused by the varicella-zoster virus(VZV). To investigate the epiderniologial relationship between clinical isolates of VZV, it is essential to distinguish different isolate. OBJECTIVE: This study was conducted to classify the VZV strains according to R5 tandem direct reiterations(TDR) copy numbers and Pst I endonuclease cleavage site mutation, and to analyze the distribution pattern of VZV strains isolated in Korea. METHODS: Strains of VZV were isolated from 61 patients with herpes zoster who had not been immunized with a live vaccine of VZV. Copy numbers of R5 TDR which was located in variable region IV were measured by PCR. The presence of a Pst I cleavage site in a middle portion of the long unique region of VZV genome was analyzed by PCR thereafter restriction enzyme digestion(PCR-RFLP). RESULTS: VZV strains isolated in Korea contained one to three copy numbers of R5 TDR. Of 61 isolates, 43(70%) comtained 2 copies of R5 TDR, while 11(18%) isolates contained only one copy and 7(12%) isolat s contained 3 copies. About 16% of the strains examined did not have a PstI cleavage site, although the majority of strains retained this site. VZV strains could be classified into 6 strains on the basis of the copy number of R5 TDR and PstI cleavage site, in which the strain with 2 copies of R5 TDR and PstI cleavage site positive was the most frequent type (36 out of 61 isolates) in Korea. Four batches of live attenuated vaccine(Biken) that is now used in Korea showed 2 copy numbers of R5 TDR and PstI site negative. CONCLUSION: The copy number of R5 TDR and the presence of PstI cleavage site seems to be a reliable marker for dicrimination of VZV strains in Korea. This discrimination can be used to study the molecular epiclemiology of VZV and as a criterion for identification of vaccine-related isolates.

The multistage maximal exercise test was performed to 135 cases with various heart disease and 207 control group between jan. 1980 and Dec. 1980 in KoreaGeneral Hospital. The change of heart rate, blood pressure and ST segment in various heart disease were compared with those in control group. The results were followings; 1. There were 130 male and 77 female of cases with control group, whose mean age were 50 years old. 2. General check up was the most common underlying disease of control group(67 patients) and the others were gastritis (28), neurosis (24), diabets mellitus (17), hepatitis (4) and peptic ulcer (4) frequency. 3. Change of heart rate, blood pressure and ST segment in control group during GXT were 89~154, 119/80~157/88 mmHg and 0.6~2 mm. 4. There were 81 male and 51 female of cases with various heart disease group, whose mean age were 50 years old. 5. Atherosclerotic heart disease was the most common underlying disease of various heart disease group (49 patients) and the others were hypertension (34), hypertensive cardiovascular disease (22), labile hypertension (14), angina (7), arrythmia (6) and others (3) in frequency. 6. Change of heart rate, blood pressure and ST segment in various heart disease group during GXT were 85~148, 140/93~178/102 mmHg and -0.7~1.3mm. ST segment in atherosclerotic heart disease, hypertension, hypertensive cardiovascular disease, valvular heart disease and myocardial infarction were significantly depressed(p<0.05) compared with ST segment in control group.

PURPOSE: To clarify the chracteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. MATERIALS AND METHODS: We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. RESULTS: The tumors included 33 lipomas, 11 hemangiomas. 11 lymphangiomas, 7 neurilemmomas, 4 epidermold cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The SOhographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxoma), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and chacteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymphangioma. Neurilemmoma showed Iobulated, oval to round, relatively hypoechoic mass with or without internal cystic portion. CONCLUSION: Sonographic evaluation of benign soft tissue tumros is useful in demonstrating the location, size, extent, and internal characteristics of the mass. A relatively confident diagnosis can be made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging.

We report the clinical features in one patients with episodic positional vertigo and apogeotropic direction changing horizontal positional nystagmus that does not fatigue, beating to the right with the head turned to the left and beating to the left with the head turned to the right. This syndrome probably represents a horizontal semicircular canal variant of benign positional vertigo. Free-floating debris and Cupula attached debris in one horizontal semicircular canal may explain many of the clinical and oculographic findings.

Pulmonic autograft replacement of the aortic valve (Ross procedure) has been to have potential for growth in children, no complication of antiocagulation, and enhanced durability. Therefore, Ross operation is indicated in the young, in patients with an active life style, and when anticoagulation is contraindicated. However, late autograft valve has occurrd more frequently in patients with significant size discrepancy between the pulmonay valve annulus and the aortic valve annulus. In order to resolve this problem, we performed aortic annuloplasty with Duran ring for more accurate and strong reinforcement. We report a case using the Duran ring as a method of aortic annuloplasty during Ross procedure.

Discoid lateral meniscus is wider and thicker than normal lateral meniscus. The tear pattern and vulnerability to injury of discoid lateral meniscus may be different from that of normal shaped meniscus. Seven hundred and seventy one meniscal tears which were treated arthroscopically between the period of 1982 and 1995 were reviewed retrospectively. Of those cases, tear of normal shaped lateral menisci occupied 327 knees (42.4 %) and discoid lateral menisci 132 knees (17.1 %) representing the higher incidence of tear in normal shaped lateral meniscus. In normal shaped menisci there were no tear in the age of below 10 and there were 37 knees of teens. In discoid lateral menisci, there were 3 knees (2.3 %) of below 10 and 42 knees of teens (31.8 %) that represent higher incidence of younger age group (P<0.05). Tears without trauma history in 31 knees (9.5 %) of normal shaped lateral meniscus and in 70 knees (53.0 %) of discoid menisci represent vulnerability of the discoid lateral meniscus to tear without injury (P<0.05). Symptomatic menisci without tear were noted only in 16 knees (12.1 %) of the discoid lateral menisci. In normal shaped menisci, longitudinal tear within the substance was most common (119 knees, 36.4 %) whereas peripheral tear was most common (57 knees, 43.2 %) in the discoid lateral meniscus, Concealed horizontal tear (11 knees, 8.3 %) and Wrisberg type discoid lateral menisci (2 knees, 1.5 %) was noted only in the discoid lateral meniscus. In summary, discoid lateral meniscus revealed different tear pattern and vulnerability to injury and different age incidence from that of normal shaped lateral meniscus.
