OBJECTIVE: The aim of the study was to evaluate the corelation between an expression of lectins and survival of patients with squamous cell carcinoma of uterine cervix. METHODS: The cell surface carbohydrate profile of formalin-fixed paraffin embedded tissue section of squamous cell carcinoma of the uterine cervix was evaluated using ulex europaeus agglutinin(UEA-1), peanut agglutinin(PNA), dolichos biflorus agglutinin(DBA), soybean agglutinin(SBA) and lotus tetragonobus lectin(LTL) by the avidin-biotin complex method. Fifty-one cases of squamous cell carcinoma and 10 cases of normal squamous epithelium of the uterine cervix were selected from the file which were treated during Jan. 89 to 31 Dec. 1992 in Department of Obstetrics and Gynecology, Korea University Hospital. RESULTS: UEA-1 and LTL were negative in normal cervix while positive in 76.5%, 47.1% of squamous cell carcinoma respectively, and useful markers for differential diagnosis between normal and squamous cell carcinoma. SBA and LTL were useful for differential diagnosis of keratinizing and non-keratinizing squamous cell carcinoma. UEA-1 may play an important role in lymphovascular invasion of squamous cell carcinoma of the uterine cervix. CONCLUSIONS: There was no correlation among clinical staging, patient's survival and lectins binding in squamous cell carcinoma.

OBJECTIVE: Uterine cervical cancer is the most common malignant tumor in Korean women. Human papillomaviruses are associated in 85-90% of the cases. However, other cofactors are considered to be important in carcinogenesis. There is an evidence that the uterine cervix is the site of shedding of the Epstein-Barr viruses(EBV). Furthermore the virus has been detected in cervical intraepithelial neoplasia and invasive carcinoma of the uterine cervix. We studied to evaluate the role of EBV in cervical carcinogenesis. METHODS: Non-neoplastic cervices(12), carcinoma in situ(32), microinvasive squamous cell carcinomas(9), invasive squamous cell carcinomas(37) and adenocarcinomas and adenosquamous carcinomas(14) were studied for EBV infection. PCR and in situ PCR for EBNA-1 were done and subtyping was done using PCR for EBNA 3C. RESULTS: In non-neoplastic cervix, EBV was detected in 16.7% by PCR and found in normal epithelial cells and lymphocytes in in situ PCR. By PCR technique, EBV was detected in 65.6% of CIS, 66.3% and 51.4% of microinvasive and invasive squamous cell carcinomas, 57.1% of adenocarcinomas and adenosquamous carcinomas. EBV subtyping was done in EBV positive cases by PCR and all showed type 1. CONCLUSION: EBV was detected in higher frequency in cervical cancer than in non-neoplastic cervix. However the frequency was not correlated to the invasion depth and histologic types of cervical carcinomas. EBV was detected in tumor cells as well as normal epithelial cells and lymphocytes also. It was suggested that EBV may play a role in cervical cancers but the mechanism in carcinogenesis remains to be solved.

BACKGROUND: The safety of ergonovine provocation for coronary vasospasm (CVS) performed outside the catheterization laboratory has been questioned. We sought to address the issues of safety, feasibility and clinical impact of noninvasive diagnosis of CVS. METHOD AND RESULTS: We retrospectively analyzed the results of bedside ergonovine provocation testing with monitoring of left ventricular regional wall motion abnormalities (RWMAs) by 2-dimensional echocardiography (ergonovine echocardiography, Erg Echo). After confirmation of no significant fixed epicardial coronary artery disease, 1,504 Erg Echo were performed in 1,372 patients from July 1991 to December 1997. Erg Echo was prematurely terminated in 13 patients (0.9%) due to limiting side effects unrelated with myocardial ischemia. Among 1,491 completed tests, 32% (477) showed positive results with development of RWMAs in 467 tests (98%) or ST displacement in ECG in 10 tests (2%). During the test, transient arrhythmias developed in 1.7% (26/1491) including transient ventricular tachycardia (2) and atrioventricular block (4), which were promptly reversed with nitroglycerin. There were no procedure-related death or development of myocardial infarction. On the basis of angiographic criteria in 218 patients, who also underwent invasive spasm provocation test during coronary angiography, the sensitivity and specificity of Erg Echo for the diagnosis of CVS were 93% and 91% respectively. From 1990 to 1997, total 2,073 spasm provocation tests were performed either during invasive coronary angiography in the catheterization or in the echocardiography laboratory. Since 1994, noninvasive Erg Echo became a more popular diagnostic method and comprised more than 95% of all spasm provocation tests in recent 3 years. Erg Echo was also performed safely in outpatient clinic setting without hospital admission in 34% (500/1491). CONCLUSIONS: Erg Echo is highly feasible, accurate and safe for diagnosis of CVS and can replace the invasive spasm provocation test during coronary angiography in the catheterization laboratory.

Recently spondylolysis and spondylolisthesis have become major causes of low back pain in the orthopaedic field and numerous methods have been designed for its treatment. The authors used the LSDS with posterolateral fusion for 12 cases of spondylolisthesis and spondylolysis having low back pain and tenderness, which were operated on during the 4 years from Jan. 1983 to Jan. 1986 at Wallace Memorial Baptist Hospital. The advantages of LSDS with posterolateral fusion are as follows. l. In the case of distraction spondylodesis of interspinous process between L4 and Sl; A. the diameter of intervertebral formaina as well as of the whole spinal canal is widened. B. decompression is accomplished. C. the mechanical stress on the posterior columns of vertebral arch is lessened because the plumb line is anteriorly transferred. 2. Technique of LSDS; the knee-elbow position has the advantages of maximal kyphosis together with expansion of the space between the vertebral arches, as well as a reduction in the tendency to bleed because the blood collects in the abdominal vessels. 3. Internal fixation of grafted bone is not necessary. 4. A large surface area for unit mass of graft is in contact with blood supply. 5. Hypertrophy or displacement of graft can not encroach upon the epidural space; as may occur in certain circumstances following posterior fusion. The results of treatment are follows; l. In the case of improvement of symptoms after facet infiltration and knee-elbow position, satisfa- ctory results after LSDS were obtained. 2. The progression of slipping was not occurred after LSDS. 3. In increased lumbar lordosis, we have noted the instability especially with the changes from the mean values in Fergusons angles. 4. In the slip angle, there is some tendency to the lumbosacral instability correlating with the in- crease in the body weight. 5. We have also noted that the functional result was not closely related with degree of displacement.

A major problem in the repair of the torn Achilles tendon has been providing the restoration of the anatomic continuity such that virtually normal plantar flexion power and ankle mobility result. Continuity should be restored without subsequent pain, disconfiguration, occupational limitations. If possible, postoperative complications, or tendon-rerupture should be avoided. Surgeons have long advocated the use of strips of facia and other tissues, including the plantaris tendon, to reinforce the repair of the torn Achilles tendon, The repair effected by these methods not infrequently is bulky and not too secure. Non-absorbable suture materials utilizing in the end to end anastomosis of the torn Achilles tendon cause sinus formation and discharge of suture materials. A secure method of repair for the tom Achilles tendon, which decreases sinus formation and is not bulky, should be required. The plantaris tendon, which has been used as a reinforcing material, can be utilized in the end-to-end anastomosis of the torn Achilles tendon by detaching from the muculotendinous junction. The 11 patients with the torn Achilles tendon were treated by end-to-end anastomosis using the plantaris tendon as suture material. The postoperative results were staisfactory without significant functional deficit and complication.
