The range of acetabular cup and femoral prosthesis according to the different angle of insertion has been reported by many investigators. But no reports are still avairable about the surface area of the exposed femoral head at the position causing unstability of the femoral head. So the authors had studied the 3 types of prosthesis of Charnley, Muller and Mckee-Farrar and their acetabular cup by inserting them at different angles into the 10 human cadavaric skeleton to obtain the most stable position of the prosthesis and to calculate the surface area of the femoral head at the stable position. The result obtained are as follows. 1. In. Flexion: Among 3 types of prosthesis, the maximum stability is 78% to the exposed area of the femoral head in Mckee-Farrar prosthesis with 10 of the femoral anteversion, 45 of acetabular inclination and 45 of acetabular anteversion. The minimum stability is 41% to the exposed area of the femoral head in Mckee-Farrar prothesis with femoral neutral version, 45 of acetabular inclination and 15 of acetabular retroversion. 2. In Abduction: Among 3 types of prosthesis, the maximum stability is 86.5% to the exposed area of the femoral head in Mckee-Farrar prosthesis with 10 of the femoral anteversion, 45 of acetabular inclination and 45 of acetabular anteversion. The minimum stability is 50% to the exposed area of the femoral head in Muller prosthesis with femoral neutral version, 45 of acetabular inclination and 30 of acetabular retroversion. 3. In External Rotation: Among 3 types of prosthesis, the maximum stability is 85. 8% to the exposed area of the femoral head in Mckee-Farrar prostbesis with femoral neutral version, 45 of acetabular inclination and 30 of acetabular retroversion. The minimum stability is 46% to the exposed area of the femoral head in Mckee-Farrar prosthesis with femoral neutral version, 30 of acetabular inclination and acetabular neutral version. 4. There was no relationship between the degree of range of the femoral prosthesis & acetabular cup and the amount of the surface area of the exposed femoral head when dislocated.

This is a retrospective review of 11patients of type II SLAP lesion which were found during arthroscopic treatment of 26 patients diagnosed SLAP lesion, clinically and radiologically, hetween March l989 and June 1996. Follow-up time was averaged 26 months (range, l2 months to 72 months) and average age was 30 years old. All patients were treated arthroscopically for SLAP lesion. In type II 2 cases were repaired hy biodegradable tacks (Suretac(R)), 9 cases were repaired by transglenoid and transscapular tcchnique that included dehridement of the frayed lahrum and ahrasion of the superior glenoid neck, followed hy the placement of multiple suture on the torn capsular-labrum complex and lahrum-biccps tendon complex using suture hook, heath pin and # 0 PDS (Rhee's method). Among 9 cases with transglenoid and transscapular suture technique in type II SLAP lesion, the result were quantitated with Rowe ratin scale, 4 cases were exellent, 3 cases were good and 2 cases were fair. Our modification technique, using transglenoidal two bone hole technique and tying on scapular spine can ohtain as compatible fixation as other techniques which include metal staple, bioderadahle tacks (Suretac(R)) and anterior anchoring system such as mini-Revo. Our technique also has reasonable recurrence rate with few complication. The advantage of our modified technique is able to do superior capsular advancement, capsular plication and capsular shift which procedures are very difficult in other techniques. We propose arthroscopic transglenoid and transscapular suture technique (Rhee's method) for type II SLAP lesion as one of new method of suture for type II SLAP lesion.

Ceftizoxime sodium is a new synthetic β-lactam antibiotic combining potent antibacterial activity with high stability to a wide range of bacterial β-lactamase. This experiment was achieved to evaluate the antibacterial activities of ceftizoxime sodium against. Gram negative enteric bacteria isolated from in outpatient visiting Yeungnam university hospital and to study the emergence of drug induced bacterial variants which resist to ceftizoxime in vitro. The antibacterial activity of the ceftizoxime was compared with that of antibiotics and its effect on population of normal intestinal flora in mice was observed. The results are summarized as follows: 1. Highly effective antibacterial activity of ceftizoxime against Gram negative enteric bacilli was demonstrated and this antibacterial activity was superior to that of ampicillin. 2. Several test strains shows multiple antibiotic resistance. Among 15 strains of Escherichia coli, 1 strain was resistant to ampicillin, cefadroxil, gentamicin, tetracycline, and 2 strains were resistant to ampicillin, cefadroxil, tetracycline, five strains of Escherichia coli and Enterobacter cloacae was resistant to ampicillin, tetracycline and Shigella dysenteriae was resistant to ampicillin, gentamicin, tetracycline. 3. The frequency of in vitro emergence of resistant variants among ceftizoxime sensitive bacteria in the presence of increasing concentrations of the compound was found to be low. 4. Plasmid was isolated in 6 of 9 strains (6 strains of Escherichia coli, Shigella dysenteriae, Enterobacter cloacae and Salmonella typhi). That showed different antibiotic resistance. They were 5 strains of Escherichia coli and 1 strain of Shigella dysenteriae. However, plasmid could not be considered as a hallmark for antibiotic resistance by this Further studies with curing experiment are to be accomplished for this purpose. 5. Changes in the bacterial count of normal intestinal flora following 25 mg/kg/day administration of ceftizoxime over 5 consecutive days were not significant. In conclusion, ceftizoxime appeared to be a drug of choice in the treatment of Gram negative enteric bacilli infection.

OBJECTIVE: This study was designed to evaluate the efficiency of tumor markers level for early diagnosis of ovarian malignancy and for differentiation between benign and malignant ovarian tumors. MATERIALS AND METHODS: We determined preoperative serum tumor markers level in patients who were going to have an operation due to ovarian tumor in OB & GY Dept. of Chonnam University Hospital from April 1993 to September 1999. RESULTS: 1) The average values of serum tumor markers in patients with malingnant ovarian tumors were statistically higher than those of benign ovarian tumors. among malignant ovarian tumors, positive rate of all serum tumor markers was highest in epithelial ovarian carcinoma group. and among ovarian tumor markers, and positive rate of CA 125 was highest in epithelial ovarian carcinoma. 2) Dermoid cyst and endometioma were correlated to CA 19-9, CA 125 levels respectively. for malignant tumors, mucinous ovarian adenocarcinoma and non-mucinous ovarian adenocarcinoma were CA 19-9, CA 125 levels respectively. 3) Among ovarian tumor markers, CA 125 was the most in sensitivity and CA 72-4 was the most in specificity and diagnostic efficiency. 4) For postmenopausal women with ovarian tumors, elevated levels of at least one of the 4 tumor markers were present in the serum in 85.7% of the women who developed cancer, 62.5% of women with borderline, 27.8% of women with benign ovarian tumors. Conclusion; It is suggested that determination of serum tumor markers in patient suspected of ovarian tumor may be helpful to clinician for early diagnosis, differentiation between malignant and benign ovarian tumors.

OBJECTIVE: To investigate the response of hyperplastic endometrium to Medroxyprogesterone acetate according to the histologic types such as simple typical, complex typical and atypical hyperplasia. METHODS: A total of 79 patients with histologically proved endometrial hyperplasia were enrolled into this prospective study between March 1996 and May 1998. Patients without atypia were placed on a regimen of cyclic therapy with 10mg MPA orally, each day for 14days per month for 3 months. In the cases in which hyperplasia did not regress , MPA was increased to 20mg. Patients with atypical hyperplasia received continuous MPA therapy, 20mg orally each day for 3 month. All patients were followed up for a minimum of 3 months and a maximum of 1 year(mean 7 months). RESULTS: In patients with simple typical hyperplasia, 45 patients(80.4%) had regression, 11 patients(19.6%) had persistence and none had progression. In patients with complex typical hyperplasia, 10 patients(83.3%) had regression, 2 patients(16.7%) had persistence and none had progression. But, in patients with atypical hyperplasia 5 patients(45.4%) had regression, 4 patients(36.4%) had persistence and 2(18.2%) patients had well differentiated endometrial adenocarcinoma. There was no recurrence during the follow up. CONCLUSION: This data suggest that most women with typical hyperplasia respond to progestin therapy, but there is high failure rate of response to progestin therapy and risk of endometrial cancer in patients with atypical hyperplasia. If the young patient desires to preserve her fertility, then progestin therapy may be considered as primary treatment in patients with atypical hyperplasia. But older patients in whom fertility is not an issue, hysterectomy should be selected as treatment of choice for atypical lesion.
