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.

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.

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.

OBJECTIVES: This study was carried out to evaluate the effects of industrial noise on blood pressure and heart rate. METHODS: Resting blood pressure, hearing loss, and general characteristics of the 102 subjects who were engaged in a factory in Pusan were measured from March to June for two years, in 1998 and 1999. With noise dosimeter, noise exposure level was measured from 8 A.M. to 4 P.M. Ambulatory blood pressure and heart rate were also measured every 30 minutes from 8 A.M. to 10 P. M. RESULTS: Controlling for age, smoking, and Quetelet's index, in subjects of under 40 years old exposed to higher than 85dBA, noise exposure and systolic blood pressure had a statistically significant correlation, and the same result was obtained in all subjects. The daily variability of ambulatory blood pressure and heart rate were observed in older than 40 years old group, but only heart rate in under 40 years old. CONCLUSIONS: The blood pressure and heart rate would be elevated when the workers exposed to noise. And in under 40 years old, the systolic blood pressure was elevated to the workers exposed to higher than 85dBA.

It should be stressed that intracranial tumors in childhood are common. If the leukemia are excluded, intracranial neoplasms are the relatively common type of neoplasms seen in childhood. There are many different kinds of tumor which occur within the cranial cavity. These different tumors grow at different rates of speed and the diversity of location is sufficient so that there is a broad spectrum of different clinical syndromes. However, it is important to recognize the earliest symptoms because of the possibility of operable management and high cure rate on some cases. The author analyzed 58 cases of intracranial neoplasm which were histologically confirmed after operation and autopsy, seen at the Department of Neurosurgery, Jung-Ang University, Sung-Sim Hospital and National Medical Center over the recent several years. These tumors were explored surgically and the diagnosis was made through histological examination. The cases were reviewed as to history, development and progression of the neurological features, laboratory findings, neuroradiological findings, operative methods and pathology. The author emphasized some interesting points and the following were presented here-in as the results. 1) Among 58 cases of intracranial neoplasms in Korean children below 15 years old, the most common tumor was astrocytoma(36%), and the next common tumors were craniopharyngioma(15.5%), ependymoma(12%), and medulloblastoma(10.3%) in that orders. It was interesting that 3 cases of tuberculomas were found in recent three years(1975-1977) and all were located in the cerebellum. A 5 years old boy who was operated for 4 th. Ventricle medulloblastoma confirmed by clinicopathological finding, had another tumor, craniopharyngioma which was found at the postmortem examination. 2) The tumors were occupied on the infratentorial region in 30(5.7%) cases and supratentorial region in 28(48.3%) cases. The most frequent tumor in supratentorial region was craniopharyngioma and in infratentorial region was cerebellar astrocytoma. And the glioma and medulloblatoma were common in turn. 3) Fifty eight cases comprised 36 males and 22 females with a ratio of 1.5 to 1. The age ranged from 5 months old to 15 years old with the peak in the incidence between 5-11 years of age. 4) The main clinical symptoms and signs were headache(84.5%), vomiting(77.6%), papilledema(67.2%), and cranial nerve dysfunction(62%). It was interesting points that neck stiffness(27.6%) and abdominal pain(15.5%) were frequent complaints which should not overlook for the symptoms of simple gastritis or tuberculous meningitis. 5) The results of operative management obtained as follows with excellent in 4, good in 8, fair in 13, and poor in 9 cases. The overall mortality rare was 41% and recurrence rate was 14% during 5 years follow up.

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.

This is retrospective study of the 18 patients of SLAP lesion which were found during arthroscopic treatment of 92 patients. The patients were diagnosed as recurrent shoulder dislocation (50 patients), shoulder impingement syndrome (36 patients) and SLAP lesion (four patients), clinically and radiologically, between March 1989 and June 1995. SLAP lesion were found in eleven patients with recurrent shoulder dislocation, three patients with impingement syndromes. Solitary SLAP lesions were found in four patients. Mean follow-up time was 36 months (range, 12 to 72 months) and average age of patients were 26 years old. Type I SLAP lesion by Snyder's classification were eight cases, type II were seven cases, type III were two cases and type IV was one case. Arthroscopic debridement of frayed or degenerated labrum and biceps tendon anchor were per formed in ten cases of type I and III. In type II and IV, six cases were repaired by arthroscopic placement of multiple suture, two cases were repaired by biodegradable tack (Suretac). The result were quantitated with Rowe rating scale. Eleven cases were exellent, four cases were good, and three cases were fair with Rowe rating scale. Our study revealed that these lesions were not uncommon in instability or impingement of shoulder. Type II SLAP lesion was frequently associated with anterior shoulder instability.
