The recent discovery of plasmid derived beta-lactamase production by N. gonorrhoeae has changed the outlook of treatment of gonococcal infections and may well become the single most important factor in gonorrhoea control. Penicillinase is a beta-lactamase that splits the beta-lactam ring of penicillin hetween the C and N atoms to form penicilloic acids. We have been trying to assess the prevalence of PPNG in Korea since May 1980. We report here 7 strains of beta-lactamase producing N. gonorrhoae detected by chrornogenic cephalosporin method from Jan. 1981 to Mar. 1981 at the Joong Ku puhlic health center in Seoul. In January, I strain (l.3%); February, 2 strains (5.0%); and March, 4 strains .(6 4%) have been isolated. All restrains were confirmed by sugar feriventation test. Previously only one strain of PPNG had been reported among Korean laymen. The sudden appearance of PPNG among Korean laymen in 1981 may mean the barruer between U.S. Army enc1aves and Korean public has been broken recently and/or direct irnport of PPNG frorn abroad especially from South East Asia.

OBJECTIVE: To determine the fetal aneuploidy in fetal blood cells from cordocentesis. METHODS: We analyzed their karyotype and performed fluorescence in situ hybridization(FISH) for chromosome 18, 21, X, and Y in 14 cases of fetal blood cells from cordocentesis at Department of Obstetrics & Gynecology, College of Medicine, Seoul National University and Hamchoon Women's Clinic. RESULTS: In all cases we obtained the consistent results in both methods and were able to rapidly detect aneuploidy in uncultured fetal blood cells using FISH before karyotyping with culture for 48 hr. The averages for accuracy of FISH were from 84.6 % to 93.9%. CONCLUSION: In this study we suggest that the rapid detection in uncultured fetal blood using FISH is possible and that this diagnostic method will be clinically useful when rapid result would be demanded.

FISH is suggested as a possible method to detect the numerical and structural abnormalities of chromosomes in interphase nucleus. We performed this study to discuss the clinical usefulness of FISH in uncultured amniocytes and to set up the cut-off value for further study. We collected amniotic fluid samples from patients whose chromosome studies were recommended due to screen positive for Down and Edword syndrome in triple marker test using maternal serum. The centromeric probe for chromosome 18 and the locus-specific probe for chromosome 21 were used and the results were compared to their karyotypes. We could find 2 cases of trisony 21 and 2 cases of trisony 18 and the other cases represented normal karyotypes. The accuracies were 91% for disomy 18, 89% for trisomy 18, 92% for disomy 21 and 88% for trisomy 21. Therefore FISH technique is a possible method to detect the chromosomal abnormalities in uncultured amniocytes and the use of locus-specific probe for chromosome 21 would be more useful for detecting the aneuploidy of chromosome 21 than 13/21 centromeric probe.

The authors have experienced a case of extrascleral extension of choroidal malignant melanoma. The patient has suffered from the ocular pain and proptosis of right eye. We performed Kronlein operation under the clinical impression of the retrobulbar mass and obtained the histopathological diagnosis of malignant melanoma. Fifteen days after the operation, we performed exenteration and the rotation flap of temporalis muscle was inserted into the right eye ball socket through the lateral wall of the orbit.

OBJECTIVE: To investigate cortical reorganization of the brain during voluntary activities of the hand in patients with subcortical cerebral infarction. METHOD: Twelve patients with first-ever subcortical brain lesion causing hemiparesis had been evaluated with functional MRI. Bilateral hand clenching was done to test voluntary hand activities. Recovery period ranged from 2 to 36 months. RESULTS: During the unaffected hand movement, activation of contralateral primary sensorimotor cortex (SMC) were recorded in all cases and supplmentary motor area (SMA) in 1 case. The affected hand movement showed activation of the cotralateral SMC in all cases, ipsilateral SMC in 4 cases, SMA in 4 cases and contralateral prefrontal area in 2 cases. As for the contralateral SMC, affected hand movement showed more increased activation than the unaffected. For the bilateral SMC activation during movement of the affected hand, contralateral SMC activation was greater than the ipsilateral. CONCLUSION: Ipsilateral activation of the SMC, SMA, prefrontal area and increased activation of the contralateral SMC during affected hand movement suggest that these may play an important role in the reorganization of sensory and motor system in stroke patients with subcortical lesion. Functional MRI studies of patients who recovered from subcortical stroke provide evidence for several process that may be related to restoration of neurologic function.

OBJECTIVE: To investigate the effect of environmental factors on the ability of mobility in subjects with chronic stroke who can perform nearly independent activities of daily living (ADL). METHOD: Sixty one patients were divided into three groups (superior, middle, and inferior) by the degree of independent walking. Modified self-administered questionnaire was completed to report how well the patients encountered the environmental elements faced in community mobility. In addition, all patients were assessed to find out the difference of ADL performance, Berg balance scale (BBS), 10 m walking time (10 mWT) and patterns of 'going out' among the three groups. RESULTS: The group 1 (superior group) had shown better performance than group 2 (middle group) and group 3 (inferior group) in performance of ADL, BBS, 10 mWT. Secondly, the group 1 visited more places or destinations per day than the group 2 and 3, and they used more various transportation systems than other groups. Finally, there were significant differences in the distance dimension, the temporal dimension, terrain dimension (except for a 'getting on a elevator' component), and density dimension among the groups. CONCLUSION: Environmental factors as well as functional abilities could affect the mobility of subjects with chronic stroke. This result suggests that any kinds of compensation and the supports of social institutions are needed even in subjects of nearly independent ADL for their improvement of mobility and convenience.

OBJECTIVE: Ovarian cancer is common a gynecologic malignancy and leading cause of death in women being diagnosed with advanced disease. This study was undertaken to investigate the roles of the proteins related to G1 cell cycle in ovarian carcinogenesis. METHODS: The expression of cyclin Dl, p16, RB and PCNA in DMBA (7, 12-dimethylbenzanthracene)-induced ovarian cancer of rats was analyzed by immuno-histochemistry and Western blot. RESULTS: 1. Twenty-nine tumors were induced in 32 ovaries from 16 rats (90.6%) in the experimental group. The average weight of tumor was 3.35+/-0.73 gm and the average size was 1.84+/-0.17 cm in greatest dimension. The histologic types were adenocarcinomas (n=20), squamous cell carcinomas (n=3), sarcoma (n=4) and combined types (n=3). 2. With respect to the cyclin D1 and PCNA labelling index, ovarian cancers showed significantly higher index than normal ovarian surface epithelium. There were no differences among the cancer types. In Western blot analysis, the expression of cyclin Dl in ovarian cancers was higher than that in normal ovarian surface epithelium. 3. With respect to the p16 and RB labelling index, ovarian cancers showed significantly lower index than normal ovarian surface epithelium. There were no differences among the cancer types. In Western blot analysis, the expression of cyclin Dl in ovarian cancers were lower than that in normal ovarian surface epithelium. 4. Positive correlation was shown among cyclin D1, PCNA. RB was negatively correlated with cyclin D1, PCNA. The p16 had no correlation with cyclin D1, PCNA. CONCLUSION: These results suggest that the deregulation of cyclin Dl, p16, RB and PCNA occur in DMBA induced rat ovarian carcinogenesis and result in tumor progression. Further studies are needed to investigate the role and function of cyclin Dl-p16-RB pathway in human ovarian cancer with this animal model.

PURPOSE: Diverticular disease of the cecum and ascending colon is a relatively uncommon disease and there are some difficulties in the accurate preoperative diagnosis and the proper surgical treatment. This study is aimed to determine what is the proper procedure during the emergency operation of right colon diverticulitis. METHODS: This study is a retrospective clinical analysis of 86 cases of the right colon diverticulitis from January 1992 to December 1999. RESULTS: 1) The incidence of right colon diverticulitis (RCD) was 2.1% of that of appendicitis and the RCD to sigmoid colon diverticulitis ratio was 9.6:1.2) The highest incidence was noted at the fourth decades and average age was 37 years. Male to female ratio was 1.9:1. 3) Most patients (73 cases, 85%) had right lower quadrant abdominal pain. 4) The duration of symptom was less than 3 days in 54 cases (63%). 5) The preoperative confirmation by radiologic work-up was not decisive, but barium enema might be more accurate than other studies and CT was more accurate method than ultrasound. 6) The correct preoperative diagnosis was made only in 13 cases (15%) and the remaining misdiagnoses were appendicitis with or without complications in 72 cases (83%). 7) Operative procedures varied markedly according to multiplicity, extent of inflammation and complications; diverticulectomy and appendectomy in 48 cases (56%), ileocecectomy in 15 cases (17%) and right hemicolectomy in 11 cases (13%). 8) The most commom postoperative complication was wound infection. 9) Among the 30 cases who took diverticulectomy or diverticulectomy and appendectomy, remained diverticulums were found in 14 cases (47%), especially 11 cases (37%) on the right colon. And so multiplicity of right colon reached about 37%. CONCLUSIONS: The authors suggest that one should suspect RCD in fourth decade patients with right lower quadrant pain for more than 3 days with unusual clinical findings. Barium enema can be used because of the high accuracy rate but CT is a safe tool in complicated or urgent situation. The operative modalities should be selected on the extent of the disease and it is sufficient to treat a single diverticulitis with diverticulectomy or diverticulectomy and appendectomy but right hemicolectomy should be recommanded in the suspicious multiplicity or malignancy.

OBJECTIVE: Surgical treatment of posterior inferior cerebellar artery (PICA) aneurysms is challenging due to limited surgical accessibility. Endovascular approach has a benefit of avoiding direct injury to the brainstem or lower cranial nerves. Therefore, it has recently been considered an alternative or primary modality for PICA aneurysms. We retrospectively assessed outcomes following detachable coil embolization of saccular PICA aneurysms. METHODS: From February 1997 to December 2007, we performed endovascular procedures to treat 15 patients with 15 PICA aneurysms. Fourteen patients with 14 PICA aneurysms morphology of which was saccular were reviewed retrospectively. Twelve patients had ruptured aneurysms. The aneurysms arose from the PICA origin site (n = 12), the PICA lateral medullary segment (n = 1), or the PICA tonsilomedullary segment (n = 1). RESULTS: Complete aneurysm occlusion was achieved in 10 patients, residual neck in 3, and residual sac in one. Radiological follow-up was performed in 7 patients with mean duration of 34.7 months (range, 1-97 months) and showed stable or complete occlusion in 6 patients. There were no rebleeding or retreatment after endovascular treatment. Thromboembolism was the only procedure-related complication (n = 4 ; 28.6%). Asymptomatic PICA infarction occurred in two patients and symptomatic PICA infarction in two elderly patients with poor clinical grade. Of these procedural PICA infarction cases, 1 symptomatic PICA infarction patient developed ventriculitis and septic shock leading to death. The clinical outcome was good in 10 patients (71.4%). Conclusions: In the present study, detachable coil embolization has shown as an efficient modality for PICA saccular aneurysms challenging indications of microsurgery. However, thromboembolic complications should be considered, especially in poor clinical elderly patients with ruptured aneurysms.

Emphysematous prostatic abscess is a very rare form of prostatitis. Emphysematous prostatic abscess due to Klebsiella pneumoniae may have a poor prognosis according to a few previous reports. We report a rare case of successfully treated emphysematous prostatic abscess with cystitis due to Klebsiella pneumoniae in a 50-yr-old man with 15-yr history of diabetes mellitus. The patient was referred to the emergency room of our hospital. The KUB film revealed gas shadows in the lower pelvic area suggestive of emphysematous cystitis or emphysematous prostatic abscess. The gas was mainly occupying the prostate and was also seen in the bladder on pelvic CT. The patient was successfully treated with long-term antibiotic use and additional percutaneous drainage of the abscess. Emphysematous prostatic abscess may be misdiagnosed as emphysematous cystitis due to the similar location of gas shadows on radiography. Computerized tomography and transrectal ultrasonography are helpful in making the diagnosis of emphysematous prostatic abscess. Appropriate use of effective antibiotics with drainage of pus is the best treatment. This case emphasizes the importance of timely and accurate diagnosis followed by appropriate treatment in emphysematous prostatic abscess in diabetic patients.
