BACKGROUND: To access the accuracy and clinical usefulness of microplate identification (ID) system for the identification of Enterobacteriaceae, we compared microplate ID system with API 20E(bioMerieux, Etoile, France). METHODS: Ninety-two cultures of Enterobacteriaceae and one isolate of Aeromonas species were simultaneously identified by microplate ID system and the API 20E. Twenty biochemical tests used in microplate ID system were lactose, sucrose, and H2S in Kligler's iron agar media; indole, sucrose, raffinose, arabinose, trehalose, adonitol, dulcitol, sorbitol, cellibiose, methy-red, phenylalanine deaminase, ornithine decarboxylase, lysine decarboxylase, arginine dihydrolase, urease, and citrate in microplate; and oxidase test. The identification was obtained by considering percent likelihood(% ID), modal frequency and ID score method. RESULTS: Among the 92 cultures of Enterobacteriaceae and one isolate of Aeromonas species, agreement rate of identification according to the % ID between microplate ID system and API 20E were 90.3% to the species level and 97.8% to the genus level. CONCLUSIONS: For the identification of clinical Enterobacteriaceae isolates, the microplate ID system compares favorably with API 20E in identification accuracy and have the advantage of costsaving and easy to use.

We report a cace of 69-year-old man who developed massive pulmonary hemorrhage and subsuquent adult respiratory distress syndrome following intravenous urokinase for acute myocardial infarction. Pulmonary hemorrhage is a rare but a potentially life-threatening complication after thrombolytic therapy and should be considered in the differential diagnosis of pulmonary infiltrates of falling hemoglobin after thrombolytic therapy for acute myocardial infarction with no obvious site of bleeding.

OBJECTIVES: Schizophrenia manifests a variety of interindividual differences in therapeutic response to antipsychotics. This might be attributable to dopamine and serotonin receptors that a important target for various antipsychotics, and the D3 receptor(DRD3) alleles they carry. The purpose of our study was to investigate whether the plasma levels of homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(HIAA), and the polymorphism of DRD3 can be held as a predictor of treatment response ni chronic schizophrenic patients. METHODS: Therapeutic response for 16 korean schizophrenia patient treated during 48 weeks were assessed by PANSS used as the clinical symptom rating scales. The levels of concentration of HVA and 5-HIAA were examined by HPLC at baseline and at 48 weeks. We classified the polymorphism of DRD3 receptor using amplifying by polymerase chain reaction(PCR). RESULTS: Neither concentrations of HVA and 5-HIAA nor genotype of dopamine 3 receptor were not significantly associated with the therapeutic response. But, the patients who has A1 alleles of DRD3 gene showed poor therapeutic responses. CONCLUSION: A1 allele of DRD3 gene is associated with poor prognosis of chronic schizophrenia.

PURPOSE: To compare dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) and investigate the influence of central corneal thickness (CCT) onintraocular pressure. METHODS: In a prospective study of 165 eyes with glaucoma (135 eyes), glaucoma suspect (14 eyes), and ocular hypertension (16 eyes), intraocularpressure was measured with DCT and GAT, and followed by measurement of the CCT with ultrasound pachymetry. Statistical analysis were performed with simple linear regression analysis and t-test using SPSS (Statistical software, ver. 10; SPSS Inc., Chicago, IL). RESULTS: A clear correlation between DCT and GAT was found (r=0.733, p<0.001). The average intraocular pressure was 14.92+/-2.28 mmHg with DCT and 13.97+/-3.12 mmHg with GAT, and the intraocular pressure with DCT was 0.95+/-2.49 mmHg higher than with GAT. A meaningful correlation was shown between GAT and CCT (r2=0.145, p<0.001), but was not demonstrated between DCT and CCT (r2=0.012, p=0.081). In addition, the difference of intraocular pressure between GAT and DCT (GAT-DCT) showed a significant correlation with CCT (r2=0.145, p<0.001). CONCLUSIONS: DCT appears to be a reliable method for intraocular pressure measurement, which is not influenced by CCT, unlike GAT.

The squamous cell carcinoma of the uterine cervix is the most common malignant tumor among women in Korea. Since 1976, when a research result that human papillomavirus(HPV) infection played some role in the carcinogenesis of the uterine cervical carcinoma had been published, numerous reports supporting the result have been released. Among the types of the HPV, type 16 and type 18 are classified as high risk types because they are frequently found in cervical lesions with high grade dysplasia and invasive carcinomas. However, it is impossible to ascertain by host histologic or cellular changes which type of HPV is infected. The HPV genome is composed of six open reading frames (ORF' s) named as E1, E2, E4, E5, E6 and E7 in the early region. Among these oncoproteins HPV E6/E7 have been strongly suggested to be important in carcinogenesis. When HPV infects the epithelial cells, it promotes cellular proliferation. The cellular proliferation can be evaluated by immunohistochemistry with the antibodies for proliferating cell nuclear antigen(PCNA) and Ki-67. Because PCNA has long half-life, and can be detected 48 hours after completion of mitosis, an estimation of proliferating cells by PCNA could be inaccurate. The expression of Ki-67 antigen is more correct than PCNA for the evaluation of proliferation cells due to its short half-life and rapid degradation after completion of the mitosis. In this study, immunohistochemical staining was conducted to determine the rate of expression of HPV E6, E7 and Ki-67, correlation with relationship in carcinoma in situ and invasive uterine cervical cancer. Fifty cases of carcinoma of in situ(CIS) and invasive carcinoma were immunohistochemically stained, and the results obtained were as follows: 1) E6 protein of HPV type 16/18 was expressed in 5 of 14 cases(35.7%) of carcinoma in situ, in 3 of 7 cases of microinvasive carcinoma (42.8%) and in 12 of 20 cases of invasive carcinoma(60%) but there was no significant difference in expression between the carcinoma in situ and invasive cancer group (p=0.138). 2) E7 protein of HPV type 16/18 was expressed in 10 of 14 cases(71.4%) of carcinoma in situ, in 6 of 7 cases of microinvasive carcinoma (85.7%), and in 18 of 20 cases of invasive carcinoma(90%) but there was no significant difference in expression between the carcinoma in situ and invasive cancer group (p=0.138). 3) The cell fraction expressing Ki-67 was expressed in 5 of 14 cases(35.7%) of carcinoma in situ, in 5 of 7 cases of microinvasive carcinoma (71.4%), and in 18 of 20 cases of invasive carcinoma.(90%) The cell fraction expressing Ki-67 increased according to the progress of cervical cancer. 4) There was no statistical significance between HPV type 16/18 E6 protein and the cell fraction expressing Ki-67(p=0.09). 5) There was no statistical significance between HPV type 16/18 E7 protein and the cell fraction expressing Ki-67(p=0.17). The above results suggest that the cell fraction expressing Ki-67 increases according to the invasiveness of cervical cancer and E6/E7 protein seem to play a role in the progression of cervical cancer. However we were not able to reveal a relation between E6/E7 protein and the cell fraction expressing Ki-67 in progress of cervical carcinoma, and it is recommended that further studies should be undertaken.

PURPOSE: The chemical sympathectomy is now widely performed procedure for vascular diseases of extremities. But it has been reported that this procedure may produce ejaculatory failure in men. We investigated the changes of the contractility of the vas deferens after chemical sympathectomy by 6-hydroxydopamine, and whether these changes can be recovered by the pretreatment of testosterone. MATERIALS AND METHODS: The rats were divided into 5 groups, which were 1) control 2) 6-hydroxydopamine 100mg group 3) 6-hydroxydopamine 100mg + testosterone100mg group 4) 6-hydroxydopamine 200mg group 5) 6-hydroxydopamine 200mg + testosterone 100mg group. 6-hydroxydopamine was injected intraperitoneally in each group at day 1, 3, 5 and killed at day 6. Testosterone was Injected intraperitoneally 30 minutes prior to 6-hydroxydopamine injection at day 1 . The vas deferns was quickly dissected out and the contractilities by electrical field stimulation, phenylephrine, acetylcholine and KCI were compared with control group. RESULTS: In prostatic vas, the phasic contractions were reduced only in 6-hydroxy- dopamine 200mg group and recovered incompletely by testosterone. Tonic contractions in prostatic vats were reduced in 6-hydroxydopamine looms group and 6-hydroxydopamine 100mg+testosterone 100mg group at 4, 8, 16Hz field stimulation and there was no significant difference between the two groups. The contractilies in 6-hydroxydopamine 200mg group and 6-hydroxydopamine 200mg+testosterone 100mg group were reduced at all frequencies, and testosterone pretreatment group showed slightly recovered contractility at 32, 64Hz, but less than those of control. In epididymal vas, the phasic and tonic contractions were reduced in all groups compared to control except in 6-hydroxydopamine 100mg+testosterone looms group at 32, 64Hz. The effects of 6-hydroxydopamine on phenylephrine or acetylcholine induced contraction showed supersensitivity, however, testosterone pretreatments had no effects on their supersensitivity. In the response to KCI, there was no difference in all the experimental groups. CONCLUSIONS: It seems that chemical sympathectomy results in decreased contraction of the vas deferens, which is the main cause of ejaculatory failure. Although there is some protective effect by testosterone pretreatment, but it is thought that it is not so sufficient to prevent ejaculatory failure. But we suggest that there are possibilities of protective effect of testosterone by altering the dose and time of administration.

OBJECTIVE: We retrospectively analyzed the surgical outcomes of 42 patients with growth hormone (GH)-secreting pituitary adenoma to evaluate the clinical manifestations and to determine which preoperative factors that significantly influence the remission. METHODS: Forty-two patients with GH-secreting pituitary adenoma underwent transsphenoidal surgery (TSS) between 1995 and 2007. The patient group included 23 women and 19 men, with a mean age of 40.2 (range 13-61) years, and a mean follow-up duration of 49.4 (range 3-178) months after the operation. For comparable radiological criteria, we classified parasellar growth into five grades according to the Knosp classification. We analyzed the surgical results of the patients according to the most recent stringent criteria for cure. RESULTS: The overall rate of endocrinological remission in the group of 42 patients after primary TSS was 64% (26 of 42). The remission rate was 67% (8 of 12) for microadenoma and 60% (18 of 30) for macroadenoma. The remission rate was 30% (3 of 10) for the group with cavernous sinus invasion and 72% (23 of 32) for the group with intact cavernous sinus. Cavernous sinus invasion in Knosp grade III and IV was significantly correlated with the remission rate. There was a significant relationship between preoperative mean GH concentration and early postoperative outcome, with most patients in remission having a lower preoperative GH concentration. CONCLUSION: TSS is thought to be an effective primary treatment for GH-secreting pituitary adenomas according to the most recent criteria of cure. Because the remission rate in cases with cavernous sinus invasion is very low, early detection of the tumor before it extends into the cavernous sinus and a long-term endocrinological and radiological follow-up are necessary in order to improve the remission rate of acromegaly.
