Fournier described five patients with gangrene of male external genitalia in 1883 and emphasized three characteristics: (1) abrupt onset in young healthy male, (2) rapid progression to gangrene,(3) absence of discernible cause. But more recent reports described genital gangrene as occurring in any age group and 4 patients in our cases, the mean age was 46 years with an age range of 31 to 59 years. Predisposing causes were as follows: case 1. prostatic calculi, Buerger's disease, case 2, perianal abscess, case 3, diabetes mellitus, case 4, tuberculous spondylitis accompanied by paraplegia and bed sores, liver cirrhosis. The duration of symptoms prior to the development of gangrene varied between 4 to 10 days. The cultured organisms were as follows : case 1. Alpha-hemolytic streptococcus, case 2. E. coli, Alpha-hemolytic streptococcus case 3. Alpha-hemolytic streptococcus, case 4, Mycobacterium tuberculosis, proteus species. Reconstructive surgery of defected scrotum was performed postoperative 8 to 41 days (mean 28.7) and total admission period was 25 to 83 days (mean 46 days).

Vibrio vulnificus infection is one of the most fatal diseases in Korea. This study was undertaken to determine the cellular fatty acid (CFA) compositions of ninety-five clinical strains of V. vulnificus isolated from Korea during 1985-1995. We compared these results with the CFA profile of V. vulnificus in the Microbial Identification System (MIS) (CLIN library version 3.9; Microbial ID Inc., Newark, Del.), and also evaluated the MIS ability to identify V. vulnificus. Subgrouping of V. vulnificus by CFA analysis was performed and its results were compared with those of serotyping. Most of the CFAs in V. vulnificus strains were similar to the CFA profile of V. vulnificus in the MIS, but some distinctive differences were observed. First, means of two major CFAs, 16:0 and 16:1w7c, were 22.16% and 18.26% in this study, but 23.52% and 25.44% in the MIS respectively. Second, all isolates had 11:Oiso3OH, which was not present in the MIS. Eighty-five strains (89.5%) disclosed the first choice identification of V. vulnificus by the MIS, but only two strains (2.1%) were identified with SI values of 0.6. Remaining ten strains (10.5%) showed 'NO MATCH' results. Cluster analysis of CFA could separate V. vulnificus into nine subgroups, and predominant subgroups were subgroup VII (45 strains) and V (36 strains). There was heterogeny between subgroups by CFA and serotypes of V. vulnificus. The strains of 04 serotype which accounted for 80% (76/95) of the isolates were distributed into six different subgroups such as VII (40 strains), V (27 strains), III (4 strains), I (2 strains) and VI (1 strain). These showed that V. vulnificus strains isolated from Korea had different characteristics in the CFA composition in comparison with the MIS V. vulnificus library. Subgrouping by the CFA analysis might be a useful tool for the epidemiological study of V. vulnificus infection in Korea.

BACKGROUND: The implementation of intraoperative normovolemic hemodilution is a strategy used in an attempt to diminish the need for or obviate allogeneic transfusion and to avert the potential complications. The goal of this study was to evaluate the safety and efficacy of moderate intraoperative normovolemic hemodilution. METHODS: Fifteen patients scheduled for posterolateral spinal fusion underwent intraoperative normovolemic hemodilution with 10% pentastarch to a target hematocrit level of 25% (hemodilution group). All units of blood procured by hemodilution and additional allogeneic blood was transfused in the perioperative period to maintain the hematocrit level of>25%. We investigated the effect of hemodilution on whole blood coagulation as measured by the thromboelastography and, evaluated its efficacy of decreasing the need for allogeneic blood transfusion as compared to the nonhemodilution group, retrospectively. RESULTS: Hemodilution with pentastarch caused a decrease in response and coagulation time (p<0.01) but did not influence on the alpha angle and maximum amplitude on thromboelstogram. Amount of transfusion of allogeneic blood was 4.1 1.7 units for the hemodilution group and 5.0 1.5 units for the nonhemodilution group. Net red blood cell volume ""saved"" from hemodilution was about 120 ml. CONCLUSION: Moderate intraoperative normovolemic hemodilution with pentastarch does not affect the coagulability of whole blood. But its efficacy of decreasing the need for allogeneic blood transfusion is minimal.

The antimicrobial agents reduced infectious diseases significantly. However, antibiotic resistance has followed for almost every antimicrobial agent. Especially, Staphylococcus aureus was one of the most notorious for the multidrug resistance. Streptomyces sp. 681 has been selected for antibiotic-producing strain against methicillin-resistant Staphylococcus aureus (MRSA) from 1,000 strains of Actinomycetales which had been isolated from soil. In antimicrobial susceptibility test, all of the test strains were susceptible to vancomycin. However, most strains of Staphylococcus aureus were found to be resistant to methicillin. Ninety eight (75%) strains out of 129 strains showed multiple resistance pattern to more than 5 antimicrobial agents. The MIC values of the purified antibiotic (K-681) were 1-32 ug/ml against Gram-positive bacteria compared to >128 ug/ml against Grarn-negative bacteria or fungi. The MIC was 8 ug/ml for 90% of the 129 clinical isolates of S. aureus. The antibiotic showed no cytotoxicity against P 388, HeLa, and S180 at the concentration of 500 ug/ml.

The p53 protein was discovered in 1979 as cellular 53-kD nuclear phosphoprotein bound to the large transforming antigen of SV40 virus. P21WAF1/CIP1, which has been described as the critical downstream mediator of p53, is known to suppress DNA replication and arrest the G1 cell cycle by quaternary complex with cyclin D, cyclin-dependent kinase(CDK) and proliferating cell nuclear antigen(PCNA). In these days, some studies shows that the p21 can be induced by independent pathways. There are various reports about the expression of p21 (67%.82.4%) in oral squamous cell carcinoma. But these studies are mostly done in malignant tumor not in benign tumor. So we decided to study the expression of p21 in ameloblastoma and the relationship between p53 and p21 as a downstream mediator of p53 in ameloblastoma. We investigated the expression of p21 and p53 with the method of immunohistochemistry. We selected 30 cases of ameloblastoma tissue blocks (acanthomatous type: 5 cases, follicular type: 8 cases, plexiform type: 17 cases) imbedded in paraffin. We used 30 cases of normal gingival tissues and 30 cases of squamous cell carcinoma tissues (SCC) respectively and compared their results with those of ameloblastoma. We made slides with the streptavidin-biotin methods and used monoclonal antibody DO-7 (Novocastra, Newcastle, United Kingdom) as p53 antibody and monoclonal antibody M7202 (DAKO, California, U.S.A.) as p21 antibody. We used Pearson's correlation coefficient to analyse the relationship. The results were as follows: 1. p21 was expressed in ameloblastoma about 30% and this is lower than that of normal gingiva and SCC. 2. In normal gingiva and ameloblastoma, p21 expression was correlated with p53 expression. 3. In SCC, p21 were expressed about 83.3% and this is more than that of p53. But there was no correlation between p21 and p53 expression. We confirmed p21 expression and relation with p53 in ameloblastoma. But, to confirm the function of p21, more studies about p21 expression in malignant ameloblastoma and ameloblastic carcinoma are needed.

There were 18 woman with mild to moderate stress incontinence treated with the Sympathomimetic agents, with were combined with phenylpropanolamine hydrochloride, chlorpheniramine maleate, and isopropamide. The majority of these patients achieved significant improvement for 2 months to 2 and half years after beginning therapy. These patients were performed physical examination, voiding cystourethrogram, stress test lateral-chain cystourethrogram, cystoscopy in order to confirm stress incontinence. We thinked that these conservative therapy were advisable for stress incontinence especially when symptoms were mild.
