To evaluate the degree of competitive exclusion against Salmonella gallinarum(S. gallinarum) of Salmonella enteritidis(S. enteritidis) infected chickens, fifty-six, 4-week old Hyline layer suspected of S. enteritidis infection were challenged with S. gallinarum. All chickens were tested for S. enteritidis isolation using cloacal swabs and serum plate agglutination test using S. enteritidis Ag. before challenge and classified into four groups(SE isolated, SE nonisolated, SE seropositive and SE seronegative). None of the SE isolated and the SE seropositive groups died after challenge and the average weight gains were 245.5g and 254.6g, respectively. But in the SE nonisolated and the SE seronegative groups, mortality was 18.2% and 20.6% and the average weight gains were 150.1g and 111.2g. The incidence of reisolation of S. gallinarum of the SE isolated and the SE seropositive groups were 41.7% and 47.6% from liver, 33.3% and 47.6% from spleen and 8.3% and 14.3% from cecum, respectively, and the SE nonisolated and the SE seronegative group were 63.6% and 64.7% from liver, 84.1% and 88.2% from spleen and 47.7% and 52.9% from cecum. The serological response of the SE isolated and the SE seropositive groups hardly changed from 75.0 and 81.8% before challenge to 75.0 and 85.7% after. But, the other two groups were found to be significantly higher after challenge and increased from 0 and 18.2% to 100%. Consequently, S. enteritidis preinfected chickens were found to be significant different in terms of mortality, weight gain, reisolation of S. gallinarum and serological response compared to noninfected chickens. Moreover, our study shows that S. enteritidis infected chickens appear strong competitive exclusion against the colonization of S. gallinarum.

OBJECTIVE: This study was aimed to investigate of newborn babies sex ratio in Seoul Seong Ae hospital and review of future problem. METHODS: We reviewed retrospectively the 21,332 cases of deliveries in women visiting at Seoul Seong Ae hospital from Jannuary 1994 to December 2003 (10 year's period). We investigated 1st baby and 2nd baby sex ratio and in case of 3rd baby, subdividing then into tree groups (first and second are female, first and second are male, first and second are male and female). We arranged the data at the base of childbirth registers and patients' obligation records. RESULTS: The results were as follows, 1. The total sex ratio in last 10 years was 111.2:100 (male:female). 2. 1st baby sex ratio was 109.2:100. 3. 2nd baby sex ratio was 110.6:100. 4. 3rd baby sex ratio was 133:100. CONCLUSION: These findings suggest that unbalance of sex ratio in 3rd baby is extremely serious trend in this country and is expected a tremendous social problems in early 21th century.

To our knowledge, only one case of vaginal cavernous hemangioma in pregnancy has been reported all over the world and there is no report in Korea. The authors have experienced one case of vaginal cavernous hemangioma in pregnancy and report our case with a brief review of literature.

To our knowledge, implantation into the uterine muscle wall is one of the rare form of ectopic pregnancy, with only 16 cases reported until 1995. The early diagnosis depends upon the sonographic finding of intramural gestational sac-like growth and persistent high beta human chorionic gonadotropin (beta-hCG) levels after dilatation and curettage. But, nobody can't exclude intramural pregnancy in case that associated with adenomyosis in uterus in spite of negative beta-hCG. Hsieh et al. and Dousias et al. mentioned 2 cases of such situation with negative beta-hCG result. And confirmative diagnosis depends upon the pathologic finding for specimen obtained from laparoscopic or explorative hysterotomy. The authors have experienced one case of intramural pregnancy in uterus and report our case with a brief review of literature.

A 3-month-old female presented with anuria and abdominal distention for 1 day. The patient was twin and was delivered at 30 week-term with low birth weight. Emergent ultrasonography revealed both hydronephrosis and hyperechogenic mass within the both renal pelves. Urinoma around left kidney was also found. Computed tomography showed high density material filled dilated pelvises. Urinoma measured 3x4cm in the left prerenal space and urinary ascites in the right abdomen were found. Candida albicans was cultured from catheter drained urine. We started the care with percutaneous nephrostomy with amphotericin B irrigation, coupled with systemic antifungal therapy. And this management had a major role in the successful outcome.

This study aimed to investigate the frequent intraoperative and postoperative complications and visual outcome of phacoemulsification or extracapsular cataract extraction after vitrectomy. The authors reviewed the medical records of 30 paitients who had undergone pars palana vitrectomy and followed by cataract extraction from January, 1996 to January, 1998, and had been followed up for 3 months or longer. Associated retinal diseases included complication of diabetic retinopathy (11 cases,36.7%), vitreous hemorrhage from branch retinal vein occlusion (6 cases, 20.0%), proliferative vitreoretinopathy (4 cases,13.3%). Mean interval between two operations was 21.0 months. The most commom intraoperative complication was anterior chamber depth fluctuation (4 cases).In a few cases,we had radial tear (3 cases) in lens capsule or miosis (2 cases). The most common early postoperative complication was corneal edema and late complication was posterior capsular opacity.Postoperative visual acuity remained still or improved in 28 cases (93.37%) at postoperative 3 months. In conclusion cataract extraction after vitrectomy may be performed safely with few complications. Visual outcome was favarable but was mainly dependent on previous vitreoretinal patholgy.

Apert syndrome is an uncommon congenital disorder characterized by malformation of the skull in association with symmetrical syndactyly of both hands and feet. This syndrome is autosornal dominant. The original description was presented by Apert in 1906. Since then more than 200 cases have been reported in the world. Recently, we experienced a case of newhorn male infant with congenital anomalies of the skull and extremities. Molecular biologically, he was found to have Ser252Try mutation in the FGFR2 exonIIIa. A brief review of literature was made.

Hydrogen peroxide has been used for various medical purposes and also recommended in the disinfection process for endoscopes. However, hydrogen peroxide as a cause of chemical colitis or disinfectant colitis has been infrequently reported. The endoscopic findings of hydrogen peroxide induced colitis revealed pseudomembranous-like enteritis such as white plaques, erythema, foamy liquid, patchy, granularity, and ulcerations, resulting from effervescence caused by the release of oxygen from the breakdown of hydrogen peroxide. A 36 year-old single male, who had 30 ml of 3% hydrogen peroxide inserted into his anus the day before due to sexual reasons, was hospitalized as a result of suffering from hematochezia, tenesmus, and lower abdominal pain. Colonoscopy revealed discrete or confluent white plaques adherent to the colonic mucosa, severe erythema on the surrounding mucosa, patchy granularity, and scattered ulcerations up to 28 cm from the anal verge. Pathologic finding revealed inflammatory cells infiltration, variable sized vacuoles, vascular congestion, hemorrhage, fibrin deposition and ulcerations with regenerating epithelium in the lamina propria, consistent with acute mucosal injury caused by hydrogen peroxide. A case of hydrogen peroxide induced colitis is herein reported.
