To compare the efficiency, success rate and abortion time of applications of intravaginal misoprostol versus intravenous Sulprostone(Nalador) for mid-trimester pregnancy termination. Eighty three patients between 17-29 weeks of gestation with medical, obstetric, or genetic reasons for termination of pregnancy were randomized to receive either 50 ug tablets of misoprostol placed in the posterior vaginal fomix or 1,000ug sulprostone intravenously diluted I L of isotonic saline solution given as a 12-h infusion. Among eighty three patients recruited, fourty five patients received misoprostol and thirty eight patients received sulprostone intravenously. The average interval from start of induction to vaginal delivery was 13.35+/-3.34 hours in misoprostol group and 21.14+/-6.64 hours in the sulprostone group. The success rate of complete termination within 12 and 24 hours in misoprostol group were 57.7%, 93.3%, respectively, while in sulprostone group were 15.8%, 92.1% respectively. Oxytocin augumentation was 6.7% in misoprostol group and 7.9% in the sulprostone group. No serious complication occurred. Intravaginal misoprostol appears to be acceptably safe and effective agents for second trimester pregnancy termination. Misoprostol has the advantage of being inexpensive, easily stored and readily available. The regimen of 100 ug misoprostol inserted intracervicovaginally every 8 hours is the optimal method for pregnancy termination.

Angiogenesis is a crucial step in tumor growth and progression. Scarce data is available on angiogensis in gastrointestinal tumors. We studied 16 normal colon, 44 adenomas and 29 carcinomas to evaluate angiogenesis in colorectal tumors and to assess the correlation among p53 protein, proliferative activity and other clinical prognostic parameters. Endothelial cells were immunostained with an anti-Factor VIII mAb; in each case three microscopic fields(x 200) were counted: average number of the three fields was defined as microvessel density (MVD). p53 protein expression was 45.5%(20/44) in adenomas, and 79.3%(23/29) in carcinomas (p<0.01). p53 protein expression of carcinomas was 57.1%(4/7) in diploid tumors, 100%(8/8) in aneuploid tumors (p=0.07), 100%(8/8) in well differentiated tumors, and 50%(2/4) in poorly differentiated tumors (p=0.09). MIB-1 score was 2.3+/-0.7(38) in adenomas, 3.4+/-0.5(29) in carcinomas (p<0.01). There was no significant correlation between p53 protein and MIB-1 score. MVD was 10.4+/-4.1(16) in the normal mucosa, 21.5+/-7.9(39) in the adenomas, 35.3+/-9.7(26) in carcinomas (normal versus adenomas, p<0.01; adenomas versus carcinomas, p<0.01). MVD was 25.8+/-5.4(2) in carcinomas confined to mucosa, and 36.1+/-9.6(24) in carcinomas with transmural invasion. The higher MIB-1 score was in carcinomas the more MVD increased but there was no statistical significance (r=0.38, p=0.055). MVD of carcinomas was not associated with nodal metastasis, p53 expression, and DNA ploidy. p53 protein and MIB-1 expression are useful methods for the evaluation of malignancy, and tumor angiogenesis is an early event in a colorectal tumor but MVD does not correlate with prognostic parameters except for the tumor depth.

Heat shock protein 70 (HSP70) is a chaperone that binds to mutant p53 and consequently can regulate its accumulation or localization. Its expression is upregulated in tumor cells. We studied 44 adenomas and 29 carcinomas of colorectum to evaluate the expression of HSP70, and to assess the correlation among p53 protein and other clinical prognostic parameters. HSP70 expression was scored according to staining intensity and extent. p53 protein expression was 45.5%(20/44) in adenomas and 79.3%(23/29) in carcinomas(P<0.01). p53 protein expression of carcinomas was 57.1%(4/7) in diploidy tumors, 100.0%(8/8) in aneuploidy tumors(P=0.07), 100.0%(8/8) in well-differentiated tumors, and 50.0%(2/4) in poorly differentiated tumors(P= 0.09). HSP70 expression mainly revealed a fine granular cytoplasmic staining pattern in tumor cells. HSP70 was focally detected in some lymphocyte, ganglion cell and normal mucosa. HSP70 expression was 46.3%(19/41) in adenomas and 93.1%(27/29) in carcinomas. HSP70 score was 0.9+/-1.3 in adenomas(n=41) and 5.5+/-3.5 in carcinomas(n=29)(P<0.0005). Its score was 1.7+/-1.6 in p53 positive adenomas and 0.3+/-0.6 in p53 negative adenomas(P<0.005), and its expression rate was higher in p53 positive carcinomas than p53 negative carcinomas (P>0.05). There was no significant correlation among HSP70, tumor size, Dukes'stage, nodal metastasis, depth of tumor invasion, DNA ploidy and tumor differentiation. In conclusion, HSP70 and p53 protein appear to be correlated to each other, and that HSP70 and p53 protein may play a certain role in the progression of colorectal tumor. Further studies are needed for determining their prognostic factors in colorectal carcinoma.

Intestinal metaplasia (IM) have long been thought to play a role in the pathogenesis of gastric intestinal adenocarcinoma, but not in that of diffuse cancer. We studied 20 normal gastric mucosa, 90 IM, 39 atypia (dysplasia or adenoma), and 51 adenocarcinoma to evaluate the expression of p53, erb B2, and H-ras p21 proteins and to assess the correlation with IM (esp. type III IM, revealing positive HID-AB/PAS for sulfomucin). Positive rate of HID-AB staining revealed an increased trend in comparison between IM, atypia and adenocarcinoma. It was the highest in mucinous carcinoma, but it was not correlated with positive oncoprotein expressions. Positive rates of oncoproteins revealed increased trends in comparison between IM, dysplasia or adenoma and adenocarcinoma in c-erb B2 and p53 (P<0.01). The positive rates were highest in intestinal adenocarcinoma (50.0% and 54.2%, respectively). Rates were lowest in biopsy tissue of IM (4.4% and 8.7%, respectively). The expression of H-ras p21 was not significant in gastric carcinogenesis. There was no significant correlation between oncoproteins and other clinical parameters, such as depth of invasion, differentiation, size and nodal metastasis of the tumors. Therefore, we suggest that p53 and erb B2 may play a role in the carcinogenesis of gastric intestinal adenocarcinoma.

Fulminant hepatic failure (FHF) is often accompanied by a myriad of neurologic complications, which are associated with high morbidity and mortality. Although appropriate neuromonitoring is recommended for early diagnosis and to minimize secondary brain injury, individuals with FHF usually have a high chance of coagulopathy, which limits the ability to use invasive neuromonitoring. Jugular bulb venous oxygen saturation (JvO₂) monitoring is well known as a surrogate direct measures of global brain oxygen use. We report the case of a patient with increased intracranial pressure due to FHF, in which JvO₂ was used for appropriate brain oxygen monitoring.

Spontaneous perforation of bile duct in adults is very rare, with less than 30 cases described in the literature to date. We repoit a case of a 65-year-old man who presented with severe colicky abdominal pain and fever, just like symptoms of peritonitis. ERCP provided a preoperative noninvasive confirmation of the diagnosis of the rupture of right intrahepatic duct. The patient was performed T-tube choledochotomy and drainage of retroperitoneal bile collection. The etiolgy, diagnosis, and treatment of spontaneous perforation of bile duct is discussed.
