BACKGROUND: To clarify the clinical significance of CEA and CA19-9 in patients with gastric cancer, we evaluated the correlation between tissue expression, the peripheral and the portal levels of these tumor markers, and ten clinicopathological factors, as well as the prognosis. METHODS: Surgical specimens from 40 patients with gastric cancer were examined by using immunohistochemical staining with anti-CEA and anti-CA19-9 monoclonal antibodies. Serum levels of CEA and CA19-9 in the portal and the peripheral blood were measured by using immunoradiometric assays. RESULTS: Positive values of the portal venous CEA were more common in patients with lymph-node metastasis, distant metastasis, and lymphatic invasion than in those without these factors. Curative surgery was performed in 50.5% of the patients with high portal CEA levels and in 90.6% of the patients with low portal CEA levels. Positive values of the peripheral venous CEA were significantly higher in cases with lymph-node metastasis. The positive rate of CA19-9 immunohistochemistry was significantly higher in patients with distant metastasis and in non-curative surgery. The positive rate of peripheral venous CA19-9 was higher in cases with distant metastasis. The three-year survival rate of patients with negative tissue CEA was significantly higher than that of patients with a positive result. The peripheral venous levels of CEA and CA19-9 reflected the portal venous levels accurately. CONCLUSIONS: These results suggest that immunohistochemical examination of CEA in patients with gastric cancer is useful for the evaluation of the biological aggressiveness and progression of the disease and can be used for making a prognosis.

Most mammalian embryos implant on the uterine endometrium after hatching fromzona pellucida of the expanded blastocyst and pregnancy takes place. The blastocysts produceand control a variety of prostaglandins which activate a few proteolytic enzymes thatdissolve the zona pellucida of the embryos. In the present study, the goal was to investigatethe indomethacin and aspirin(inhibitors of cyclooxygenase pathway which regulates thepathway from arachidonic acid to prostaglandins), which can affect the hatching and implantationof the mouse embryos by the treatment of the different dose level of indomethacinand aspirin in the culture of mouse embryos.The female and male ICR mice, 6~8 weeks and were used for superovulation andmating and M16 was used as a basic culture medium.The above results can be summarized as following:1. Indomethacin seemed to inhibit the development of the mouse embryos and hatchingprocess because of inhibiting or blocking the activation of hatching related enzymes andhigh dose of indomethacin inhibited implantation.2. Aspirin had no effect on the hatching of the embryos at the dose of 0.16 mg/ml.3. FBS seemed to contain a factor which induced outgrowth of the embryo whereasBSA did not and outgrowth did not take place in the BSA contained medium.4. Blastocysts produced enough prostaglandins F2alpha which was needed for thehatching whereas they needed a factor for implantation which might be produced in theendometrium or exuded from the blood.In conclusion the concentration of indomethacin used in the present study inhibithatching of the blastocysts. This seems to be caused by inhibiting the synthesis of theproteins need for hatching. The factor that induce the outgrowth of the blastocysts doesnot seem to be produced in the blastocysts themselves but seem to be present in the FBS.

Heterotopic pregnancy, simultaneous intrauterine and extrauterine pregnancy, is an extremely rare case. The incidence of heterotopic pregnancy was about 1 to 30,000 pregnancies, but it has increased after wider use of assisted reproductive technology. The rising incidence presents a serious problem as the diagnosis of this potentially fatal condition is often missed. Careful pelvic examination combined with serial beta-hCG determinations, and transvaginal sonography to evaluate the adnexal region are necessary prerequisites for early diagnosis. We report a case of heterotopic pregnancy following in vitro fertilization and embryo transfer(IVF-ET) with a brief review of literature.

Factor VII deficiency is a rare, inherited coagulopathy, which can lead to prolonged bleeding. Here, we present a case report of an adolescent with factor VII deficiency who experienced small bowel bleeding that was successfully treated with tranexamic acid. This case highlights the potential use of tranexamic acid as an effective therapeutic option for managing gastrointestinal bleeding in patients with hemostatic insufficiency of unknown etiology.

From May, 1975 to August, 1986, we experienced 21 patients with ruptured aneurysm of the sinus of Valsalva. 1) Their ages ranged from 15 to 52 years with a mean age of 26.7 years, and 14 patients were male and 7 patients were female. Among 18 cases of which aneurysms occurred on the right sinus of Valsalva, 15 cases (83%) ruptured into the right ventricle, 1 case (6%) ruptured into the right atrium and 2 cases (11%) ruptured into the pulmonary artery. All 3 cases of which aneurysms occurred on the noncoronary sinus ruptured into the right atrium. 2) Clinical symptoms consisted of dyspnea (95%), palpitation (81%), chest pain (43%), orthopnea (33%), cough (14%), hemoptysis (5%), oliguria (5%), and fever (5%). In all patients continuous heart murmur was audible. Hepatomegaly (48%), pulmonary basal rale (14%), and pretibial pitting edema (19%) were also observed. 3) In all patients diagnosis was made with cardiac catheterization and angiography, and confirmed by operation excetpt one case. 4) Among 20 patients who had been performed corrective surgery, ventricular septal defect was observed in 16 patients (85%), aortic insufficiency in 5 patients (25%), pulmonary infundibular stenosis in 1 patient (5%), patent foramen ovale in 1 patient (5%), and tricuspid insufficiency in 1 patient (5%). Ventricular septal defect was observed in all 16 patients whose aneurysms of the right coronary sinus of Valsalva ruptured into the right ventricle and the pulmonary artery. 5) All patients survived operation, and no postoperative complication was found except 1 patient to whom reoperation was performed because of postoperative aortic insufficiency and detachment of the patch closure for ventricular septal defect. There was symptomatic improvement in all patients.

In order to investigate the role of adenovirus in diarrheal children, we evaluated 907 children with diarrhea and 193 children without diarrhea for a 22-month. Stools were tested for group A rotavirus antigen and for adenovirus types 40/41 (Ad 40/41) by using ELISA, cell technique and indirect immunofluorescent method. Adenovirus was detected in 10.1% of the diarrheal children and 3.1% of the non-diarrheal children. Ad40/41 was detected in 4.85% of the diarrheal children. Other nonenteric adenovirus was detected in 5.29% of the diarrheal children. In addition, 24% of the adenovirusinfected children excreted rotavirus simultaneously. Rotavirus was found in 57.1% of the diarrheal patients. Among the diarrheal children. 88% of those with adenovirus were younger than 24 months. Although peaks of adenovirus infection were detected in July and Autumn in the study, there is no apparent seasonal trend with adenovirus. The average duration of admission caused by adenoviral infection was 4.9 days and 88% of the cases accompanied by fever. Stool occult blood test revealed positive reaction in 66.3% of the cases and serum aminotransferase activities transiently elevated in 5.4% of the cases. Diarrhea with more than 10 stools per day, vomiting, or fever in adenovirusinfected children were similar with ratavirus, where as the first two manifestions were associated with confection of rotavirus and adenovirus. Nine out of 92 cases(9.8%) of the gastroenteritis caused by adenovirus revealed intussusception. We conclude that Ad40/41 is an important cause of diarrhea among infants and children, and non-enteric adenovirus is considered to be a cause of diarrhea, but their role in diarrheal children should be further studied.
