Malignant cells in culture express elevated levels of transforming growth factor-beta1 (TGF-beta1) mRNA and secrete an abundant amount of the TGF-beta1 protein. An attempt was made to define the role of the TGF-beta1 secreted from tumor cells, as a possible humoral factor which functions in a paracrine manner to stimulate the production of collagen and angiogenesis in gastric carcinoma. The expression of the TGF-beta1 by immunohistochemical stain (n=70) in gastric adenocarcinoma tissues was studied. Angiogenesis was evaluated by immunohistochemical staining of tumor vessels, using polyclonal antibody to factor VIII related antigen and counting the three most active areas of neovascularization. The extracellular matrix was counted as area density by using an image analyzer following Masson-Trichrome staining. The prominent reactivity for TGF-beta1 was associated with invasion depth (r=0.2, p<0.05), increased number of microvessel (r=0.49, p<0.05) and increased area density of extracellular matrix (r=0.36, p<0.05), respectively. In summary, TGF-beta1 may have a role in tumor invasion and metastasis by increased angiogenesis and deposits of extracellular matrix.

OBJECTIVE: The conventional methods to determine fetal genetic status, such as amniocentesis or chorionic villi sampling(CVS) have small procedure-related risk of abortion. Recently, several researchers reported that fetal genetic status, such as sex, can be confirmed by fetal nucleated erythrocytes in maternal blood and this method might reduce such risk. Therefore, in this study, we attempted to determine the basic fetal genetic status, sex, with fetal nucleated erythrocytes. METHODS: In twelve pregnant women who undertook amniocentesis or CVS, 20 ml of venous blood was drawn immediately before the procedure and the nucleated erythrocytes were recovered by magnetic activated cell sorting(MACS). After MACS, DNA was extracted from 200 microliter of sample and single nucleated erythrocyte was obtained by additional procedure, immunostaining, and microdissection. After recovery of nucleated erythrocytes by microdissection, nested polymerase chain reaction(PCR) and fluorescent PCR of amelogenin gene were performed to identify the fetal gender. RESULTS: The DNA of enriched erythrocytes after MACS could identify the fetal gender in the 58.3% of the samples by nested PCR. After the recovery of single nucleated erythrocyte by MACS, immunostaining and microdissection, the minute DNA in a single cell could be amplified by primer extension preamplification(PEP), nested PCR, and fluorescent PCR. Fetal genders were correctly identified in 8 out of 12 (66.7 %). CONCLUSION: Through this study, we could conclude that fetal nucleated erythrocytes in maternal blood might be sufficient sample to determine fetal sex. And single cell isolation by microdissection could get the better results than nested PCR after MACS only. However, in spite of the pregnancy of male fetus, female specific bands were obtained after nested PCR of amelogenin in several cells, which might suggest that part of nucleated erythrocytes in maternal blood might be maternal origin. Therefore, to determine fetal genetic condition by nucleated erythrocytes in maternal blood, further improvements of methods to identify the nucleated erythrocytes of fetal origin are needed.

Mutations in the p53 gene occur during the development of colorectal carcinomas, and play an important role in the conversion of adenoma into carcinoma. To detect the p53 gene mutation and its pattern of expression in colorectal carcinomas, polymerase chain reaction for exons 5, 6, 7, and 8, recombinant gene cloning, and automated DNA sequencing were performed with 30 fresh colorectal carcinomas. Each tissue was also analyzed by immunohistochemical staining for p53 protein. p53 protein was detected in 25 of 30 (83.3%) colorectal carcinomas by immunohistochemical study. p53 mutation was detected in 4 of 30 (13.3%) colorectal carcinomas. The distribution of these mutations among these exons investigated was as follows: Three mutations in exon 5 (66.7%) and 1 mutation in exon 7 (33.3%). One case with mutation in exon 5 had mutations at three different codons. Mutations in exon 5 were found at codon 153 (GGG to AGG: Gly to Arg), 170 (TGC to GGC: Cys to Gly), 186 (CTA to TTA: silent mutation), 158 (GCG to ACG: Ala to Thr), and 176 (ACG to ATG: Thr to Met). Mutation in exon 7 was found at codon 248 (AGG to AGA: silent mutation). Four of them were missense mutations. Two of 6 mutations were silent mutations. Five transition mutations and 1 transversion mutation were also detected. All cases with mutations by automated DNA sequencing showed positive p53 protein immunohistochemical stainining. In conclusion, p53 gene mutation was detected in 4 of 30 (13.3%) colorectal carcinomas, located in codon 153, 158, 170, 176, and 186 of exon 5 and codon 248 of exon 7. Further studies are needed to evaluate the significance of the codon 153 mutation which was not recognized in other studies on colorectal carcinomas.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

Conjoined twins occur when there is imcomplete fission of the inner cell mass later at approximately 13 to 15 days after fertilization. The earlist case in the literat.ure appears to be that of the Biddenden Maids who were born in England in 1100. since then over two hundred cases of successful separation were reported on literature. And also successful separation cases were reported by Seung et al.(1991) in Korea. Conjoined twins occur between one in 50,000 to 100,000 births but real incidence is one in 200,000 because two thirds are stillbirth or died immediately after birth. The conjoined twins are not associated with maternal age, race or family history and 70 % of them are females. We experienced a case of conjoined twins with omphalopagus and performed surgical separation. A brief review of related literatures was done.
