Recent advance in the field of microvacular surgery has popularized the reattachment of severed digit, with increasing success rate and improving functional regain. Reattachment surgery was performed in six digits, two thumbs and four fingers, which had been amputated at or distal to the level of DIP joint. Microvascular anastomosis of one digital artery was done and the venous drainage was reestablished with blood letting from the pulp of each digit. There was one failure in which hypersensitivity to heparin was present, while all other five showed success. Postoperatively considerable sensory recovery was present in all.

Sixty one cases of gastric adenocarcinoma were studied immunohistochemically for expression of HLA-DR and secretory component(SC) in order to analyze the relationship between expression of these in gastric cancer cells and the adjacent mucosa. Immunostaining was detected within the cytoplasm and on the cell memgrane. The rate of HLA-DR and SC expressions in cancer cells were 59.0% and 49.2%, respectively, and 52.5%/52.5% and 31.2%/50.8% the mucosa in adjacent/remote from the site of to cancer. The SC expression in the adjacent mucosa was lower than that of the remote mucosa(p=0.027). The HLA-DR expression in the cancer cells in the intestinal type of gastric adenocarcinoma(73.9%) was higher than that of the diffuse type(14.3%) and it was statistically significant(p=0.02). The presence of an increased amount of lymphoid infiltration in the gastric mucosa was closely related to the expression of HLA-DR and SC. Decreased or absent expression of SC at the transitional mucosal cells was possibly a result of exposure to genotoxic agents due to the lack of protective function of SC-IgA. From these results, one can postulate that the expression of HLA-DR and SC may play an important role in atleration in microenvironment with lymphoid infiltration.

PURPOSE: p53 gene mutations, one of the most common alterations found in human tumors, has also been detected in gastric carcinoma, and shown to have a crucial and early role in gastric carcinogenesis of intestinal type and mainly associated with tumor progression in the cancer of diffuse type. We tried to investigate the frequency of p53 mutations in 27 gastric carcinomas. MATERIALS AND METHODS: Fresh tumor tissue from a series of gastric carcinoma was screened for p53 mutations by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) with silver staining and confirmed by direct-sequencing in 27 cases of gastric carcinoma. Immunohistochemical method for p53 protein accumulation was also performed in the same cases. RESULTS: Immunohistochemistry revealed 20 of 27 cases of gastric carcinoma, positive for p53. PCR-SSCP analysis of p53 exons 5-8 detected mobility shift in 4 out of 20 p53-positive tumors; three from exon 5 and the other from exon 7, respectively. DNA sequencing of exon 5 showed CGC to CAC point mutation in one of three cases; exon 7, ATC to AAC point mutation. It seemed that there was no correlation between genetic alterations of p53 gene detected by PCR-SSCP and expression of p53 protein by immunohistochemistry. CONCLUSIOAS: Our results suggest that mutations of the p53 gene are rare genetic events in carcinogenesis of gastric carcinomas. There was discrepancy between mutations screened by PCR-SSCP and overexpressions in immunohistochemical staining.
