概要: 金沢大学医薬保健研究域医学系<br />Histone acetylation and deacetylation have been thought to be related to gene expression, and there are many reports indicating that histone deacetylase inhibitors (HDACis) exert antifibrogenic effects in several organs. In injured livers, hepatic stellate cells (HSCs) are activated in response to profibrogenic mediators and produce large amounts of extracellular matrix. In particular, transforming growth factor-β1 (TGF-β1) is considered as a key factor in accelerating hepatic fibrosis because it is released from activated HSCs and further stimulates them. The present study aimed to clarify whether sodium valproate (VPA) has suppressive effects on cultured human HSCs (LI90). We showed that treatment with VPA had no significantly suppressive effect on cell proliferation at a concentration of 1 mM, which corresponded approximately to the serum concentration obtained by the administration of a clinical dose. However, VPA prevented the morphological changes characteristic for activation and inhibited the expression of collagen type 1 α1 (COL1A1) and TGF-β1 in activated LI90 cells at the mRNA and protein levels. Our results support the hypothesis that VPA exerts antifibrogenic activity with little cytotoxicity at 1 mM, and HDACis are expected to be used in clinical practice for the treatment of fibrotic diseases.<br />Embargo Period 6 months 続きを見る

概要: 金沢大学医学部附属病院肝胆膵・移植外科 <br />Background/Purpose: Management of the pancreatic remnant after distal pancreatectomy is still debated, the most serious complication is development of a pancreatic fistula. We developed a nonclosure technique with saline-coupled bipolar electrocautery for preventing fistula formation after distal pancreatectomy as an alternative to traditional stump closure methods. Methods: The distinguishing feature of this technique is nonclosure of the stump, relying instead upon dependable ligation of the main pancreatic duct and sealing of the cut surface by shrinkage accomplished by low-temperature coagulation using saline-coupled bipolar electrocautery. A recent addition has been intraoperative stenting of the remnant pancreatic duct. Results: To date we have used the nonclosure technique in 40 cases, among which 5 (12.5%) developed fistulas: 4 in the nonstenting subgroup (14.8%) and 1 in the stenting subgroup (7.7%). According to a recent classification, 4 fistulas were considered grade A; 1, grade B; and 0, grade C. The grade B patient did not undergo stenting. Conclusion: Our preliminary experience should prompt more widespread evaluation of the nonclosure technique. © Springer Japan 2008. 続きを見る

概要: 金沢大学医学部附属病院肝胆膵・移植外科 <br />In patients with carcinoma of the head of the pancreas with positive lymph nodes, the extent o f an adequate lymph node dissection beyond peripancreatic area has remained controversial. Based on the two anlagens, the ventral or dorsal pancreas, we assessed the lymphatic spread pattern in 58 primary adenocarcinoma of head of the pancreas. Detection of lymph node mestastasis was based on microscopic detection of carcinoma in consecutive serial sections of resected specimens including lymph nodes. When the tumor was confined to the ventral pancreas domain (n=20), the lymph node metastases were limited to areas along the superior mesenteric artery (SMA) besides peripancreatic lymph nodes. When the tumor was in the dorsal pancreas domain (n=6), the lymph node metastases were limited to areas along the common hepatic artery (CHA) and the hepatoduodenal ligament besides peripancreatic lymph nodes. When the tumor was extended into both domains (n=32), the lymph node metastases were distributed widely in areas along the SMA, CHA and the hepatoduodenal ligament besides peripancreatic lymph nodes. Based on these findings, the lymphatic spread of carcinomas of the head of the pancreas can be divided into two patterns by tumor location based on the two anlagens of the pancreas. 続きを見る
