We examined the intracellular distribution of 8-oxo-dGTPase (8-oxo-7,8-dihydrodeoxyguanosine triphosphatase) encoded by the MTH1 gene, a human mutator homologue. The activity of 8-oxo-dGTPase mainly located in cytosolic and mitochondrial soluble fractions of Jurkat cells, a human T-cell leukemia line. Electron microscopic immunocytochemistry, using a(More)
In this study, the ability of granulocyte colony-stimulating factor (G-CSF) to treat or prevent chemotherapy-induced oral mucositis in patients with advanced breast cancer was evaluated. A total of 14 patients who received intra-arterial (i.a.) adriamycin (ADM) preoperatively were divided into two groups according to whether or not G-CSF was given. Thus,(More)
The use of laparoscopic splenectomy has increased in recent years, primarily for patients with idiopathic thrombocytopenic purpura (ITP). We describe herein the first known case of a laparoscopic splenectomy to be performed in Japan for a patient with a giant splenic epidermoid cyst. A 26-year-old woman presented to our hospital with the major complaint of(More)
We report a rare case of secondary involvement of the gallbladder by metastatic renal cell carcinoma. A 71-year-old man was diagnosed as having a polypoid mass within the gallbladder when he underwent right nephrectomy for a renal cell carcinoma. A preoperative diagnosis of simultaneous carcinoma of the gallbladder was made, and extended cholecystectomy(More)
cDNA encoding rabbit O6-methylguanine-DNA methyltransferase that repairs DNA damaged by alkylating agents was isolated, using as a probe a fragment of mouse cDNA coding for a region containing the active site of the enzyme. The nucleotide sequence of the cDNA revealed that the rabbit methyltransferase is a 181-amino acid polypeptide with a mol. wt of(More)
