Abstract
A 77-year-old man with complaining of anemia and abdominal pain was admitted to our hospital. An abdominal computed tomography showed the sigmoid colon tumor with bowel obstruction. Laparoscopic transverse colostomy was performed to release intestinal obstruction. After first operation, he was diagnosed the sigmoid colon cancer: cT4b(bladder), cN0, cM0, and cStage Ⅱc. Radical laparoscopic operation(Hartmann's operation)was performed. On the 4th postoperative day, fecal juice was discharged from the abdominal drain placed in the Douglas fossa, so emergency laparotomy was performed. The intraoperative findings showed perforation in the blind end of the descending colon. The descending colon was resected from a site approximately 5 cm anal side of the transverse colostomy to the blind end. It was thought that perforation occurred due to an increase in internal pressure in the residual intestinal tract after Hartmann's surgery without blood flow disorder. We believe that further attention is required to the management of residual intestinal tract at the blind end for the obstructive colorectal cancer.

Abstract
A 56-year-old woman complaining of right lower abdominal pain was admitted to our hospital. An abdominal computed tomography showed the enlarged appendix tip and a high density area around the appendix to retroperitoneum. The patient was diagnosis with acute appendicitis and underwent emergency laparoscopic appendectomy. Histopathological findings of the resected specimens revealed a component with signet ring cell carcinoma morphology that was positive for neuroendocrine markers by immunohistochemical staining, which led to the diagnosis of goblet cell carcinoid(GCC)of appendix. GCC cells were found to infiltrate the surrounding serosa and Ly positive. An additional laparoscopic ileocecal resection with D3 dissection was performed. In the appendix GCC, additional resection is considered because the lymph node metastasis rate increases(SS/13%)as the depth of wall progresses. Appendiceal tumors including GCC may develop acute appendicitis and may be followed by additional resection. Therefore, it is important to consider how to deal with the first surgery.

Abstract
Fatty acid synthesis in pea chloroplasts is regulated by light/dark. The regulatory enzyme acetyl-CoA carboxylase is modulated by light/dark, presumably under redox regulation. Acetyl-CoA carboxylase is a multienzyme complex composed of biotin carboxylase and carboxyltransferase (CT). To demonstrate the redox regulation of CT, composed of the nuclear-encoded alpha and the chloroplast-encoded beta subunits, we identified the cysteine residues involved in such regulation. We expressed the recombinant CT in Escherichia coli and found that the partly deleted CT was, like the full-length CT, sensitive to a redox state. Site-directed mutagenesis of the deleted CT showed that replacement by alanine of the cysteine residue 267 in the alpha polypeptide or 442 in the beta polypeptide resulted in redox-insensitive CT and broke the intermolecular disulfide bond between the alpha and beta polypeptides. Similar results were confirmed in the full-length CT. These results indicate that the two cysteines in recombinant CT are involved in redox regulation by intermolecular disulfide-dithiol exchange between the alpha and beta subunits. Immunoblots of extract from plants incubated in the light or dark supported that such a disulfide-dithiol exchange is relevant in vivo. A covalent bond between a nuclear-encoded polypeptide and a chloroplast-encoded polypeptide probably regulates the enzyme activity in response to light.

Abstract
We report the case of a 51-year-old female with stage IV advanced breast cancer accompanied by multiple bone metastases. A hard mass of about 3.0 cm in diameter was palpated just below the nipple. An excisional biopsy was performed and histological examination revealed infiltrated solid tubular adenocarcinoma. There were no estrogen or progesterone receptors in the tumor. Modified radical mastectomy was performed in October, 1998. Postoperative adjuvant therapy with 10 cycles of CEF therapy was undertaken for one year. Combined chemoendocrine therapy with 5'-DFUR and MPA was also conducted for 11 months. Bone scintigraphy showed that all bone metastatic lesions disappeared completely one year after the operation. Mild bone marrow suppression, alopecia and body weight gain were observed as side effects. It is suggested that this combination therapy may be useful for advanced breast cancer patients with multiple bone metastases.

Abstract
Restriction landmark cDNA scanning (RLCS) is a novel method by which more than 1000 genes can be simultaneously and quantitatively displayed as two-dimensional gel spots. Here we present an adaptation that allows an individual spot to correspond to a unique gene species without redundancy in more than two gel patterns. Using this improved RLCS, we examined global changes on the gene expression of PC12 cells before and after treatment with nerve growth factor. Among a total of 3000 spots, 21 (0.70%) and 91 (3.03%) spots newly appeared and became more intense with treatment. On the other hand, 15 (0.50%) and 44 (1.47%) spots disappeared, becoming less intense with treatment. These observations suggest that approx. 6% of the detected PC12 genes are up-(3.73%) or down-(1.97%) regulated when the cells differentiate to neuronal cells. In comparison with the results obtained using the expressed-sequence-tag approach, previously reported by Lee et al. (Proc. Natl. Acad. Sci. USA 92 (1995) 8303-8307), RLCS should be useful for quantitatively examining the global change of differentially expressed genes of various expression levels.

Abstract
Three cases of percutaneous retrieval of foreign bodies that migrated into the pulmonary artery are described in this paper. All of the intravascular foreign bodies were attributed to SVC catheters for intravenous hyperalimentation (IVH) therapy, an accidentally cut strip of indwelling SVC catheter in two patients and a fragment of guide wire used for the insertion of the SVC catheter in one patient. They were all successfully removed by fluoroscopic angiographic procedures using a snare loop retriever and grasping forceps. The technical aspects of the procedures are discussed here.

Abstract
To investigate the mechanism of glucose intolerance in patients with Graves' disease, a 2-hour oral glucose tolerance test and euglycemic glucose clamp study using Biostator were performed in patients with Graves' disease and control subjects. 80 per cent of the patients showed impaired glucose tolerance. Insulinogenic index in the patients with borderline or diabetic glucose response was lower than that in subjects with normal glucose response. Insulinogenic index was inversely correlated with sigma PG during the test. Despite normal basal plasma glucose concentrations, basal plasma insulin levels in the patients with Graves' disease were higher than in the controls. Using the euglycemic glucose clamp technique, the glucose utilization rate (M value), the metabolic clearance rate of glucose (MCRG) and the insulin sensitivity index (M/I x 100) in the patients with Graves' disease were lower than in the controls. After treatment with antithyroid drug in 3 patients, glucose tolerance completely normalized, and there was a significant increase in the M value and the MCRG and a significant decrease in the metabolic clearance rate of insulin (MCRI) compared to the values before treatment. In the patients with Graves' disease, basal serum glucagon levels were higher than in the controls, and glucagon suppression during insulin infusion was found to be decreased. From these data, it is concluded that the decrease in glucose tolerance in patients with Graves' disease can be explained by 1) the impairment of early insulin release response to rapid intestinal glucose absorption, 2) increased insulin metabolic clearance and 3) hyperglucagonemia.

Abstract
The difference in the acute metabolic change in ketone bodies between patients with insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) was investigated in this study. The subjects employed were 7 patients with IDDM losing residual insulin secretion and 7 patients with NIDDM matched to the former patients for age, body mass index, duration of diabetes, daily insulin dosage, fasting plasma glucose and HbA1c. Blood samples were drawn at 3A.M. and 7A.M. on the same day, and plasma glucose, acetoacetic acid (AcAc), 3-beta-hydroxybutylic acid (3-OHBA), free fatty acid (FFA), glycerol, cortisol and growth hormone (GH) concentrations were determined. Plasma total ketone bodies (AcAc and 3-OHBA), 3-OHBA and FFA concentrations at 7A.M. were significantly higher in the patients with IDDM than in those with NIDDM (p < 0.05), while there were no significant differences in any other parameters at 3A.M. between the patients with IDDM and those with NIDDM. The ratios of 7A.M. value/3A.M. value of total ketone bodies, AcAc and 3-OHBA concentrations were also more significantly elevated in the patients with IDDM than in those with NIDDM. It was observed that the ratio of 3-OHBA was more than 2.0 in all of the patients with IDDM and less than 2.0 in all of the patients with NIDDM, the difference being significant with p < 0.001.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Clinical studies were undertaken of three pairs of monozygotic twin sisters affected by Graves' disease. The evidence that the twins were monozygotic was established by similarity in physical appearance, identical blood-group antigens and identical HLA types. All pairs were female, and the evidence of Graves' disease in both members of the pair was observed in 2 out of 3 pairs. In the remaining pair the disease started in the elder sister, but the younger sister still remained in euthyroidism in spite of the presence of diffuse goiter. The disease occurred in the second decade in all the patients, and the interval between the occurrence of the disease in twin sisters was 1 to 4 years. No common specific type of HLA was found among all three pairs, but DR4 was common in two pairs of twin sisters showing positive MCHA test. Serum TRAb was positive in 2 pairs of twin sisters but negative in the remaining one. However, it became positive in the elder sister of the latter pair during the antithyroid treatment. The effect of antithyroid drug treatment was found to be similar in each of the twin sisters, and the serum TRAb moved almost in parallel with serum FT4 level. These results indicate that a genetic factor may be of great importance in the aetiology of Graves' disease, and there was a strong preponderance for it to occur in women and the second decade was the peak age for its occurrence. The common specific type of HLA for all Graves' patients was not found in this study. A strong relationship was observed between Grave's disease and TRAb.
