Abstract
To reconstruct a composite mandibular defect, we have simultaneously transferred a vascularized bone graft or osteocutaneous flap together with a forearm flap. The radial forearm flap, being thin, pliable, and having a long vascular stalk, served as mucosal lining and/or an interpositional flap acting as a vascular bridge. Between 1982 and 1989, we used this procedure in 17 patients with a mandibular defect or deformity which developed following treatment of oral cancer. Our clinical experience has demonstrated that this dual free tissue transfer has many advantages. It is useful for obtaining a good alveolar ridge in patients with a composite mandibular defect. It is applicable in cases where only a single pair of recipient vessels are present and may be useful when the recipient vessels are positioned some distance from the defect.

Abstract
This article represents the first evidence that the renal secretion of the commonly used drug, digoxin, is mediated by P-glycoprotein. In this study, it was demonstrated that digoxin is a substrate of P-glycoprotein, and the mechanism of a clinically important drug interaction, such as digoxin-quinidine, was elucidated. Human P-glycoprotein was expressed on the apical membrane of the porcine kidney epithelial cell line, LLC-PK1 by transfecting with human MDR1 cDNA. The expression and function of P-glycoprotein were confirmed by Southern and Western blotting, RNase protection assay, immunostaining and transporting activity for vinblastine. The transepithelial transport of [3H]digoxin was measured across the cell monolayers grown on microporous polycarbonate membrane filters. The transfectant cells exhibited markedly greater basal-to-apical transport and less apical-to-basal transport than the host cells, and the former was 8-fold greater than the latter. The augmented transepithelial transport resulted from the increased efflux from cells to apical side. This oriented transport was inhibited by the presence of 20 microM vinblastine, quinidine or verapamil. The rate of efflux to the apical side was 2-fold greater than that to the basal side. Quinidine inhibited the efflux to the apical side but did not affect transport into the basal side. These findings demonstrate that digoxin is transported by human P-glycoprotein, which is a previously undiscovered drug transport system in the kidney other than organic cation and anion transport systems, and suggest a molecular mechanism for the renal tubular secretion of digoxin as well as clinically important digoxin-quinidine interaction via P-glycoprotein.

Abstract
We analyzed the medical records of nine patients with severe rapid cycling affective disorders (RCAD), and determined the cycle of mania occurrences by calculating the period between two successive onsets of mania for each patient. Using the cycle as the index we devised a cycle-oriented diagram by dividing the observation period by the index cycle, and visually studied the mode of episode occurrences. In seven patients, the onset of mania generally followed the index cycle, but sometimes shifted from the day estimated by the index cycle. The shift seemed to be caused by a cycle other than the index cycle, which appeared temporarily in the course. The period between two successive onsets of mania was often several times longer than the index cycle length. In patients with RCAD, some sort of periodic rhythms may possibly control the course of episode occurrences on a continuing basis.

Abstract
The E4 open reading frame (ORF) of human papillomaviruses (HPVs) is transcribed in abundant mRNAs encoding an E1/E4 fusion gene during the productive infection, and the HPV 16 E7 ORF encodes an oncoprotein detectable in the cell lines derived from cervical carcinoma. We examined 421 human sera, which included 108 samples from the patients with cervical carcinoma, for the presence of IgG antibodies against the HPV 16 E4 and E7 proteins by enzyme-linked immunosorbent assay. Bacterially expressed fusion protein lac-E1/E4 and nonfusion protein E7 were purified and used as antigens. All of the 22 serum samples positive for anti-E7 antibody and the 11 out of 15 samples positive for anti-E1/E4 antibody were from the patients with cervical carcinoma, but only one sample was found to contain both anti-E1/E4 and anti-E7 antibodies. These findings show specific and independent association of these antibodies with cervical carcinoma.

Abstract
In the human brain, alternative splicing of amyloid precursor protein (APP) gene transcript generates at least three types of mRNA coding for APP770, APP751 and APP695. The former two types harbor, but the latter one lacks a domain of Kunitz-type serine protease inhibitor (KPI). We studied, by using the RNase protection technique, the expression of APP mRNAs in brains of Alzheimer's disease (AD) and other neurological disorders with special reference to aging. We found that the ratio of (APP770 mRNA+APP751 mRNA)/APP695 mRNA in the frontal cortex increased approximately 1.5-fold in AD compared with other neurodegenerative or cerebrovascular disorders. The ratio in other neurological disorders did not change significantly from control even in their affected brain regions. On the other hand, we found a positive correlation between the ratio and age; the ratio (y) increased gradually with the advance of age (x) as expressed by y = 0.005x + 0.014 (r = 0.372) for the AD group, and y = 0.004x -0.037 (r = 0.486) for the non-AD group. These correlations indicate that the AD brain reached the same ratio of KPI-harboring to lacking APP mRNAs a few decades earlier than the non-AD brain in senescence. This finding of AD-specific and age-related change led us to the idea that a relative increase in KPI-harboring APPs over a KPI-lacking APP may perturb normal degradation of APPs, thereby leading to deposition of beta A4 protein as amyloid.

Abstract
To investigate the frequency of exposure to hepatitis C virus (HCV) in chronic liver disease, sera from Japanese patients were tested with the original anti-HCV assay (Ortho) and an anti-HCV assay based on synthetic peptides corresponding to a variety of regions in the HCV genome. Thirty-one (67%) of 46 patients with chronic non-A,non-B hepatitis were anti-HCV-positive by the Ortho ELISA, 20 of whom were also positive by ELISA based on synthetic HCV peptides. Eight (53%) of the 15 patients negative by the Ortho ELISA tested positive for anti-HCV by ELISA based on HCV peptides. Serum HCV RNA was detected in all cases positive for antibody to the HCV peptide and in 14 (78%) of 18 cases without antibody. Thirty-seven hepatitis B virus carriers were without anti-HCV by the Ortho ELISA and were negative for serum HCV RNA, six (16%) of whom were positive by ELISA based on HCV peptides. Antibody responses were directed against each synthetic HCV peptide used, with a considerable difference in incidence, indicating possible expression of the corresponding region in the course of HCV propagation. These findings indicate that exposure to HCV may be more common than expected based on the results of the Ortho ELISA.

Abstract
In order to obtain specific antisera for use in the enzyme immunoassay of 25-hydroxyvitamin D3, three hapten-carrier conjugates having different lengths of bridges at the C-3 position were prepared from 25-hydroxyvitamin D3 by coupling with bovine serum albumin using the active ester method. The specificity of anti-25-hydroxyvitamin D3 antisera elicited in rabbits was tested by a cross-reaction study with closely related secosterols and by measuring the plasma levels of 25-hydroxyvitamin D3 by means of radioimmunoassay using tritium-labeled antigen. The results indicated that the specificity of the antisera obtained is higher than that of vitamin D-binding protein, and that some of these antisera are suitable for enzyme immunoassay.

Abstract
An intrasplenic pseudocyst associated with the acute relapsing phase of chronic pancreatitis in a 51-year-old woman is reported, with a review of the Japanese literature. The patient was admitted with a complaint of left lateral and back pain. Abdominal US and CT revealed communicating cysts at the pancreatic tail and the subcapsule of the spleen. A repeat US and CT 1 month after admission demonstrated enlargement of the cyst at the pancreatic tail. ERCP revealed a dilated main pancreatic duct without any definite evidence of stenosis, and direct communication with the cyst at the pancreatic tail. Percutaneous cystography revealed that the subcapsular cyst of the spleen, the cyst of the pancreatic tail, and the main pancreatic duct communicated with each other. The cyst contained serous fluid with an amylase content of 57,500 IU/I. Distal pancreatectomy and splenectomy was performed. Histologically, there was a nonepithelial lining on the inner surface of the cysts at the pancreatic tail and the subcapsule of the spleen. Severe chronic inflammatory changes were present in the resected tail of the pancreas. Timely surgical treatment is advocated to reduce the mortality and morbidity associated with complications of intrasplenic pseudocysts.

Abstract
A rapid and efficient capillary gas chromatography was utilized to measure urinary galactitol in 133 non-galactosemic children on a free diet. The children aged from 12 days to 14 years were divided by age into six groups. The urinary galactitol concentration was found to be the highest (64.04 mmol/mol creatinine) in the neonatal group and the lowest (7.12 mmol/mol creatinine) in the group over 2 years old. It is concluded that the urinary concentration of galactitol is strongly age-dependent.

Abstract
Human T-cell leukemia virus type 1 (HTLV-1) induces adult T-cell leukemia and also a neurological disease, tropical spastic paraparesis. Tax protein (p40tax) of HTLV-1 activates in trans its own transcriptional enhancer in the long terminal repeat and also those in some cellular genes such as interleukin 2 receptor alpha, granulocyte-macrophage colony-stimulating factor, Fos, Jun and MHC class I. Thus, Tax has been proposed to play a critical role in the pathogenesis induced by HTLV-1 infection. Here, we report formation of a complex of Tax protein with the precursor protein p105 of the NF-kappa B p50 subunit. p105 was co-immunoprecipitated with Tax protein from cells infected with HTLV-1 from cells transfected with the Tax expression plasmid, but not from cells transfected with inactive mutants of Tax. Furthermore, a GST-p105 fusion protein produced in Escherichia coli bound to Tax protein. These results strongly suggest that the trans-activator Tax protein forms a complex with precursor NF-kappa B p105 and plays a role in trans-activation of transcriptional initiation.

Abstract
The human hepatoblastoma-derived cell line HB611 secretes hepatitis-B surface antigen (HBsAg) and hepatitis-B e antigen (HBeAg) into the medium. Hepatitis-B-virus (HBV) DNA integrated into the cellular genome was found to be hypermethylated. When the cells were treated with 5-azacytidine for 3 days, the level of HBsAg in the medium increased, while the level of HBeAg remained constant. The level of alpha-fetoprotein (AFP) decreased with the 5-azacytidine treatment. Southern blot analysis of DNA digested with HpaII or MspI showed that 5-azacytidine treatment resulted in hypomethylation of the integrated HBV DNA, suggesting that 5-azacytidine increased HBsAg production in the cells through hypomethylation of the HBV genomic DNA.

Abstract
We previously reported evidence for a statistical association between the serologically determined HLA-Bw54, DR4 and DRw53 alleles and the non-immune responsiveness to hepatitis B virus surface antigen (HBsAg) in the Japanese population. To identify the locus and allele within the HLA region associated with the nonresponsiveness to HBsAg, serological HLA typing, DNA typing of HLA-DQ and DP alleles using amplified HLA genes and sequence-specific oligonucleotide probes, and restriction fragment length polymorphism (RFLP) analysis of the fourth component of complement (C4) genes were performed in healthy unrelated Japanese vaccinees who were immunized subcutaneously three times with plasma-derived HBsAg vaccine. In nonresponders to HBsAg, the frequencies of HLA-Bw54 cross-reactive epitope group (CREG); (Bw54, Bw55, Bw56 and other Bw22), C4 RFLP (6.5 kb + 12.0 kb), DR4, DRw53 and DQw4 (DQA1*0301-DQB1*0401) were increased and the frequencies of HLA-DR1, DRw6 and DQw1 were decreased as compared with those in healthy unrelated controls. Further analysis revealed that the coexistence of HLA-Bw54CREG and DR4-DRw53-DQw4 (DQA1*0301-DQB1*0401) was associated with the nonresponder group, whereas, donors positive for exclusively either Bw54 CREG or DR4-DRw53-DQw4 (DQA1*0301-DQB1*0401) were not associated with the nonresponder group. Because there is a strong linkage disequilibrium between HLA-Bw54CREG, C4 RFLP (6.5 kb + 12.0 kb) and HLA-DR4-DRw53-DQw4 (DQA1*0301-DQB1*0401) in the Japanese population, the extended HLA-Bw54CREG-C4 RFLP (6.5 kb + 12.0 kb)-DR4-DR-w53-DQw4 (DQA1*0301-DQB1*0401) haplotype may well control nonimmune responsiveness to HBsAg. This extended HLA haplotype controls nonresponsiveness as a dominant genetic trait because all ten heterozygotes and two of three probable homozygotes of this extended HLA haplotype were nonresponders.

Abstract
We studied the growth of 89 patients who were long-term survivors of childhood leukemia and lymphoma. Eight patients with CNS relapse had a greater decrease in height standard deviation score (SDS) after the relapse than 81 patients without CNS relapse (p less than 0.0001). Two patients who received cranial irradiation when they were younger than 2 years of age demonstrated a marked decrease in height SDS more than 3.0 SD. Five patients appeared to have a decline in height SDS before their CNS relapse. There were no apparent changes in the weight of patients with or without CNS relapse. In endocrine studies, all eight patients with CNS relapse failed to show the normal growth hormone (GH) response to arginine, GH-releasing factor, and glucagon-propranolol tests, while spontaneous GH secretion during sleep was normal. Magnetic resonance imaging (MRI) revealed small pituitary glands in seven patients with CNS relapse. These findings suggest that in leukemia and lymphoma patients with CNS relapse, GH secretion is impaired at the hypothalamic level, resulting in a secondary atrophy of the pituitary gland. The MRI together with selected endocrinologic tests may help to clarify the mechanism of growth impairment in such patients. A decline in height SDS in each patient may be a useful marker for predicting a CNS relapse in a child with leukemia or lymphoma.

Abstract
To ascertain anorexigenic effect of toxohormone-L, a polypeptide extracted and purified from ascites of patients with hepatoma were infused into the rat third cerebroventricle. Food intake decreased on the first day after infusion of an optimum dose of 10.0 micrograms (p less than 0.05). The suppressive effect on feeding was linearly dose dependent (p less than 0.05). Meal size and latency to the first meal decreased in the 12-h dark period, and the first and the second 4-h cumulative blocks after infusion of a 10.0 micrograms dose (p less than 0.01 for each). The suppressive effects on total food intake and meal size were completely recovered within 24 h after infusion. Neither postprandial intermeal interval nor eating speed was affected. Periprandial drinking, a ratio of water intake to food intake, was not affected after infusion of 5.0 and 10.0 micrograms toxohormone-L. Infusion of a 10.0 micrograms dose showed no effect on ambulation. These findings suggest that anorexia and cachexia produced in cancer patients may essentially be due to the suppressive effect of toxohormone-L on food intake.

She developed hyponatremia and beriberi heart disease, which resulted in metabolic acidosis and cardiogenic shock (shoshin beriberi). Mechanical ventilation was applied for pulmonary edema. Right heart failure was improved after administering vitamin B1. However, 5 days after the shock, hypoxemia and diffuse radiographic infiltrates progressed, and a diagnosis of adult respiratory distress syndrome (ARDS) was made. After the occurrence of an air leak, the patient died of respiratory failure. The cardiogenic shock and pulmonary edema due to cardiac beriberi may have triggered the ARDS.

Abstract
A murine monoclonal antibody (MDR3M) (isotype: IgM) reactive with mdr3 gene product was generated by immunizing mice with mdr3-specific peptide (H2N-12WRPTSAEGDFELGISSKQKRKKTKTVKMI41G-COOH) and hybridizing the primed mouse splenic B cells with X63-Ag8,6.5.3 mouse plasmacytoma cells. MDR3M did not cross-react with mdr1 gene product. This monoclonal antibody may be useful for analyzing the role of mdr3 gene product in cells and tissues.
