Abstract
A 21-year-old man was referred to our hospital because of a liver mass lesion detected by abdominal ultrasonography. He had received no hormonal treatment. Physical examinations revealed no abnormalities, and laboratory data, including hepatic function test results, were within normal ranges, with the exception of elevated levels of serum protein induced by vitamin K absence or antagonist (PIVKA)-II (2.2 AU/ml). Abdominal ultrasonography revealed a hyperechoic mass lesion measuring 10 x 10 cm, with hypoechoic areas located in the right posterior segment of the liver. A low-density area and a hypervascular area were detected in the right posterior segment of the liver by computed tomography and celiac angiography, respectively. As hepatocellular carcinoma could not be completely excluded, the tumor was resected. The tissue consisted of sheets of tumor cells with eosinophilic cytoplasm and round nuclei showing a thin trabecular pattern, and these histological findings indicated liver cell adenoma. After resection of the tumor, serum PIVKA-II returned to the normal level.

Abstract
We measured serum concentrations of nitrite/nitrate (NOX), type II phospholipase A2 (PLA2), leukotriene B4 (LTB4), and platelet-activating factor (PAF) in patients with sepsis. These findings were compared between patients with and without septic shock. Serum concentrations of NOX, type II PLA2, LTB4, and PAF acetylhydrolase (PAF-AH) were significantly higher in the group with septic shock (P < 0.0001; P = 0.0060; P = 0.0052; P = 0.0052), indicating the severity of the disease. There were significant correlations between the serum NOX level and serum levels of type II PLA2, LTB4, and PAF-AH (r = 0.6890, P < 0.0001; r = 0.3755, P = 0.0409; r = 0.5095, P = 0.0040, respectively). It is speculated that LTB4 and PAF, both produced with type II PLA2, interact with each other and are involved in the deterioration of pathologic features associated with sepsis. Furthermore, nitric oxide (NO) and eicosanoids interact to play an important role in vascular dilatation during septic shock.

Abstract
A 61-year-old woman was admitted to the hospital because of general fatigue. Laboratory examinations showed hyponatremia, plasma hypo-osmolarity, and inappropriate increased concentration of the plasma antidiuretic hormone (ADH) in the presence of concentrated urine. Magnetic resonance imaging revealed a mass lesion in the anterior mediastinum. An extended thymectomy was performed under the diagnosis of thymoma with the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Histologically the tumor was located in the thymic tissue and was diagnosed as ganglioneuroblastoma. Immunohistochemical studies showed the existence of ADH in the tumor cells. To the knowledge of the authors, this is the first case of ganglioneuroblastoma of the thymus with SIADH.

Abstract
We assessed the plasma levels of nitrite/nitrate (NOx) and soluble Fas antigen (sFas) in patients with multiple organ failure (MOF). The NOx levels showed high levels in MOF patients with sepsis and without infection. A significant difference was not seen between the MOF patients complicated by sepsis and uncomplicated by infection, although the NOx levels in the former group tended to be higher. There was a significant correlation between NOx levels and sFas levels in MOF patients. Both sFas and NOx levels were high during MOF, and rapidly decreased when MOF was relieved. These findings suggest that sFas and NOx contribute to the development of MOF.

Abstract
We studied the genetic basis of familial neurohypophyseal diabetes insipidus in a Japanese family. The members had polyuria and a deficiency of plasma vasopressin (AVP). Polymerase chain reaction (PCR) amplified exons of the AVP-neurophysin-II gene were subcloned and sequenced. Exons 1 and 3 were normal, but nucleotide 1884 Guanine (G) in exon 2 was substituted with Thymine (T), which induced a substitution of glycine (Gly) for valine (Val). To examine the presence of this mutation in the affected subjects, we designed two mutated primers. One of them induced a new endonuclease restriction site in the PCR fragments from normal, and the other induced a new endonuclease restriction site from patients with the mutation. DNA fragments from two affected members of this family were amplified with this primer, and the PCR products were digested by endonuclease and resolved by electrophoresis. The results indicated that these subjects had both normal and mutant alleles, indicating that the mutation was heterozygous. We concluded that this mutation caused neurohypophyseal diabetes insipidus in this family.

Abstract
Based upon DNA sequence data and positive immunochemical reactivity of expressed protein, novel homologues of the FNR family were identified in four representative oral facultative anaerobes: Capnocytophaga ochracea, Capnocytophaga sputigena, Haemophilus aphrophilus, and Actinobacillus actinomycetemcomitans. The similarity to E. coli FNR and to HlyX (itself 71% similar to E. coli FNR, while regulating expression of hemolysin operon in Actinobacillus pleuropneumoniae) was estimated from the deduced partial amino acid sequence to be, in the above order of tested species, 98, 98, 86, and 85%, and 75, 75, 88, and 88%, respectively. The phylogenetic relatedness indicates a rather closer link of HlyX to the FNR homologues from both pathogens, H. aphrophilus and A. actinomycetemcomitans. The possibility that the A. actinomycetemcomitans FNR homologue functions as a redox-sensing transcriptional factor to regulate, in addition to anaerobic respiration, microaerobic expression of the leukotoxin operon (ltx gene) is suggested.

Abstract
The effects of extracellular ATP on cytosolic Ca2+ concentrations ([Ca2+]i) and cell membrane potentials (Vb) of rabbit renal proximal tubules were investigated using fura 2 and microelectrodes. ATP transiently increased [Ca2+]i without an apparent sustained phase, and the maximum effect was obtained at 10 microM. ADP, adenosine 5'-O-(3-thiotriphosphate), and 2-methylthioadenosine 5'-triphosphate were equally effective as ATP, whereas UTP, adenosine, and alpha beta-methyleneadenosine 5'-triphosphate were far less effective. The [Ca2+]i responses to ATP were strongly inhibited by reactive blue 2, a P2-purinergic receptor antagonist. The removal of extracellular Ca2+ as well as the addition of thapsigargin also markedly attenuated the responses to ATP. In addition, ATP had virtually no effect on Vb, except for the occasional small depolarization by 300 microM ATP. These results indicate that extracellular ATP increases [Ca2+]i through a P2-purinergic receptor and that this effect of ATP is dependent on both extracellular and intracellular Ca2+.

Abstract
Tumor necrosis factor-alpha (TNF-alpha) has been demonstrated to selectively decrease the production of type I and type III collagens in human dermal fibroblasts. The effects of the commonly used food antioxidants, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), alpha-tocopherol, propyl gallate, superoxide dismutase (SOD), and catalase on TNF-alpha-induced growth enhancement and collagen metabolism were evaluated in the present study. BHA at concentrations of both 5 x 10(-5) and 10(-4) M inhibited cell proliferation and DNA synthesis induced by 10 ng/ml TNF-alpha in human dermal fibroblasts, while other antioxidants had minimal effects. Further, BHA (5 x 10(-5) M and 10(-4) M) significantly blocked TNF-alpha-induced decreases in collagen synthesis. These results suggest that antioxidants such as BHA may be involved in the modulation of collagen synthesis by TNF-alpha in human dermal fibroblasts.

Abstract
We present a novel scheme of visible gray-image morphology with the visual-area-coding technique (VACT). The VACT is a technique of digitized analog-optical computing in which data are converted into visible coded patterns and processed with the visible form. Because the achievable operations in the VACT are identical to those of mathematical morphology, mathematical morphology is adapted to gray-image morphology with the VACT. Computer simulation and optical experiments of the several operations in mathematical morphology verify the correctness of the proposed technique. The processing capacity of the proposed method is estimated in terms of the space-bandwidth product.

Abstract
To investigate the involvement of nitrite/nitrate oxide (NOx) in septic shock, and to evaluate the relationships between NOx and cytokines in patients with this disorder, we evaluated 11 patients with septic shock and 12 patients with sepsis unassociated with shock. NOx were measured with an automated system based on the Griess reaction. The plasma concentrations of various cytokines were determined by enzyme-linked immunosorbent assay. Endotoxin was determined by a specific assay after the plasma samples were processed by a perchloric acid method. The mean plasma levels of NOx in the group with shock significantly exceeded those in the group without shock. Significant correlations were observed between the plasma levels of NOx and those of endotoxin, tumor necrosis factor-alpha, and interleukin 8 in both groups. NOx appeared to be involved in the development of septic shock in humans. Endotoxin and cytokines appeared to be involved in the production of NOx.

Abstract
We assessed the blood interleukin 11 (IL-11) levels in patients with disseminated intravascular coagulation (DIC). The IL-11 level exceeded the detection limit, i.e., IL-11 was positive, in 14 of the 21 patients in the group with DIC complicated by sepsis, with a mean value of 20.4 pg/ml. In the group with DIC uncomplicated by infection, IL-11 levels were above the detection limit in 8 of the 17 patients, and the average level was 10.6 pg/ml. The difference between the IL-11-positive rate in the two groups was not significant. Although IL-11 levels tended to be higher in the group with sepsis as a complication, the difference was not significant. The elevated IL-11 levels observed in patients with DIC, with or without complication by infection, seem quite appropriate as a biological response to increased platelets.

Abstract
A decreased concentration of dehydroepiandrosterone sulfate (DHEA-S) in patients with Alzheimer's disease (AD) has been reported but is still controversial. In the present study, serum concentrations of DHEA and DHEA-S were determined in 19 patients with AD, 21 patients with cerebrovascular dementia (CVD) and 45 age- and gender matched elderly control individuals from the Japanese community at large. Serum concentration of DHEA among controls, patients with AD and patients with CVD did not significantly differ from one another. However, patients with AD and patients with CVD were found to have lower concentration of serum DHEA-S and a lower DHEA-S/DHEA ration compared to normal control individuals. No significant difference was observed in the concentration of serum DHEA-S or the DHEA-S/DHEA ratio between patients with AD and those with CVD. These results suggest that reduced concentrations of serum DHEA-S may not be unique to AD, but instead reflect a common phenomenon in dementing diseases. However, since serum concentration of DHEA in these patients remained unchanged, the significance of DHEA in dementia remains unclear.

Abstract
Intercellular adhesion molecule-1 (ICAM-1, CD54), an adhesion molecule of the immunoglobulin superfamily, is an endothelial cell surface ligand for such leukocyte integrins as lymphocyte-function-associated molecule 1 (LFA-1, CD11a/CD18), Mac-1 (CD11b/CD18) and CD43. These molecules mediate adhesive interactions between leukocytes and endothelial cells and are critically involved in infiltration of leukocytes into inflammatory lesions. We examined the expression of ICAM-1 in renal tissues of Masugi nephritis rats and directly examined the role of ICAM-1 by administration of neutralizing monoclonal antibodies (MAbs) to rat ICAM-1, LFA-1 alpha-subunit (LFA-1 alpha), beta-subunit (LFA-1 beta) and Mac-1 alpha-subunit (Mac-1 alpha). Within 3 h after injection of nephrotoxic serum, increased expression of ICAM-1 was detected in the glomeruli by in situ hybridization and an immunofluorescence study. Proteinuria was significantly suppressed by the MAbs against ICAM-1, Mac-1 alpha and LFA-1 beta. Neutrophil infiltration into the glomeruli was significantly prevented by injection of the MAbs against ICAM-1, LFA-1 alpha and LFA-1 beta. These results indicate that both ICAM-1/LFA-1 and ICAM-1/Mac-1 pathways are involved in neutrophil infiltration into the glomeruli. On the other hand, monocytic infiltration was prevented by the MAbs against ICAM-1, LFA-1 alpha and LFA-1 beta but not by anti-Mac-1 alpha MAb. Due to these results, ICAM-1 is considered to be a critical molecule involved in the pathogenesis of the leukocyte infiltration into the glomeruli in the heterologous phase of Masugi nephritis. Anti-ICAM-1 antibody may be beneficial in the treatment of leukocyte-mediated glomerular diseases.

Abstract
The present study was conducted to determine whether a plasma interleukin-1 receptor antagonist (IL-1ra) would reflect the severity of burn injury and to examine the relation between IL-1ra and the cytokines. We studied 24 burn patients in whom the total burn surface area (TBSA) accounted for at least 20% of the body surface, and in whom serial blood samples could be obtained beginning immediately after the burn injury. Plasma levels of IL-1ra were determined by enzyme-linked immunosorbent assay (ELISA). Plasma levels of tumor necrosis factor-alpha (TNF-alpha), IL-6, and IL-8 were also determined by ELISA. Endotoxin was measured by an endotoxin-specific synthetic substrate method. There was a significant correlation between the plasma levels of IL-1ra and TBSA during the first week following burn injury. The IL-1ra level was the highest immediately after the burn injury. The level decreased markedly thereafter, and again rose when infection occurred. The IL-1ra level was extraordinarily elevated in patients who developed concomitant sepsis, septic shock or the septic multiple organ dysfunction syndrome. The IL-1ra level on admission and the maximum IL-1ra level during the observation period were significantly higher in the patients who eventually died than in the survivors. There was a significant correlation between the level of IL-1ra and that of TNF-alpha, IL-6 or IL-8 during the observation period. No correlation was found between IL-1ra and endotoxin. The plasma IL-1ra level was closely correlated with the severity of inflammation and the clinical status of the burn patients, regardless of the infection. Results suggest that IL-1ra can serve as an index of the systemic inflammatory response syndrome (SIRS).
