    Notes: Background  Neuropsin (KLK8), a serine protease of the kallikrein family, is thought to be involved in the function of keratinocytes, i.e. migration, differentiation and desquamation. However, how neuropsin participates is still unknown.Objective  To observe the epidermal function of serine protease in neuropsin-deficient mice.Methods  We irradiated the skin of neuropsin-deficient mice with ultraviolet light to induce acute inflammation and compared the morphology with that of wild-type mice.Results  We observed a phenotypic change in the epidermis. An acute inflammatory dose of ultraviolet light induced a marked increase in neuropsin mRNA expression in the skin. The signal intensity of the mRNA expression was highest on day 2–3 after irradiation, when keratinocytes were aligned irregularly in the recovery period. Morphological comparison between neuropsin –/– and +/+ mice revealed that an irregular alignment of cells in the thickened epidermis was obvious on day 2 after irradiation in the wild-type mice, whereas it was prolonged for at least 2 days in the neuropsin-deficient mice. The stratum corneum of neuropsin-deficient mice was remarkably thicker than that of the wild-type mice at 5, 14 and 21 days after irradiation. The increase, as a response to this stimulus, in involucrin immunoreactivity, a marker for cell envelope assembly, was delayed in the mutant mice.Conclusions  Thus, neuropsin might be involved early in the process of differentiation, such as in the assembly of the cell envelope, but not in migration and desquamation.

    Notes: Abstract The objective of this study was to determine the role of serum KL-6 levels as a marker for the activity of interstitial pneumonia in patients with connective tissue diseases. The serum concentrations of KL-6, a glycoprotein produced mainly by pulmonary type II epithelial cells, were measured in 21 patients with connective tissue disease. The activity of interstitial pneumonia was compared with the associated serum KL-6 concentrations. Serum KL-6 concentrations in patients with interstitial pneumonia were significantly higher than those in the controls. Among patients with active interstitial pneumonia, serum KL-6 concentrations following the treatment (after improvement) were significantly lower than the pretreatment values. The extent of the pulmonary fibrosis correlated positively with the serum KL-6 concentrations during the inactive phase of the interstitial pneumonia. These results suggest that sequential measurement of serum KL-6 levels is a new and useful means for the evaluation of interstitial pneumonia in patients with connective tissue diseases.

    Notes: Abstract  We report the case of a 43-year-old man who presented with an osteolytic and expansive lesion in the left distal femur mimicking a giant cell tumor. Magnetic resonance imaging (MRI) showed that most of the lesion was cystic, and histological examination revealed fibrous dysplasia with marked cystic degeneration. Radiographic findings of cystic fibrous dysplasia in the end of a long bone may be similar to those of a giant cell tumor, and a biopsy is essential for the final diagnosis.

    Notes: Abstract Background: To determine whether a difference exists in the relative ability of power Doppler sonography and conventional color Doppler sonography to detect the intratumoral vasculature of hepatocellular carcinoma based on lesion size and location. Methods: Sixty patients with 88 hepatocellular carcinoma lesions that showed tumor staining on angiography and were enhanced on dynamic computed tomography were evaluated. Power Doppler sonography and color Doppler sonography were used to detect the intratumoral vasculature, and their sensitivity to blood flow was evaluated. Results: Power Doppler sonography showed a superior detection rate for lesions smaller than 2 cm and located 4–8 cm from the abdominal surface in the right hepatic lobe as compared with color Doppler sonography (p 〈 0.01). Neither power Doppler sonography nor color Doppler sonography depicted the intratumoral vasculature of lesions located more than 8 cm from the abdominal surface (n = 14). Both color Doppler imagings exhibited a low detection rate for lesions in the left hepatic lobe (n = 31, p 〈 0.01). Conclusions: Power Doppler sonography should be applied in the evaluation of small or intermediate depth lesions because it is more sensitive to these lesions than color Doppler sonography, but it is not useful for left lobe and deep lesions.

    Treatment of dark-grown Arabidopsis thaliana with a brassinosteroid-biosynthesis inhibitor, brassinazole, induces some characteristics of light-grown plants (2000)

    Notes: Abstract. When a brassinosteroid biosynthesis inhibitor, brassinazole (Brz), was applied at concentrations ranging from 0.1 to 2 μM, Arabidopsis thaliana (L.) Heynh seedlings grown in the dark exhibited morphological features of light-grown plants, i.e. short hypocotyls, expanded cotyledons, and true leaves, in a dose-dependent manner. Control (non Brz-treated) seedlings grown in the dark for 40 d did not develop leaf primordia. However, treatment with the lowest concentration of Brz induced the development of leaf buds, although it hardly induced any short hypocotyls, and treatment with the highest concentration of Brz induced both short hypocotyls and leaves. Labeling experiments with the thymidine analogue 5-bromo-2′-deoxyuridine revealed that amplification of cell nuclei and organellar nucleoids is activated in the shoot apical meristems of dark-grown Brz-treated seedlings. These results suggest that Brz-treatment induces development of true leaves. Furthermore, condensation and scattering of plastid nucleoids, which is known to occur during the differentiation of etioplasts into chloroplasts, was observed in the plastids of dark-grown Brz-treated cotyledons. In addition, high levels of ribulose-1,5-bisphosphate carboxylase-oxygenase proteins accumulated in the plastids of the cotyledons. Electron microscopy showed that the plastids were etioplasts with a prolamellar body and few thylakoid membranes. These results suggest that Brz treatment in the dark induces the initial steps of plastid differentiation, which occur prior to the development of thylakoid membranes. This is a novel presumed function of brassinosteroids. These cytological changes seen in Brz-treated Arabidopsis were exactly the same as those seen in a brassinosteroid-biosynthesis-deficient mutant, det2, supporting the hypothesis that Brz has no side-effects except inhibiting brassinosteroid biosynthesis, and should prove a useful tool in clarifying the role of brassinosteroids.

    Notes: Abstract Background: Endogenous morphine in the brain leads to various biological responses after surgery. The aim of this study was to determine whether morphine levels in the plasma would be enhanced by open laparotomy rather than by laparoscopic procedures. Methods: We compared 19 patients who underwent laparoscopic cholecystectomy with five patients who underwent resection of the gallbladder by open laparotomy. Morphine levels in the plasma were measured by an electrochemical detection system. Results: Postoperative endogenous morphine levels were higher with open laparotomy than with the laparoscopic technique (three h after surgery: open, 200 ± 52.6 fmol/ml vs laparoscopy, 17.6 ± 3.7, p 〈 0.01). This morphine elevation accounted for higher levels of cytokine, greater pain scores, and longer duration of fasting in open laparotomized patients than in laparoscopic cholecystectomy patients. Stress hormone levels in the plasma were also higher with open laparotomy than with laparoscopy. Conclusion: Morphine synthesis was enhanced by open laparotomy, resulting in greater biological response postoperatively than that seen with laparoscopic cholecystectomy.

    Notes: Abstract This study aims to evaluate the validity and reliability of a Japanese version of the Arthritis Impact Measurement Scales, version 2 (AIMS2) for patients with rheumatoid arthritis (RA). The Japanese version of the AIMS2 questionnaire was administered to 1643 patients with classical or definite RA at 11 hospitals nationwide in Japan. Reliability was assessed by a test–retest procedure, 4 weeks apart, using 75 randomly selected patients. Internal consistency was measured by Cronbach's α, and factor analysis was used to obtain the proportion of variance explained by the first factor in principal component analysis. The validity of the AIMS2 scales was assessed by internal standards. Internal consistency (α coefficients, 0.84–0.94), test–retest reliability (intraclass correlation coefficients, 0.75–0.93), and factor analysis (0.62–0.85) of the AIMS2 health status scales proved that they are highly reliable in the Japanese version. Validity, as measured by the relationships among the scores on the questionnaire items, was also sufficiently secured. The validity and reliability of the Japanese version of the AIMS2 are sufficient for all practical purposes when compared with the original and with other translated versions of the questionnaire.

    Characterization of staurosporine-sensitive mutants of Saccharomyces cerevisiae: vacuolar functions affect staurosporine sensitivity (2000)

    Notes: Abstract Mutations at several loci affect the sensitivity of the yeast Saccharomyces cerevisiae to staurosporine. We report here the characterization of novel staurosporine- and temperature-sensitive mutants (stt). Cloning and integration mapping showed that the genes STT2/STT6, STT5, STT7, STT8 and STT9 are allelic to VPS18, ERG10, GPI1, VPS34 and VPS11, respectively. The products of ERG10 and GPI1, respectively, catalyze mevalonate and glycosyl phosphatidylinositol anchor synthesis, while VPS18 and VPS11 genes belong to the class C VPS (Vacuolar Protein Sorting) genes, and the VPS34 gene is classified as a class D VPS. Therefore, staurosporine sensitivity is affected by ergosterol and glycolipid biosynthesis and by vacuolar functions. We found that other vps mutants belonging to classes C and D exhibit staurosporine sensitivity, and that they show calcium sensitivity and fail to grow on glycerol as the sole carbon source; both of the last two characteristics are shared by vacuolar H+-ATPase mutants (vma). As vma mutants were also found to show staurosporine-sensitive growth, staurosporine sensitivity is likely to be affected by acidification of the vacuole. Moreover, wild type yeast cells are more sensitive to staurosporine in alkaline media than in acidic media, suggesting that staurosporine is exported from the cytosol by H+/drug antiporters. Pleiotropic drug resistance (PDR) genes also provide some resistance to staurosporine, because Δpdr5, Δsnq2 and Δyor1 strains are more sensitive to staurosporine than the wild-type strain. This suggests that staurosporine is also exported by the ATP-binding cassette (ABC) transporters on the plasma membrane. vma mutants and vps mutants of classes C and D vps are sensitive to hygromycin B and vanadate, while ABC transporter-depleted mutants do not show such sensitivity, indicating that two systems differ in their ability to protect the cell against different types of drug.

    Notes: Abstract  Background and aims: We studied the regeneration potential by measuring induction of DNA polymerases in the remnant rat liver after a partial hepatectomy (PHx) that is maximal but compatible with survival. Methods: The regenerating rat liver was obtained after the 90% PHx. The induction of activities of DNA polymerase α, δ, and ɛ were measured after partial purification. The Ki-67 nuclear antigen was also detected histochemically. These parameters were compared with those after both 30% and 70% PHx. Results: The 90% hepatectomy resulted in the strong inductions of DNA polymerase α, δ, and ɛ, at 48 h after operation, in association with increases in wet weight and total DNA in the remnant liver. The enzyme induction was much higher after 90% PHx than after 30% and 70% hepatectomy, in correlation with the resection volume. At 48 h after 90% hepatectomy, the Ki-67 positive cells increased up to 47.2% of hepatocytes in the remnant liver. Conclusion: The higher induction of replication enzymes by 90% hepatectomy reflects more cells entering mitogenic cell cycle, which supports the fast regeneration of the remnant liver. The number of proliferating hepatocytes is stringently controlled by an unknown mechanism sensing the mass of resected liver parenchyma.
