Molecular forms of plasma and urinary adrenomedullin in normal, essential hypertension and chronic renal failure.

OBJECTIVES: Human adrenomedullin precursor is converted to glycine-extended adrenomedullin (AM-Gly), an intermediate inactive form of adrenomedullin. Subsequently, AM-Gly is converted to active form of mature adrenomedullin (AM-m). The aim of the present study was to investigate (i) whether sex or age influences plasma and urinary AM-m and AM-Gly levels in normal subjects; (ii) the daytime variability of plasma AM-m and AM-Gly levels in normal subjects; (iii) AM-m and AM-Gly levels and its ratio in plasma and urine in normal subjects, individuals with essential hypertension (HT), and chronic renal failure (CRF); and (iv) the ratio of AM-m and AM-total (T) in plasma of various veins and aorta. METHODS: We measured plasma levels and urinary excretions of AM-m, AM-Gly and AM-T (AM-m + AM-Gly) by recently developed immunoradiometric assay in normal subjects (n = 81), HT (n = 28) and CRF (n = 30). We also determined the molecular forms of plasma adrenomedullin taken from various sites during angiography in patients with suspected renovascular hypertension (n = 9). RESULTS: There were no differences in plasma and urinary excretions of two molecular forms of adrenomedullin among sexes or ages in normal subjects. There was no daytime variation of plasma two molecular forms of adrenomedullin in normal subjects. Plasma AM-m, AM-Gly and AM-T levels were increased in patients with HT and CRF compared with normal subjects, whereas urinary AM-m, AM-Gly and AM-T excretions were decreased in patients with HT and CRF compared with normal subjects. Urinary AM-m: AM-T ratios were significantly higher than plasma AM-m: AM-T ratios. Plasma AM-m and AM-T levels taken from various veins were similar, and they were significantly higher than those of aorta, although there were no differences in plasma AM-Gly levels between aorta and veins. CONCLUSIONS: These results suggest that in normal subjects, and individuals with HT and CRF: (i) plasma and urinary excretions of AM-m and AM-Gly are not affected by age or sex; (ii) AM-m in parallel with AM-Gly is increased; (iii) urine contains a higher percentage of active adrenomedullin than plasma; and (iv) plasma AM-m may be partly metabolized in the lung.

Proteolytic cleavage of staphylococcal exoproteins analyzed by two-dimensional gel electrophoresis.

Extracellular proteases of Staphylococcus aureus are emerging as potential virulence factors that are relevant to the pathogenicity of staphylococcal infections. These proteases may also be involved in the proteolytic cleavage of other exoproteins released from this organism. To define the target exoproteins and their sites of cleavage by proteases, high-resolution two-dimensional polyacrylamide gel electrophoresis followed by N-terminal amino acid sequencing of exoprotein spots was performed. Two to three hundred exoprotein spots were detected at the early-stationary phase of cultures of S. aureus NCTC8325, and then at the late-stationary stage most of these high molecular protein spots became invisible due to further proteolytic degradation. As the result of N-terminal analysis, lipase, triacylglycerol lipase, orf619 protein and orf388 protein were detected as multiple spots at the early-stationary phase. We found that these exoproteins were cleaved at 3, 7, 4 and 4 different sites, respectively, by proteases. According to the M.W. and pI of each peptide spot obtained from the gel and their matches with calculated values in addition to their N-terminal sequences, we showed that the positions of putative peptides resulted from proteolytic cleavage of these proteins.

The production and clinical evaluation of macrophage colony-stimulating factor and macrophage chemoattractant protein-1 in human follicular fluids.

PROBLEM: In order to investigate the role of macrophage colony-stimulating factor (M-CSF) and macrophage chemoattractant protein-1 (MCP-1) in human ovulation, we measured the concentrations of M-CSF and MCP-1 in human follicular fluids (FFs) and correlated them with oocyte maturation. METHOD OF STUDY: The oocytes were obtained from the FFs of 46 women undergoing in vitro fertilization and embryo transfer (IVF ET). The concentrations of M-CSF and MCP-1 in the FFs were measured by enzyme-linked immunosorbent assay. In addition, granulosa cells obtained from the FFs of IVF patients were cultured and treated with forskolin and 12-O-tetradecanoylphorbol 13-acetate (TPA) for 24 48 hr. RESULTS: Concentrations of M-CSF and MCP-1 were significantly higher in the FFs than in the serum (P < 0.01). M-CSF concentrations tended to be higher, while MCP-1 concentrations were significantly higher in the FFs containing mature oocytes than in FFs containing immature oocytes (P < 0.05). The production of M-CSF was markedly increased over the basal level after treatment with forskolin (10 microM) for 24 (P < 0.02) and 48 hr (P < 0.01); however, the production of MCP-1 was unchanged. CONCLUSIONS: Our data suggest that M-CSF and MCP-1 may play an important role in human preovulatory processes and that M-CSF, in particular, may be regulated by cyclic adenosine monophosphate. M-CSF and MCP-1 may also be valuable biochemical markers in the evaluation of oocyte maturation.

ST segment elevation in the right precordial leads following administration of class Ic antiarrhythmic drugs.

Electrocardiographic changes were evaluated retrospectively in five patients without previous episodes of syncope or ventricular fibrillation who developed abnormal ST segment elevation mimicking the Brugada syndrome in leads V1-V3 after the administration of class Ic antiarrhythmic drugs. Pilsicainide (four patients) or flecainide (one patient) were administered orally for the treatment of symptomatic paroxysmal atrial fibrillation or premature atrial contractions. The QRS duration, QTc, and JT intervals on 12 lead surface ECG before administration of these drugs were all within normal range. After administration of the drugs, coved-type ST segment elevation in the right precordial leads was observed with mild QRS prolongation, but there were no apparent changes in JT intervals. No serious arrhythmias were observed during the follow up periods. Since ST segment elevation with mild QRS prolongation was observed with both pilsicainide and flecainide, strong sodium channel blocking effects in the depolarisation may have been the main factors responsible for the ECG changes. As the relation between ST segment elevation and the incidence of serious arrhythmias has not yet been sufficiently clarified, electrocardiographic changes should be closely monitored whenever class Ic drugs are given.

Evidence against high glucose as a mediator of ERK1/2 or p38 MAPK phosphorylation in rat skeletal muscle.

Hyperglycemia leads to multiple changes in insulin signaling in skeletal muscle from people with type 2 diabetes. We hypothesized that mitogen-activated protein kinase (MAPK) signaling cascades may be directly activated by an acute exposure to high extracellular glucose concentrations. We determined whether an elevation in the extracellular glucose concentration would induce signal transduction in skeletal muscle via MAPK cascades. Epitrochlearis muscles were incubated in the presence of 5 or 25 mM glucose. Exposure of muscle to either hyperosmosis (600 mM mannitol) or insulin (6 nM) led to a marked increase in extracellular signal-regulated protein kinase (ERK)1/2 phosphorylation. Hyperosmosis elicited a 5.2-fold increase in p38 phosphorylation (P < 0.05), whereas insulin was without effect. ERK1/2 phosphorylation was not increased by high glucose exposure. After a 20-min exposure to 25 mM glucose, a tendency toward repressed (23%) p38 phosphorylation was observed (P = 0.06). No effect of high glucose was noted on signal transduction to signal transducer and activator of transcription 3 and Akt. In conclusion, short-term exposure of skeletal muscle to high levels of glucose does not appear to alter ERK1/2 or p38 MAPK phosphorylation.

Pregnancy outcome in nephrotic syndrome with mixed connective tissue disease.

We describe two pregnancies of a young woman with mixed connective tissue disease. In June 1983, she was diagnosed as having Raynaud's phenomenon, arthralgia, and proteinuria. She then developed nephrotic syndrome. Methylprednisolone was initially prescribed at a large dose of 1 g/day which was slowly tapered to 5 mg/day. The proteinuria disappeared. During both pregnancies (the first beginning in December 1988 and the second in May 1992), the patient was placed on a prednisolone maintenance dose (5 mg/day). Both neonates were born healthy at term with no complications. Continuing prednisolone may be useful in pregnant women, and aggressive treatment to prevent mixed connective tissue disease exacerbation may be appropriate during pregnancy.

Expression and function of peroxisome proliferator-activated receptor-gamma in mesangial cells.

P:eroxisome proliferator-activated receptor-gamma (PPARgamma) is a novel nuclear receptor, which enhances insulin-mediated glucose uptake. Ligands to PPARgamma are currently used as therapy for type II diabetes. Using Western blot analysis, RNase protection assay, and immunostaining, we identified the presence of PPARgamma message and protein in cultured primary rat mesangial cells. Electrophoretic mobility of a labeled PPARgamma response element (PPRE) was retarded in the presence of mesangial cell nuclear extract, suggesting that PPARgamma is functional in these cells. The addition of unlabeled PPRE efficiently competed away the PPARgamma-PPRE protein complex, confirming specificity of binding of the PPARgamma to the PPRE. PPARgamma ligands rosiglitazone (1 to 10 micromol/L) and troglitazone (1 to 10 micromol/L) inhibited platelet-derived growth factor-induced DNA synthesis, measured as bromodeoxyuridine incorporation (P<0.01). This inhibition was dose dependent. When administered in antidiabetic doses to streptozotocin-induced diabetic rats, troglitazone substantially normalized albumin excretion at 3 months (from 687.1 to 137.6 microgram urinary albumin/mg creatinine, P:<0.05) but did not affect hyperglycemia or blood pressure in this model. This treatment also decreased glomerular plasminogen activator inhibitor-1 (PAI-1) expression. These data suggest that PPARgamma activation may directly attenuate diabetic glomerular disease, possibly by inhibiting mesangial growth, which occurs early in the process of diabetic nephropathy, or by inhibiting PAI-1 expression. PAI-1 inhibits the activation of plasmin and matrix metalloproteinase, which degrade extracellular matrix in the glomerulus. Excess glomerular PAI-1 allows the accumulation of extracellular matrix, leading to glomerulosclerosis. These results have therapeutic implications for diabetic nephropathy as well as for proliferative mesangial diseases of the kidney.

Recurrence of myocarditis presenting as pacing and sensing failure after implantation of a permanent pacemaker at first onset.

A 31-year-old woman was admitted to hospital with loss of consciousness and generalized convulsions. Electrocardiography (ECG) showed complete atrioventricular block (AV block) with a pulse rate of 30 beats/min. Endomyocardial biopsy from the right ventricle showed massive necrosis and degeneration of myocardial cells with extensive infiltration of lymphocytes into the interstitial space. These pathological findings suggested fulminant myocarditis. Following glucocorticoid therapy, the patient became asymptomatic, but the AV block did not resolve completely and a bifocal pacemaker was implanted. However, similar symptoms recurred 7 years later. An ECG showed pacing and sensing failure linked to an increase in the pacing threshold and a decrease in the sensing threshold. Endomyocardial biopsy from the right ventricle again showed interstitial infiltration with lymphocytes and eosinophils. After glucocorticoid therapy, she became asymptomatic once more, and the improvement in the pacing and sensing failure, and cardiomegaly, was satisfactory. This patient represents a very rare case of recurrence of acute myocarditis without progression, as much as 7 years after its first occurrence. Glucocorticoid therapy was still effective in treating the recurrent myocarditis presenting with pacing and sensing failure.

Immigrants' welfare use and opportunity for contact with co-ethnics.

In this article we examine the relationship between immigrants' welfare use and their social capital, using the 1990 census. We measure community social capital using contact with co-ethnics and co-ethnics' economic inactivity, and examine the use of AFDC and SSI in two subpopulations: single-mother families and elderly units. Major findings are that the effects of social capital differ between immigrant single-mother families and elderly units; the effects of social capital differ between the young-at-arrival elderly and the old-at-arrival elderly; and the process of AFDC use is similar for immigrants and for natives, whereas the process of SSI use is more complicated for immigrants than for natives.

The exact expression of glial fibrillary acidic protein (GFAP) in trigeminal ganglion and dental pulp.

The expression in various cell types of peripheral tissues of glial fibrillary acidic protein (GFAP), first discovered as an intermediate filament specific for astrocytes, remains controversial owing to numerous reports of a wide distribution for GFAP-immunoreactivity in various cells. The present study employed immunohistochemistry to investigate the precise expression of GFAP in the dental pulp and trigeminal ganglion of adult rats and wild-type mice as well as GFAP-knockout mice. The exhibition of GFAP-immunoreactivity in the trigeminal ganglion was further examined by a reverse transcription polymerase chain reaction (RT-PCR) technique, and in situ hybridization histochemistry using a specific cRNA probe prepared by us. The immunoreaction for GFAP was recognizable in the axons, Schwann cells, and the fibroblasts in the dental pulp of rats and wild-type littermate mice. However, mice with null mutations in the GFAP gene remained immunoreactive for GFAP in all these locations. Intense GFAP-immunoreactivity was found in a small number of satellite cells in the trigeminal ganglion in all animals examined in this study. RT-PCR analysis demonstrated bands for the GFAP gene corresponding to the length expected from the primer design in the samples of trigeminal ganglion and dental pulp. In situ hybridization histochemistry also showed intense signals for GFAP mRNA in some satellite cells of the trigeminal ganglion, but never in the neurons. These data suggest that the GFAP-immunoreactive molecules in the pulpal axons and fibroblasts react non-specifically with the polyclonal antibody and are probably a closely related type of intermediate filament.

Treatment of glioblastoma by direct inoculation of concentrated high titer-recombinant retrovirus carrying the herpes simplex virus thymidine kinase gene.

We prepared retroviruses carrying the lacZ gene or herpes simplex virus thymidine kinase (HTK) gene with titers of 1.4-2.5 x 10(11) colony-forming units (cfu)/ml, and stereotaxically inoculated only 3 microliters of the retroviruses into a mouse glioma model. This resulted in highly efficient transduction in vivo. The transduced glioma cells migrated far from the implantation site, potentiating the induction of the remarkable bystander effect. Following repetitive ganciclovir (GCV) intraperitoneal injection, effective killing of glioma cells in the mouse brain was observed. The transduction efficiency was nearly as high as that observed for the implantation of high-titer retrovirus-producing fibroblasts. Eighty per cent of brain tumor-bearing mice were completely cured by our treatment protocol using concentrated HTK-harboring retroviruses. Our results suggest that repeated inoculations of high-titer retroviruses carrying the HTK gene followed by GCV treatment may be a promising strategy for the clinical treatment of malignant gliomas. To achieve further safety in the gene therapy of glioma, genes abundantly expressed in human glioblastoma were searched by the Serial Analysis of Gene Expression (SAGE) technique. Among the top-147 most expressed tags in glioblastoma, we found a tag, TTTTGGGTAT, originated from an unidentified gene, which was not detected in human astrocyte cultures. Real-time quantitative RT-PCR showed that MAGE-E1 expression was 2.6-15 fold enriched in glioblastoma relative to human astrocytes. Expressed Sequence Tags (ESTs) containing this tag were homologous to melanoma-associated antigen gene (MAGE) family, and this new cDNA, named MAGE-E1, was cloned by 5'-rapid amplification of cDNA ends (RACE) technique. MAGE-E1 expression was enriched in glioblastoma and low in other cancers, and MAGE-E1 expression was detected only in brain and ovary among normal tissues. These results indicate that MAGE-E1 is a novel and glioma-specific member of MAGE family, which can be applied to glioma-specific gene transduction.

Early full donor myeloid chimerism after reduced-intensity stem cell transplantation using a combination of fludarabine and busulfan.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate lineage-specific chimerism reconstitution after reduced-intensity allogeneic stem cell transplantation (RIST) using a combination of fludarabine (30 mg/m2 for 6 days) and busulfan (4 mg/kg for 2 days). DESIGN AND METHODS: We prospectively enrolled 8 consecutive patients with hematologic malignancies who were not candidates for conventional transplantation because of either high age or organ dysfunction. Host-donor chimerism was evaluated using polymerase chain reaction-based amplification of a polymorphic short tandem repeat region. RESULTS: All of our patients achieved engraftment within a median of 11 days after transplantation. On day 30, full donor myeloid cell chimerism (>90%) was achieved in 7 patients whereas full donor T-cell chimerism was achieved in only one patient. Thus, in contrast to other reported results, full donor chimerism was achieved earlier in the myeloid lineage than the T-cell lineage. On day 60, however, T-cell chimerism caught up with myeloid chimerism. Two patients developed grade II-IV acute graft-versus-host disease (GVHD) before the detection of full donor T-cell chimerism. INTERPRETATION AND CONCLUSIONS: Our findings suggest that the kinetics of lineage-specific chimerism depend on the agents used in the conditioning regimen, and may provide insight into the chimerism kinetics and pathogenesis of GVHD. Thus, the strategy for controlling immunosuppression after RIST should be modified according to the type of conditioning regimen applied.

Inverse correlation between macrophage-colony stimulating factor, cholesterol and high density lipoprotein cholesterol in Kawasaki disease.

Kawasaki disease (KD) is a childhood-onset vascular disease. We assessed the concentrations of macrophage-colony stimulating factor (M-CSF) and those of lipids in sera from patients with KD. The M-CSF concentration in patients with acute-phase KD was 2,914+/-159 U/ml, significantly higher than that in control subjects with Infectious diseases (1,241+/-96 U/ml). The elevated levels of this cytokine in the acute phase fell to 1,319+/-138 U/ml in the convalescent phase. Total and high-density lipoprotein cholesterol concentrations in acute phase KD (113.8+/-8.4 and 21.5+/-2.3 mg/dl, respectively) were lower than in the infectious disease controls (195.8+/-7.0 and 62.5+/-1.8 mg/dl). The elevation of M-CSF correlated with the decrease of total and high-density lipoprotein cholesterol. Overproduction of macrophage-colony stimulating factor activates macrophages and monocytes and may disturb the lipid metabolism. Both effects could contribute to vasculitis in KD.

Evaluation of angiogenesis in non-small cell lung cancer: comparison between anti-CD34 antibody and anti-CD105 antibody.

PURPOSE: Angiogenesis is an essential process in the progression of malignant tumors. Whereas pan-endothelial markers, such as CD34, are generally used in evaluation of angiogenesis, pan-endothelial antibodies react with not only "newly forming" vessels but also normal vessels just trapped within tumor tissues. It has been recently reported that anti-CD105 antibody preferentially reacts with "activated" endothelial cells in angiogenic tissues. Thus, the superiority of anti-CD105 monoclonal antibody (mAb) in evaluation of angiogenesis of non-small cell lung cancer (NSCLC) was assessed. EXPERIMENTAL DESIGN: A total of 236 patients with resected NSCLC were retrospectively reviewed. Intratumoral microvessel density (IMVD) was determined with an anti-CD34 mAb (CD34-IMVD) and with an anti-CD105 mAb (CD105-IMVD). RESULTS: The mean CD34-IMVD and CD105-IMVD were 179.9 and 41.6, respectively. Whereas CD34-IMVD was significantly correlated with the expression of vascular endothelial growth factor (P = 0.003), CD105-IMVD was more closely correlated with vascular endothelial growth factor expression (P < 0.001). The 5-year survival rate of the lower CD105-IMVD patients was 74.9%, significantly higher than that of the higher CD105-IMD patients (60.4%, P = 0.018). Whereas the 5-year survival rate of the lower CD34-IMVD patients seemed higher than that of the higher CD34-IMVD patients (63.7%), the difference did not reach a statistical significance (P = 0.137). Multivariate analysis confirmed that higher CD105-IMVD was a significant factor to predict poor prognosis (P = 0.029), whereas CD34-IMVD was not (P = 0.070). CONCLUSIONS: Anti-CD105 mAb proved to be superior to anti-CD34 mAb in evaluation of angiogenesis in NSCLC.

Fatal buckwheat dependent exercised-induced anaphylaxis.

Cases of food-dependent exercise-induced anaphylaxis (FEA) caused by buckwheat have been rare. Clinical, laboratory, and autopsy findings are present on an 8-year old girl with FEA caused by Japanese buckwheat. The patient consumed buckwheat noodles called "zaru soba" and immediately thereafter swam vigorously. Approximately 30 minutes later, she complained of abdominal pain, vomiting, coughing, and chest discomfort. Another ten minutes later her consciousness level deteriorated and she experienced cardiorespiratory arrest. The heart beat was restored and she was admitted to the hospital. She never regained consciousness and expired after another arrest 13 days later. Her IgE level was high (2,840 IU/ml) and the IgE-radioallergosorbent test (RAST) score was 2 for soybeans, 3 for buckwheat, 2 for rice, and 3 for wheat. An exaggerated hematemesis that occurred immediately after hospital admission indicated an inflammatory condition of the digestive tract that was caused by buckwheat. Marked ulceration accompanied with hemorrhage and necrosis was noted at the ileum. Extensive hemorrhage involving the endotracheal pulmonary field and lymphocyte infiltration of the alveolar space likely appeared after the inflammation. The analysis of buckwheat-specific IgE antibody by immunoblotting showed 7 bands that reacted with the IgE of the patient's serum, 4 bands: 16, 20, 24, and 58 kDa, were specific to the patient as compared to subjects not allergic to buckwheat. A first case of fatal FEA by buckwheat is reported with reference to specific IgE.

Ras oncoprotein induces CD44 cleavage through phosphoinositide 3-OH kinase and the rho family of small G proteins.

CD44 is a cell surface adhesion molecule for several extracellular matrix components. We previously showed that CD44 expressed in cancer cells is proteolytically cleaved at the ectodomain through membrane-anchored metalloproteases and that CD44 cleavage plays a critical role in cancer cell migration. Therefore, cellular signals that promote the migration and metastatic activity of cancer cells may regulate the CD44 ectodomain cleavage. Here, we demonstrate that the expression of the dominant active mutant of Ha-Ras (Ha-Ras(Val-12)) induces redistribution of CD44 to the newly generated membrane ruffling area and CD44 ectodomain cleavage. The migration assay revealed that the CD44 cleavage contributes to the Ha-Ras(Val-12)-induced migration of NIH3T3 cells on hyaluronate substrate. Treatment with LY294002, an inhibitor for phosphoinositide 3-OH kinase (PI3K), significantly inhibits Ha-Ras(Val-12)-induced CD44 cleavage, whereas that with PD98059, an inhibitor for MEK, does not. The active mutant p110 subunit of PI3K has also been shown to enhance the CD44 cleavage, suggesting that PI3K mediates the Ras-induced CD44 cleavage. Moreover, the expression of dominant negative mutants of Cdc42 and Rac1 inhibits the Ha-Ras(Val-12)-induced CD44 cleavage. These results suggest that Ras > PI3K > Cdc42/Rac1 pathway plays an important role in CD44 cleavage and may provide a novel molecular basis to explain how the activated Ras facilitates cancer cell migration.

Flow cytometric differentiation of Asian and Western types of multiple sclerosis, HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and hyperIgEaemic myelitis by analyses of memory CD4 positive T cell subsets and NK cell subsets.

We examined the alterations of memory CD4(+) T cell subsets bearing surface receptors linked to either Th1 or Th2 cytokine production as well as natural killer (NK) cell subsets by three color flow cytometry in the peripheral blood from 36 patients with clinically definite multiple sclerosis (MS), 27 patients with HAM/TSP, 13 patients with hyperIgEaemic myelitis who had mite antigen-specific IgE and 25 healthy controls (HC). The patients with MS were clinically classified into an optico-spinal form of MS (Asian type, MS-A) and the conventional form of MS (Western type, MS-W). MS-A showed a significant increase of CD4(+)CD45RA(-)CCR5(+) cells (Th1 cells) through the relapse and remission phases in comparison to HC, while MS-W showed a significant increase of CD4(+)CD45RO(+)CD62L(-) cells (Th1 cells) only at the relapse phase. HAM/TSP showed a significant increase of CCR5(+) and CD62L(-) memory CD4(+) T cells as well as CD30(+) memory CD4(+) T cells (Th2 cells) in comparison to HC. On the other hand, a selective increase of CD4(+)CD45RO(+)CD30(+) cells was found in hyperIgEaemic myelitis. The percentage of mature NK cells (CD3(-)CD16(+)CD56(+) cells) as well as double negative T cells (CD3(+)CD4(-)CD8(-) cells) decreased significantly in HAM/TSP in comparison to HC. Our findings therefore suggest a flow cytometric analysis of Th1/Th2-associated markers on memory CD4(+) T cells as well as NK cell subsets to be useful for differentiating various inflammatory neurologic conditions.
