Objective and Design: Carboxymethylcellulose (CMC) has been considered to be inert and is commonly used as an additive in medicines, foods and cosmetics. However, we experienced a patient who developed an anaphylactic reaction to CMC after an upper gastrointestinal examination using a barium meal containing CMC. Therefore, we examined the incidence of sensitization by CMC in healthy subjects, and categorized the high risk group prone to developing anaphylactic response to CMC.Methods: An ELISA for detecting CMC-specific IgE antibody was developed using serum from the patient as a positive control. In the ten subjects exhibiting high anti-CMC IgE among 387 normal populations, histamine release from isolated leukocytes was performed.Results: Five of ten subjects with a high IgE titer showed a significant CMC-induced histamine release from leukocyte preparations in vitro as observed in the patient, and were classified as high risk group. There was a correlation between sensitization by CMC and that by Japanese cedar pollen. The incidence of sensitization in females was 2.4 fold higher than that in males.Conclusions: The combination of ELISA and histamine release experiment made it possible to identify the high risk group for developing anaphylactic response. The administration of high dose CMC as a suspending agent in barium sulfate or injectable corticosteroids to this group should be avoided to prevent anaphylactic reactions in the clinic.Received 18 August 2003; returned for revision 29 September 2003; accepted by M.

Summary An intravenous injection of 40 or 65 mg/kg streptozotocin induced not only diabetes but also severe hypertension in rats. Whereas the hyperglycemia developed fully within a few days after the injection of streptozotocin, the hypertension progressively advanced and reached maximum level several weeks after the treatment and lasted more than 20 weeks. Twenty mg/kg streptozotocin did not induce hyperglycemia but significantly increased blood pressure several weeks after the treatment. Arrest of growth, polyuria, glycosuria, hyperlipemia and lenticular cataracts developed in the animals treated with 40 or 65 mg/kg streptozotocin, but in none of the animals treated with 20 mg/kg. In histological examinations in the 24th week after the treatment, degranulation and necrosis in the pancreatic -cells, and vacuolization and deposition of PAS-positive materials in the renal proximal tubules were found in the animals treated with 40 or 65 mg/kg streptozotocin. 相似文献

Summary. We report a case of aplastic anaemia (AA) treated with granulocyte colony-stimulating factor (G-CSF) terminating as acute myeloblastic leukaemia (AML). Because of severe pneumonia, 250 μg of G-CSF was administered for 30d to promote neutrophil recovery. Following G-CSF therapy, myeoblasts appeared, and the diagnosis of AML was then made. The myeloblasts proliferated in response to G-CSF in vitro and in vivo. In AA. development of AML, after treatment with G-CSF is rate. Therefore a careful observation for leukaemic transformation is necessary in long-term administration of G-CSF for AA. 相似文献

Histopathology and quantitative PCR (qPCR) were used to determine the tissue distribution of Neospora caninum in calves at 80 days postinfection. Our findings revealed that the most appropriate brain areas for researching N. caninum pathogenesis were the amygdala and hippocampus for qPCR and the corpus striatum and diencephalon for histopathology. 相似文献

Osteoclasts, bone-resorptive multinucleated cells derived from hematopoietic stem cells, are associated with many bone-related diseases, such as osteoporosis. Osteoclast-targeting small-molecule inhibitors are valuable tools for studying osteoclast biology and for developing antiresorptive agents. Here, we have discovered that methyl-gerfelin (M-GFN), the methyl ester of the natural product gerfelin, suppresses osteoclastogenesis. By using M-GFN-immobilized beads, glyoxalase I (GLO1) was identified as an M-GFN-binding protein. GLO1 knockdown and treatment with an established GLO1 inhibitor in osteoclast progenitor cells interfered with osteoclast generation, suggesting that GLO1 activity is required for osteoclastogenesis. In cells, GLO1 plays a critical role in the detoxification of 2-oxoaldehydes, such as methylglyoxal. M-GFN inhibited the enzymatic activity of GLO1 in vitro and in situ. Furthermore, the cocrystal structure of the GLO1/M-GFN complex revealed the binding mode of M-GFN at the active site of GLO1. These results suggest that M-GFN targets GLO1, resulting in the inhibition of osteoclastogenesis. 相似文献

OBJECTIVE: To determine the prevalence and clinical significance of anti-p53 antibody in patients with systemic sclerosis (SSc). METHODS: Anti-p53 antibody was examined by ELISA and immunoblotting. Findings were correlated with clinical features of disease and other autoantibodies and compared with other connective tissue diseases as well as normal controls. p53 activity to bind target DNA was evaluated by ELISA using a plate coated with oligonucleotide containing the consensus binding site for p53. RESULTS: IgG anti-p53 antibody levels were elevated in patients with SSc compared to patients with systemic lupus erythematosus (n = 20; p < 0.05), dermatomyositis (n = 21; p < 0.005), atopic dermatitis (n = 17; p < 0.0005), or bullous pemphigoid (n = 10; p < 0.0005) and normal controls (n = 21; p < 0.0005). Remarkably, anti-p53 antibody levels were higher in patients with limited cutaneous SSc (lSSc; n = 30) than those found in patients with diffuse cutaneous SSc (dSSc; n = 40; p < 0.05). IgG or IgM anti-p53 antibody levels did not correlate with the presence or levels of other autoantibodies. IgG anti-p53 antibody was associated with longer disease duration (p < 0.05) and decreased percentage vital capacity (p < 0.05), and correlated negatively with modified Rodnan total skin thickness score (r = -0.352, p < 0.01). Immunoblotting analysis confirmed the presence of IgG anti-p53 antibody in selected patients with SSc. IgG isolated from sera of selected patients with SSc that contained IgG anti-p53 antibody inhibited the p53 activity relative to normal controls. CONCLUSION: IgG anti-p53 antibody was detected in lSSc and dSSc, and was more prominent in lSSc, indicating that IgG anti-p53 antibody is a novel autoantibody associated with lSSc, a milder form of SSc. 相似文献

Background
Early (≤24 h) systemic procalcitonin (PCT) levels are predictive for unfavorable neurological outcome in patients after out-of-hospital cardiac arrest (OHCA). Subarachnoid hemorrhage (SAH) due to aneurysm rupture might lead to a cerebral perfusion stop similar to OHCA. The current study analyzed the association of early PCT levels and outcome in patients after SAH.Methods
Data from 109 consecutive patients, admitted within 24 h after SAH, were analyzed. PCT levels were measured within 24 h after ictus. Clinical severity was determined using the World Federation of Neurological Societies (WFNS) scale and dichotomized into severe (grade 4–5) and non-severe (1–3). Neurological outcome after 3 months was assessed by the Glasgow outcome scale and dichotomized into unfavorable (1–3) and favorable (4–5). The predictive value was assessed using receiver operating curve (ROC) analysis.Results
Systemic PCT levels were significantly higher in patients with severe SAH compared to those with non-severe SAH: 0.06 ± 0.04 versus 0.11 ± 0.11 μg/l (median ± interquartile range; p < 0.01). Patients with unfavorable outcome had significantly higher PCT levels compared to those with favorable outcome 0.09 ± 0.13 versus 0.07 ± 0.15 ng/ml (p < 0.01). ROC analysis showed an area under the curve of 0.66 (p < 0.01) for PCT, which was significantly lower than that of WFNS with 0.83 (p < 0.01).Conclusions
Early PCT levels in patients with SAH might reflect the severity of the overall initial stress response. However, the predictive value is poor, especially compared to the reported predictive values in patients with OHCA. Early PCT levels might be of little use in predicting neurological outcome after SAH. 相似文献10.
