One hundred and twenty-six allergic subjects were divided into three groups based on the RAST results for Dermatophagoides pteronyssinus (D.p) and Japanese cedar (J.C.). We compared sex, age of examination for RAST, serum IgE, family history of allergic diseases, prevalence rate of bronchial asthma (BA) and allergic rhinitis (AR), and onset of AR among three groups. No significant difference in the other variables except serum IgE and prevalence rate of BA was found between the group with D.p-positive and J.C.-positive RAST and the group with D.p-positive and J.C.-negative RAST. The group with positive RAST for D.p and J.C. showed lower age of the examination, higher serum IgE, higher incidence of allergic family history, higher prevalence rate of BA, and lower onset age of AR than the group with negative RAST for D.p and positive RAST for J.C. We suggested that in J.C. RAST-positive group there might be two different subgroups distinguished by RAST result for D.p Similar results were obtained from the assessment of RAST for Orchard grass instead of J.C. 相似文献

In the air pouch-type allergic inflammation in rats, we reported that a sustained histamine production in the late phase is induced by a cytokine-like factor, named histamine-production-increasing factor (HPIF) (1). Recently, we found another type of histamine-production-increasing factor in the pouch fluid at the chronic phase of air pouch-type allergic inflammation. Although it did not increase histamine production by itself, it enhanced the HPIF-induced histamine production by rat bone marrow cells. It also increased GM-CSF-induced histamine production. The activity of this factor increased time-dependently from 3 to 7 days after the antigen challenge. Injection of the 5 day pouch fluid sample containing this factor into the pouch 4 h after the antigen challenge increased histamine contents in the pouch fluid at 24 h, indicating that this factor enhances HPIF-induced histamine production in vivo. Biochemical analysis of the 5 day pouch fluid sample indicated that this factor is a heat-labile and trypsin-sensitive protein of which pI value and molecular weight are 7–8 and about 100 kDa, respectively. 相似文献

Visfatin is a newly identified adipocytokine that mimics insulin action. However, the pathophysiological role of visfatin in diabetic patients is not fully understood. The main purpose of this study was to investigate the association of plasma visfatin with endothelial function in patients with type 2 diabetes mellitus. In addition, the relationships of visfatin with oxidative stress, low-grade inflammation, atherosclerosis, adiponectin, plasma renin activity, and aldosterone were also explored, and the effect of pioglitazone on visfatin was examined. Visfatin levels were measured in 80 patients with type 2 diabetes mellitus and in 28 age-matched healthy subjects. Endothelial function was evaluated by using flow-mediated vasodilatation (FMD), oxidative stress was assessed by the level of urinary 8-iso-prostaglandin F2alpha, and atherosclerosis and inflammation were measured by using the intimal-medial complex thickness and the levels of high-sensitivity C-reactive protein and fibrinogen. Pioglitazone was administered for 12 weeks at a dose of 30 mg/d in a further 20 patients with type 2 diabetes mellitus. There was a significant negative correlation between the log10-transformed (log) plasma visfatin concentration and FMD or creatinine clearance (R=-0.2672, P=.0167; R=-0.2750, P=.0136). Log visfatin was also positively correlated with log urinary albumin excretion (R=0.2305, P=.0397). In addition, it was also found that visfatin had a significant negative correlation with plasma aldosterone (R=-0.2432, P=.0297). In stepwise regression analysis, creatinine clearance, log aldosterone, FMD, and sex showed a significant association with log visfatin (P=.0040, P=.0069, P=.0444, and P=.0487, respectively), and log 8-iso-prostaglandin F2alpha showed a tendency for an association (P=.0515). Pioglitazone therapy did not affect the visfatin concentration in the 20 pioglitazone-treated patients with diabetes, although a significant elevation of visfatin was obtained in a subgroup of 11 female patients (P=.0381). In conclusion, the current study showed that visfatin is negatively associated with vascular endothelial function evaluated by FMD and creatinine clearance, and positively associated with log urinary albumin excretion. Visfatin was also negatively correlated with circulating aldosterone. Pioglitazone therapy for 12 weeks did not affect the plasma visfatin concentration significantly in all diabetic patients, but a significant elevation in visfatin was obtained in women only. 相似文献

AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS. 相似文献

The tumor microenvironment (TME) has an important influence on tumor progression. For example, we have discovered that passenger stromal cells are necessary for metastasis. In this report, we describe six different cyan fluorescent protein (CFP) multicolor TME nude mouse models. The six different implantation models were used to image the TME using multiple colors of fluorescent proteins: I) Red fluorescent protein (RFP)- or green fluorescent protein (GFP)-expressing HCT-116 human colon cancer cells were implanted subcutaneously in the CFP-expressing nude mice. CFP stromal elements from the subcutaneous TME were visualized interacting with the RFP- or GFP-expressing tumors. II) RFP-expressing HCT-116 cells were transplanted into the spleen of CFP nude mice, and experimental metastases were then formed in the liver. CFP stromal elements from the liver TME were visualized interacting with the RFP-expressing tumor. III) RFP-expressing HCT-116 cancer cells were transplanted in the tail vein of CFP-expressing nude mice, forming experimental metastases in the lung. CFP stromal elements from the lung were visualized interacting with the RFP-expressing tumor. IV) In order to visualize two different tumors in the TME, GFP-expressing and RFP-expressing HCT-116 cancer cells were co-implanted subcutaneously in CFP-expressing nude mice. A 3-color TME was formed subcutaneously in the CFP mouse, and CFP stromal elements were visualized interacting with the RFP- and GFP-expressing tumors. V) In order to have two different colors of stromal elements, GFP-expressing HCT-116 cells were initially injected subcutaneously in RFP-expressing nude mice. After 14 days, the tumor, which consisted of GFP cancer cells and RFP stromal cells derived from the RFP nude mouse, was harvested and transplanted into the CFP nude mouse. CFP stromal cells invaded the growing transplanted tumor containing GFP cancer cells and RFP stroma. VI) Mouse mammary tumor (MMT) cells expressing GFP in the nucleus and RFP in the cytoplasm were implanted in the spleen of a CFP nude mouse. Cancer cells were imaged in the liver 3 days after cell injection. The dual-color dividing MMT cells and CFP hepatocytes, as well as CFP non-parenchymal cells of the liver were imaged interacting with the 2-color cancer cells. CFP-expressing host cancer-associated fibroblasts (CAFs) were predominantly observed in the TME models developed in the CFP nude mouse. Thus, the CFP nude mouse adds another color to the pallet of the TME, allowing multiple types of color-coded cancer and stromal cells to be imaged simultaneously. The multi-colored models described in this report provide new opportunities to study the cellular interactions in the live primary and metastatic TME. 相似文献

In order to individualize and therefore have more effective treatment for pancreatic cancer, we have developed a multicolor, imageable, orthotopic mouse model for individual patients with pancreatic cancer by passaging their tumors through transgenic nude mice expressing green fluorescent protein (GFP) and red fluorescent protein (RFP). The tumors acquired brightly fluorescent stroma from the transgenic host mice, which was stably associated with the tumors through multiple passages. In the present study, pancreatic cancer patient tumor specimens were initially established in NOD.CB17-Prkdc(scid)/NcrCrl (NOD/SCID) mice. The tumors were then passaged orthotopically into transgenic nude mice ubiquitously expressing GFP and subsequently to nude mice ubiquitously expressing RFP. The tumors, with very bright GFP and RFP stroma, were then orthotopically passaged to non-transgenic nude mice. It was possible to image the brightly fluorescent tumors non-invasively longitudinally as they progressed in the non-transgenic nude mice. This non-invasive imageable tumorgraft model will be valuable to screen for effective treatment options for individual patients with pancreatic cancer, as well as for the discovery of improved agents for this treatment-resistant disease. 相似文献
