We tested the ability of Escherichia coli lipopolysaccharide (LPS) to phase-shift the activity circadian rhythm in C57Bl/6J mice. Intraperitoneal administration of 25 μg/kg LPS induced photic-like phase delays (−43±10 min) during the early subjective night. These delays were non-additive to those induced by light at CT 15, and were reduced by the previous administration of sulfasalazine, a NF-κB activation inhibitor. At CT 15, LPS induced c-Fos expression in the dorsal area of the suprachiasmatic nuclei (SCN). Our results suggest that the activation of the immune system should be considered an entraining signal for the murine circadian clock.  相似文献

Clinical features and management of Crohn’s disease in Chinese patients   总被引:8,自引:0,他引:8  
Background An increasing incidence of Crohn‘s disease has been found in China in recent years.Our study has been focused on evaluating the diversity of the clinical manifestations of Crohn‘ s disease in order to improve early diagnostic accuracy and therapeutic efficacy.Methods Thirty patients with active Crohn‘s disease were enrolled and their clinical data, including diagnostic and therapeutic results, were analyzed. Endoscopy combined with histological examination of biopsy specimens provided characteristic features of the disease. Transabdominal bowel sonography (TABS) was used for detecting intestinal complications. Nutritional supportive therapy was given to 20 subjects with active cases of the disease.Results Most patients were young adults with a higher proportion of females to males ( ratio: 1.14:1 ). The disease affects any segment or a combination of segments along with the alimentary tract(from the mouth to the anus). In this study, the colon and small bowel were the major sites involved.Recurrent episodes of abdominal pain in the right lower quadrant and watery diarrhea were the most common symptoms. Granulomas were identifiable in nearly one-third (30. 8%) of all biopsy specimens. In moderate cases of the disease, remission was achieved more quickly through the use of oral prednisone therapy than with SASP or 5-ASA. Beneficial effects on the host‘ s nutritional status were observed. Immunosuppressives were used on an individual basis and showed variable therapeutic effects. Sixteen patients had surgery due to intestinal obstruction or failure to respond to drug therapies. Rapid improvement after surgery was reported.Conclusion Endoscopy (with biopsy) and TABS were both crucial procedures for diagnosis. SASP (or 5-ASA) and prednisone were effective as inductive therapies. Azathioprine has demonstrable benefits after induction therapy with prednisone. Surgery, as an alternative treatment, provided another effective choice in selected patients.  相似文献

目的:选择合适的大鼠炎性肠病(IBD)模型,观察中药灌肠Ⅰ号对其治疗作用,为IBD治疗寻找新途径。方法:Wistar大鼠80只,分为正常对照组、模型组、西药sulfasalazine(SASP)组和中药灌肠Ⅰ号组,每组动物20只。分别在用药后4,7,14,21 d观察外周血细胞变化与肠道病理学指标。结果:给药7 d后SASP组和中药组外周血小板数都比模型对照组明显升高。组织病理学观察显示SASP组对于IBD的远期治疗作用不甚明显,而灌肠Ⅰ号确实有减轻IBD病变,促进其修复的作用,近期与SASP相当,远期优于SASP。结论:中药灌肠Ⅰ号有较明显的抗大鼠炎性肠病效果。  相似文献

The 1990's have brought a significant promise and the hope for a better and brighter future in the new millennium for patients with inflammatory bowel disease (I3D). A better understanding of the pathophysiology of IBD symptoms has led to newer treatnent modalities and streamlining of therapy for specific subsets of patients. ULCERATIVE COUTISThe treatnent for ulcerative colitis (UC) is aimed at modulating the inflammatory response. The drugs which are found to be effective are sulfasalazine (Azulfidine, Salazopyrin) and its 5ASA derivatives, glucocorticosteroids, immunomodulators/immunosuppressants, and other new potential drugs (Table 1).  相似文献

Our purpose was to study the effects of long-term salazopyrine treatment on male fertility. Seven patients, 21-37 years old, who had been treated for ulcerative colitis with 3 g/day of salazopyrine for more than 6 months, were examined. All their semen samples showed abnormal sperm motility (17% +/- 9.3) and abnormal morphology (36.3% +/- 14.4) with the predominance of large-headed spermatozoa. The endocrine picture and pituitary reserve were evaluated by GnRH and TRH tests. The basal values of testosterone were lower than the normal in our laboratory (greater than 3 ng/ml) and significantly lower (2.4 +/- 0.7 ng/ml, p less than 0.025) than in the control group (fertile men). LH was significantly higher (9 +/- 2 mIU/ml, p less than 0.005) but still within the limits of normal. The responses of FSH and LH to GnRH and of PRL to TRH were normal. The mechanisms by which salazopyrine may affect fertility are discussed.  相似文献

A 56-year-old man presented with a 4-month history of a painful and pruritic eruption consisting of crusted plaques and blisters on his face, scalp and chest. The patient suffered from headaches and malaise but was afebrile. Two skin biopsies revealed an epidermis which was eroded and covered by locules of serum and neutrophils. In the underlying dermis, there was a marked mixed inflammatory reaction including lymphocytes, neutrophils and numerous eosinophils. There was exocytosis of eosinophils into several follicles with areas of follicular mucinosis. A diagnosis of necrotizing eosinophilic folliculitis was made based upon the clinical and histopathological findings. The diagnosis was supported by the rapid response to a combination of indomethacin and cephalexin. The patient has taken continuous indomethacin (with rabeprazole and misoprostol cover) and cephalexin for 2 years. If treatment is withdrawn he experiences a flare of his disease within 2 weeks. This case highlights the potentially chronic nature of this disease.  相似文献
