The purpose of this study was to determine whether low-dose methotrexate pulse therapy, which had recently become important in the treatment of rheumatoid arthritis, was effective for controlling the progression of articular destruction in rats with adjuvant arthritis. Intraperitoneal methotrexate at a dose of 0.05 or 0.1 mg kg?1 twice weekly inhibited inflammation in rats with adjuvant arthritis, as shown by reduction of the hind-paw volume. Methotrexate also inhibited articular destruction, as shown by X-ray findings. Although the mechanisms by which low-dose pulse methotrexate acts on rat adjuvant arthritis are still unclear, our results imply that it might effectively slow the progression of articular destruction in rheumatoid arthritis in man. In addition, assessment of articular destruction in this animal model might be useful when evaluating new treatments for rheumatoid arthritis. 相似文献

We have conducted investigations on the relatinship between gastro-intestinal hormones and the autonomic nervous system. In this paper are described main themes of our investigations where a close association between gastrointestinal hormones and the autonomic nervous system was shown from the functional and morphological points of view.
The "nervism" proposed by Pavlov, where the regulation of various organs in the body was thought to be accomplished wholly by the nervous system was based on the findings on the physiology of the digestive glands. In the meantime, the discovery of secretin from the duodenal mucosa led Bayliss and Starling to propose a chemical co-ordination or a humoral regulatory mechanism in additioin to the nervous system for the regulation of the various organs in the body. It is indeed surprising that the principle of two major regulatory mechanisms in the body was thus developed originally on the basic studies of the exocrine and body was thus developed orginally on the basic studies of the exocrine and endocrine funtion of the digestive system.
Our investigations reported in this paper disclosed the fact that the neural and humoral regulatory mechanisms for gastrointestinal secretions acted not separately but in close association both morphologically and functionally. 相似文献

Clinical features in young adult patients with ischaemic colitis 总被引:3,自引:0,他引:3

The clinical, radiographic and endoscopic findings in 16 patients with ischaemic colitis, all of whom were <45 years of age, were analysed. The clinical features were characterized by an acute onset of abdominal pain and rectal bleeding, and persistent constipation prior to the onset of symptoms. Twelve of the 16 patients did not have any known predisposing factors. Barium enema examination and colonoscopy revealed longitudinal ulcers and oedema of the left side of the colon of these patients. These features were then compared with those found in patients with ischaemic colitis, who were > 70 years of age. Although the clinical symptoms, the site of involvement and the initial radiographic or endoscopic findings were similar between the two groups, the transient form of ischaemic colitis and constipation prior to the onset of symptoms were more frequently present in the young patients than in the old patients. These findings suggest that ischaemic colitis, which is not a rare condition even in young adults, is less severe in young patients than in old patients, and that constipation may be related to the pathogenesis of this disease in young adults. 相似文献

YOSHINORI KAWABATA TAMIKO TAKEMURA AKIRA HEBISAWA YUTAKA SUGITA TAKASHI OGURA SONOKO NAGAI FUMIKAZU SAKAI TETSU KANAUCHI THOMAS V. COLBY THE DESQUAMATIVE INTERSTITIAL PNEUMONIA STUDY GROUP 《Respirology (Carlton, Vic.)》2012,17(8):1214-1221
Background and objective: In some patients, desquamative interstitial pneumonia may progress to lung fibrosis. The aim of this study was to assess the long‐term radiological follow‐up results in patients with desquamative interstitial pneumonia. Methods: Among 75 patients suspected of having desquamative interstitial pneumonia, 31 who fulfilled the criteria were included in this study. Clinical characteristics at presentation, responses to treatment and long‐term follow‐up were evaluated. Results: The 31 patients were predominantly males (94%), and the mean age was 55 years; 93% (28/30) had a history of smoking. The clinical findings included high serum levels of lactate dehydrogenase and immunoglobulin G. Bronchoalveolar lavage (26 patients, 84% of cases) frequently showed an increased percentage of eosinophils (mean 17%). Computed tomography (CT) or high resolution (HR) CT at presentation showed ground glass opacities and/or consolidation in all patients, with one third of patients also showing thin‐walled cysts within the ground glass opacities. There was no honeycombing on CT or HRCT scans at presentation. Corticosteroid therapy was effective early in the course of the disease; long‐term follow‐up (mean 99 months) of 31 patients showed only one death due to progression of the disease, but long‐term follow‐up of 14 patients (mean 125 months) by HRCT showed the development of new thin‐walled cysts and honeycombing in five and lung cancer in four patients, respectively. Conclusions: In a proportion of patients, desquamative interstitial pneumonia may progress to lung fibrosis with honeycombing on HRCT, despite therapy. 相似文献
