Purpose: The localization of dopamine D| receptors (DIR) in the chicken retina was examined using an anti-human DI R. monoclonal antibody and PAP techniques. Results: A clear band of staining was seen in the outer plex-iform layer; as well as cellular staining in the outer-most part of the inner nuclear layer probably in a subset of horizontal cells. Many different amacrine cell bodies were labelled in the inner one-third of the inner nuclear layer. There was also extensive staining in the inner plexiform layer; which showed some striation. Occasional labelled ganglion cells were also detected. Conclusion: Localization of DI-dopamine receptors has 相似文献

There appears to be a fundamental step-transition in retinal function at low light intensities, close to the scotopic-mesopic transition. This step-transition is observed for elements of the retinal dark-light switch, which has been described in the chicken retina. Over the same range of light intensities, there is a step-transition in photoreceptor retinomotor movements and in the coupling of horizontal and All amacrine cells, which suggests a switch in retinal circuitry from rod-processing to cone-processing regimes. A similar step-transition in pineal function suggests that the retinal step-transition signals to the central circadian systems. Finally, this step-transition may also inhibit eye growth, and thus be responsible for the reported diurnal rhythm in eye growth. Disturbances to this step-transition may be the initial cause of disordered eye growth in the form-deprivation myopia paradigm. 相似文献

Background and Purpose
The discovery of DP2 as a second receptor for PGD2 has prompted the search for antagonists as potential novel therapies based on the associations between PGD2 and disease. Here we describe the biochemical and pharmacological properties of 4-(acetylamino)-3-[(4-chlorophenyl)thio]-2-methyl-1H-indole-1-acetic acid (AZD1981), a novel DP2 receptor antagonist.Experimental Approach
Binding to DP2, functional receptor pharmacology and selectivity were studied in both human and animal systems.Key Results
AZD1981 displaced radio-labelled PGD2 from human recombinant DP2 with high potency (pIC50 = 8.4). Binding was reversible, non-competitive and highly selective against a panel of more than 340 other enzymes and receptors, including DP1 (>1000-fold selective). AZD1981 inhibited DP2-mediated shape change and CD11b up-regulation in human eosinophils, shape change in basophils and chemotaxis of human eosinophils and Th2 cells with similar potency. AZD1981 exhibited good cross-species binding activity against mouse, rat, guinea pig, rabbit and dog DP2. Evaluation in mouse, rat or rabbit cell systems was not possible as they did not respond to DP2 agonists. Agonist responses were seen in guinea pig and dog, and AZD1981 blocked DP2-mediated eosinophil shape change. Such responses were more robust in the guinea pig, where AZD1981 also blocked DP2-dependent eosinophil emigration from bone marrow.Conclusions and Implications
AZD1981 is a DP2 antagonist that blocks functional responses in eosinophils, Th2 cells and basophils. It exhibited similar potency irrespective of the cell type, DP2 agonist or species used. This selective orally active agent is currently under clinical evaluation as a potential therapeutic agent in respiratory diseases including asthma. 相似文献49.

结节病是一种罕见的和潜在的致残儿科疾病。此病临床治疗困难,需要长期监测。我们报告了1例9岁的白人女孩的情况,就诊最初表现为双侧慢性前葡萄膜炎、白内障和继发于结节病的青光眼。在过去的2a,患者接受左布诺洛尔滴剂,局部和全身类固醇治疗,随后要求折叠式人工晶状体植入。在白内障手术后的2mo,患者葡萄膜炎以局部类固醇和低剂量甲氨蝶呤一直控制良好。她全血计数和肾功能定期监测,没有甲氨蝶呤不良影响的报告。结节病是一多系统疾病,需要眼科学家,神经学家和儿科医师多学科的投入。内科和外科治疗本病富于挑战。本例强调了低剂量甲氨蝶呤在儿童慢性葡萄膜炎治疗中的安全性和对此病及时治疗以防止显著发病的需要。 相似文献

An experience of with the treatment of 21 patients with tumors and local radiation injuries is described. Terms of the preceding treatment were up to 22 years. Transplantation of free vascularized bone and soft tissue transplants was performed in 14 cases, pedicled ones (by the methods of microsurgery) in 8 patients. The transplantation proved to be a success in 20 patients. Plastic operations in the complex of medical measures facilitated rapid and successful rehabilitation of patients with recurrent tumors and metastases. 相似文献
