structural coupling between alpha and beta cells (4), we wonder whether the paradoxical behavior here disclosed may not be somehow related to a functional uncoupling of these cells as the result of calcium deprivation (15). If so, the present protocol might prove useful for further studies on the significance of intercellular bridging in the physiology and pathology of islet tissue. VIVIANE LEC...

Letter to editor "An Outlook on the Role of Genetic and Environmental Factors in Asthma"

سردبیر محترم مقاله ارزشمند چاپ شده توسط علیدادی و همکاران با عنوان"چشم اندازی به نقش عوامل ژنتیکی و محیطی در بیماری آسم" دوره 27 شماره 151 مرداد 96 مورد مطالعه قرار گرفت. نویسندگان در این مقاله مروری اشاره خوبی به نقش ژنتیک و به میزان کمتری به عوامل محیطی داشته‌اند(1). همان‌طور که بیان داشته‌اند ژن های متعددی در بروز آسم نقش دارند و سبب فنوتیپ های مختلف آسم می شوند. اما در این میان نقش عوامل...

Prostaglandins

Knowledge of the structure and synthesis of antibodies (immunoglobulins) has developed to a remarkable degree in the last decade. Distinct classes of immunoglobulin (yG, yM, -yA, yD, yE, and their subgroups) have been identified and shown to consist of fixed numbers of light and heavy polypeptide chains organized in pairs. Each polypeptide has a segment of variable amino acid sequence; the spec...

Prostaglandins and glaucoma.

Human aqueous humour was found to contain a substance which contracted the rat stomach strip. The mean activity was significantly higher in specimens from open angle glaucoma cases than in specimens from patients with cataract. The pharmacological and chromatographic properties of the active material were studied in aqueous humour obtained from cadavers; activity seemed to be due to prostagland...
