Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias
Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias) and porphyrias. Porphyrias are classified as hepatic and erythropoietic porphyrias based on the organ system in which heme precursors (5-aminolevulinic acid (ALA), porphobilinogen ...
متن کاملThe effect of water borne nickel on iron metabolism and heme biosynthesis in common carp (Cyprinus carpio)
Nickel is an essential element for all living organisms such as microorganisms, plants and animals. When nickel concentration exceeds the necessary concentration, could be toxic, and likewise causes adverse effects in living organisms. In this study, following determining nickel LC50-96h for common carp (Cyprinus carpio), nickel sub-lethal treatments including 0 (control), 0.055, 0.275, 0.572, ...
متن کاملPorphyrin Metabolism
The suggestion of Duesberg (1) that prolonged ingestion of allylisopropylacetylcarbamide (Sedormid)’ may have induced acute porphyria in a human led later workers to produce this disorder in rabbits (2) and rats (3) by oral administration of the drug. Although this experimental procedure has facilitated the study of acute porphyria, the possibility remains that some of the porphyrin excreted in...
متن کاملPorphyrin concentration and myeloperoxydase activity in the tissues of the Shay chloroma of the rat.
BSERVATIONS on human chloroleukemic tissue have shown that it contains porphyrin, which accounts for its red fluorescence in Wood’s light1 and an enzyme, myeloperoxydase (or verdoperoxydase), to which the green color of the chloroleukemic tissue is due.2 In recent years many chloroleukemic tumors have been described in animals where the tumor tissue also contained porphyrin and myeloperoxydase....
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
