the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle
نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولSeed Alkaloids Content and Antioxidant Enzymes Activity in Black Henbane as Influenced by Ammonium Nitrate Application and Water Deficit Stress
Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Objective: This study intended to investigate the nitrogen (N) fertilization and water deficit stress (WDS) effects on seed tropane alkaloids elicitation including hyoscyamine (HYO) and scopolamine (SCO), and ...
متن کاملAutomated, simultaneous microdetermination of calcium and magnesium by atomic absorption.
A procedure is described for the simultaneous, automatic determination of serum calcium and magnesium with the AutoAnalyzer, and a dualchannel, double-beam atomic absorption spectrophotometer, the IL Model 153. Advantages over existing procedures include a high rate of analysis (90 samples or 180tests per hour) and low sample consumption (a total of 30 l for both determinations). We have compar...
متن کاملMeasuring the Density of Calcium and Magnesium Elements in Pistachio Leaf by ICP Modern Method and Comparing it With Titration Methods and Atomic Absorption
Introduction: Calcium critical limit in pistachio plants is about 1.3 percent of plant dried material; magnesium critical limit in pistachio leaves is about 0.6 percent of plant dried material. To measure calcium and magnesium there are several methods in which three methods of titration and atomic absorption that are more common and used to libraries more in addition to ICP modern method are u...
