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 اولDetermination of magnesium by the Titan yellow and ammonium phosphate methods.
The ammonium phosphate and Titan yellow methods for determining magnesium have been investigated, and improvements to both techniques are presented. The Titan yellow method is shown to be subject to interference which makes it unsuitable for the analysis of blood cells, food, and faecal materials, and may also affect its reliability with pathological samples of serum and urine. The relative ins...
متن کاملPromotion of the Cupellation Method for Accurate Determination of Gold Alloy’s Karat Containing Platinum-Group Metals
The main standard method for gold karat determination is the cupellation method. However, this method is not sufficiently accurate to determine gold karat in the presence of insoluble Platinum–Group Metals (PGMs), such as Ir, Ru, and Rh. In this study, for the first time, a complementary method that can be used coupled with the reference cupellation method is presented for the high...
متن کاملThe determination of serum magnesium by the molybdivanadate method for phosphate.
During the past decade there has been an increasing interest shown in the study of electrolyte balance. Magnesium, however, has played a minor r81e in these studies. There are perhaps two reasons for this; first, that serum magnesium levels remain fairly constant and, second, that magnesium determinations require special technique and equipment and are time-consuming procedures as well. There h...
