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...

Quantification of individual phosphorus forms in surface sediments of the Southern Caspian Sea - Iranian Coast: A sequential extraction procedure

Seventy Two sediments from four stations (Anzali, Tonekabon, Noshahr and Amirabad), located in Caspian Sea-Iranian coast were examined on the basis of P-fractionation in autumn and winter of 2013-2014. Several forms of the phosphorus in sediment were separated and extracted according to sequential extraction method. Then the extracted phosphorus in each fraction was determined by UV–Vis spectro...

Migration and Transformation of Phosphorus Forms in Field Ditch Sediments

A broad attention has been paid to the field ditches as the sewage interception channel for the agricultural nonpoint source pollution, however, rare studies have involved in the phosphorus migration and transformation between the ditch sediments and overlaying water, especially, from the ditch sediments to the water. The present paper aims to explore with XPS binding energy data how pH, dissol...

Phosphorus Retention in Sediments

Phosphate is usually the most important growth limiting nutrient in aquatic environments-The availability of P is the result of external load and retention in the sediments. This latter is the result of a number of transport, microbial and chemical processes. 'The role of P in the productivity in systems and in the eutrophication process has initiated a large number of studies to the behaviour ...
