A simple method for the determination of serum cholesterol

A simple method for the determination of serum haptoglobins.

Changes in the serum haptoglobin level have been reported in certain forms of anaemia (Allison and ap Rees, 1957; Allison, 1958; Nosslin and Nyman, 1958; Nyman, Gydell, and Nosslin, 1959), in hepatobiliary disease (Owen, Mackay, and Got, 1959) and in various inflammatory and chronic diseases (Jayle and Boussier, 1955; Allison and Blumberg, 1958). A simple colorimetric procedure for the determin...

Development of a Simple and Sensitive Terbium Sensitized Fluorescence Method for Determination of Epinephrine and Norepinephrine in Serum

     A simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (NE) and epinephrine (EP), in serum samples was developed. The method is based on the fluorescence sensitization of terbium (Tb3+) by complexation with both catecholamines in the presence of lanthanum (La3+), as a co-cation, and in a Na...

A simple spectrophotometric method for the determination of blood sugar by phenylhydrazine Hydrochlorlde

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

A simple method for the determination of the cholesterol esterase activity.

The proposed method determines the activity of cholesterol esterase (CEH) and takes advantage of its ability to catalyze the hydrolysis of cholesterol esters naturally present in human serum. The assay is based on Allain's method of spectrophotometric determination of cholesterol by means of cholesterol oxidase, peroxidase, but using 3,5-dichloro-dihydroxybenzenesulfonic acid (DHBS) as phenolic...

Gas-chromatographic determination of cholesterol in serum: candidate reference method.

We present a candidate Reference Method for determination of total cholesterol in serum. The method is based on high-resolution capillary gas chromatography, and we took special precautions with respect to weighing, calibration, and chromatographic peak integration. Analytical recovery of added cholesterol was essentially complete (99.99%, SD 0.48%) and reproducibility was excellent (total CV 0...
