Repetitive counterelectrophoresis (RCE), which has been described (Hayano and Tanaka, 1977), was used to assay the contents of antibodies to streptococcal esterases (STE) in sera from patients with scarlet fever. The levels of antibodies to STE were expressed semiquantitatively by reading the intensity of the colored spot developed by RCE with a densitometer. The present study deals with the de...

A method of electrophoresis utilizing cellulose acetate is described wherein quantitation of serum protein fractions by densitometry is accomplished within 2 hr. of initiation of the procedure. The densitometer was found to have a linear response to amido black dye. Albumin and y-globulin demonstrated equal dye-binding characteristics. Combined with the absence of albumin trailing, this has aff...

ABIOUS TECHNICS HAVE BEEN EMPLOYED in observing the end points in performing prothrombin determinations. Some of these entail the use of wire loops (1), direct visual observation of the clot (2), and use of densitometers (3). In our laboratories we have adopted the method of Quick (2). We have found that with the aid of an improvised viewer, observations of any physical clot can be studied and ...

The operation of a gamma densitometer (GD) ID = 100 mm is considered; it intended for the diagnostics three-phase oil–water–gas flows using separationless method, when composition components determined by spectrometric analysis irradiation with two different photon energies. 241Am and 137Cs isotopes, installed in same housing, are used as sources, while detector made on basis BGO crystal 40 dia...

OBJECTIVE TBesides aging there are multiple factors involved in decreasing Bone Mineral Density. Knowing the burden of the diseaseand its related factors in our population can help better treat this. Therefore, our objective was to identify subjects with low Bone Mineral Density (BMD) and its risk factors in hospital visiting people in Islamabad. METHODS Descriptive cross sectional study was ...

Aim: This descriptive-relational study aims to identify osteoporosıs health belief, knowledge level and risk factors in individuals whose bone mineral density was required. Method: Target population of the study was 110 men and 126 women aged 35 and over, who applied to Atatürk University Aziziye Yakutiye Research Hospital Nuclear Medicine Center Bone Densitometer Unit between January 2010 and ...

The visible absorption spectra of Kodak X-Omat V film, which had been exposed to various doses of radiation, have been investigated to analyse the dosimetry characteristics of the film with various densitometers. Common densitometers can use fluorescent light (broad band visible), helium-neon (632 nm) or other spectra of specific bandwidth. The visible absorption spectra show a slight peak in a...
