In order to test photoelectric recording of dye curves, simultaneous determinations of cardiac output were made in 48 patients with heart disease with the Fick and dye-dilution technics. The dye curves were recorded with a Colson densitometer following either intrathoracic or antecubital injection of dye. Both Evans blue and indoeyanine green dyes were employed. Satisfactory agreement was noted...

This study describes the response of cattle to a dot enzyme-linked immunosorbent assay (ELISA) using sera absorbed with Mycobacterium phlei. Results obtained by visual observation are compared with those obtained using a densitometer. Infection status of cattle was determined by faecal culture. Cattle of different levels of exposure and disease manifestation were examined. A significantly highe...

Methods: We carried out measurements of bone mineral density (BMD) of lumbar spine and femoral neck using DXA, QUS of heel using ultrasound densitometer, and BMD of forearm using SXA. We performed all the measurements at the Nuclear Medicine Division of King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between 2002 and 2004. We obtained the measurements of 437 female adult patien...

A computer program has been written for off-line calculation of relative and absolute percentages of the five serum protein fractions usually seen on cellulose acetate electrophoretograms, with use of manually observed peak heights on densitometer scans. With myeloma-like peaks, both peak height and width at half-peak height must be measured. Routine application of the program saves technician ...

2014 A sealed volumeter for the study of liquid mixtures near their solution critical point is described The cell used allows optical investigations to be performed at the same time. Although the method is very simple, high accuracy can be obtained (d03C1/03C1 = 3 x 10-6 relative and 4 10-5 absolute) in a wide temperature range. Revue Phys. Appl. 19 (1984) 917-919 OCTOBRE 1984, PAGE Classificat...

OBJECTIVE The purpose of this study was to investigate the association between an AluI RFLP of the calcitonin receptor (CTR) gene and quantitative ultrasound (QUS) parameters in Korean men, and the interaction with nutrition as a lifestyle factor. MATERIALS AND METHODS Broadband ultrasound attenuation, speed of sound and stiffness index of the calcaneus were measured using an ultrasound bone ...

In this recent study, several trials were made to develop a HPTLC method for quantification of scopoletin and piperine in the Ajmodadi formulation. was done on pre-coated silica gel 60 F254 plates with mobile phase toluene:ethyl acetate:methanol:formic acid (3.9:3.9:0.3:1.7 v/v/v/v). The retardation factors 0.75 0.86 found good defined resolution peak. Densitometer analysis carried out at 335 w...
