Due the presence of sibutramine and citalopram in a number of drugs, neurotransmitter reuptake inhibitors. Sibutramine reduces the reuptake of serotonin, norepinephrine, and dopamine; citalopram is an antidepressant drug of the selective serotonin reuptake inhibitor. The thin-layer chromatography-densitometric behavior of some centrally acting serotonin reuptake inhibitors has been studied. The...

An automatic method, utilizing the AutoAnalyzer, for titration of influenza virus haemagglutination inhibitors is described. The titres obtained compare favourably with those obtained by densitometric methods. So far, the technique has not proved superior to the densitometric methods in either speed of operation or in reproducibility but various developments are suggested to effect this.

BACKGROUND Stanozolol is a synthetic derivative of dihydrotestosterone (DHT), and one of the frequently detected anabolic steroids in doping analysis. The current work describes the development and validation of the stability-indicating TLC-densitometric method for sensitive and specific estimation of stanozolol even its degradation product being there. Precoated silica gel TLC aluminium plates...

  Background: Satureja mutica (Lamiaceae) is an herbaceous plant which grows in North-West of Iran. Oleanolic acid has been previously isolated from some Lamiaceae genus and showed a broad range of biological activities. Besides Silphium spp., Panax quinquefolium root and Calendula officinalis flower as the interesting source of oleanolic acid used in the herbal industry, here we report the iso...

BACKGROUND Proximal phalanges in horses are among bones that are most prone to injuries. So far, the detailed analysis of densitometric and geometric parameters of both front legs proximal phalanges in horses has not been investigated. The aim of this study was to compare the densitometric and geometric parameters between proximal phalanges in equine both front legs with the use of peripheral q...

To guarantee the reliability of densitometric data in clinical trials on pulmonary emphysema a quality control procedure is presented, to prevent that a measured progression in lung density could be reflected by a gradual change in the maintenance of the computed tomographic scanner. For that purpose, a foam phantom has been developed, which mimicks the densities of emphysematous lung tissue, f...

OBJECTIVE To develop a TLC-densitometric method for the determination of barakol content in Senna siamea leaf and flower extracts, and to compare the barakol content in mature leaves, young leaves and young flowers of the plant which are consumed as a vegetable in curry. MATERIALS AND METHODS The extraction of pure barakol was performed by boiling the fresh young leaves of S. siamea with 0.5%...
