Background & Aim:  The hot water extract of a mixture of Anogeissus leiocarpus and Prosopis africana is widely used in the northern part of Nigeria for the treatment and management of asthma. Since investigations of its pharmacological activities already justify its use, and the need for standardization of herbal medicine and develop appropriate dosage forms has continued to g...

Stability of ceftiofur sodium and cefquinome sulphate in intravenous solutions was studied. Chromatographic separation and quantitative determination were performed by using a high-performance liquid chromatography with UV-DAD detection. During the stability study, poly(vinylchloride) minibags were filled with a solution containing 5 mg of ceftiofur sodium or cefquinome sulphate and diluted to ...

An occlusive patch-test assay has been developed for assessment of topical retinoid action in human epidermis. Previous work with this assay has demonstrated marked epidermal hyperplasia in skin treated with topical all-trans-retinoic acid for 4 days and similar effects with the local irritant, sodium lauryl sulphate. To investigate the capabilities of this assay further, a time-course and dose...

Zinc (Zn) and selenium (Se) exert regulatory activities on immune functions, while cadmium (Cd) is an immunotoxic agent. The object of this study was to detect effects of 10-4, 10-5, and 10-6 M Cd sulphate, Zn sulphate, and sodium selenite, and their combinations on human peripheral blood mononuclear cell (PBMC) proliferation and IFN-γ and TNF-α production. Only 10-5 M Zn sulphate significantly...

The following factors were measured for extracellular haemoglobins of Artemia salina: a minimal molecular weight of globin chain per haem group (based on the iron and haem contents), the absorption coefficients, the absorption spectra of various derivatives and the amino acid compositions. These were compared with those of the haemoglobins of other invertebrates. Three Artemia haemoglobins (I, ...

The objective of this work was design, characterization, and optimization of controlled drug delivery system containing antibiotic drug/s. Osmotic drug delivery system was chosen as controlled drug delivery system. The porous osmotic pump tablets were designed using Plackett-Burman and Box-Behnken factorial design to find out the best formulation. For screening of three categories of polymers, ...

The SLC51 organic solute transporter family of transporters is a pair heterodimeric proteins which regulate bile salt movements in the small intestine, duct, and liver, as part enterohepatic circulation [2, 5, 1]. OSTα/OSTβ also expressed steroidogenic cells brain adrenal gland, where it may contribute to steroid sulphate movement [6]. Bile acid transport suggested be facilitative independent s...

An investigation was conducted on the anodisation of commercial grade aluminium in aqueous sodium sulphate and sodium oxalate solutions. The parameters investigated were anodisation potential and electrolyte composition. Degree of anodisation was evaluated by visual observation of the anodised surface, analyses of current-concentration graphs at constant potential and current-potential characte...
