Antibacterial activity of the aerial extracts from Xanthium brasilicum prepared in methanol, diethyl ether, petroleum benzene and an equal mixture of the three solvents were studied against bacterial laboratory standards and clinical isolates using the disk diffusion method. The best antibacterial results were obtained when methanol or the solvent mixture was used. The crude extract with the hi...

Bauhunia semibifida is among the several plants that have been studied for their medicinal properties. native to India. However, some species found in Africa. It has important uses, such as anti-bacterial, anti-inflammatory and anti-cancerous. This study aimed primarily at carrying out a preliminary phytochemical screening ascertain classes of bioactive compounds present solvent system(s) separ...

The aim of this research is to develop a silica gel and alumina column chromatography for separation of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) into two groups. This is achieved by optimizing the cut-off volume of eluting solvent and weight ratio of silica gel and alumina. In this process mixture of PAHs and PCBs divide in two groups and simultaneously o...

Background: Plasminogen is one of the compounds derived from human plasma. Activation of plasminogen produces plasmin. Plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. The aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine Sepharose. Materials and Methods: Normal human plasma was used as the...

BACKGROUND We present the case of an 80-year-old woman who was admitted to hospital with an intermittent volvulus of the right colon. A total colectomy was performed. Initially, serum amylase and lipase increased concordantly, but after a few weeks amylase normalized (85 U/L), whereas lipase increased to 3764 U/L. This discrepancy and persistence of hyperlipasemia suggested a macromolecular for...

The partial purification of beef thyrotropin with the cation exchangers Amberlite IRC-50 (2, 3) and carboxymethyl (CM) cellulose (3, 4) has been previously reported. The preceding paper (5) describes the rechromatography on diethylaminoethyl (DEAE) cellulose of thyrotropin preparations assaying 20 U.S.P. units per mg which resulted in fractions apparently containing only those glycoproteins wit...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...
