a study was made on the interaction between histon h1 and sodium n-dodecyl sulphate (sds) in the presence of sodium arsenate inside a phosphate buffer of ph 6.4, using spectroscopy and equilibrium dialysis at 27 °c. the binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the wyman binding potential. the binding data hs been analysed in terms of hi...

the methanolic leaf extract of thuja occidentalis was evaluated for possible sedative activities in mice. sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (epm) tests at 200mg/kg and 400 mg/kg.  the extract decreased the locomotor activity of mice in hole cross, open field and epm test and showed the remarkable resul...

to determine the complications of gold sodium thiomalate therapy in rheumatoid arthritis (ra), 32 patients with active ra (27 female, 5 male) treated for a mean period of 28 ? 14 weeks were studied. from these patients, 62.5 (46-79) percent showed at least one drug reaction. pruritus was the most common complication occurred in 59 (42-76) percents, and was accompanied by skin rush in 37 (15-57)...
