Quantum dots are new types of fluorescent materials for biological labeling. As a result, QDs toxicity study is an essential requirement for future clinical applications. Therefore, the cytotoxic CdSe:ZnS quantum dots effects on some organs in mice are presented in this study. In this work, 10, 20 and 40 mg/kg doses of CdSe:ZnS quantum dots were injected to 32 adult male mice. Structural and op...

We investigated the in vivo antimalarial effect of crude extract of Tinospora crispa, a Thai traditional medicine plant. Mice were inoculated with Plasmodium yoelii then treated with the crude extract of Tinospora crispa at doses of 20, 40 and 80 mg/kg. Mice receiving the dose of 20 mg/kg died on average on Day 8. Mice remained alive longer when treated of the dose of 40 mg/kg or even longer un...

Performance and Cu status were measured in growing and finishing steers supplemented with different copper (Cu) concentrations and sources. Sixty Angus (n = 36) and Angus x Hereford (n = 24) steers were stratified by weight and initial liver Cu concentration within a breed and randomly assigned to treatments. Treatments consisted of 1) control (no supplemental Cu); 2) 20 mg Cu/kg DM from Cu sul...

The effect of MDMA (3,4-methylenedioxymethamphetamine), a psychotropic amphetamine derivative, treatment on the rate of serotonin (5-hydroxytryptamine; 5-HT) synthesis in the rat brain was studied by autoradiography using alpha-[14C]-methyl-l-tryptophan method. Three different treatment protocols were compared to the control (saline) treated rats: (1) rats treated twice with 10 mg/kg every 12 h...

The pharmacokinetics of active components such as baicalein, wogonin and oroxylin A were evaluated after oral administration of a purified extract of Scutellaria baicalensis GEORGI (PF-2405) containing the high contents of baicalein, wogonin and oroxylin A to rats. Following oral administration of PF-2405 at 10, 20 and 40 mg/kg dose (equivalent to 4.5, 9.0 and 18 mg/kg baicalein), a major const...

colocasia esculenta linn (ce) is traditionally used for the treatment of various ailments such as high blood pressure, rheumatic pain, pulmonary congestion, etc. hence in present study, the effect of aqueous extract of ce leaves (aece) was evaluated for antihypertensive and acute diuretic activity in rats. preliminary phytochemical evaluation revealed the presence of carbohydrate, saponins, tan...

The pharmacokinetics of AL-226, a new semi-synthetic cephalosporin, were studied after i.v. and i.m. administrations to rabbits at doses of 10, 20, 30 and 40 mg/kg. The average values of the pharmacokinetic parameters after bolus i.v. administration of the antibiotic expressed by an open two-compartment kinetic model were: alpha = 0.131 min.-1, beta = 0.0341 min-1, K12 = 0.0287 min.-1, K21 = 0....
