background: lead, an example of heavy metals, has, for decades, being known for its adverse effects on various body organs and systems such that their functions are compromised. objective: in the present study, the ability of lycopersicum esculentum on decrease toxic effects of lead acetate on plasma superoxide dismutase, catalase and malondialdehyde in rat. lead to adversely affect the liver t...

hard gelatin capsule filled with acetaminophen, osmotic agent (sorbitol), a release promoter (sodium dodecyl sulfate), coated with a semipermeable cellulose acetate membrane containing a hydrophobic plasticizer (castor oil) and sealed with white bees wax plug was designed. when placed in the sink water penetrates the membrane, dissolves the osmotic agent and increases the osmotic pressure insid...

the essential oil of prangos ferulacea (apiaceae) fruits was obtained by hydrodistillation and analyzed by gas chromatography (gc) and gc-mass spectrometery (ms). among the 39 identified constituents accounting for 99.99% of the total oil, the major components were chrysanthenyl acetate (26.53%), limonene (19.59%), alpha pinene (19.50%), delta-3-carene (6.56%), mesitaldehyde (6.09), and germacr...

Expression of foreign proteins in E. coli is normally inhibited by exogenous production of acetate. To overcomethis problem, various strategies have been proposed and tested to reduce the extent of acetate accumulation.Although these strategies can improve the outcome, the implementation of their proposed techniquesis not practical. Because to achieve optimal results, it requi...

Objective(s): In this study, we investigated the protective effects of piperine on lead acetate-induced renal damage in rat kidney tissue. Materials and Methods: Forty male rats were divided into 5 groups: negative control (rats were given aquadest daily), positive control (rats were given lead acetate 30 mg/kg BW orally once a day for 60 days), and the treatment group (rats were given piperine...
