Hepatotoxic evaluation in albino rats exposed to ceftriaxone
ISBN: 9783848496402 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The hepatotoxic effect and biochemical alterations induced by ceftriaxone were investigated in rats following repeated intramuscular injections of 180 and 360 mg/kg b.wt. daily for five consecutive days. Ceftriaxone produced significant increase in serum concentrations of liver enzymes (AST and ALT), total bilirubin, cholesterol, Tg and LDL-cholesterol. Ceftriaxone also caused significant decrease in albumin and HDL-cholesterol. Ceftriaxone injection in the tested doses caused histopathological changes in liver. The severity of these changes was dose dependant. In conclusion, the hepatic...

Cationic Surfactants as Corrosion Inhibitors under H2S environment
ISBN: 9783659665547 / Angielski / Miękka / 2014 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil extraction and processing industries, inhibitors have always been considered to be the first line of defense against corrosion. A great number of scientific studies have been devoted to the subject of corrosion inhibitors.Cationic surfactants represent only 5-6% of the total surfactant production. However they are extremely useful for some specific uses, because of their peculiar properties .They are not good detergents nor foaming agents, and they cannot be mixed in formulations which...
