Perfil lipídico sérico de ratos tratados com surfactante

Atherosclerosis is a multifactorial, progressive and slow disease, and hyperlipidaemia is one of the potential factors in the development of atherosclerotic cardiac diseases. The experimental dyslipidaemia carrying out advantages are the production of atheromatous lesions in a short period of time, an adequate dietetic control and environmental factors, the possibility of studies concerning reversibility of atherosclerotic lesions, and pre-clinic experiments with hypolipidaemic substances. This study aims at evaluating tyloxapol analyzing serum lipid levels. Twenty-eight healthy Wistar adults' albino male rats, weighing an average of 200 g were utilized. They were distributed into four experimental groups with seven animals each, as follows: Group I - (control); Group II - treated with tyloxapol at a dose of 500mg/kg of body weight, through intraperitoneal via each 48 hours, for two weeks; Group III - treated with tyloxapol at a dose of 500mg/ kg of body weight, through intraperitoneal via each 48 hours, for three weeks; Group IV - treated with tyloxapol at a dose of 500mg/kg of body weight, through intraperitoneal via each 48 hours, for four weeks. As lipid profile evaluation is concerned, the values of triacylglycerols and HDL have indicated that group III has significantly differed from group I and the values of total cholesterol and LDL have indicated that group I has significantly differed from group II, III and IV. It was concluded that for the studied period the surfactant tyloxapol was effective to inducing hyperlipidaemia.

Fluazuron-induced morphophysiological changes in the cuticle formation and midgut of Rhipicephalus sanguineus Latreille, 1806 (Acari: Ixodidae) nymphs

The present study demonstrated the effects of the arthropod growth regulator, fluazuron (Acatak®), in the formation of the integument and digestive processes of Rhipicephalus sanguineus nymphs fed on rabbits treated with different doses of this chemical acaricide. For this, three different doses of fluazuron (20, 40, or 80 mg/kg) were applied pour on to the hosts (groups II, III, and IV), as well as distilled water to the control group. On the first day after treatment (24 h), the hosts were artificially infested with R. sanguineus nymphs. After full engorgement (7 days), the nymphs were removed, placed on labeled Petri dishes, and kept in biochemical oxygen demand incubator for 7 days. The engorged nymphs were then taken for morphological, histochemical, and histological analyses. The results showed the occurrence of cytological, morphohistological, and histochemical alterations in the integument and midgut of nymphs from all the different treated groups. These alterations occurred at cuticular level in the subdivisions of the cuticle, related to the size of the digestive cells, amount of accumulated blood elements, and digestive residues, as well as the presence of vacuoles in the cytoplasm of the digestive cells. Thus, this study demonstrated that fluazuron acts on the integument and midgut cells of R. sanguineus nymphs fed on treated rabbits and pointed out the possibility of the use of this chemical - which is more specific, less toxic, and less harmful to the environment and nontarget organisms - in the control of R. sanguineus, at least in the nymphal stage of its biological cycle. © 2012 Springer-Verlag.
