ABBOUD, Renato de Souza et al. The action of avocado oil on the lipidogram of wistar rats submitted to prolonged androgenic stimulum. Nutr. Hosp. [online]. 2015, vol.32, n.2, pp.96-701. ISSN 1699-5198.

Introduction: the abuse of steroid hormones administered in chronic form may cause alterations in the lypidic profile, conveying na increase in the levels of LDL, and reduction in the levels of HDL. In average, 53.44% of the lypidic composition of the avocado core is composed of oleic acid (which is a phytosterol) and the study of the hypolipemiating effect of these substances has been performed aiming at the prevention and control of dislypidemias. Objective: to assess the potential hypolipemiant power of the avocado oil on the lypidogram of adult male Wistar rats submitted to prolonged androgenic hiperestimulation. Materials and methods: twenty eight Wistar rats were divided in 4 groups of 7 animals: the control group (CG); Avocado Oil Group (AOG) fed with a staple based on Avocado Oil; Induced Grupo (IG); and the Induced Grupo fed with a staple based on Avocado Oil (AOIG). The inducing was performed through surgery to subcutaneously implant sillicon pellets suffed with 1ml of testosterone propionate which were replaced at every 4 weeks. Results: VLDL (AOIG: 28.14 ± 4.45; IG:36.83 ± 5.56 mg/ml); Triglicerides (AOIG: 140.07 ± 22.66; IG: 187.2 ± 27 mg/ml); HDL (AOIG: 40, 67 ± 1.2; GI: 35.09 ± 0.8; AOG: 32.31 ± 2.61 e CG: 32.36 ± 4.93mg/ml) Testosterone (AOIG:1.42 ± 0.46; GI: 2.14 ± 0.88; AOG: 2.97 ± 1.34 e CG:1.86 ± 0.79ng/ml). Conclusion: avocado Oil exerted a direct regulating effect on the lypidic profile, acting efficiently on animals submmited to androgenic stimulation through a prolonged period.
