Avaliação dos efeitos promovidos pela sibutramina, associada ou não à nicotina, nos tecidos reprodutivos de ratas albinas

Sibutramine is a drug recommended clinically for the treatment of obesity, but there are women that use the drug for maintenance of body weight. Many time this use occur associate to habit of tabagism, being the nicotine the main toxic compound in the cigarette. The goal of study was to evaluate the side effects promoted by sibutramine, associated or not to nicotine, in the reproductive tissue of adult female rats. Wistar animals (n =30), were distributed in the groups: a) Control A (0.3 mL of distilled water; oral); b) Sibutramine (15 mg/kg of body weight; oral); c) Control B (0.3 mL of saline solution; intraperitoneal); d) Nicotine (4.0 mg/kg of body weight; intraperitoneal); e) sibutramine + nicotine. The treatments were conducted during 30 consecutive days (single dose, daily). Sibutramine, associated or not to nicotine, affected the folliculogenesis and luteogenesis. There were significant alterations (p<0.05) in the thickness of uterine layers, considerate each treatment. In conclusion, the administration isolated of sibutramine or nicotine promoted deleterious effects in the reproductive tissues of female rats and these effects were potential in the group that received both drugs.

Investigation on the s of guava (Psidium guajava L.) infusions on germination, root tips and meristematic cells of Latuca sativa

Guava (Psidium guajava L.) is a plant often employed in popular medicine. Recently several studies have alerted about the toxicity of substances present in medicinal plants, which can pose risks to the human health. In this sense, the present work aimed to investigate the phytotoxic, cytotoxic and genotoxic action of three guava varieties - Paluma, Pedro Sato and Roxa (purple) - on the plant test system Lactuca sativa L. Thus, macro- and microscopic evaluations were carried out for five infusion concentrations (2.5, 5.0, 10.0, 20.0 and 40.0 g.L-1) prepared from each variety. Distilled water was used as negative control. Chromatographic and spectroscopic analysis by HPLC-PAD indicated that the chemical composition of the infusion of Roxa is different than that of the infusions of the varieties Paluma and Pedro Sato. It was observed that seed germination and root growth in L. sativa exposed to infusions decreased with increasing infusion concentration, regardless of the tested cultivar. For the mitotic index, no statistical differences were observed. On the other hand, a significant increase in the frequency of cell cycle alterations was verified, especially for the highest concentrations tested. The cytogenotoxic was significant. Therefore, guava should not be used indiscriminately in popular medicine.
