Influência da calcitonina na regeneração óssea em mandíbulas de ratas ovariectomizadas

In This work we studied the action of calcitonin on bone regeneration in the jaws of normal and ovariectomized rats with and without administration of calcitonin. One hundred rats aged approximately sixty days were used for this study. Of these fifty were ovariectomizedOv forming group and one month after the surgery, animals in all a hundred surgical bone defect was made in the angle of the mandible, creating a bone lesion of approximately 4 mm, covered with a PTFE barrier. OvThe animals were divided into two equal groups: Ov (ovaricctomizados) and LMO (ovariectomized with calcitonin). The other fifty animals, only with the bone lesion were also divided into two groups: control (C) and CM (control with calcitonin). Treated groups received the first dose of the substance immediately after surgery, the dose of 2 IU / kg IM three times per week. The animals were sacrificed after three, seven, 14, 21 and 28 days, with their jaws removed and sent for histological preparation. Densitometric analyzes were performed histological and histomorphometric verifying that it was observed that the Ov animals showed decreased bone density and a much slower regenerative process, when compared with control animals. Calcitonin proved effective in both ovariectomized animals and in those with only bone injury.

A Catuama e o bilobalide na regeneração nervosa periférica de ratos submetidos à secção do nervo isquiático

The Catuama((R)) is composed of four Brazilian plants extracts (Paullinia cupana, Trichilia catigua, Ptychopetalum olacoides e Zingiber officinale). The Catuama((R)) is known as having neuroprotector, anti-inflammatory, antioxidant and antidepressant effects. Bilobalide, extracted from leaves of Ginkgo biloba, is known by its neuroprotective effect in the central and peripheral nervous systems. The present study evaluates the effect of Catuama((R)) and bilobalide on peripheral nerve regeneration in rats following a sciatic nerve section. Sciatic nerve of forty adult rats was transected with a 10-mm gap and the proximal and distal nerve stumps were fixed in a silicone tube filled with liquid collagen. The animals were divided into four groups: the control group (A), two groups treated with Catuama((R)) by gavage along 28 days after the surgery in different doses of 100 (B) and 400mg. kg(-1) (C) and the group using 200 mu M bilobalide (D) associated with the liquid collagen in the silicone tube. Evaluations were done by a walk test on the first, fifth and tenth week after the surgery. Electrophysiological stimulation and quantitative and qualitative histological analyses of the sciatic nerve and gastrocnemius muscle were also performed on the tenth week after the surgery. All groups showed good regeneration but no statistical difference was found between treatments and control groups (P > 0.05).

Avaliação dos efeitos promovidos pela sibutramina, associadas 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.
