Purpose: To evaluate the effects of isoxsuprine and nicotine on TRAM.
Methods: Forty eight 48 Wistar rats distributed into four Groups (n=12). All rats received medication managed daily for 20 days: saline solution (SA), nicotine solution (NI), isoxsuprine solution (IS) and nicotine solution (NI) + isoxsuprine solution (IS).
Purpose: To investigate the microscopic changes in the rectus abdominis muscle in rats subjected to five delay procedure.
Methods: 30 male Holtzmann rats, weighting between 250 and 350 grams, were used. The animals were divided into five groups (n=6): A - cranial section of the right muscle; B - caudal section of the right muscle; C - craniocaudal section of the right muscle; D - cranial section reflecting the right muscle in the craniocaudal direction; E - caudal section reflecting the right muscle in the caudocranial direction.
Background: Although the occurrence of spleen alterations in the various forms of dyslipidemia, such as Gaucher's disease, has been well established, the relation between the spleen and lipid metabolism has not been properly studied. In order to contribute to the filling of this gap, in the present investigation we assessed experimentally the lipidogram of rats in the presence of the spleen, in asplenia, and after conservative spleen surgeries.
Methods: Forty female Wistar rats of similar weight and age were divided into 4 groups submitted to the following procedures: Group 1--control, with an intact spleen; Group 2--total splenectomy; Group 3--subtotal splenectomy, and Group 4--total splenectomy complemented with autogenous spleen tissue implants.
