[Analysis of anatomical pieces preservation with polyester resin for human anatomy study].

Objective: To evaluate the use of polyester resin in preserving anatomical specimens for the study of human anatomy.

Methods: We used 150 anatomical specimens, comprised of unfixed (fresh), fixed in 10% formalin and vascular casts of organs injected with vinyl acetate and polyester resin. The solution used consisted of polyester resin with the diluent styrene monomer and catalyst (peroxol).

Oxidative stress parameters in women with breast cancer undergoing neoadjuvant chemotherapy and treated with nutraceutical doses of oral glutamine.

Purpose: To evaluate the effects of oral administration of GLN on the oxidative stress in women with breast cancer undergoing neoadjuvant FAC chemotherapy (5 fluouracil 500 mg/m²+Doxorubicin 50 mg/m²+Cyclophosphamide 500 mg/m² body surface area).

Methods: Twenty women (mean age: 51.7 years) with breast ductal carcinomas classified as T3 or T4 were included in the study, regardless of pre or post menopause status.

Preconditioning with L-alanyl-L-glutamine in a Mongolian gerbil model of acute cerebral ischemia/reperfusion injury.

Purpose: To investigate the effect of L-alanyl-L-glutamine (L-Ala-Gln) preconditioning in an acute cerebral ischemia/reperfusion (I/R) model in gerbils.

Methods: Thirty-six Mongolian gerbils (Meriones unguiculatus), (60-100g), were randomized in 2 groups (n=18) and preconditioned with saline 2.0 ml (Group-S) or 0.

Morfometric study of arterial branching of the spleen compared to radiological study.

Objective: To study the distribution of the branches of the splenic artery and relate it to the radiological study of its intraparenchymal distribution, aiming to use this knowledge in partial splenectomy.

Methods: In the macroscopic study, we used 60 human spleens which the splenic artery dissected from its origin to observe the division and the terminal branches directed to the spleen. We measured the distance between the visceral surface of the spleen and the terminal division of the splenic artery and the emergence of the polar branches.

L-alanyl-glutamine preoperative infusion in patients with critical limb ischemia subjected to distal revascularization reduces tissue damage and protects from oxidative stress.

Background: Critical limb ischemia (CLI) is the most severe form of peripheral vascular disease where there is inadequate blood flow to a limb. Our aim was to examine the effects of preoperative infusion of l-alanyl-glutamine (l-Ala-Gln) during the ischemic period and during the first 30 minutes following blood reflow in patients with CLI who are undergoing distal femoral artery bypass surgery.

Methods: Thirty-two patients with CLI were alternately allocated to group 1 (saline) or group 2 (l-Ala-Gln).

[Laparoscopic cholecystectomy training on plastic mannequins].

Objective: The objective of this project is to offer for any Medical Education Institution an effective method of learning and developing the skills on this new surgery procedure that is necessary to improve the ability as consequence of technological innovations.

Methods: Simple and low cost materials were used for doing and carrying on the laparoscopic cholecystectomy on plastic mannequins as if it were done in vivo.

Results: The results were shown through illustrated photographs from the surgery procedures.
