Distal movement of upper permanent molars using midpalatal mini-implant.

Objective: To assess whether palatal mini-implants are effective as direct anchorage for distal movement of the upper molars.

Methods: It was used an acrylic model of the upper dental arch. After making a groove in the region corresponding to dental alveolus, acrylic teeth were fixed in this groove with #7 wax, with the roots being previously immersed in adhesive wax.

Perioperative administration of probiotics: effects on immune response, anastomotic resistance and colonic mucosal trophism.

Purpose: To investigate the effects of perioperative administration of diet containing probiotics on the immune response, anastomotic resistance, and colonic mucosal trophism in rats underwent left-sided colonic anastomosis.

Methods: Sixty adults Wistar rats were randomized to two groups (A and B) with 30 animals each to receive or not a diet supplemented with probiotics (Streptococcus thermophilus e Lactobacillus helveticus) during pre- and postoperative period. They underwent laparotomy followed by left colon section and immediate anastomosis.
