Why do patients undergoing anterior cruciate ligament reconstruction in Brazil stay in hospital for longer periods than in other countries? Prospective evaluation of 30 patients and presentation of possible discharge criteria.

Objective: Evaluate a better moment by the medical team and patient to be discharged and relate to possible medical discharge criteria.

Methods: 31 anterior cruciate ligament reconstructed patients under similar conditions prospectively evaluated about the possibility of discharge with 24 and 48 hours after surgery and possibles discharges criteria such as pain, range of motion and capacity quadriceps contraction, besides the use of a validated scale to measure the patient's functional independence.

Results: 50% and 6.

Liver and lung late alterations following hepatic reperfusion associated to ischemic preconditioning or N-acetylcysteine.

This study aimed the effect of n-acetylcysteine or ischemic preconditioning in hepatic and pulmonary damage after liver ischemia-reperfusion injury. Twenty-four male Wistar-EPM rats were assigned into four groups: (IR) Hepatic ischemia-reperfusion; (IPC) IPC achieved before hepatic ischemia; (NAC) Animals received NAC pretreatment; and Sham operated group. After 24 h of hepatic reperfusion, blood, liver, and pulmonary samples were evaluated.

Late transplantation period of mice fetal intestine grafts: morphometric aspects.

Morphometric evaluation of the fetal intestinal graft in the late post-transplant period was done by using C57BL/6 mice. Under anesthesia, after hysterotomy, a transversal laparotomy was done in the fetus to harvest all intestines. Grafts, cleaned from its mesentery, and divided were transplanted into the preperitoneum space, from male mice, C57BL/6 strain.
