Influence of low-level laser irradiation on osteocalcin protein and gene expression in bone tissue1

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate osteocalcin gene and protein expression in vitro and in an in vivo model of ostectomy. Methods: Twenty Wistar rats were assigned into two groups A (n=10, laser) and B (n=10, control). Ostectomy was performed in the femur diaphysis; the twenty fragments removed, composed in...

Role of moxifloxacin-dexamethasone in cardiac histomorphometric findings among Wistar rats from infected mothers

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To investigate cardiac changes in young rats, whose mothers underwent autogenic fecal peritonitis, during organogenesis phase and to evaluate the role of intravenous administration of moxifloxacin and dexamethasone in preventing infection-related cardiac changes. Methods: A prospecti...

Rivastigmine prevents injury induced by ischemia and reperfusion in rat liver

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate whether pre-treatment with rivastigmine is able to attenuate the I/R induced lesions in rat liver. Methods: SHAM animals or those submitted to I/R, non-treated or pre-treated with rivastigminine (2mg/kg) either 50 or 15 minutes before ischemia, were used. After I/R proto...

Tissue microarray technology and collagen evaluation to analyze surgical trauma performed with usual blade or ultrasonic harmonic scalpels in rats

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To compare wound healing performed with cold blade (CSB) and ultrasonic harmonic scalpel (UHS) in the abdominal aponeurosis of rats. Methods: Eighty Wistar rats divided into two groups and underwent midline incision in the linea alba with cold blade and harmonic ultrasonic scalpel. ...

A technical note on low cost rat laparoscopy an initial experience

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate a novel and adapted low-cost set model for laparoscopic surgery in rats. Methods: Nine Wistar rats underwent two different laparoscopic procedures, splenectomy (n=3) and distal pancreatectomy with splenectomy (n = 6), after assembling a low-cost set replacing the conventio...

Wound healing of diabetic rats treated with Moringa oleifera extract

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate if Moringa oleifera leaf aqueous extract (ME) influences the healing of skin wounds of diabetic rats. Methods: Wistar rats were used (6 rats/group). Group 1 received normal saline (NS) v.o. Group 2 received moringa extract (100mg/kg v.o) for 3 weeks. Groups 3 and 4: Stre...

Hyperbaric oxygenation on adhesions prevention after laparotomy in rats

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate the effects of hyperbaric oxygenation on prevention of adhesions in the abdominal cavity after laparotomy. Methods: Fifty four rats underwent laparotomy; stitches were made in the four quadrant parietal peritoneum and abdominal cavity closure. Animals were divided into th...

Potencial of different hydroxyapatites as biomaterials in the bone remodeling

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To analyze the therapeutic potentials of different hydroxyapatites used for the correction of bone defects in rats. Methods: Forty rats, male, albino wistar, were distributed in 4 groups. They were submitted to a 3.5 mm defect in tibia. They received low purity hydroxyapatite, Stron...

Oxidative stress effects in the uterus, placenta and fetus of pregnant rats submitted to acute and chronic stress

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate the effects of oxidative stress in pregnant rats submitted to acute and chronic stress, relating to alterations in the uterus, placenta and fetus. Methods: Twenty-four female Wistar albino (Rattus norvegicus), were divided into four groups, for induction of oxidative str...
