A histomorphometric study of unmyelinated fibers of the fibular nerve in Wistar rats

Arq. neuropsiquiatr; 74 (5), 2016
ABSTRACT There are few histomorphometric studies on the unmyelinated fibers of the fibular nerve in rats, and the number of experimental studies using this nerve has been increasing in the last years. Sixty-two percent of the endoneurial area from 10 fibular nerves of adult Wistar rats was scanned by ele...

Antibacterial properties and healing effects of Melipona scutellaris honey in MRSA-infected wounds of rats

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE : To investigate the antimicrobial, immunological and healing effects of Melipona scutellaris honey on infected wounds of rat skin. METHODS: Twenty four Wistar rats were distributed in four groups (6-each). The uninfected skin wounds of group I rats were treated daily with saline for ...

Simvastatin and biphasic calcium phosphate affects bone formation in critical-sized rat calvarial defects

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE: To investigate the effects of locally applied simvastatin plus biphasic calcium phosphate (BoneCeramic(r)) or collagen sponge on bone formation in critical-sized bone defects. METHODS: Thirty defects of 5mm in diameter were created bilaterally with a trephine bur in the calvariae of f...

Characteristics of the fibroplasia and collagen expression in the abdominal wall after implant of the polypropylene mesh and polypropylene/polyglecaprone mesh in rats

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE: To compare fibroplasia and the resistance of the abdominal wall when polypropylene meshes and polypropylene/poliglecaprone are used. METHODS: Seventy-seven male Wistar rats were divided into three groups: Control Group (for resistance); Group E (polypropylene mesh); and Group U (polyp...

Medication-related osteonecrosis of the jaw. Introduction of a new modified experimental model

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE : To evaluate a modified experimental model for medication-related osteonecrosis of the jaw (MRONJ) through the upper right central incisor extraction followed by intravenous bisphosphonate administration. METHODS: Forty five rats underwent the upper right central incisor tooth extrac...

Quantitative analysis of the renal aging in rats. Stereological study

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE: To evaluate the renal function and the renal histological alterations through the stereology and morphometrics in rats submitted to the natural process of aging. METHODS: Seventy two Wistar rats, divided in six groups. Each group was sacrificed in a different age: 3, 6, 9, 12, 18 and...

Effects of platelet rich plasma on fascial healing in rats with fecal peritonitis

METHODS: Forty two male Wistar rats were randomly divided into two groups of 21, COX and control group. To COX meloxicam in combination with morphine was given in 3 days period. Control g...

Sevoflurane preconditioning during myocardial ischemia-reperfusion reduces infarct size and preserves autonomic control of circulation in rats

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE: To investigate the myocardial ischemia-reperfusion with sevoflurane anesthetic preconditioning (APC) would present beneficial effects on autonomic and cardiac function indexes after the acute phase of a myocardial ischemia-reperfusion. METHODS: Twenty Wistar rats were allocated in thr...
