J. appl. oral sci; 24 (3), 2016
ABSTRACT Diabetes mellitus (DM) is a disease associated with delayed wound healing of oral ulcers by increased expression of proinflammatory cytokines and cellular apoptosis. Objective to evaluate the influence of Tumor Necrosis Factor alpha (TNF-α) and apoptosis in rats with DM treated with chamo...

Use of silicon for skin and hair care: an approach of chemical forms available and efficacy

An. bras. dermatol; 91 (3), 2016
Abstract Silicon is the second most abundant element on Earth, and the third most abundant trace element in human body. It is present in water, plant and animal sources. On the skin, it is suggested that silicon is important for optimal collagen synthesis and activation of hydroxylating enzymes, improvin...

Treatment of abdominal wall hernia with suture, or polypropylene, or collagen prosthesis

Acta cir. bras; 31 (6), 2016
ABSTRACT PURPOSE: To develop an experimental model for incisional hernias and to compare morphological and functional aspects of hernia repairs by suture, polypropylene mesh and collagen mesh. METHODS: A defect measuring 7cm x 2cm was created in the anterior abdominal of 28 New Zealand male rabbits, di...

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...

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

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE : To evaluate the effects of platelet rich plasma (PRP) on the healing of fascia wherein peritonitis has been created. METHODS: Twenty eight Wistar Albino rats were divided into four groups. Only a primary fascial repair following laparotomy was performed on Group 1, a primary fascial...
