The effects of low level laser therapy on Staphylococcus aureus infected third-degree burns in diabetic rats

Acta cir. bras; 31 (4), 2016
PURPOSE: To characterize the effects of low-level laser (LLL) on third-degree burn wounds which were infected with Staphylococcus aureus (S. aureus) in diabetic rats. METHODS: Thirty streptozotocin-induced diabetic rats were divided into two groups: the control and the LLL groups. Third-degree burns w...

Short hairpin RNA targeting insulin-like growth factor binding protein-3 restores the bioavailability of insulin-like growth factor-1 in diabetic rats

Int. braz. j. urol; 42 (1), 2016
ABSTRACT Purpose To investigate whether intracavernosal injection of short hairpin RNA for IGFBP-3 could improve erectile function in streptozotocin-induced diabetic rats. Materials and methods After 12 weeks of IGFBP-3 short hairpin RNA injection treatment, intracavernous pressure responses to elect...

Avaliação dos efeitos vasculares e expressão de mRNA de receptores de drogas vasoconstritoras em leito arterial mesentérico de ratos normotensos, diabéticos, hipertensos renais um-rim, um clip (1R-1C) e 1R-1C diabéticos

O presente trabalho teve como objetivo avaliar e comparar a reatividade vascular de agentes vasoconstritores presentes nas soluções anestésicas locais (Adrenalina - vasoconstrição e vasodilatação; Felipressina - vasoconstrição), nas doses de 80, 160, 320, 640 e 1280ng (adrenalina) ou 0,25; 0,5; ...

Avaliação das citocinas TNF-α, RANKL e OPG e do número de osteoclastos no reparo de defeito ósseo em calvária de ratos diabéticos tratados com matriz óssea desmineralizada

Neste trabalho, foi avaliado a participação dos osteoclastos bem como a ação das citocinas RANKL, OPG e TNF-α durante a formação e remodelação óssea em defeitos ósseos de tamanho crítico em ratos normoglicêmicos e diabéticos tratados ou não com a MAOD. Para isso, foram utilizados 250 ratos...

Diabetes mellitus affects the biomechanical function of the callus and the expression of TGF-beta1 and BMP2 in an early stage of fracture healing

Braz. j. med. biol. res; 49 (1), 2016
Transforming growth factor beta 1 (TGF-β1) and bone morphogenetic protein-2 (BMP-2) are important regulators of bone repair and regeneration. In this study, we examined whether TGF-β1 and BMP-2 expressions were delayed during bone healing in type 1 diabetes mellitus. Tibial fractures were creat...

Influence of diabetes mellitus on the mineralization ability of two endodontic materials

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the influence of diabetes mellituson tissue response and mineralization ability of Sealapex®and MTA Fillapex® sealers. Twenty-four Wistar rats were divided into two groups: diabetic and non-diabetic. The materials were placed in polyethylene tubes and impl...

Preliminary investigation about the effects of streptozotocin-induced chronic diabetes on the nerve cell number and size of myenteric ganglia in rat colon

Rev. chil. anat; 14 (2), 1996
Estudiamos el efecto de la diabetes mellitus crónica, inducida por estreptozotocina, en cuanto a los aspectos cuantitativos de las neuronas del plexo mientérico del colon proximal de ratas. Utilizamos cuatro grupos de animales: dos grupos de animales diabéticos (D2 y D8). En dos grupos D2 y D8, sacrif...
