Pharmacological study of edema induced by venom of the snake Bothrops asper (terciopelo) in mice
(1995-01)
The effect of several drugs on the edema-forming activity of Bothrops asper venom was studied plethysmographically using the mouse foot pad assay. Bothrops asper venom induced a dose-dependent edema which developed rapidly ...
Smear layer removal capacity of disinfectant solutions used with and without EDTA for the irrigation of canals: a SEM study.
(2003-10-01)
The purpose of this study was to carry out a scanning electron microscopic (SEM) analysis of the cleaning qualities and smear layer removal from root canal walls, instrumented and irrigated with 2.5% NaOCl, 2.0% chlorhexidine ...
Effectiveness of EDTA and EDTA-T brushing on the removal of root surface smear layer.
(2003-10-01)
The purpose of this study was to compare the removal of root surface smear layer following active application of EDTA gel and EDTA-T (texapon) gel in different concentrations (5%, 10%, 15%, 20% and 24%), using scanning ...
Microwave-induced fast decalcification of rat bone for electron microscopic analysis: An ultrastructural and cytochemical study
(2007-12-01)
Bone decalcification is a time-consuming process. It takes weeks and preservation of the tissue structure depends on the quality and velocity of the demineralization process. In the present study, a decalcification methodology ...
Calcium hydroxide intracanal dressing removal with different rotary instruments and irrigating solutions: A scanning electron microscopy study
(2010-11-30)
This study evaluated the efficacy of 2 types of rotary instruments employed in association with sodium hypochlorite (NaOCl) or EDTA in removing calcium hydroxide (CH) residues from root canals dentin walls. Forty-two ...
Effects of basic fibroblast growth factor on density and morphology of fibroblasts grown on root surfaces with or without conditioning with tetracycline or EDTA.
(2007-09-01)
A study was conducted to evaluate in vitro the effect of root surface conditioning with basic fibroblast growth factor (b-FGF) on morphology and proliferation of fibroblasts. Three experimental groups were used: non-treated, ...
Inhibition of the hemorrhagic activity of Bothrops asper venom by a novel neutralizing mixture
(1997-06)
This study screened 25 sera, 19 synthetic products and five antivenoms obtained after immunization for their ability to neutralize the hemorrhagic activity of venom from the snake Bothrops asper. Among the sera screened, ...
