Periapical bone response to bacterial lipopolysaccharide is shifted upon cyclooxygenase blockage

J. appl. oral sci; 27 (), 2019
Abstract Objectives: Infection, inflammation and bone resorption are closely related events in apical periodontitis development. Therefore, we sought to investigate the role of cyclooxygenase (COX) in osteoclastogenesis and bone metabolism signaling in periapical bone tissue after bacterial lipopolysacc...

The role of potassium channels in the endothelial dysfunction induced by periodontitis

J. appl. oral sci; 26 (), 2018
Abstract Objective: Periodontitis is associated with endothelial dysfunction, which is clinically characterized by a reduction in endothelium-dependent relaxation. However, we have previously shown that impairment in endothelium-dependent relaxation is transient. Therefore, we evaluated which mediators ...

Acetylcholine produces contractions mediated by the cyclooxygenase pathway in arterial vessels in the Chilean frog (Calyptocephalella gayi)

Braz. j. biol; 77 (4), 2017
Abstract Previous studies performed in marine fish (I. conceptionis and G. laevifrons) showed that indomethacin blocked arterial contraction mediated by acetylcholine (ACh). The objective of this study was to determine if contraction induced by acetylcholine is mediated by the cyclooxygenase pathway in s...

Immediate postoperative evaluation of enteric anastomosis after the use of meloxicam in rats

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE : To compare ileal anastomoses in the immediate postoperative healing period after meloxicam use. 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...
