In this article the authors clinically compare the efficacy of two different anti-inflammatory drugs - Etoricoxib (Arcoxia®) and Diclofenac (Olfen®) – in the control of postoperative pain resulting from the surgical removal of impacted lower third molars. Fifteen patients requiring the extraction of bilaterally impacted lower third molars were selected at the Department of Oral and Maxillofacial Surgery at the Araraquara School of Dentistry – UNESP. The drugs were randomly administered during the first and second surgical procedures. Pain was evaluated by means of a visual analogic scale for 72 hours following the surgical procedure. After statistical analysis of the results, the authors concluded that there were no significant differences in terms of postopoerative pain control between the two drugs studied.

Aims: Inflammation may have an important role in the beginning and in the progress of cardiovascular diseases. Testosterone exerts important effects on vascular function, which is altered in arterial hypertension. Thus, the aim of this study was to evaluate the influence of endogenous testosterone on leukocyte behavior in post-capillary venules of the mesenteric bed of spontaneously hypertensive rats (SHR). Main methods: 18 week-old intact SHR, castrated SHR and normotensive rats (intact Wistar) were used. Blood pressure was measured by tail plethysmography and serum testosterone levels by ELISA. Leukocyte rolling, adhesion and migration were evaluated in vivo in situ by intravital microscopy. Key findings: Castration significantly reduced blood pressure and reversed the increased leukocyte rolling and adhesion observed in SHRs. Leukocyte counts and other hemodynamic parameters did not differ among groups. SHRs displayed increased protein expression of P-selectin and ICAM-1 in mesenteric venules when compared to intact Wistar. Castration of SHRs restored the protein expression of the cell adhesion molecules. Significance: The findings of the present study demonstrate the critical role of endogenous testosterone mediating the effects of hypertension increasing leukocyte-endothelial cell interaction. Increased expression of cell adhesion molecules contribute to the effects of endogenous testosterone promoting increased leukocyte rolling and adhesion in SHRs. (c) 2012 Elsevier Inc.
