Angioarchitecture of the anterior and medium parts of the palatine mucosa of the gerbil, Meriones unguiculatus.

The aim of this study was to examine the microvasculature of the anterior and medium portions of the hard palatine mucosa in the adult gerbil (Meriones unguiculatus) using scanning electron microscopy. The vascular corrosion casts were obtained by injection of Mercox CL-2B synthetic resin and tissue corrosion was performed using sodium hydroxide solution. These casts revealed the presence of capillary loops in the palatine plicae and a smoother/flatter vascular network in the interplicae areas.

Effects of alcohol consumption on osseointegration of titanium implants in rabbits.

Alcohol consumption affects bone metabolism by impairing osteoblast proliferation and by increasing osteoclastic activity. The purpose of this study was to evaluate bone formation in alcohol-fed rabbits following the insertion of dental titanium implants. Animals were fed with 20% ethanol sugarcane brandy pre- and postoperatively (group 1), preoperatively only (group 2), and with water as control (group 3).

Perivascular injury leads to a reduction in vascular reactivity of the collared and to an enhancement on contralateral carotid artery of rats.

Background: The first response to perivascular injury is observed in the adventitial layer. The purpose of this study was to determine the time course of vascular reactivity alterations after collar injury in rats. We also analyzed the relation between adventitial layer injury and vascular responsiveness to vasoconstrictor agents.
