OBJECTIVE To determine the effects of autologous fibrinogen (AF) and absorbable barrier membrane (ABM) on periodontal healing of canine experimental grade-III furcation defects. ANIMALS 18 conditioned, laboratory-source, adult Beagles. PROCEDURE Defects were developed bilaterally at the second and fourth premolars and maintained for 12 weeks. Defects were treated with AF, ABM, AF and ABM, o...

Background: GABAergic drugs can modulate the rewarding properties of morphine. The objective of this study was to evaluate the effects of isoniazid, as a GABAergic agent, on the rewarding effects of morphine. Methods: Eighteen groups of female mice (eight per group) were used in a conditioned place preference (CPP) study. On the conditioning phase of the CPP p...

BACKGROUND The blood brain barrier (BBB) and truncated trkB receptor on astrocytes prevent the penetration of brain derived neurotrophic factor (BDNF) applied into the peripheral (PNS) and central nervous system (CNS) thus restrict its application in the treatment of nervous diseases. As BDNF is anterogradely transported by axons, we propose that peripherally derived and/or applied BDNF may act...

Regeneration of injured adult sensory neurons within the CNS is essentially abortive, attributable in part to lesion-induced or revealed inhibitors such as the chondroitin sulfate proteoglycans and the myelin inhibitors (Nogo-A, MAG, and OMgp). Much of this inhibition may be overcome by boosting the growth status of sensory neurons by delivering a conditioning lesion to their peripheral branche...

OBJECTIVES Exposing a hind leg of a rat to vibration induces an injury to the sciatic nerve--a so called conditioning lesion. After such injury induced by vibration the regenerative capacity of the nerve is improved and can be detected as an increased axonal outgrowth from a test crush lesion to the same nerve. The purpose was to study whether the effect of a conditioning lesion induced by vibr...

Colchicine, a potent neurotoxin derived from plants, has been recently introduced as a degenerative toxin of small pyramidal cells in the cortical area 1 of the hippocampus (CA1). In this study, the effect of the alkaloid in CA1 on the behaviors in the conditioning task was measured. Injections of colchicine (1,5 μg/rat, intra-CA1) was performed in the male Wistar rats, while the animals were s...
