Occlusal disharmonies have classically been thought to be involved in the etiopathogenesis of bruxism, as have, more recently, alterations in central neurotransmission, particularly dopaminergic neurotransmission. However, the connection between these two factors has still not been established. In this study, we assessed the effects of diverse occlusal(More)
A case of acquired von Willebrand disease (AvWD) associated with an IgA lambda multiple myeloma is reported. No form of inhibitor could be detected. SDS-agarose gel electrophoresis patterns of von Willebrand factor (vWF) both in plasma and platelet lysates were normal but a decrease in all-sized multimers with a type IA pattern was seen. After 1-deamino-8-D(More)
N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4) induces a degeneration of noradrenergic axons originating in the locus coeruleus. The sensitivity of alpha2-adrenoceptors which regulate the synthesis and release of noradrenaline was investigated in three brain regions which receive an unequal innervation from locus coeruleus, 21 days after DSP4 (50(More)
It is thought that the expression of oral parafunctions may provide an outlet for stress or aggressiveness in man. Stress-induced increases in central noradrenergic neurotransmission are attenuated in rats which are allowed to bite during stress. Striatal dopaminergic neurotransmission is involved in the genesis of parafunctional oral movements in rodents.(More)
Fractionation of an anti-inflammatory extract from Cayaponia tayuya roots yielded two active compounds, identified as 23,24-dihydrocucurbitacin B (1) and cucurbitacin R (2). Both were evaluated for their anti-inflammatory activity on several experimental models of pain and inflammation. In addition, their cytotoxicity and effects on leukotriene B4 (LTB4)(More)
The sensitivity of alpha(2)-adrenoceptors which regulate synthesis and release of noradrenaline was investigated in hippocampus, parietal cortex, and hypothalamus of rats treated with clorgyline. After administering a DOPA decarboxylase inhibitor, the in vivo tyrosine hydroxylase activity and the noradrenaline content were evaluated. Acute and chronic(More)
