BACKGROUND Evidence of an association between multiple sclerosis (MS) and other autoimmune diseases would substantiate the hypothesis that MS is an autoimmune disease, and implicate a common mechanism. We aimed to investigate and compare the rate of autoimmune disease in MS patients, in their first-degree relatives, and in their unrelated spouses. METHODS(More)
BACKGROUND AND PURPOSE Genetic and environmental factors have important roles in multiple sclerosis (MS) susceptibility. Given a potential role for sex hormones in MS, we have investigated whether or not the age of puberty influences the risk of developing MS in a population-based cohort. METHODS We identified 5493 MS index cases and 1759 spousal controls(More)
The rat urinary bladder is one of the few in vivo preparations in which kinin B1 receptor-mediated contractile responses have been described, but the nature (local or reflex) of these responses has not been characterized. We have investigated the motor effects of i.v. or topical (onto the bladder serosa) administration of the selective kinin B1 receptor(More)
Substance P (SP) and neurokinin A (NKA) are synthesized by enteric cholinergic motorneurons that project to the longitudinal and circular muscle of the mammalian intestine. Thus, acetylcholine, SP, and NKA are the excitatory neuromuscular transmitters in the intestine. Tachykinin NK1 and NK2 receptors are expressed by smooth muscle cells in most regions of(More)
The aim of this study was to assess at which extent an even co-release of the tachykinins, substance P (SP) and neurokinin A (NKA), occurs from enteric neurons/nerves of the guinea-pig proximal colon during graded depolarization. In this preparation, a sharply diverging NK1/NK2 receptor pattern of tachykininergic co-transmission has been observed in(More)
This study investigates the role of tachykinin NK1 and NK2 receptors in motor responses induced by the intravesical instillation of capsaicin in urethane-anaesthetized rats. SR 140,333 (1 micromol/kg, i.v.), a nonpeptide NK1 receptor antagonist, abolished urinary bladder contractions induced by the selective NK1 receptor agonist [Sar9]SP-sulfone (0.1-100(More)
We have used [3H]Senktide, a selective Neurokinin B receptor ligand, for the characterization of NK-3 receptors in rat and guinea pig CNS membranes. Scatchard analysis of saturation binding studies in cerebral cortex membranes indicated that this ligand bound to a single site with apparent high affinity (KD = 4.6 +/- 1.6 and 3.1 +/- 0.37 nM, Bmax = 13.7 +/-(More)
BACKGROUND There is a strong maternal parent-of-origin effect in determining susceptibility to multiple sclerosis (MS). One hypothesis is that an abnormal intrauterine milieu leading to impaired fetal development could plausibly also result in increased susceptibility to MS. A possible marker for this intrauterine insult is the presence of a non-fatal(More)
