Interleukin-1 receptor antagonist gene polymorphism in Taiwanese patients with gout.

OBJECTIVE: The purpose of this study was to examine whether interleukin-1 receptor antagonist (IL-1Ra) gene polymorphism is a marker of susceptibility to or of the clinical characteristics of gout in Taiwanese patients. METHODS: 196 Taiwanese patients with gout and 103 unrelated normal healthy control subjects living in central Taiwan were studied. Polymorphism of the gene for IL-1Ra was typed from genomic DNA. Allelic frequencies and carriage rates were compared between gout patients and control subjects. The relationship between IL-1Ra genotypes and the clinical characteristics of gout was also evaluated. RESULTS: No significant differences were observed in genetic and allelic frequencies of the IL-1Ra gene polymorphism between patients with gout and healthy control subjects. Furthermore, we did not detect any association of IL-1Ra genotype with the clinical and laboratory profiles in patients with gout. CONCLUSION: The results from the present study suggest that the interleukin-1 receptor antagonist gene polymorphism is not a genetic marker of susceptibility to gout for Taiwanese. Furthermore, our study also suggests that the IL-1Ra gene polymorphism is unrelated to the clinical characteristics of gout.

Neuropharmacological studies on identified central neurones of the snail, Helix aspersa.

Central neurones of the snail, Helix aspersa, possess both synaptic and somatic receptors to a wide range of classical transmitters and neuroactive peptides. The range of receptors and the type of response is reasonably constant for a specific neurone. This review will provide data concerning the pharmacology of acetylcholine, serotonin, dopamine, noradrenaline, octopamine, glutamate, GABA and purine receptors on identified neurones. Many of these neurones also respond to neuroactive peptides including molluscan peptides, e g, AMPMLRLamide, LSSFVRIamide, SGQSWRQGRPFamide, FMRFamide; coelenterate peptides, e g, pQGRFamide; echinoderm peptides, e g, GFNSALMFamide; and nematode peptides, e g, KNEFIRFamide, KHEYLRFamide, SDPNFLRFamide. Using this data, the pharmacological profiles of identified neurones will be summarised.
