Abstract
Calcitonin gene related protein (CGRP) is increased in both lesional and non-lesional psoriasis. The role of CGRP in the pathogenesis of psoriasis vulgaris is still not clear. We designed to determine the CGRP-I (or CALCA), II (or CALCB) gene expression and morbidity and CALCA T-692C single-nucleotide polymorphism (SNP). Peripheral blood mononuclear cells (PBMCs) and plasma samples were collected, and CGRP level and CGRP-I, II mRNA expression were measured in psoriasis patients and healthy controls. The CALCA T-692C genetic polymorphism in psoriasis and control subjects was also compared. A higher expression of CGRP-I, II mRNA in PBMCs in psoriasis patients. The plasma CGRP level in psoriasis patients was also higher than that in healthy subjects. SNP analysis showed carriers of the T-692C allele were over-represented in non-drinking Patients. The plasma CGRP level was higher in alcohol-drinking patients with TT genotype than that with TC genotype. The plasma CGRP level is increased in psoriasis patients and CALCA T-692C polymorphism TT genotype is a factor for the affectability in alcohol-drinking Psoriasis vulgaris patients.

Abstract
A U-Pb zircon age of 1762 +/- 11 Ma is reported for granite gneiss located on Flinders Island, South Australia, This age is identical, within analytical uncertainty, to a previously reported age for schists of the Price Metasediments located 100 km to the southeast on the southwestern coast of the Eyre Peninsula. The outcrop represents the only known country rock to the Early Mesoproterozoic Calca Granite (Hiltaba Suite) of Flinders Island, the largest island of the Investigator Group of islands, in the southwestern Gawler Craton. The stratigraphic name Investigator Granite Gneiss is proposed for this rock unit. The discovery of the Investigator Granite Gneiss now considerably increases the extent of known Late Palaeoproterozoic rocks on the eastern side of the peninsula. The outcrop was previously included with the considerably younger St Peter Suite granite-monzogranite, and grouped together with other islands in the Investigator Group. This new dating suggests that the geology on the other islands may require revision, For the first time, detailed major and trace-element geochemistry is supplied for the granite gneiss on Flinders Island.
