The aim of this study, was to determine plasma biochemical parameters such as alkalen phosphatase (AP), aspartate amino transferase (AST), lactate dehydrogenase (LDH), gama glutamyl transferase (GGT), total protein (TP), albumin (ALB) and lipid peroxidation levels in the horses with urticaria at pre- and post-treatment period.

In this study 17 standardbred horses with urticaria were used. Blood samples were collected in all horses from the jugular vein directly into vacutainer tubes, plasma was seperated by centrifugation and stored at -20ºC until analysis. Plasma biochemical parameters were determined with an autoanalyser using commercial test kits. Lipid peroxidation levels were determined according to the method of Placer.

There were no significant differences in plasma AP, AST, LDH, GGT, TP and ALB levels between pre- and post-treatment periods, but lipid peroxidation levels were significantly different (p<0.05).
