UF-1000i: validation of the body fluid mode for counting cells in body fluids.

Background: We evaluated the new body fluid mode on the UF-1000i urinalysis analyzer for counting total white blood cells (WBC) and red blood cells (RBC) in continuous ambulatory peritoneal dialysis (CAPD), ascites and pleural fluids.

Methods: We collected 154 body fluid samples, and compared the results of the UF-1000i BF mode with the Fuchs-Rosenthal counting chamber and the XN-1000 BF mode. Linearity, carry over and precision were also assessed.

Mechanisms underlying cerebellar motor deficits due to mGluR1-autoantibodies.

Patients with Hodgkin's disease can develop paraneoplastic cerebellar ataxia because of the generation of autoantibodies against mGluR1 (mGluR1-Abs). Yet, the pathophysiological mechanisms underlying their motor coordination deficits remain to be elucidated. Here, we show that application of IgG purified from the patients' serum to cerebellar slices of mice acutely reduces the basal activity of Purkinje cells, whereas application to the flocculus of mice in vivo evokes acute disturbances in the performance of their compensatory eye movements.
