Abstract

Swiss CDl mice died less than 2 h after intraperitoneal injection of 420 mug/kg of algal yessotoxin (YTX). The morphological, histochemical and immunocytochemical studies performed on the cerebellar cortex revealed damage to the Purkinje cells. The main cytological alterations were observed in the cytoplasm, while less sufferance was detected in the nucleus. The immunocytochemical experiments showed an increased positivity to S100 protein while there was a decreased response to calbindin D-28K, beta-tubulin and neurofilaments. These changes in intracellular Ca2+-binding proteins and the modifications in the cytoskeletal components of Purkinje cells suggest that YTX may be involved in neurological disorders.
