Abstract

The effects of exposure to different concentrations of phenoxyherbicides and their metabolites were studied in human erythrocytes, with particular attention to catalase (CAT—EC. 1.11.1.6— hydrogen peroxide: hydrogen peroxide oxidoreductase). 4‐chloro‐2‐methylphenoxyacetic acid (MCPA), 2,4‐dimethylphenol (2,4‐DMP) and 2,4‐dichlorophenoxyacetic acid (2,4‐D) did not affect CAT activity, but 2,4‐dichlorophenol (2,4‐DCP) and 2,4,5‐trichlorophenol (2,4,5‐TCP) decrease its activity, the latter being the more inhibitory.

The levels of serotonin (5-HT), 5 hydroxyindoleacetic acid (5-HIAA), dopamine (DA), homovanillic acid (HVA), norepinephrine (NE), and tyrosine hydroxylase (TH) activity were measured in the focus (spiking) and nonfocus (nonspiking) regions of the temporal neocortex of 20 patients with intractable co
