The inhibition by citrinin (CTN) of lipid peroxidation of mitochondria, sub-mitochondrial particles (SMP) and microsomes was studied. This eect was reversed by the presence of high concentrations of Fe 3 (0 . 4 and 0 . 5 mM), suggesting chelation of the mycotoxin with iron or interference in the red

The eects of citrinin in the maintenance of the homeostasis of the reactive oxygen species in rat liver cells were evaluated. Citrinin (CTN) modi®es the antioxidant enzymatic defences of cells through the inhibition of GSSGreductase and transhydrogenase. No eect was observed on GSH-peroxidase, catal

The effects of the mycotoxin citrinin on renal cortical and liver mitochondrial swelling were studied. Citrinin decreases the rate of swelling induced by the valinomycin-K+ complex, suggesting that the mycotoxin interferes with the mitochondrial membrane fluidity. Citrinin promotes reduction of the

Citrinin depresses the phosphorylation efficiency of rat renal cortical mitochondria, as inferred from the decrease of the respiratory control coefficient (RC) and ADP/O ratios. The transmembrane potential (A+) developed by energized mitochondria and the depolarization upon ADP addition are also dec

## Abstract The electrolyte distribution and sugar uptake by teased renal tubules of winter flounder (__Pseudopleuronectes americanus__) was studied using incubation media with 1.4 mM Ca^2+^ (controls) and without Ca^2+^. The omission of Ca^2+^: (a) produced some cellular swelling, and increase in
