[Oxidative processes in tissues of the nematode Mecistocirrus digitatus]

The tissues of the nematode M. digitatus were used to obtain mitochondria which swell under the effect of several factors. Intensive oxidation of succinate, fumarate, malate, oxalacetate, alpha-ketoglutarate and less intensive one -- of citrate, isocitrate and pyruvate were observed in the mitochondria; cis-aconitate was not oxidized at all. NAD and NADP increased the intensity of substrate oxidation, whereas parachlormercuribenzoate, malonate and benzoate decreased the latter.
