Popis: Purified tetanus toxin (TT), in experiments in vitro, was shown to affect neither the Na,K-ATPase activity of the synaptic membrane fraction of the rat cerebral cortex nor the inhibition of Na,K-ATPase activity produced by electrical stimulation of a suspension of synaptic membranes, nor the binding of GABA-3H by synaptosomes. TT and colchicine (1 mM) reduced the osmotic sensitivity of the nerve endings. Colchicine, in low concentrations (10−5 to 10−3 M), does not affect Mg- and Na,K-ATPase but, in higher concentrations (10−2 M), it inhibits the activity of both ATPases considerably.
