| Abstract: | Three neurotoxin fractions have been isolated from the venom of the spider Anemesia sp. On interacting with a presynaptic membrane, two of them (An4 and Any) caused an enhancement of the secretion of the mediator and exhaustion of its reserves, while the third (An7) caused suppression of the amplitude of the synaptic potentials.Institute of Physiology and Biophysics, Academy of Sciences of the Republic of Uzbekistan, 700095, Tashkent, ul.
