Kinetics of photoconductivity of viper venom (Macrovipera lebetina obtusa Linnaeus, 1758) depending on storage period

In order to study both the electrophysical parameters and photoconductivity of zootoxin, the temperature dependence of the resistivity (ρ) of the crystalline viper venom was studied. At the same time, a “sandwich” structure was created for further study of the electrophysical parameters of the viper’s venom. Presents data on the detection of kinetics and photoconductivity of the venom of the viper (Macrovipera lebetina obtusa Linnaeus, 1758) depending on the storage period. For this purpose, whole venom of the Transcaucasian viper (Macrovipera lebetina obtusa) and dried in a desiccator over calcium chloride vapor, collected in 1993 were subjected to photoconductivity studies in 2008. Were a study of the temperature dependence of the resistivity ρ for the crystalline snake venom of Macrovipera lebetina obtusa was carried out. The snake venom sample was heated in a measuring cell at a constant rate of 9.1°C/sec. The resistance was measured with an E6-13A teraohmmeter. It has been experimentally established that viper venom crystals are not photosensitive in the wavelength range 0.2 µm–2 µm. We assume that under the influence of external factors (in our case, under the influence of temperature), a change in the electrophysical parameters of snake venom is noted. The photoconductivity of snake venom crystals was studied depending on the heating temperature of the crystals in the wavelength range 2 µm - 4 µm. It was revealed that viper venom has photoconductivity in the wavelength range 2 µm – 4 µm. We assume that after each subsequent heating, structural changes may occur in the poison sample under study and, in turn, changes in both toxicity and pharmacological activity of enzymes are noted.
