Male Wistar rats (380-430 g) were immunized with bovine serum albumin conjugated with dopamine (2 mg/kg, 0.25 ml) mixed with Freund's adjuvant complete (0.25 ml) or with bovine serum albumin mixed with Freund's adjuvant complete in the same doses. One week after the immunization with bovine serum albumin conjugated with dopamine, irregular spike activity and high-amplitude spindles associated with the state of awake immobility were recorded in the rat neocortex and caudate putamen, the relative power of the electrical activity in the caudate putamen was decreased in the alpha band, while the relative power of the beta 1 in the cortical EEG was increased. In the structure of 4-hour diurnal sleep, a decrease in the mean duration of sleep episodes and a reduction in the REM sleep content were observed. The parameters of the electrical activity and diurnal sleep structure returned to normal during the following 4 weeks. The open-field behavior 2 weeks after the second immunization (without Freund's adjuvant complete) did not differ from that of the control rats immunized only with bovine serum albumin. Titres of antibodies to dopamine after the second antigen injection were 1:32-1:64 in the electrophysiological series and 1:128-1:256 in behavioral experiments. |
