We estimated the efficacy of Brizantin preparation in suppressing nicotine dependence in rats. It was shown that nicotine-dependent rats in the situation of choice between the chamber with smoke or the chamber with food more frequently entered the chamber with tobacco smoke and stayed there longer. The rats that received Brizantin demonstrated significantly fewer visits to the chamber with smoke and spent there less time. Reduced locomotor activity and orientation and exploratory behavior in rats against the background of Brizantin administration also suggest reduced motivation for smoke inhalation. Thus, Brizantin effectively diminished nicotine dependence in rats in the model of nicotine addiction.
We studied the effect of morphine hydrochloride, brain-specific S100 protein, and antibodies to morphine, S100 protein, and opiate mu-receptors in ultralow doses on self-stimulation of the lateral hypothalamus in morphinized rats. This reaction in morphine-withdrawn rats underwent specific changes after single administration of test preparations. Repeated treatment with preparations in the same dose equalized emotional homeostasis. This effect was especially pronounced after treatment with antibodies to morphine, S100 protein, and opiate mu-receptors. Our findings should be taken into account in developing methods for non-narcotic substitutive therapy of patients with morphine dependence.
Effect of potentiated antiserum to brain-specific protein S100 in a concentration of 10 -'~176 prepared according to standard homeopathic procedures on integrative activity ot ~ rat brain was studied on models of conditioned avoidance reaction and self-stimulation of the lateral hypothalamus through chronically implanted electrodes. The antibodies reversibly inhibit memory processes during avoidance reaction. The incidence of the self-stimulation reaction increased after single administration of potentiated antibodies, while their administration for 5 days decreased the incidence of this reaction. Administration of water caused no such effects.
We studied the effect of potentiated antibodies to morphine (10(-100) wt %) on self-stimulation of the lateral hypothalamus and behavioral reactions reflecting the severity of withdrawal syndrome in rats with morphine dependence. Repeated treatment with potentiated antibodies to morphine increased the rate of self-stimulation, suppressed active avoidance response, promoted freezing behavior after acoustic stimulation, and decreased tail-flick latency in rats after morphine withdrawal. Distilled water did not produce these changes.
We studied the effects of morphine and its potentiated form on nociceptive thresholds in rats with the morphine withdrawal syndrome. Repeated combination (bipathic) treatment with morphine and its potentiated form increased nociceptive threshold and, therefore, activated the nociceptive system in the brain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
