    ..By contrast, the anxiolytic effect of caffeine in a dose of 100 mg/kg (not observed under normal conditions) develops after this treatment. ..

    ..The level of food motivation remains practically unchanged with an increase in the ratio of pressing episodes to 16 and 32 (despite consumption of food). ..

    ..Since administration of these solutions cannot produce maximum blood concentration of ethanol, we believe that the observed effects are mainly related to the direct effect of ethanol on the stomach tissue. ..

    Sudakov S, Bogdanova N. Activation of Peripheral ?-Opioid Receptors Normalizes Caffeine Effects Modified in Nicotine-Dependent Rats during Nicotine Withdrawal. Bull Exp Biol Med. 2016;161:743-745 pubmed
    ..In its turn, inhibition of central ?-opioid structures activates the brain adenosine system, which can attenuate the caffeine-induced effects in nicotine-dependent rats. ..

    ..A similar effect of the drugs was observed in the previous models. More complex effect of nicotine on the risk behavior may be explained by the absence of severe food motivation typical for the early models. ..

    ..Thus, the state of gastric opioid receptors affects the manifestation of ethanol-induced analgesia and the development of tolerance to this effect. ..
