正当父母们想着终于可以从抚育孩子的重担下解脱出来时，许多大学应届毕业生会选择在领了学位证书后——卷席回家。就算不回家与父母同住，也有可能要继续靠他们接济过日子；就如美国HBO电视台热播的电视剧《女孩们》一开始的剧情那样... 详细信息

正当父母们想着终于可以从抚育孩子的重担下解脱出来时，许多大学应届毕业生会选择在领了学位证书后——卷席回家。就算不回家与父母同住，也有可能要继续靠他们接济过日子；就如美国HBO电视台热播的电视剧《女孩们》一开始的剧情那样，由莉娜·杜汉所扮演的女孩汉娜就极力希望父母继续给她生活费。美国经济不景气使得这种“成长延缓”的现象继续恶化，令美国人到了二十几岁甚至三十出头还得多年依靠家人支持。

Journal of Behavioral and Brain Science 2021年第8期11卷 179-192页

Aim: Δ9-Tetrahydrocannabinol (Δ9-THC) is a potentially addictive cannabinoid. Its impact on the activity of liver arylamine N-Acetyltransferase (NAT) has not been reported. This study investigated the rewarding effects of Δ9-THC in mice and whether Δ9-THC had any impact ex-vivo and in-vitro on NAT activity. Methods: Thirty-six Swiss albinomice randomly assigned to six groups (n = 6) completed a biased, 8-week Conditioned Place Preference (CPP) paradigm. Mice exhibiting ~80% preference for the black chamber at pre-conditioning were selected. Treatment groups were administered Δ9-THC (0.10, 0.50 or 2.0 mg/kg/mL, ip) or amphetamine (AMP, 5.0 mg/kg/mL, ip);while untreated groups (controls) received vehicle solutions (coconut oil or 0.9% saline). Entries and time spent in the white, drug-paired chamber during a 15-min post-conditioning exploration of the CPP apparatus were compared with the pre-conditioning exploratory scores. Livers from Δ9-THC treated and untreated mice were excised and NAT enzyme activity determined ex-vivo using a spectrophotometric assay with p-anisidine as substrate. The impact of varying concentrations of Δ9-THC (0.00 - 162 μM) on the activities of NAT from untreated mice livers were also investigated in-vitro. Results: Δ9-THC treated mice entered and spent significantly more time in the drug-paired CPP chamber (p ≤ 0.05) at post-conditioning vs pre-conditioning (f = 11.22). Mice treated with 2.0 mg/kg Δ9-THC made significantly more entries into the drug-paired chamber (p ≤ 0.05) as compared with their vehicle controls. AMP-treated mice displayed significant (p ference). In-vitro NAT evaluations revealed a dose-dependent inhibitory impact of Δ9-THC on NAT
