The effect of gamma-butyrolactone (GBL) on the accumulation of dopa after inhibition of aromatic amino acid decarboxylase was studied in rats following chronic treatment with ethanol. The GBL-induced dopa accumulation was significantly decreased in ethanol-treated rats. With the increased duration of the ethanol treatment this effect appears to be more marked in the limbic forebrain. It is suggested that chronic ethanol treatment may produce a decreased sensitivity of central GABA receptors.
在对大鼠进行乙醇慢性处理后,研究了γ-丁内酯(GBL)对芳香族氨基酸脱羧酶抑制后多巴积累的影响。在乙醇处理的大鼠中,GBL诱导的多巴积累显著减少。随着乙醇处理时间的延长,这种效应在边缘前脑似乎更为明显。提示慢性乙醇处理可能导致中枢GABA受体敏感性降低。
