Effects of perinatal stress and drug abuse on maternal behavior and sensorimotor development of affected progeny

Popis výsledku v původním jazyce

Methamphetamine (MA) is an addictive psychostimulant with significant potential for abuse. Previous rat studies have demonstrated that MA use during pregnancy impairs maternal behavior and induced delayed development of affected pups. The offspring of drug-addictive mothers were often neglected and exposed to neonatal stressors. The present study therefore examines the effect of perinatal stressors combined with exposure to prenatal MA on the development of pups and maternal behavior. Dams were divided into three groups according to drug treatment during pregnancy: controls (C); saline (SA, s.c., 1 ml/kg); MA (s.c., 5 mg/ml/kg). Litters were divided into four groups according to postnatal stressors: controls (N); maternal separation (S); maternal cold-water stress (W); maternal separation plus cold-water stress (SW). The pup-retrieval test showed differences among postnatally stressed mothers and non-stressed controls. The righting reflex on a surface revealed delayed development of pups prenatally exposed to MA/SA and postnatal stress. Negative geotaxis and Rotarod results confirmed that the MA group was the most affected. Overall, our data suggests that a combination of perinatal stress and prenatal MA can have a detrimental effect on maternal behavior as well as on the sensorimotor development of pups. However, MA exposure during pregnancy seems to be the decisive factor for impairment.
