Abstract

The dimethyl-xanthine derivative pentoxifylline (PTX) increases blood flow through capillaries. In elderly humans the drug leads to improvement in a number of imapired neuropsychological parameters. We now report that oral administration to 29-month female mice (C57, black and tan) over six days induced four different patterns of behavioural reponse: (1) consistent improvement in grooming behaviour throughout the six day trial; (2) significant improvement in light/dark zone curiosity and curiosity towards a strange object on day three, which declined but remained significantly above pre-treatment levels at day 6; (3) an improvement in general activity which only becomes detectable on day six; (4) a significant improvement in rod-walking, rearing an shuttle-box crosses on day three which returned to pre-treatment levels by day 6. Age-related deficits in general activity, grooming and curiosity were completely eliminated by the drug - the mean group performance levels attained those seen in 9-12 month individuals of this strain.
