title: Effect of tetraethyl lead and restricted food intake on locomotor activity in the rat.
abstract: The effect of tetraethyl lead (TEL) and restricted food intake on spontaneous locomotor activity in male albino rats was investigated. Forty animals were injected intraperitoneally with 4, 7, 10 or 13 mg/kg body weight of TEL in peanut oil, or a peanut oil placebo. Forty additional animals were food yoked to lead treated animals as a control procedure to hold food intake constant between lead treated and lead free animals. A comparison of pre- and posttreatment measures revealed significant decreases in food intake and increases in activity levels at dosages of 7, 10 and 13 mg/kg of TEL. In addition, food intake and activity were significantly correlated in both lead treated and yoked groups. The issue of factors associated with reduced food intake playing a role in observed activity level increases was raised.
