Abstract:
:The reduction in growth resulting from lead (PB) exposure in weanling rats is consistent with a lowering of the biological set-point for food intake. In this study the effects of lead on the patterns of food intake were examined. For 10 days (from ages 26 to 36 days), female rats were provided with drinking water containing 250 ppm lead as the acetate (n = 6) or equivalent acetate as sodium acetate (n = 6). A computerized system was used to monitor daily food intake at 5-min intervals over 10 successive 23-h periods (each period consisting of 12 h dark, 11 h light). Control rats consumed approximately 75% to 85% of their food intake during the dark phase. Exposure to lead resulted in decreased body weight, tail length, and cumulative food intake. Decreased food intake associated with lead during the first 6 days of exposure was due to a decrease in the size of each meal during the dark phase, which reflected a decrease in the duration of each meal. These results suggest that lead, at least initially, was affecting food-satiety signals to produce a premature termination of food intake during a meal. After 6 days, the lead-exposed rats appear to have adjusted their meal size and meal duration to approximately control values. However, this compensation appears to have occurred at the expense of the daily (nocturnal) number of meals, which decreased slightly (although not significantly) in lead-exposed animals. Thus, the total daily intake of food in lead-treated animals remained depressed relative to control animals.
