A possible control of food intake during pregnancy in the XXXX .

1. @entity75 concentrations of @entity750 and @entity1063 have been implicated in the control of food intake. During pregnancy and lactation a @entity35 dam's food consumption is increased and so a study was performed to ascertain whether this was associated with changes in the @entity1640 content of @entity750 and @entity1063 . 2. In the first experiment, forty-eight @entity35 dams were given a diet containing 250 g casein/kg adlib. After 2 weeks, eight were killed and their hypothalmic analysed for the previously-mentioned neurotransmitters. The rest were mated and continued on the diet. On each of days 7, 14 and 20 of gestation, day 14 of lactation and 2 weeks after weaning of their pups a further eight dams were killed and their hypothalami assayed as described previously. Food intake was monitored throughout the experimental period. 3. The increase food intake of the dams during gestation and lactation increased to the same extent as elevation in @entity1640 @entity1063 content and @entity308 in @entity750 content. After lactation food intake returned to pre-pregnancy levels as did the @entity1640 levels of @entity1063 and @entity750 . 4. By using the same experimental design but limiting the increase in food intake in pregnancy and lactation to half the expected amount the same changes were found in @entity1640 @entity1063 and @entity750 contents. 5. The possibility of @entity1640 neurotransmitter contents controlling food intake is discussed.
