THE EFFECT OF IODINE DEFICIENCY ON ~3H-LEUCINE INCORPORATION INTO CEREBRUM AND CEREBELLUM DURING DEVELOPMENT OF THE BRAIN / 营养学报

The study was made on 3H-leucine incorporation into brain of offsprings born by their mothers who were fed in severe iodine deficiency area. Control group received an iodine-supplemented diet (1.7mg KIO3/kg food). Disintegration per minute (dpm) was used as an index to assess the 3H-leu-cine incorporation rate in comparision of the two groups.The results of 3H-leucine incorporation into brain showed that the dpm/mg of brain cortex and cerebellum was significantly lower in experimental group than that of control group at the time of 1-14 hours after injection of the preparation on 11-day offsprings (p
