Abstract

The rough handling with repeated saline administration (1.2 ml/kg s.c. for 7 days) enhanced cortical c -fos mRNA expression in the rat brain after a single saline stimulation (1.2 ml/kg s.c.) due to increasing baseline c -fos mRNA levels, whereas the gentle handling with repeated saline administration declined c -fos mRNA expression after a single injection due to decreasing the baseline of c -fos mRNA levels. These two types of handling with the repeated injection led to diametrically opposite results on c-fos mRNA expression after a single stimulation. Neither two types of handling with repeated saline injections affected the net increment of c-fos mRNA induction after a single stimulation, therefore, the effects of handling with repeated treatment on c-fos mRNA expression might be independent of the effects of a single saline stimulation. The present study suggests that c-fos mRNA induction after a single stimulation might be affected by the types or intensities of handling and that care must be taken to estimate c-fos mRNA induction.
