ABSTRACT:
The aim of the study was to investigate the effect of repeated administration of 5-Hydroxytryptophan (5-HTP) on pain sensation. The quantity of 5-HTP reaching the Central Nervous System (CNS) is affected by the extent to which 5-HTP is converted to serotonin in the periphery. The formalin test was used to access pain perception using two groups of mice weighing 22g-32g (n=10 each).The control group received (15g) normal rodent chow, while the test group received (15g w/w) 5-HTP diet. Daily food intake, water intake and body weight change were measured. The results in the formalin test, showed that the frequency and duration of paw attention and paw lick in both phases of the test was significantly lower (P< 0.05) in the 5-Hydroxytryptophan group (5-HTP) compared to the control. Therefore, repeated administration of 5-Hydroxytryptophan diet decreases pain perception in mice.
