Abstract:

BACKGROUND: Olfactory bulb neurogenesis, transformation and maturation have been considered the hot topic. Olfactory bulb experience and nervous activity can influence olfactory bulb neurogenesis. However, no study reports that olfactory bulb functions can affect olfactory bulb neurogenesis in guinea pigs.
OBJECTIVE: To investigate the effect of unilateral olfactory functional deprivation on doublecortin, calbindin and parvalbumin expression in olfactory bulb of juvenile guinea pigs.
METHODS: Totally 24 guinea pigs were randomly divided into two groups, which were killed after establishing olfactory functional deprivation model through electric cautery injury at the left peripheral nostrils. At 3 and       6 weeks after modeling, the specimens were harvested. The expression change of doublecortin, calbindin and parvalbumin in two sides’ olfactory bulb of juvenile guinea pigs was detected by immunohistochemistry.
RESULTS AND CONCLUSION: The number of doublecortin, calbindin and parvalbumin positive cells in olfactory bulb at the un-deprived side was significantly higher than that at the deprived side at 3 and 6 weeks (P < 0.05). This finding indicates that olfactory neural activities can affect neurogenesis and transformation in guinea pigs.
