ABSTRACT
Background: Recently, much attention has been directed towards considering activated microgelial cells as putative targets for treatment of neurological disorders. MigriHeal as a novel herbal remedy was introduced for the treatment of migraine headaches. The previous researches has shown that MigriHea extracts can decrease NO in an in vitro inflammatory model. The aim of this study was to investigate the effect of MigriHeal on NO generation from LPS- stimulated microglia cells
Materials and Methods: Neonatal rat primary microglial cells were isolated from the mixed glial cultures and the purity of the cultures was determined by immunocytochemistry. Microglial cells were pretreated with Migri-Heal and activated by 1microg/ml LPS. Subsequently, NO levels in the culture supernatants were measured by a griess reaction. Our results showed that Migri-Heal 50microg/ml significantly reduced NO level in inflamed microglia in a dose-dependent manner
Results: The results showed that different concentrations of Migri-Heal had no prominent effect on cell viability in presence of LPS as compared with the control group. In addition, the pretreatment of microglia cells with Migri-Heal can prevent from a morphological changes of the cells into the round and phagocytic shape
Conclusion: Our study demonstrated that MigriHeal might have NO scavenging properties. Integrative studies are warranted to uncover the novel pharmacological insights of this herbal remedy as an putative therapeutic approach against diseases -associated with inflammation
