Properties and effect of Ittar in mice behavior and neurological functions

Fragrances are generally synthetic, natural or a combination of both. Ittar or Attar is a natural fragrance material synthesized from plants which were majorly used by people worldwide as a matter of pride, deodorization and attractant. The effect and role of using Ittar on mammalian system is still not known at the behavioral and neurological level. This study was aimed to understand the constituents and the effect of Ittar on mice by measuring their behavioral and neurological changes upon exposure to Ittar. Batches of animals were exposed to ten different types of Ittar for 1, 2 and 3 weeks respectively. Behavior of the animals exposed to the Ittar perfumes were analyzed against the control animals behavior for physiological activities. Also, the expression level of neurotransmitter such as Dopamine, 5-HIAA, HVA and Serotonin were evaluated based on HPLC analysis. Based on this study it was found that all the ten Ittars were different for its different constituents with some basic overlapping molecules among them. The neurotransmitter such as DOPA, 5-HT, Homovanillic Acid and Serotonin were found non-significantly increased in the total brain after a three week long continuous exposures of Ittar to the animal. Histological analysis of the ittar exposed mice skin showed mild to massive changes in both epidermal and dermal layers characterized with intense infiltration of inflammatory cells, hyperplasia, hyperchromasia and edema formation against control animals in few of the Ittars. From this study it is evident that Ittar increases mood of the animal through the up-regulation of various neurotransmitter but subtle effect on the skin because of the presence of various chemical constituents of the Ittar. Based on this study it is evident that use of Ittar as fragrance might be beneficial at the molecular level and it will be appropriate to apply without direct exposure to skin.
