Abstract/OtherAbstract:
The effects of oestrogen and progesterone on noradrenergic nerves and nerves with serotonin (5-HT)-like immunoreactivity in the basilar artery were investigated in the rabbit using whole-mount stretch preparations. The noradrenergic nerves were demonstrated by glyoxylic acid fluorescence histochemistry and nerves with 5-HT-like immunoreactivity by indirect immunofluorescence techniques. Quantitative image analysis of fluorescent nerve fibres revealed that nerve density and varicosity diameter of nerves with 5-HT-like immunoreactivity were significantly (P less than 0.01 and P less than 0.05 respectively) reduced after 4-week administration of oestrogen and the intensity of fluorescence was also reduced. However, there were no significant changes after progesterone. Neither oestrogen nor progesterone had any effect on noradrenergic innervation. The findings are discussed in relation to higher incidence of migraine headaches in females taking oral contraceptives.
