Background: While color Doppler ultrasonography and microvascular Doppler recordings have been used intraoperatively for spinal cord vascular malformations, they have not been employed for similar spinal cord lesions preoperatively.

Case Description: We report the usefulness of color Doppler ultrasonography through a lumbar laminectomy defect in the management of a spinal arteriovenous fistula.

Conclusion: Color Doppler ultrasonography should be considered for spinal lesions in which a laminectomy defect is present.

Light microscopic immunohistochemistry coupled with freeze-substitution electron microscopic immunocytochemistry was used to localize alpha-subunits of G-proteins and type III adenylyl cyclase in developing rat olfactory epithelia. Some cilia immunoreacted with antibodies to GS alpha and type III adenylyl cyclase as early as prenatal day 15 (E15; E1 = sperm-positive), but immunolabelling with antibodies to Golf alpha was not observed until E16. From then on numbers of receptor cells with immunolabelled cilia increased for all three probes.
