[Localization of alcohol and aldehyde dehydrogenases in the human spinal cord and brain].
Location of aldehyde dehydrogenase (AldDG) and alcohol dehydrogenase (ADG) has been studied in 38 nuclei of the human brain. Neurons with a high AldDG activity predominate in the nucleus of the descending root of the trigeminal nerve, motor nuclei of the craniocerebral nerves (trigeminal, facial, abducent, blocking, sublingual, supraspinal), motor nuclei of the anterior horns of the spinal cord, lateral vestibular nucleus, posterior nucleus of the vagus nerve, pedunculopontine nucleus, superior salivary nucleus, and in the nucleus of Westphal-Edinger-Jacobovich. Neurons with a moderate AldDG activity predominate in the superior olivary complex, nucleus of the lateral loop, parabrachial (pigmented) mesencephalic nucleus and reticular lateral nucleus. A low enzymatic activity is specific for neurons of the pons proper, inferior vestibular nucleus, trapezoid body of the inferior olivary complex, dentate nucleus of the cerebellum, reticular nucleus of the tegmen of Bekhterev's pons and posterior nucleus of Gudden's suture. A high ADG activity is revealed in piriform neurons of the cerebellar cortex. Functional importance of ADG and AldDG activity in the brain is discussed.
