title: Histochemical distribution of acid mucopolysaccharides during circadian rhythm in the cerebellum of Serranus scriba.
abstract: Histochemical analysis of AMPS (AB-staining materials) in Serranus scriba brain showed its irregular distribution in different brain regions. The highest AMPS content was observed in the optocoele and ependymal cells lining it, above the marginal telencephalon and optic tectum as well as the molecular cerebellum layer. Particularly significant AMPS concentrations were noted in Purkinje cell regions. The telencephalon and optic tectum showed AB-negative-staining materials. Following histochemical changes during a 24 h period, AMPS concentrations were shown to follow circadian variations, especially in the Purkinje cell region. The highest AMPS content was noted during the morning and the lowest during the evening hours. The above changes were discussed in the context of the role of AMPS in neural functions.
