The purpose of this study was to trace the immunoreactivity of the two calcium binding proteins, parvalbumin and calbindin D28k, in the periaqueductal gray matter of the chinchilla midbrain. The immunoreactivity of these proteins in this species has never been investigated. The localisation of the activity was examined by carrying out the peroxidase-antiperoxidase (PAP) reaction using specific antibodies against parvalbumin and calbindin D28k. Slightly different parvalbumin immunoreactivity was shown. In most neurons, with the exception of large neurons in the dorsal and dorso-lateral periaqueductal gray matter, a weak immunostaining for parvalbumin was observed. Extremely intense immunostaining for calbindin D28k occurred in all neurons in the examined area. The results obtained suggest a slightly different distribution of parvalbumin in the neurons of the periaqueductal gray matter of the midbrain of the chinchilla than in other animal species. This indicates that mainly calbindin D28k is involved in the regulation of intracellular calcium ion concentration in the periaqueductal gray matter of the chinchilla.

Immunohistochemical study of the cholinergic innervation of the hippocampal cells containing glutamic acid decarboxylase (GAD) and calcium binding proteins: parvalbumin (PV), calbindin D28k (CB) and calretinin (CR) was conducted on 5 adult rat brains. Analysis of sections with double immunostaining for vesicular acetylcholine transporter (VAChT; the marker of cholinergic cells, fibres and terminals) and respectively either GAD or PV, CB, CR, using confocal laser-scanning microscope shows that the intensive cholinergic innervations receive GAD, PV and CB-positive hippocampal cells. Cholinergic afferentations of the CR-positive neurones are considerably fewer.
