The types of neurons in the claustrum of bison bonasus: Nissl and Golgi study.

The Nissl staining and Golgi impregnation methods has been used to characterize the types of neurons in the claustrum of bison bonasus. Two fairly divergent subpopulations of cells can be distinguished by means of Golgi preparation technique. The first group--comprising the bulk of claustral neurons--is composed of only one type of large, efferent nerve cells with long axons and dendrites covered with spines. The somata and initial portion of dendritic processes are devoid of spines. The second group consists of large and medium-size interneurons with smooth infrequently branching dendrites. Amongst them two sub-populations can be observed: with dendritic swellings and with dendrites deveoid of them. In Nissl stained sections the claustral neuronal population consists of large multipolar cells among which fewer large or medium-size, spindle-shaped cells are dispersed. The multipolar cells and also spindle-shaped neurons contain widely distributed, deeply-stained, medium-sized pigment granules. No orderly alignment of cells can be seen.

The types of neurons in the neostriatum of bison bonasus. Nissl and Golgi study.

The caudate nucleus and the putamen of bison bonasus have been investigated. The Golgi procedure and Nissl stain had been used to reveal their cellular organization. In the Golgi preparation striatal neurons belong to the two fairly divergent main groups in which several types of cells can be distinguished. The first class, comprising the bulk of neuronal population, consists of only one type of efferent cells with the long axons. The spines cover dendrites except its proximal portion. The second one is composed of four types of interneurons which perikarya and dendritic processes are devoid of spines: aspiny neurons with tortuous dendrites, aspiny cells with dendritic swellings, large aspiny nerve cells, and long-axoned neurons with sparsely distributed but regularly branching dendritic processes.

Improved cleansing for colonic radiography.

A well tolerated regimen utilizing Phosphosoda and X-Prep Liquid effectively cleanses the bowel prior to x-ray examination. Good to excellent visualization was achieved in 89.3 per cent of the patients involved in the study.
