Measurements were made on the diameter and length of the capillaries of the turtle hypophysis. The volume and surface of vessels were calculated and compared with those of the cat, frog, and salamander. Only the anterior lobe showed vessels which were significantly wider than in the adjacent brain tissue. The surface area of blood in the anterior and tuberal lobes is very extensive, 17 sq. mm. to 18 sq. mm. for 1 cu. mm. of fresh tissue, and is between two and three times as great as in the other lobes and in the richest centers of the brain. The vascular surface in each lobe, except the intermediate one, is lower than, but shows similar variation to, that of the cat. The pars nervosa is supplied by vessels between it and the pars intermedia as in the salamander and is unlike that of the frog or cat with numerous vessels penetrating its substance.

Peripheral Sympathetic Nervous System

Cytochemical methods for the localization of central catecholamine-containing synaptic terminals have been developed from an extensive foundation of biochemical work and from extrapolation of results on the peripheral sympathetic nervous system. Direct localization of catecholamines in central nerve terminals in some parts of the brain can now be obtained by fixation with permanganates. More broadly applicable, but less direct localizing methods depend upon selective accumulation of tritiated catecholamines for autoradiography or the accumulation of reactive catecholamine congeners which act as markers with conventional fixation. The pattern of acute degenerative changes which result after treatment with 6-hydroxydopamine can also be used to provide an indirect localization of the terminals which had stored catecholamines. When the results of each of the methods are combined, the present techniques indicate that catecholamine-containing terminals in the brain can be identified more confidently than any other system of neurotransmitter substances. Nevertheless, there is considerable need for future cytochemical innovation.
