The histochemistry of the neural cells was studied in the submandibular ganglia of 5 Callithrix jacchus (3 males and 2 females) and 4 Callithrix penicillata (2 males and 2 females). These cells contain neutral mucopolysaccharides, nucleoproteins and lipidic material, but are apparently devoid of glycogen. It was impossible to demonstrate in them any reactivity for UDPG-GT, phosphorylases, ATPase at pH 6.3, leucine aminopeptidase and alanyl amino-peptidase. The reaction for the other searched enzymes was as follows: weak (F-16-P Aid and cytochrome oxidase), weak to moderate (ADH, 6-P-GDH, ICDH, SDH, MDH, α-GPDH and β-OHBDH), moderate (G-6-PDH, F-1.6-PA, LDH and GDH), moderate to strong (ATPase at pH 7.4, nonspecific esterase and acid phosphatase) and strong (G-6-PA, NADH2-TR, NADPH2-TR, ATPases at pH 8.5 and 9.4 and alkaline phosphatase).
Histoenzymologic differences between the parotid, paramandibular and submandibular glands were studied in six Callithrix jacchus (four males and two females) and four Callithrix penicillata (three males and one female). The acinous cells of the paramandibular glands showed a stronger reactivity for the diaphorases (NADH2-TR and NADPH2-TR) and for a certain group of enzymes of the carbohydrate metabolism (F-1–6P Aid, LDH, ADH, G-6-PDH and 6-PGDH), lipid metabolism (α-GPDH, β-OHBDH, alkaline phosphatase and acid phosphatase), protein metabolism (alanyl aminopeptidase, leucine aminopeptidase and GDH) and respiratory chain (β-aconitase and ICDH). The nonspecific esterase was more reactive in the basal part of the mucous cells of the submandibular glands. Conversely, some enzymes of the respiratory chain (SDH, cytochrome oxidase and ATPases) showed a stronger reactivity in the serous cells of the parotid and submandibular glands. The paramandibular glands exhibited a lesser autonomic innervation than the parotid and submandibular.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
