Choline acetyltransferase activity and weight of salivary glands in rats at different ages. 1976

J Ekström

The choline acetyltranferase activity underwent marked changes during the life span: in the submaxillaries, the total enzyme activity increased 70-fold from birth up to the age of 3 months and it then remained constant throughout the rest of the observation period, i.e. up to 28-29 months; in the parotids, in contrast, it continued to rise beyond the age of 3 months and the highest value was reached at 24 months. The weights of the glands increased markedly up to 3 months. The gain in weight was less pronounced thereafter.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012469	Salivary Glands	Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).	Gland, Salivary,Glands, Salivary,Salivary Gland
D013363	Submandibular Gland	One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur.
