The incorporation of [3 H]fucose in the somatotrophic and gonadotrophic cells of the rat adenohypophysis has been studied by electron microscope autoradiography to determine the site of synthesis of glycoproteins and to follow the migration of newly synthesized pituitaries were fixed 5 min, 20 min, 1 h, and 4 h after the in vivo injection of [3 H]fucose and autoradiographs Cited by: Indeed, in the rat, growth of this tissue occurs after hypophysectomy, with an increase in the number and size of functioning gonadotropes. to Second, knowledge of the distribution of cell types in the adenohypophysis makes it possible to predict the sites of small functioning pituitary tumors.

V Soil-Based Discovery of Novel Esterases and Lipases. Esterases and lipases are subclasses of the hydrolase superfamily of enzymes. Lipases have been historically differentiated from esterases by their ability to hydrolyze glycerol esters of long-chain fatty acids, as well as being enzymatically activated at the lipid–water interface.
The bacterial lipases⧸esterases encompass a large superfamily of enzymes. Species and tissue differences in the activity of three major classes of esterases, carboxylesterase (CE), butyrylcholinesterase (BChE) and paraoxonase (PON), were studied.
Substantial species differences in activity of these esterases were observed between the mouse, rat, dog monkey and human. On continuation of study by Kurz and Goslar () concerning the inhibitory effects to non specific esterases on liver and kidney, the behaviour of α-naphthyl-acetate-esterases on hypothalamus, neurohypophysis, adrenal and parotid glands of rats had been examined against aldehydes, organic solution-mediators and anorganic salts.

The uptake of L-dopa into the cells of the adenohypophysis of the rat was studied during the postnatal development and at adult age using the formaldehyde-induced fluorescence method (FIF). The cells taking up L-dopa were classified by Alcian blue-PAS-Orange G staining. The correlation between the cells taking up L-dopa and those containing tryptophyl-peptide was estimated during the Cited by: 4.
The adenohypophysis (anterior pituitary) is a major centre for systemic hormones. At present, no efficient stem-cell culture for its generation is available, partly because of insufficient Cited by: The adenohypophysis consists of 3 parts: the pars distalis, pars tuberalis, and pars intermedia.
In many species, the adenohypophysis completely surrounds the pars nervosa of the neurohypophyseal system. The pars distalis is the largest region of the adenohypophysis and contains the multiple populations of endocrine cells that secrete the different pituitary trophic hormones.
The investigation of in vitro plasma metabolism of ester prodrugs is an important part of in vitro ADME assays during preclinical drug development. Here, we show that the in vitro metabolism including plasma stability and metabolizing enzymes of curcumin diethyl disuccinate (CDD), an ester prodrug of curcumin, in dog and human plasma are similar but markedly different from those in rat plasma.
