Different Levels

Some authors using immunofluorescent techniques had already suggested that some hepatocytes are able to synthetize several plasma proteins. In vitro studies on normal cells or on cells issued of murine hepatomas raise the same conclusion. These works could be indications of an hepatocyte functionnal non-specialization, meanwhile the authors never give direct topographic proofs suitable with this hypothesis.The use of immunoenzymatic techniques after obtention of monospecific antisera had seemed to us useful to bring forward a better knowledge of this problem. We have studied three carrier proteins (transferrin = Tf, hemopexin = Hx, albumin = Alb) operating at different levels in iron metabolism by demonstrating and localizing the adult rat hepatocytes involved in their synthesis.Immunological, histological and ultrastructural methods have been described in a previous work.

SummaryThe results of thyroid function tests have been compared with data on the thyroxine-binding capacity of plasma proteins in hyper-, hypo- and euthyroid cases, the latter including women taking oral contraceptives (Infecundin). It was found that there exists a significant correlation of exponential nature between the in vitro red blood cell 125I-triiodothyronine uptake (RCU) and the free thyroxine-binding capacity of the thyroxine-inding globulin (TBG).

Test Conditions

SummaryRabbits were injected with 75Se-Methionine (75SeM) 4-8 hr after being subjected to a variety of experimental conditions: injection of ACTH, growth hormone, glucagon, adrenalin, endotoxin, turpentine, hydrocortisone and laparotomy. All of these experimental conditions except injection of glucagon were associated with increased incorporation of 75SeM into fibrinogen. Three patterns of incorporation of 75SeM into plasma proteins were recognized: 1. the pituitary pattern, which was observed in animals injected with ACTH, growth hormone or endotoxin, and which was characterized by increased incorporation of 75SeM only into fibrinogen and by a delayed incorporation of 75SeM into α2 and β1 globulins; 2. the tissue injury pattern, which was characterized by a markedly increased incorporation of 75SeM into fibrinogen and no alteration in incorporation of 75SeM into α2 or β1 globulins; and 3. the pharmacologic corticosteroid pattern, which was characterized by a moderately increased incorporation of 75SeM into fibrinogen and a strikingly increased incorporation of 75SeM into α2 and β1 globulins.
