Mechanism of Action of the Thyroid Hormone on the Heart
SUMMARY The foliowing cardiac effects may be attributed to thyroxin: 1-Thyroxin augments all anaerobic processes in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...
متن کاملAntibacterial Activity of Polypyrrole-Chitosan Nanocomposite: Mechanism of Action
Polypyrrole-chitosan nanocomposite (PPy-CTN) was synthesized by dispersion polymerization of PPy in presence of CTN. Preparation of spherical PPy nanoparticles that were successfully covered with a thin layer of chitosan was confirm by transmission electron microscopy (TEM) technique. Characterization techniques also revealed the presence of CNT in the polymer matrix and its presence was confir...
متن کاملMechanism of Action of Gonadotropin II. COSTROL OF OVARIAN NUCLEAR RIBONUCLEIC ACID POLYMERASE ACTIVITY AND CHROMATIK
The role of RNA synthesis was investigated in the action of chorionic gonadotropin on ovaries of immature rats. Chorionic gonadotropin accelerates the ovarian incorporation of [3H]uridine in uivo into rapidly labeled nuclear RNA within 10 min after hormone injection. Analysis of the RNA base composition, expressed as base ratio (A + U):(G + C), shows that hormonal stimulation of the rate of [3H...
متن کاملMechanism of action of gonadotropin-releasing hormone. Involvement of phospholipid turnover in luteinizing hormone release.
The action of gonadotropin-releasing hormone (GnRH) upon luteinizing hormone (LH) secretion is calcium-dependent, but is not mediated by cyclic AMP, cyclic GMP, or prostaglandins. The role of calcium-mediated phospholipid turnover in GnRH action was investigated in 2-day cultured pituitary cells, in which the production and target cell effects of arachidonic acid were analyzed in relation to Gn...
متن کاملStudy on Antinociceptive Activity of Different Extracts of Peganum Harmala and Possible Mechanism of Action
The seeds of Peganum harmala L. ( Pgh ) (Zygophyllaceae) have been used in Moroccan traditional medicine for treatment of a various diseases and to relieve dolorous process. The major objective of this paper was to investigate the analgesic effect of ethyl acetate (EAE), butanolic (BE) and aqueous (AqE) extracts of seeds of Peganum harmala and elucided the possible underlying action mechani...
