Mechanism of Action of Stinging Nettles

Stinging nettles for osteoarthritis pain of the hip.

Cnidarian internal stinging mechanism.

Stinging mechanisms generally deliver venomous compounds to external targets. However, nematocysts, the microscopic stinging organelles that are common to all members of the phylum Cnidaria, occur and act in both external and internal tissue structures. This is the first report of such an internal piercing mechanism. This mechanism identifies prey items within the body cavity of the sea anemone...

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...

Antibacterial 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...
