Abstract:
The effects of NMDA and quiscalate on proliferation of primary cell cultures of human glioma, rat estrogen induced pituitary tumor and mouse spleen lymphocytes were investigated in vitro. The tritiated thymidine incorporation into DNA was used as an index of cell proliferation. Neither NMDA nor quiscalate affected the tritiated thymidine incorporation in the cell cultures herein studied. This finding contradicts the idea of the involvement of EAA receptors in the control of cell proliferation although does not exclude it.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
