High-dose injections of aminoglycoside antibiotics can produce a blockade of the muscle junction, which is manifested by weakness of the extremities. Dyspnea or
NA is an a receptor agonist, a larger dose can constrict renal blood vessels, reduce renal blood flow, resulting in a decrease in urine output; furosemide is a
Epinephrine alone has a pressor effect, while alpha-blockers can reverse its pressor effect. Barium chloride can promote the inward flow of sodium ions in the P
Sulfonamides and compounds with free amino groups on the benzene ring undergo diazotization with sodium nitrite in acidic solutions to produce diazonium salts,
In pharmacology experiments, there are many factors affecting the experimental results, some of which can be controlled, while some are difficult to control. In

Solubility-action relationship experiments with barium salts can be used to study the effect of the physicochemical properties of a drug on its action.
The purpose of this experiment was to observe the differences in the effects of different doses of sodium pentobarbital on mice. After the administration of the
Barium chloride induces arrhythmias by increasing the inward Na+ current in Purkinje fibers and increasing the depolarization rate of the maximal diastolic pote
The rabbit isolated aortic strip assay can be used to observe the effects of drugs on the diastolic and contractile functions of vascular smooth muscle. Observa
