Melatonin was shown to produce a tocolytic effect in experiments on the isolated uterine horn in different experimental animals and on the whole body. The ability of melatonin to inhibit uterine contractility was confirmed by the studies of the effects of melatonin on oxytocin-induced myometrial contractions. It may be suggested that the antagonism between melatonin and oxytocin is uncompetitive.

The effects of glycosamine aminosugar on the processes of endotoxicosis and lipid peroxidation were thoroughly studied in rats with toxic pulmonary edema. There was a glycosamine-induced decrease in markers of endotoxicosis, such as medium-weight molecular peptides and malonic dialdehyde in serum and lung tissue. Administration of exogenous glucosamine resulted in its incorporation into the membranes of target organs, connective tissue and normalized the levels of endogenous N-acetyl-glucosamine, which finally determined antitoxic and antioxidative properties in this aminosugar.
The albino rat experiments studied the pharmacological action of oxycinnamic acid derivatives in acute tetrachloromethane-induced hepatic dystrophy and combined CCl4-ethanol-induced hepatic lesion. The tested agents were found to produce cholagogic, membrane-protective, and antioxidative effects in these hepatic abnormalities, thus improving the functional (cholate- and glycogen-synthetic) parameters of the liver.
