Effects of cyclobeximide, puromycin and actinomycin D on the spontaneous motility of isolated rat uterus
The effect of cycloheximide (2 μg/ml), puromycin (2 μg/ml) and actinomycin D (1 μg/ml), as well as the relation between the influence of cycloheximide and prostaglandin (PG) production on the spontaneous motility of 20 days-ovariectomized rat uterus, were studied. Cycloheximide evoked a more stable...

| Sumario: | The effect of cycloheximide (2 μg/ml), puromycin (2 μg/ml) and actinomycin D (1 μg/ml), as well as the relation between the influence of cycloheximide and prostaglandin (PG) production on the spontaneous motility of 20 days-ovariectomized rat uterus, were studied. Cycloheximide evoked a more stable motility during the experimental period (180 min) when compared with controls. Neither puromycin nor actinomycin D could madify the spontaneous activity. In the presence of cycloheximide, the rat uterus released more PGE-like material than the untreated one, and no differences were found in the generation of PGF-like material. Indomethacin, acetylsalicylic acid and eicosa-5,8,11, 14- tetraynoic acid could partially block the cycloheximide-induced constancy of motility of uterine strips. Cyproheptadine and atropine had no effect at all. It is suggested that cycloheximide prevents the spontaneoys decay of the contractile activity at least in part by influencing PGE-like material production. © 1982 The Italian Pharmacological Society. |
