The humanization of care in childbirth and the choice of performing cesarean or vaginal delivery have long been discussed in Brazil and worldwide. The complexities of the factors surrounding this issue range from the quality of obstetric care through to the significance of childbirth for women. A new proposal for humanization of delivery was introduced by the Brazilian Ministry of Health, the objectives of which were to make changes to the current system of delivery practices regarding, access, care, quality and resolution, in order to make it a more human and less technical experience.

Calcium channel blockade as a target for the cardiovascular effects induced by the 8 (17), 12E, 14-labdatrien-18-oic acid (labdane-302).

The cardiovascular effects induced by labdane-302, a diterpene isolated from the stems of Xylopia langsdorffianna St. Hill and Tull, were evaluated in male Wistar rats. In normotensive, conscious animals, labdane-302 produced dose-dependent hypotension and tachycardia.

N-salicyloyltryptamine, a new anticonvulsant drug, acts on voltage-dependent Na+, Ca2+, and K+ ion channels.

1. The aim of this work was to study the effects of N-salicyloyltryptamine (STP), a novel anticonvulsant agent, on voltage-gated ion channels in GH3 cells. 2.
