The aim of the present work was to evaluate in an early time point the effect of the cannabinoid agonist WIN 55,212-2 after hypoxic-ischemic (HI) brain injury induced by partial occlusion of the umbilical cord of premature fetal lambs. Lambs were assigned to three experimental groups: one SHAM group: non-injured animals, and two hypoxic-ischemic groups that received a dose of 0.01μg/kg WIN 55,212-2 (HI+WIN group) or not (HI+VEH) after 60min of a hypoxic-ischemic event.

Unlabelled: The aim of this work was to evaluate the effect of magnesium sulphate (MgSO4) administration on blood-brain barrier (BBB) permeabilization after cerebral hypoxia-ischemia (HI) induced by partial occlusion of the umbilical cord of premature fetal lambs. We also characterized BBB dysfunction in terms of the levels of expression of a panel of BBB proteins; Occludin, Claudin, Zona Occludens-1, Zonula Occludens-2, VE-cadherin and beta-catenin. Lambs were assigned to:

Control Group: non-injured animals, 0 h post-partial cord occlusion (0h-PCO) group: animals subjected to 60 min HI and sacrificed just after the insult, 3h-PCO group: HI injured animals resuscitated and managed on ventilation for 3 hours and MgSO4 group: animals which received a dose of 400 mg/kg MgSO4 after the HI event and managed on ventilation for 3 hours.

Our aim was to develop a computerized system for real-time monitoring of lung mechanics measurements during both gas and liquid ventilation. System accuracy was demonstrated by calculating regression and percent error of the following parameters compared to standard device: airway pressure difference (Delta P(aw)), respiratory frequency (f(R) ), tidal volume (V(T)), minute ventilation (V'(E)), inspiratory and expiratory maximum flows (V'(ins,max), V'(exp,max)), dynamic lung compliance (C(L,dyn) ), resistance of the respiratory system calculated by method of Mead-Whittenberger (R(rs,MW)) and by equivalence to electrical circuits (R(rs,ele)), work of breathing (W(OB)), and overdistension. Outcome measures were evaluated as function of gas exchange, cardiovascular parameters, and lung mechanics including mean airway pressure (mP(aw)).

To test the neuroprotective effects of the nonpsychoactive cannabinoid cannabidiol (CBD), piglets received i.v. CBD or vehicle after hypoxia-ischemia (HI: temporary occlusion of both carotid arteries plus hypoxia).
