Early administration of fibrinogen concentrate in patients with polytrauma with thromboelastometry suggestive of hypofibrinogenemia: A randomized feasibility trial.

Objective: To evaluate the clinical effects of early administration of fibrinogen concentrate in patients with severe trauma and hypofibrinogenemia.

Methods: We conducted an open randomized feasibility trial between December 2015 and January 2017 in patients with severe trauma admitted to the emergency department of a large trauma center. Patients presented with hypotension, tachycardia, and FIBTEM findings suggestive of hypofibrinogenemia.

Aminophylline (a theophylline-ethylenediamine complex) blocks ethanol behavioral effects in mice.

Aminophylline is a complex of theophylline-ethylenediamine, where theophylline is the main component. Theophylline is a methyxanthine and besides inhibiting phosphodiesterase enzymes, it is also a nonselective adenosine antagonist. Several reports suggested the involvement of the brain adenosinergic system in the ethanol-induced motor incoordination.

Determination of amino acid levels in the rat striatum, after administration of ethanol alone and associated with ketamine, a glutamatergic antagonist.

The main goal of this study was to determine the amino acids (glutamate, aspartate, glutamine and tyrosine) levels in the rat striatum, after ethanol administration alone and/or associated with ketamine. In protocol 1 (Et+ketamine-1), ethanol was administered to male Wistar rats until the 7th day, and at the next day the group received only ketamine (25mg/kg, i.p.

Anticonvulsant activity of hydroalcoholic extracts from Erythrina velutina and Erythrina mulungu.

The anticonvulsant effects of hydroalcoholic extracts (HAEs) from the stem bark of Erythrina velutina and Erythrina mulungu on pentylenetetrazole (PTZ) and strychnine-induced seizure tests and the potentiation of pentobarbital-induced sleeping time in mice with the extracts were examined in this study. These medicinal plants belong to the Fabaceae family and are popularly used in Brazil for their effects on the central nervous system. The extracts of Erythrina velutina (intraperitoneally or orally) and Erythrina mulungu (intraperitoneally) were administered in mice at single doses (200 or 400mg/kg).
