(Journal of Ethnopharmacology, 1994-06-01) [Artigo]
Extracts of Acanthospermum hispidum and Cajanus cajan have been used by Brazilian people in an attempt to produce abortion. In order to evaluate the possible abortive and/or teratogenic effect of these plant extracts, ...
PRESYNAPTIC AND POSTSYNAPTIC MECHANISMS INVOLVED IN TETANIC FADE INDUCED BY PANCURONIUM IN THE ISOLATED RAT MUSCLE
(Pharmacology, 1994-10-01) [Artigo]
The mechanisms underlying the fade of the tetanic contraction induced by pancuronium were studied in vitro by means of myographical and electrophysiological techniques in the extensor digitorum longus muscle of the rat. ...
Alcohol levels in cerebrospinal fluid and blood samples from patients under pathological conditions
(Acta Neurologica Scandinavica, 1992-01-01) [Artigo]
We measured alcohol levels by the Cordebard method in 148 CSF samples from individuals who had abstained from alcohol for at least 7 days prior to the beginning of the study. Each blood sample was accompanied by a CSF ...
Antagonism produced by hypertonic nutrient solutions on the depressive effect of carbofuran on isolated guinea pig atria
(Pharmacological Research, 1996-04-01) [Artigo]
The action of hyperosmotic nutrient solutions on the depressive effects of carbofuran was studied on spontaneously contracting guinea pig atria. The force and frequency of contraction were recorded using an isotonic lever. ...
Chronic mild prenatal stress exacerbates the allergen-induced airway inflammation in rats
(Mediators of Inflammation, 1999-06-03) [Artigo]
The effects of chronic mild prenatal stress on leukocyte infiltration into the airways was investigated in rat offspring. The chronic prenatal stress consisted of transitory and variable changes in the rat's living conditions. ...
Functional effects of castration on alpha(1)-adrenoceptors in rat vas deferens
(European Journal of Pharmacology, 1998-06-19) [Artigo]
The effects of castration on alpha(1)-adrenoceptors in rat vas deferens were investigated by determining the actions of selective antagonists against the contractions induced by noradrenaline. The results obtained in vas ...

(Naunyn-schmiedebergs Archives of Pharmacology, 1998-01-01) [Resumo]
PHARMACOLOGICAL EVALUATION OF THE INHIBITORY EFFECT OF EXTRACTS FROM ANCHIETIA-SALUTARIS ON THE HISTAMINE-RELEASE INDUCED IN THE RAT AND THE GUINEA-PIG
(International Archives of Allergy and Immunology, 1994-01-01) [Artigo]
The tea made with leaves and stems of plant Anchietia salutaris is traditionally used in Brazil to treat allergies. We examined the effects of a crude aqueous extract and of purified fractions of this plant on the histamine ...
POSSIBLE MECHANISMS FOR REDUCTION OF CIRCULATING CONCENTRATIONS OF PROGESTERONE BY INTERFERON-ALPHA IN COWS - EFFECTS ON HYPERTHERMIA, LUTEAL CELLS, METABOLISM OF PROGESTERONE AND SECRETION OF LH
(Journal of Endocrinology, 1992-05-01) [Artigo]
Experiments were performed to determine the mechanism by which recombinant bovine interferon-alpha(I)1 (rbIFN-alpha) causes an acute reduction in plasma concentrations of progesterone. In experiment 1, administration of a ...
Does the male reproductive performance depend on the early lactation milk in rats?
(Physiology and Behavior, 1996-01-01) [Artigo]
This study investigated the role of the early lactation milk (ELM) on the male reproductive performance and the participation of GnRH on this effect in Wistar rats. Newborn males were divided into three experimental groups: ...
