The blood pressure, heart rate, ACTH, corticosteroid, vasopressin, and renin responses to rapid 15 ml/kg hemorrhage were measured in six conscious healthy dogs with chronically maintained femoral arterial catheters. The hemorrhage decreased the mean arterial blood pressure slightly (P less than
Microvascular failure is a major determinant for the development of hepatocellular dysfunction after hemorrhagic shock. Induction of heme oxygenase (HO) 1 may confer hepatocellular protection. Hemin arginate (HAR) induces HO-1 and protects against shock-induced organ failure. The mechanisms are not
BACKGROUND
Induction of heme oxygenase-1 (HO-1) protects the liver against reperfusion injury after hemorrhagic shock. Previous data suggest that the beta(1)-adrenoceptor agonist dobutamine induces HO-1 in hepatocytes.
OBJECTIVE
To investigate the functional significance of dobutamine pretreatment
The diurnal rhythm of plasma melatonin was studied in 46 Chinese patients with acute cerebral hemorrhage. The state of consciousness of each patient was assessed clinically. The individual sites of lesion were determined by computerized tomography scanning. One to five days after stroke, blood
A 47-year-old man was found dead in a factory where dichloromethane (DCM) tanks were stocked. He was making an inventory of the annual stock of DCM contained in several tanks (5- to 8000-L capacity) by transferring the solvent into an additional tank with the help of compressed air. During this
A 22-year-old white male was found dead at his working place in a car lacquering company. He had removed lacquer residues by using a solvent containing dicloromethane (DCM) without using a gas mask. Pathology revealed signs of asphyxiation with obvious petechial bleedings and expressed
The use of nonsteroidal antiinflammatory drugs in racehorses is allowed under most jurisdictions. Furosemide is administered to treat exercise-induced pulmonary hemorrhage. To help distinguish between therapeutic and illegal uses, racing regulatory bodies have set thresholds in serum for several
BACKGROUND
Snakebite is considered a neglected tropical disease by the World Health Organization. In Brazil, about 70% of the envenomation cases are caused by Bothrops snakes. Its venom may provoke hemorrhage, pain, necrosis, hemolysis, renal or cardiac failure and even death in victims. Since
UNASSIGNED
Anani, (Symphonia globulifera, Clusiaceae), known as chewstick, is a traditional plant occurring in Africa and in Central and South Americas that is used against parasites and microorganisms. Although its use is popular in some of these countries, there is a lack of information related to
Snake venom is composed of a mixture of substances that caused in victims a variety of pathophysiological effects. Besides antivenom, literature has described plants able to inhibit injuries and lethal activities induced by snake venoms. This work describes the inhibitory potential of ethanol,
OBJECTIVE
To determine the gastroprotective and antisecretory effect of ethanol extract from matico leaves (Piper aduncum) in animal models.
METHODS
To evaluate the gastroprotective effect, 220 mice of the Balb C57 strain were used. They were randomized in 22 groups of ten animals each, in which the
BACKGROUND
Renealmia alpinia has been traditionally used to treat snakebites by indigenous Embera-Katíos tribes belonging to the regions of Antioquia and Chocó, Colombia, and it has been shown to inhibit the enzymatic and biological activities of Bothrops venoms and their purified phospholipase A2
OBJECTIVE
Within the genus Scutellaria various species are used in different folk medicines throughout Asia. Traditional Chinese Medicine (TCM) uses S. baicalensis (Labiatae) to treat various inflammatory conditions. The root shows strong anticancer properties in vitro and was suggested for clinical
The haemorrhagic dengue fever affects up to 500 million patients, annually causing 20.000 deaths, with no chemotherapeutic agent available. The oleoresin labdanum of Cistus creticus L. has been established as an anti-infective agent since antiquity in Mediterranean
