tannic acid/hemorrhage

OBJECTIVE To investigate the effects of tannic acid pretreatment on cardiovascular function during hemorrhagic shock in rats. METHODS Sprague-Dawley (SD) rats were randomly divided into two groups of shock and tannic acid pretreatment+shock. (1) In vivo experiment: the model of hemorrhagic shock in

The plant natural products namely tannic acid and the flavonoids luteolin, kaempferol and apigenin exerted potent inhibition on the hyaluronidase enzyme. They were able to neutralize the haemorrhage induced by Crotalus adamenteus venom in mice dose-dependently from 0.12-2.4 mg/kg subcutaneously. In

Sclerotherapy with aluminum potassium tannic acid (ALTA), which was approved in Japan for the treatment of internal hemorrhoids in July 2004 (Takano et al., Int J Colorectal Dis 21:44-51, 2006), has been widely accepted because of its effectiveness and low invasiveness. More than 200,000 patients

OBJECTIVE Injection sclerotherapy for hemorrhoids has been performed for many years. Currently, 5% phenol in almond oil (PAO) and aluminum potassium sulfate and tannic acid (ALTA) are used as the agents. The purpose of this study was to compare the efficacy of the two agents. METHODS A retrospective

Reversed passive hemagglutination (RPHA) tests were performed by coating glutaraldehyde-fixed and tannic acid-treated sheep erthrocytes with antibodies to Rift Valley fever (RVF) and Crimean-Congo hemorrhagic fever (CCHF) viruses. Cells coated with crude antibody, in the form of mouse immune ascitic

Massive blood loss and bacterial infection are major challenges for global public health. However, traditional wound dressings cannot fully meet the current clinical needs in controlling bleeding and avoiding infection. In this study, we prepared a chitin nanofiber suspension by green mechanical

Adhesive hydrogels for wet and dynamic tissues are important for biomedical applications in order to withstand cyclic loading such as in the case of hemorrhaging control on the curved skins and heart tissues. However, the fabrication of hydrogels with strong mechanical properties, high adhesion

Acute tannic acid intoxication was studied in mice and sheep. In mice, following oral administration of 2.0 to 4.6 g of tannic acid kg-1 bodyweight, periacinar coagulative and haemorrhagic necrosis occurred in the liver. In sheep, following oral (8 g kg-1 bodyweight) administration of tannic acid,

Freshly isolated blood from controls and from three members of a family with congenital bleeding tendency were examined with respect to ultrastructure of platelets. The fixation protocol, which included tannic acid, permitted the visualization of substructures in the marginal bundle. Whereas nearly

Acute tannic acid toxicity was studied in 6 adult Merino ewes by administering 7-10% (w/v) tannic acid solution once into the abomasum via an abomasal fistula at dose rates of 0.5, 1.0 or 2.0 g tannic acid/kg body weight. Samples of blood, urine and abomasal fluid were collected over a 48-h period

Massive blood loss and bacterial infection are major challenges for global public health. In this study, we developed tannic acid (TA)-loaded mesoporous silica (MS) nanoparticles for both hemorrhage control and effective antibacterium via covalent conjugation and electrostatic adsorption. The

The quorum sensing (QS) phenomenon regulates a myriad of pathogenic traits in the biofilm forming fish pathogen, Aeromonas hydrophila. Blocking the QS mechanism of A. hydrophila is a novel strategy to prevent disease in fish. This study evaluated the effect of tannic acid, a QS inhibitor, on A.

BACKGROUND Hemorrhage is a direct consequence of traumatic injury to the central nervous system and may cause innate immune reactions including cerebral Toll-like receptor (TLR) 4 upregulation which usually leads to poor outcome in the traumatic brain injury. In spinal cord injury (SCI), however,
