OBJECTIVE
Inflammation plays a critical role in secondary brain damage after intracerebral hemorrhage (ICH). However, the mechanisms of inflammatory injury following ICH are still unclear, particularly the involvement of NLRP3 inflammasome, which are crucial to sterile inflammatory responses. In
Brain cell death after intracerebral hemorrhage may be mediated in part by an apoptotic mechanism. Colostrum is the first milk produced by mammals for their young. It plays an important role in protection and development by providing various antibodies, growth factors and nutrients, and has been
Dengue virus infection causes life-threatening hemorrhagic fever. Increasing evidence implies that dengue viral nonstructural protein 1 (NS1) exhibits a tendency to elicit potentially hazardous autoantibodies, which show a wide spectrum of specificity against extracellular matrix and platelet
OBJECTIVE
To observe the effect of Dahuang Zhechong Pill (DZP) on the content of amino acids in hippocampal tissue of model rats of ischemic cerebral hemorrhage (ICH).
METHODS
Collagenase and heparin were injected into caudate nucleus to establish ICH rat model. The content of glutamic acid (Glu),
N-Methyl-D-aspartic acid (NMDA) (10 pmol in 100 nl of 0.9% sodium chloride solution) was microinjected into the nucleus tractus solitarii (NTS) of urethane-anesthetized, paralyzed and artificially ventilated rats, and cerebral blood flow (CBF) was determined using a combination of labeled
Agmatine (CAS 2482-00-0), an amine formed by decarboxylation of L-arginine, interacts with several targets like alpha2-adrenergic, imidazoline and N-methyl-D-aspartic acid (NMDA) receptors and besides it is involved in the nitric oxide mediated effects. It has also been proposed that it possesses
Membrane glycoprotein alpha IIb beta 3 on platelets plays a pivotal role in hemostasis by mediating RGD-(arginine-glycine-aspartic acid)-dependent platelet adhesion and aggregation. Antagonists of alpha IIb beta 3 ligand binding function, such as antibodies, snake venom peptides, or synthetic
8-Guanidino-octanoyl-aspartic acid-phenylalanine (SC-49992), a mimetic of the tetrapeptide arginine-glycine-aspartic acid-phenylalanine, is a potent inhibitor of platelet aggregation. In this study, the authors examined the effects of SC-49992 on the time to lysis of thrombi and the time to
Synthetic vascular prostheses lack the uniquely low thrombogenicity provided by the endothelial cell lining of autogenous saphenous vein or artery grafts. The thrombogenic nature of the synthetic graft surface becomes a major determinant of early prosthetic graft patency. We demonstrate in a baboon
Hemostats, which are used for immediate intervention during internal hemorrhage in order to reduce resulting mortality and morbidity, are relatively rare. Here, we describe novel intravenous nanoparticles (CPG-NPs-2000) with chitosan succinate (CSS) as cores, polyethylene glycol (PEG-2000) as
Cerebrospinal fluid (CSF) amino acid levels including excitatory amino acids (i.e. glutamate and aspartate) in 25 preterm and 18 full-term newborn infants with no serious disease except intracranial hemorrhage (ICH) were measured. ICH was detected in 13 preterm and six full-term infants on the basis
BACKGROUND
The authors are aware of only one article investigating amino acid concentrations in cerebrospinal fluid (CSF) in patients with ruptured intracranial aneurysms, and this was published 31 years ago. Since then, both management of subarachnoid haemorrhage (SAH) and amino acid assay
N-(Phosphonacetyl)-L-aspartic acid (PALA) was given as a 5-day continuous infusion in a phase I trial. Dose-limiting toxic effects noted were diarrhea occurring at doses of greater than or equal to 6 g/m2/course, mucositis occurring at doses of greater than or equal to 7.5 g/m2/course, and skin rash
A platelet aggregation inhibitory protein, bitistatin, was isolated from the venom of the puff adder Bitis arietans. This protein is a single-chain peptide containing 83 amino acids and 7 disulfide bonds. Bitistatin contains the sequence arginine-glycine-aspartic acid and shows considerable homology
