Forty-five relatives of 4 families with hereditary angioneurotic edema (HANE) were studied. Twenty-five, including 11 asymptomatic kindreds with the disposition, showed typical changes in complement system compatible with HANE. Follow-up study of HANE patients showed that, even in remission period,
OBJECTIVE
To describe a patient with acquired immunodeficiency syndrome (AIDS) who presented with cystoid macular edema (CME) which was not associated with active cytomegalovirus (CMV) retinitis or AIDS-related microvasculopathy.
METHODS
A 32-year-old man with AIDS and a past ocular history of
Hypothermia is an effective neuroprotective treatment for brain injury caused by intracerebral hemorrhage (ICH). It is reported to reduce brain edema and neuronal cell death. Thrombin, a coagulation protease released from blood clots, is critical in brain edema formation following ICH. Protease
Brain edema is one of the most frequent and serious complications of intracerebral hemorrhage (ICH), but how the ICH cause brain edema is unknown. Our studies were designed to investigate the regulation and distribution of protease nexin-1 (PN-1), thrombin and aquaporin-4 (AQP-4) in brain edema
Our previous studies have demonstrated that thrombin plays an important role in intracerebral hemorrhage (ICH)-induced brain injury and edema formation. We, therefore, examined whether nafamostat mesilate (FUT), a serine protease inhibitor, can reduce ICH-induced brain injury. Anesthetized male
OBJECTIVE
Our previous studies showed that thrombin contributes to brain edema in gliomas. The present study investigated the role of a thrombin receptor, protease activated receptor-1 (PAR-1), in edema formation in glioma models.
METHODS
These experiments were performed in Fischer 344 rats, PAR-1
Acute lung injury (ALI) is characterized by neutrophil infiltration and the release of proteases, mainly elastase (NE), cathepsin G (Cat G) and proteinase 3 (PR3), which can be controlled by specific endogenous inhibitors. However, inhibitors of these proteases have been isolated from different
Aim: To investigate the changes of water content in brain tissue, the expression of AQP4mRNA after cerebral hemorrhage in rats, and the intervention effect of Protease activated receptor 1 inhibitor (PAR1 inhibitor) on both.
Snake venom serine proteases (SVSPs) represent an essential group of enzymatic toxins involved in several pathophysiological effects on blood homeostasis. Some findings suggest the involvement of this class of enzymatic toxins in inflammation. In this paper, we purified and isolated a new gyroxin
FUT-175 inhibited the zymosan-induced rat paw edema in a dose-dependent manner, while indomethacin exhibited no significant activities in this model. FUT-175 also inhibited the decrease in hemolytic complement (CH50) induced by zymosan in vitro, and indomethacin was inactive. These results suggest
Mouse mast cell protease 11 (mMCP-11) is the most recently identified member of the mouse mast cell tryptase family. This tryptase is preferentially produced by basophils in contrast to other members that are expressed by mast cells but not basophils. Although blood-circulating basophils have long
BACKGROUND
Hereditary angioneurotic edema (HANE) is an autosomal dominant disease due to genetic alterations at the C1 inhibitor gene. Mutations within the C1 inhibitor gene are responsible for the molecular defect in type II HANE. Most of the dysfunctional proteins result from mutations involving
