ABH: angina bullosa hemorrhagica H&E: hematoxylin-eosin INTRODUCTION Angina bullosa hemorrhagica (ABH) is a rare benign disorder characterized by sudden onset of painless, blood-filled, blisters of the oral cavity that quickly expand and rupture spontaneously within 24 to 48 hours. First reported in 1967, ABH has been noted under other diagnostic terms including recurrent or traumatic oral hemo...

Angina bullosa hemorrhagica (ABH) is an oral mucosal blood blister that develops without blood dyscrasia or vesiculobullous disorder. Although a minor mucosal trauma has been suggested as a triggering factor for ABH, its etiopathogenesis, especially the causative role of systemic conditions, is largely unknown. We investigated the presence or absence of local factors as well as systemic backgro...

Angina bullosa hemorrhagica (ABH) is a benign disorder of the oral cavity. Clinically, oral, blood-filled blisters are seen. To give a proper diagnosis, one should rule out any other cause. We aim to present this case in order to emphasize this rare cause of oral bullae which is necessary to be differentiated from many serious dermatological and hematological disorders.

We examined the effects of hemicellulase-treated Agaricus blazei (AB fraction H, ABH) on growth of several tumor cell lines. ABH inhibited the proliferation of some cell lines without cytotoxic effects. It markedly prolonged the S phase of the cell cycle. ABH also induced mitochondria-mediated apoptosis in different cell lines. However, it had no impact on the growth of other cell lines. ABH in...

The Bacillus subtilis abh gene encodes a protein whose N-terminal domain has 74% identity to the DNA-binding domain of the global regulatory protein AbrB. Strains with a mutation in abh showed alterations in the production of antimicrobial compounds directed against some other Bacillus species and gram-positive microbes. Relative to its wild-type parental strain, the abh mutant was found defici...

An experimental demonstration of the broadband passive damping capacity a vibro-impact acoustic black hole (VI-ABH) is reported. A VI-ABH an adaptation classical ABH design consisting beam with tapered edge decreasing thickness creating (ABH), complemented by contact points on which impacts during its vibration. The nonlinearity creates rapid and efficient transfer vibrational energy from low-f...

Platelets express ABH antigens, which can adversely effect platelet transfusion recovery and survival in ABH-incompatible recipients. To date, there has been no large, comprehensive study comparing specific donor factors with ABH expression on platelet membranes and glycoconjugates. We studied ABH expression in 166 group A apheresis platelet donors by flow cytometry, Western blotting, and thin ...
