The pathogenesis of gastric antral hemorrhage and ulceration is unclear. This paper first proposes that antral hemorrhagic ulcers produced in rats are associated with attenuation of defensive parameters (such as mucosal glutathione levels and histamine release, as well as aggravation of aggressive
The pathogenic mechanisms underlying betel quid chewing (BQC)-induced gastric haemorrhagic ulcer are totally unknown. This study first demonstrated that BQC produced gastric haemorrhagic ulcer via oxidative stress that could be protected by lysozyme chloride and glutathione in rats. Male Wistar rats
OBJECTIVE
To evaluate the protective effect of lysozyme chloride on betel quid chewing (BQC) aggravated gastric oxidative stress and hemorrhagic ulcer in rats with diabetes mellitus (DM).
METHODS
Male Wistar rats were challenged intravenously with streptozotocin (65 mg/kg) to induce DM. Rats were
The role of erythrocytes in realization of interrelation of the immunomodulating effects of lysozyme and naphthoquinones in normal and under conditions of acute hemorrhage was studied. Interaction of lysozyme and menadione at the level of intact erythrocytes and their stroma resulted in formation of
A study was made of the dynamics of the lysozyme activity of the serum in dogs which sustained clinical death on the background of a 2-hour hypovolemic hypotension due to blood loss. There was revealed a progressive increase in the lysozyme activity of the serum during the hypotension and during the
Acute hemorrhage leads to a decrease in the phagocyte number and index, the NBT test parameters, and the NADPH oxidase activity and to an increase in the Ca2+ ATPase activity in polymorphonuclear leukocytes on the peripheral blood. Lysozyme produces effective correction of the above parameters of
BACKGROUND
Calcium and cholesterol play major roles in the formation of atherosclerosis. Whether severe atherosclerosis induced by co-administration of a mixture containing vitamin D2 (vit D2) and cholesterol can result in gastric hemorrhagic damage is unknown. Gastric oxidative stress and
Lysozyme is well known as a natural antimicrobial agent, but its function is limited in that it only combats Gram-positive bacteria. We investigated the inhibitory effects of dextran-conjugated lysozymes (DLs) against some strains of Gram-negative bacteria and viral hemorrhagic septicemia virus
Lysozyme injections (1 or 5 mg/kg) produced marked immunomodulating, antioxidant and hepatoprotective effects in Wistar rats which had lost much blood (3% body mass). Lysozyme action is mediated by heavy erythrocytes and glass-adherent splenocytic cytokines the production of which is provoked by
OBJECTIVE
Our recent studies proved that menstrual discharge is exceptionally rich in bactericidal hemoglobin peptides (hemocidins). Of special interest is the behavior of hemocidins in low pH of the vagina, in different ionic strengths, and in the presence of other specialized antibacterial
We report here on a case of intracranial inflammatory pseudotumor arising from the trigeminal nerve. A 52-year-old man presented with sudden onset severe headache. He had had facial numbness several months earlier and no signs indicating infection. On the computerized tomography scan, intracranial
