Effect of ophthalmic preparation of methyldopa on induced ocular hypertension in rabbits.

Glaucoma is a type of ocular disorder with multifaceted etiologies characterized by progressive optic nerve damage and ultimately loss of visual field. This study aimed to evaluate the possible intraocular pressure (IOP) lowering effect of an ophthalmic preparation of methyldopa (MD) in corticosteroid-induced ocular hypertension in rabbits. Forty New Zealand white male rabbits were assigned to the experiment and then randomly divided into five groups (n = 8).

Lipopolysaccharide from Rhodobacter spheroids modulate toll-like receptors expression and tissue damage in an animal model of bilateral renal ischemic reperfusion injury.

Ischemic reperfusion injury (IRI) of the kidneys is a direct sequela of surgical procedures associated with the interruption of blood supply. The pathophysiology of IRI is complicated, and several inflammatories, apoptosis, and oxidative stress pathways are implicated. Among the major receptors directly involved in renal IRI are the toll-like receptors (TLRs), specifically TLR2 and TLR4.
