Ribeiro,Alexandre Pinto; Escobar,André; Motheo,Tathiana Fergunson; Godoy,Guilherme Selera; Laus,José Luiz.
Efficacy of meloxicam, administered by different routes was studied in experimental uveitis in dogs. Anterior chamber paracenteses was accomplished at two different moments (M0 and M1), with a five hour interval among them. At M0 and M1, 0.2mL of aqueous humor was collected and total protein and prostaglandin E2 (PGE2) quantitation was determined. Four groups were formed (n=5), which received meloxicam at the end of M0. by the following routes: subcutaneous (GIm), subconjunctival (GII), and topical (GIII). A fourth group that received no treatment was instituted (Control). Conjunctival histopathology of the GII was performed. Results were evaluated statistically (P≤0.05). In all groups, protein and PGE2 values enhanced significantly in M1. Protein and PGE2...

Qualitative and quantitative tear film abnormalities in dogs Ciência Rural
Ribeiro,Alexandre Pinto; Brito,Fabio Luiz da Cunha; Martins,Bianca da Costa; Mamede,Fabrício; Laus,José Luiz.
Tear film disorders in dogs can be classified into quantitative or qualitative abnormalities, or both, and are commonly observed in daily clinical practice. Inadequate production of one or more tear film components can lead to variable degrees of ocular disorders, called keratoconjunctivitis sicca. Keratoconjunctivitis sicca in dogs has several causes, but in most cases the disease is idiopathic, with T lymphocytes playing a role. In veterinary medicine, the diagnosis is made based on the results of the Schirmer tear test. In this article, we review aspects related to the etiopathogenesis and diagnosis of keratoconjunctivitis sicca in dogs and discuss new therapeutic modalities for this disease.
