Aerobic metabolism on muscle contraction in porcine iris sphincter.

Musashino/Tokio – mechentel news – Eyes are supplied O2 through the cornea and vessels of the retina and iris, which are tissues characterized by aerobic metabolism. Meanwhile, there are no reports on the association between iris sphincter contraction and aerobic metabolism. In this paper, we studied the aforementioned association. Eyes from adult pigs of either sex were obtained from a local abattoir. A muscle strip was connected to a transducer to isometrically record the tension. O2 consumption...

Ocular Penetration and Pharmacokinetics of Ripasudil Following Topical Administration to Rabbits.

Higashimurayama/Tokio – mechentel news – We evaluated the ocular pharmacokinetics of ripasudil (K-115), a selective Rho-associated coiled-coil containing protein kinase (ROCK) inhibitor, following topical administration to rabbits. We determined the ocular distribution of [(14)C]ripasudil by whole-head autoradiography and the radioactivity of each ocular tissue after single and multiple instillation of [(14)C]ripasudil to pigmented rabbits. We also measured the aqueous humor concentrations after...

Efficacy of moxidectin 2.5% and imidacloprid 10% in the treatment of ocular thelaziosis by Thelazia callipaedain naturally infected dogs.

Valenzano/Leverkusen – mechentel news – Thelazia callipaeda (Spirurida, Thelaziidae) has been documented as agent of ocular infection in domestic animals (dogs and cats), wildlife (e.g., foxes, hares, rabbits), and humans. In the last two decades, this parasitosis has been increasingly reported in several European countries. Both adult and larval stages of the eyeworm are responsible for symptoms ranging from mild (e.g., lacrimation, ocular discharge, epiphora) to severe (e.g., conjunctivitis,...

Immunological and pathological investigations in equine experimental uveitis.

Eysines – mechentel news – The pathogenic mechanism of equine recurrent uveitis (ERU) is still poorly defined and many variations between experimentalanimal models and spontaneous disease exist. The aim of our study was to investigate if Th17 cell-mediated response plays role in the pathogenesis of the used experimentalmodel in horses and to reveal its pathological findings. Experimental uveitis was induced in 6 healthy horses. The concentrations of retinal autoantigen CRALBP and IL-17...
