PURPOSE These experiments were designed to study the effect of cytokines and nitric oxide (NO) on rat retinal pigment epithelial (RPE) cell tight junctions in vitro. METHODS Cultures of confluent RPE cells from retinas of PVG rats (a strain susceptible to development of experimental uveitis) were prepared on filters and incubated with various stimulants.(More)
Footpad injection of lipopolysaccharide (LPS) from Salmonella typhimurium in Lewis rats induces an acute anterior and posterior endotoxin-induced uveitis (EIU). To investigate the role of macrophages in the pathogenesis of EIU, we eliminated macrophages by means of liposomes containing dichloromethylene-diphosphonate (Cl2MDP), a drug which depletes(More)
In this paper, we will consider an hp-finite elements discretization of a highly indefinite Helmholtz problem by some dG formulation which is based on the ultra-weak variational formulation by Cessenat and Deprés. We will introduce an a posteriori error estimator and derive reliability and efficiency estimates which are explicit with respect to the(More)
Pm: A new hydrogel composed ofiota-carrageenan/polyvinylpyrrolidon (i-cgn/pvp) was tested in rabbit eyes to dctennine its intraocular tolerance and to evaluate its suitability as a vitreous substitute. MefhodF: Aver pars-plana lensectomy and pars-plana vitrectomy 1,Sml of i-cgn/pvp were injected into 4 eyes of 4 rabbitsThe untreated contralateral eyd served(More)
