Exogenous corticosteroids (dexamethasone, cortisol) inhibit the adrenal secretion of corticosterone in the rabbit and decrease the concentration of corticosterone in aqueous humour, increase glycaemia and cause a rise in glucose concentration in the aqueous. Except for a slight rise 16 h after the corticosteroid administration no effect on plasma or aqueous content of total protein was observed...

The interaction of bacterial cells with surrounding environment depends on its surface characteristics such as hydrophobicity, hydrophilicity balance and net charge. In this paper, aqueous two-phase system partitioning of Escherichia coli strains based on their difference in surface properties is introduced in a microfluidic system. While aqueous two-phase system is widely use to separate biomo...

purpose: to evaluate the effect of early aqueous suppressants initiation on ahmed glaucoma valve success rate. methods: in this randomized clinical trial, a total of 94 eyes of 94 patients with refractory glaucoma were enrolled. the eyes were randomly selected into 2 groups. in group 1 (n=47), patients received early topical combination of timolol-dorzolamide twice daily after ahmed glaucoma va...

purpose: to evaluate the diagnosis of intraocular tuberculosis (tb) with polymerase chain reaction (pcr) and to report 13 cases of presumed intraocular tb. methods: of 168 patients with uveitis, 13 patients (7.74%) had criteria for intraocular tb (tb group). thirteen patients with non-tb uveitis were randomly selected as the control group. samples for pcr were obtained from the aqueous humor. s...

The juxtacanalicular connective tissue (JCT) is widely believed to generate the bulk of aqueous humor outflow resistance, while the pores of the inner wall endothelium are thought to generate at most 10% of this resistance in humans. However, the hydrodynamic interaction of these two components of the aqueous outflow system, which arises because of their spatial proximity, has only recently bee...

The aim of this study has been to determine whether eye chambers constitute part of the normal migratory pathway of naive CD4+ and CD8+ T cells in mouse and if natural CD4+CD25+Foxp3+ and CD8+CD25+Foxp3+ regulatory T cells are present within these eye compartments. To this aim, the cells obtained from aqueous humor (AH) of normal mice were phenotyped in terms of the expression CD4, CD8, CD25, C...

Both intraocular pressure and aqueous humour turnover rate were determined at intervals over three months in three females in order to investigate whether a correlation existed between these variables and the menstrual cycle. Not only was there a lack of correlation between intraocular pressure or aqueous humour flow rate and menses but intraocular pressure and aqueous humour flow rate were als...

helminths infections are chronic illness in human being and cattle. the use of alternate drugs has been a remedial measure against the resistant strains of helminth parasites, as well as means of reducing the cost of controlling diseases caused by helminthes. pseudocedrelakotschyi is a medicinally valuable plant and possesses various pharmacological properties. p. kotschyi has been traditionall...

Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...

OBJECTIVES We developed a population model that describes the ocular penetration and pharmacokinetics of penciclovir in human aqueous humour and plasma after oral administration of famciclovir. METHODS Fifty-three patients undergoing cataract surgery received a single oral dose of 500 mg of famciclovir prior to surgery. Concentrations of penciclovir in both plasma and aqueous humour were meas...
