Aqueous humor turnover in the cat eye determined by intracameral injection of inulin*C was found to be 2.1 per cent per minute, a value which is in close agreement with that reported for other species. The inhibition of aqueous humor formation induced by acetazolamide was dose dependent bid the quantities required were much higher than those reported necessary to lower the eye pressure. The dat...

BACKGROUND The study was aimed to evaluate the anti-inflammatory activity of ethanolic and aqueous extracts of Polygonum minus (Huds) using in vitro and in vivo approaches. METHODS The in vitro tests used to evaluate ethanolic extract are cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), lipooxygenase (5-LOX), secretory phospholipase-A2 (sPLA2) inhibition assay whilst the in-vivo effect was...

PURPOSE To determine the effects of the kappa opioid agonist, bremazocine (BRE), on intraocular pressure (IOP) and aqueous humor dynamics in normotensive cynomolgus monkeys. METHODS IOP, pupil diameter, refraction, aqueous humor flow, and mean arterial pressure (MAP) were measured following unilateral topical application of 1 to 100 microg BRE. IOP and MAP responses to 100 microg BRE were rep...

Previously we have reported a family of convective patterns formed by charge-stabilized aqueous colloidal suspensions under constant (dc) vertical electric fields [Y. Han and D. G. Grier, J. Chem. Phys. 122, 164701 (2005); and ibid. 125, 144707 (2006)]. These patterns form in the bulk when electrokinetic forces act in the opposite direction to gravity. Here, we report on cellular patterns that ...

Objective This study was initiated to investigate the effect of Portulaca oleraceae on morphine dependence in mice. Materials and Methods Dependence was induced using the subcutaneous injections of morphine for 3 days. On the day 4, morphine injected 2 h prior to intraperitoneal injection of naloxone. The plant extracts ethanolic or aqueous administered 0.5 h before the final dose of morphine. ...

conclusions results from the present study elucidated that treatment with the aqueous extract of l. citriodora leaves was well tolerated via daily ip injection at doses up to 200 mg/kg for a period of 21 days and did not produce any toxicity. the safety of l. citriodora aqueous extract was also confirmed by cell viability assay. objectives the present study evaluated the acute, subacute, and ce...

AUREO0MYCIN has now become established as an important and powerful antibiotic and has proved itself effective in several ophthalmological infections which failed to respond to other treatment. A preliminary' report has already been made from this clinic on the use of this drug in ophthalmology (Duke-Elder and others, 1950). The present communication describes our further experiences with this ...

PURPOSE To report crystal formation as a complication of intravitreal ganciclovir injection. PATIENTS AND METHODS A 73-year-old female patient with unilateral cytomegalovirus retinitis was treated with intravitreous ganciclovir (4 mg/0.04 mL). RESULTS After the intravitreal injection, sudden crystallization was observed in the vitreous humor. The patient experienced marked reduction in visu...

The ratio of concentration of chloride in the aqueous humor compared with that in the plasma of rabbits, dogs, and human beings, was determined by the Schales and Sendroy methods. Consistent results were obtained in all the experiments by the Schales method with or without protein, and by the Sendroy method without protein. In the presence of protein, however, lower chloride concentrations were...

Ceftriaxone penetrates into the aqueous humour in man. The interaction of indomethacin on the disposition of ceftriaxone appeared to be time-dependent. Indomethacin delayed ceftriaxone penetration into, but enhanced its persistence in, the aqueous humour, permitting a period of antibioprophylaxis covering the required time for surgical treatment.
