HPLC/electrochemical detection was used to identify five major low MW water soluble electrochemically active molecules from the aqueous humor of three species of mammals: New Zealand White rabbits and humans (diurnal) and Sprague-Dawley rats (nocturnal). These molecules are L-cysteine (CYS), L-ascorbic acid (AA), glutathione (GSH), uric acid (UA) and L-tyrosine (TYR); all of these molecules hav...

INTRODUCTION We aimed to investigate activities of metalloproteinases 2 (MMP-2) and MMP-9 in aqueous humour of patients with diabetes mellitus with various stages of diabetic retinopathy. MATERIAL AND METHODS We included 36 samples of aqueous humour of patients suffering from diabetes mellitus, undergoing routine cataract surgery. Seven of them suffered from proliferative diabetic retinopathy...

Adult rabbits were given single intravenous injections of 25 mg. per kilogram of sodium dicloxacillin. At intervals of time ranging from 15 minutes to 8 hours after injection, primary or secondary aqueous humor was aspirated from each eye. At the same time, a specimen of cardiac blood was withdraion. Other animals were given subconfunctival injections of 50 mg. of dicloxacillin. Aqueous humor w...

The penetration into the eye and the systemic absorption of 2% cyclosporin eye drops were determined by polarisation immunofluorescent assay of cyclosporin in the aqueous humour and plasma of 30 patients at the time of cataract surgery. The results were then compared with the corresponding results after oral administration at a dosage of 5 mg/kg/day to three further patients. The maximum intrao...

this paper deals with application of polyaniline coated on wood sawdust for removal ofmethylene blue (mb) dye from aqueous solutions. polyaniline coated onto sawdust (termedas pan/sd) was prepared via direct chemical polymerization onto sawdust which waspreviously soaked in the monomer (aniline) solution in acidic (hc1) media. adsorptionexperiments were carried out using batch system. the effec...

We determined the clinical potential of cefazolin by assaying aqueous samples for levels of aqueous penetration of cefazolin in humans and rabbits after subconjunctival injection. Cefazolin is a broad spectrum antiotic that appears to penetrate aqueous humor in bactericidal concentrations after subconjunctival injection and may serve as a useful alternative in patients sensitive to other antibi...

The coefficient of plasma protein entry into the aqueous humor, kin, was calculated in the human eyes from the aqueous protein concentration measured with a flare-cell meter and from the aqueous flow rate determined with fluorophotometry. The value of kin averaged 3.47 +/- 0.25 x 10(-5) min-1 (mean +/- SEM) in 12 eyes of six normal young volunteers. The time course of changes in aqueous protein...

LDH activity was determined in aqueous humour samples from 11 eyes (of 10 children), four of which contained retinoblastoma. Simultaneous serum LDH levels were also determined in eight of the children. There was no correlation between serum and aqueous humour LDH activity. Total aqueous humour LDH activity ranged from 0 to 99 i.u/l. in the seven eyes with non-neoplastic conditions. It was 56, 1...

BACKGROUND The aim of the paper is to present the Polish adaptation of the Humor Climate Questionnaire (HCQ), designed to measure humor as organizational climate feature. MATERIAL AND METHODS The authors employed back-translation and independent judges method to choose the best version of the translated items. The psychometric properties of HCQ were estimated on the basis of 2 samples: the ba...

The experimental research that looks into the effects of political humor on an individual's attitudes toward politics and politicians does not evaluate its long-term effects. With this in mind, this study aims to determine the possible effects that being exposed to humor which belittles politicians may have on an ordinary citizen's trust in them, while at the same time it observes the possible ...
