The purpose of this work was to study the effectiveness of heparin plus cortisone, and of cortisone alone in control of corneal vascularization in rabbit eyes. Corneal vascularization was induced by de-epithelialization of the cornea and limbus and part of the bulbar conjunctiva with concurrent trephination and excision of a central 2-mm diameter corneal button. Inhibition of vascularization by...
Methods: Two different capsule formulations of these drugs were prepared. Formulation-I contains immediate release uncoated pellets of Rifampicin and Isoniazid. Formulation-IIcontains immediate release pellets of Rifampicin and enteric coated pellets of Isoniazid. These pellets were evaluated for various physicochemical parameters. Enteric coating was mainly done to prevent the release of Isoni...
Sustained release matrix pellets loaded with 5% w/w diclofenac sodium (DS) were prepared using extrusion/spheronization technique. Different polyethylene glycols (PEGs) of different molecular weight, namely PEG 2000, PEG 4000 and PEG 6000 were mixed with avicel PH 101® in different weight ratios to manufacture the pellet formulations and water was used as a binder. Mix torque rheomter was used ...
A multiparticulate chitosan-dispersed system (CDS), which is composed of the drug reservoir and the drug release-regulating layer, was developed for drug delivery. The drug release-regulating layer is a mixture of water-insoluble polymer and chitosan powder. The drug is released from CDS pellets in all regions of the gastrointestinal tract (from the stomach to the colon). CDS pellets containing...
Zeolite pellets containing 5 wt % of binder (methylcellulose or sodium metasilicate) were formed with a hydraulic press. This paper describes a mathematical model to predict the mechanical properties (uniaxial and diametric compression) of these pellets for arbitrary dimensions (height and diameter) using a design of experiments (DOE) methodology. A second-degree polynomial equation including i...
Two experiments were conducted to determine the dietary value of pellets containing kenaf (Hibiscus cannabinus cv. 'Everglade 41') hay. Averaged across both experiments, kenaf pellets contained 82.6% kenaf hay, 16.6% liquid molasses, and 0.8% mineral oil. The chemical composition of the kenaf pellet was 12.6% crude protein (CP), 41.2% neutral detergent fiber (NDF), and 14.4% acid detergent fibe...
Two experiments, using rats as subjects, investigated the effect of different reinforcer amounts and energy budgets on choice between constant and variable alternatives under a closed economy. Rats were housed in the chamber and were exposed to a modified concurrent-chains schedule in which the choice phase was separated from a rest phase during which the rats could engage in other activities. ...
Larvae of Culex pipiens and Cx. restuans in catch basins were exposed to Altosid pellets (4% active ingredient, [S]-methoprene) applied at a rate of 11.3 kg/ha (7 g of pellets per catch basin). Under field conditions, the pellets yielded an average 82% emergence inhibition of adult mosquitoes over the 15-wk trial period.
to understand the rate of oxidation of sponge irons and its mechanisim, their physical and chemical properties are normally required. in this report attempt has been made to show the results of research on varius pellets and briqutts produced at ahwaz steel complex. in presenting these data, the rate of oxidation of these articles in air between 300 and 600 °c is also quotted and analysed. in a...
This paper describes a study of behavioural response in terrestrial isopod Oniscus asellus when offered two food pellets of different quality. One group had a choice of sterilised food and food pellets covered with mould. The other group had a choice of uncontaminated and cadmium-dosed food. During the behavioural test, the animals were monitored by a video camera and each visit to food pellets...
