Ceftriaxone's toxic effects were assessed in albino rabbits after intravitreal injection. Doses up to 5 mg did not alter the B-wave amplitude. Following 7.5-and 20-mg doses, B-wave amplitude ratios were depressed at 24 hours and normal at seven and 14 days. A 50-mg dose caused a temporarily flat B-wave 24 hours after injection. At two weeks this ratio(More)
The effects of 4% epinephrine bitartrate and 0.5% timolol on ocular and optic nerve blood flow were studied in phakic and aphakic rabbit eyes using a radioactive microsphere (85Sr) technique. Either epinephrine or timolol was given topically as eight drops in the hour immediately preceding blood flow measurements (one drop every 7.5 minutes). Epinephrine(More)
Blood flow was measured in several tissues of the rabbit eye following intravitreal injection of a dose of endotoxin that induces an inflammatory response. In separate experiments, the vascular permeability of the inflamed eye was estimated by iris fluorescein angiography and by measuring protein influx into the aqueous humor. The effect of topical(More)
A reproducible animal model is necessary to examine the use of antimicrobial agents for prophylaxis and treatment of bacterial endophthalmitis. We determined the minimum inoculum size of S. aureus and P. aeruginosa that consistently produced endophthalmitis when injected into aphakic rabbit eyes immediately following surgery. Both anterior chamber and(More)
— This paper presents the simulation of Worldwide Interoperability for Microwave Access (WiMAX) system based on Orthogonal Frequency Division Multiplexing (OFDM) with different adaptive modulation techniques. WiMAX is the next generation broadband wireless technology which offers greater range and bandwidth compared to the other available broadband wireless(More)
The effect of digital massage on intraocular pressure and ocular and optic nerve blood flow was studied in anaesthetized rabbits. Digital massage was performed for 15 min, with pressure release for 15 seconds after each 45 seconds of massage. Blood flow was measured in the iris, ciliary processes, choroid, retina, and optic nerve using (85Sr)-labelled(More)
The Honan Intraocular Pressure Reducer (HIPR) was applied to rabbit eyes for 30 min at pressure settings of 0, 30, 50, or 100 mmHg. Ocular blood flow was measured using (85Sr) radioactively labelled 15 micron microspheres either with the HIPR applied to the eye or 15 min after removal. Intraocular pressure was measured before applying the HIPR, immediately(More)
The enthusiastic clinical reports on normothermic blood cardioplegia contrast with the paucity of data on the myocardial metabolic effects of this technique. The present study was therefore designed to assess whether normothermic blood cardioplegia really provides an aerobic environment during aortic cross-clamping. Thirty-one patients undergoing coronary(More)
The design FSS structure consists of FSS structures placed on the FR4 and glass. The square loop FSS is designed and simulated using the CST Microwave Studio software at 2.4 GHz based on industrial, scientific and medical bands (ISM) standard. The reflection (S11) and transmission (S21) of the design FSS structure is analyzed based on the six types of(More)
The effect of oral and intravenous pentoxifylline administration on ocular and optic nerve blood flow was studied in phakic rabbit eyes using a radioactive microsphere (85Sr) technique. Blood flow measurements were performed either 30 min after intravenous injection of 20 mg of pentoxifylline, or 2-3 h after oral administration of 20 mg of pentoxifylline.(More)
