Muscle Toxicity of Diatrizoate and Iohexol in Rabbits

Comparative trial of iohexol 350, a non-ionic contrast medium, with diatrizoate (Urografin 370) in left ventriculography and coronary arteriography.

In a prospective double blind randomised study in 25 consecutive patients a conventional ionic contrast medium (Urografin 370) was compared with the new non-ionic medium iohexol 350 ( Omnipaque ) in left ventriculography and coronary arteriography. In left ventriculography there was a clear patient preference for iohexol by both a visual analogue scale and independent observer assessment. Iohex...

Effects of Nigella sativa oil and ascorbic acid against oxytetracycline-induced hepato-renal toxicity in rabbits

Objective(s):  Oxytetracycline (OTC) is a broad spectrum antibiotic widely used for treatment of a wide range of infections. However, its improper human and animal use leads to toxic effects, including hepatonephrotoxicity. Our objective was to evaluate protective effects of Nigella sativa oil (NSO) and/or ascorbic acid (AA), against OTC-induced hepatonephrotoxicity in rabbits. Materials and Me...

synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...

Absorption after subarachnoid and subdural administration of iohexol, 51Cr-EDTA, and 125I-albumin to rabbits.

The absorption of the nonionic contrast medium iohexol, the clearance tracer 51Cr-ethylenediaminetetraacetic acid, and the blood-pool marker 125I-human serum albumin was studied after subarachnoid and subdural injection in rabbits. Subdural deposition of the contrast medium and 51Cr-ethylenediaminetetraacetic acid resulted in a faster absorption rate and higher achieved blood levels than a suba...
