This blinded study describes the effect of ibuprofen (IBU) on experimental pressure ulcers (PU) induced in the fuzzy rat model. Ibuprofen's fibrinolytic activity has been found effective in preserving dermal vasculature in rats following burn injury. Experimental pressure ulcers were generated on the hips of fuzzy rats with the aid of computer control,(More)
This study describes the sequential histopathological changes that occur in the development of pressure ulcers experimentally induced in the fuzzy rat model. Computer-controlled pressure was applied for six hours at a maximum of five sessions, to skin over the greater trochanter of anesthetized rats. Lesions were similar, but more pronounced after the(More)
Pressure ulcers continue to be a major health care problem. This paper describes an animal model and surface pressure delivery system for the production of experimentally derived pressure ulcers. A method for inducing dermal pressure lesions on the fuzzy rat was developed using a computer-controlled displacement column which produced a constant tissue(More)
Nao-Qing solution has been shown to be clinically effective in the treatment of acute ischemic stroke (AIS). The purpose of this study was to improve the pharmacokinetics and brain uptake of Nao-Qing, administered as an oil-in-water microemulsion. Sprague-Dawley (SD) rats were given Nao-Qing microemulsion by intranasal or intragastric routes. Samples of(More)
