Infection of vascular prosthesis in aortofemoral area.

Objectives: To determine the frequency of vascular prosthesis infection in aortofemoral area and to demonstrate their course, treatment and risk factors.

Methods: The file was formed by patients who had been operated on because of infection of vascular reconstruction in aortofemoral area at IInd department of surgery of the St. Anne's Faculty Hospital in Brno in the 2000-2004 period.

The effect of delta-9-tetrahydrocannabinol (delta-9-THC) on the release of nonesterified fatty acids in various brain structures.

There was studied the effect of repeated administration of delta-9-THC (10 mg/kg per os for two days) on the level of nonesterified fatty acids (NEFA) in the brain structures of laboratory rats. Palmitic acid, stearic acid, oleic acid and arachidonic acid were estimated with the help of gas chromatography after preliminary separation by TLC. After administration of delta-9-THC, the levels of NEFA decreased in the brain cortex, the brain stem and most in the hypothalamus.
