We investigated the characteristics of delta9-tetrahydrocannabinol (THC)-induced impairment of learning and memory using an 8-arm radial maze task, a water maze, a visual discrimination task with 2 figures and a passive avoidance test in rats. THC (6 mg/kg, i.p.) impaired spatial memory in the standard task of the 8-arm radial maze. THC (4-6 mg/kg, i.p.)(More)
Disorders of intracellular Ca2+ homeostasis and intercellular coupling are thought to be crucial in the initiation and maintenance of malignant arrhythmias. The aim of this study was to investigate possible arrhythmogenic factors in spontaneously hypertensive rats (SHR) as well as their susceptibility to low K+-related arrhythmias. The experiments were(More)
Bilirubin is glucoronized by uridine diphosphate-glucuronosyl transferase 1A1 (UGT1A1) mainly in the liver, and excreted into bile. The conjugated form is metabolized into the unconjugated form, and then into urobilinogen by bacteria in the intestine. Unconjugated bilirubin and urobilinogen are absorbed into the blood stream. The kidney filtrates conjugated(More)
