Background. Salidroside is a biologically active compound derived from Rhodiola rosea L. Studies showed that salidroside after i.v. injection is extensively metabolized to p-tyrosol and only trace amounts of salidroside are found in the brain tissue.Objective. The aim of the study was to investigate the neuroprotective effects of p-tyrosol in the global cerebral ischemia-reperfusion (GCI) model.Study design. A total of 103 Wistar rats were assigned to groups of sham-operated (n = 10), control (n = 42), p-tyrosol-treated (n = 36), and pentoxifylline-treated (n = 15) animals. The rats of control, p-tyrosol-treated, and pentoxifylline-treated groups received intravenously 0.9% NaCl solution, 2% solution of p-tyrosol in doses of 5 mg/kg, 10 mg/kg, and 20 mg/kg, and pentoxifylline in a dose of 100 mg/kg, respectively, daily for 5 days. Rats were examined at days 1, 3, and 5 after GCI. After evaluation of neurological deficit, animals were euthanized for morphological and biochemical characterization.
