title: Prophylactic effects of ajoene on cerebral injury in stroke-prone spontaneously hypertensive rats (SHRSP).
abstract: As part of a basic study on the prevention of cerebral injury, ajoene (0.5 mg/d) and oil-macerated garlic extract (OMGE, containing 0.5 mg ajoene/d) were administrated to stroke-prone spontaneously hypertensive rats (SHRSP) among 8 weeks from 9 weeks of age. In the control group, 3 of 10 rats died (30%), whereas all SHRSP treated by ajoene or OMGE survived. Our results suggested that ajoene and OMGE-treatment reduced the mortality and cerebral injury in SHRSP. The levels of thiobarbituric acid reactive substance (TBARS) and the enzymatic activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) in the serum of stroke stage of SHRSP were measured. The results obtained were as follows; the TBARS level of the ajoene and OMGE-treated groups were lower than those of control groups. On the other hand, the GSH-Px and SOD activities of the ajoene and OMGE-treated groups were higher. Our results suggested that ajoene and OMGE were capable of having prophylactic effects on cerebral injury in SHRSP.
