This study examined neuroprotective effect of silymarin (SM) in a model of Parkinson's disease (PD). Unilateral intrastriatal 6-hydroxydopamine (6-OHDA)-lesioned rats were pretreated i.p. with SM (100 and 200 mg/kg) 1 h before neurotoxin injection. Fulvestrant was used to evaluate the involvement of estrogen receptors. Net apomorphine-induced rotations and(More)
A large body of experimental evidence supports a role for oxidative stress as a mediator of nerve cell death in Parkinson's disease (PD). Phytoestrogens such as genistein have been reported to prevent neuronal degeneration caused by increased oxidative burden, therefore, this study examined whether genistein administration at a high dose would attenuate(More)
Parkinson's disease (PD) is a neuropathological and debilitating disorder involving the degeneration of mesencephalic dopaminergic neurons. Neuroprotective effect of pelargonidin (Pel) has already been reported, therefore, this study examined whether Pel administration would attenuate behavioural and structural abnormalities and markers of oxidative stress(More)
Due to the anti-diabetic and antioxidant activity of green tea epigallocatechin-gallate (EGCG), this research study was conducted to evaluate, for the first time, the efficacy of chronic treatment of EGCG on alleviation of hyperalgesia in streptozotocin-diabetic (STZ-diabetic) rats. Male Wistar rats were divided into control, diabetic, EGCG-treated-control(More)
Diabetes mellitus (DM) is associated with learning, memory, and cognitive deficits. S-allyl cysteine (SAC) is the main organosulfur bioactive molecule in aged garlic extract with anti-diabetic, antioxidant, anti-inflammatory and nootropic property. This research was conducted to evaluate the efficacy of SAC on alleviation of learning and memory deficits in(More)
Due to anti-diabetic and antioxidant activity of green tea epigallocatechin gallate (EGCG) and the existence of evidence for its beneficial effect on cognition and memory, this research study was conducted to evaluate, for the first time, the efficacy of chronic EGCG on alleviation of learning and memory deficits in streptozotocin (STZ)-diabetic rats. Male(More)
Although drug-induced rotational behavior has conventionally been used for the assessment of functional asymmetry in 6-hydroxydopamine (OHDA)-lesioned rats, a pure behavioral test that can evaluate animals with dose-dependent lesions of the dopaminergic nigrostriatal system in a drug-free state may better reflect a more natural response following lesion. In(More)
In this study, some underlying mechanisms responsible for the beneficial effect of chronic oral administration of resveratrol on aortic reactivity of streptozotocin (STZ)-diabetic rats were investigated. Male diabetic rats received resveratrol (10 mg/kg/day) for 8 weeks, 1 week after diabetes induction. Treatment of diabetic rats with resveratrol produced a(More)
Intracerebroventricular (ICV) injection of streptozotocin (STZ) causes cognitive impairment in rats. The beneficial effect of naringenin (NAR) was investigated on ICV STZ-induced learning, memory, and cognitive impairment in male rats. For this purpose, rats were injected with ICV STZ bilaterally, on days 1 and 3 (3 mg/kg). The STZ-injected rats received(More)
In the present study, the effect of aqueous garlic extract (Allium sativum; 100 mg/Kg/day; i.p.) on the vascular reactivity of streptozotocin (STZ)-diabetic rats was investigated. Vascular reactivity of isolated aortic rings was assessed by measuring phenylephrine-induced contractile and acetylcholine-induced relaxation responses. The results showed that(More)
