Parkinson disease is characterized by the death of dopaminergic neurons in the substantia nigra pars compacta. We explored the neuroprotective effect of Selegiline and Piribedil, the Monoamine Oxidase Type B (MAO-B) and dopamine agonist to Parkinson disease (PD). After embryonic Wistar rat were induced by cerebrospinal fluid (CSF) from PD patients, Selegiline and Piribedil were administered to ...

The incidence and range of spontaneous central nervous system tumors were determined in control Charles River rodents (Sprague-Dawley, Han-Wistar, Wistar rats, and CD-1 mice) from regulatory carcinogenicity studies carried out over the period 2002 to 2013 and were compared with the previously published data. In both species, the brain was notably more affected than the spinal cord. Incidences w...

The aim of this work was to elucidate the possible role of glucocorticoids in the bacterial lipopolysaccharide (LPS)-induced decrease in hepatic IGF-I synthesis. For this purpose, we studied the effect of LPS on IGF-I in two rat strains, Wistar and Lewis, which have different adrenal responses to inflammation. Compared with Wistar rats, Lewis rats have a reduced hypothalamic-pituitary-adrenal r...

The association of vascular reactivity between diabetes and periodontal disease has not been clarified. Gingival blood flow was measured by laser Doppler flowmetry for 31 weeks in Wistar rats, Wistar rats orally challenged with Porphyromonas gingivalis (Wistar rats + Porphyromonas gingivalis), Goto-Kakizaki rats, and Goto-Kakizaki rats orally challenged with Porphyromonas gingivalis (Goto-Kakiz...

We have recently demonstrated that in large arteries of spontaneously hypertensive rats (SHR), there is no increase of stiffness despite the increase in wall thickness, a sign of mechanical adaptation of the arterial wall to the higher level of stress. Because the dense plaques of smooth muscle are a major site of anchorage between the muscle cells and extracellular matrix, we determined by ele...

AIMS We investigated the effects of hypertension and acute blood pressure changes on rats' vesicovascular reflexes (VVRs). MAIN METHODS Twelve-week-old male Wistar rats and spontaneously hypertensive rats (SHRs) were anesthetized with urethane, and underwent real-time cystometry and blood pressure monitoring. The SHRs were administered nifedipine or valsartan intravenously. The Wistar rats we...

PURPOSE To investigate the expression of αA- and αB-crystallin and heat shock protein 70 (Hsp 70) during curcumin treatment of selenium-induced cataractogenesis in Wistar rat pups. METHODS Group I Wistar rat pups received only saline and served as the control. Group II Wistar rat pups were intraperitoneally injected with selenium (15 µM/kg bodyweight) to induce cataract. Group III Wistar rat ...
