It is believed that oxidative stress (OS) plays a central role in the pathogenesis of metabolic diseases like diabetes mellitus (DM) and its complications (like peripheral neuropathy) as well as in neurodegenerative disorders like sporadic Alzheimer's disease (sAD). Representative experimental models of these diseases are streptozotocin (STZ)-induced(More)
Low intracerebroventricular (icv) doses of streptozotocin (STZ) produce regionally specific brain neurochemical changes in rats that are similar to those found in the brain of patients with sporadic Alzheimer's disease (sAD). Since oxidative stress is thought to be one of the major pathologic processes in sAD, catalase (CAT) activity was estimated in the(More)
Oxidative stress has been associated with damage and progressive cell death that occurs in neurodegenerative disorders such as Parkinson's disease (PD) and Alzheimer's disease (AD). The aim of this study was to investigate the antioxidant capacity in postmortem motor cortex (MC), nucleus caudatus (NC), gyrus temporalis (GT) and substantia nigra (SN) from(More)
Nitric oxide (NO), a neurotransmitter and a free radical, has been purported to be involved in numerous neurological diseases. We investigated the serum nitric oxide concentration in 30 patients with multiple sclerosis (MS), in 30 patients with epilepsy and in 30 control subjects. The aim was also to determine whether a statistically significant difference(More)
Aim of this study was to evaluate the biotransformation of simple phenols after ingestion of edible fruits and mixed food. It was analyzed hippuric acid in urine as biomarker of conjugation in the liver cells of glycine with aromatic phenolic acids such benzoic and salicylic acid from ingested food. Measurement of hippuric acid in urine samples of 10(More)
Intracerebroventricular (icv) administration of betacytotoxic drug streptozotocin (STZ) produces long-term and progressive cognitive deficits in rats, as well as deficits in cerebral glucose and energy metabolism. These changes resemble those found in the brain of patients with sporadic Alzheimer's disease (sAD), and therefore, STZ-icv treated rats have(More)
UNLABELLED The objective of this study was to evaluate cortisol in the saliva and serum of healthy persons and its daily fluctuations by using immunochemical method on a autoanalyzer. Biological samples: Serum from 14 healthy persons and saliva from 18 healthy persons were taken two times at 8 a.m. and at 4 p.m. Immunochemical assay: The principle of this(More)
In this study for thirty (30) patients with alcohol withdrawal syndrome, the response to anticolvusant gabapentin was assessed. Thirty (30) patients with median age of 57.0 years and median body weight of 79.1 kg were treated with gabapentin 3 x 300 mg daily for up 30 days. The preliminary findings of this study suggest that gabapentin is very effective(More)
The aim of this study was to elucidate the antioxidant behaviour of melatonin (M) and determine its activity-structure relationship. M or 5-metoxy-N acetyltriptamine is a neurohormone secreted by the pineal gland, which plays a proven role in maintaining sleep-wake rhythms. The antioxidant capacity of M was analysed using the oxygen radical absorbance(More)
