This study aimed to investigate the effects of hypercholesterolemia on visual evoked potentials (VEPs) and sulfite additional effects. Rats were assigned as follows: control (C), sulfite (S), hypercholesterolemia (H), vitamin E (E), sulfite + vitamin E (SE), hypercholesterolemia + sulfite (HS), hypercholesterolemia + vitamin E (HE), and hypercholesterolemia + sulfite + vitamin E (HSE). Hypercholesterolemic diet led significant increase in plasma cholesterol levels of rats.

Parkinson's disease (PD) is the second most common neurodegenerative disorder marked by cell death in the Substantia nigra (SN). Docosahexaenoic acid (DHA) is the major polyunsaturated fatty acid (PUFA) in the phospholipid fraction of the brain and is required for normal cellular function. Glial cell line derived neurotrophic factor (GDNF) and neurturin (NTN) are very potent trophic factors for PD.

The purpose of this study was to investigate the effects of hypercholesterolemia and sulphite on active avoidance learning. Male Wistar rats were divided into eight groups as follows: Control (C), Sulphite (S), Vitamin E (E), Sulphite + Vitamin E (SE), Hypercholesterolemia (H), Hypercholesterolemia + Sulphite (HS), Hypercholesterolemia + Vitamin E (HE), and Hypercholesterolemia + Sulphite + Vitamin E (HSE). At the end of the experimental period, the serum cholesterol level (mean ± SD) was significantly higher in H group (111.

This study investigated the effect of heme oxygenase (HO) inhibition on visual evoked potentials (VEPs). HO catalyzes the oxidative degradation of heme. Products of HO reaction are biliverdin, ferrous iron, and carbon monoxide (CO).

This article investigated the possible neurotoxic effect of sulfite in normal and sulfite oxidase (SOX) deficients rats by evaluating EEG spectral analysis. Rats were divided into four groups: control (C), sulfite treated (25 mg/kg) (ST), SOX deficient (SD), and sulfite treated SOX deficient (STSD) groups. The qEEG spectral analyses of two spectral parameters including power and relative power were performed.

Sulfite oxidase (SOX) is an essential enzyme in the pathway of the oxidative degradation of sulfur amino acids, and protects cells from sulfite (SO(3)(2-)) toxicity. Rats do not mimic responses seen in human, because of their relatively high SOX activity levels. Therefore, the present study used SOX deficient rats since they are a more appropriate model for studying sulfite toxicity.

Sulfites, which are commonly used as preservatives, are continuously formed in the body during metabolism of sulfur-containing amino acids. Sulfite is oxidized to sulfate ion by sulfite oxidase (SOX, EC. 1.
