Objective: Walnut (Juglans Regia) is a domestic fruit of Iran. Walnut kernel (WK) has many beneficial constituents such as unsaturated fatty acids, antioxidants, and vitamin E. Scientific studies have shown that fatty acids and vitamin E can modulate learning and memory processes. The aim of the present work was to study effects of walnut consumption by mothers during pregnancy and lactation on...

Introduction: Zinc is an essential trace element that plays an important role in synaptic plasticity and modulating the activity of CNS and involve in learning and memory. Synaptic vesicle zinc in the hippocampus area exerting modulatory effects on NMDA glutamate receptor. Method: In this experiment the effects of NMDA agonist and antagonist administration intra hippocampus on passive avoidan...

Light microscopy of tissue sections stained with cationic iron colloid (pH 1.0-1.5) showed that the adult rat spinal cord contains some neurons which are provided with strongly negative-charged surface coats. These neurons are distributed preferentially in the posterior and intermediomedial columns of the grey matter. The present study thus supplements our previous study of the rat brain (MURAK...

1. The foetal-specific post-albumin of rat plasma was purified by electrophoresis on a Pevicon block. 2. The sedimentation coefficient, diffusion coefficient and molecular weight were determined for this protein and found to be similar to those of adult rat plasma albumin. 3. Foetal post-albumin and adult albumin were compared immunologically and shown, with rabbit antisera, to share no antigen...

Three s|>ecifieembryonic constituents were revealed in the rat serum using rabbit immune sera. These were: a globulin palled Antigen LA, an a2-glycoprotein, and a lipoprotein-esterase. All three antigens were found in embryonic serum, while low titers of the lipoprotein-esterase were found in adult sera. The titers of Antigen LA and the <*2-glycoproteinwere followed in the female rat during ges...

The paired helical filaments (PHFs) in Alzheimer's disease neurofibrillary tangles are composed of PHF-tau which is thought to be hyperphosphorylated because several residues in postmortem samples of PHF-tau and human fetal tau are phosphorylated while the corresponding sites are not phosphorylated in autopsy-derived normal adult human brain tau. To determine how the phosphorylation of these si...

Background: Arsenic toxicity is a major global health problem and exposure via contaminated drinking water has been associated with hematological and other systemic disorders. The present investigation has been conducted in adult male rats to evaluate the protective ability of α-lipoic acid (ALA) against such hematological disorders.Methods: Twenty-four adult male Wister rats (b.wt.130±10g) wer...
