          Abstract

          Background

          In Indian traditional system of medicine Celastrus paniculatus extract has been used to improve intellect, memory and for the treatment of various mental disorders.

          Purpose

          The present study was undertaken to evaluate the effectiveness of this medicinal plant on serum biochemistry.

          Methods

          Ethanolic extract of seed of Celastrus paniculatus (2g/kg/body weight) was orally administrated for 16 days in 20 months old albino rats. The results were compared with 3 months, 12 months and 20 months old control rats. The concentration of trace elements was determined by atomic absorption spectrophotometer.

          Results

          Significant variation was observed in the concentration of trace elements. In case of copper there was decrease in content in early aged (0.240 ± 0.004) control and age control (0.115 ± 0.004) rats whereas an increase in treated aged rats (0.124 ± 0.004) was observed. Non significant variation was observed in zinc content. Young control rats possessed 0.683 ± 0.004 (µg/ml) zinc contents in cerebellum. Age control animal showed the highest level of Zn 0.954 ± 0.002. Celastrus paniculatus treated rat show revealed the lowest level of zinc 0.457 ± 0.003 (µg/ml) in cerebellum. Young control rat had 0.066 ± 0 (µg/ml) manganese content which was significantly decreased in early age control (0.022 ± 0.0008) followed the significant increase in age control (0.087 ± 0.002). Treated rats possessed the decreased content than age control but higher than young and early age control. Non significant decrease in cobalt content was observed during ageing as in young control the highest cobalt content was 0.084 ± 0.0007 followed by decrease in early age control 0.83 ± 0 and age control 0.006 ± 0.0007 (µg/ml). Treated rats showed an increase in cobalt content up to 0.032 ± 0.0007.

          Conclusion

          Results of the present study revealed that the determination of trace elements in blood and tissues has been widely used in the last two decades as a tool to understand their metabolic role in human and animals.

          The essential trace elements.

          W MERTZ (1981)
          Essential trace elements are required by man in amounts ranging from 50 micrograms to 18 milligrams per day. Acting as catalytic or structural components of larger molecules, they have specific functions and are indispensable for life. Research during the past quarter of a century has identified as essential six trace elements whose functions were previously unknown. In addition to the long-known deficiencies of iron and iodine, signs of deficiency for chromium, copper, zinc, and selenium have been identified in free-living populations. Four trace elements were proved to be essential for two or more animal species during the past decade alone. Marginal or severe trace element imbalances can be considered risk factors for several diseases of public health importance, but proof of cause and effect relationships will depend on a more complete understanding of basic mechanisms of action and on better analytical procedures and functional tests to determine marginal trace element status in man.

            Requirements and toxicity of essential trace elements, illustrated by zinc and copper.

            Early signs of toxicity of essential trace elements are important. Some trace elements are available over-the-counter (OTC) and/or are present at industrial waste sites. Physicochemically similar trace elements compete for ligands, impairing functions, which is exemplified by the zinc-copper antagonism described long ago by Van Campen, Hill and Matrone, and Klevay. Intestinal absorption of copper is inhibited by zinc. Thus risk of copper deficiency is increased when the molar ratio of zinc to copper (Zn:Cu) is high. As shown by experiments, copper deficiency can occur in humans. Manifestations include decreased erythrocyte copper-zinc superoxide dismutase, increased low-density-lipoprotein cholesterol, decreased high-density-lipoprotein cholesterol, decreased glucose clearance, decreased methionine and leucine enkephalins, and abnormal cardiac function. Calculation of a preliminary reference dose for OTC zinc that assumed high bioavailability and uncertain copper intakes established 9 mg as a safe amount for 60-kg adults.

              Melatonin protects SHSY5Y neuroblastoma cells from cobalt-induced oxidative stress, neurotoxicity and increased beta-amyloid secretion.

              Heavy metals are increasingly being implicated as causative agents in neurodegenerative diseases such as Alzheimer's disease (AD). Cobalt, a positively charged transition metal, has previously been shown to be in elevated levels in the brain of AD patients compared with age-matched controls. In this study, we investigate the effects of cobalt as an inducer of oxidative stress/cell cytotoxicity and the resultant metabolic implications for neural cells. We show that cobalt is able to induce cell cytotoxicity (reduced MTT metabolism) and oxidative stress (reduced cellular glutathione). The pre-treatment of cells with the pineal indoleamine melatonin, prevented cell cytotoxicity and the induction of oxidative stress. Cobalt treatment of SHSY5Y cells increased the release of beta-amyloid (Abeta) compared with untreated controls (ratio Abeta 40/42). Melatonin pre-treatment reversed the deleterious effects of cobalt. These findings are significant as cobalt is an essential nutritional requirement, usually bound to cobalamin (vitamin B12), for all animals which in the unbound form could lead to neurotoxicity.
