title: Elemental composition, water, and total lipid content in peripheral nerves, spinal cord and brain of healthy adult dogs.
abstract: Peripheral nerves, spinal cord, and brain of healthy adult dogs were analysed biochemically for sodium, potassium, calcium, magnesium, copper, zinc, iron, aluminium, silicon, total chloride, total tissue water and total lipid content. Flame atomic absorption spectrophotometry was used for elemental quantitation of the hydrochloric acid tissue extracts. Cerebrum and spinal cord had similar values for all parameters measured. Total sodium values were higher in nerves compared to central nervous system (CNS) (brain and spinal cord), while respective values for potassium were lower. Tissue levels of calcium, iron and silicon were comparable in brain, spinal cord and nerves. However, magnesium concentrations were two to three times higher in CNS than in nerves; and the reverse was true for aluminium levels. Tissue concentrations of zinc and copper were marginally higher in CNS than in nerves.
