An atomic absorption spectrophotometer with furnace atomizer is                 essential for ultra-micro elemental measurements in three                       different research projects.  It will be used to determine metal                content (particularly zinc and iron) in hippocampal slices.  The                objective is to investigate the relationship of tissue metal                    content to neuronal damage in the brain during exposure to                      oxidative stress.  Another project will use this equipment to                   measure sodium and potassium concentrations in nanoliter samples                of tubular fluid from neonatal rat kidneys.  The measurements                   will be used to assess the role of atrial natriuretic factor in                 water and electrolyte homeostasis in the immature rat.  For the                 third project, the atomic absorption spectrophotometer will also                be used to determine sodium and potassium concentrations in                     nanoliter samples of renal tubular fluid.  The role of                          neurohumoral factors, particularly dopamine, regulation of sodium               excretion in neonatal rats will be examined.                                                                                                                    The atomic absorption spectrophotometer and graphite furnace                    atomizer offers the unique capability of measuring the content of               various metals and ions in extremely small samples of tissue and                fluid at a reasonable cost.
