Effect of exogenous glutamate and N-Methyl-D-aspartic acid on spontaneous activity of isolated human ureter
OBJECTIVES: While the neurotransmitter role of glutamate in the gastrointestinal tract has been shown, its effects on smooth muscle of the human ureter have not previously been investigated. In our study we have investigated the effects of exogenous glutamate on the spontaneous activity of isolated human ureter, taken from 14 adult patients after nephrectomy.METHODS: The segment of ureter, excised
