PG - 143-55 AB - A combined quantitative enzyme- and immunohistochemical procedure to demonstrate hexokinase (HK) was developed and tested on sections of spinal cord tissue of the zebrafish. In both procedures, the amount of final reaction product was linearly related with section thickness. When applied to serial sections of fish spinal neurons, the enzyme- and immunohistochemical activities appeared to correlate significantly (r = 0.61; p < 0.001). As HK and cytochrome c oxidase (COX) histochemistry have been used regularly to screen the average level of chronic activity of neurons, we subsequently analysed the relationship between HK and COX in fish spinal neurons, using previously published methods of quantitative enzyme- and immunohistochemistry for COX. The enzyme- as well as the immunohistochemical localisation patterns of HK showed a weak correlation with the enzyme- and immunohistochemical COX localisation respectively. Therefore, it is concluded that both enzyme- and immunohistochemical localisation of COX provide a poor estimate for the relative level of glucose utilisation in fish spinal neurons.
