Larvae stained using the NADPH diaphorase assay were initially fixed in a 2% glutaraldehyde, 1% formaldehyde solution in phosphate buffer pH 7.
Under appropriate regulation, their presence would allow for the observed increase in NADPH diaphorase activity during larval development (6) and account for the strong NOS immunoreactivity observed in the cell bodies of the apical ganglion (7).
The following polymorphic enzyme systems were assayed in two running buffers as described in Ritland and Ganders (1987): isocitrate dehydrogenase, triphosphoisomerase, 6-phosphoglucose dehydrogenase, phosphoglucomutase, phosphoglucoisomerase, aconotase, aspartate aminotransferase, diaphorase (2 loci) and esterase.

The immature activity of the enzyme diaphorase in their erythrocytes makes infants more prone to methemoglobinemia in such circumstances; nonetheless, as my colleagues and I recently showed, even in preterm infants, applying EMLA before heel pricking does not produce methemoglobinemia [19].

Using the same experimental paradigm in two independent studies, we have found that nicotinamide adenine dinucleotide phosphate diaphorase (NADPH)+ neurons are reduced about 10% (Fernandez et al.
It was observed recently that the administration of Ascaris sun extract (Asc) in infected mice increased NADPH diaphorase activity and TNF-[alpha] levels in the early phase of BCG infection (Ferreira et al.

NADPH diaphorase histochemistry indicated NOS activity in cells in the lower lip of the larval mouth, the preoral hood, the gut, and in the tube feet of the echinus rudiment.
An additional 19 enzymes (acid phosphatase, alcohol dehydrogenase, aldolase, catalase, diaphorase, endopeptidase, esterase, formate dehydrogenase, fluorescent [Beta]-galactosidase, glucose-6-phosphate dehydrogenase, [Beta]-D-glucosidase, glutamate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase, isocitrate dehydrogenase, lactate dehydrogenase, malic enzyme, peroxidase, phosphoglucomutase, and sorbitol dehydrogenase) were studied, but excluded from the analysis because of inconsistent activity.
