A direct and continuous kinetic method for the fluorimetric assay of various hydrolases by using new, highly water-soluble substrates is described. The latter consist of esters of strongly fluorescent 1-hydroxypyren-3,6,8-trisulfonic acid trisodium salt with acetic, butyric, caprylic, and oleic acid.

Mounting evidence points to individual contributions of tumour necrosis factor-alpha (TNF) and the c-Jun N-terminal kinase (JNK) pathway to the induction and maintenance of various pain states. Here we explore the role of spinal TNF and JNK in carrageenan-induced hypersensitivity.
