A method of preventing progression of neuropathic pain is disclosed. The method includes administering to a subject an N-type voltage-sensitive calcium channel blocking compound which is characterized by its ability to (a) inhibit electrically stimulated contraction of the guinea pig ileum, and (b) bind selectively to omega conopeptide MVIIA binding sites present in neuronal tissue. Also disclosed are formulations effective to stabilize omega conotoxin peptide preparations at elevated temperatures. Novel omega conopeptides also form part of the invention.

Methods and formulations for preventing progression of neuropathic pain

Disclosed are formulations effective to stabilize omega conotoxin peptide preparations at elevated temperatures. Novel omega conopeptides also form part of the invention.

Stable omega conopetide formulations

A positive photoresist composition containing (i) a quinone diazide polymer formed by reacting a cresol-formaldehyde novolac resin and an o-quinonediazide compound, and (ii) a sulfonamide development enhancement agent.

Positive photoresist composition

A composition of matter including an aqueous solution of hydrofluoric acid or ammonium fluoride and a dye that fluoresces when illuminated by ultra-violet light. Spilled corrosive fluoride solutions are thereby rendered easily detectable by subjecting the surface onto which the solution was spilled to ultra-violet radiation.
