Methods of Treating Eye Conditions with Human Leukocyte Elastase (HLE) Inhibitory Agents
A method of reducing corneal scarring or fibroblast proliferation comprises applying to an area of a subject\u27s eye afflicted with the condition a corneal scar-fibroblast proliferation-reducing amount of a free or polymer-bound HLE inhibitory agent under conditions and for a period of time effective to attain the desired effect. A method of reducing neovascularization of corneal scar tissue comprises applying to an area of a subject\u27s eye afflicted with the condition a neovascularization-inhibitory amount of a free or polymer-bound HLE inhibitory agent under conditions and for a period of time effective to attain the desired effect

Tobacco Smoke Filter Material
A tobacco smoke filter comprising a imidazole-containing polymer, the imidazole groups being chemically bound to said polymer
3-Hydroxy-N-Methylpyrrolidone and Preparation Thereof
The novel compound, 3-hydroxy-N-methylpyrrolidone, is effective as a transdermal enhancer for the absorption of drugs through the skin of humans and animals. The 3-hydroxy-N-methylpyrrolidone is prepared from delta-butyrolactone which is converted to methyl 2,4-dibromobutyrate, this intermediate is reacted with methylamine to form N-methyl-2,4-dibromobutyramide, this intermediate is converted to 3-bromo-N-methyl-2-pyrrolidone by ring closure, and the 3-bromo-N-methyl-2-pyrrolidone is reacted with an alkaline earth metal carbonate or alkaline metal carbonate to form 3-hydroxy-N-methyl-2-pyrrolidone
Radiodiagnostic Agent
A radiodiagnostic agent comprising a solid, insoluble nontoxic synthetic resin, such as polystyrene, bearing a detectable amount of technetium 99m thereon. This agent is useful for analyzing the gastrointestinal tract, for example, for gastric emptying time, by means of a gamma camera

Polymer Bound Elastase Inhibitors
Pharmaceutical compositions and methods of inhibiting the enzyme elastase and increasing the biological half-life and/or potency in terms of inhibitory activity of the enzyme elastase of peptide compounds is achieved by use of a polymer of the formula P--(L--R)q wherein P is a polymer containing at least one unit of the formula (An Bn) wherein An Bn is substantially nonbiodegradable, and has an average molecular weight of about 1,000 to 5,000 daltons, L is a covalent bond or a linker group and R is a peptide
