Single layered nonwoven wound dressings containing (1) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (2) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (3) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %. Also, multi-layered nonwoven wound dressings, containing (1) at least one inner layer containing (a) about 50% by weight to about 95% by weight (e.g., 50% to 95) non-scoured, non-bleached greige cotton fibers and (b) about 5% by weight to about 50% by weight (e.g., 5% to 50%) hydrophobic fibers, all percentages adding up to 100 wt %, and (2) at least one outer layer containing (a) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (b) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (c) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %.

Flexible and absorbent alginate wound dressing

The invention provides wound dressings and methods of their use, especially for the treatment of chronic, non-healing wounds. The wound dressings are composed of a support matrix, such as cotton cellulose, and an active agent associated with the support matrix. The active agent may be a protease inhibitor or a protease sequestrant, in particular an inhibitor or sequestrant of a neutrophil-derived cationic protease such as elastase.

Preparation of peroxide-oxidized, sulfonated, and phosphorylated cotton

The following novel oligopeptide compounds which possess phytotoxic and plant growth regulating properties and methods for their use are disclosed: R.sub.1 -N(R.sub.2)-D,L-Ala-D,L-Leu-N(R.sub.2).DELTA.Phe-Gly-OR.sub.3 ; in which R.sub.1 is H or a protecting group at the amino terminus of the type 9-fluorenylmethoxycarbonyl, or benzyloxycarbonyl, R.sub.2 is an alkyl of 2 to 3 carbon atoms, R.sub.3 is hydrogen or an alkyl of 2 to 3 carbon atoms, and .DELTA.Phe is dehydrophenylalanine. R.sub.1 -D,L-Leu-N(R.sub.4)-.DELTA.Phe-Gly-OR.sub.3 ; R.sub.1 Aib-N(R.sub.2)-.DELTA.Phe-Gly-OR.sub.3 ; R.sub.1 -Ala-N(R.sub.5)-.DELTA.Phe-Gly-OR.sub.3 ; R.sub.1 -Val-N(R.sub.2)-.DELTA.Phe-Gly-OR.sub.3 ; wherein R.sub.1 is H or a protecting group at the amino terminus of the type tert-butyloxycarbonyl-(BOC), 9-fluorenylmethyloxycarbonyl, or benzyloxycarbonyl, R.sub.2 is an alkyl of 1 to 3 carbon atoms, R.sub.3 is hydrogen or an alkyl of 1 to 3 carbon atoms, and .DELTA.Phe is dehydrophenylalanine.
