    摘要: Quadrol and homologs and analogs thereof have been found to stimulate macrophage activity in warm blooded animals. As a consequence, these compounds may be used to combat bacterial infection, remove degenerated tissue, and promote new tissue growth. Quadrol or a homolog or analog thereof may be applied topically, e.g., as the active agent in a wound dressing. The active compounds may be represented by the formula (I) ##STR1## wherein R.sub.1 and R.sub.2 are substituted alkyl (C.sub.2 -C.sub.6) in which the substituents include one or more hydroxyl groups attached to carbon atoms other than the alpha carbon atom, R.sub.3 and R.sub.4 are alkyl or substituted alkyl (C.sub.1 -C.sub.6), and n=2 to about 6. Preferably R.sub.1 through R.sub.4 are the same and are 2-hydroxyalkyl.

    摘要: Acrylate and methacrylate monoesters and diesters having the following formula (I) ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 are as defined in the specification, are disclosed. These monomers are polymerizable into hydrogel polymers which are extremely hydrophilic. These hydrogel polymers are useful in the preparation of wound dressings. These polymers form complexes with polyvalent metal ions such as Ca, Mg, Mn and Cu, and possess macrophage stimulating activity in addition to the useful properties possessed by other acrylate and methacrylate hydrogel polymers.

These monomers are polymerizable into hydrogen polymers which are extremely hydrophilic. These hydrogel polymers are useful in the preparation of wound dressings. These polymers form complexes with polyvalent metal ions such as Ca, Mg, Mn and Cu, and possess macrophage stimulating activity in addition to the useful properties possessed by other acrylate and methacrylate hydrogel polymers.
