  • Publication number: 20070128296
    Abstract: Reactive oxygen species associated with a wound are modulated through treatment of the wound with a solution of metal ions selected from the group consisting of potassium ions, zinc ions, calcium ions and rubidium ions, at a pH of between about 5 and about 7. Preferably, citric acid is employed to adjust the pH of the solution. Application of the extract to a wound exhibiting superoxide anions has been found to be effective in the treatment of these wounds through the reduction of the level of superoxide anions. Moreover, treatment of partial thickness excision wounds as well as contact burn wounds with the present composition has been found to improve epithelialization of these wounds. In addition to the antioxidant activity of the present invention, treatment of the wound employing the present composition produces inhibitory effects on ROS production by human PMNs and on human complement activation, and therefore, is further beneficial in chronic wound management.

  • Patent number: 5349075
    Abstract: The invention provides a process for the esterification of a C.sub.2 -C.sub.24 monocarboxylic acid with a C.sub.1 -C.sub.5 monoalcohol in a reactor at an increased reaction temperature and increased pressure which is carried out in the absence of any esterification catalyst while continuously feeding in the alcohol during the reaction and removing a gaseous alcohol/water mixture. Preferably the process is carried out in countercurrent in column reactor which is packed or contains plates. The reaction temperature is usually between 200.degree. C. and 260.degree. C. at a pressure between 0.5 and 1.5 MPa. There is a C.sub.6 -C.sub.20 monocarboxylic acid and monoalcohol a C.sub.1 -C.sub.3 monoalcohol. More preferably the process is carried in two steps with a first step as described above and a second step in which further reaction to a conversion of at least 99% is carried out in the presence of an esterification catalyst at a temperature below 100.degree. C.
