Wound healing yeast

We noted earlier in this chapter (Section II.C.3) the pyridoxal-phosphate-linked enzymatic route of synthesis of ACPC (9) from the a-aminobutyryl moiety of S-adenosylmethionine (99). ACPC (9) undergoes further metabolic processing by two distinct fragmentation routes, to a-ketobutyrate (138) and ammonia (equation 21) in bacteria and yeast or to ethylene (139) in fruit and other plant tissues (equation 22) where ethylene (139) is a potent hormone for fruit-ripening or wound-healing The bacterial enzyme, ACPC deaminase is much better characterized and is taken up first.

Free silver ions are the active components of antimicrobial silvers, and it has been shown that as little as one part per million of elemental silver in solution is an effective antimicrobial. Materials such as polymers, charcoal, and hydrocolloids when formulated with silver not only aid wound management and healing but also regulate its release into the wound environment and surrounding tissues. Silver ions kill micro-organisms by inhibiting cellular respiration and cellular function. " It is known that their mode of action is exerted by binding cysteine residues on the cell walls of yeasts such as C. albicans thereby... 

Beta(P)-(l,3)-glucan (53) is a natural polysaccharide comprised of P-(l,3)-glucose-re-peating monosaccharides (Fig. 47) (200,201). It is obtained from yeast fermentation extracts that have been used topically for years to improve the skin s health. Beta-glucan stimulates the immune system and helps to heal wounded or irritated skin (202).
