ABSTRACT

Introduction: wound healing is a significant healthcare problem in today's medical practice. Several courses of treatment are suggested for healing, including the use of medicinal plants. The green foliage of Pinus caribaea var. caribaea, an abundant plant in Cuba, presents varied chemical composition.
Objective: to evaluate wound healing activity of chlorophyll carotene paste from green foliage of Pinus caribaea var. caribaea in open wounds in rats, using two Rhizophora mangle L. formulations with proved wound healing effect as positive controls.
Methods: Wistar rats of both sexes, distributed into 4 groups of 4 rats each, were used and they were intentionally wounded. In the control group, the sterile water as vehicle was topically administered where in the other 3 groups, the chlorophyll carotene paste, CIKRON and gel from R. mangle were daily applied for 11 days. The wound area was measured on the first day, 8th and 11th days; in addition to clinical evaluation of the condition of the rats, which were slaughtered at the end of the experiment. A histopathological study was conducted with their skin. The statistical exaluation was based on variance analysis, Duncan´s multiple comparison and chi square.
Results: the healing effect of chlorophyll-carotene paste was significant since the wound areas were substantially reduced at 8th and 11th days and clinical signs did not appear. The histological study revealed a high percentage of wounds in healing Phase II of the epidermis and dermis in all the groups. The group treated with chlorophyll-carotene paste showed the greatest portion of histological parameters in healing phases I and II with respect to the rest of the groups.
Conclusions: the favourable effect of chlorophyll carotene paste from green foliage of Pinus caribaea var. caribaea in the open wound healing was demonstrated, which is comparable to that of the drugs from Rhizophora mangle L.
