RESUMO
The wound healing is a complex process which, sometimes, can be a problem in public health because of the possibility of physical disability or even death. Due to the lack of a gold standard drug in skin wound treatment and aiming at the discovery of new treatments in skin repair and the mechanisms involved in the process, we used oleoresin (OR) from Copaifera langsdorffii and hydroalcoholic extract of the leaves (EH) to treat rat skin wounds. For that, male Wistar rats were divided into groups (n = 8): Lanette, Collagenase, 10% EH, or 10% OR and, after anesthesia, one wound of 2 cm was made in the back of animals. The wounds were treated once a day for 3, 7, or 14 days and the wound areas were measured. The rats were euthanized and skin samples destined to biochemical, molecular, and immunohistochemical analysis. The results showed a macroscopic retraction of the wounds of 10% EH and 10% OR creams and both treatments showed anti-inflammatory activity. Molecular and immunohistochemical results demonstrated the activity of Copaifera langsdorffii creams in angiogenesis, reepithelialization, wound retraction, and remodeling mechanisms.
RESUMO
No Brasil, as pesquisas sobre o consumo de medicamentos são poucas às vezes com estatísticas não representativas. O propósito deste estudo foi avaliar o consumo de medicamentos em 342 acadêmicos recém ingressos na Universidade. Verificou-se que, em ambos sexos, a cabeça é o orgão mais afetado pela dor, seguida pela coluna vertebral, aparelho genital feminino e o estômago. Para aliviar a dor os medicamentos preferidos foram: Aspirina, AAS, Buscopan, Novalgina, Dorflex, Anador. Em 77 por cento o medicamento utilizado desenvolveu o efeito terapêutico desejado, mas em alguns dos acadêmicos (10 por cento) houve reação adversa ao medicamento. Constatou-se que é rara (68 por cento) a presença de dor, e que o consumo maior de medicamentos foi para o sexo feminino, sendo preferido a Aspirina e o Buscopan
