ABSTRACT
ABSTRACT: Considering the benefits that massage can promote, this research aimed to apply the stroking massage in five adult goats (G1-G5) assessed in group and individually for ten days. Parameters related to massage, immune system, physiology and behavior of goats were observed. There was only significant difference (P<0.05) regarding behavior expressed in the presence of the masseur in G4 and G5, between week 1 and 2. Most goats accepted massage, except G2, with greater demonstrations of positive than negative behavior towards the masseur. Therefore, stroking massage promoted positive interactions between the masseur and goats, and should be explored as an alternative method to those existing in improving the relationship between humans and farm animals.
RESUMO: Considerando os benefícios que a massagem pode promover, este trabalho teve como objetivo aplicar a massagem do tipo stroking em cinco cabras adultas (G1-G5) avaliadas em grupo e individualmente por dez dias. Parâmetros relacionados à massagem, sistema imunológico, fisiologia e comportamento das cabras foram observados. Houve apenas diferença significativa (P<0,05) em relação ao comportamento expresso na presença da massagista em G4 e G5, entre as semanas 1 e 2. A maioria das cabras aceitou a massagem, exceto G2, com maiores demonstrações de comportamentos positivos do que negativos direcionados à massagista. Portanto, a massagem do tipo stroking promoveu interações positivas entre a massagista e as cabras, devendo ser explorada como um método alternativo aos existentes na melhora da relação entre seres humanos e animais de produção.
ABSTRACT
ETHNOPHARMACOLOGICAL RELEVANCE: The essential oil of Lippia sidoides (EOLS) has been used in Brazilian folk medicine as a topical antiseptic agent in skin for treatment of wounds and superficial infections of the body. The aim of this study was to investigate the effects of EOLS on intact and damaged skin, including its action on expression of mediators, COX-2 and VEGF, involved in healing full-thickness cutaneous lesions in vivo. MATERIAL AND METHODS: EOLS was analyzed chemically and used at different concentrations to dose-response experiments in skin mice. Skin irritation tests by one-dosage and multiple-dosages and irritation to damaged skin were assessed by macroscopy, morphometry and histological and immunohistochemical analyses. To evaluate the effects of EOLS on wound healing, excision wounds were surgically created on the dorsum of rats, and the ointments at 6% and 12% were applied daily to the wound area. Cutaneous lesions were assessed by planimetric (wound contraction) and macroscopic parameters. RESULTS: Skin irritation tests showed that topical application of EOLS promoted cutaneous inflammation in varying degrees, which was demonstrated by increase of skin thickness and formation of cutaneous edema and erythema. Topical administration of EOLS in high concentrations presented an irritant response to skin, but this irritation is lighter when low concentrations this oil were used. Histological evaluation supported the outcome of these models, which revealed accentuated presence of inflammatory cells infiltration. In wound healing process, the lesions treated with EOLS showed intense edema and exsudation up to day 5, but there were not significant differences in the wound contraction on days 14 and 21. No immunohistochemical staining was verified to COX-2 and VEGF mediators in skin treated with EOLS 12%. CONCLUSION: The continuous application of EOLS in adequate concentrations on cutaneous wounds increases inflammatory response without delay the lesions closure. The association of these results with antimicrobial action previously related to EOLS allows its indication as an alternative therapeutic modality for topical treatment of infected cutaneous wound. Nevertheless, further studies need to be performed to determine the mechanism of action and support its application in clinical practice.
