ABSTRACT: Comparative effect of a phytotherapeutic product from Brassica sp as cicatrizing. The use of the phytotherapy is very old, and now it is expanding all over the world. New phytotherapeutic products have to have its effects certificated in the scientific bases, including toxicological studies, what justifies the use of biological experiments. In this work the effect of a phytotherapic product from Brassica sp (Phytoderminâ) was compared to a standard industrialized product (Kollagenaseâ) on the wounds cicatrization rates in surgically induced animals. The tests were carried out using nine animals (Cavia cobaya), weighing around 500 to 600 grams. The hair of the lateral right of each animal was removed mechanically. All animals received a local anesthesia with 0.5 mL of lidocain 2% plus fenilferin 1:1000. After that, a surgical incision of approximately 2.0 cm2 of diameter was made. The animals were treated with the ointments of the two products (Phytoderminâ and Kollagenaseâ), applied twice a day until the end of the cicatrization process. The control animals group was treated only with physiologic saline. The experiment was made using three animals per group. The cicatrization rate was accompanied by measuring the length and the width of the wounds daily. The cicatrization of the wounds takes place in approximately twenty days. In the control animals treated with none of the tested products it was observed a delay in the cicatrization process. With the data of cicatrization evolution, it was possible to adjust one curve for each treatment, with aid of the lineal model. The values of the rates estimated in each treatment were compared using Tukey test (p=0.05). The cicatrization rates obtained with use of Phytoderminâ and with Kollagenaseâ didn’t differ from each other, although both rates was larger than the one observed in the control animals, suggesting that the phytotherapeutic product (Phytoderminâ) used to heal the wounds had similar effect of the commercial industrialized product (Kollagenaseâ). Key words: phytotherapy, Cavia cobaya, plant extract, wound healing. INTRODUCTION The human kind has been using plants with therapeutic purposes since remote times, and its use is expanding now all over the world. However, for consume of medical plants settle down is necessary the use of experimentation and scientific validation of the current therapeutic dose and monitoring the collateral effects of its use (Elizabetsky, 1987). These currents need justifying the accomplishment of biological tests. According Clark (1993), the events of the wound cicatrization can be divided in three phases that are not mutually excluding, but put upon in the time. These phases are nominated of inflammatory stage, with a pick in the first hours after the injury, preceded by granulation and later on for epithelization (Politis & Dmytrowich, 1998). The cicatrization process is characterized by the fouling of the wound and closed by the scar. However, these stages can be altered by the presence or absence of some Recebido para publicação em agosto/2004 Aceito para publicação em julho/2006 bacteria, wound type (open or close), degree of sanguine supply, type of tissue and others one (Manjo & Joris, 1996). From the natural substances normally used for the cutaneous wound repair, it is possible to stand out the honey (Oryan & Zaker, 1998), the proplis (Silveira & Raiser, 1995), and Aloe Vera’s leaves (Chitahra et al., 1995). Several plants are also used like “Alecrim”, “Babosa”, “Barba-Timão”, “Calêndula”, “Cardo-Santo”, “Espinheira-Santa”, “Mil-Folhas” and “Tanchagem”. These plants, in spite of be used thoroughly they lack of deeper studies in the clinical and pharmacotechnics aspects. The use of Brassica is reported by Balbach and Boarim (1993) that suggested it to be used for the treatment of several illnesses as abscesses, hemorrhoids, facial and dental nevralgy, intestinal disturbances and wounds in general. These authors (Balbach and Boarim, 1993) refer to coming information of the year of 1881, when Dr. Blanc, of the University of Paris published classic work about the use of the cabbage, entitled “Les propriétès médicales de la feville de chou “ (The medicinal properties of the cabbage leaf).

Evolution of the cicatrization process of wounds in Cavia cobaya, treated with KollagenaseÒ, ointment of Brassica sp. and with saline solution (control). TABLE 1. Rate values of cicatrization calculated for each treatment, and the coefficient of regression determination (R2). It was used nine white adult animals (Cavia cobaya), of both sexes, weighing around 600g and purchasing from LARA (Regional Laboratory of Animal Facilities), Pedro Leopoldo-MG, Brazil. The animals were feeded with food and water ad libitum. They were randomly separated in three groups with three individuals each. Each cage contained an animal and it was properly identified. The first group received a plant extract from Brassica sp healing ointment PhytoderminÒ, the second group received a standard industrialized healing ointment KolagenaseÒ and the third, NaCl 0.9% saline solution (control group). The hair of the lateral right of each animal was removed with the aid of an electric shaver. The surgical wounds was induced using aseptic techniques and each animal received local anesthesia of lidocain 2% plus fenilefrin 1:1000 in the muscle in the dose of 0.5 ml approximately. The surgical wounds had approximately a area of 2.0 cm2. The wounds were obtained by the removal of the skin and of the subcutaneous tissue. The borders of the wounds were measured and the data individually logged. In all animals the surgical procedure was accomplished by the same person. The animals received the treatments twice a day, until the complete cicatrization of the wounds. The wounds were measured daily. To the cicatrization curve in function of the time was adjusted of lineal regression with the objective of esteeming the mean of the rate cicatrization for each treatment. The cicatrization rate was obtained and compared statistically. RESULT AND DISCUSSION The present work has for objective to study the effectiveness of the healing ointment developed by the handmade pharmacy. This phytotherapic product (PhytoderminÒ) is obtained starting from the plant extract of Brassica sp (BrassiskinÒ). The cicatrization curve of the wounds submitted to the different treatments can be observed in the Figure 1. In the monitored animals, the cicatrization happened around twenty days. The cicatrization process was slower in the controls treatment. Based in the curve of cicatrization evolution, it was possible to estimate the cicatrization rates for each treatment, with aid of the lineal model (Table 1). Based on the values of the rate for each treatment, the comparative test of average (Tukey, p=0.05) was applied. It was possible to verify that the TABLE 2. Comparison among the cicatrization rates for the treated wounds with KollagenaseÒ, ointment of Brassica sp and with saline solution (control). Obs.: Average proceeded by the same letter doesn’t differ to each other by the Tukey´s test (P>0.05) Rev. Bras. Pl. Med., Botucatu, v.8, n.esp., p.136-138, 2006. 138 cicatrization rates obtained with use of the ointment of Brassica sp. (PhytoderminÒ) and, KollagenaseÒ didn’t differ significantly to each other. Both rates were larger than the rate observed in the controls treatment (Table 2), suggesting that the phytotherapeutic product (Phytoderminâ) used to heal the woods had similar effect of the commercial industrialized product (Kollagenaseâ).
