ABSTRACT
The ozone is effective against most microorganisms due to its high oxidant power. Low concentrations and short-term contact are sufficient to inactivate bacteria, mold, yeast, parasites, seaweeds, protozoa and fungi. Microsporum canis is an important agent of dermatophitosis in human and animal. The aim of the current study was to assess the efficacy of ozonized oil over Microsporum canis in rabbits. Eighteen male New Zealand white rabbits, weight ranging from 2 to 3.2 kg were depilated in the cranial dorso-lateral and right caudal, and cranial and left caudal regions. The regions were inoculated with Microsporum canis, excepting the right caudal region, and were denominated TM, O, OM and M, respectively. After seven days, the treatment of lesions in TM began with 0.12g of terbinaphine 1 percent cream; in OM and O with 0.12g of ozonized oil; all animals were treated once a day for 28 days. Region M was not treated. Material was collected from those regions for cultivation in Sabouraud agar at day 28 of treatment. In the evolution of the treatment with terbinaphine, of 14 contaminated regions with Microsporum canis ten evolved to cure. With the ozonized oil, of 15 contaminations, four were cured. Clinically, that is, the macroscopic evaluation of lesions showed improvement in the TM and OM treated regions. We can conclude that there was statistical evidence of the protection action of the oil against the dermatophyte.

PURPOSE: Compare the parietal peritoneum suture and nonsuture in midline laparotomies in rats, as for the formation of adhesions. METHODS: 40 adult albino Wistar rats (20 males and 20 females) underwent a surgery, weighing between 350 and 400 grams. After anesthesia, a midline laparotomy was performed, followed by cavity closure with and without peritoneum suture. After 40 days, the rats underwent a new surgery in order to verify the peritoneum and check if there were any adhesions, and the rats were then sacrificed. RESULTS: Statistical analysis showed there was no significant difference between the adhesions occurring or not with peritoneal suture or nonsuture, including in relation to the rats' gender. CONCLUSION: Closing the peritoneum or not does not interfere with the formation of adhesions after midline laparotomies in rats from both genders.
OBJETIVO: Comparar a sutura e não sutura do peritônio parietal nas laparotomias medianas em ratos, quanto à formação de aderências. MÉTODOS: Foram operados 40 ratos albinos Wistar (20 machos e 20 fêmeas), adultos, pesando entre 350 e 400 gramas. Após a anestesia, foi realizada laparotomia mediana seguida de fechamento da cavidade com sutura do peritônio e sem sutura do peritônio. Após 40 dias, os animais foram re-operados para a inspeção do peritônio e a constatação da presença ou não de aderências e, em seguida, sacrificados. RESULTADOS: A análise estatística demonstrou que não houve diferença significativa entre a ocorrência ou não de aderências com sutura e não sutura do peritônio, nem com relação ao sexo dos animais operados. CONCLUSÃO: O fechamento ou não do peritônio não interfere na formação de aderências após laparotomias medianas em ratos de ambos os sexos.
