Quantitative computed tomography was used to determine the radiodensity of bony plates. The CT scans provided information regarding radiodensity of bony plates and allowed to verify the uniformity of bone mineral density in their scope. The proposed methodology should be considered as another tool for determining the resistance of these biomaterials.

Avaliaram-se os efeitos analgésicos da eletroacupuntura, aquapuntura e farmacopuntura com morfina nos acupontos VB41 e TA5 de 24 cadelas hígidas submetidas à ovário-histerectomia. Os animais foram distribuídos em quatro grupos (G) de igual número - GDest, GMorf, GElet e GC - e anestesiados com acepromazina, propofol e isofluorano. Após a estabilização do plano anestésico, os animais do GDest receberam 0,5mL de água destilada em cada acuponto; os do GMorf receberam 0,1mg/kg de morfina distribuído nos quatro acupontos; os do GElet foram submetidos à eletroacupuntura; e os do GC, acupuntura em pontos sham. Os animais do GC receberam, após o término do procedimento cirúrgico e antes do início da avaliação pelas escalas de dor, 2,0mg/kg de tramadol. Foram avaliadas: frequências cardíaca e respiratória, temperatura retal e glicemia. A dor foi avaliada por duas escalas, uma de analogia numérica e outra contagem variável, por três observadores. A avaliação iniciou-se imediatamente após a extubação e foi realizada a cada 15 minutos, durante duas horas. Não houve diferença entre os tratamentos em todas as variáveis. Pode-se concluir que eletroacupuntura, aquapuntura e farmacopuntura com morfina resultaram em analgesia similar ao tramadol no pós-operatório imediato de cadelas submetidas à ovário-histerectomia eletiva.

In order to evaluate the analgesic effects of electro-acupuncture, aquapuncture and morphine pharmacopuncture on VB41and TA5 acupoints, 24 healthy bitches were anesthetized with acepromazine, propofol and isoflurane and underwent ovariohysterectomy. The animals were equally divided into four groups: GDest, GMorf, GElet and CG. After anesthetic stabilization, GDest animals received pure water (0.5ml per acupoint); GMorf received morphine (0.1mg/kg); electroacupuncture was performed in GElet animals, and CG animals were submitted to acupuncture on Sham points. The CG animals received 2.0mg/kg of tramadol after the end of surgery and before the postoperative evaluation through pain scales. Data recorded were: heart and respiratory rate, rectal temperature and blood glucose. Pain was assessed using two different scales, one using numerical analogy and another using variable counting, both performed by three different professionals. Evaluation started immediately after the animal was extubated and was performed every 15 minutes, for 2 hours. There was no statistical difference between groups in all variables studied. It is concluded that electro-acupuncture, aquapuncture and morphine pharmacopuncture produce analgesia similar to tramadol in the postoperative period of bitches undergoing elective ovariohysterectomy.
