Individual housing and social isolation means falling apart from fellow in man and social animals is considered one powerful stressful event through several studies that has been shown negative effects of individual housing on various aspects of physiological function of living organisms such as laboratory, domestic and farm animals. In this study 20 mice (10 male and 10 female) have been divided into 2 groups (social and individual housing) and have been maintained for one month in this condition then the rate of chronic pain were measured with formalin test. The results indicated reduction of chronic pain in male and female individually housed mice but this reduction was significantly greater in male mice. For understanding mechanisms involved in this process, further studies in the fields of neurochemical changes due to social isolation and sex differences in behavioral changes induced by social isolation are recommended.

Ear disease is one of the main problems in small animal field. The various therapies have been recommended for ear disease. Medical treatment is sometimes are insufficient and the response is not curative, therefore, surgical treatment is suggested. An eleven-year-old, German shepherd dog weighing 27 kg with weakness, loss of appetite and left side head tilt had been referred to small animal clinic. During nine months period, several courses of medications had been prescribed for this patient but all the medical treatments were unsuccessful. According to patient signalment, surgical treatment was suggested. After patient and operation team preparation, anesthesia was induced and the surgical procedure was carried out with vertical and horizontal canal ablation. Lateral bulla osteotomy was performed using surgical hand-piece. The copious irrigation was done and plate-form pus organized removed from floor of bulla and the Incision lines were sutured routinely. After 48 hours of supportive treatment, clinical signs improved and the patient returned to normal life. One year follow-up showed no head tilt.
