The conventional management of scalp laceration has its drawbacks. Most patients complain of scalp itching, sticky hair and pain at the time of dressing change, because the washing of the hair is restricted and the wound is covered with gauze before the patients have their stitches removed. In this paper, we report the results of trial given to a new management method. The wound was exposed to the air two days after suturing and washing the hair was allowed at the same time. The trial involved 40 outpatients with scalp laceration. There were no complications of wound infection or delayed healing due to this method. And also most patients (90%) said they felt comfortable. Thus, as an alternative management of scalp laceration this method proved useful for comfortable wound treatment.

High fat diet consumption induces fat accumulation in the liver. An understanding of when liver fat accumulation begins is important for exploring the mechanisms underlying fatty liver. The aim of this study was to investigate the processes of fat accumulation in the liver during high fat diet consumption with or without exercise using computed tomography (CT). Male 6 week old C57BL/6J mice were randomly assigned to the normal diet or high fat diet group. After 6 weeks, mice in the high-fat diet group were further divided into voluntary wheel exercise (HFD+Ex) and no exercise (HFD) groups. We measured body weight, food intake and locomotor activity in all mice. Liver fat accumulation was measured by CT scan weekly. Blood and tissue sampling was performed at the end of the experimental period. Following the 6 week exercise period, total body, mesenteric fat and liver weight in the HFD+Ex group were significantly lower than those in the HFD group. Alanine aminotransferase levels improved in HFD+Ex mice compared with those of HFD mice. The hounsfield unit value in HFD mice decreased between 3 and 8 weeks, suggesting that liver fat accumulation accelerated during this period. In contrast this decrease was not observed one week after exercise in HFD+Ex mice. These results suggest that liver fat accumulation estimated by CT was not observed until the 3rd week of high fat feeding while the effects of voluntary wheel exercise appeared immediately.
