OBJECTIVETo investigate the protective effects of carnosine against experimental closed head injury (CHI) in mice.

METHODSThe CHI model was established by free-falling weight-drop. Carnosine (250 mg/kg or 500 mg/kg) was administered intraperitoneally 30 min before brain trauma, then q.d for 7 d; while normal saline was administrated for control group. The neurological defect was evaluated by neurological severity score (NSS) within 7 d; the survival rate and the histological alternations were observed.

RESULTSCarnosine prevented the body weight loss of mice at dose of 500 mg/kg; significantly increased the survival rate, and reduced the neurological defect and histological damage at dose of 250 and 500 mg/kg.

CONCLUSIONCarnosine can attenuate closed head injury in mice.

With the continuous advancement of modern research on tongue diagnosis in traditional Chinese medicine,tongue diagnostic equipment plays an undeniable role in promoting the objectification of tongue diagnosis.Traditional Chinese medicine tongue diagnosis is only the subjective judgment of clinical doctors on tongue color,coating,etc.,while digital tongue diagnostic equipment and digital image processing technology can visually display tongue color,coating,etc.through digital representation,obtain the color distribution of the tongue body,saturation,brightness,and other parameter values of tongue color,objectively reflecting physiological and pathological changes in the body.The article briefly introduces the main working principles,technical parameters,image segmentation processing methods,and tongue image analysis techniques of digital tongue diagnostic equipment.It focuses on summarizing the research status of digital tongue diagnostic equipment in promoting the objectification of traditional Chinese medicine tongue diagnosis in some common diseases,and looks forward to the future application and development of digital tongue diagnostic equipment.
