BACKGROUND： The pathophysiological mechanisms of ischemia are extremely complicated. It is difficult to confirm and maintain the therapeutic effects if only one neuroprotective agent is used. It is hypothesized that a cocktail therapy involving a combined application of neuroprotective agents is feasible and offers excellent therapeutic potential. OBJECTIVE： To evaluate the neuroprotective effects of a cocktail therapy of insulin-like growth factor 1 （IGF1） combined with anti-intercellular adhesion molecule 1 （ICAM1） antibody in the treatment of cerebral ischemia/reperfusion injury using medical imaging, pathology, and functional neurological deficit scoring techniques. DESIGN, TIME AND SETTING： This randomized, controlled, neuroimaging analysis of function and pathological observation was performed at the Laboratory of Molecular Imaging, Second Hospital, Hebei Medical University between September 2006 and December 2007. MATERIALS： Transient middle cerebral artery occlusion （MCAO） was induced in 24 healthy adult cats. Anti-ICAM1 antibody and IGF1 were sourced from the Shanghai Kangcheng Biological Product Co., Ltd., China. Stereotaxic apparatus was purchased from the Center for Medical Apparatus and Instruments, Shandong Liaocheng People＇s Hospital, China. The in situ apoptosis kit was provided by the Beijing Zhongshan Biotechnique Co., Ltd., China. METHODS： Twenty-four cat models of MCAO were randomly divided into four groups （n = 6）： control, IGF1, anti-ICAM 1 antibody and cocktail therapy. Following a 2-hour ischemia and subsequent lateral cerebral ventricular puncture, 100 μg IGFl（cerebral ventricular）, 100 μg anti-ICAM1 antibody （i.v.）, 50 μg IGFl（lateral cerebral ventricular）＋ 50 μg anti-ICAM1 antibody （i.v.）, and 100 μg physiological saline （i.v.） were administered to the IGF1, anti-ICAM1 antibody, cocktail therapy and control groups, respectively. On the following day, the same administration was performed again. MAIN OUTCOME MEASURES： Pathological observat
