Get the neonate Sprague-Dawley rats medulla spinalis, through the conventional primary cell culture procedure, we use the method of difference adherence time and get the motor neurons of anterior spinal cord. When the neuron is in maturity, we make the mechanical injury model in vitro. All the models were divided into four groups: group A is control group; group B is 100μM ATP group; group C is 100μM ATP+20μg/ml suramin group and group D is 100μM ATP+10μM ouabain+10μg/ml Thapsigargin group. Culture the four groups neurons, after one day, we count the motor neuron, observe the survival and activity of neurons through MTT shade selection experiment, use flow cytometry to analyze the percentage of apoptosis of motor neurons of anterior spinal cord and detect the expression of protein p-GSK-3β(ser9) through Western-Blot technology.

The result shows that: the extraction of petroleum ether, polysaccharide and sodium copper chlorophyllin from banana leaves perform higher spumescence ability and foam stability. The critical concentration form pastern namely CMC and the surface tension in this concentration are 1.0 g/l (34.295 mN/m), 1.0 g/l (42.398 mN/m), 3.0 g/l (40.123 mN/m) respectively, which the value is close or excess the reference samples. The emulsify capability of the extraction of petroleum ether is the best in these active ingredients, and close to the emulsify capability of Tween-80. The emulsify capability of polysaccharide and sodium copper chlorophyllin from banana leaves are follow then.
