Objective : Effect of treadmill exercise on hippocampal neural cell proliferation under normal conditions and alcohol intoxication conditions has been recently studied; however, this effect under sensory stimulation application has not clarified yet. In the present study, the effect of compression stimulation application on hippocampal neural cell proliferation in the dentate gyrus in normal and alcohol intoxicated rats was investigated. Methods : Experimental design: comparative investigation on number of 5-Bromo-2’-deoxyuridine( BrdU)B-positive cells in dentate gyrus 5 days after commencement. Setting: animal laboratory. Participants: male Sprague-Dawley rats of 3weeks old in age weighing 80±10gm. Intervention: animals were randomly assigned into 4 groups; control-rest group (n=8), control-compression group (n=8), alcohol intoxication-rest group (n=8) and alcohol intoxicationcompression group (n=8). Animals of the alcohol intoxicated groups were injected intraperitoneally with alcohol (2g/kg) twice per day for 3 days. All animals were injected BrdU(50mg/kg) intraperitoneally, and rats compression stimulation application groups were compressed using sphygmomanometer cuff times per day, for 5 days following alcohol administration. Measures: mean number of BrdU-positive cells in dentate gyrus was observed via immunohistochemistry. Results : Compression stimulation application significantly increased the number of BrdUpositive cells in the dentate gyrus. Also, treatment with alcohol for 3 days inhibited cell proliferation, and compression stimulation application alleviated alcohol-induced inhibition of new cell formation. Conclusion : These results suggest the possibility that compression stimulation application may help in improvement following alcohol-induced brain damaged.
