?-Endorphin cells in the rat gastric antrum and effect of long-term stress on the number of ?-endorphin cells in the pituitary gland and gastric antrum were studied with PAP method and on the basis of stereological principle.The results showed that after long-term stress in rats, the number of ?-endorphin cells in the pituitary gland were significantly increased but decreased in the gastric antrum.

Objective　To evaluate whether the stimulation on eyes of bendazac lysine eyedrops could be reduced by cold storage.Methods　 Mate design scheme and double-blind clinical trial were performed. 160 healthy eyes was divided into two groups: the test group was given bendazac lysine eyedrops which was stored in refrigerator at 4℃ over night, and the control group was given it which was stored at room temperature.Results　ln the control group and the test group, the occuring rate of stimulation was 19.30% and 6.25%. The cases of B、C stimulation degrees were 31 and 10; the average stimulation degrees of each group were 1.21 and 1.07, the scoring change for eye stimulation were 1.57±1.50,0.79±1.40,all respectively. The statistical difference was significant (P＜0.05 or P＜0.01).Conclusion　The eye stimulation of bendazac lysine eyedrops can be reduced by cold storage.
