  • Urine every 2 h in all day was consecutively collected from normal and with suprachiasmatic ucleus (SCN) lesions of tree shrews.The circadian rhythm of urination was analysed.The results showed that there was obvious circadian rhythm of urination in normal tree shrews.Uric amount of the day light was (88.52±15.40)% of the all day uric amount.The difference between day and night was rather significant.After SCN lesions,uric amount of the day was(62.86±18.18)% of the total uric amount of the all day.It showed that the circadian rhythm disappeared.In the meantime,the average uric amount of 24hour obviously increased and the uric amount increased at night.It suggested that SCN was an important oscillator of circadian rhythm in the tree shrew.
