H2S restored the diurnal variations of EF and FS in aging mice. (a) Plasma MDA levels in 18-month-old mice after NaHS treatment. (b) Plasma SOD activities in 18-month-old mice after NaHS treatment. (c) Diurnal variation of EF in 18-month-old mice after NaHS treatment. (d) Mean value of EF during the 12-hour light or dark period in 18-month-old mice after NaHS treatment. (e) Diurnal variation of FS in 18-month-old mice after NaHS treatment. (f) Mean value of FS during the 12-hour light or dark period in 18-month-old mice after NaHS treatment. Results are expressed as the mean ± SEM. A P of <0.05 was considered significant.
