Table 1.

The effects of old age on the sinusoidal diameter (determined by electron microscopy) and sinusoidal density, intersinusoidal distance and distance between adjacent central veins (determined by light microscopy). The figures in parenthesis refer to the number of observations in livers from 4 young and 4 old rats.

Parameter	Young	Old
Sinusoidal diameter (μM)	9.4±3.6 (n=977)	9.7±3.5 (n=1225)
Intersinusoidal distance (μM)	16.1±3.9 (n=567)	15.5±3.8^* (n=558)
Number of sinusoids per 100 μM²	17.5±2.5 (n=56)	17.4±4.1 (n=58)
Distance between central veins (μM)	809±199 (n=79)	891±190^** (n=78)
