Cell numbers in the parabiliary segment of rat pancreatic tissues

Treatment of rats	β-cells(number/cm2)	α-cells(number/cm2)	δ-cells(number/cm2)
Normal untreated	2086 ± 507	285 ± 85	191 ± 42
90% Depancreatized	442 ± 482	359 ± 120	185 ± 72
90% Depancreatized+nicotinamide(0.5 g/kg per day)	3204 ± 1412**	310 ± 207	133 ± 119
90% Depancreatized+3-aminobenzamide(0.05 g/kg per day)	2286 ± 1173*	310 ± 161	92 ± 42

*P < 0.05 vs. 90% depancreatized rats (control); **P < 0.01 vs. 90% depancreatized rats (control).

The number of cells was determined in the parabiliary segment of at least five rats and expressed as the mean ± SD. Adapted from Refs. 156 and 164.
