Figure 7

β-cell mass was determined in pancreatic sections from BB rats treated with vehicle (white bars) or L-NMMA (black bars) at 7 and 9 weeks of age. β-cell mass is presented in the bar graph as means ± SEM of values calculated as the ratio of insulin-positive area/total pancreatic area multiplied by the total pancreatic weight. Values are obtained from a mean of 5 animals. treated versus control.
