Figure 2. Relation between streptozotocin dose and pancreatic insulin content, recorded from 24 h to 35 days after the streptozotocin injection in rats. Data were obtained from (Junod et al., 1967, 1969; Stauffacher et al., 1970; Robbins et al., 1980; Rodrigues et al., 1997). In the case that data was presented in a graph, values were extracted using Photoshop, as previously reported (Gheibi et al., 2019).
