Characteristics of non-diabetic (NDM) and diabetic (DM) rats
| Bodyweight (g) | Heart weight (g) | Heart weight/ Body weight × 100 (%) | Blood glucose level (mg/dL) | |
|---|---|---|---|---|
| NDM (n = 36) | 314 ± 18 | 1.032 ± 0.076 | 0.329 ± 0.020 | 127.8 ± 16.2 |
| DM without insulin treatment (n = 36) | 279 ± 22a | 0.967 ± 0.062 | 0.349 ± 0.024 | 484.2 ± 57.6a |
| DM with two-day insulin treatment (n = 24) | 294 ± 11a | 1.010 ± 0.076 | 0.344 ± 0.024 | 262.8 ± 41.4a,b |
| DM with two-week insulin treatment (n = 24) | 353 ± 15a,b,c | 1.206 ± 0.071a,b,c | 0.342 ± 0.024 | 127.8 ± 25.2b,c |
Data were analyzed between groups using one-way ANOVA. Bodyweight and blood glucose level were measured at the day of experiment and heart weight were measured immediately after excision. Data are presented as mean ± SD.
NDM: non-diabetic rats; DM: diabetic rats; Ins-S: two-day short-term insulin treatment; Ins-L: two-week long-term insulin treatment.
a
P < 0.05 compared with the NDM group; bP < 0.05 compared with the DM without insulin treatment; cP < 0.05 compared with the DM with two-day insulin treatment group.
