Percentage (%) of of Des‐Neg, Des‐Pos, DysC‐Neg and DysC‐Pos fibers in UV and PP.
| Muscle | Random areas | Specific areas | ||
|---|---|---|---|---|
| % | SD | % | SD | |
| UV (n = 3453 muscle fibers) | ||||
| Des‐Pos, DysC‐Pos | 86.8 | 12.5 | 64.9 | 26.3 |
| Des‐Neg, DysC‐Neg | 2.7 | 2.3 | 20.4 | 26.7 |
| Des‐Neg, DysC‐Pos | 9.0 | 12.9 | 8.3 | 8.7 |
| Des‐Pos, DysC‐Neg | 1.5 | 1.0 | 6.4 | 8.5 |
| PP (n = 2920 muscle fibers) | ||||
| Des‐Pos, DysC‐Pos | 88.8 | 3.7 | 60.4 | 31.3 |
| Des‐Neg, DysC‐Neg | 5.0 | 3.2 | 17.1 | 19.7 |
| Des‐Neg, DysC‐Pos | 4.8 | 3.7 | 15.7 | 17.9 |
| Des‐Pos, DysC‐Neg | 1.4 | 0.4 | 6.8 | 7.5 |
The mean percentage values are obtained from random areas of the entire muscle cross‐section of each sample, and from selected areas with an abundance of Des‐Neg and DysC‐Neg fibers, respectively. The quantitative analysis is based on adult samples from normal subjects.
Des‐Neg, desmin negative; Des‐Pos, desmin positive; DysC‐Neg, dystrophin C‐terminal negative; DysC‐Pos, dystrophin C‐terminal positive; PP, musculus palatopharyngeus; UV, musculus uvula.
