Table 1. Morphometric parameters of islets cell mitochondria.

Measurements
PP	Number of points on mitochondria per number of test points
LL	Number of intersections of mitochondria per unit length of test line
NA	Number of interceptions of mitochondria per unit test area

Primary parameters
VVM	mm3/mm3	Volume of mitochondria per unit β-cell volume (volume density)
SVM	mm2/mm3	Outer surface area of mitochondria per unit β-cell volume (density of outer surface area)
NVM	1/mm3	Number of mitochondria per unit β-cell volume (numerical density)

Secondary parameters
VVM/NVM	mm3	Average mitochondrial volume
SVM/NVM	mm2	Average mitochondrial outer surface area
SVM/VVM	mm2/mm3	Mitochondrial outer surface area per unit mitochondrial volume
