The Beneficial Impact of the Black Chokeberry Extract against the Oxidative Stress in the Sublingual Salivary Gland of Rats Intoxicated with Cadmium

Table 6

Mutual relationships (Pearson’s correlation analysis) between the investigated markers of the oxidative/antioxidative balance and oxidative stress of the sublingual salivary gland, as well as between these parameters and cadmium (Cd) concentration and content in the salivary glands of female rats¹.
