Growth hormone and epidermal growth factor in salivary glands of giant and dwarf transgenic mice.

Epidermal growth factor (EGF) in rat salivary glands is regulated by testosterone, thyroxin, and growth hormone (GH). Salivary glands of 45-day-old giant and dwarf male and female transgenic mice were examined histologically and by immunohistochemistry (IHC) for EGF. Male giants showed no significant differences from wild-type (WT) parotid and submandibular glands.

Influence of growth hormone on the mandibular condylar cartilage of rats.

Unlabelled: Growth hormone (GH) stimulates mandibular growth but its effect on the mandibular condylar cartilage is not well understood.

Objective: This study was designed to understand the influence of GH on mitotic activity and on chondrocytes maturation. The effect of GH on cartilage thickness was also determined.
