Duration:Five months

Background:There are some anatomical, functional and hormonal changes that appear with aging. Among them are decreases in the activity of the Pituitary; which contributes to a decrease in the liver's production of Somatomedin-C; therefore, an increase in excess fat and a decrease in lean body mass.

Materials and Methods: 21 healthy adult subjects with known growth hormone deficiencies of both sexes between the ages of 45 and 86 years old were studied. Subjects were randomly assigned to one of three different groups.

At the beginning of the study, a clinical history of all patients was performed and blood samples were taken for blood chemistry studies which included: blood glucose, urea, creatinine and uric acid; lipids profile: total cholesterol, cholesterol HDL, cholesterol LDL, and triglycerides.
