[Plasma lipoprotein absorption by steroid-producing organs in the rat].

A study was made of the blood plasma iodinated lipoprotein (LP) absorption by the organs and tissues of rats following i.v. injection. The adrenals and ovaries were shown to effectively absorb high density lipoproteins (HDL) as compared to the liver, spleen, kidneys, heart and lungs. HDL absorption reached its maximum 30 min after LP injection. Six hours later the adrenal tissue radioactivity level decreased by 30% and after 12 h 3-fold. The time-course of HDL absorption by the ovaries was characterized by a slow increase in radioactivity after 6 h and a gradual decrease of the label index after 12 h. Differences in HDL absorption by the adrenals and ovaries reflected some functional features of these steroid producing organs.
