Abstract: A portable, lightweight medical radiographic device having an articulated support is described. The device includes a base, an elongated supporting structure having multiple sections interconnected by adjustable joints, a mount for a radiological camera, and a support for a film cartridge. The camera mount includes a concave, motorized track; the film cartridge support is also concave and may also provide motorized film advancement. A selected human body part to be imaged may be placed between the camera mount and the film track. When the camera, motorized track, and film support are energized, coordinated movement of the camera relative to the film results in a panoramic image of the body part on the exposed film.

Abstract: The disclosed invention provides methods and compositions ulilizing L-.alpha.-amino acids for enhancing the rate of penetration through the skin of both topical medicaments and of drugs employed for systemic administration. Fifteen L-.alpha.-amino acids were tested and found to enhance the rate of penetration of levonorgestrel through hairless mouse skin. These were Tryptophan, Glutamic Acid, Glycine, Proline, Alanine, Serine, Arginine, Aspartic Acid, Leucine, Isoleucine, Cysteine, Valine, .alpha.-Aminobutyric Acid, Norvaline and Norleucine. The effect of pH on the rate of penetration of the various amino acids was also examined and found to be unpredictable overall.
