  The use of orally administered L-arginine in conjunction with a topical preparation for producing enhanced blood flow in tissue thus causing beneficial effects such as warming cold tissue of the hands and feet, promoting hair growth on bald scalp tissue, promoting healing of superficial ulcers such as leg ulcers in persons with diabetes, and overcoming male erectile failure (impotence) is disclosed. Specifically, use of orally administered L-arginine in conjunction with this is topical preparation provides local delivery of the amino acid L-arginine, an important biological precursor to the main substance which is responsible for relaxation of blood vessels permitting enhancement of blood flow. In the preferred embodiments, the L-arginine is provided so that it can be topically applied to the cold tissue. The preparation also contains an agent which aids in the transfer of L-arginine into the tissue. In the preferred embodiments this agent overcomes the resistance to transfer caused by the high charge density of L-arginine. In the preferred embodiments this means is high ionic strength created by addition of sodium chloride. This preparation, when topically applied to cold tissue, warming begins within 10 to 45 minutes and is sustained for periods as long as 2 to 18 hours. Further this preparation when applied nightly to bald scalp tissue for a period of time causes substantial growth of hair on the bald scalp, causes the healing of superficial ulcers such as leg ulcers and overcomes impotence.

  本发明公开了口服 L-精氨酸与外用制剂配合使用的方法，口服 L-精氨酸与外用制剂配合使用可增强组织中的血流量，从而产生有益的效果，如温暖手脚冰冷的组织、促进秃头组织的毛发生长、促进浅表溃疡（如糖尿病患者的腿部溃疡）愈合以及克服男性勃起功能障碍（阳痿）。具体来说，将口服 L-精氨酸与本局部制剂结合使用，可在局部提供氨基酸 L-精氨酸，这是一种重要的生物前体物质，其主要作用是松弛血管，促进血液流动。在优选的实施方案中，提供的 L-精氨酸可局部应用于冷组织。制剂中还含有一种有助于将 L-精氨酸转移到组织中的制剂。在优选的实施方案中，这种制剂可以克服 L-精氨酸的高电荷密度所造成的转移阻力。在优选的实施方案中，这种手段是通过添加氯化钠产生高离子强度。这种制剂局部用于冷组织时，可在 10 至 45 分钟内开始升温，持续时间长达 2 至 18 小时。此外，这种制剂每晚涂抹在秃头组织上一段时间后，可使秃头上的头发大量生长，使浅表溃疡（如腿部溃疡）愈合，并克服阳痿。
