Levodopa 0-8 growth hormone 1 Homo sapiens 54-68 21543973-4 2011 Levodopa may experimentally exert supportive effects on nerve growth factor synthesis and on growth hormone production, a hormonal compound with regenerative potential. Levodopa 0-8 growth hormone 1 Homo sapiens 93-107 21543973-5 2011 OBJECTIVE: The objective of this study was to investigate the effects of soluble 250-mg levodopa/benserazide administration on plasma occurrence of levodopa, nerve growth factor, and growth hormone in patients with Parkinson disease over an interval of 60 minutes. Levodopa 88-96 growth hormone 1 Homo sapiens 183-197 21543973-6 2011 RESULTS: Levodopa moderately increased bioavailability of nerve growth factor and growth hormone combined with the rise of levodopa. Levodopa 9-17 growth hormone 1 Homo sapiens 82-96 21543973-8 2011 CONCLUSIONS: Axonal degeneration may not be due to levodopa itself, as levodopa supports production of nerve growth factor and of growth hormone. Levodopa 71-79 growth hormone 1 Homo sapiens 130-144
