Definitions

  • the present invention relates to a pharmaceutical composition for treating Parkinson's disease and inhibiting levodopa side effects and a health functional food comprising melanin concentrating hormone as an active ingredient.
  • Parkinson's disease is characterized by neurodegeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc), which gradually leads to depletion of dopamine in the striatum. Parkinson's disease breaks down the balance of the basal ganglia and impairs the function of motor neurons, causing rigidity, tremor, and ainesia. One to five percent of people over 50 are the second most common neurodegenerative diseases.
  • Parkinson's disease The ultimate cause of Parkinson's disease is unknown, but several symptoms appear to be due to a deficiency of dopamine, a neurotransmitter in the brain made from nerve cells in the substantia nigra area of the normal brain. .
  • Dopamine produced by neurons distributed in the black matter of the brain is linked to the basal ganglia of the brain, including the corpus striatum.
  • the basal ganglia are intricately linked to the motor cortex and many other areas of the brain, making it an important part of the body's movements, allowing them to perform smooth, harmonious and accurate movements.
  • Dopamine deficiency which is free from the end of basal ganglia dopaminergic nerves caused by such dopaminergic nerve damage, is a major cause of motility disorders in Parkinson's disease.
  • Parkinson's disease namely, the destruction of the neural cells of the black matter, but active research is being conducted to find out.

MPTP reduces dopamine neurons in humans and nonhuman primates, causes astrocytes and activates microglia in cerebrospinal densities rather than specifically targeting dopaminergic neurons associated with Parkinson's disease (Nat Med, 1999, 5). (12), 1403-1409), causing typical biochemical or pathological symptoms of Parkinson's disease (Neurosci, 2000, 16 (2), 135-142).

  • levodopa causes side effects such as hallucination, insomnia, nausea and dyskinesia.
  • levodopa-induced dyskinesia LID is the most serious side effect in patients with Parkinson's disease who are chronically using levodopa.
  • Anticholinergic drugs may show autonomic nervous system abnormalities or mental function abnormalities, and thus they are limited to continuous administration to older patients.
