Severe systemic responses including neurologic complications such as myasthenia gravis, myeloradiculopathy, optic neuropathy, parkinsonism, stroke and Guillain-$barr{\acute{e}}$ syndrome can occur after bee stings. This case describes a 78-year-old female who presented with symptoms of acute progressive bilateral symmetrical weakness in both lower legs after multiple bee stings. Nerve conduction study findings were consistent with acute sensorimotor axonal neuropathy and recovered by treatment with intravenous immunoglobulin. This case highlights that bee stings can result in acute onset Guillain-$barr{\acute{e}}$ syndrome, although the pathophysiologies of bee venoms need to be investigated accurately.

Human DJ-1 and Escherichia coli Hsp31 belong to ThiJ/PfpI family whose members contain a conserved domain. DJ-1 is associated with autosomal recessive early-onset parkinsonism and Hsp31 is a molecular chaperone. Structural comparisons between DJ-1, Hsp31, and an archeal protease, a member of ThiJ/PfpI family, lead to the identification of the chaperons activity of DJ-1 and the proteolytic activity of Hsp31. Moreover, the comparisons provide insights into how the functional diversity is realized in proteins that share an evolutionarily conserved domain. On the basis of the chaperons activity, the possible role of DJ-1 in the pathogenesis of Parkinson's disease is discussed.

Neuroleptic malignant syndrome is a serious complication of levodopa withdrawal in patients with Parkinson's disease. We report a patient with advanced parkinsonism who developed neuroleptic malignant syndrome in setting of withdrawal of levodopa intake.

Parkinson's disease is a common neurodegenerative disorder that is mainly caused by dopaminergic neuron loss in the substantia nigra. Several radiopharmaceutics have been developed to evaluate the integrity of dopaminergic neuronal system. In vivo PET and SPECT imaging of presynaptic dopamine imaing are already applied to Parkinson's disease and other parkinsonism, and can demonstrate the dopaminergic dysfunction. This review summarized the use of the presynaptic dopaminergic imaging in PD as biomarkers in evaluation of disease progression as well as in diagnosis of PD.

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a well-known dopamine neuron-specific toxin. But the involvement of oxidative damage in the pathogenesis of MPTP-induced parkinsonism is still uncertain. In this study, by using 2',7',-dichlorofluorescin diacetate(DCFH-DA) that detects intracellular oxidative processes, the effect of MPTP on dichlorofluorescein fluorescence in dissociated cells from fetal rat mesencephalon in culture was investigated. At 7th day in culture, cells were loaded with DCFH-DA, and exposed to 1 mM MPTP or MPP+. MPTP induced dichlorofluorescein-fluorescence which was peaked at 3 min and mostly faded away 30 min after MPTP treatment.

The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicity may playa role in the degeneration of substantia nigra, which is the major focus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested.(omitted)

Parkinson's syndrome is a degenerative brain disease that presents characteristic motor symptoms of tremor, rigidity, and gait disturbance. In addition to these motor symptoms, Parkinson's syndrome also presents non-motor symptoms (NMSs) such as sleep disturbance and cognitive decline. NMSs reduce patient's quality of life and psychosocial functioning and cause economic burden on the patient, so appropriate evaluation and treatment are required. Lewy body dementia is one of the several diseases belonging to Parkinson's syndrome. Its symptoms such as cognitive function, memory impairment, and hallucinations occur with Parkinsonism. Although drug therapy is being used with drug treatment to treat non-motor symptoms, it has limitations such as side effects, which stimulated interest in other complementary treatment methods such as oriental medicine treatment, dance, and yoga. The patient in this case complained of tremor in the right upper extremity, muscle hypertension and pain, and persistent vision, memory, and cognitive decline. The patient was diagnosed with probable Lewy body dementia. The patient was hospitalized for 4 months and received acupuncture and herbal medicines. After treatment, the patient's NMS scale scores decreased from 90 to 63, and the Unified Parkinson's Disease Rating Scale scores (summed I, II, and III) decreased from 17 points to 8 points. The Beck Depression Inventory score decreased from 22 points to 13 points. In addition, the patient's subjective evaluation revealed improvement. In this case, a patient diagnosed with probable Lewy body dementia who did not respond to the standard treatment and did not want to take medications showed improvement in not only motor symptoms but also NMSs after integrative Korean medicine treatment.

Multiple system atrophy is a neurodegenerative disease that causes diverse bodily dysfunctions (cerebellar, pyramidal, automatic, and urological, in any combination), as well as Parkinsonism. Patients with multiple system atrophy commonly display antecollis, a condition where the patient's head tilts forward more than 45 degrees. Despite its common occurrence in these patients, no current standardized therapies are effective for treating antecollis. In this study, Korean medicinal treatments, including Chuna manual therapy, pharmaco-acupuncture, bee venom acupuncture, acupuncture, herbal medicine, and moxibustion therapy, were administered to the patient over a 27-day period. After the treatment, assessments of the head position on the EPIS-PD scale (Part I) and at a standing position from the side (Part II) both revealed improvements. As the head flexion angle decreased, the patient's head posture improved, as determined by a decrease in angle from 80 degrees to 30 degrees in the upright, standing position. As a result, patients who previously were unable to walk without the support of walking frames could now roam freely and independently, with significant increases in both walking speed and distance. In essence, this study suggests that Korean medicine is an effective treatment for patients with multiple system atrophy who suffer from antecollis and gait disorders.
