The aim of present study was to evaluate the effects of immunophilin ligands (cyclosporin A, FK506 and rapamycin) on the simulated ischemia-induced release of pro-inflammatory cytokines (IL-1beta, TNF-alpha and IL-2) in rat primary astrocyte cell cultures. Astrocytes were exposed to cyclosporin A (CsA) (0.25, 0.5, 1, 10, 20 and 50 microM), FK506 (1, 10, 100, 1000 nM) and rapamycin (10, 100, 500 and 1000 nM). In vitro simulated ischemia significantly increased secretion of IL-1beta, TNF-alpha and IL-2 by astrocyte cultures deprived of microglia (by
shaking
and incubating with L-leucine methyl ester). CsA (at concentrations of 10-50 microM), FK506 (at all used concentrations) and rapamycin (in dose-dependent manner) significantly attenuated IL-1beta release after 24 h exposure to ischemic conditions. Immunophilin ligands at all used concentrations significantly decreased TNF-alpha levels in culture media after 24 h exposure to ischemia. Moreover, significant decrease in IL-2 secretion at 0.25, 0.5, 1 and 50 microM CsA and FK506 at concentrations of 100 and 1000 nM were observed. The results suggest that immunophilin ligands may regulate glial activity during ischemia by affecting the release of pro-inflammatory cytokines.

Parkinson syndrome occurs in the course of chemical intoxication, especially Mn, CS2, CO. It is rarely caused by chronic mercury intoxication. We present the case of 55 year old man who was exposed to metallic mercury vapor during 33 years of working in the chemical plant at the production of chlorine. On several occassions patient was removed from contact with Hg because of the symptoms of increased Hg absorption. At the age of 52 he developed hand
tremor
, balance and gait disturbance with bradykinesia, paresthesias of the upper extremities, neurobehavioral abnormalities, slight memory loss, and spatial disorientation. Psychoneurological examination revealed dementia, Parkinson's syndrome and ataxia of the lower limbs. Mercury excretion in the urine, which equaled 18.3 mu\g creatinine, confirmed exposure to Hg. MRI of the head revealed cortical and cerebellar atrophy. Electroneurography examination found features of subclinical peripheral sensory axonopathy of the upper limbs. Despite atypical clinical course (parkinsonismus) chronic mercury encephalopathy was diagnosed based on documented occupational exposure and diagnostic test results.

The irregular rhythm, presence at rest and acceleration during posture and active movements, low frequency and focal signs are its main features. A case of 49 years old male with
tremor
of left arm lasting five years is reported. The patient has been suffering from rheumatoid arthritis from 1987.8 years ago a chronic lymphoblasic leukemia was revealed. In upper left arm irregular rest, postural and kinetic
tremor
occurs, with increasing amplitude and frequency 3.5 Hz. Physical examination revealed pyramidal syndrome and deliberative symptoms. MRI showed vasculitis-like subcortical changes and leukoarajosis-like signs. Neuropsychological examination indicates slight impairment of cognitive functions. Treatment with benzodiazepins and L-dopa was ineffective. Described above symptoms fulfill Holmes'
tremor
criteria. Only few studies confirmed correlation between
tremor
and presence of autoimmune diseases. Our case is the first study describing Holmes'
tremor
, which occurred during rheumatoid arthritis or chronic lymphoblastic leukemia.

The aim of the study was to check whether VEP in Parkinson disease are pathological and if there is a relationship between VEP studies and severity, duration of the disease. The authors recruited 54 patient with idiopathic Parkinson disease with significant differences in laterality of bradykinesia, rigidity and
tremor
. The examined group consisted of 25 males and 29 females, aged from 34 to 82 years; mean age 70.47; the disease duration--from 3 month to 20 years; mean duration 7.76. The asymmetry of extra-pyramidal symptoms, severity of disease with UPDRS and activities of daily living with Schwabach and England were evaluated. Age, disease duration, treatment duration, current dose and side effects of levodopa were taken into account. Neurological examination and VEP were performed before the morning dose of levodopa U-test and Spearman correlation were used for statistical analysis. The VEP latencies were found in 11 patients (15.94%). Mean VEP latency for the right eye in this group was 116.83 (range: 122.3-111.0) and 120.45 (range: 161.5-111.0) for the left. In the group of patients with normal VEP the results were respectively 99.91 and 100.39. There were no significant correlations between the VEP and the asymmetry of neurological symptoms, disease severity and duration, treatment duration, the dose and side effects of Levodopa. There was a significant relationship between VEP latency and patients age and activities of daily living.

Vascular parkinsonism has not been well defined and the clinical correlation of vascular parkinsonism is still not clear. The aim of the study was to estimate prevalence of occurrence of vascular parkinsonism, analysis of risk factors leading to its development and to identify clinical features that suggest a vascular origin. 214 patients with Parkinson's disease were examined. Their ages ranged from 37 to 88 years (median 66.4 years). Evidence of vascular parkinsonism was assessed using a vascular rating scale previously described by Winikates and Jankovic. Statistical analysis was performed with Mann-Whitney U test, chi 2 Pearson test, chi 2 Yates test, Spearman rank correlation and Student's t test. Out of 214 patients 8 were proved to have developed Parkinson's disease due to vascular disease, what gave 3.74%. Out of risk factors for stroke 5 patients had hypertension, 3 had diabetes mellitus, 2 suffered from heart disease, 2 had infarctus myocardii, 1 had hyperlipidemia, 1 had atrial fibrillation. Additionally, those patients had neuroimaging (CT or MRI) evidence of vascular disease in one or more vascular territories. Patients with vascular parkinsonism were older, had shorter duration of disease, were more likely to present rigidity rather than
tremor
. Dementia and incontinence were more common in vascular group than in Parkinson's disease group. Patients with vascular parkinsonism were also significantly more likely to have corticospinal findings. Proving that Parkinson's disease had vascular etiology is extremely difficult. The test results are inconclusive.

The aim of the study was to evaluate the frequency of depression in patients with Parkinson's disease. The authors recruited 85 patients with idiopathic Parkinson's disease, 42 males and 43 females aged 34-82 years (mean age 68.7). Age at onset ranged 24-79 (mean 60.9 years). Disease duration ranged from 3 month to 20 years (mean 7.86 years). In 62 patients (72.94%) mixed type of the disease was diagnosed, in 14 (16.47%)
tremor
and in 9 (10.59%) rigidity predominated. UPDRS was used to evaluate the severity of the disease (results ranged 28-90, mean 51.4). Activity of daily living was estimated according to Schwab and England Scale (range 40-90, mean 68.1). Depression was evaluated with Hamilton, Beck and Montgomery-Asberg scales. The results were analysed with Spearman correlation. Depression was diagnosed in 53 (62.35%) patients [in 7 (8.24%) light; in 14 (16.47%) middle; in 19 (22.35%) heavy; in 13 (15.29%) very heavy]. The results acquired with all three scales were not statistically different. There were significant positive correlations between depression and female sex, severity of the disease, dyskinesia as side effect of.

Many patients with Parkinson's disease (PD) suffer from severe bilateral appendicular off (bradykinesia, rigidity,
tremor
) and on (dyskinesia, dystonia) symptoms. After unilateral pallidotomy several of these patients still suffer from severe bradykinesia, rigidity, or dyskinesia of the ipsilateral side. In addition such symptoms as walking difficulty, freezing, trunk, neck, or facial dyskinesia are not significantly alleviated after unilateral pallidotomy. These patients seem to be good candidates for bilateral staged pallidotomy. The aim of this study is to evaluate the motor symptoms after staged bilateral pallidotomy in advanced PD patients. 34 patients were studied. The patients were assessed using UPDRS version 3, Hoehn and Yahr scale, Schwab and England scale before and up to 24 months after surgery in off and on state. In off drug state, the total motor score of the UPDRS compared to preoperative off drug state was improved by 61% at 24 months of follow-up. All cardinal features of PD improved significantly in postoperative drug off state compared to drug off state before bilateral pallidotomy--parkinsonian
tremor
(items 20-21) by 62%, rigidity (item 22 UPDRS) by 81% and bradykinesia (items 23-26) by 67%. Also gait including falling, freezing, walking (items 13-14-15 UPDRS) and gait and postural stability (items 29-30 UPDRS) showed good improvement by 69% with bilateral pallidotomy in off drug phases. There was minimal improvement in motor score of UPDRS in on state. Duration of dyskinesia and severity of dyskinesia (items 32-33 UPDRS) showed dramatic improvement after bilateral pallidotomy. Bilateral pallidotomy affords impressive elimination of all appendicular and truncal dyskinesias, dystonias, and generally improved all symptoms in off state.

Because all machines and vibration devices also produce noise, the combined activities of both factors are usually examined together. The opinion dominates that vibration exerts only a weak, additionally traumatic influence on the hearing organ. The aim of our investigation was to determine the influence of long-term, whole-body vibration on the incudo-stapedial joint which integrity is indispensable for the protection of the inner ear from the effect of noise. To realize the experimental conditions, sinusoidal vertical
shaking
(10 Hz, 5 mm, 1.4 g rms), an own noiseless apparatus was consisted. The experiment was carried out on 30 young, healthy, colored guinea pigs. They were subjected to vibration over 1, 3, and 6 months (132, 396, and 792 hours). The investigation was based on examination of the structures of the incudo-stapedial joint in the scanning electron microscopy. Among experimental animals two kinds of changes were ascertained which can be attributed to the activity of vibration. One was an extensive damage to the surfaces of the incudo-stapedial joint itself. The other was an often observed thickening of the bursa of the joint. The frequencies of occurrence and stages of advancement of both were in direct relationship to the duration of the experiment. The evaluation of the observed changes permits an explanation of the mechanism of the damage to hearing of persons subjected to noise and vibration. Whole-body vibration damages the incudo-stapedial joint, making its separation difficult. This may, than, facilitate the transfer of noise and its injurious influence to the inner ear.

Carriers of premutation within the FMR1 gene are typically normal intellectually, although a limited number of them have been reported to have either learning disabilities or mild dysmorphic features. A neurological condition involving intention tremor, ataxia and cognitive decline has recently been identified among older males carrying premutation alleles of the FMR1 gene, including grandfathers of children affected with fragile X syndrome. Characteristic findings from magnetic resonance imaging include cerebral and cerebellar volume loss and altered signal intensities of the middle cerebellar peduncles. This syndrome may represent one of the more common causes of
tremor
, ataxia and dementia among older males. The diagnosis of FXTAS is straightforward if a family at high genetic risk could be identified. Thus genetic counseling should be offered to such family.

The term of isolation of arylosulfonic acids as hydrolysing factors from casein's hydrolyzates have been worked out. The most satisfactory results have been achieved when using in this case chloride 2,3,5-triphenylo-2H-tetrazole. When using benzenosulfonic acid as the best hydrolising factor 98.4% of this acid was removed from hydrolysates of hoofs whereas 96.1% was removed from hydrolysates of bristles. The residues of acids remaining in hydrolysates have been removed by
shaking
with Wofatyt SBW in form H+. The total recovery of aminoacids irrespectively to kind of hydrolyzate and applied acid amounts to 95.5% average.
