AB  - The diagnosis of amyotrophic lateral sclerosis (ALS) based on ALS functional rating scale-revised (ALSFRS-R) scores is often shown be unreliable and false. On the other hand, magnetic resonance imaging (MRI) studies of a brain of ALS patients showed the presence of iron deposits in the precentral gyruses of gray matter (PGGM) and also the potential leakage of iron to cerebro-spinal fluid (CSF) through compromised blood-brain barrier. The aim of this study was to determine if there is a specific feature in CSF that distinguishes patients with ALS from the control subjects. CSF obtained from ALS patients and normal controls were analyzed using the technique of cyclic voltammetry. The results show that at the potential of 1.1 – 1.2 V vs. Ag/AgCl electrode, the plateau appeared and the potential of oxygen evolution with shifted toward more positive values from the ALS patients. These voltammogram features were not present for the control patients showing this technique to be promising candidate for evaluating new biomarkers for ALS.

AB  - The diagnosis of amyotrophic lateral sclerosis (ALS) based on ALS functional rating score (ALSFRS) is often shown to be unreliable and false. On the other hand, it is a fact that MRI studies of a brain of ALS patients showthe presence of iron deposits in precentral gyruses of gray matter (PGGM), meaning that blood-brain barrier is compromised. Therefore, various studies have been performed with the goal to detect excess of iron in the cerebrospinal fluid (CSF) of ALS patients (e.g. EPR detection of •OH radicals as products of Fenton reaction after supplementation of H2O2 to the CSF). Unfortunately, no acceptable correlation could emerge, probably caused by the presence of a range of iron complexes in CSF. Therefore, a different approach to detect iron states in CFS is required. The aim of thisworkwas to determine if there is a specific feature in CSF that distinguishes patients with ALS from those with purely motor peripheral neuropathy (PN) and healthy control subjects. CSF obtained from ALS patients and normal controls were analyzed using the technique of cyclic voltammetry. The results show that, at potential of 1.1 - 1.2 V vs. Ag/AgCl electrode, for the ALS patients, the plateau appeared and the potential of oxygen evolutionwas shifted toward more positive values. These voltammogram features were not present for the control patients. The cyclic voltammetry is fast and inexpensive technique and showed to be promising candidate for evaluating new biomarkers for ALS.

AB  - A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic acid bleaching, lipid peroxidation by Fenton reaction, EPR spin-probing assay using stable nitroxide radicals, DPPH., and ABTS(.+) scavenging assays. Reaction mechanism of the volatile oil components with nitroxide radicals, based on IR spectra analysis, is proposed. AUVO demonstrated poor scavenging ability against DPPH, and ABTS(.+) comparing to synthetic antioxidants BHT and trolox, while in beta-carotene-linoleic acid system AUVO showed an effect comparable to those for BHT. AUVO was also capable to scavenge stable nitroxide radicals such as water-soluble Tempone, and 7-DS and 12-DS, incorporated into the liposome membrane. Finally, AUVO increased membrane fluidity, which could be an important feature for further in vivo investigation of some disorders, such as hypertension and atherosclerosis.
