RESUMEN
To explore the relationship between the clinical manifestations and functional magnetic resonance images [MRI] of delayed encephalopathy after carbon monoxide intoxication. Six patients received the MRI were diagnosed with delayed encephalopathy after carbon monoxide [CO] poisoning. Clinical manifestations were observed in each patient. MRI revealed multiple lesions. The majority of the lesions were located in the globus pallidus, sub cortical white matter, and basal ganglia. The cognitive injury, akinetic mutism, fecal and uroclepsia, forced crying, forced laughing and extra pyramidal syndromes such as chorea and parkinsonism were manifested in clinic. Cognitive impairment improved greatly while involuntary movements only improved slightly after several months. Meanwhile brain MRI suggested remarkable improvement. Neuroimaging directly correlated with the clinical manifestations
RESUMEN
Objective:To study the chemical constituents in the roots of Aconitum transsectum. Methods:The compounds were i-solated and purified by column chromatography on the columns of silica gel, Al2 O3 and Sephadex LH-20, and their structures were elu-cidated on the basis of spectroscopic evidence ( MS and NMR) . Results:Totally 12 compounds were isolated from A. transsectum, and characterized as yunaconitine (1), indaconitine (2), crassialine A (3), 8-deacetylyunaconitine (4), talatisamine (5), chasma-conitine (6), 14-acetyltalatisamine (7), vilmoraconitine (8), sachaconitine (9), 14-acetylsachaconitine (10), acoforestinine (11) and vilmorrianine C (12). Conclusion:Compounds 8-11 are obtained from A. transsectum for the first time.
