Aspects of metabolic changes in first-episode drug-naïve schizophrenic patients.

Unlabelled: Aim The aim of the study was to investigate the state of parameters characterising different sites of metabolism and the degree of endogenous intoxication in first-episode drug-naïve schizophrenic [first episode of schizophrenia (FES)] patients. It is hypothesised that the FES is the initial step in the development of pathologically disturbed biochemical status that is characteristic of chronic schizophrenia.

Methods: Platelet monoamine oxidase (MAO) and serum semicarbazide-sensitive amine oxidase (SSAO) activities, serum concentrations of middle-mass endotoxic molecules (MMEM) and malondialdehyde and parameters of the serum albumin functional state were measured in 26 FES patients and 15 age-matched healthy controls.

Change in platelet monoamine oxidase activity in the acutest period of ischemic stroke is associated with the degree of neurological recovery.

We studied monoamine oxidase activity (MAO) in platelets of patients in the acute period of ischemic stroke. Neurological deficit was evaluated by the data of clinical examinations and scales. In 80% patients MAO activity was considerably increased on 3-5 day after stroke.

[Clinical significance of humoral compensatory reactions in the acute period of ischemic stroke].

To determine the clinical significance of humoral nonspecific reactions in the acute period of ischemic hemispheric stroke (IS), some biochemical and biophysical parameters have been studied in 30 patients (mean age 67±10 years). Platelet monoaminooxidase (MAO) activity, levels of middle-sized molecules (MM), malonic dialdehyde (MDA) and parameters of the functional state of serum albumin (the effective concentration and binding reserve of albumin) have been measured. Severity of neurological deficit and functional recovery of patients with IS was assessed with the NIHSS and the Barthel index.

[Role of semicarbazide-sensitive amine oxidase in disturbances of endogenic detoxication in ischemic stroke patients].

Oxidative stress is a pathogenetic factor of ischemic stroke. Enhancement in the activity of one of xenobiotic transformation enzymes and biogenic amines (serum semicarbazide-sensitive amine oxidase (SSAO)) leads to the higher production of secondary toxins stimulating oxidative stress. We studied 38 patients (mean age 69,5 +/- 7,2 years) in the early restoration period of ischemic stroke.

[Endogenous intoxication and compensatory reactions in the restoration period of ischemic stroke].

An aim of the study was to assess the severity of the syndrome of nonspecific metabolic endogenous intoxication (EI) and characteristics of compensatory reaction of serum albumin (SA) in patients in the early restoration period (4-5 months) of ischemic stroke (II). We measured levels of middle-sized molecules (MSM) and malonic dialdehyde (MDA) and determined parameters of functional activity of SA in 30 patients (mean age 69 +/- 8 years) after the first II and in 17 age- and sex-matched healthy people. Neurological deficit and functional restoration of patients were assessed with the NIHSS and Barthel index.
