[Neurotransmitter changes in the rat brain under combined intoxication induced by alcohol and morphine].

We investigated the levels of biogenic monoamines and their metabolites in the rat hypothalamus, midbrain and cerebellum in acute complex intoxication with morphine and alcohol. The distinctive features of neurotransmitter disorders in various parts of the rat brain under a single exposure to ethanol and morphine, as well as the differences between acute morphine-alcohol and alcohol-morphine intoxication were established. Complex intoxication with alcohol and morphine resulted in signs of dopamine consumption only in the hypothalamus, regardless of the order of alcohol and morphine administration.

Peroxisome Proliferator-Activated Receptor-δ Deficiency in Microglia Results in Exacerbated Axonal Injury and Tissue Loss in Experimental Autoimmune Encephalomyelitis.

Peroxisome proliferator-activated receptor (PPAR)-δ is a nuclear receptor that functions to maintain metabolic homeostasis, regulate cell growth, and limit the development of excessive inflammation during immune responses. Previously, we reported that PPAR-δ-deficient mice develop a more severe clinical course of experimental autoimmune encephalomyelitis (EAE); however, it was difficult to delineate the role that microglia played in this disease phenotype since PPAR-δ-deficient mice exhibited a number of immune defects that enhanced CNS inflammation upstream of microglia activation. Here, we specifically investigated the role of PPAR-δ in microglia during EAE by using mice where excision of a floxed allele was driven by expression of a tamoxifen (TAM)-inducible CX3C chemokine receptor 1 promoter-Cre recombinase transgene (: ).

Peroxisome Proliferator-Activated Receptor-δ Acts within Peripheral Myeloid Cells to Limit Th Cell Priming during Experimental Autoimmune Encephalomyelitis.

Peroxisome proliferator-activated receptor (PPAR)-δ is a fatty acid-activated transcription factor that regulates metabolic homeostasis, cell growth, and differentiation. Previously, we reported that mice with a global deficiency of PPAR-δ develop an exacerbated course of experimental autoimmune encephalomyelitis (EAE), highlighting a role for this nuclear receptor in limiting the development of CNS inflammation. However, the cell-specific contribution of PPAR-δ to the more severe CNS inflammatory response remained unclear.

Impact of Steroids on the Inflammatory Response after Ischemic Acute Kidney Injury in Rats.

Inflammation plays a crucial role in acute kidney injury (AKI). The current study was designed to analyze the influence of prednisolone treatment on the inflammatory reaction during the first 96 h after AKI induction in a rat model. AKI was induced by unilateral clipping of the renal vessels.

[HOMOCYSTEINE AS A PROGNOSTIC MARKER OF ATRIAL REMODELING AND CLINICAL PICTURE IN PATIENTS WITH PAROXYSMAL AND PERSISTENT FORMS OF ATRIAL FIBRILLATION].

The aim of this work was to study prognostic significance of the relationship between the homocysteine level, structural/functional atrial remodeling, and clinical picture of paroxysmal and persistent forms of atrial fibrillation (AF). The study included 75 patients with AF concomitant with coronary heart disease and hypertensive disease without apparent structural changes in myocardium. Group 1 was comprised of 48 patients with paroxysmal AF, group 2 of 27 patients with persistent AF.
