[Dynamics of activity of neurokinine receptors and enzymes of intercellular matrix (MMP9 and TIMP-2) in the nasal mucosa of the chronic cigarette smokers].

The present study was designed to determine localization of substance P and neuroknine receptors in the nasal mucous membrane of the subjects having the history of chronic smoking. The mechanisms underlying reorganization of the mucous tissue were elucidated by measuring the activity of intercellular matrix enzymes (MMP9 and TIMP-2). The activity of neurokinine receptors localized on the cells of ciliary epithelium and in the connective tissue elements of the submucous structures was shown to be significantly increased.

[Pathophysiological mechanisms of hemorrhagic stroke and the ways of differential therapy].

The changes developing in the perifocal area of hematoma and perspectives of antioxidant and chelate therapy were studied on the model of experimental hemorrhagic stroke and in clinical conditions. Microcirculatory, ischemic and inflammation disturbances with a certain time sequence were found in the perifocal areas. These changes, along with hypostasis and oxidative stress, form the pathobiochemical cascade of changes in hemorrhagic stroke and are potential therapeutic targets.

[Induction of NO-synthase and glial fibrillary acidic protein in astrocytes of the temporal cortex in rats with audiogenic epileptiform reaction].

The localization of NADPH-diaphorase (NADPH-d), inducible NO-synthase (iNOS) and glial fibrillary acidic protein (GFAP) was studied in the astrocytes of the temporal cortex in rats of Krushinsky-Molodkina strain which are genetically prone to audiogenic seizures. The seizure was evoked by thrice-repeated acoustic stimulation. Wistar rats and acoustically untreated seizure-free Krushinsky-Molodkina rats were used as a control.

[Structure and neurochemistry of the raphe nuclei in teleosts].

NO is an important modulator of the brain serotoninergic function as it is co-localized with 5-hydroxytryptamine in the neurons of raphe nuclei in the brain of all the higher vertebrates. In the brain of fishes this property of NO is poorly studied. The purpose of this work was to study the neuromorphological peculiarities and distribution of NO-ergic neurons in raphe nuclei of Teleost species--carps and perch-like fishes.

[NO-ergic rat brain commissural neurons in the norm and during opiate administration].

Using histochemical reaction demonstrating NADPH-diaphorase (NADPH-d), the dynamics of NO synthesis was studied in the rat brain raphe nuclei following intravenous injection of morphine hydrochloride. In normal conditions NADPH-d activity was demonstrated in neurons of all raphe nuclei. Acute and chronic administration of morphine in different doses (0.
