    <description>Title: Neurobiologia somnului
Authors: Chiriac, Ecaterina
Abstract: The humoral theory of sleep regulation proposed by Ishimori and Pieron postulates that&#xD;
the homeostatic sleep drive leads to the accumulation of somnogens during wakefulness, and that&#xD;
this homeostatic need is discharged during sleep. Prostaglandin D2, adenosine, and cytokines&#xD;
have been proposed as effective sleep substances. Also, several interactions between sleep- and&#xD;
wake-active neurons have been proposed at the systems level in many models of sleep–wake&#xD;
regulation. In this review, we describe briefly the neurobiology of sleep.&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
Teoria umorală a reglării somnului propusă de Ishimori şi Pieron postulează că în timpul&#xD;
stării de veghe în organism se acumulează substanţe somnogene, care asigură homeostaza&#xD;
somnului. Prostaglandina D2, adenozina şi citokinele au fost propuse drept substanţe somnogene&#xD;
efective. De asemenea, s-a descoperit faptul că reglarea ciclului somn-veghe este realizată prin&#xD;
interacţiunea dintre diverşi neuroni ce controlează starea de veghe şi somnul. În această lucrare,&#xD;
realizăm o scurtă trecere în revistă a neurobiologiei somnului.

    <description>Title: Corelaţii dintre activitatea sistemului citokinic şi proteina C–reactivă pe parcursul şocului hemoragic
Authors: Rotaru, Victoria; Borş, Eleonora; Hangan, Corneliu; Cernit, Veronica
Abstract: Hemorrhagic shock takes place by local and systemic inflammatory processes. A&#xD;
pathogenetic factor of systemic inflammation is acute-phase response. During the acute-phase&#xD;
response, the liver dramatically increases the synthesis of acute-phase proteins, such as&#xD;
fibrinogen and C-reactive protein (CRP). CRP is recognized as a true marker of local and&#xD;
diffuse inflammatory process. Elevated levels of this protein of acute inflammation during&#xD;
hemorrhagic shock are caused by elevated concentrations of cytokines IL-1, IL-6, TNF-α.&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
Şocul hemoragic se desfăşoară prin procese inflamatorii locale şi sistemice. Un factor&#xD;
patogenetic al inflamaţiei sistemice este Răspunsul Fazei Acute (RFA). În timpul RFA în ficat&#xD;
creşte corelativ sinteza proteinei C- reactive (PCR), fibrinogenului, precum şi nivelul citokinelor&#xD;
în sânge. PCR este recunoscută drept un marker fidel al procesului inflamator local şi difuz.&#xD;
Valorile crescute ale acestei proteine a fazei acute a inflamaţiei pe perioada şocului hemoragic&#xD;
sunt determinate de concentraţiile elevate ale citokinelor IL-1-α, IL-6 şi TNF-α.

    <description>Title: Reflections about estimative method of the isolate portal vein contractility
Authors: Saulea, Aurel; Rotaru, Victor; Ojog, Victor
Abstract: The current investigation intended to determine the conditions of portal vein contractions&#xD;
in rats in isometric regime. The proceeding of object preparation as well as experimental phases&#xD;
was described. Main parameters of contractility were highlighted, also the importance of portal&#xD;
vein muscle reactivity at different concentrations of Ca ions. Hypotheses about the origin and&#xD;
mechanism of portal vein muscle contraction were enounced.&#xD;
&#xD;
&#xD;

Prezenta investigaţie determină condiţiile contracţiilor venei porte la şobolan în regim&#xD;
izometric. A fost descrisă desfăşurat manopera de preparare de obiectului de studiu precum şi&#xD;
etapele experimentale. S-au evidenţiat indicii principali ai contractilităţii, cît şi importanţa&#xD;
reactivitaţii muşchiului venos portal la diferite concentraţii a ionilor de Ca2+. Au fost expuse&#xD;
ipoteze privind originea şi mecanismul contracţiei venei porte izolate

    <description>Title: Efectele nespecifice ale estrogenilor
Authors: Cucu, Tatiana; Cucu, Cristina
Abstract: The effects of estrogens upon the cardiovascular system are: prevention of&#xD;
atherosclerosis, improvement of the lipid profile and vasodilation. The effects of estrogens upon&#xD;
the digestive system are: reduction of the intestinal peristalsis and increase of absorption.&#xD;
Estrogens also have neurotrophic and neuroprotective effects, along with the prevention of brain&#xD;
ischemia, they have an antidiabetic action, increase the retention of water and sodium, protect the&#xD;
skeletal system and increase blood coagulation. Estrogens also maintain the normal structure of&#xD;
skin in women by promoting keratinocytes and fibroblasts proliferation, and by stimulating its&#xD;
vascularization.&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
&#xD;
La nivelul sistemului cardiovascular, estrogenii au efect antiaterosclerotic, de ameliorare&#xD;
a profilului lipidic şi de vasodilatare. La nivel digestiv, estrogenii micşorează peristaltismul&#xD;
intestinal, favorizînd absorbţia. Estrogenii mai posedă efect neurotrofic, neuroprotector şi&#xD;
antiischemic cerebral, au acţiune antidiabetică, favorizează retenţia de apă şi sodiu, au efect&#xD;
protector asupra ţesutului osos, majorează coagulabilitatea sîngelui. La nivelul pielii, estrogenii&#xD;
menţin structura ei normală la femei prin promovarea proliferării keratinocitelor, fibroblastelor,&#xD;
prin stimularea vascularizării pielii.
