چکیده انگلیسی


- We used the LPS rat model for induction of mild sepsis.
- We examined behavioural changes, stress parameter, inflammation, and apoptosis.
- The potential role of levosimendan was investigated.
- Levosimendan showed anti-inflammatory and anti-apoptotic properties in spleen.
- Levosimendan failed to show a neuroprotective effect.

Levosimendan shows protective myocardial characteristics and is administered to enhance cardiac contractility in patients. However, currently little is known about levosimendan's effect on brain. The aim of this pilot study was to investigate the long-term effect of levosimendan on brain and during mild rat sepsis in comparison to its peripheral mode of action. Adult rats (n = 40) were divided into four groups with n = 10 per group: (I) sham, (II) levosimendan (283 μg/kg body weight i.v.), (III) lipopolysaccharide (LPS, 8 mg/kg body weight i.p.), and (IV) LPS+levosimendan. Levosimendan was given 24 h after injecting LPS. Psychometric investigations were conducted using a Morris water maze (MWM) and a holeboard test. In cerebral and splenic tissue, IL-1β, Il-6, TNFalpha levels, and apoptosis were determined; cerebral tissue corticosterone concentration was measured 6 days after injecting LPS. Blood cytokine concentrations were determined 1 day and 6 days after injecting LPS. Rats that received an LPS injection spent more time in the outer zone of the MWM according to increased cerebral corticosterone levels, and showed decreased cognitive abilities. LPS induced a reduction in body weight, increased splenic apoptosis and blood cytokine level. Levosimendan showed anti-inflammatory and anti-apoptotic properties in spleen but failed to show a long-term neuroprotective effect.
