Cerium conversion treatment was applied on magnesium coatings in a solution containing CeC13. The composition ot the cenum conversion layer on magnesium was investigated using X-ray photoelectron spectroscopy （XPS）, It was revealed that the composition predominately consisted of a three-valent state cerium compound with a relative abundance around 90%. Some of Ce^3＋ was oxidized to Ce^4＋. electrochemical impedance spectroscopy results revealed that the total impedance of cerium-treated samples increased for a short immersion time in NaC1 solution before coating deteriorating. This deterioration was due to the coating porosity increasing and the breakdown of the conversion layer

Corrosion protection afforded by a magnesium coating treated in cerium salt solution on steel substrate was investigated using open circuit potential, polarization curves, and electrochemical impedance spectroscopy （EIS） in 0.005 M sodium chloride solution （NaCl）. The morphology of the surface was characterized by scanning electron microscopy （SEM）, energy dispersive spectroscopy （EDS）, and X-ray diffraction （XRD）. The cerium treated coating was obtained by immersion in CeCl3 solution. The results showed that the corrosion resistance of the treated magnesium coating was improved. The corrosion potential of the treated coating was found to be nobler than that of the untreated magnesium coating and the corrosion current decreased significantly. Impedance results showed that the cerium treatment increased corrosion protection. The improvement of anti-corrosion properties was attributed to the formation of cerium oxides and hydroxides that gave rise to a physical barrier effect.

Sepsis and septic shock are life threatening condition associated with high mortality rate in critically-ill patients. This high mortality is mainly related to the inadequacy between oxygen delivery and cellular demand leading to the onset of multiorgan dysfunction. Whether this multiorgan failure affect the pancreas is not fully investigated. In fact, pancreatic injury may occur because of ischemia, overwhelming inflammatory response, oxidative stress, cellular apoptosis and/or metabolic derangement. Increased serum amylase and/or lipase levels are common in patients with septic shock. However, imaging test rarely reveal significant pancreatic damage. Whether pancreatic dysfunction does affect the prognosis of patients with septic shock or not is still a matter of debate. In fact, only few studies with limited sample size assessed the clinical relevance of the pancreatic injury in this group of patients. In this review, we aimed to describe the epidemiology and the physiopathology of pancreatic injury in septic shock patients, to clarify whether it requires specific management and to assess its prognostic value. Our main finding is that pancreatic injury does not significantly affect the outcome in septic shock patients. Hence, increased serum pancreatic enzymes without clinical features of acute pancreatitis do not require further imaging investigations and specific therapeutic intervention.

Objective: To investigate the effects of perorally administered juice on tetrachloromethane(CCl4)-induced hepatotoxicity model in rats. Methods: Male Wistar rats were tubeadministrated silymarin, Ecballium juice at 0.2 mL/kg and 0.7 mL/kg daily for 3 consequent days, ie. 3.28 μg and 11.48 μg of cucurbitacin B per kg of body weight respectively. On the third day, liver damage was induced by intraperitoneal application of CCl4. On the fourth day, abdominal cavity was macroscopically examined and liver samples were taken for histopathological and immunochemical evaluation. HPLC was used to determine the content of the active substance cucurbitacin B. Results: The experiment revealed that 0.7 ml/kg juice concentration expressed the highest pro-apoptotic activity, but with prevailing negative effects. Compared with the lower concentration, there was an observable vasodilatation with consequent interstitial hemorrhages and a larger scope of inflammatory damage, which suppressed the hepatoprotective effect. In the 0.2 mL/kg concentration, there was a smaller pro-apoptotic activity but other parameters had better results, and the liver parenchyma damage was reversible. Conclusions: No reactions confirming the potentially allergic effect on laboratory rats were observed; its hepatoprotective and anti-inflammatory effect was confirmed on a model of acute liver damage.
