Objective To investigate the effect of ethanol on level of the main hippocampal subtype of muscarinic receptor(M1)in mice,and evalu?ate whether the content change on this receptor could be linked with alterations in cognition,so as to further reveal the mechanism of brain damage in?duced by ethanol. Methods Sixty female mice were randomly divided into four groups. The model mice were induced by intragastric administration of ethanol at dose of 8%,16%,and 32%respectively of 0.2 mL/10 g for 8 weeks according to the protocol,and control group were treated with intra?gastric administration of distilled water. The capability of learning and memory were examined by Morris water maze,and ELISA method was used to measure the M1 receptor content in hippocampus in each group of mice. Results Compared with first day,the mean escape latency period on the fifth day was significantly shortened in each group. There was no significant difference between ethanol and control group for the mean escape latency period on the fifth day. Compared with the control group,the active time in the target quadrant was significantly shortened in 16%and 32%ethanol group. M1 receptor content in hippocampus formation was significantly decreased in all the ethanol group mice. The ethanol concentration was nega?tive correlated with the M1 receptor content. Conclusion Chronic alcoholism can induce the memory impairment in mice,which might be associat?ed with the low level of M1 receptor subtype in hippocampus of mice.

Objective Adenosine receptor agonist NECA has a certain myocardial protection, but the specific mechanism is not clear.This paper aimed to study the effect and mechanism of NECA inhibiting endoplasmic reticulum stress to against myocardial ischemia reperfusion injury in rats.Methods 56 Wistar rats of SPF grade were selected and divided into Sham group, I/R group, NECA group and TUDCA group through random number table method.We established the isolated rat heart ischemia reperfusion model by using the Langendorff device.Sham group: heart threaded but not ligated, Kerb-Henseleit buffer continuous infusion 170min;I/R group: heart stability 20min, ischemia 30min, reperfusion 2h;NECA group and TUDCA group: heart stability 20min, ischemia 30min, reperfusion 2h, perfusion solutions containing 0.1μmol/L NECA and 30μmol/L TUDCA were respectively given at 5min before reperfusion, and ended at 30min after reperfusion.Transmission electron microscope was used to evaluate alterations of the myocardial ultrastructures.Western blot analysis was used to detected the expression levels of endoplasmic reticulum stress IREl-XBPl signaling pathway marker protein IRE1α, XBP1s.Immunohistochemical staining was used to detect the expression of IRE1α.Results The results of transmission electron microscopy showed that most of the myofilament ruptured, sarcomere contracture deformation, visible mitochondrial vacuoles degeneration in I/R group, and injury in NECA group and TUDCA group were less than the I/R group, appeared as the filaments arranged more neat, sarcoma only had mild contracture.Immunohistochemical results showed that IRE1αpositive staining was not found in the sham group, and the area of positive staining of IRE1α in I/R group was significantly increased, while the NECA group and TUDCA group were significantly decreased.Compared to the Sham group, the expression level of IRE1α and XBP1s was significantly increased in I/R group(P<0.05);but compared with the expression level of IREα and XBP1s in I/R group(1.72±0.27, 0.97±0.19), the NECA group(1.14±0.16, 0.6±0.13) and the TUDCA(1.07±0.27, 0.58±0.15) group were significantly decreased(P<0.05).Conclusion NECA can reduce endoplasmic reticulum stress through inhibiting IREl-XBPl pathway to protect the myocardium.
