ABSTRACT
Objective To investigate the effects of cognitive impairment in hippocampus on glucose and lipid metabolism, and its relations with gastrointestinal motility. Methods The Aβ1-42 was injected into the hippocampus of rats. Levels of glucose and lipid were detected. The changes of gastrointestinal motility were detected by the type-B ultrasonic and the ink-pushing experiments. Hippocampal neurons apoptosis was detected by the TUNEL assay. Results In the experimental group, FPG, TG, TC, LDL were (7.92 ± 0.29) mmol/L, (2.24 ± 0.12) mmol/L, (4.67 ± 0.12) mmol/L, (2.41 ± 0.12) mmol/L, respectively, with significant differences among these three groups (P < 0.05). Compared with the sham group and the control group, the number of bowel movements per unit time (2.13 ± 0.83) times, gastric emptying rate (44.35 ± 7.53) % and the small intestinal propulsion rate (57.60 ± 7.82)%in the experimental group were significantly decreased (P<0.05). The experimental hippocampal neuronal apoptosis index was an average of (64.98 ± 3.70)%, which was significantly higher than that in the sham group and the control group (P < 0.05). Conclusion Hippocampal cognitive impairment can elevate the blood lipid level, which may be associated with the hippocampal neuronal apoptosis and the gastrointestinal motility disorders.
