The present study examined the effects of Tremella fuciformis(TF) on the learning and memory function and the neural activity in rats with TMT-induced memory *** rats were administered saline or TF(TF 25,50,100mg/kg,p.o.) daily for 21 *** cognitive improving efficacy of TF on the amnesic rats, which was induced by TMT,was investigated by assessing the Morris water maze test and by performing acetylchoine transferase(ChAT) and cAMP responsive element binding protein(CREB) immunohistochemistry. In order to confirm the underlying mechanisms of the memory enhancing effects of TF,we assessed the neurite outgrowth of PC12 *** also administered 18F-Fluorodeoxyglucose and performed a PET/CT scan of the frontal lobe. The rats with TMT injection showed impaired learning and memory of the tasks and treatment with TF produced a significant improvement of the escape latency to find the platform in the Morris water maze at the 2 day compared to that of the control group(after the 2 day,p<0.05).In the retention test,the TF50 group showed increased time spent around the platform compared to that of the control group(p<0.05).Consistent with the behavioral data,TF50 mg/kg significantly alleviated the loss of ChAT-ir neurons in the hippocampus compared to that of the control group(p<0.001).Treatment with TF significantly increased the CREB positive neurons in the hippocampal CA1 area as compared to that of the control *** addition,TF treatment(50mg/kg) increased the glucose uptake approximately sevenfold in the frontal lobe(p<0.001) and it significantly promoted neurite outgrowth of the PC 12 cells(p<0.01),as compared to that of the controls. These results suggest that TF may be useful for improving the cognitive function via regulation of cholinergic marker enzyme activity and neural activity.

Background: Because the cause and etiology of chronic headache is not yet fully explained, the treatment of this symptom is not simple. This study compares the effects of aroma acupuncture and normal acupuncture applied on chronic headache patients, in order to establish a primary data for further studies of new treatments and developments of new practical acupuncture. Methods: 38 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, aroma acupuncture group (Aroma AT group, n=23) and normal acupuncture group (AT group, n=15).
