Adjuvant effects of fermented red ginseng extract on advanced non-small cell lung cancer patients treated with chemotherapy / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the adjuvant therapeutic effects of fermented red ginseng (FRG) extract on non-small cell lung cancer (NSCLC) patients treated with chemotherapy.</p><p><b>METHODS</b>A total of 60 patients with advanced NSCLC were divided into two groups using a random number table, i.e., the gemcitabine plus cisplatin (GP) chemotherapy alone group (26 patients) and the FRG + GP chemotherapy group (34 patients), for 60-day treatment. Patients were then assessed according to the Fatigue Symptom Inventory, Chinese medicine symptoms score, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Karnofsky Performance Status Scale, and Functional Assessment of Cancer Therapy-Lung. In addition, chemotherapy toxicity and tumor biomarkers were measured.</p><p><b>RESULTS</b>For NSCLC patients after chemotherapy, FRG extract significantly improved the FSI score, CM symptoms score, psychological status, physical conditions, and quality of life and reduced chemotherapy toxicity, but the expression levels of carcinoembryonic antigen, cytokeratin-19 fragments, and neuron-specific enolase were not significantly different between the chemotherapy alone and the FRG + chemotherapy groups or between pre- and post-treatments.</p><p><b>CONCLUSIONS</b>This study demonstrated that FRG extract had an adjuvant effect on advanced NSCLC patients treated with chemotherapy. Further studies with a larger sample size will verify the current findings.</p>

Enhancement of Exercise Capacity by Black Ginseng Extract in Rats / 한국실험동물학회지

This study was carried out to investigate an enhancing effect of black ginseng extract (BGE) on exercise capacity in an endurance exercising animal model. Fifty Sprague-Dawley rats were assigned to 5 experimental groups including non-training control, training control, and 3 treated groups (BGE at doses of 75, 150 and 300 mg/kg). The animals were treated with BGE for 6 weeks and their exercise ability in the maximal running distance test was determined using a treadmill every week. The blood lactic acid (LA) level and the activity of citrate synthase (CS) in the muscle were also measured after the exercise. The levels of glucose and glucose-6-phosphate (G-6-P) in the liver and muscle were determined using commercial assay kits. BGE treatments at the doses of 150 and 300 mg/kg significantly increased the exercise capacity compared with the non-training control or training control groups (P<0.05). The level of blood LA was decreased but the activity of CS was increased by the treatment of BGE at the dose of 300 mg/kg compared with the training control group. The level of G-6-P in the liver was elevated by the treatment of BGE at the dose of 300 mg/kg, compared to the training group. As compared with non-training control group, the treatments of BGE increased the levels of glucose and G-6-P in the liver and soleus muscle of rats. These results indicate that BGE have a potential for promoting exercise capacity by increasing CS activity in the muscle and decreasing LA in the serum of rats. These results also suggested that BGE can be used as a candidate supplement of health food products for promoting endurance exercise capacity in human athletes.
