An open-label trial of Korean red ginseng as an adjuvant treatment for cognitive impairment in patients with Alzheimer's disease

J.-H. Heo
Background and purpose:, Ginseng is one of the most popular herbs worldwide. Ginseng has various medical applications, and it seems to have significant effects as a cognition-enhancing drug. In this study, we examined the efficacy of Korean red ginseng (KRG) as an adjuvant therapy to conventional anti-dementia medications in patients with Alzheimer's disease. Methods:, The trial was designed as a 12-week randomized study. Sixty-one patients (24 males and 37 females) with Alzheimer's disease were randomly assigned to one of the following treatment groups: low-dose KRG (4.5 g/day, n = 15), high-dose KRG (9 g/day, n = 15) or control (n = 31). The Alzheimer's Disease Assessment Scale (ADAS), Korean version of the Mini-Mental Status Examination (K-MMSE) and Clinical Dementia Rating (CDR) scale were used to assess the change in cognitive and functional performance at the end of the 12-week study period. Results:, The patients in the high-dose KRG group showed significant improvement on the ADAS and CDR after 12 weeks of KRG therapy when compared with those in the control group (P = 0.032 and 0.006 respectively). The KRG treatment groups showed improvement from baseline MMSE when compared with the control group (1.42 vs. ,0.48), but this improvement was not statistically significant. Conclusions:, KRG showed good efficacy for the treatment of Alzheimer's disease; however, further studies with larger samples of patients and a longer efficacy trial should be conducted to confirm the efficacy of KRG.

Phytoceuticals: Mighty but ignored weapons against Helicobacter pylori infection

Sun-Young LEE
Helicobacter pylori (H. pylori) infection causes peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphomas and gastric adenocarcinomas, for which the pathogenesis of chronic gastric inflammation prevails and provides the pathogenic basis. Since the role of H. pylori infection is promoting carcinogenesis rather than acting as a direct carcinogen, as several publications show, eradication alone cannot be the right answer for preventing H. pylori -associated gastric cancer. Therefore, a non-antimicrobial approach has been suggested to attain microbe-associated cancer prevention through controlling H. pylori -related chronic inflammatory processes and mediators responsible for carcinogenesis. Phytoceutical is a term for plant products that are active on biological systems. Phytoceuticals such as Korean red ginseng, green tea, red wine, flavonoids, broccoli sprouts, garlic, probiotics and flavonoids are known to inhibit H. pylori colonization, decrease gastric inflammation by inhibiting cytokine and chemokine release, and repress precancerous changes by inhibiting nuclear factor-kappa B DNA binding, inducing profuse levels of apoptosis and inhibiting mutagenesis. Even though further unsolved issues are awaited before phytoceuticals are accepted as a standard treatment for H. pylori infection, phytoceuticals can be a mighty weapon for either suppressing or modulating the disease-associated footprints of H. pylori infection.

The Effect of Korean Red Ginseng Extract on the Relaxation Response in Isolated Rabbit Vaginal Tissue and Its Mechanism

Sun-Ouck Kim MD
ABSTRACT Introduction., Ginseng is an herbal medicine with a variety of biological activities. Aim., The purpose of this study was to investigate the effect of Korean red ginseng (KRG) extract on the relaxation response in isolated rabbit vaginal tissue and its mechanism as a potential therapeutic agent for female sexual dysfunction. Method., Strips of rabbit vagina were mounted in organ chambers to measure isometric tension. After the strips were precontracted with phenylephrine, the contractile responses to KRG extract (1,20 mg/mL), nitric oxide inhibitor (N[omega]-nitro-L-arginine methyl ester [L-NAME]), an inhibitor of soluble guanylate cyclase (methylene blue), an inhibitor of Ca2+ -activated K+ channels (tetraethylammonium [TEA]), and an adenosine triphosphate (ATP)-sensitive K+ channel blocker (glybenclamide) were examined. Main Outcome Measures., The relaxation of the vaginal tissue strip was assessed after treating KRG extract or other chemicals. Results., KRG (1,20 mg/mL) extract relaxed the vaginal tissue strip in a dose-dependent manner up to 85%. The relaxation effect was significantly inhibited by L-NAME (30 ÁM) and methylene blue (30 ÁM) (P < 0.05). In addition, KRG inhibited the contraction induced by depolarization with 10, 20, and 40 mM KCl. The KRG-induced relaxation effect was significantly inhibited by TEA (300 ÁM) (P < 0.05), and not by glybenclamide (30 ÁM). Conclusions., These data show that KRG extract has a relaxing effect on rabbit vaginal smooth muscle tissue. These effects might be mediated partly through the NO pathway and hyperpolarization via Ca2+ -activated K+ channels. Kim S-O, Kim MK, Lee H-S, Park JK, and Park K.
