Panax ginseng Meyer (P. ginseng; Korean ginseng) is well known for its medicinal properties. It can alleviate pathological symptoms, promote health, and prevent potential diseases via its anti-inflammatory, antioxidant, homeostatic, and other positive effects on biological metabolism. Although many studies have determined effects of P. ginseng on various diseases, such as cardiovascular, neurological, and immunological diseases, little is known about the effect of P. ginseng on autoimmune diseases. Here, we review a few reports about effects of P. ginseng on autoimmune diseases (e.g., multiple sclerosis, Crohn's disease, ulcerative colitis, atopic dermatitis, and rheumatoid arthritis) and suggest the possibility of P. ginseng as a candidate herbal medicine to prevent and treat autoimmune diseases as well as the need to study it.

The causal organism of Phytophthora disease on Panax ginseng Meyer in Korea was isolated and identified as Phytophthora cactorum. It's pathogenicity, etiology, and possible control measures were investigated. Disease symptoms on various parts of ginseng plants were also described The fungus caused seedling and mature plant blight and root rot. Oospores were easily formed on potato dextrose agar and corn meal agar. Oospores, however, were not formed in the diseased root tissues but did in the in footed shoots such as leaves, petioles, and stems and in the inoculated berries.

Incidence of damping-off callsed by Rhizoctonia solani was 0.6-10.9% at "Yangjik" seedbed in Pocheon, Korea. The seedbeds where the lengths of etiolated stems (underground portion) of ginseng seedlings were 0.78-1.25 cm showed 0.8-3.2% of the disease, while 6.9-10.9% disease incidence was observed at the seedbeds with the longer etiolated stem (1.89-2.26 cm). The pathogen produced a typical girdle symptom on the etiolated portion of ginseng stems close to the soil surface. The deeper the seeds were sown, the more the disease occurred in pot soil inoculated with the pathogen, AG 2-1, showing 18.4, 27.4 and 32.9% of damping-off at the seeding depth of 1, 2 and 4 cm, respectively. Cuticle layers of colored stems (over ground portion) were well - developed to be 42.8, 58.0, and 55.0 um in thickness compared to the etiolated stems with 8.5, 15.0 and 8.0um for seedling, 2 year-old, and 3 year-old ginsengs, respectively, when the disease occurred. In the seedling and 2 year-old ginseng, the colored stems were more rigid than the etiolated. There was however, no difference in rigidness of the stem of the 3 year-old ginseng where the disease is not severe as in seedlings and 2 year-old ginseng plants.ng plants.

고려 인삼중 폐포와 4등급 이하를 유발시키는 90％이상이 적변삼이라고 불리는 인삼의 표피 색택이 붉은 삼이 그 원인이다. 이러한 적변삼은 미국삼보다는 고려 인삼에 서 다량 발견되는 바, 적변은 유전적 요인이 있다고 사료된다. 그러므로 이 연구의 목적은 RT-PCR을 이용하여 인삼적병에 내성을 가지는 유전자를 탐색하기 위하여 실시되었다. 고려인삼 3년근 1개체 중에서 적변이 발생된 부위와 건전 부위의 RNA를 추출하여 형성된 cDNA를 여러개의 random primer를 사용하여 PCR 증폭을 한 결과 정상 부위의 cDNA에서 발견되지 않는 band가 적변삼의 부위에서 발견되었다. 따라서 band가 형성된 부위의 유전자가 적변과 관련될 가능성이 있는 것으로 사료되고 이러한 유전자는 향후 염기서열을 분석하여 어떠한 유전자인지 판명을 하여야 하며 적변관련 유전자이면 선발마커로서 사용되고 또한 형질전환을 통한 적변내성 인삼계통을 육성할 수 있으며, 만약 적변과 관련이 없는 유전자로 판명된다면 더 많은 primer를 사용하여 적변관련 유전자를 탐색해야 할 것이다.

Ginseng is one of the most popular herbs throughout the world. Ginsenosides, the active constituent of ginseng, have been suggested to have diverse effects on cardiovascular, immune, mood and endocrine systems as well as cognitive performance. Many studies have revealed the beneficial effect of ginseng on cognition in normal human subjects and in animals. Recently, a few studies showing effects of ginseng on the patients with Alzheimer's disease have been reported. However, the underlying mechanism is not clear at this stage and it is still obscure whether ginseng is cognitive stimulant or disease modifying agent. More detailed studies exploring the relationship between clinical efficacy and pathophysiology are required.

Ginseng, the root of the Panax ginseng, has been a popular and widely-used traditional herbal medicine in Korea, China, and Japan for thousands of years. Now it has become popular as a functional health food and is used globally as a natural medicine. Evidence is accumulating in the literature on the physiological and pharmacological effects of P. ginseng on neurodegenerative diseases. Possible ginseng- or ginsenosides-mediated neuroprotective mechanisms mainly involve maintaining homeostasis, and anti-inflammatory, anti-oxidant, anti-apoptotic, and immune-stimulatory activities. This review considers publications dealing with the various actions of P. ginseng that are indicative of possible neurotherapeutic efficacies in neurodegenerative diseases and neurological disorders such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis and multiple sclerosis.

Red ginseng (RG) is widely used as a herbal medicine. As the human lifespan has increased, numerous diseases have developed, and RG has also been used to treat various diseases. Neurodegenerative diseases are major problems that modern people face through their lives. Neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis are featured by progressive nerve system damage. Recently, neuroinflammation has emerged as a degenerative factor and is an immune response in which cytokines with nerve cells that constitute the nervous system. RG, a natural herbal medicine with fewer side effects than chemically synthesized drugs, is currently in the spotlight. Therefore, we reviewed studies reporting the roles of RG in treating neuroinflammation and neurodegenerative diseases and found that RG might help alleviate neurodegenerative diseases by regulating neuroinflammation.

In this study it was found that the enzyme activities of diseased ginseng contributed greatly on the development of its root-rot disease. The 4i sensed ginseng showed higher activities of $\alpha$-amylase, p amylase, invertase, catalase, and cellulase than those of fresh one. The increased enzyme activities of diseased ginseng were originated in those from infected pathogens, which showed a proportional relationship between enzyme activities and root-rot power of them. The increases of enzyme activities during incubation of inoculated ginseng could be considerably depressed by controlling culture environments as to temperature below 4$^{\circ}C$, pH 8-9, and relative humidity about 60%, Some metal ions and organic reagents also inhibited the enzyme activities of diseased ginseng. But their inhibitory effects were not so great that they might be used to protect the disease.

Traditionally, Asian ginseng or Korean ginseng, Panax ginseng has long been used in Korea and China to treat various diseases. The main active components of Panax ginseng is ginsenoside, which is known to have various pharmacological treatment effects such as antioxidant, vascular easing, anti-allergic, anti-inflammatory, anti-diabetes, and anticancer. Most reactive oxygen species (ROS) cause chronic diseases such as myocardial symptoms and cause fatal oxidative damage to cell membrane lipids and proteins. Therefore, many studies that inhibit the production of oxidative stress have been conducted in various fields of physiology, pathophysiology, medicine and health, and disease. Recently, ginseng or ginsenosides have been known to act as antioxidants in vitro and in vivo results, which have a beneficial effect on preventing cardiovascular disease. The current review aims to provide mechanisms and inform precious information on the effects of ginseng and ginsenosides on the prevention of oxidative stress and cardiovascular disease in animals and clinical trials.
