In Korean ginseng, Panax ginseng C.A Meyer, it was difficult to isolate chloroplast DNA with classical methods, because of the high polysaccharide content of ginseng chloroplast The simple and efficient method of chloroplast DNA isolation from ginseng leaves has been developed by motificalion of recently advanced methods. Also, it can be successfully applied to ctDNA isolation of Chinese cabbage, radish, petunia tobacco as well as ginseng. Isolated chloroplast DNA from ginseng was digested with various restriction endonucleases. It was estimated that the molecular weight of Korean ginseng chloroplast DNA was about 142 kb. There was no difference in restriction endonuclease digestion patterns between two variants of Korean ginseng, which are Jakyung-Jong (violet-stem variant) and Hwang- sook-Jong (yellow-berry variant).

Attempts have been made upon the temperature response of the rat induced by some central nervous system depressants as well as stimulants, so as to secure some hidden facets of Panax Ginseng acting upon central nervous system. Although considerable works have been done with regard to Panax Ginseng, it is quite apparent that neither definite implication in terms of its effective chemical constituents is with us nor its pharmacological activity thus far. The author could, however, arrive at some results through procedures preceded by intraperitoneal administration of various drugs in combination with Panax Ginseng in albino rats, that is: (1) Nembutal and chlorpromazine displayed a highly inhibitory effect upon temperature response in the presence of Panax Ginseng, while meprobamate, reserpine, phenacetin and aspirin exerted potentiation actions upon hypothermia. Phenobarbital, serotonin and histamine, on the contrary, did not appear to produce any effect of significance. (2) Nembutal with Panax Ginseng caused prolongation of hypnosis in rat, whereas sodium phenobarbital did not have any effect on it. (3) $LD_{-50}$ in each experimental group of administration of central nervous system stimulants such as strychnine, picrotoxin with Panax Ginseng, necessitated marked increase in the lethal doses. The observations from this study seemed to imply that the complicated mechanism of action of Panax Ginseng might be referred to both central nervous depressive action and influence to basal metabolic rate of mammalian.

Liver and kidney are specific organs which play an active role in biotransformation and detoxification mechanisms. Ant adverse effect of chemicals or heavy metal can cause the delay or fade in these mechanisms. Present study was designed to find out the protective effect of Panax ginseng extract on renal functions altered by mercuric chloride (heavy metal) in albino rat. Fifty albino rats were divided into 10 groups. Five groups for acute study and five groups for sud-acute study viz. control group (Tween 20 and distilled water), mercuric chloride treated group (0.926 mg/kg body wt. for acute and 0.044 mg/kg body wt. for sub-acute group after calculated $LD_{50}$ (9.26 mg/kg body wt.) by probit analysis (Finney, 1971), Panax ginseng extract treated group (10 mg/kg body wt. for acute and sub-acute sets), mercuric chloride treated followed by Panax ginseng extract and Panax ginseng extract followed by mercuric chloride group. All doses were given orally by gavage tube. The result revealed that the serum urea and creatinine significantly increased in mercuric chloride treated group, while significantly decreased (p<0.01) in Panax ginseng extract group after acute and sub-acute treatment. The biochemical estimation is also confirmed by nephropathological aspect. However, the Panax ginseng extract treated followed by mercuric chloride group is more prominent than the mercuric chloride treated followed by Panax ginseng extract group. It can be concluded that Panax ginseng extract had a protective nature on renal functions against mercuric chloride toxicity in albino rats.

There have been several reports regarding the effects of Panax ginseng on allergy reactions. However, they are very sporadic and no systemic yet. To study the effects of Panax ginseng on hypersensitivity, either ginseng total saponin (GTS, 200mg/kg, oral, two hours prior to experiments) or ethanol extract (50 and 200 mg/kg, oral, one week) was administered. Various parameters were employed to assess the anti-allergic actions of Panax ginseng 48hr passive cutaneous anaphylaxis (PCA), skin reactions, histamine release from rat peritoneal mast eel Is, and lipoxygenase activity. In 48hr PCA, and in skin reactions induced by chemical mediators (histamine, serotonin) and mediator releaser (compound 48/80), Panax ginseng did not suppress sensitized immune functions, rather showed tendency to increase the histamine-induced vascular permeabi1ity. Panax ginseng did not inhibit lipoxygenase activity either.

From the underground part of Panax vietnamensis Ha et Grushv., commonly known as Vietnamese ginseng, 50 triterpene glycosides including 24 new dammarane saponins named visa-ginsenosides-Rl-24 were isolated and identified. The structure of the new saponins was elucidated based on chemical and spectroscopic evidence. The saponin composition of Vietnamese ginseng is almost similar to that of ginseng (Panax ginseng C.A. Meyer) and other cultivated Panax spp. However, the content of ocotillos-type saponins, especially that of the major saponin, majonoside-R2 (5.29% yield), was surprisingly very high. The pharmacological activities of Vietnamese ginseng are essentially similar to those of ginseng. In addition, it has marked antibacterial activity against pathogenic Streptococcus app. and is effective in treatment of granular angina. The chemical composition and pharmacological activities have made Vietnamese ginseng an interesting member of Panax spp. from chemotaxonomical and pharmacological points of view,

This overview is focused on Panax ginseng, one of the most commonly used herbal remedies. The currently available data regarding its clinical efficacy is somewhat confusing, despite the fact that many clinical trials and systematic reviews have been published. The risks of Panax ginseng seem to be only minor. Numerous mechanisms of action have been described. Future studies of this fascinating herbal remedy seem warranted but they should overcome the methodological limitations of the previous research.

The influence of Panax ginseng and Acanthopanax on the metabolism of hens are studied experimentally. The hens are fed with three dose levels of ethanol extract of Panax ginseng and Acanthopanax for 24 months and for comparing, there are control hens and young control hens. The results are as follows. 1. Hemoglobin, hematocrit and erythrocyte sedimentation rate values of hens fed with Panax ginseng and Acanthopanax are not significantly. different from control group. There is tendency of decreasing of erythrocyte sedimentation rate with aging. 2. The serum total lipid values of hens fed with Panax ginseng and Acanthopanax have tendency of increment compared with control group, especially in large dose treated hens of Panax ginseng and it is statistically significant. The serum cholesterol levels of all treated hens seem to be increased without significance statistically. Serum triglyceride level is higher in young hens compared with aged, and Panax ginseng and Acanthopanax treated hens reveal much higher values than control hens. So the increment of triglyceride levels in the Panax ginseng and Acanthopanax treated hens may be mainly contribute to increment of total lipid content. 3. Long-term administration of Panax ginseng and Acanthopanax seem to increase total serum protein content. Such increment seem to be due to the increment of globulin, especially gamma globulin, which is statistically significant in the large dose group of Acanthopanax. There are no differences of serum albumin levels of all the groups. 4. The blood glucose level and the glycogen content of liver and muscle have no difference among all the experimental groups. To summarize the results, the effects of Panax ginseng and Acanthopanax on the metabolism of hens have similarity in the majority of data of this experiment, and seem to be mainly influence to lipid and protein metabolisms by increasing serum triglyceride and globulin, especially gamma globulin.
