In order to elucidate the effects of Panax Ginseng on the pharmacokinetics of sulfobromophthalein (BSP) in a pathological condition, patho-physiological changes, the kinetics of the disappearance of BSP from the blood and appearance in the bile were studied in rats. Group I , the control group, was produced by repeated injection of olive oil 0.1ml/100g under the skin of the back twice a week for 9 weeks. Group II , the Ginseng pretreated group, was produced by administration of Ginseng total saponin 200mg/kg/day P.O. for 10 days and subsequent injection of $CCl_4$ 0.1ml/100g under the skin of the back twice a week for 9 weeks. Group III , the chronically intoxicated group, was produced by repeated injection of $CCl_4$ 0.1ml/100g under the skin of the back twice a week for 9 weeks. The results obtained were summarized as follows; 1. The activities of GOT GPT of rat blood serum, body weight, and liver weight were affected by the pretreatment with Ginseng saponin. 2. The kinetics of the disappearance of BSP from the blood were affected by the pretreatment with Ginseng saponin. 3. The appearance of BSP in the bile was significantly affected by the pretreatment with Ginseng saponin.

This study deals with internal state and tissue density analysis methods for red ginseng grade determination. For internal measurement of red ginseng, there have been various studies on nondestructive testing methods since the 1990s, It was difficult to grasp the most important inner hole and inside whites in the grading. So in this study, we developed a closed capturing device for infra-red illumination environment, and developed an internal measurement system that can detect the presence and diameter of inner hole and inside whites. Made devices consisted of infrared lights with a high transmission rate of red ginseng in 920 nanometer wave band, a infra-red camera and a Y axis actuator with a red ginseng automatically controlled focus on the camera. The proposed algorithm performs an auto-focus system on the Y-axis actuator to automatically adjust the sharp focus of the object according to the size and thickness. Then red ginseng is rotated $360^{\circ}$ at $1^{\circ}$ intervals and 360 total images are acquired, and reconstructed as a sinogram through Radon transform and Back-projection algorithm was performed to acquire internal images of red ginseng. As a result of the algorithm, it was possible to acquire internal cross-sectional image regardless of the thickness and shape of red ginseng. In the future, if more than 10,000 different shapes and sizes of red ginseng internal cross-sectional image are acquired and the classification criterion is applied, it can be used as a reliable automated ginseng grade automatic measurement method.

This study was conducted to define the seasonal differences in the morphological characteristics, the photosynthetic abilities and the dark respirations of the 4-year old ginseng leaves. Chlorophyll-a content in the ginseng leaf was significantly decreased at September than at June but content of chlorophyll-b was not showed seasonal difference. At June, the amounts of chlorophyll a and b in the ginseng leaves grown in the back row were rather abundant than those grown in the front row, but no significant differencies were detected between rows at September. The estimated optimum light intensity for the photosynthesis of ginseng leaves was higher at June than at September and higher in the front row than the back row but was significantly decreased by air temperature above 25$^{\circ}C$. The light compensation point was elevated in higher temperature and at September than June. The amount of photosynthesis was significantly increased in the ginseng plant grown in the front row than the back row at June but the reverse was significant at September. The highest photosynthesis was observed in temperature range of 20 - 25$^{\circ}C$ at June and range of 15 -20$^{\circ}C$ at September. The optimum temperature range of photosynthesis was 21$^{\circ}C$ to 25$^{\circ}C$ at June and 14$^{\circ}C$ to 21$^{\circ}C$ at September, and that was higher in the back row than the front row. High temperature significantly stimulated the dark respiration of ginseng leaves and the respiratory quotients(Q$\_$10/) of the ginseng leaves showed a significant seasonal variation.

To evaluate the anticarcinogenic effect and its mechanism of red ginseng, the mice were treated with red ginseng and received subcutaneous Bl6 melanoma cell line injection on the back. Tumor incidence was same (100%) both in water and red ginseng-treated groups, but tumor production was delayed in red ginseng-treated group. Survival time was somewhat longer in red ginseng-treated group. The histopathological findings were similar in both groups, but lymphocytic infiltration around the tumor and melanin production in the tumor cells were prominent in the red ginseng-treated group. Flow cytometric analysis on T lymphocytes and natural killer cells revealed increased $T_H$/$T_S$ ratio and increased NK cells in red ginseng-treated group. These results suggest that the anticarcinogenic effect of red ginseng may be exerted by the increased cell-mediated immunity and natural killer cell activity.

This study was carried out to investigate the effect of seasonal changes on some of the morphological and physiological characteristics, including the photosynthetic abilities and dark respiration, of young ginseng plants due to planting location under shading. The results obtained are as follows: 1. Seedlings and 2-year old plants planted in the back rows appeared to have broader leaf area, and their leaf weight greatly increased in September. Chlorophyll content was significantly reduced in September rather than in June and the plants in the back rows had more chlorophyll content than those in the front rows. 2. There was no difference in the light compensation point between the front and back rows in June, while in September the light compensation point of 2-year old ginseng leaves was much lower for plants in the back rows compared with those in the front rows. A difference in the light saturation point was not noticeable between plants in the front and back rows in June and September. But the light saturation point of 2-year old ginseng leaves at $15^{\circ}C$ was high in June, while it was high at $20^{\circ}C$ high in September. 3. Maximum photosynthetic ability was attained at $15^{\circ}C$ in June and at $20^{\circ}C$ in September. During June no significant difference in photosynthetic ability was found between plants in the front and back rows, but in September the amount of photosynthesis was significantly increased at the leaves of seedlings as well as 2-year old plants planted in the back rows. 4. The optimum temperature for maximum photosynthesis in 2-year old plants ranged from $14.0^{\circ}C$ to $14.5^{\circ}C$ in June and from $19.5^{\circ}C$ to $20.5^{\circ}C$ in September. However, the optimum temperature for maximum photosynthesis in the seedlings was from $21.2^{\circ}C$ to $21.6^{\circ}C$ in September, but a significant difference in the optimum temperature for the maximum photosynthesis in seedlings and 2-year old plants was not noticeable between the front and back rows. 5. The respiration rate was rather high in seedlings compared with 2-year old plants. During September the respiration rate in seedlings was much lower in the back rows than in the front rows. The rate of increase in the respiration of 2-year old plants was higher at September than June. The increase in respiration rate due to temperature was more significant in seedlings than 2-year old plants. 6. In September, the level of $Q_{10}$ in 2-year old plants was much lower than that found in seedlings. During June, 2-year old plants showed lower $Q_{10}$ levels at a temperature difference between $15^{\circ}C$ and $25^{\circ}C$; but in September this occurred at a temperature difference between $20^{\circ}C$ and $30^{\circ}C$.

New shoot growth of Panax ginseng root was investigated comparing with burley and soybean from l0$^{\circ}C$ to 30$^{\circ}C$ under dark. Shoot growth ceased by 12days at 30$^{\circ}C$ and optimum temperature appeared to be 15$^{\circ}C$/20$^{\circ}C$ (15hrs/9 hrs) , and 15$^{\circ}C$/15$^{\circ}C$ for ginseng. Shoot growth seems to be Poor below l0$^{\circ}C$. Temperature for maximum growth 20$^{\circ}C$/20$^{\circ}C$ for barley and 20$^{\circ}C$ /25$^{\circ}C$ for soybean. Barley did not germinate above 25$^{\circ}C$/25$^{\circ}C$, but grow better than soybean below 15$^{\circ}C$/25$^{\circ}C$. Fresh weight of 2 weeks suggesting cessation of water uptake at higher temporal use. Ginseng showed greater root ply s shoot of ginseng was linearly increased at 15$^{\circ}C$ but did not increased at 25$^{\circ}C$ after occurence of die-back of new shoot or root rot above 25$^{\circ}C$.

Ginseng was the most revered of the herbs in ancient times in China, Korea, Japan, America. Ginseng was discovered over 5000 years ago in the mountains of Manchuria, China. References to ginseng are found in books dating back more than two millennia. It is revered by the Chinese people as it is considered a herb for everything use and therefore for a wide range of diseases (currently its Latin name derived from the Greek panacea, meanings, that is, for everything). So, it was used exclusively by the Chinese Emperor's, and they were willing to pay the price without problems. Increasing its fame, ginseng brought a flourishing international trade that allowed Korea to supply China with silk and medicines in exchange for wild ginseng and later along with what grows in America.

There has been general tendency to explain the traditional ginseng efficacy through the pharmacological and biochemical activities of ginsenosides. However, when we analyze the pharmacological and biological data on ginseng reported yet, we can easily arrive at the conclsion that most of the data on pharmacological and biological activities must have been obtained using impure ginsenoside samples, which should contain some non-saponin constituents as impurities. Based on the above back-ground, the non-saponin constituents of ginseng were studied in our laboratory. Phenolic substances including Maltol, Vanillic Acid, Salicylic Acid, Ferrulic Acid and Caffeic acid and impure ginsenoside samples were found to show strong antioxidant and anti-fatigue activities, while pure ginsenosides were devoid of the activities. Maltol, one of antioxidant components In Korean red ginseng drew a special interest due to its very low pro-oxidant activity. The antioxidant activity of ginseng may be considered as scientific basis for the antiageing activity which was described in traditional medicinal material book as "long-term medication of ginseng will improve bio-efficiency and extend life-span" The lignin components, another non-saponin consitutents, isolated from ginseng extract In our laboratory may eplain the hepato-protective activity of ginseng which has been repeatedly rtaimed as one of the efficacies of ginsenosides. The P-carboline alkaloids isolated in our laboratory as one of the non-saponin constituents of ginseng may play some pharmacological activities which should also be investigated. Present paper will include chemistry and biochemical aspects of the non-saponin constituents of ginseng with special interests for the explanation of traditional ginseng efficacy on modern scientific basis.fic basis.

This study was conducted to define the effects of light transparent rate of the shading on the photosynthesis ability of the ginseng leaves and their seasonal changes. Regardless the effects of light transparent rate of shading and age of ginseng plant, 10,000 lux was the most adequate light intensity for the maximum photosynthesis of ginseng leaves and seasonal difference was not significant. The ginseng plants which were grown under 10 to 15 percent light transparent shading showed the highest photosynthesis ability. The photosynthesis ability of ginseng leaves was significantly decreased in September than June and the decreasing rate was higher at the ginseng plants planted on back rows than front rows. In June, the ginseng plants grown under 10 to 15 percent light transparent shading showed high respiration amount but in September, those grown under 20 to 25% light transparent shading showed the highest respiration. The amount of chlorophyll of ginseng leaf was significantly decreased by increasing light transparent rate of shading.

Background: Previous research has suggested that single doses of a standardised Panax ginseng extract can decrease fasted blood-glucose levels and modulate cognitive performance in healthy young volunteers. The latter has generally been seen in terms of improved secondary memory performance. However, both the cognitive effects of chronic administration of ginseng and the potential modulation of working memory have received comparatively little research attention. Aims: The current double-blind, placebo-controlled, balanced cross-over study investigated the effects of 8-weeks administration of Korean ginseng extract (200 mg) on cognitive performance, gluco-regulatory parameters and ratings of subjective mood and 'quality of life'. Methods: 'Eighteen healthy young participants were assessed pre-dose and 3 hours post-dose on the mornings of Day 1, Day 29 and Day 57 of 8 week treatment regimens of both placebo and ginseng. A four-week placebo wash-out separated the treatment phases. Each assessment included the Cognitive Drug Research battery, computerised working memory tasks, and Bond-Lader mood scales. The WHO Quality of Life scale (WHOQOL-BREF) was completed once per visit. Gluco-regulatory parameters were assessed with assays of blood glucose, insulin and HbA1c. Results: Data from the 16 participants that completed the study showed that there were no significant, acute treatment related differences on Day 1 of treatment, or in gluco-regulatory parameters throughout the study. However, time related performance improvements were evident following chronic administration of ginseng on the '3-Back' and 'Corsi-block' computerised working memory tasks. Ginseng was also associated with an improved score on the 'social relations' subscale of the WHOQOL-100, and a significant shift on the 'calm' factor of the Bond-Lader mood scales (from calm/relaxed towards excited/tense). Conclusion: The results of the current study suggest that Korean ginseng extract can modulate working memory performance and subjective ratings of 'quality of life' and mood. Replication with a larger sample size may further elucidate the actions of this product.
