The effect of ginseng on gastric ulcer and gastric acid secretion was investigated in pylorus-ligated rats. Methods: Sprague-Dawley strain rats were used after 24 hours fast. Pylorus-ligation was performed under light ether anaesthesia, then gastric mucosal damage was evoked in conscious pylorus-ligated rats by the administration of subcutaneous (s.c.) indomethancin (20mg/kg), s.c. histamine (150mg/kg) or by pylorus-ligation (Shay ulcer). Ginseng was given by intragastric (i.g.) or intraperitoneal (i.p.) route simultaneously with the ulcerogens. Rats were killed after 3h (indomethacin) and histamine models) or after 18h (Shay ulcer), when the gastric secretory responses, the number and severity of gastric mucosal lesions and mucosal mucus content deetermined. the effect of i.p. ginseng on basal gastric acid secretion and on gastric acide secretion in indomethacin (20mg/kg, s.c.)-treated rats was also investigated in urethane anesthetized rats. Gastric acid secretion was measured by flushing of the gastric lumen with saline every 15min through an oesophageal cannula. Results: In conscious pylorus-ligated rats, i.g. ginseng(12.5-50mg/
; 50-200mg/kg) protected against gastric mucosal lesions evoked by s.c. indomethacin or s.c. histanmine in the d3-h pylorus-lighted rat, withoutmodifying gastric acid secretory responses. Ginseng given i.p. (150 or 200mg/kg) did not reduce the gastric lesions produced by histamine or by ligating the pylorus (Shay ulcer) Ginseng given orally in 50mg/
(200mg/kg) increased gastric mucus secretion in saline- and indomethacin-treated conscious pylorus-ligated rats. In anaesthetized rats ginseng (50 or 200mg/kg) did not modify basal gastric acid secretion or gastric acid secretion in the indomethacin-treated rats. Conclusions: ginseng given orally exerts gastroprotective effects in the rat stomach. Such anti-ulcer effect does not involve changes in gastric acid secretory responses. In addition, ginseng possesses stimulatory effect on gastric mucus secretion, which could be one mechanism by which the compound exerts its antiulcer effect. Our data are in favor for a beneficial effect for topically applied ginseng on the gastric mucosa.
The Study of Hepatic Antioxidative Enzyme Activity and Eletrophoresis in Mice After Treatment with Paraquat and/(or) Ginseng Saponins
Journal of Ginseng Research, volume 25, issue 4, 2001, Pages 150~155
This study examined effects of the active ingredients from ginseng on paraquat(PQ) toxitity. Mice were given PQ(25mg/kg, ip) and then they were given total saponins (TS; 5mg/kg, orally), protopanaxadiol (PD; 5mg/kg, orally) and protopanaxatriol(PT; 5mg/kg, orally) per day for periods of 1,3 & 7 days. We measured the activities of superoxide dismutase (SOD), electrophoretic isozyme band, catalase (CAT) were compared in the liver of mouse that dose with PQ and/or TS, PD and PT. The activities of SOD, CAT were generally higher in PQ+PD group than others groups. Especially the activity of SOD was the highest in PQ+PD group than others groups. SOD isozyme separated into three bands by electrophoresis. One band was located to near the anode side and two bands were cathode side. As the results of treated with KCN, we were confiremed that the Cu, Zn-SOD was located to near the anode side but the Mn-SOD were cathode side. Our results suggested that an antioxidant effect of ginseng saponins elevated a protection ability to an oxidative damage by direct action of SOD, CAT and reinforced the synthetic ability of endogenous antioxidant material in living organism. Particularly, PD was a effective antioxidant compared with others.
Effects of Polyacetylenes in Ginseng on Activity of Enzymes Related to Post-translational Modification of Ras Protein and Effects of Petroleum Ether Extract of Ginseng on Progression of Cell Cycle
Journal of Ginseng Research, volume 25, issue 4, 2001, Pages 156~161
We investigated the effects of polyacetylenes of ginseng on farnesyl protein transferase (FPTase) and carboxyl methyl transferase (CMTase) activities related to post-translational modification of Ras protein. We also investigated the effect of petroleum ether extract (PEE) of ginseng on progression of cell cycle. FPTase activity was respectively inhibited 16.2% by 10mM panaxynol and 21.3% by 10mM panaxydol, whereas CMTase activity was not inhibited by panaxynol or panaxydol. Treatment of PEE significantly reduced the numbers and size of human colon cancer cell (HT-29) and human liver cancer cell(HepG2) cultured, respectively. To investigate the mechanism of growth inhibition by PEE of ginseng, we analyzed the cell cycle progressions of PT-29 and HepG2 cells, respectively. We found that PEE significantly inhibited progression of cell cycle from G1 to S phase. These results suggest that anticancer effects of PEE were derived from the arrest of G1 phase in cell cycle progression.
Hypocholesterolemic Effect of Panaxydol in High Cholesterol Diet Fed Rats and Mice
Journal of Ginseng Research, volume 25, issue 4, 2001, Pages 162~166
The effect of petroleum ether soluble fraction (PESF) and panaxydol extracted from red ginseng on serum cholesterol levels was examined in rats and mice fed on a high cholesterol diet. When 2% cholesterol diet containing PESF (800mg/kg diet) or panaxydol (100mg/kg diet) was fed to mice for two weeks, total cholesterol and LDL-cholesterol in the serum were significantly decreased in PESF and panaxydol treated group. Panaxydol (5, 10mg/kg b.w./day) was administered for 3 consecutive days by intraperitoneal injection in rats fed on 1% cholesterol diet. Serum total cholesterol, triglyceride and LDL-cholesterol levels of panaxydol administered group (5 mg/kg b.w./day) were decreased by 55%, 33% and 67% compared with those of the control group, respectively. However, a significant increase of serum HDL-cholesterol was observed on panaxydol administered group. Furthermore, hepatic cholestrol levels was significantly decreased in panaxydol administered group. These results suggest that panaxydol could protect hypercholesterolemia.
Optimum Chilling Terms for Germination of the Dehisced Ginseng(Panax ginseng C. A. Meyer) Seed
Journal of Ginseng Research, volume 25, issue 4, 2001, Pages 167~170
Experiments were conducted to study the optimum chilling period for breaking physiological dormancy of dehisced ginseng(Panax ginseng C. A. Meyer) seed. Embryo of ginseng seed is too small to be noticed with naked eyed on harvesting time. Embryo grew to half size of endosperm after seeds were stratified for 3 months. It takes 6 months for this embryo to reach the size enough for germination. And it grew faster indoors than outdoors. Dehisced ginseng seed with full-size embryo did not germinate at room temperature and required chilling treatment for 75days in outdoors and 90 days in cold chamber. While seed receiving sufficient chilling treatment were left to be in room temperature, the chilling effect decreased remarkably.
Strategies for Channel Innovation of True Korea Ginseng Distribution Using Genuine Guarantee System
Journal of Ginseng Research, volume 25, issue 4, 2001, Pages 171~177
Lately, the Korean ginseng was confronted with the sale crisis in world markets from the various circumstance. One of important difficulties is overspreading of Korean ginseng imitative in foreign markets. In Korean markets also, chinese ginseng was imported illegally and manufactured as Korean ginseng, which was resulted inthe damage of Korean ginseng brand. The most essential problem is misunderstanding of Korean ginseng 。 s information in the foreigner. In this paper, we developed a genuine guarantee system to identify the true Korean ginseng through internet and geographic cording system of Korean ginseng products. This system can be applied to the enforcement of Korean ginseng sale to international markets.
