The effect of ethanol extracts of Gilkyung(Platicodi Radix, Platicodongrandiflorum A, DC), Onji(Polygalae Radix, Polygala tennuifolia Willdenow) and Deoduk(Codonopsis lanceolate Radix, Codonopsis lanceolata) on expectorant activity of rat trachea was investigated. Following treatment of 50% ethanol extract of these medicinal plants (25 mg/rat), the content of neurotransmitters such as acetylcholine and histamine in tissue was significantly increased. The secretions of acid glycoproteins and the artificially injected phenol red were also increased. However, there was no significant difference except Onji From the histological study through periodic acid Schiff and alcian blue stain, the thickness of inner membrane of acinar glands and the stained glycoproteins on surface of epithelium and on the glands were observed in all the rats trachea treated with extract of medicinal plants. In vitro, the viscosity of mucin solution was slightly decreased with an addition of the extracts. Onji showed the most effective expectorant activity among them at the identical conditions. The mechanism of expectorant activity of these medicinal plants seems to be due to stimulation of secretion and changes of rheological properties of mucus.

Ginseng(Panax ginseng C. A. Meyer) is important medicinal plant but requires 4-year cultivation for root harvest because of slow growth. In contrast, ginseng hairy roots induced by introducing Ri-plasmid of Agrobacterium rhizogenes into genomic DNA of plant cells show vigorous growth, and the hairy roots produce the same or more saponins than natural ginseng roots. Therefore, hairy roots can be used for commercial purposes. The present study was carried out to induce hairy roots with both active growth and high saponin contents. Numerous hairy roots of Panax ginseng were obtained after root disks of three-year old roots were infected with Agrobacterium rhizogenes R1000 A4T in dark condition after one month of culture. About 3 hundred lines of hairy roots were selected according as morphological characters on medium with carbenicillin. After pre-selection of fifteen lines of hairy roots with active growth, KGHR-l and KGHR-8 lines were finally selected which had characters of high content of ginsenoside-Rd and ginsenoside-Re, respectively. The optimum growth of hairy roots was achieved in the culture of 1/2 MS liquid medium in dark (22 $^{\circ}C$) under 60 rpm gyratory shaking. Hairy roots grew well in 5L Erlenmeyer flasks, lL roller drums, 10L jar-fermenters, and especially in 20L air-lift culture vessels.

A chronical intake of Substantial amount of alcohol would disrupt anormal function of liver if not develop liver diseases in relatively short period. In order to out whether ginseng or ginseng plus high protein diet have any protective effects on the liver of chronical alcoholist from developing malfunction enzymatic activities of both glutamic-pyruvic and glutamic-oxaloacetic transaminases were measured on serum of rats maintained with basal low protein diet, basal diet plus 1 percent ginseng and high protein (40%) plus 1 percent ginseng and administered intraperitoneally with a Constant amount of ethanol either periodically or chronically. It was found that, unlike human subject GOT content was exceedingly high and significant difference was found either among treatment or among sexes thus indicating that either ginseng intake or high protein diet plus ginseng has a protective effect on the liver function of ethanol treated rats. From these results, it was suggested that the dietary ginseng might, have a protective effect on the alcohol hepatic disturbance. As one of probable mechanisms for the characteristic pharmacological activity, it was considered that a secondary action of the saponin of the dietary ginseng would result in the anti-inflammatory through the stimulation of de nove synthesis of certain functional proteins in hepatic organs.

Quality stability of the herb pill coated with edible oils containing rosemary was investigated. Herb pills were made of herb powders such as Panax ginseng, Cinnamomum cassia, Lycium chinense, Zyzyphus jujuba and Zingiber officinale. Rapeseed oil and lubriol were used as edible coating oil. After herb pills coated with edible oils with or without rosemary were stored at $40^{\circ}C$ for 180 days, the microbial viable cell counts and peroxide values(POV) of the herb pill were investigated. After 180 day storage, POVs of herb pills with only rapeseed oil or lubriol were 0.51 and 0.49 meq/kg, respectively. However, when rosemary was added in herb pills the POVs were decreased to 0.30 and 0.39 meq/kg, respectively. The addition of rosemary to the rapeseed oil and lubriol tended to decrease the microbial viable cell counts of the herb pill. The microbial viable cell counts of rapeseed oil and lubriol were 940 and 820CFU/g, respectively after 180 days of storage. However, these levels were suppressed to 720 and 640CFU/g by the resemary addition. On the other hand, the ginseng saponin content of herb pills was not affected by the rosemary addition during storage.

In order to investigate the inferior factor of red ginseng quality, the contents of various chemical components, physico-chemical properties and arrangement state of ginseng cells were observed. Contents of total reducing sugar, reducing sugar, crude protein, crude fibre and specific gravity of inside white part of red ginseng were less than those of normal part. But differences in content of crude saponin, HPLC pattern of ginsenosides and reducing ability for DP P H(1,1-dipheny 1-2-picrylhydrazyl) between normal and inside white part of red ginseng were not found. The optical density of 1 water extract of normal part of red ginseng did not differ from that of inside white 1 part of red ginseng, but the visible and UV absorbance of acid hydrolyzate of normal red ginseng showed higher than those of inside white part of red ginseng. The differences in the internal color and tissue of normal and inside white part of red ginseng were easily found with naked eye, and by the microscopic fractography, the orangement state of ginseng cell in the inside white part of red ginseng was less dense than that in normal red ginseng.

Black ginseng and white ginseng were extracted with 80% ethanol and evaluated for relative ginsenoside composition, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities, and antioxidant properties. As analyzed by HPLC, black ginseng contained a greater proportion of ginsenoside $Rg_3$ compared to white ginseng. White ginseng was characterized by undetectable ginsenoside $Rg_3$ but it contained more total ginsenosides than black ginseng. Black ginseng extract exhibited higher (p<0.05) free radical-scavenging activity, as well as higher antioxidant activities than white ginseng against 2,2-diphenyl-1-picryl-hydrazyl, superoxide dismutase, and xanthine oxidase, despite the fact that the total saponin content was higher in white ginseng than black ginseng. In addition, the black ginseng extract displayed greater AChE and BChE inhibitory activities. These results suggest that black ginseng has stronger effects on anti-oxidation and AChE and BChE inhibition than white ginseng.

We attempted in this study to understand the hypoglycemic action of the fat soluble fraction of red ginseng roots in streptozotocin injected diabetic rats, through its actions on several enzymes relating to carbohydrate metabolism of the 1eve1 to compare with those of ginsenosides in streptozotocin injected diabetic rats. It was realized that the increased level of glucose, ketone bodies, lactate, nonesterified fatty acids and triacylglycerol in blood was significantly decreased and the decreased liver glycogen content of streptozotocin injected rats were appreciably moderated by intraperitoneal injection of the fat soluble fraction of red ginseng roots as shown in the saponin injected diabetic rats. The deceased activities of liver enzymes relating to carbohydrate metabolism such as phosphofructokinase, glucokinase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase and acetyl CoA carboxylase of streptozotocin induced diabetic rats were also sufficiently modified by the intraperitoneal injection of the above fat soluble fraction as shown in the ginsenoside injected streptozotocin induced rats.

The results that the effect of 6 detergents on the structural changes and biochemical composition of bacterial membrane of Escherichia coli and Bacillus cereus are as follows ; 1. Population growth of the bacteria was increased in case of the treatment with palmitoyl carnitine and sodium deoxy cholate but was increased in case of the treatment with palmitoyl carnitine and sodium deoxy cholate but was decreased by sodium dodecyl sulfate and palmitoyl choline, in E.coli and was decreased by palmitoyl carnitine and palmitoyl choline at the low concentration, in B. cereus. 2. The electron micrograph showed that cell wall lysis or cell collapse were observed in the treatment of sodium dodecyl sulfate and palmitoyl choline, and also cell wall was condensed by triton X-100 and sodium deoxy cholate, in E.coli. And in B. cereus, endospore formation of the bacteria was stimulated by palmitoyl choline, and cell lysis or structural changes of the membrane were observed in the treatment of sodium dodecyl sulfate, sodium cholate, and triton X-100, respectively. 3. As to the effect of detergent on the biochemical composition of biomembrane, the content of carnitine, in E.coli, and B.cereus, the content of structural protein and phospholipid were decreased by treatment of sodium dodecyl sulfate and structural protein was denatured by palmitoyl choline. 4. The profile of membrane protein revealed that the bacterial membrane were composed of various proteins. By dint of this result, some of membrane proteins were solubilized or changed to small molecules by the treatment of sodium dodecyl sulfate and palmitoyl choline, in E.coli and membrane protein of the biomembrane by treatment of sodium dodecyl sulfate, sodium deoxy cholate, palmitoyl choline, and palmitoyl carnitine were confirmed to be different profile as compared with those of the control, in B. cereus. Therefore, it is suggested that sodium dfodecyl sulfate and palmitoyl choline soulbilized biomembranes or inhibited membrane transport and that palmitoyl carnitine and sodium deoxy cholate were used as an energy source or stimulating the membrane transport, in E.coli. And, it is suggested that all of detergents were inhibited biomembrane synthesis, expet saponin, in B.cereus.

Background: This study determined the effects of mulching, an environment friendly organic cultivation method, on antioxidant compound contents and growth in Codonopsis lanceolata, commonly known as Deodeok. Methods and Results: C. lanceolata was treated by mulching with several different methods (a non-woven fabric, biodegradable film, or rice husks) and also treated with hand weeding. A non-treatment plot was used as a control. The growth and levels of weed control in C. lanceolata were better in plants cultivated under mulching treatments (non-woven fabric, biodegradable film, and rice husks) than in those under non-mulching treatments (hand weeding and non-treatment). The contents of antioxidant compounds, such as total flavonoids, phenolics, and anthocyanins, were highest under the biodegradable film treatment, followed by the non-woven fabric treatment, rice husks treatment hand weeding, and non-treatment. There were identifiable differences in DPPH and ABTS activity in comparison to antioxidant compound content by solvent fractions. Mulching treatments resulted in higher DPPH scavenging activity in water and ethyl ether fractions and ABTS scavenging activity in n-butanol fractions than in other fractions, as opposed to hand weeding and non-treatment groups, although total activity of DPPH and ABTS did not increase with mulching treatments. Conclusions: Mulching C. lanceolata with biodegradable film and non-woven fabric is an effective method for improving plant growth and inhibiting the occurrence of weeds as well as for increasing antioxidant compound content and altering antioxidant activity.
