The purpose of this study was designed to observe the effects of the feeding Prunus persica Batsch var. davidiana Max. extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride(TG), phospholipid(PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (groups BCG (cholesterol+water), BCPG (cholesterol+ Prunus persica 5.0 g% extract) than those in the control group (group BG, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remarkably lower in the group BCPG than those in the group BCG. In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Prunus persica 5.0 g% extract administration group was higher percentage than in the group BCG. The activities of aspartate aminotransferase (AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Prunus persica 5.0 g% extract administration group(group BCPG) than in the cholesterol diet group(group BCG). From the above research, Prunus persica Batsch var. davidiana Max. were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Prunus persica Batsch var. davidiana Max. was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

Almonds are one of the oldest sources of food and oil for man as used the ice cream, candy, roast, salting, chocolate, breads, backed, cookies, and flavoring ect. So, we wish to plant Almond in our country at the most parts of mountains. In this purpose we must be find out of both root stock of more compatibility and new techniques of grafting was rather simples as compared with the many steps of machinary involved today. This investigation has been carried out to reveral compatibility and practical controls of environment effectives involved in the occurence of each difference combination results in interspecific grafting of Almonds on the root stock of Prunus mandshurica and Prunus persica as materials during the 9 months period from March to November in 1978. With these selected scions were 4 varieties of Almond employing as the Hal1's hardy, Nonpareil, and Thompson grafted in the polyethylene green house with almost identical provision made for effective controls of automatical supplying to heating and mistsprayers as the $22{\sim}25^{\circ}C$ of temperature and 70~90% humidity. Following results have been obtained. Those environmental controls were more effective and practical to grafting unions and success by means veneer-grafting at the green house. 1. Hall's hardy Almond grafted on the root stock of Prunus persica was more compatibility than Prunus mandshurica. 2. The survival percentages as follows of the 95.33% of Hall's hardy/Prunus persica and 92.66% of Hall's hardy/Prunus mandshurica. And those were no significant between root stock of both species. 3. The 3 varieties of sweet Almond grafted on the root stock of P. mandshurica. And those were no significant between root stock of both species. 4. And the survival percentages as fellows. Thompson 92.66%, Nonpareil 90.66% and Kapareil 89.33% those grafted on the root stock of Prunus persica. 5. And then the survival percentage of interspecific grafts on the root Prunus mandshurica as follows of the materials of Thompson 89.66%, Nonpareil 87%, Kapareil 85%. 6. The analysis of variance were no significant among the interactions between 3 varieties Almond and 2 species of root stock plants. 7. And the growth of interspecific grafts of the high 161cm, diameter 12.3mm and length of roots 21.5cm growth as the Hall's hardy Almond grafted on the root stock of Prunus persica. 8. The root stock plants of Prunus mandshurica more effected to 6~8 days early developed leafing of scions and dark green colour than the Prunus persica. 9. The identical provision of automatic systems was more effective to graft unions and grafting process. 10.

The purpose of this study was designed to observe the effects of the Prunus persica Batsch var. davidiana Max. hot-water extract on the improvement of the glucide and lipid metabolism in the serum of streptozotocin (STZ, 55, mg/kg B.W., I.P. injection)-induced diabetic rats(S.D. strain, male) fed the experimental diets for 5 weeks. Electrolyte(Na, K, Cl) concentration in serum were fairly reduced in the group BSP(basal diet+STZ+Prunus persica $5.0g\%$ extract) than in the STZ(I.P.)-induced diabetic rats group(group BSW, basal diet+STZ(I.P.)+water). Although there was no significant difference among the groups. Concentrations of free fatty acid and lipid peroxide in serum were significantly higher in the STZ-induced diabetic group(group BSW) and STZ+Prunus persica $5.0;g\%$ extract group(group BSP) than those in the control group(group BW, basal diet+water). However, the concentrations of free fatty acid and lipid peroxide in serum were remarkably reduced in the group BSP than those in the group BSW, The activity of creatine phophokinase In serum was significantly lower in the group BSP than in the group BSW However, the activity of LCAT in serum was increased in the group BSP(Prunus persica $5.0\;g\%$ hot-water extract administration group) than in the STZ-induced diabetic group(group BSW). The above results shows that Prunus persica Batsch var. davidiana Max. were effective on the improvement of the glucide and lipid metabolism in serum of streptozotocin-induced diabetic rats.

This study was designed to analyze the effects of methanol extracts and solvent fractions of the young branch of Prunus persica on scavenging activity of ROS, RNS and inhibiting activity of oxidative modification in human LDL induced by copper ion or free radical generator. The scavenging capacities of the fractions on DPPH radical, superoxide radical, nitric oxide and peroxynitrite were exhibited the highest in ethylacetate fraction, followed by butanol fraction. In the copper-induced LDL oxidative modification system, the highest antioxidant activity was revealed in ethylacetate fraction, and butanol fraction exhibited a similar activity. However, solvent fractions of the young branch of Prunus persica showed a relatively low antioxidant activity in the AAPH-mediated LDL oxidation. In addition, ethylacetate and butanol fractions also inhibited the copper-mediated LDL oxidation in the REM assay, which was comparable to that of the positive controls, including EDTA, ascorbic acid and BHT. Futhermore, a content of total phenolics in these two fractions was higher than that of the other fractions. These results indicated that ethylacetate and butanol fractions of the young branch of Prunus persica were useful for the prevention of the free radical- or metal ion-induced oxidative damages.

The solvent extracts of Prunus persica Flos were investigated for the activities of anti-oxidant and anti-inflammation to apply as a functional ingredient for cosmetic products. The electron donating ability of both ethanol (PPE) or acetone (PPA) extracts of P. persica Flos was above 90.0% at the concentration of 500ppm. The superoxide dismutase (SOD)-like activity of P. persica Flos extracts (PPE, PPA) were approximately 40.0% at 1,000 ppm. The xanthine oxidase inhibitory effect of P. persica Flos extracts (PPE, PPA) was approximately 30.0% at 1,000 ppm and equivalent to that of ascorbic acid. Hyaluronidase inhibition activity related to the anti-inflammation effect was 35.0% with the treatment of P. persica Flos extracts (PPW, PPE, PPA) at 1,000 ppm, respectively. In the experiment of anti-inflammation effect, P. persica Flos extracts (PPW, PPE, PPA) inhibited the generation of nitric oxide. In the antimicrobial activity test against the human skin-resident microflora such as Staphylococcus epidermidis and Propionibacterium acnes, a clear zone was identified from 4mg/disc in P. persica Flos (PPE) extract.

In this study, the compounds of Prunus persica Flos were extracted with 70.0% acetone and were purified using a sephadex-LH-20 column chromatography. As a result, eight fractions were isolated. For whitening effects, the tyrosinase inhibitory activity was determined to be 92.2% in Fr.-8 isolated from P. persica Flos at 1.000 ppm. The melanoma cell-originated tyrosinase inhibitory effect of Fr.-8 from P. persica Flos was approximately 63.4% at 100 ppm. The inhibitory activity on melanin synthesis by Fr.-8 isolated from P. persica Flos was about 71.7% at 100 ppm concentration. For anti-wrinkling effects, the elastase inhibition activities by Fr.-5, 7 isolated from P. persica Flos were around 71.4 and 74.5% respectively at 1,000 ppm. The collagenase inhibition activity and collagen synthesis by Fr.-8 isolated from P. persica Flos was about 80.0% at 100 ppm. All these findings suggested that the fractions of P. persica Flos have great potential as cosmeceutical ingredients with whitening and anti-wrinkling effects.

Paeonia Suffruticosa and Prunus Persica have been used as oriental medicine for removal of fever, alleviation of pain, an anti-phlogistic effect and removal of extravasated blood. However, it has been never shown the effects of these herbal medicines on anti-inflammatory processes. This experiment was performed to show how these herbs could act as anti-inflammatory medicines at cellular level. Anti-inflammation effects of water extracts from Paeonia Suffruticosa and Prunus Persica as well as their mixture have been investigated, and the results were follows; 1) each extract slightly suppressed the expression and production of inflammatory mediators and enzymes such as NO, iNOS, IL-$1{\beta}$, and TNF-$\alpha$ in lipopolysaccharid(LPS)-stimulated RAW264.7 cells and mouse primary peritoneal macrophages in a dose-dependent manner. These suppressive effects, however, were synergistically increased by their mixture. 2) Each extract of Paeonia Suffruticosa and Prunus Persica insignificantly suppressed the activation and activity of NF-${\kappa}B$ in LPS-stimulated RAW264.7 cells, which controls the expression of inflammatory mediators such as NO, iNOS, IL-$1{\beta}$, and TNF-$\alpha$. However, extract mixture of Paeonia Suffruticosa and Prunus Persica suppressed effectively the activation and activity of NF-${\kappa}B$. 3) Each of Paeonia Suffruticosa and Prunus Persica induced translocation of NF-${\kappa}B$ to the nucleus from the cytosol and DNA-binding activity of nuclear NF-${\kappa}B$ in LPS-activated RAW264.7 cells. The extract mixture of Paeonia Suffruticosa and Prunus Persica showed more significant suppression of the NF-${\kappa}B$ translocation and its DNA-binding activity, as compared to those of the each extract. These results suggest that the extract mixture of Paeonia Suffruticosa and Prunus Persica may affect different control mechanisms for NF-${\kappa}B$ activation and the expression and production of NF-${\kappa}B$-dependent inflammatory mediators, indicating that this extract mixture may be useful for treatment of inflammatory diseases.

This study was performed to observe the effects of the feeding Prunus persica Batsch var davidiana Max. extract on the improvement of the free fatty acid, creatine phosphokinase and lecithin cholesterol acyltransferase(LCAT) activities in the serum of dietary hypercholesterolemic rats(S. D. strain, male) fed the experimental diets for. 5 weeks. Concentration of electrolyte(Na, K, Cl) in serum were fairly reduced in the group BCP(basal diet + cholesterol + Prunus persica, $5.0\;g\%$ extract) than in the group BCW(basal diet + cholesterol + water). However, no significance was found in the effect of an electrolyte concentration among the groups. Concentrations of free fatty acid, lipid peroxide and creatine phosphokinase activity in serum were significantly higher in the cholesterol administration groups(group BCW, BCP) than those in the control group(group BW, basal diet + water). However, concentrations of free fatty acid, lipid peroxide and creatine phosphokinase activity in serum were remarkably lower in the group BCP than those in the group BCW The LCAT activity in serum was increased in the Prunus persica $5.0g\%$ extract administration group(group BCP) than in the cholesterol of diet group(group BCW). From these results, the Prunus persica Batsch var davidiana Max. extracts were found to be effective on the improvement of the lipid compositions in serum of dietary hypercholesterolemic rats.

To select fruit trees suitable for shaded urban garden with Elaeagnus umbellata var. coreana, Malus domestica 'Alps Otome', Malus domestica 'Fujii', Prunus mume, Prunus persica for. persica, Rubus fructicosus, and Vaccinium corymbosum 'Reka', leaf growth in response to different light was investigated two years after 35% shade treatment. Leaf area of E. umbellata var. coreana, M. domestica 'Alps Otome', P. mume, P. persica for. persica, and V. corymbosum 'Reka' increased in shading. Fresh weight of leaves make inconsistent response to shading in every species but dry weight of E. umbellata var. coreana and P. persica for. persica showed the highest 150% and 148%, increment, respectively. Althought leaf water content of E. umbellata var. coreana decreased in shading, there is no difference in P. persica for. persica. Chlorophyll value of E. umbellata var. coreana and P. persica for. persica that showed higher than any other species is correlated with dark leaf green. Compared to specific leaf weight of E. umbellata var. coreana, P. persica for. persica, and V. corymbosum 'Reka' showed lower than any other species in shading, that of M. domestica 'Fujii', and R. fructicosus increased in reverse. These results indicate that E. umbellata var. coreana and P. persica for. persica that showed high value in several invesetigaton items are suitable for shady urban condition considering leaf growth in response to shading.
