  • To investigate changes of dry weight, C/N ratio, carbohydrate, ratein and nucleic acids in the barks of the hardwood cutting of mulberry plants, the barks of the hardwood cutting were taken every 10days from the cutting day to 40days after cutting. Results were summarized as follows : Growth of shoot and root in Keomseolppong (Morus bimbycis KoIDZ.) after cutting was better than that in kaeryangppon (Morus alba L.) and Daeryugppong(Morus Lhou(SER.) KoIDZ.). Dry weight in the barks of the hardwood cutting decreased up to 40days after cutting (decrease percentage of dry weight : about 14%) and Keomiseolppong showed the highest decrease precentage of dry weight. Change of C/N ratio decreased in the initiation, whereas that from 10days after cutting increased with the growth of new shoot, C/N ratio was the highest in Keomseolppong and the lowest in Kaeryangppong. Total sugar showed decreasing tendency up to 40 days after cutting the increase from 10 days to 20 days. Reducing sugar increased in the frist 20days, followed gradually decrease up to 40 days after cutting Starch levels decreased up to 40 days. Change in the content of starch closely paralleled to that of dry weight of bark of the hardwood cutting. Content of total sugar and starch in Keomseolppong was the highest, and was consumed more than that in the rest of varieties. Crude protein and soluble protein increased up to 10 days after cutting, followed decrease up to 40 days. Protein content of Keomseolppong was smaller than that in the rest of varieties. RNA content showed the same tendency with that of protein content, but Keomseolppong showed always the highest. Content of DNA did not show any change and difference among three varieties.

  • We bred a mulberry cultivar named Suhyang through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test was carried out at four places (Suwon, Kongju, Wanju and Jinju) for six years from 2007 to 2012. This is belonging to (Morus alba L.) crossed between Josaenghongpisang (Morus alba L.) and Kaeryang (Morus alba L.) among mulberry genetic resources preserved in Suwon. Suhyang was high yielding cultivar in fruit productivity by 12% compared to control cultivar 'Chungil (Morus alba L.)' for four years. Although Suhyang was higher in sugar content of mulberry fruits, it was bigger than that of 'Chungil'. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

  • Male Sprague-Dawley rats received either a cholesterol diet (Control group) or cholesterol diets supplemented with the water-extracted of leaves from Morus alba (MA group) or Cudrania tricuspidata (CT group) at the level of 1% for 2 weeks. The concentration of serum triglyceride was significantly lower in the CT group and was also lower in the MA group than in the control group. The liver cholesterol concentration was significantly lower in the MA group than in the control group, but not significantly different between the CT group and the control group. The concentration of phospholipid in serum was an increasing tendency in the MA group and was a decreasing tendency in the CT group compared to that in the control group. Body weight gain, food intake, food efficiency, the concentrations of triglyceride and phospholipid in liver, and the total cholesterol, HDL-cholesterol and glucose in serum were not significantly different among dietary groups. These results suggest that the water-extracted from leaves of Morus alba and Cudrania tricuspidata exerts a hypotriglycerolemic effect in the cholesterol-fed rats.

  • Morus alba extract(MAE) was tested for its ability to inhibit alloxan induced lipidperoxidation. Lipid peroxide contents in serum, liver, kidney and heart were measured by the TBA method. ICR mice receiving alloxan at a dose of 6mg/kg intraperitoneally after a 24hrs starvation showed significantly increased lipid peroxide contents as compared to untreated control. Lipid peroxide contents in serum, liver, kidney of alloxan-diabetic mice were decreased by the treatment of MAE at the dose of 50mg/kg, 100mg/kg for 7 days.

  • Potential antinumor activity of sixteen Korean medicinal plants was tested against leukemia SN 36, murine tomor model. Survival studies by measuring life span indicated that Morus alba (Moraceae), Verbascum phlomoides (Scrophulariaceae), Curcuma longa (Zingbieraceae), Torilis japonica (Umbelliferae), Bupleurum falcatum (Umbelliferae) and Codonopsis pilosula (Campanulaceae) exhibited significant antitumor activity with the dose-schedule employed in the experiment. Methanol (70%) extracts of Platycodon gradiflorum (Campanulaceae), Bupleurum longeradiatum (Umbelliferae) and Asiasarum sieboldii (Aristolochiaceae) showed rather potent toxicity.

  • Objectives : To clarify the possible effect of Lycium chinese Mill (LC)., Morus alba L (MA)., and Lycium chinese Mill. +Morus alba L. (LC+MA), we have examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : Female Balb/c mice (5weeks) were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2ml alum-precipitated Ag containing $100{\mu}g$ of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, LC, MA, and LC+MA (500 mg/kg) were orally administered 3 times per a week for 8 weeks. Results : The suppressive effect of LC, MA, and LC+MA were demonstrated by the accumulation of eosinophills into airways, with the reduction of eosinophil, total lung leukocytes numbers. These were correlated with the marked reduction of IL-5, IL-13 and IL-4 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. LC, MA, and LC+MA decreased eosinophil CCR3 expression and CD11b expression in lung cells. Conclusions : These results indicate that LC, MA, and LC+MA have high inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, eosinophil CCR3 expression and CD11b expression, and the increase of IFN-${\gamma}$ production in BALF seem to contribute to this effect. Hence, the results indicated that LC, MA, and LC+MA could act as a immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

  • In our country there are five species of Morus genus including Morus alba L.. Also their varieties and hybrids are distributed so much. In sucession of previous report we collected control and marketing specimens of Mori Cortex Radicis, comparative experiments were pharmacognostically carried out to identify the control specimen by the differences of external and internal morphology. It was difficult to identify marketing specimens by external morphology, because they are similar in spite of conparating with control specimen which the origin is definite. In internal morphology, medullary ray is developed near the cambium to primary bark in control specimen A(Morus alba series) and C(M. Lhou series), but less developed in B(M. bombycis series). The difference of these three series was observed. The thickness of cork layer is almost the same($7{\sim}12$ layers) in A and C series, but B is thin layer and sample E(that on the market) is generally more thick and has a stick cork cell. The kinds of starch, Ca-oxalate and latex, cell centents were same, but it was easy to identify them by the differences of their distribution. The bast fibre of D(wild specimen) and E were light lignified, latex tube of A and C series was richer distributed than others. These results show that the origin of Mori Cortex Radicis on the market can be appreciated in four groups of Korean Morus genus which are M. alba, M. bambycis, M. Lhou series and the others.
