Lee,Jun-Ki,Hyun,Sang-Ki,Lee,Sang-Sun,Chai,Jung-Ki 한국자원식물학회 2002 Plant Resources Vol.5 No.1
Twenty-three plants of Japanese apricot (Prunus mume) were collected from several sites around Mountains JIRI in Korea. Japanese apricots having the different morphological features were evenly distributed in the groups made from the cluster analysis, indicating no geographic distributions but artificial vegetations in Korea. Japanese apricots were, as based on the PCR-RAPD techniques, clustered into the three groups; a group (prototype) having the five white petals with the five red sepals, a group (green type) having the five white petals with the five green sepals, and a group (hybrid type) having the more than five red petals with various colored sepals. The prototype apricots showed higher toxicities than other type apricot against bacteria and production of less compounds in TLC plates. The polypetal types of Japanes apricot were related to those of p. armebiaca in the characteristics of seed (the ruggedness), but also to be closed to those of p. armebiaca in PCR-RAPD analysis. The cluster analysis of the twenty three apricots and its related species calculated from the two primers were shown to distinguish relationships of cultivars within species, or of individual plants within cultivars, but also to display the two overlapping bands resulted from PCR-RAPD technique.

The purpose of this study was to investigate the short term effects of HMB Supplementation on total power and fatigue factor(Lactate, LDH, CK). Eleven volunteers (placebo group 5, HMB group 6) from Uuniversity participated in this study. The measurement methods were used 30-s wingate test(Maximum exercise during 15s and activity rest 45s ?5set). The data of measurement was analyzed by using SPSS-PC Window program. paired t-test was performed for the statistics. The level of significant was set at P<0.05. The main findings of this study were follows: 1. The concentration of Lactate in placebo group was significant lower than HMB group. 2. Blood LDH was no significant difference in two group. 3. Blood CK was no significant difference in two group. 4. Total power was statistically higher in a HMB group than placebo group.

Backgrounds : The expression of the MDR-1(multidrug resistance)encoded P-170 glycoprotein(p-170)and CD34 have been well known to be associated with drug resistance in AML(acute myelogenous leukemia). P-170 and CD34 expression in AML have been reported as unfavorble prognostic parameters separately. Methods : P-170 glycoprotein expression was analyzed in correlation with CD34 expression and clinical response in 15 consecutive patients with de novo acute myelgenous leukemia (AML). They were measured with flow cytometry after direct and indirect immunofluorescence staining simultaneously. Results : 1) The positive rate of P-glycoprotein and CD34 were in two of 15 patients(13%), seven of 15 patients(46%), respectively. 2) One of two P-170 positive patients as compared with 7 of 13 P-170 negative patients achieved a complete remission(CR), which showed no clinical significant difference. 3) There was no significant correlation between P-glycoprotein and CD34 expression(r=0.29, p=0.28). 4) In de novo acute myelogenous leukemia, there was no case which expressed both P-170 and CD34 simultaneously. 5) P-glycoprotein and CD34 were not expressed in acute promyelocytic leukemia group. 6) Cytogenetic abnormalities did not show any significant difference in the rate of P-glycoprotein expression, CD34 expression and complete remission. Conclusion : CD34 and P-glycoprotein in acute myelogenous leukemia were independent parameter in this study. Further investigations are warranted for clinical implication.

An Ac-type Plasma Display Panel (PDP) operating with Ne-Ar(0.1%) Penning mixture gas is fabicated. The characterics of the panel with electrodes covered with thin and thick dielectric layers are studied. The brightness of the Neon-orange light emitted by the panel measured as function of applied voltage and frequency. As an application, a graphic display system equipped with PDP showing still and moving pictures is made.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.

A 73-days rearing trial was conducted to investigate the effects of different photoperiod on growth and survival rate of juvenile abalone (Nordotis discus hannai). Survival rate was not significantly affected by different photoperiod condition (P>0.05). Growth rates on shell length and shell breadth of 12L/12D, 18L/6D and 24L/0D groups were higher than those of control (P<0.05), but growth on shell length, shell breadth and shell height of 0L/24D group was lower than those of control (P<0.05). Soft body weight and fatness index of abalone reared 24L/0D condition was greater than all of experimental groups. The results suggest that long photoperiod can improve weight gain of abalone
