The objective of this study was to understand the conservation of gene resources and provide information for mass selection of winter bud characters among the selected populations of Kalopanax septemlobus Koidz using analysis of variance(ANOVA) tests. The obtained results are shown below; 1. Ten populations of K. septemlobus were selected for the study of the variation of winter bud characters in Korea. The results of the analysis of variance(ANOVA) tests shows that there were statistically significant differences in all of the winter bud characters among those populations. 2. Correlation analysis shows that width between Height and DBH(Diameter at breast height) characters have negative relationship with all of the characters, as ABL(Apical branch length), ABW(Apical branch width), AWBL(Apical branch winter bud length), AWBW(Apical branch winter bud width), ABT(Apical branch No. of thorns), ABLB(Apical branch No. of lateral bud) and LBL(Lateral branch length), LBW(Lateral branch width), LBT(Lateral branch No. of thorns), LBLB(Lateral branch No. of lateral bud). 3. The result of principal component analysis(PCA) for winter buds showed that the first principal components(PC s) to the fourth principal component explains about 78% of the total variation. The first principal component(PC) was correlated with AWBW, LWBW, and LBL and the ratio of ABL/ABW and LBL/LBW out of 16 winter bud characters. The second principal component correlated with ABL, ABW, ABLB, LWBL(Lateral branch winter bud length), and LBW and the ratio of AWBL/AWBW. The third principal component correlated with ABL, ABW, LWBL, LBL, and the ratio of LBL/LBW. The fourth principal component correlated with LBL and the ratio of LWBL/LWBW(Lateral branch winter bud width), LBL/LBW. Therefore, these characters were important to analysis of the variation for winter bud characters among selected populations of K. septemlobus in Korea. 4. Cluster analysis using the average linkage method based on 10 selected populations for the 16 winter bud characters of K. septemlobus in Korea showed a clustering into two groups by level of distance 1.1(Fig. 3). As can be seen in Fig. 3, Group I consisted of three areas(Mt. Sori, Mt. Balwang and Mt. Worak) and Group Ⅱ contisted of seven areas(Suwon, Mt. Chuwang, Mt. Kyeryong, Mt. Kaji, Mt. Jiri, Muan, and Mt. Halla). The result of cluster analysis for winter bud characters corresponded well with principal component analysis, as is shown in Fig. 2.

Purpose: Guillain-Barré syndrome (GBS) is a group of clinical syndromes involving acute polyneuropathy secondary to an immune-mediated process. Although affected children generally tend to have a good prognosis, a small subset of children experience residual symptoms that require lengthy and costly rehabilitation. Therefore, we aimed to describe the clinical findings of children with GBS and to investigate factors associated with their outcomes. Methods: A retrospective study was conducted of previously healthy children ≤18 years of age diagnosed with GBS and admitted to Pusan National Children’s Hospital between 2009 and 2018. Results: Of the 38 patients included in the study (23 boys [60.5%]; median age, 4.3 years [interquartile range, 2.8 to 9.7 years]), 28 (73.7%) fully recovered without any residual symptoms, while 10 (26.3%) had residual symptoms more than 6 months after the onset of GBS. The presence of autonomic dysfunction and a ≥50% decrease in compound muscle action potential (CMAP) amplitude from the lower limit of normal were associated with functional deficits at 6 months. Age, sex, type of antecedent illness, cranial nerve involvement, the need for mechanical ventilation, and the subtype of GBS were not significantly associated with functional outcomes. Post-gadolinium enhancement of nerve roots was seen in 71.1% of patients on initial spine magnetic resonance imaging (MRI). Conclusion: Contrast enhancement of nerve roots on MRI was the most helpful initial finding for diagnosing GBS. The presence of autonomic dysfunction and a ≥50% decrease in CMAP from the lower limit of normal were poor prognostic factors for functional outcomes.

Fruit characteristics, saccharinity, and antioxidalive activity of selected clones of Rubes coreanus, grown in Korea, well-known as edible and medical resources, frequently used and which has an excellent pharmacological activity are examined and analyzed. The results obtained from this study can be summarized as follows; Result of surveying characteristics for the fruit and saccharinity variation by collection time, there are some meaningful differences between examined clones and the collection time, exception of the fruit width. From the clones, SG 3 is the biggest in size, the highest in the saccharinity out of five clones, on the other hand, CJ 18 and SH 3 are the opposite. Meanwhile, comparing examined saccharinity factor with maximum temperature and precipitation out of daily climates at Suwon Meteorological Observatory at the same period, on the day the highest temperature is 29.5℃, saccharinity distinctively ascends, but on the day the precipitation is recorded 121.5 mm and next day. the saccharinity descends. Also, five-day saccharinity until the precipitation lower than 0.1 mm per day shows from 10,4 to 11.5 Brix higher than the average saccharinity of 9.7 Brix. Fifteen clones including CA 6 about fruit characteristics in terms of collection layer and saccharinity variation were examined, there is significantly difference among examined clones. but about the collection layer, only saccharinity factor has meaningful significance. For clones, MJ 11 is the biggest and excellent character of 15 clones but the saccharinity, 10.3 Brix lows a bit, MC 9 and HAE 5 are the worst fruit in character but saccharinity is 13.4 Brix and 10.6 Brix which is higher than the average saccharinity of 9.8 Brix. About saccharinity for the collection layer, the fruit average saccharinity, collected from the upper layer which is good at lightness and temperature condition, is 10.2 Brix which shows higher than the one of the fruit, 9.7 Bix and 9.5 Brix collected from the middle or the lower layer. The saccharinity of fruit collected from the middle or the lower layer is lower than the average saccharinity of 9.8 Brix out of 15 surveyed clones. Surveying antioxidative activity resulted from free radical scavenging activity about 30 clones of fruit in total, there is difference between surveyed clones. Especially, Tmmatured fruit extracts exhibited higher free radical scavenging activity of 94.5 to 97.5% which indicates the similarity to Ascorbic acid, unlike other clones, on the concentration of 250 to 1,000 ppm.

As a honey plant, the value of hardy kiwi (Actinidia arguta) has been increased recently for using pollen. The aim of this research was to enhance hard wood cutting propagation efficiencies of hardy kiwi through the pretreatment of growth regulators. We examined the effects of type and concentrations of growth regulators on cutting of hardy kiwi. Three different growth regulators, NAA, IBA and IAA, were prepared by dissolving in distilled water and stem cuttings were kept in solution and they were planted in pearlite medium under greenhouse conditions. After 80 days, the number of rooted stem cutting, the number of root per stem cuttings, root length, root weight, new shoot length and new shoot diameter were determined on stem cuttings. The effects of growth regulators were found significant as statistically. By soaking in 1,000ppm of IBA solution, the survival rate was 82.5% and the rooting rate was 80.0%. For the treatment of IAA 2,000 ppm solution, the survival rate and the rooting rate were 70.0% and 70.0%, respectively. On the other hand, the survival rate and the rooting rate of the control which were untreated of growth regulator were 44.4% and 44.1%, respectively.

Han, Kihwan,Choi, Jae Hoon,Choi, Tae Hyun,Jeon, Sea Yuong,Kim, Jun Sik,Kim, Nam Gyun,Lee, Kyung Suk,Son, Daegu,Kim, Jun Hyung,Kim, Sang-Hyon,Kang, Dawon,Park, Jungbin Lippincott Williams Wilkins, Inc. 2009 Annals of plastic surgery Vol.62 No.3

Currently, endoscopic endonasal reduction and transcaruncular reduction are frequently used as surgical treatments for medial orbital wall fractures. However, these 2 surgical techniques have not been comprehensively compared using objective criteria. Therefore, the results of these 2 techniques were compared retrospectively using 8 objective criteria in patients with medial orbital wall fracture.This study included 48 medial orbital wall fracture patients treated from June 1993 to July 2006: 29 had endoscopic endonasal reduction and 19 had transcaruncular reduction. Computed tomographic scans, double vision field testing for diplopia using Goldmann perimetry, and Hertel exophthalmometer (Richmond Products, Albuquerque, NM) were done pre- and postsurgery.The average follow-up period was 70.8 months. Among patients with pure medial orbital wall fractures, the average reduction rate was 89.2% for the endoscopic endonasal reduction group and 90.7% for the transcaruncular reduction group. One case in the endoscopic endonasal reduction group had a more than 2-mm enophthalmos after surgery. The diplopia correction rate was 1.8% in the endoscopic endonasal reduction group and 2.7% in the transcaruncular reduction group. None of the above differences was statistically significant. However, among patients with pure medial orbital wall fractures compared with the transcaruncular reduction group, the average operation time, the average hospital stay, and the average cost were significantly greater in the endoscopic endonasal reduction group.The 2 surgical methods had a similar effectiveness; however, transcaruncular reduction seemed to be more advantageous with respect to the operation time, the length of hospital stay, and cost.

This study used RAPD markers to assume genetic diversity and variation in selected populations of Hovenia dulcis var. koreana. Ratio of polymorphic RAPD markers were 93.4% in selected populations of Hovenia dulcis Thunb., difference of genetic structure among populations and within populations showed 16.45%, 83.55%, respectively in amount of total genetic variation of 4 populations. Total gene diversity(H^T) that show genetic diversity appeared 0.313 and coefficient of gene differentiation(G^ST) that compare genetic differentiation of populations appeared 0.1645, analysis of AMOVA for variation among populations and within populations was significantly different (P<0.001). Genetic diversity of whole populations showed that 12.44% difference among population and 87.56% difference within populations. As a result, difference within populations was larger than difference among populations in genetic diversity. Nei s genetic distance and cluster analysis appeared that mean genetic distance among populations was 0.076, thus dividing two main groups and geographic relationship did not show in populations.
