Effects of medicinal herbs on the improvement of muscular strength along with the related fatigue factors were evaluated in SD rats. Nine types of treatment groups were fed diets supplemented with 1% herb hot-water extracts (Liriope spicata (LS), Schizandra chinensis (SC), Acanthopanax sessiliflorus (AS), Saliconia herbacea (SH), Eucommia ulmoides (EU), Lycium chinensis (LC), Panax ginseng (red ginseng) (PG), Polygonum multifloum (PM), Glycyrrhizae uralensis (GU)) for 4 weeks. The muscular strength of all groups were measured weekly for 4 weeks. After 4 weeks serum was collected and liver dissected out for the analysis of glycogen and fatigue factors. The liver glycogen contents of all treatment groups ($21.0{\sim}25.9mg/g$) were higher than that of control group (18.1 mg/g). A significantly increase of muscular strength in the fourth week were found in the AS (282.5 gf), SH (277.4 gf), PG (287.2 gf) groups (p<0.05). LS (7.88 mg/dL), SC (7.85 mg/dL), AS (7.64 mg/dL), EU (7.54 mg/dL), LC (7.81 mg/dL) and PG (7.75 mg/dL) groups were significantly reduced in serum inorganic phosphorus concentration measured after 4 weeks (p<0.05). Serum lactate levels of treatment groups ($8.61{\sim}12.18{\mu}g/dL$) were significantly lower than that of control group ($17.45{\mu}g/dL$). These results suggest that medicinal herbs enhanced muscular strength of rats by delaying accumulation of muscular fatigue factor.

This study was carried out to investigate the flora of indigenous habitat of Donghae-si and Samcheok-si in Gangwon-do, Korea. The vascular plants were collected 18 times (from March to October 2011), and were identified as 804 taxa; 127 families, 445 genera, 720 species, 8 subspecies, 69 varieties, 5 forms and 2 hybrids. In the flora of this area, the calcicolous plants were 55 taxa; Cheilanthes argentea, Clematis serratifoliam, Quercus variabilis. Epipactis papillosa, etc. The endangered plants designated and protected by the wildlife protection law, the Ministry of Environment, Korean were counted to one taxon; Cymbidium macrorhizum. The red list of vascular plants according to IUCN valuation basis were examined, endangered species (EN); Prunus yedoensis and Cymbidium macrorhizum, Vulnerable species (VU); Juniperus chinensis, Pulsatilla tongkangensis, Diarthron linifolium and Swertia wilfordii, Near Threatened species (NT); Paeonia japonica, Allium senescens, Epipactis papillosa and Pogonia minor, Least Concern species (LC); Asplenium ruta-muraria, Platycladus orientalis, Monotropa hypopithys and Eleutherococcus divaricatus var. chiisanensis, etc., Data Deficient species (DD); Paeonia lactiflora var. trichocarpa, and Not Evaluate species (NE); Prunus choreiana, Panax ginseng and Polygonatum infundiflorum etc. Korean endemic plants of this area were 26 taxa; Aconitum pseudolaeve, Corydalis hirtipes, Vicia chosenensis, Salvia chanroenica and Hemerocallis hakuunensis, etc. The floristic regional indicator plants found in this area were 130 taxa comprising 11 taxa of grade V, 15 taxa of grade IV, 33 taxa of grade III, 15 taxa of grade II, 56 taxa of grade I. The naturalized plants were identified as 67 taxa and the percent of naturalized index (NI) was 8.3% of total 804 taxa vascular plants.

To provide fundamental information to areas that lack data on the plant resources and the ecosystem, this study conducted a survey on the vascular plants in Mt. Jigisan in Hongseonggun. The vascular plants identified during the six-round field surveys were a total of 443 taxa: 96 families, 286 genera, 391 species, 7 subspecies, 40 varieties, 3 forms, and 2 hybrids. On floristic regional of Korea, Mt. Jigisan is deciduous broad-leaved and conifer-mixed forest which is south province of Korean peninsula. 4 taxa of Korean endemic plants such as Populus ${\times}$ tomentiglandulosa, Forsytsythia koreana, Forsytsythia ovate, and Iris rossii var. latifolia were collected. The vascular plants on the red list according to IUCN evaluation basis were found to be 6 taxa: Vulnerable (VU) species of Forsytsythia ovata, Least Conern (LC) species of Chionanthus retusus, Pseudoraphis ukishiba, and Cymbidium goeringii, and Not Evaluate (NE) species of Panax ginseng, and Fimbristylis verrucifera. The floristic regional indicator plants were found 27 taxa: 2 taxa of grade V, 3 taxa of grade IV, 6 taxa of grade III, 4 taxa of grade II, and 12 taxa of grade I. The specific distribution plants were found 27 taxa: 4 taxa of northern part of plants, 12 taxa of southern part of plants, 10 taxa of isolation distribution of plants, and 1 taxon of recently reported Viola betonicifolia var. albescens. The invasive alien plants were identified as 67 taxa. The naturalized index (NI) was 15.12%, and urbanization index (UI) was 20.9%, respectively.

The ultrastructural changes of embryo and endosperm cells were observed during the green fruit with embryo about $250{\mu}$ long to germination. 1. In the embryo cells of green fruit with embryo about $250{\mu}$ long, mitochondrial cristae and plastid are undifferentiated and dictyosome are occasionally observed. There are electron-opaque globoids in the vacuole and a lot of spherosomes in the outer layer of smooth endoplasmic reticulum. Endosperm is filled with spherosomes and electron-opaque protein bodies surrounded by spherosomes, and due to these, other organelle are not observed. 2. In the embryo cells of seeds with red seed coat, mitochondrial cristae are well developed, electron-opaque globoids increased, and vacuoles are enlarged. In the endosperm, however, spherosomes increased, protein bodies are enlarged, and electron-opaque globoidal crystals are dispersed within them. 3. In the procambium and epicotyl cells of dehiscent seed, Golgi vacuoles and vesicles are well developed, and mitochondrial cristae are also well differentiated. Spherosomes are numerously present and radicle cells, peripheral cells of hypocotyl, and vacuoles of cotyledon are well differentiated. Endosperm is filled with spherosomes containing electron-opaque granules and protein bodies are surrounded by a single membrane. There are acid phosphatase around globoids and spherosomes. 4. At the time of seeding, spherosomes markedly increased in the outer layer of cotyledon and protein bodies are also observed. Cell organelles are differentiated and plastids containing starch are also present. 5. In the outer $2{\sim}3$ layers of cotyledons, radicle cells, and peripheral cells of hypocotyl during post-seeding to germination, spherosomes and plastids with starch increased, and mitochondria and microbodies are also found around the nucleus of embryo cells. With approaching, the germination stage, in the endosperm contacting with embryo, vacuoles are well differentiated but spherosomes decreased. There increased electron-opaque materials within vacuoles. In other endosperm, with the decrease of spherosome, mitochondria increased and electro n-opaque globular bodies are formed and gradually increased. The outer layer of protein bodies are reduced while electron-transparent portions are enlarged and fused together to occupy the outer layer where small particles are formed. 6. In the endosperm of germination stage, spherosomes decreased while protein bodies, are fused together to form 2 or 3 within a cell.
