Total cholesterol level in mice with hypercholesterolemia was determined after intraperitoneal administration of the methanolic extract of some medicinal plants. From the data obtained, it was suggested that the methanolic extract of Elaeagnus crispa, Ixeris dentata, Prunus davidiana, Eriobotrya japonice, Aralia elata and Phragmites communis produced a significant hypocholesterotemic effect. In the case of the extract of Saussurea diamantiaca, on the other band, the total cholesterol level was markedly increased. The methanolic extract of Ixeris dentata, Prunus davidiana and Phragmites communes also decreased the level of blood glucose in alloxan-diabetic male albino mice while that of Eriobotrya japonica, Allium tuberosum, Houttuynia cordata and Eucommia japonica did not produce this effect.

Two individuals of intergeneric hybrids in the crossing of Brassica pekinensis ♀$\times$Raphanus sativus ♂ were obtained, and among the three kinds of plants, Brassica, Raphanus, and F1, comparison on the mega- and microsporogenesis, megagammetophyte formation, and morphological changes in the developing sporangia, etc., were made. Differences between Brassica and Raphanus were observed in the shape of mega- and microsporangia, their changes in development, and the formation of megagametophyte. Sporangia of the F1 plants, until pre-meiotic stage, show intermediate, maternal, paternal, or vigorous inclination, and the difference of these characteristics when compared with those of the parent is slight. Meiotic irregularity resulted from the intergeneric hybridity of F1 plant gives rise to the abnormal mega- and microspore and accompanied abortive female and male gametophytes, bringing about the remarkable differences from its parent in the morphological changes of the developing mega- and microsporangia.

Morphological and anatomical characters of Amphiroa misakiensis Yendo are investigated with field materials and taxonomic accounts are given to the species. The plants grow on rocks, mussels or non-articulated corallines from the subtidal zone of Cheju island, and is characterized by recumbent and spreading habit from the substrate. The species is well defined by about 4 cm height, loosely tufted thallus with irregularly dichotomous branches, flat and irregularly broad intergeniculum in upper part, geniculum developing by cracking and sloughing of calcified cortical tissue overlying uncalcified genicular tissue, five to thirteen-tiered geniculum with unequal length, and conceptacles buried in cortices of intergeniculum. Reproductive structures in tetrasporangial, male and female plants are typical of Amphiroa. The structure and developmental patterns of conceptacles are very similar to those shown in previous studies.

The hypoglycemic effects of four edible plants (Angelicae tenuissimae (A. ten.), Pleurospermum kamtschaticum (P. kam.), Adenophora remotiflora (A. rem.) and Zanthoxylum schinifolium (Z. sch.)) in streptozotocin (STZ) -induced diabetic rats were investigated. Sprague-Dawley male rats weighing 190-230 g were induced diabetes mellitus by the STZ injection (45 mg/kg) into the tail vein and were divided into six groups ; normal, STZ-control and four edible plant groups (A. ten., P kam., A. rem. and Z. sch. groups). Normal and STZ-control groups were fed a AIN-93 diet and four groups of STZ-induced diabetic rats were fed one of each experimental diets containing 10％ of the edible plant powder for 4 weeks. Diabetic rats showed the lower weight gain compared to the normal rats. In experimental groups except P. kam., AST activities were close to normal. A. ten. group were lowered ALT activities slightly. The plasma glucose levels of the diabetic experimental groups were significantly decreased at 4th week. The plasma insulin levels in diabetic experimental groups were not significantly different compared to the STZ-control group. The liver glycogen levels in STZ injected rats were significantly lower in compared to the normal rats. However no significant differences were found in response experimental plants intake in diabetic rats. The muscle glycogen were not significantly different among all the groups.

본 연구에서는 천연소재 혼합물이 혈중 지질 함량 및 부고환 지방세포의 크기에 미치는 영향을 측정하였다. 그 결과 혈액 중 총 콜레스테롤과 LDL 콜레스테롤은 천연소재 섭취에 의한 유의적인 감소 효과가 나타나지 않았지만, 중성지방은 정상식이군에서 감소하였고 HDL 콜레스테롤은 정 상식이군에서 증가하였다. 부고환 지방조직은 고지방식이 섭취에 의해 지방세포 크기가 유의적으로 증가되었으나 천연소재 섭취로 인하여 유의적으로 감소하였다. 이는 천연소재섭취에 의해 체지방 축적이 억제되어 지방세포의 hypertrophy를 억제했기 때문으로 사료된다.

The fruit color characteristics and persisting period of deciduous woody landscape plants were investigated through the field survey in Suwon region from January 1, 1992 to March 20, 1993. The summary of the study results was as follows; The total fruit color persisting period was about 320 days from May 1, 1992 when Prunus mume was beginning of fruit coloring, to March 20, 1993 when the fruits of Platanus occidentalis and platanus X acerifolia were persisting. And the plants of fruit persisting period over 60 days after leaf falling were Vibumum erosum, Ilex serrata, Ilex verticillata 'Christmas Cheer', Platanus X acerifolia, Platanus occidentalis, Berberis thunbergii 'Atropupurea', Ligustrum obtusifolium. According to the KBS standard color number, 52.6% of of the fruit color were red, 18.9% yellow, 11.6% black, green 9.5%, white 2.1%, violet 1.1%, and red is followed black 4.2%. Evodia daniellii, Ilex verticillata 'Christmas Cheer', Ilex serrata, Ginkgo biloba, Lindera obtusiloba, and Lindera erythrocarpa should be planted male and female species together for fruits. We got the new information on the fruit color characteritics and persisting period of Malus 'Hopa', Malus 'Almey', Malus 'Pioneer X', Acer rubrum, Malus prunifolia, Pyrus serotina, Berberis thunbergii 'Atropurpurea', Vibumum rhytidophyllum, Rosa spp. Vitis vinifera, Vaccinium angustifolium, Ilex verticillata 'Christmas Cheer', Magnolia stellata, Aronia arbutifolia, Sorbus alnifolia, Lonicera japonica var. aueroreticulta, and Ligustrum X vicaryi. And we need to introduce new cultivars of woody landscape plants including Malus spp, Berberis spp, Sorbus alnifolia yellow autumn leaf clone etc. for the better planting design. The fruit persisting period of woody landscape plants studied by fruit name was that sorosis 276 days, samara 155 days, legume 153 days, hip 133 days, pome was 124 days, drupe 92 days, berry 73 days, capsule 67 days, follicle 55 days and nut 52 days respectively.

Curcuma longa L. (C.L), Curcuma aromatica Salisb. (C.A) and Zingiber officinale Rosc. (Z.O) of Zingiberaceae plants which are well known as effects of natural anti-oxidant, anti-cancer and anti-inflammatory. We examined that the Zingiberaceae plants are involved in development and modulation of orofacial pain in rats. Male, 7- to 8-week-old, Sprague-Dawley rats weighing 240~280 g were used in this study. Experiments were performed using acute pain model that was caused by the injection of 5% formalin into the right vibrissa pad. The number of scratching or rubbing to the injection site was recorded for 9 consecutive 5-minute intervals following injection of formalin. The experimental groups were acute orofacial inflammatory pain; control group (formalin, 5%), vehicle group (5% formalin after sodium carboxymethyl cellulose), single administration group, single mixed administration group, repeated administration group. The experiments were performed various concentrations of Zingiberaceae plants extract. Therefore, oral administration of C.L, C.A, and Z.O (p.o., concentrations of 12.5, 25 mg/mL) in orofacial inflammatory pain model substantially decrease the nociceptive behavior in a concentration dependent manner. And it tended to decrease at low concentration (12.5 mg/mL) of single mixed and repeated administration more than single administration. This result means that Zingiberaceae plants extract affects the modulation of acute orofacial inflammatory pain. Thus, Zingiberaceae plants extract may be a potential therapeutic treatment for orofacial inflammatory pain.
