Biotae Orientalis has been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Oriental Medicine. This experiment examined the effect of an extracts, obtained from the acetone and MeOH extracts of dried or fresh Biotae Orientalis, on hair growing activity of the C57BL/6N mice after topical application to skin. First, We examined on hair growth activity of extracts of Biotae Orientalis compare to control and 1% minoxidil groups. Second, We investigated on the number of hair follicle and mast cells after topical application of extracts of the Biotae Orientalis to skin for 16 day. Third, We investigated immunoreactive density of vascular endothelial growth factor(VEGF), protein kinase C-${\alpha}$(PKC-${\alpha}$) and stem(mast) cell factor(SCF) in skin of C57BL/6N mice by immunohistochemical methods. I fourth investigated changes of subpopulation of splenocytes and thymocytes in C57BL/6N mice for 16day using laser flow cytometry. The results were as follows : Hair growing effect of acetone and MeOH extracts of dried and fresh Biotae Orientalis was observed in 70%, 90% and 60% in hair removed skin area in 16 day respectively. Immunoreactive density of VEGF and PKC-${\alpha}$ in skin of experimental groups was weakly stained compare to control group in 10 day. Immunoreactive density of stem cell factor in skin of experimental group was heavily stained compare to control group in 10 day. Splenic TH/TC Iymphocytes of lived MeOH extracts group significantly increased compare to control group. TH cells in thymic T lymphocytes were increased compare to control group. These experiment suggest that acetone and MeOH extracts of Biotae Orientalis may be used for topical treatment of alopecia areata.

The purpose of the present study was to examine the seminiferous epithelium cycle of Bombina orientalis using a light microscope. The cycle was divided into a total of 10 stages, according to the morphological characteristics of the cells. The spermatogenetic cells included primary spermatogonia, secondary spermatogonia, primary spermatocytes, secondary spermatocytes, spermatid and sperm. At stage I, the primary spermatogonia was located closer to basal lamina of the seminiferous tubule without spermatocyst formations. Especially at the stage II, the secondary spermatogonia were located in the spermatocyst. The primary and secondary spermatocytes were found from stages III to VI. The secondary spermatocytes were smaller in size than the primary spermatocytes, but they had thicker nucleoplasm and smaller nuclei. The round-shaped, early sperm cells were formed in stage VII, and further divided at stage VIII to have more concentrated nucleoplasm before division to matured sperm cells. At stage X, the matured sperm cells emerged from the spermatocyst. Considering the above results, this study presented the special characteristics in the generation and type of sperm formation. The germ cell formation occurred in various stages, like the perspectives of Franca et al (1999), ultimately, providing taxonomically useful information.

Declines in amphibian populations are occurring worldwide, and have been attributed to many factors, including anthropogenic environmental changes. One of the ramifications of such declines is abnormalities in many amphibian species. A strong association has been detected between human activities and abnormalities in amphibian populations, but studies on this association are largely focused on lentic species. In this study, it was analyzed whether the degree of local human activity was associated with the rate of abnormalities in Bombina orientalis which inhabited lotic environments. We found that the proportions of abnormalities in wild populations of B. orientalis increased, when i) the closest human land use was located within 100 m from the frogs' habitat, and ii) the proportion of human land use within a 300-m radius was high. Our findings suggest that human activity has a negative impact on the fitness of nearby amphibian populations, and that wild populations very close to human-induced disturbance are affected.

The compositional changes of wormwood (Artemisia princeps var. orientalis) essential oils were studied under 4 different storage conditions i.e., being exposed to air at 20 and $40^{\circ}C$. Sixty-four volatile compounds consisting of 24 terpene hydrocarbons, 18 alcohols, 11 ketones, 6 esters, 1 aldehyde, 2 hydrocarbons, and 2 oxides were identified on the basis of their mass spectra characteristics and retention indices in original wormwood essential oils. Identified compounds constituted 80.53% of the total peak area. Borneol (12.13%) was the most abundant compound, followed by $\alpha$-thujone (8.66%), T-cadinol (6.67%), and 1,8-cineole (6.21%) in original wormwood essential oils. Under the condition of $40^{\circ}C$ of temperature with the cap being opened for 3 min everyday respectively during 6 months of storage, the total amount of functional groups in essential oil determined by peak area percent were decreased by 79.45%, at most. The total level of monoterpene hydrocarbons decreased markedly in the aerobic condition and high temperatures. Whereas the total level of esters increased significantly. Wormwood essential oils were stored in experimental conditions, with the changes in the volatile compounds of essential oils being accelerated by high temperatures and contact with the atmosphere.

Nalita wood (Trema orientalis), one of the fastest growing woods in the world, is characterized anatomical, morphological and chemical properties at annual growth ring level in order to investigate as papermaking raw material. The proportion of fibers and vessel was increased with an increase of growth ring (from pith to bark). The fiber length of Nalita was increased with increasing growth ring, and an average fiber length was about 817 um. The average basic density of Nalita was about 0.38 g/cc. The total lignin & holocellulose in Nalita were increased and ash & alcohol-benzene extract decreased from pith to bark. These values were about 23.5 - 24.4 ％, 78.1 - 80.1 ％, 1.04 - 0.92 ％ and 2.1 - 1.8 ％, respectively. The xylan was the predominant sugar in the hemicellulose of Nalita.

양서류 오종 Bombina orientalis , Cacopoides borealis , Bufo bufo asiaticus, Rana nigromaculata nigromaculata, Rana rugosa 의 혈청단백질을 Paper electrophoresis 의 방법으로 분석비교하였다. 그 결과 Bombina orientalis 의 혈청단백질은 인간의 것과 마찬가지로 5개의 protein fraction으로 나누어지고 그중 fraction III 단백지링 가장 많은 함량을 구성하며 peak 가 가장 높다. Cacopoides borealis 와 Bufo bufo asiaticus 의 혈청단백질은 4개의 protein fraction 으로 나누어지는데 Cacopoides boreealis 에서는 fraction IV protein이 Bufo bufo asiaticus 에서는 fraction I protein 이 가장 많은 함량을 구성하고 있다. Rana nigromaculata nigromacuata 와 Rana rugosa 는 graph 상에 나타난 peak로 보면 상호유사하나 protein fraction 수는 차이가 있다. 그리고 albumin은 전 함량 per centage의 약 반을 차지하고 있다. 즉 종간의 거리가 멀수록 protein fraction 의 차이가 percentage 함량에 있어서 명백하여짐을 암시하여준다.
