The objective of this study was to evaluate the sperm liquid storage diluted with Brine Mineral Water (BMW) in miniature pig. Therefore we performed to find optimal concentration of BMW. The ejaculated semen from miniature pig was collected by gloved-hand method. The collected semen was diluted with dilution solution (Mulberry Ⅲ; modified-Modena B) which BMW was added. Concentration of BMW was 0, 2.5, 5, 7.5, 10 and 12.5% in dilution solution. The diluted semen was preserved at 17℃. Sperm ability was estimated by viability, capacitation acrosome reaction using chlortetracycline (CTC), hypoosmotic swelling test (HOST), morphologic abnormality. The diluted semen was observed for 7 days. The viability was significantly measured higher at 2.5% concentration of BMW than other groups (p<0.05). The AR-pattern of CTC analysis was significantly measured lower at 12.5% concentration of BMW than other groups (p<0.05). However, abnormality was not significantly different among all the groups (p<0.05). In conclusion, viability of sperm was the highest at 2.5% concentration of BMW but BMW had a negative effect on HOST, capacitation and acrosome reaction in sperm of miniature pig.

Arthrobacter sp. L-3이 생성하는 glucose isomerase를 DEAE-cellulose column chromatography법으로 2단계 NaCl농도 구배로 용출함으로서 순수분리하였다. 이것이 SDS-acrylamide gel electrophoresis상에서 단일띠를 보임으로서 매우 잘 분리되었음을 알 수 있었다. Glucose isomerase의 K_m값과 V_max값이 각각 0.175M, 0.29(㎎/㎖/min)로 얻어졌다. 한편, SDS-acrylamide gel electrophoresis와 Sephadex-G100-50에 의한 gel filtration으로부터 분자량이 각각 42, 000과 180, 000으로 얻어져, 이 효소는 분자량이 42, 500인 4개의 subunit로 구성되었음을 알 수 있었다.

The morphological changes of fresh beef treated with ficin(0.1% : 2 hrs, 6 hrs)were examined with transmission electron microscope(TEM), the results obtained were as follows ; Connective tissue protein in fresh beef treated with ficin became gradually fragmentation and was occured stabilization with time. The length of sarcomere in myofibrillar protein was elongated, M-line became dim, and the I-band of Z-line was broken and became fragmentation with time.

Background : The major compounds of Angelica species are decursin, decursinol angelate, nodakenin, umbelliferone and β-sitosterol, which act anti-inflammatories, reduce pains, protect the liver and enhance the immune system. This study investigated the chemical compositions, minerals, metals, sugars and overall amino acid composition in Angelica gigas Nakai. Methods and Results : Powder of Angelica roots smaller than 30 mesh were used. Physico chemical analysis revealed the presence of carbohydrates (62.0%), crude proteins (13.9%), moisture (11.4%), crude fats (7.3%) and ash (5.4%). Results showed that potassium was present in the highest amount (1,859 ppm), followed by magnesium (214.5 ppm), calcium (147.3 ppm) and sodium (6.0 ppm). Free sugar profiles showed the presence of sucrose (29.3 g/100 g). The total amino acids concentrations was 9,752 ㎎/ 100 g, the most common and dominant amino acids were arginine (2,181 ㎎/100 g), glutamic acid (1,212 ㎎/100 g) and aspartic acid (834 ㎎/100 g). The total free amino acids contents was 1,476 ㎎/100 g, in which the most common amino acid were arginine (932 ㎎/100 g), glutamic acid (127 ㎎/100 g), and γ-aminobutyric acid (80.4 ㎎/100 g). The fatty acid composition of A. gigas showed a higher concentration of unsaturated fatty acids such as linoleic acid (443.9 ㎎/100 g) and palmitic acid (181.3 ㎎/100 g) according to gas chromatography. Conclusions : These results showed that Angelica roots can be used in various fields of foods and medicines, and in the preparation of cosmetics.
