An experiment was performed using 20 calves of about one-month old to investigate the effect of chelation therapy with calcium disodium ethylenediaminetetraacetate ($CaNa_2$EDTA) alone or along with antioxidant $\alpha$-tocopherol in lead loaded calves on blood trace minerals, erythrocytic sulfahydryl groups and some haematobiochemical parameters. Fifteen calves were given lead orally at a daily dose of 7.5 mg of 99% pure lead acetate/kg body weight for 28 days. Then the lead was withdrawn on day 28 and the calves were randomly divided into three groups. Each group of five animals was either treated with $CaNa_2$EDTA alone at the dose rate of 110 mg/kg body weight in two divided doses for 4 days or along with $\alpha$-tocopherol at the dose rate of 100 mg/kg body weight orally daily for 7 days, keeping the remaining five calves as lead-exposed untreated controls. Blood samples were collected at the end of the lead exposure (day 0) and thereafter on day 2, 4, 7 and 10 from the start of the chelation treatment. The treatment with EDTA alone led to slow but non-significant improvement in blood copper level, but incorporation of antioxidant $\alpha$-tocopherol in chelation therapy resulted in its significant decline, as recorded on day 7-post treatment. Withdrawal of lead or treatment with $CaNa_2$EDTA alone or along with $\alpha$-tocopherol enhanced the erythrocytic thiol contents and the levels of T-SH and P-SH became statistically (p<0.05) comparable to those of lead-exposed controls by day 7 and 4, respectively. There was no significant (p>0.05) change in serum urea, creatinine, total protein and albumin levels between the treatment groups. It is concluded from the present investigation that treatment with $CaNa_2$EDTA at the present dose rate is safe to be used for chelation in lead loaded calves.

Objective: To evaluate the efficacy and safety of dienogest treatment in patients who had received dienogest for 12 months or more to treat endometriosis. Methods: We analyzed the clinical data of 188 women with endometriosis who had been treated with 2 mg of dienogest once a day for 12 months or more at a single institute. We evaluated changes in endometriosis-associated pain and endometrioma size, recurrence rate, and adverse events following dienogest administration. Bone mineral density (BMD) was measured in patients who were prescribed dienogest for more than 18 months. Results: Pain was significantly reduced at 12 months after dienogest medication. In those treated with dienogest due to recurrent endometrioma, the size of the endometrioma was significantly decreased at the 12-month and 18-month follow-ups. We found only one case of sonographic recurrence during dienogest administration among those who were treated postoperatively to prevent recurrence (1 of 114, 0.9%). The most common adverse drug reaction was uterine bleeding (3.2%), and other adverse events were generally tolerable and associated with low discontinuation rates (5.2%). Among the 50 patients in whom BMD was measured, 10 patients (20%) had a Z-score below the expected range for age. Conclusion: The administration of dienogest for a year or more seems to be highly effective in preventing recurrence after surgery, reducing endometriosis-associated pain, and decreasing the size of recurrent endometrioma, with a favorable safety and tolerability profile. However, BMD should be checked in patients on long-term medication due to possible bone loss in some women.

떫은 감 분말의 첨가량 (0, 5, 10, 15, 20%)을 달리하여 설기떡의 품질 특성을 조사하였다. 감설기의 수분함량은 감 분말 첨가군 무 처리구에 비해 낮게 나타났으며, 환원당, 유리당(fructose, glucose, sucrose), 무기질(Ca, K, Mg) 함량은 떫은 감 분말 함량이 증가할수록, 함량이 증가하는 경향을 보였다. 색도는 떫은 감분말의 첨가량이 증가할수록 L값은 낮아지고, a값과 b값이 증가하였고, texture 측정에서 adhesiveness, cohesiveness, gumminess, chewiness 값은 낮아지는 경향을 나타내었다. 관능검사 결과 떫은 감분말의 첨가가 무 처리구에 비해 전반적인 기호도가 높은 간을 나타났고, 15% 첨가구가 가장 높은 값을 나타내었다. 이상의 결과로 설기떡 제조시 첨가하는 설탕시럽 대용으로 여러가지 기능성물질과 단맛을 함유하고 있는 떫은 감을 식품의 소재로 이용될 수 있는 충분한 가치가 있다고 사료된다.

This study was conducted to obtain basic data which can be applied to process of canned boiled Kwamaegi. Commercial Kwamaegi was cut into $2{\times}3$ cm lengths, filled 90 g into can (301-3) and added with 60 g water and then precooked for 10 min. at $100^{\circ}C$. And water layer was drained. The precooked Kwamaegi was packed into the can, and added with 60 g of mixed salt solution, which is mixed with salt 0.5% and bamboo salt 0.7%. The cans were seamed using a vacuum seamer, and then sterilized for various Fo values (Fo 8~12 min.) in a steam system retort at $121^{\circ}C$. pH, VBN, amino-N, total amino acid, free amino acid, color value (L, a, b), texture profile, TBA value, mineral, sensory evaluation and viable bacterial count of the canned boiled Kwamaegi produced with various sterilization condition(Fo 8~12 min.) were measured. There was no remarkable difference between sterilization conditions and sensual characteristics. The results showed that the product sterilized at Fo 8 min. was the most desirable because this condition is the most economical and tasty.

Recently mycorrhizal research has been one of the most fast-growing research areas in modern plant science and microbiology. The application potential of mycorrhizal techniques to agriculture and forestry is enormous in view of the ubiquitous nature of mycorrhizae and known benefits of mycorrhizae to host plants. Unfortunately, very few scientists in Korea are currently involved in mycorrhizal research. When a team of American plant pathologists visited Korea in September 1982 to participate in the Korea-U.S.A. Joint Seminar on Forest Diseases and Insect Pests, they were surprised by the principal author's statement that there was no single research project on mycorrhizae sponsored by Korean government or any scientific institutions. The author initiated a few years ago a research project on the ecology of tree mycorrhizae with a foreign financial support. Major areas of interest were survey of ectomycorrhizae in relation to soil fertility, taxonomic distribution of mycorrhizae among woody plants, identification of ectomycorrhizal fungi, and growth response of woody plants to artificial inoculation. In spite of the enormous application potential of mycorrhizae to agronomic plants, the subject of mycorrhizae has not been recognized by Korean agronomists, foresters or pathologists. The purpose of this review rather written in Korean is to introduce the techniques of mycorrhizal research to Korean scientists and to urge them to participate in challenging new scientific field which might bring us a remarkable increase in crop productivity and tree growth through manipulation of this unique symbiosis. In this review, following topics were discussed in the same order: introduction; brief history of mycorrhizal research; morphology and classification of mycorrhizae; distribution of mycorrhizae in plant kingdom and in soil profile; physiology of mycorrhizae (functions, mineral nutrition, mycorrhizal formation); interaction of mycorrhizae with soil-born plant pathogens. mycorrhizae in nitrogen-fixing plants; application of mycorrhizal techniques to nursery practices (isolation, culture, inoculation, and response); prospect in the future.

토양으로부터 탈지대두박을 잘 분해하는 단백질 가수분해효소를 생산하는 미생물을 분리하여 형태적, 생화학적 특성과 세포벽 지방산조성을 조사한 결과, 분리된 세균은 Aeromonas hydrophila로 동정되었다. 분리된 세균은 glycerol을 탄소원으로, tryptone 및 $(NH_4)_2HPO_4$을 진소원으로, $CaCl_2$를 무기원으로 사용한 배지에서 효소를 가장 많이 생산하였으며, 생산된 효소의 반응최적 pH는 8.0이고, 반응최적온도는 $65^{\circ}C$였다. 이 효소는 $55^{\circ}C$ 이하의 온도에서, pH 7.0에서 13.0의 범위에서 비교적 안정한 것으로 나타났다. 또한 이 효소는 금속이온 $Cu^{2+},\;Hg^{2+}.\;Mn^{2+}$ 및 $Zn^{2+}$에 의해서 효소활성이 저해를 받고, 효소저해제 phenylmethylsulfonyl fluoride (PMSF)와 ethylenediaminetetraacetic acid (EDTA)에 의해서 효소활성이 강력히 저해되는 성질로부터 효소활성부위에 serine기와 금속이온을 갖고 있는 것으로 밝혀졌다.

This study was investigated to obtain basic data which can be applied to processing of retort pouched seasoned sea mussel. Shell was washed and steamed before shucking. Sea mussel meat was seasoned in boiled and mixed seasoning sauce(soy sauce 23%, monosodiun glutamate 2%, sorbitol 2%, sesame oil 1%, vinegar 2%, starch syrup 15%, water 55%) for 30 min. The seasoned sea mussel was vacuum packed in plastic film bag and sterilized for various Fo values(Fo 7~13 min.) in a hot water circulation system retort at $121^{\circ}C$. The chemical composition such as pH, VBN, amino-N, total amino acid, free amino acid, color value (L, a, b), texture profile, TBA value, mineral, sensory evaluation and viable cells count of the retort pouched seasoned sea mussels sterilized with various conditions(Fo 7~13 min.) were measured. The same experimental items were also measured during storage. There was no remarkable difference between sterilization conditions and sensual characteristics. The results showed that the product sterilized at Fo 7 min. was the most desirable because this condition is most economical.
