Objectives : The aim was to study experimentally the effects of YUKWOOLTANG(li${\`{u}}$y${\`{u}}$-t${\={a}}$ng; YWT) induced by sodium levothyroxine. Methods : Spargue-Dawley rats were separated into four groups. Except normal group, the other three groups were treated with sodium levothyroxine $32{\mu}g$/200g for 5 days. Among the three groups, two except one(as control group) were treated YWT extract separately(sample A:75mg/200 g, sample B: 150mg/200 g ). T3-uptake, T3, T4, r-TSH, total cholesterol, total protein change in the serum of rats were measured after medication of solid extract of YWT. Results : As a result of this study, in the serum T3-uptake content, sample A showed significant decrease in comparison with control group, but sample B group did not show significant decrease. 2. In the serum T3 content, sample B showed significant decrease in comparison with control group. In the serum T4 content, YWT showed significant decrease in comparison with control group. The serum r-TSH was shown with valuable increase in sample B of YWT. The serum total cholesterol was not shown with valuable increase in YWT. The serum total protein was shown with valuable increase in YWT. Conclusion : These results suggest that YWT is effective to cure Hyperthyroidism.

The age and growth of the blackthroat seaperch Doederleinia berycoides was investigated based on samples captured in the southern seas of Korea from January to December, 2006. Age was estimated by analyzing otolith growth rings. The spawning period was extrapolated from August to November based on monthly changes in the gonad somatic index. The relationship between total length and otolith radius was analyzed separately for each sex with TL=-15.6174+10.3274R for females and TL=-4.4083+7.0749R for males. From the parameters calculated using average total length and weight when the year ring was formed, the growth of D. berycoides was expressed by von Bertalanffy growth equations as $L_t=34.71(1-e^{-0.2557(t+0.2078)})$, $W_t=713.85(1-e^{-0.2557(t+0.2078)})^{3.1972}$ for females, $L_t=27.37(1-e^{-0.3388(t+0.7362)})$, $W_t=353.91(1-e^{-0.3388(t+0.7362)})^{3.1647}$ for males, and $L_t=34.20(1-e^{-0.2530(t+0.2871)})$, $W_t=674.10(1-e^{-0.2530(t+0.2871)})^{3.1171}$ for pooled sexes, where L is total length at age t.

To clarify the safety of both total and near-total thyroidectomy, and to guide a selectionof an adequate type of surgical treatment of thyroid diseases, 192 consecutive total or near-total thyroidectomy cases were reviewed. They were divided into two groups: ont, the total thyroidectomy group(Group T,N=111) and the other, the near-total thyroidectomy group (Group NT, N=81). In both groups, complication rates, associations of complication rates with extents of surgery and stage of lesion were observed. Complication rate was significantly higher in Group T (53.6% vs 12.3%, p<0.05). But the rate of permanent complications such as permanent hypoparathyroidism and recurrent laryngeal nerve injury was remarkably low(4.5% in Group T, 6.0% in Group NT) and shows no significant difference in both groups. There was no permanent complication in cases where any type of neck dissection had not been performed regardless of the type thyroidectomy. But among whom underwent central compartmental neck dissection(CCND) and functional neck dissection(FND), 4(4.4%) and 4(6.4%) cases showed permanent complications. There was no statistical significance in differences between Group I and NT. In cases who underwent concomittant classical radical neck dissection(RND), 3(25.5%) showed permament complications. In this subgroups, complications were significantly higher in Group T(p<0.005). Complications were also directly related to the stage of the lesion. Only one patient showed permanent complication in 74 intracapsular lesions but 9 permanent complications were observed in 118 advanced lesions. We could clarify both total and near-total thyroidectomy were safe operations and the complications were related to accompanying neck dissections and the disease status rather than total or near-total thyroidectomy itself. Thus, we think that for the cases where higher complication rates are expected, such as locally advanced thryoid cancers or the cases which required wider neck dissection, the near-total thyroidectomy would be a preferrable method.

Seasonal and spatial variations in propagule numbers of Trichoderma species were investigated every other month for one year in deciduous and coniferous forest soils and evaluated the relationships of Trichoderma spp. populations to soil environmental factors. The total population of Trichoderma spp. increased until summer and then declined until winter. The yearly mean frequency of Trichoderma spp. exceeded 1.4% of total fungal propagules in two sites. Decreases of absolute an relative propagule numbers of Trichoderma spp. with increasing soil depth were found and variation in Trichoderma spp. propagules caused by differences in soil depth ($0{\sim}50cm$) was greater than that caused by differences in sampling time. The most common species occurring in two sites was T. viride, followed by T. polysporum, T. koningii, and T. hamatum. Individual species of Trichoderma showed diferent abundance trend in accordance with sampling time. T. viride was dorminant from spring to autumn, while T. polysporum dominated over the other speicies in winter. Variations in propagule number of Trichoderma sppp. were principally mediated by the actions of biotic environmental factors rather than by the direct effects of abiotic factors. In multiple-regression analyses, 48% of the total vaiation in Trichoderma spp. propagules in deciduous site could be accounted for by total fungal propagules and soil CMCase actvity. In coniferous site, 65% of total variation could be accounted for by total fungal and bacterial propagules, moisture content and organic carbon content.

유화형 소시지에 마늘즙과 양파즙을 각각 1%와 3%를 첨가하여 냉장온도($4{\pm}1^{\circ}C$)에서 21일간 저장하면서 pH, peroxide value, TBARS, 총 미생물수 및 아질산염 잔존량을 조사하였다. 실험구는 마늘즙과 양파즙을 첨가하지 않은 대조구, 마늘즙 1% 첨가구는 T1, 마늘즙 3% 첨가구는 T2, 양파즙 1% 첨가구는 T3 및 양파즙 3% 첨가구를 T4 등 5개 처리구로 나누어 0, 7, 14 및 21일간 저장하면서 실험하였다. pH는 저장기간이 경과하면서 모든 처리구에서 서서히 감소하였고, 마늘즙 첨가구는 양파즙 첨가구보다 낮았으며, 대조구의 pH가 가장 높았다. 과산화물가는 저장기간 동안 증가하였고, 마늘즙과 양파즙의 첨가구는 대조구보다 유의적으로 낮은 함량을 보였다(p<0.05). TBARS는 저장기간 동안 직선적으로 증가하였으며, 마늘과 양파를 첨가한 유화형소시지는 대조구보다 낮아 마늘과 양파즙이 지방산화를 지연시켰고, 마늘이 양파보다 효과적이었다. 그리고 마늘즙과 양파즙의 첨가량이 많을수록 TBARS값은 낮은 경향이었다(p<005). 총 미생물수는 저장기간이 지나면서 모든 첨가구에서 증가하였고, 저장 0일에는 처리구간 유의성이 없었으며, 처리구간에는 마늘즙 3% 첨가구인 T2에서 유의적으로 낮은 미생물수를 나타내었다. 아질산염 잔존량은 저장기간이 경과하면서 감소하였는데 T2에서 다른 시험구보다 많이 감소하였다. 이상의 결과를 종합적으로 고찰해보면 마늘즙 3% 첨가구는 산화 및 미생물 성장 억제 가능성이 있는 것으로 사료된다.

In order to investigate experimental effects of Yangkyuksanwha-Tang, which is the typical prescription for diseased SOYANGIN, on diabetes rats, the observation and measurement was made on the content of volume of blood glucose, total cholesterol, triglyceride, phospholipid, total protein, electrolyte($K^+$, $Na^+$) in serum, by dosing the cooked Y.S.T. to diabetic rats, induced by streptozotocin and following result was obtained. 1. The volume of blood glucose, in the diabetes rats, was decreased significantly, and remarkable decrease of blood glucose was shown in the Y.S.T. (12.5ml/kg) dosed group, after 4weeks of experiment. 2. The volume of total cholesterol of blood serum was decreased notably, especially remarkable reduce of total cholesterol was shown in the Y.S.T. (12.5ml/kg) dosed group after a week. 3. The volume of triglyceride in the blood serum of diabetic rats, induced by the streptozotocin was decreased after 4 weeks, and remarkable decrease was shown in the Y.S.T. (12.5ml/kg) dosed group after 2 weeks of experiment. 4. The volume of the phospholipid in the diabetes rats, was decreased significantly in the Y.S.T. (12.5ml/kg) dosed group after 2 weeks of experiment. 5. The volume of total protein of diabetes rats, was increased in all group, and the remarkable increase was shown in the Y.S.T. (12.5ml/kg) dosed group after 4 weeks. 6. The volume of the sodium in the Y.S.T. (12.5ml/kg) dosed group, was notable in each Y.S.T. dosed group (1.25ml/kg, 12.5ml/kg) after a week experiment. According to above results, It is expected that Y.S.T. applied to SOYANGIN, can be used for medical treatment of diabetes with effect. But because the effect can be somewhat different depending upon dosage, appropriate operation on clinic is needed, for the best curing effect.

We investigated the association of Chlorella vulgaris and E. coli W9110 in removal of total organic carbon with the lab-scaled continuous river water flow system (CRWFS). Artificial wastewater was applied at two levels of organic carbon concentration; 1,335 $mg{\cdot}l^{-1}$ in the treatment (T)-1 and 267 $mg{\cdot}l^{-1}$ in T-2. The highest densities of C. vulgaris were $8.3{\times10^6\;cells{\cdot}ml^{-1}$ in T-1 and $6.9{\times}10^6\;cells{\cdot}ml^{-1}$ in T-2. The maximum densities of E. coli W3110 were $2.0{\times}10^8$ clony forming unit (CFU)${\cdot}ml^{-1}$ in T-1 and $3.9{\times}10^8\;CFU{\cdot}ml^{-1}$ in T-2. The densities increased during the first 11 days in T-q and 4 days in T-2, and decreased rapidly till 35th day, then increased slightly afterwards. This trend was prominent in T-2. It was inplied that wider range of nutrients was required in the growth of heterotrophic bacteria in T-2 than in T-1. The algal biomass should be increased effectively for the successful removal of organic carbon.
