Thiopental sodium is known as ultrashort-acting barbiturates and can be employed advantageously for numerous conditions. But thiopental has the side effects of cardiovascular and respiratory systems which has barbiturates and are depend on the dose of thiopental. The side effects are reduced when the thiopental is preceded by a tranquilizer and sedative. In these drugs, benzodiazepines have the minimal effects of cardiovascular and respiratory systems. In this study, the effects of midazolam preanesthetic administration, followed by thiopental anesthetic induction, on cardiovascular system and thiopental induction requirement were studied in 14 mixed breed dogs. Cardiovascular data were recorded baseline, after premedication of saline 0.45 ml/kg or midazolam 0.1, 0.2, 0.4, 0.8 mg/kg, intubation, and 5, 10, 15, 20, 30 minutes after intubation. Extubation, head-up, sternal recombency, standing, and walking recovery times were recorded. The results were summarized as follows; (1) The 0.1, 0.2, 0.4, and 0.8 mg/kg dosages of midazolam insignificantly decreased thiopental dose requirement necessary to accomplish intubation by 6, 20, 21 and 28%. (2) The 0.1, 0.2, 0.4, and 0.8 mg/kg dosages of midazolam insignificantly reduced the times of extubation, head-up, sternal recumbency, standing, and walking recovery. (3) Midazolam was effective in reducing the frequency and duration of arrhythmia after intubation. (4) Heart rates of preanestheic midazolam administraion groups increased after thiopental injection which insignificantly changed smaller than those of control group. (5) Arterial blood pressures did not vary significantly among groups.

Despite many studies, results of superovulation protocols are not consistent in farm animals. In this study, 151 Boer goats were superovulated to examine the factors affecting superovulation and embryo transfer (MOET). An optimal regime for superovulation treatment was identified as a 4-day treatment with decreasing dosages of 6-7 mg Chinese FSH or 240 mg Canadian FSH. The 4-day treatment with decreasing dosages of 6-7 mg Chinese FSH was, therefore, adopted to study effects of the age of does, season and repeated treatments on superovulation and embryo transfer. The best season for superovulation and embryo transfer and pregnancy was autumn, and the best age range was 12-35 months old. Within animals there were no significant differences in the number of ovulations and the rate of transferable embryos between the first and the second superovulation. However, these parameters declined significantly for the third superovulation. No marked effects of the number of ovulations on the proportion of transferable embryos were noted. The parturition rate of the recipients receiving single embryos was not different significantly from those receiving two embryos, and the kidding rate calculated from embryos transferred did not differ significantly between recipients receiving one and two embryos.

The net photosynthetic rate of 'Seolhyang' strawberry plants was measured daily for 7 days after treatment at three UV illumination dosages (0, 9.8, and 29.5 $kJ{\cdot}m^{-2}$). The net photosynthetic rates of the strawberry plants with 9.8 and 29.5 $kJ{\cdot}m^{-2}$ UV light illumination decreased by 20.2 and 61.4%, respectively, at 7 days after UV light treatments. UV treatments with two illumination dosages (7.9 and 15.7 $kJ{\cdot}m^{-2}$) altered the phenolic compounds contents during the cultivation period when compared to those in the control fruits. The anthocyanin content with 7.9 $kJ{\cdot}m^{-2}$ UV light illumination of 'Seolhyang' increased by 18.7% compared with those in control fruits at the 11 DAT. However, the anthocyanin content of 'Maehyang' was not significantly different among treatments during experiment period. The highest level of ellagic acid was found with 7.9 $kJ{\cdot}m^{-2}$ UV light illumination in both cultivars at the 11 DAT. Our results showed that strawberries illuminated with UV light during cultivation period had higher bioactive compounds contents than control fruits. These results suggest that UV light treatments may be a useful non-chemical way of promoting strawberry fruits quality.

The advanced oxidation process (AOP) using ozone combined with hydrogen peroxide and ultraviolet treatment were evaluated for biodegradable dissolved organic carbon (EDOC) formation and dissolved organic carbon (DOC) removal. Oxidation treatment were conducted alone or combination with ozone, hydrogen peroxide and ultraviolet processes. Ozone dosage of ozone process was varied from $0.5mg/l{\ell}\cdot}min$ to $5mg/{\ell}{\cdot}min$. Ozone/hydrogen peroxide process was done using $20mg/{\ell}{\cdot}min$ of hydrogen peroxide concentration. Ozone/ultraviolet process was irradiated with $12mW/cm^2$ of density and 254nm. Ozone dosage was varied from $0.5mg/{\ell}{\cdot}min$ to $5mg/{\ell}{\cdot}min$ at the ozone/hydrogen peroxide and ozone/ultraviolet processes too. Contact time of all the process was 20 minutes. Oxidation treatment were performed on microfiltration effluent samples. BDOC formation was reached to an optimum at ozone dosage of $1.5mg/{\ell}{\cdot}min$ in the ozone/hydrogen peroxide process and $1mg/{\ell}{\cdot}min$ in ozone/ultraviolet process, after which BDOC formation was decreased at higher ozone dosages. But BDOC formation was increased with ozone dosages increasing in ozone process. The efficiency of DOC removal was higher AOPs than ozone process. Ozone/ultraviolet proces was the highest for DOC removal efficiency in each process. THMFP. removal efficiency by ozone/ultraviolet process was higher than that by each of ozone process and ozone/hydrogen peroxide process.

This research was conducted to determine effect of pumice aggregate ratio, cement dosage and slumps on freeze-thaw resistance, density, water absorption and elasticity of concrete. In the first batch, $300kg/m^3$ cement dosage were kept constant and pumice ratios were changed as 25%, 50%, 75% and 100% of replacement for normal aggregate by volume for $3{\pm}1cm$, $5{\pm}1cm$ and $7{\pm}1cm$ slumps. Other batches were prepared with $200kg/m^3$, $250kg/m^3$, $350kg/m^3$, $400kg/m^3$ and $500kg/m^3$ cement dosages and 25% pumice aggregate +75% normal aggregate at a constant slump. Test results showed that when pumice-aggregate ratio decreased the density and freeze-thaw resistance of concretes increased. With increasing of cement dosage in the mixtures, density of the concretes increased, however, freeze-thaw resistance of concretes decreased. Water absorption of the concrete decreased with increasing cement dosage but increased with the pumice ratio. Water absorption of the concrete also decreased after freeze-thaw cycles. Freeze-thaw resistance of concretes was decreased with increasing the slumps.

The effect of DHU001, a mixed herbal formula consisted of 7 types aqueous extracts for various respiratory disorders were evaluated on 2,4-dinitrofluorobenzene (DNFB)-induced contact dermatitis, type I allergic model. Contact dermatitis was induced by sensitization with dinitrophenyl-derivatized ovalbumin (DNP-OVA) and DNFB challenge as antigen. Two different dosages of DHU001 (300 and 150 mg/kg) were orally administered to DNP-OVA sensitization mice once a day for 7 days with reference material, dexamethasone (15 mg/kg, intraperitoneal treatment). End of 7 days oral administration of DHU001 extracts or intraperitoneal treatment of dexamethasone, the changes on the edematous changes and scratching behavior were measured. Immediate after DNFB challenge on ear or paw of DNP-OVA sensitized mice, increases of ear and paw thicknesses and weights were detected with anterior ear skin (dermis to epidermis) thickness and paw scratching behavior increases. However, these contact dermatitis signs induced by DNFB treatment were reduced by treatment of the both different dosages of DHU001 and dexamethasone, respectively. The results obtained in this study suggest that oral treatment of DHU001 extracts also has relatively favorable effects on contact dermatitis.

Objectives : This study aims to propose a processing method for dosage units of medicinal materials and the database schema to manage formula data in Korean medicine ontology. Methods : All dosage units of medicinal materials are collected from the seven textbooks that contain formula data of Korea medicine ontology. Dosages are converted to Arabic numerals and units that are frequently used are converted to representative units. Database schema is designed for processing and managing the formulas and medicinal materials with dosage units. Results : Seven representative units are selected out of 77 units. They will be used in the addition or subtraction of medicinal materials in a formula support system. The remaining units will be made available for references. Conclusions : EMR or chart programs used in clinical hospitals contain formula data that is already standardized. However, the formula data in Korean medicine literature and textbook is not refined, so it is necessary to process the dosages and units of medicinal materials to use in the formula support system. This result is a processing method to utilize the formula data of Korean medicine textbooks and it will be implemented this method in the established formula support system in the future.

고양이에서 납의 중독량을 결정하고 행동과 임상병리학적인 변화를 밝히고, 납 투여용량과 혈중 납농도와의 관계를 규명하기 위하여 42마리의 고양이를 대상으로 체중에 따라 0(대조군), 10, 100(저용량), 1000, 2000, 4000(고용량) ppm의 lead acetate를 경구적으로 투여하여 납독성을 평가하였다. 고투여용량(1000, 2000, 4000ppm)을 투여한 어떤 고양이는 분출성 구토, 활동항진 그리고 발작을 보였다. 모든 실험군에서 성장율은 변화가 없었다. 고양이의 정상 혈중 납농도는 사람, 개 그리고 소의 혈중 납농도 보다 낮았다. 고양이에서 준임상형 납중독의 혈중 납농도는 3~20$\mu\textrm{g}$/100$m\ell$이었고, 임상형 납중독의 혈중 납농도는 20~l20$\mu\textrm{g}$/100$m\ell$이었다. Zinc protoporphyrin 농도는 납 투여용량에 비례하였으며 50$\mu\textrm{g}$/100$m\ell$ 이상으로 ZPP농도가 유의성 있게 증가하는 경우는 임상형의 납중독을 의미하였다. Aminolevulinic acid dehydratase는 모든 납 투여용량에 역비례 관계를 보였고, 고양이의 납노출에 대한 유용한 진단적 지표로 나타났다. 오줌의 aminolevulinic acid 농도는 대개 납투여용량에 따라서 증가하지만 측정치는 개체에 따라 다양하였다. 피모의 납농도는 납투여용량에 따라 비례적으로 증가하였다. 최소한 고용량에서 납은 PMN세포와 단핵구의 화학주성을 억제하는 것으로 나타났다. 헤모글로빈, 적혈구, 백혈구, 호중구, 임파구, 단핵구 그리고 호산구에서는 투여용량에 대한 반응이 일정하게 관찰되지 않았고 또한 총단백, 혈장단백, BUN그리고 ALT치에서의 용량에 따른 일정한 변화가 없었다. 망상적혈구수는 대부분의 납투여용량수준에서 유의성 있게 증가하지 않았기 때문에 고양이 납중독의 진단적 가치는 거의 없었다. 신경전달속도의 유의성 있는 변화가 없는 것으로 보아 납섭취로 인한 대상성 탈여(Segmental demyelination)는 없는 것으로 생각된다. 고양이의 치사량은 체중 kg당 60~150mg이었다. 납중독 진단에 신뢰할 수 있는 파라미터는 혈중 납농도, ZPP. ALAD 그리고 피모의 납농도이었다.
