        개에서의 indocyanine green 배설시험 및 혈장효소 활성치의 변화

        김철호,최일관,손민수,김진구,강정부,Kim, Cheol-ho,Choi, Il-kwan,Son, Min-soo,Kim, Jin-gu,Kang, Chung-boo 대한수의학회 1992 大韓獸醫學會誌 Vol.32 No.4

        This experiment was carried out to establish a proper method of indocyanine green(ICG) excretion test for a applicable liver function test in dogs. The half life(T1/2), fractional clearance rate(KICG) and retention rate after injection of ICG with or without administred carbon tetrachloride($CCl_4$) were also invested. The results obtained were as follows ; 1. The maximum absorbance of ICG in plasma was at 810nm. 2. Half life and fractional clearance rate when administered 0.25 and 0.50mg of ICG per Kilogram body weight were $6.33{\pm}0.58$ minutes and $0.11{\pm}0.99$/minute in the former, $10.01{\pm}1.0$ minutes and $0.07{\pm}0.007$/minute in the latter, respectively. The ICG removal rate was exponentially linear for the first 15 minutes after injection both, of 0.25 and 0.50mg of ICG. 3. One day following the administration of $0.0042m{\ell}\;CCl_4$ kilogram body weight which injected 0.50mg of ICG, half life was more longer and fractional clearance rate was significantly reduced than that of ICG single injection. 4. Plasma retention rate when 15, 30, 45 minutes after injection dose of 0.25 and 0.50mg ICG per Kilogram body weight, $14.7{\pm}4.8$, $5.1{\pm}3.1$, $2.6{\pm}1.6%$ in the former, $26.9{\pm}1.8$, $11.1{\pm}2.4$, $4.8{\pm}1.3%$ in the latter, respectively. However, after administration of $CCl_4$, plasma retention rate of ICG at a dose of 0.50mg, it was $39.3{\pm}0.9$, $16{\pm}2.9$, $10.7{\pm}0.1%$, respectively. 5. Plasma enzyme(AST, ALT, r-GTP) activities administered with $CCl_4$ were increased, but there was no change which injected any dose of single ICG injection. From these results, ICG excretion test to dog is applicable to evaluation of liver function in both clinical and research.

        Progesterone 측정을 위한 액상(液相) 효소면역측정법(酵素免疫測定法)의 최적조건에 관한 연구

        강정부,최일관,손민수,허주형,김철호,Kang, Chung-boo,Choi, Il-kwan,Son, Min-soo,Hur, Ju-hyeong,Kim, Chur-ho 대한수의학회 1992 大韓獸醫學會誌 Vol.32 No.3

        This study was carried out to develop an effective liquid-phase double antibody enzyme immunoassay for determining of progesterone. The optimum conditions of assay system, 1st and 2nd antibodies, enzyme conjugate, and time reaction were invested. The bovine plasma progesterone level in dairy cattle and korean native bulls were also analyzed. The results obtained were as follows; 1. The reproducibility of petroleum ether was superior to that of ethyl ether as extract solvent of progesterone in plasma. 2. The optimum dilution rate of 1st and 2nd antibody was 30,000 and 10 times, respectively. Affer the reaction of enzyme conjugate to progesterone 1st antibody, and then 2nd antibody competition reaction was enough for over 1hr. 3. Average plasma progesterone level in 4 pregnant and 9 nonpregnant Holstein was $2.5{\pm}0.5$ and $0.7{\pm}0.2ng/m{\ell}$, respectively. Average plasma progesterone level of 10 Korean native bulls was $0.1{\pm}0.001ng/m{\ell}$ From these results, by using liquid phase double antibody enzyme immunoassay for progesterone is applicable to detect of early pregnancy diagnosis, factorial analysis of reproductive disorder, and also reproductive physiological function such as monitoring of cyclicity during the post-partum period.

        한우 및 유우에서의 indocyanine green 배설시험 및 혈장효소 활성치의 변화

        손민수,김철호,최일관,김진구,허주형,강정부,Son, Min-soo,Kim, Cheol-ho,Choi, IL-kwan,Kim, Jin-gu,Hur, Ju-hyeong,Kang, Chung-boo 대한수의학회 1992 大韓獸醫學會誌 Vol.32 No.4

        This experiment was carried out to establish a proper method of indocyanine green(ICG) excrection test for a applicable liver function test in three Korean native cattle average weighing about 450kg and dairy cattle parity of 3~5. The results obtained the half life($T^1/_2$), fractional clearance rate(KICG), retention rate and plasma enzyme activities before or after injection of ICG were as follows. 1. The maximum absorbance of ICG in plasma was at 805nm. 2. Average half life and fractional clearance rate following the injection of ICG 0.25mg/kg body weight were $5.53{\pm}1.27$ minute and $0.131{\pm}0.031$/minute in Korean native cattle, $4.55{\pm}0.68$ minute and $0.156{\pm}0.031$/minute in dairy cattle, respectively. The ICG removal rate was exponentially liner for the first 15 minutes after injection both of Korean native cattle and dairy cattle. 3. Average plasma retention rate when 10, 15, 30 minutes after injection was $35.7{\pm}13.9$, $23.2{\pm}7.1$, $10.8{\pm}3.5%$ in Korean native cattle, $26.8{\pm}3.3$, $14.2{\pm}1.2$, $5.5{\pm}2.2%$ in dairy cattle, respectively. 4. Plasma enzyme activities(AST, ALT, r-GTP) were no variation among the before, during and after injection of ICG. From these results, ICG excretion test to cattle is applicable to evaluation of liver funtion in both clinical and research, and adopted the 15 minutes plasma sample as the sample taken at the ideal time for comparative purposes.
