        N/A Objectives : Diabetic autonomic neuropathy is a common complication of long standing diabetes mellitus and is well known to induce the motor dysfunction of cardiovascular system, genitourinary system and digestive system. Although many studies have done to evaluate the diabetic autonomic neuropathy, gallbladder motor function and biliary dynamic study to evaluate the change of gallbladder function in diabetic patients is relatively rare. This study was performed to measure the gallbladder ejection fraction using Tc- 99m-DISIDA with fatty meal in order to evaluate the gallbladder motor function in diabetic patients and to examine the usefulness of it in analyzing diabetic autonomic neuropathy. Methods : 51 diabetic patients(males 31, females 18, mean age 57yr(36-77yr)) and 1H control subjects(males 14, females 4, mean aged 47yr(31-70yr)) without gallstone and impaired liver function were enrolled in our study. Also the diabetic patients were categorized by age, disease duration, body weight and diabetic complications such as retinopathy, peripheral neuropathy and cardiovascular autonomic neuropathy accompanying with or not. Results : 1) Median value and interquartile range of gallbladder ejection fraction(%) were 66%(48-79%) in diabetic patients group and 75%(64-80%) in control subjects. There was no statistically significant difference between the two groups, but the mean value of diabetic patients was slightly lower than that of control subjects. 2) There was no significant difference between the two groups in mean value of gallbladder ejection fraction in every age group(P>0.05). 3) Median value of gallbladder ejection fraction in diabetic groups with less than 10 years of duration (both under 5 years and 5 to 10 years groups) was similar to that of control subjects. However in patients whose diabetic conditions last more than 10 years, the median range of gallbladder ejection fraction was significantly lower than that of control subjects(P<0.05). 4) Median range of gallbladder ejection fraction in obese diabetic patients group was significant lower than those of control subjects and non- obese diabetic patients(p<O.C6). 5) Median value of gallbadder was lower in diabetic patients group with complications like retinopathy, peripheral neuropathy or cardiovascular autonomic neuropathy (p<0.05) in comparison with those of control subjects and diabetic patients group without diabetic complication (p>0.05). Also seven diabetic patients whose gallhladder ejection fraction was reduced under,35% have had at least two diabetic complications. Conclusion : We observed that gallbladder ejection fraction of diabetic patients was reduced compared with that of control subjects. This is due to the reduced gallbladder muscle contractility resulting from diabetic autonomic dysfunction. These results suggest that the assessment of gallbladder ejection fraction using 99m- Tc-DISIDA would be useful to diagnose diabetic autonomic neropathy.

        비이온성 및 양쪽 이온성 계면활성제 첨가가 반추위 혼합 미생물의 성장과 볏짚의 in vitro 소화에 미치는 영향

        이신자(Shin Ja Lee),김완영(Wan Young Kim),문여황(Yea Hwang Moon),김현섭(Hyeon Shup Kim),김경훈(Kyoung Hoon Kim),하종규(Jong Kyu Ha),이성실(Sung Sill Lee) 한국생명과학회 2008 생명과학회지 Vol.18 No.4

        본 연구는 반추위 미생물 발효에 있어서 계면활성제의 이온성 여부가 발효시간별 in vitro 건물소화율, 미생물 성장량, pH 변화, Gas 발생량 및 SEM에 의한 미생물 부착 양상을 조사하기 위해 수행되었다. 1 ㎜ 입자도의 볏짚을 기질로 하여 Holstein 젖소 위액을 이용한 Dehority's artificial medium에 대조구를 비롯하여 비이온성 계면활성제(NIS)로서 시판되고 있는 Tween 80과 SOLFA-850 2종류, 그리고 양쪽(+/-) 이온성 계면활성제(ZIS)로서 3-(Dodecyldimethyla㎜onio) propanesulfanate (DDAP) 1 종류를 이용하여 각각 0.05% 및 0.1% 수준으로 첨가함으로써 총 7처리를 두었다. 발효시간은 6, 12, 24, 48 및 72시간으로 설정하여 각 처리 당 3반복으로 시험을 수행하였다. In vitro 건물 소화율은 NIS인 Tween 80 첨가구에서 48시간 및 72시간 발효 시, 타 처리구에 비해 유의적(P<0.05)으로 높았으나, ZIS인 DDAP 첨가구는 발효 24시간이후 부터 대조구보다도 건물소화율이 낮게 나타났다(P< 0.05). 가스 발생량은 NIS 두 처리구 모두, 대조구나 ZIS 처리구보다 유의적(P<0.05)으로 많았으며, 발효시간의 경과함에 따라 증가하였다. 미생물 성장량은 NIS인 Tween 80 첨가구에서 가장 많았고, 다음으로 SOLFA 850 첨가구 순이었으며, ZIS인 DDAP 첨가구는 대조구보다도 적었다(P<0.05). 전자현미경으로 관찰한 미생물 부착 양상에서 NIS 첨가구는 무처리구에 비해 미생물 군집이 현저히 많았으나 ZIS 첨가구는 오히려 적은 것으로 나타났다. 따라서 양쪽(+/-) 이온성 계면활성제는 반추위 발효 작용과 미생물 성장에 긍정적인 효과가 없는 것으로 사료된다. This experiment was conducted to investigate effects of non-ionic or zwitterionic (+/-) surfactants on digestibility of rice straw, and changes of growth of rumen mixed microbes, pH, and gas production during in vitro fermentation. Also, during in vitro ruminal fermentation, microbial attachment on rice straw was investigated using scanning electron microscopy (SEM). Tween 80 or SOLFA-850 for non-ionic surfactant (NIS), and 3-(Dodecyldimethylammonio) propanesulfanate (DDAP) for zwitterionic surfactant (ZIS) was supplemented by 0.05% and 0.1% in Dehority's artificial medium containing Holtein rumen fluid, respectively, and the substrate for fermentation was rice straw passed through 1 mm screen. The experiment was composed of 7 treatments (two levels of two NISs, two levels of a ZIS) including the control, and 6, 12, 24, 48 and 72 hr of fermentation time with 3 replications per treatment. Treatment of Tween 80 increased in vitro DM digestibilities during 48 hr and 72 h post fermentations compared to the other treatments, whereas treatment of DDAP as a ZIS resulted in decreased DM digestibility than that of the control from 24 hr post fermentation (P<0.05). Gas production in vitro was greater (P<0.05) with addition of NIS than the control or ZIS, and increased as fermentation time elapsed. Rumen mixed microbial growth was greatest with addition of Tween 80 as NIS, and lowest when DDAP as ZIS was supplemented to the fermentation tube (P<0.05). In SEM observation, rumen microbial population attached on rice straw particle was greater with addition of NIS, but was less with addition ZIS compared with the control. In conclusion we could not found any positive effects of ZIS surfactants on rumunal fermentation characteristics and rumen microbial growth rates.

        비이온성 계면활성제 Tween 80의 첨가가 반추위 혼합 미생물에 의한 in vitro 가스발생량, 건물소화율, 효소활력 및 미생물 성장율에 미치는 영향

        이신자(Shin Ja Lee),김완영(Wan Young Kim),문여황(Yea Hwang Moon),김현섭(Hyeon Shup Kim),김경훈(Kyoung Hoon Kim),하종규(Jong Kyu Ha),이성실(Sung Sill Lee) 한국생명과학회 2007 생명과학회지 Vol.17 No.12

        비이온성 계면활성제(non-ionic surfactant: NIS) Tween 80의 첨가가 gas 발생량, 각종 기질의 건물 소화율, 섬유소 분해효소의 활력, 미생물 성장률 그리고 미생물의 기질 부착성에 미치는 영향을 규명하기 위하여 볏짚, 알팔파 건초, filter paper 그리고 톨페스큐 건초를 공시하여 in vitro 시험을 수행하였다. NIS Tween 80을 0.05% (v/v) 수준으로 배지에 첨가하였을 때, in vitro 건물 소화율, cumulative gas 생성량, 미생물 성장량 그리고 섬유소 분해효소의 활력 등 조사항목 모두가 모든 공시된 기질에서 유의적 (P<0.05)으로 증가하였다. 볏짚, 알팔파 건초, filter paper 및 톨페스큐 건초로부터 발생된 in vitro 48시간 배양후의 가스량이 NIS의 첨가로 인하여 무처리구에 비하여 각각 274.8, 235.2, 231.1 및 719.5% 가 유의적(P<0.05)으로 증가하였다. Tween 80을 0.05% 수준으로 알팔파 건초 기질에 첨가하여 배양 36시간 후에 섬유소 분해효소의 활력을 측정 하였을 때, Avicelase의 경우는 무첨가구와 비교하여 변화가 없었지만 CMCase, xylanase 및 amylase의 활력은 무처리구에 비해 각각 38.1, 121.4 및 38.2%가 증가하였다. 이러한 결과들은 호기성 미생물에서와는 달리 Tween 80을 0.05% 수준으로 배지에 첨가하면 혐기성 미생물의 성장률을 감소시키지 않고 오히려 증가시키며 여러 종류의 섬유소 분해효소의 분비가 촉진될 수 있다는 것을 시사하는 것이다. 전자현미경(SEM) 관찰결과 NIS Tween 80의 첨가가 미생물의 기질 부착성을 증가시키지는 못하였다. 따라서 NIS Tween 80의 첨가로 가스발생량과 in vitro 건물 소화율 그리고 섬유소 분해효소의 활력이 증가한 이유는 미생물의 기질 부착성 때문이 아니라는 것을 알 수 있다. The non-ionic surfactant (NIS) Tween 80 was evaluated for its ability to influence in vitro cumulative gas production, dry matter digestibility, cellulolytic enzyme activities, anaerobic microbial growth rates, and adhesion to substrates by mixed rumen microorganisms on rice straw, alfalfa hay, cellulose filter paper and tall fescue hay. The addition of NIS Tween 80 at a level of 0.05% increased significantly (P<0.05) in vitro DM digestibility, cumulative gas production, microbial growth rate and cellulolytic enzyme activity from all of substrates used in this study. In vitro cumulative gas production from the NIS-treated substrates; rice straw, alfalfa hay, filter paper and tall fescue hay was significantly (P<0.05) improved by 274.8, 235.2, 231.1 and 719.5% compared with the control, when substrates were incubated for 48 hr in in vitro. The addition of 0.05% NIS Tween 80 to cultures growing on alfalfa hay resulted in a significant increase in CMCase (38.1%), xylanase (121.4%), Avicelase (not changed) and amylase (38.2%) activities after 36 h incubation. These results indicated that the addition of 0.05% Tween 80 could greatly stimulate the release of some kinds of cellulolytic enzymes without decreasing cell growth rate in contrast to trends reported with aerobic microorganism. Our SEM observation showed that NIS Tween 80 did not influence the microbial adhesion to substrates used in the study. Present data clearly show that improved gas production, DM digestibility and cellulolytic enzyme activity by Tween 80 is not due to increased bacterial adhesion on the substrates.

      • In Vitro Growth of Bovine Preantral Follicle under Different Culture Conditions

        Lim, Hyun-Joo,Kim, Dong-Hoon,Im, Gi-Sun,Hwang, Seong-Soo,Baek, Kwang-Soo,Jeon, Byeong-Soon,Park, Sung-Jai,Kim, Hyeon-Shup,Lim, Jeong-Mook The Korean Society of Animal Reproduction 2009 Reproductive & developmental biology Vol.33 No.4

        The objective of this study was to determine effects of different culture media. Preantral follicles were mechanically extracted from bovine ovaries and cultured for 16 days in tissue culture medium (TCM)-199, DMEM or alpha-minimal essential medium ($\alpha$-MEM) + 10% FBS + 0.1 mg/ml sodium pyruvate + 100 mIU/ml FSH. The collected primary follicles from ovary were higher than the primary and secondary follicles. The survival rates of the follicles in TCM-199 were significantly higher (p<0.05) than those in DMEM and $\alpha$-MEM. The diameter of the follicles progressively increased during 12 days of culture. The maximum size ($139.1{\pm}5.4\;{\mu}m$) reached on Day 12 of the in vitro culture and decreased on Day 16. These results suggest that in a culture of bovine preantral follicles, TCM-199 is an optimal medium and a longer-term culture of preantral follicles (>12 days) may be needed to form antra.

        기계적합금법에 의해 제조된 TiNi합금의 수소화반응특성에 관한 연구

        안효준(Hyo Jun Ahn),김보수(Bo Su Kim),황진환(Jin Hwan Hwang),안인섭(In Shup Ahn),김기원(Ki Won Kim),허보영(Bo Young Hur) 한국수소및신에너지학회 1994 한국수소 및 신에너지학회논문집 Vol.5 No.2

        The hydrogenation behavior of Ti-Ni powders prepared by mechanical alloying in a high energy ball mill have been investigated by P-C isotherm curves, DSC(differential scanning calorimetry), X-ray diffractometer, SEM(scanning electron microscope). Amorphous TiNi phase was formed after 10 milling hours. The hydrogen storage capacity gradually decreased as a function of mechanical alloying time. There appears the DSC endothermic peak due to hydrogen evolution of amorphous hydride phase.

        하안검의 종괴로 발현된 전이성 위암 1 예

        김학수,최병진,차주영,류광현,한신,김소연,황인섭,시석,박병익,조민구 대한내과학회 1998 대한내과학회지 Vol.54 No.4

        Eyelid tumors, including metastatic lid tumors, present clinically as recurrent chalazia, multicentric nodules, ulcerated lesions, diffuse swelling, or chronic blepharoconjuntivitis. Lid tumors consist of benign lesions(69%) and malignant lesions(31%). Basal cell carcinoma and squamous cell carcinoma account for 92% of the malignant lesions. Metastatic lid disease was found to be of rare occurence, accounting for 0.1% of all lid lesions and 0.3% of malignant lid lesions. We report a case of metastatic lid carcinoma of stomach cancer. A 60-year-old man developed a painless, slow-growing nodular lesion of his right lower eyelid. Excisional biopsy revealed metastatic undifferentiated adenocarcinoma. We believe this is the first case in Korean literature.
