  • 본 연구는 급성 납 독성에 대한 활성탄의 방어효과를 알아보기 위하여 시도되었다. 30g 내외의 생쥐를 대상으로 대조군, 납(60mg/kg)투여군, 납 투여후 활성탄(40mg/kg)투여군으로 구분하여 구강투여 한 후 신장 손상억제 효과를 알아보기 위하여 생화학적 및 조직학적 실험을 실시하였다. 혈액 중 blood urea nitrogen(BUN) 그리고 creatinine (Cre)의 활성도는 활성탄 투여군이 납 투여군보다 감소되었다. 전자현미경적 관찰 결과, 신장의 근위세뇨관에서 납 투여군은 미세융모의 소실이 나타나고, 핵이 함입되어 불규칙해졌으며, 미토콘드리아는 팽대되고, 그 수가 감소하였다. rER의 수조가 확장되고 공포화 현상이 관찰되었으며 리보솜의 탈락이 관찰되었다. 활성탄 투여군은 핵은 거의 원형의 상태이고, 다수의 미토콘드리아가 관찰되었으며, rER은 리보솜이 부착된 상태로 관찰되었다. 이상과 같은 결과, 활성탄이 납 중독된 생쥐에서 납을 흡착시킴으로서 손상된 신장에 보호 효과가 있는 것으로 사료된다.

  • Objectives This study is to investigate whether oral administration of Farfarae flos, JCT (Jeong-cheon-tang), CPT (Cheong-pye-tang) and CPK (Cheong-pye-tang- ga-kwandonghwa) will affect both the levels of serum GOT, GPT, blood urea nitrogen (BUN) and creatinine in SD rats or not, and will change body weight of the rats. Materials and Methods 18 SD rats were randomly divided into 6 groups - including a control group (vehicle 2 ml/rat), Farfarae flos water extract (extract 2 ml/rat), Farfarae flos fine powder (emulsion 2 ml/rat), JCT (extract 2 ml/rat), CPT (extract 2 ml/rat) and CPK (extract 2 ml/rat) group. The drugs were administered to rats for 2 weeks or 30 days (for control and Farfarae flos fine powder group only) and serum GOT/GPT activities and BUN/creatinine concentrations were measured. Also, the changes of body weights of each rat was measured. Results (1) Farfarae flos water extract, Farfarae flos fine powder emulsion, JCT and CPT and CPK did not cause any changes in serum GOT/GPT activities and BUN/creatinine concentrations compared to the ones in control group. (2) There are no significant changes in rats' body weight among the experimental groups during the experimental period. Conclusions Contrary to the reports on human data, 2 weeks or 30 days of oral administrations of Farfarae flos itself and decoctions containing Farfarae flos did not provoke hepatotoxicity and nephrotoxicity.

  • Paecilomyces sinclairiis (PS) is known as a functional food or human health supplement. However concerns have been raised about its kidney toxicity. This study was performed to investigate the kidney toxicity of PS by 13 week-oral administration to rats. Blood urea nitrogen (BUN), serum creatinine, and kidney damage biomarkers including beta-2-microglobulin (${\beta}2m$), glutathione S-transferase alpha (GST-${\alpha}$), kidney injury molecule 1 (KIM-1), tissue inhibitor of matrix metalloproteinase 1 (TIMP-1), vascular endothelial growth factor (VEGF), calbindin, clusterin, cystatin C, neutrophil gelatinase-associated lipocalin (NGAL) and osteopontin were measured during or after the treatment of PS. BUN, creatinine and kidney damage biomarkers in serum were not changed by PS. However, kidney cell karyomegaly and tubular hypertrophy were observed dose-dependently with higher severity in males. KIM-1, TIMP-1 and osteopontin in kidney and urine were increased dose dependently in male or at the highest dose in female rats. Increased urinary osteopontin by PS was not recovered at 2 weeks of post-exposure in both genders. Cystatin C in kidney was decreased at all treatment groups but inversely increased in urine. The changes in kidney damage biomarkers were more remarkable in male than female rats. These data indicate that the PS may provoke renal cell damage and glomerular filtration dysfunction in rats with histopathological lesions and change of kidney damage biomarkers in kidney or urine. Kidney and urinary KIM-1 and cystatin C were the most marked indicators, while kidney weight, BUN and creatinine and kidney damage biomarkers in serum were not influenced.

  • The aims of this study were to analyze canine pyometra cases at Veterinary Medical Center of Chungbuk National University, and to identify prognostic factors of canine pyometra at the stage of diagnosis. Records of cases about intact female dogs presented to Veterinary Medical Center from 2005 to 2019 were used for analysis. A total of 147 intact female dogs with canine pyometra were analyzed from outpatients' caseload. Median outbreak age was 9.6 years (range, 8 months to 17 years). The highest prevalence of pyometra over 14 years was observed in Maltese (22.4%, n = 33). Urologic disorders (21.8%, n = 32) including acute renal failure and cystic calculi were the most frequently observed concurrent disorders in dogs with pyometra. In other cases of pyometra, tumor (15.0%, n = 29), cardiovascular disorders (15.0%, n = 22) and systemic disorders (10.9%, n = 16) were accompanied with pyometra. The concentrations of BUN, creatinine and glucose were higher than reference range in cases of poor prognosis. According to the binominal logistic regression analysis, prognosis in pyometra was related to abdominal distension (p = 0.036), urologic disorder (p = 0.016), gastrointestinal disorder (p = 0.001), and serum level of blood urea nitrogen (BUN) (p = 0.045). This study describes that prognosis of canine pyometra can be predicted at the stage of diagnosis by abdominal distension, urologic disorder, gastrointestinal disorder, and serum level of BUN.

  • The purpose of this study was to evaluate the nutritional status and to identify related factors in elderly hemodialysis patients. Sixty-four patients who were registered in Asan Medical Center, Seoul, Korea, participated in the study. The data was collected between September and December, 2003. General characteristics were obtained with the use of an interviewer-administered questionnaire. Anthropometric and biochemical data, 3-day dietary records and dietary habits were also obtained. The results of this study were analyzed with t-test or $X^2$-test using SPSS package program. The percentage of elderly hemodialysis patients who were undergoing mild to severe malnutrition (MN group) and were normal nutrition (NN group) by subjective global assessment (SGA) criteria were 46.9% and 53.1 %, respectively. Appetite (p < 0.05) and dietary cholesterol intakes (p < 0.05) were significantly lower in MN group than the NN group. Body mass index (BMI, p < 0.001), lean body mass (LBM, p < 0.05), triceps skinfold thickness (TSF, p < 0.01), mid ann circumference (MAC, p < 0.01) and mid ann muscle circumference (MAMC, p < 0.05) were also lower in the MN group than the NN group. There were also significant differences in blood urea nitrogen (BUN, p < 0.05), creatinine (p < 0.05), prealbumin (p < 0.001) and C-reactive protein (CRP, p < 0.05). SGA was negatively correlated with serum BUN, creatinine and pre albumin, dry weight, BMI, LBM, total body water, TSF, MAC and MAMC, and positively correlated with age. In stepwise multiple regression analysis, SGA was related to BMI, CRP, age and BUN. In conclusion, almost half of the subjects were in malnourished status and had lower values in anthropometric and biochemical data. Our results suggest that SGA is a simple and adequate method for assessing the nutritional status in elderly hemodialysis patients and adequate dietary guidelines based on individual nutritional status are needed in the patients.

  • Objectives The purpose of this study is to evaluate the fracture healing effect of extracts from Cnidium officinale and Angelica sinensis (CO/AS) in mice with femoral fracture. Methods C57BL/6 mice were randomly divided into normal, control (phospate-bufferd saline), positive control (tramadol), CO/AS extract 40 mg/kg and 80 mg/kg. By using Collier's method, all groups except normal group went through femoral fracture. Aspartate aminotransferase (AST), alanine transferase (ALT), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and creatinine were measured to evaluate the safety of CO/AS. Hematoxylin & eosin, Safranin O staining, x-ray, tensile and compressive force were conducted to assess the effect of CO/AS on fracture. Results The liver function test showed AST, ALT and LDH in CO/AS at 14th and 28th days were not significantly different compared with control group. The renal function test showed BUN in CO/AS at 14th days and BUN and creatinine in CO/AS at 28th days were significantly decreased compared with control group. The morphological & histological analysis and x-ray showed that CO/AS promoted cartilage and callus formation process compared with control group. The tensile and compressive forces test showed tensile in CO/AS 40 mg/kg and tensile & compressive forces in CO/AS 80 mg/kg were significantly increased compared with control group. Conclusions CO/AS extract showed the possibility that it promotes early fracture union and increases bone tensile and compressive strength, while does not have hepatotoxicity. In conclusion, CO/AS has a potential to promote healing of bone fracture and this study warranted the clinical usage of CO/AS at bone fracture.

  • Twenty-four Holstein dairy cows were used to evaluate the single and combined effects of different levels of crude protein (CP) and monensin treatment during early lactation on blood metabolites, milk yield and digestion of dairy cows. The experiment was designed as a completely randomized block with a $3{\times}2$ factorial arrangement of treatments. The factors were three concentrations of CP supplement (19.5, 21.4, and 23.4% of dry matter) and two levels of monensin (0 and 350 mg per cow per day). The experiment consisted of three phases and each phase was 3 wk in length. Monensin did not affect milk yield, lactose, solids-non-fat (SNF), blood glucose, triglyceride and DMI, but increased blood cholesterol, blood urea nitrogen (BUN), insulin and reduced blood ${\beta}$-hydroxybutyrate (BHBA), milk fat and protein percentage. Monensin premix significantly decreased rumen ammonia, but rumen pH and microbial protein synthesis were not affected by monensin treatment. Increasing dietary CP improved milk and protein production, but did not alter the other components of milk. Digestibility of NDF, ADF, CP were improved by increasing dietary CP. Increasing dietary CP from 19.5 to 21.4% had no significant effect on ruminal ammonia, but increasing CP to 23.4% significantly increased ruminal ammonia. There was a linear relationship between level of crude protein in the diet and volume of urine excretion. Microbial protein synthesis was affected by increasing CP level; in this way maximum protein synthesis was achieved at 23.4% CP.

  • White-skinned sweet potato (WSP, Ipomoea batatas L.)는 일본, 인도네시아 등에서 당뇨병과 그 치료에 민간에서 사용되고 있다. 본 실험에서는 WSP의 메탄올 추출물을 체중 1 kg 당 Dose 100, 200 mg을 투여하여 streptozotocin으로 유발된 당뇨쥐에서 손상된 신장 보호효과를 평가하였고 그 효능을 인슐린 분비촉진제인 glimepiride (45 mg/kg 체중)와 비교해 보았다. WSP 메탄올 추출물과 glimepiride를 2주 투여 한 후 혈당, 혈중 요소성 질소(BUN), 크레아티닌, 젖산 탈수소효소(LDH), 지질 과산화물(LPO) 함량, 그리고 항산화효소들인 superoxide dismutase (SOD), 카탈라아제(CAT), 글루타치온 과산화물 분해효소(GPx), 글루타치온 S-전이효소(GST) 등의 활성도를 측정하였다. BUN, 크레아티닌, LDH, 혈당, LPO 함량 등은 대조군에 비하여 그 값이 증가하였고, SOD, CAT, GPx, GST 값은 감소하였다. WSP 메탄올 추출물(200 mg/kg)을 투여한 후 측정한 값은 혈당, LPO, 신장병 표지인자인 BUN, 크레아티닌, LDH, 그리고 지질 과산화물 함량에서 의미있는 개선효과를 볼 수 있었고 항산화효소, 항산화물질의 증가도 나타났다. 따라서 WSP 메탄올 추출물은 당뇨쥐의 혈당을 낮추며 산화적 스트레스를 약화시키고 당뇨로 유발된 신장 손상을 보호해 주는 효과가 있다는 결과를 얻었다. 또한 민간에서 사용하고 있는 WSP가 실제로 당뇨 치료에 효과가 있음을 과학적 증거로 제공해 주었다고 판단된다.
