This study was conducted to investigate the effects of mugwort extracts on the blood ethanol concentration and liver function in rats. Sprague-Dawley rats were used, the rats administered with 25% ethanol (5g/kg$.$B.W.) were devided into three groups (CON-E ; 25% ethanol administered to the CON-E) according to the administered ethanol concentration and the levels of administered mugwonts. Mugwont roots extracts were administered via the caudal vein. Ethanol concentration was measured at the time of 0, 1, 2 and 3hr by gas chromatography. GOT(Glutamic Oxaloacetic Transaminase) and GPT(Glutamic Pyruvic Transaminase) were measured at the time of 0 and 5hr. Components of each extracts were analyzed by using high performance liquid chromatography. Cell number, GOT and GPT were investigated by using rat hepatocyte culture. Megwort extracts were added at the levels of 1% or 2%. Hepatocyte culture were into five groups according to the addition levels. The results were summarized as follows ; 1. Catechin contents of 8∼10mg/100g and the contents of (-)-epigallocatechin was high in the water extracts. 2. Ethanol degradation efficiency declines in the following order : MDW-E＞MOH-E＞CON-E. 3. The numbers of rat hepatocytes declines in the following order : 2% MDW-L＞1%MDW-L＞1%MOH-L＞CON-L＞2%MOH-L. These results suggest that crude catechin of mugwort extracts may play important roles to degrade ethanol and recover liver function in rats.

혈액의 점도가 높아질수록 혈액은 더 끈적하고 흐름이 어려워지므로 혈전의 발생 가능성이 높아져 허혈성 뇌경색의 발생 확률이 증가한다. 혈액 점도 측정은 최근 순환기계 질환의 예방을 위하여 그 중요성이 강조되고 있으며 혈액의 점도를 쉽고 정확하게 측정할 수 있는 점도계의 필요성이 대두되고 있다. 본 연구에서는 평행판 점도계 ARS-Medi에 의한 점도표준액과 인공혈액의 측정값들을 국제적으로 정확성과 신뢰성을 인정받는 TA instrument의 Ares-G2로 측정한 값들과 비교하였다.. 뉴턴성 용액인 N44 표준용액의 점도는 모든 전단율에서 두 기기 간에 거의 완벽하게 일치하였다, 비뉴턴성 용액인 인공혈액의 경우 가장 낮은 전단율인 1 rad/s 에서는 약 10%의 차이를 보였으나, 임상적으로 유의한 전단율인 10 rad/s 이상에서는 두 기기간의 측정값이 오차범위 내에서 모두 일치하였다. 우리는 새로 개발한 혈액 전용 평행판형 점도계 ARS-Medi가 1회용 평행판을 사용하므로 혈액 점도 측정의 편의성과 위생성이 향상되어 임상에 매우 유용할 것으로 기대한다.

Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.

Reciprocal exchanges of DNA in sister chromatids (SCEs) are induced by various carcinogens and mutagens, although the quantitative relationship between the number of mutations and SCEs induced varies among chemicals. Nevertheless, the analysis of SCEs production by various agents often proposed as a sensitive and quantitative assay for mutagenicity and cytotoxicity. Mercury, even if which has no evidences for mutagenicity and carcinogenicity, is reported to exert some cytotoxic effects, such as chromosomal aberrations or bad influences to ovulation and reproduction in experimental animals, etc.. In this study, tests for sister chromatid exchanges have been carried out on normal human lymphocytes in whole blood culture to add mercury chloride ($HgCl_2$) or methylmercury chloride ($CH_3\;HgCl$) for 72 hr. The results indicate the dose-dependent relationship between the frequencies of SCEs and the concentrations of $HgCl_2,\;CH_{3}HgCl$ and 5-bromo-2'-deoxyuridine (BrdU). Lymphocyte proliferation has depressed in the higher concentration of mercury.

Open heart surgery patients have additional risks arising from the special nature of the operative procedure. And postoperative infections in patients with extracorporeal circulation are associated with high incidence of serious sequelae. To investigate the incidence and organisms of contamination, and the relation between the duration of extracorporeal circulation and contamination, following study was done. Eighty-four of the open heart surgery patients were examined with cultures from the blood and priming solution before and after bypass. 1. Cultures before bypass were sterile, but 2 cases of cultures from the blood and priming solution after bypass were positive, and culture positive group was 5% of all patients. 2. The organisms were Gram-negative, aerobic coliform bacilli; 3. The culture positive group had significantly longer bypass time.

The studies were carried on to set up a short term blood culture method which is essential for doing bovine cytogenetic investigation and to reduce the amount of the various reagents wish better results obtained with modified methods were compared with the results of Basrur's and Halnan's methods, and the following results were obtained. 1. The modified method, with lesser amount of reagents than other methods, produced better results and showed cleaner spreads. 2. Better spreads were obtained, in the modified method, by modifying the hypotonic treatment. 3. Reduction of the PHA to 1/10 comparison with the other methods showed no harmful effects.

Background: The aim of the present study was to determine the effects of feeding trace mineralsfortified mixed microbial culture (TMC) on ruminal fermentation, nutrient digestibility, blood electrolyte status, nitrogen balance, and trace mineral balance in sheep. Methods: Mixed microbes [0.6 % (v/w) of Enterobacter sp., Bacillus sp., Lactobacillus sp., and Saccharomyces sp.] were cultured with 99 % feedstuffs and 0.4 % trace minerals including zinc and copper for ensiling. Six sheep (a mean body weight of $46.5{\pm}1.2kg$) were fed two diets: a control diet (concentrate mix and rye straw) and an experimental diet (a control diet + 3.1 % TMC). Results: TMC feeding did not induce negative effects on ruminal fermentation, nutrient digestibility, blood electrolytes, and nitrogen balance in sheep. Feeding with TMC increased the intake of trace minerals (p < 0.05) and did not affect absorption of trace minerals in the whole digestive tract. Feeding with TMC increased fecal excretion and absorbable intake, and retention of zinc and copper (p < 0.05) by 71 % and 77 %, respectively. Conclusion: Feeding with TMC resulted in higher zinc and copper bioavailability and retention without any adverse effects on sheep performance.

A 12-year-old intact female Pomeranian dog was presented with vulvar discharge, lethargy, polyuria, and polydipsia. A complete blood count revealed leukocytosis and anemia. The serum biochemical analyses showed elevated serum alkaline phosphatase activity and blood urea nitrogen. Survey abdominal radiography revealed an enlarged left kidney. Abdominal ultrasonography identified multiple rounded hypoechoic subcapsular lesions in the left kidney. The bilateral uterine horn was enlarged, and contained echogenic fluid. Percutaneous ultrasonographic-guided aspiration of the renal subcapsular lesions was performed on the left kidney. Cytological examination revealed bacterial cocci, degenerated neutrophils, and suppurative inflammation. Bacterial culture produced growth of Escherchia coli. Left nephrectomy and ovariohysterectomy were performed. Dilated uterine fluid was also evaluated for bacterial culture, and showed growth of E. coli. Urine was examined by bacterial culture, and showed negative results. The treatment consisted of antibiotic therapy according to the antibiotic sensitivity test. Based on these findings, the diagnosis was renal subcapsular abscess associated with pyometra. This study suggests that pyometra should be considered as the cause of renal abscess.

For examination of antibiotic therapeutic efficacy in canine brucellosis, this examination was carried out two female bitches infected with Brucella canis in Gyeongbuk province, and used combicillin, baytril and doxycycline in susceptible antibiotics at B canis. During 18 month after the termination of antibiotic therapy, blood sample of the two bitches were examined for B canis antibody and antigen. The antibody of one bitch was disappeared at 5 month after antibiotic therapy and the other was continued at 18 month, but two bitches were not detected antigen by blood culture and PCR. Examination of blood chemical value (AST, ALT, urea, creatinine) of two bitches was increased in AST value during antibiotic therapy.
