Clinical signs, serum chemical values and histological findings of hepatic tissue after partial and complete obstruction of common bile duct in Korean goats were investigated. Abnormal clinical signs were not observed in partial obstruction of common bile duct, but in complete obstruction clinical signs such as jaundice, urine color change, were observed. Serum total bilirubin, total cholesterol, aspartate aminotransferase, sorbitol dehydrogenase, gamma glutamyltranspeptidase, and total protein values increased on the 1-4th day and then gradually decreased to normal level in partial obstruction. However, they tend to increase persistently by the 24th day in complete obstruction of common bileduct. Histologic features of hepatic tissue in partial obstruction were not changed as compared with normal hepatic tissue. On the other hand, in complete obstruction of common bite duct there were moderate bile duct proliferation in a portal area, rupture of bile canaliculi, phagocytosis of bile pigment by Kupffer cells, periportal fibrosis, intrahepatic bile stasis and hepatic cell necrosis.

Liquid chromatography/mass spectrometry using isotope dilution method has been established as a primary method for the measurement of cortisol in human serum. Verification of this method was accomplished by the participation in Consultative Committee for Amount of Substance-Metrology in Chemistry (CCQM) pilot study. Two levels of cortisol certified reference materials were prepared and certified by the established method. They were used as sample materials for the proficiency testing. The expanded uncertainty in the measurement of cortisol in human serum was approximately 1.2% at 95% confidence level. The results of the proficiency testing showed a good precision among the participants, but some bias to the certified values. This means that commercial field laboratories should keep traceability chain to SI unit through available reference measurement procedures and/or available reference materials.

In Oriental Medicine, hyperlipidemia is considered as the phlegm stagnancy(痰飮) and blood stasis(瘀血). Typhae Pollen helps remove blood stasis and hemorrhage and it also has an effect of relieving pains caused by blood stasis. The purpose of this study is to investigate the curative effects of Typhae Pollen on diet-induced hyperlipidemia in rats. Thirty-two rats were divided into normal, control and treated group. Control and treated group were fed with 1.5% cholesterol diet during 4 weeks, and fed with normal diet during next 4 weeks. Treated group was also administrated with extract of Typhae Pollen during last 4 weeks. Blood samples were collected from each of animals at 4, 6 and 8weeks, and used for the blood chemical analysis. Animals were sacrificed at 8 weeks, and chemical analysis was performed on the collected liver samples. The serum total cholesterol(47.82±2.03㎎/㎗), LDL-cholesterol(11.09±1.27㎎/㎗), HDL-cholesterol (19.64±1.23㎎/㎗), triglyceride(85.09±3.48㎎/㎗) values of treated group were significantly decreased compared with the serum total cholesterol(73.73±5.34㎎/㎗), LDL-cholesterol(22.09±3.09㎎/㎗), HDL-cholesterol(25.18±1.45㎎/㎗l), triglyceride(124.27±6.72㎎/㎗) values of control group at 8weeks. The liver total cholesterol and triglyceride values of treated group show no statistically significant differency compared with those values of control group. On the basis of these results, it is confirmed that Typhae Pollen has the curative effects on the hyperlipidemia in rats induced by hyper-cholesterol diets.

This study was performed to clarify the induction possibility of anaphylactoid reactions by the administration with the heartworm extracts, and, if any, to elucidate different virulences in terms of the protein concentrdtions and sexes of Dirofilaria immitis. Twenty three clinically healthy D. immitis-free adult dogs were used in the present study. The experimental animals were divided into 5 groups. Group A (5 heads) was administered with an female heartworm extract containing 0.1 g/dl protein concentration. Group B (4 heads) was administered with an male heartworm extract containing 0.1g/dl protein concentration. Group C (5 heads) was administered with an female heartworm extract containing 0.2 g/dl protein concentration. Group D (4 heads) was administered with an male heartworm extract containing 0.2 g/dl protein concentration. Group E (5 heads) was administered with an female heartworm extract containing 0.4 g/dl protein concentration. The changes of clinical symptoms and vital signs (body temperature, heart rate and respiration rate) were examined before and 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours and 24 hours after injection with the extracts, respectively. In addition, the changes of hematological values (RBC, PCV and total leukocytes counts), serum chemical values (ALP and CK) were determined. It was considered that heartworm extract could induce anaphylactoid reaction and adult female heartworm extract was more affective than those of adult male heartworm extract in the changes of clinical symptoms, vital signs, hematological values and serum chemical values.

Objectives : In Oriental Medicine, hyperlipidemia is considered as phlegm retention (痰飮) and blood stasis (瘀血). Typhae pollen helps remove blood stasis and hemorrhage, and it also has an effect of relieving pain caused by blood stasis. The purpose of this study is to investigate the preventive effects of Typhae pollen on diet-induced hyperlipidemia in rats. Methods : Thirty-two male Sprague-Dawley rats were divided into normal, control and treated groups. The control and treated groups were fed with a 1.5% cholesterol diet over 4 weeks, and extract of Typhae pollen was administered to the treated group during the same period. Blood samples were collected from each animal at 0 and 4 weeks and used for the blood chemical analysis. Animals were sacrificed at 4 weeks and chemical analysis was performed on the collected liver samples. Results : The serum total cholesterol ($122.45{\pm}4.96mg/dL$), LDL-cholesterol ($54.27{\pm}4.95mg/dL$), and triglyceride ($122.00{\pm}7.33mg/dL$) values of the treated group were significantly lower compared with the serum total cholesterol ($147.91{\pm}7.22mg/dL$), LDL-cholesterol ($81.91{\pm}8.34mg/dL$), and triglyceride ($169.27{\pm}12.34mg/dL$) values of the control group. The liver total cholesterol (TEX>$230.18<{\pm}18.81mg/dL$) values of the treated group were significantly higher compared with the liver total cholesterol ($178.54{\pm}$10.11mg/dL) values of the control group. Conclusions : On the basis of these results, it is confirmed that Typhae pollen has preventive effects on diet-induced hyperlipidemia in rats.

This experiment was carried out to study the toxic effect of solublized methylcellulose (MC). Sprague-Dawley rats were dosed with 1%(w/v) MC in 0.9% saline by gavage at a dose of 10ml/kg b.w/day or by intravenous injection at a dose of 5ml/kg b.w/day for 28 days. Clinical signs were observed once a day. Body weights, water and food consumptions were measured and urinalysis was performed several times during the experiment. Rats were sacrificed on days 3, 7, 15 and 28 for hematology, blood chemistry, organ weights and histopathology. The relative weight of the spleen and foamy cells of the spleen were increased in the gavage group. Body weight gain, food consumptions, the values of RBC, Hb, MCH, Hct, serum proteins, glucose, bilirubin, AST, and ALP were decreased in I.V. treatment group. On the other hand, water consumptions, the values of serum cholesterol, creatinine, and BUN were increased. Microscopic findings were granulomas, distended sinusoids, and hypertrophy of Kupffer cells with vacuoles in the liver. Spleen exhibited granuloma, increased extramedullary hematopoiesis, and congestion. Kidney exhibited foamy cells in the glomeruli, distension of the tubules. The findings appeared more severe when the treatment was extended. In conclusion, MC solution is not a safe vehicle for intravenous administration because of the toxic effects on the liver, kidney and spleen. In addition, a long-term and large dosage of oral administration of MC appears to be unsafe also and needs to be investigated further.
