Investigations for hematologic and biochemical values and the differential count of WBC for Korean indigenous cattle (KIC)is rarely performed. Therefore, when the index of complete blood counts (CBC) and biochemical analysis of KIC was requested, it had many difficulties to make the results for blood condition since the standard hematologic and biochemical values of KIC are lacking. In the present study, we have investigated the hematologic and biochemical values and the differential count of WBC for blood of total 252 KIC and 17 striped cattle (SC) as a control. As a result, the mean values of RBC and platelet of KIC were significantly decreased by age (P<0.05). The mean values of RBC, HCT, MCV and MCHC between KIC and SC of the same age (2 - 3 years) showed the statistical significance (P<0.05). Also, in the WBC of KIC, the mean values were decreased according to the age from $12.8{\times}10^3/{\mu}l$ under 1 year to $8.5{\times}10^3/{\mu}l$ over 5 years. In the differential count of WBC of KIC, it showed generally the rates of 45% lymphocyte and 35% segmented neutrophil. In the biochemical analysis, the mean values of BUN and globulin were significantly increased according to the age (P<0.05). Additionally, in comparative analysis between pregnant and non-pregnant group of KIC, the mean values of Hg and HCT in pregnant group were significantly decreased (P<0.05). In conclusion, data obtained from this study may be valuable as a standard for interpretation of the results in hematologic and biochemical analysis of KIC.

Changes of plasma DNA contents and serum biochemical values were measured in rats administered with $HgCl_2$ to investigate the in vivo cytotoxic effects of mercury and examine the usefulness of these changes as indicators of mercury exposure and diagnosis of mercury poisoning. Rats were given once intraperitonealy $HgCl_2$(0.13. 0.32. 0.8 and 2 mg/kg b.w) and the changes of plasma DNA contents and serum biochemical values were measured at the time of 2, 4, 8, 24, 48 and 72 hours after the administration of $HgCl_2$. Plasma DNA contents began to increase from 2 hours after the administration of $HgCl_2$ in all the treatment groups significantly compared to control with dose-dependent pattern. The levels of plasma DNA reached to peak at 48 hours as 2.77, 7.60, 15.46 and 16.51 times higher than control in each treatment group of 0.13, 0.32, 0.8 and 2 mg/kgb.w, respectively and remained to be higher until 72 hours after the administration. The values of creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, blood urea nitrogen and glucose of serum were increased, however the values of alkaline phosphatase, total protein and triglyceride were decreased. These changes of increase and decrease showed dose-dependent pattern but the starting time, maintenance and magnitude of change were various and characteristic according to serum biochemical indices. Among the changes of serum biochemical values, those of aspartate aminotransferase, lactate dehydrogenase and blood urea nitrogen were apparently and significantly increased compared to control from 2 to 72 hours by the administration of 2 mg/kg $HgCl_2$. This study demonstrates that plasma DNA and serum biochemical values such as aspartate aminotransferase, lactate dehydrogenase, blood urea nitrogen and etc. are valuable as biomarkers for mercury exposure assessment and diagnosis of mercury poisoning.

Serum biochemical values were measured in blood samples collected from 8 fasted stags from both jugular and femoral veins at 18-day intervals during antler growth. Samples were analyzed for blood substrate, enzyme activity values, minerals and electrolyte. There were no significant differences in total protein, albumin, urea, creatinine, triglyceride, glucose or cholesterol concentration between veins or sampling dates. However, total-bilirubin concentration in the jugular vein on the casting date was three times higher than on the other sampling dates (p<0.05). There were no significant differences in alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase with progressing antler growth. The highest level of alkaline phosphatase concentration was on day 55 after casting. There were no significant differences in inorganic phosphorus, sodium and chloride concentration between jugular and femoral samples. Calcium concentration was significantly higher in the femoral vein on the cutting date (55 day) than in the jugular vein (p<0.05). There were few changes in serum biochemical values. However, some electrolytes and minerals had differences during antler growth. It is suggested that despite such a big event as antler growth, blood biochemical values are not variable if feeding conditions are consistently maintained as was the case in this study.

To diagnose acute myocardial infarction (MI), many cardiac markers have been used in hematologic and biochemical analysis, and many studies have been published for hematologic and biochemical analysis associated with human acute MI. However, after occurrence of acute MI, the serial investigation for values in hematologic and biochemical analysis including chronic MI has rarely been performed. To observe the change of the serial values in hematologic and biochemical analysis, we induced artificial MI. The left main descending artery (LMDA) of the left coronary artery was ligated during the progression (day 1, 3, 5, 7, 14 and 30) of MI. Total 66 Sprague-Dawley rats were divided into the sham group (n=24, thoracotomy without LMDA ligation) and the experimental (MI) group (n=42, with LMDA ligation). And all individual in each group was sacrified at day 1, 3, 5, 7, 14 and 30 for the hematologic and biochemical analysis. In comparison of hematologic analysis between the sham and MI groups, the mean values of red blood cell (RBCs), hemoglobin and hematocrit (HCT) showed a steady increase. In biochemical analysis, the mean values of glucose, cholesterol, total creatine kinase (CK) and isoenzyme MB, and lactate dehydrogenase (LDH) were increased in all MI groups compared with the sham groups. The results of this study suggest that early hematologic and biochemical mean values occurred after acute MI are similar to those of human acute MI. In conclusion, we could observe the alterations and serial values in hematologic and biochemical analysis to the extent of chronic status after acute MI.

Changes of plasma DNA contents and serum biochemical values were measured in rats administered with lead acetate to investigate the in vivo cytotoxic effects of lead and examine the usefulness of these in vivo cytotoxicity changes as indicators of lead exposure and diagnosis of lead poisoning. Rats were given once intraperitonealy with lead acetate (1.6, 8, 40 and 200 mg/kg b.w) and the changes of plasma DNA contents and serum biochemical values were measured at the time of 2, 4, 8, 24, 48 and 72 hours after the administration of lead acetate. Plasma DNA contents began to increase at 2 hours after the administration of lead acetate in the treatment groups of 8, 40 and 200 mg/kg b.w dose-dependently and significantly compared with control group. These DNA increases of each dosage group were continued until 24, 48 and 72 hours and the maximum levels of DNA (4.02, 10.67 and 14.10 times of control) were arrived at 8, 8 and 4 hours after the each treatment, respectively. Among 10 serum biochemical indicators, the activities of creatine kinase were increased to maximum level (6.55 times of control) at 2 hours after the administration and remained to be significantly higher than that of control by 8 hours in the treatment group of 200 mg, however, after 48 hours, the levels in the treatment groups of 40 mg above were lower than that of control. The values of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase were higher than that of control from 2 to 24 hours in the treatment group of 200 mg. Maximum levels of these enzymes were 3.34, 3.00 and 3.19 times of control, respectively. Both of alkaline phosphatase and triglyceride values in the treatment groups were decreased compared with control. In the case of alka-line phosphatse, the values were significanly decreased from 24 hours and more severely decreased until 72 hours in the treatment groups of 40 mg above (p<0.01). The minimum value was 0.36 times of control in the 200 mg group. The values of triglyceride were significantly decreased in the tratment groups of 40 mg above (p<0.01), but the values were not different significantly among the treatment groups. This study demonstrates that plasma DNA content and serum biochemical values such as aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, alkaline phosphatase and triglyceride are valuable as biomarkers for exposure assessment and diagnosis of lead poisoning.

나이가 들어가면서 나타나는 여러 가지 변화를 임상적으로 검사하고 측정하므로써 건강상태를 예측하는 것은 노화를 지연시키고 건강한 삶을 유지하는데 상당히 유용하고 기초적인지표가 될 것이다. 점차 증가일로에 있는 노인성 질환의 여러 문제점을 해결하기 위해 노령인구 집단을 정상군과 치매군으로 구분하여 13종의 임상화학 검사를 시행한 결과, 두 집단 사이에서, 임상 생화학적 검사의 양상이 다를 것이라는 예측대로의 결과를 얻을 수 있었다. 즉, serum albumin, APase, glucose, GOT, LDH 등의 수치는 정상군과 치매군 사이에서 현저한 차이를 보이는 반면, bilirubin, BUN, cholesterol, creatinine, total protein 등의 검사 수치에서는 별다른 차이를 볼 수 없었으며 , 그밖에 calcium, GPT, Pi 검사 등의 결과에서도 두 집단 사이에서 차이를 보였다. 이것은 치매가 체내에서 많은 생화학적 변화를 일으킴을 시사하고, 치매 발병에 여러 가지 환경 요인이 영향을 미치게 될 것이라는 결론을 유도할 수 있게 한다.

Purpose: To determine the utility of secondary circulating prostate cells for predicting early biochemical failure after radical prostatectomy for prostate cancer and compare the results with the Walz nomagram. Materials and Methods: A single centre, prospective study of men with prostate cancer treated with radical prostatectomy between 2004 and 2014 was conducted, with registration of clinical-pathological details, total serum PSA pre-surgery, Gleason score, extracapsular extension, positive surgical margins, infiltration of lymph nodes, seminal vesicles and pathological stage. Secondary circulating prostate cells were obtained using differential gel centrifugation and assessed using standard immunocytochemistry with anti-PSA. Biochemical failure was defined as a PSA >0.2ng/ml, predictive values werecalculated using the Walz nomagram and CPC detection. Results: A total of 326 men participated, with a median follow up of 5 years; 64 had biochemical failure within two years. Extracapsular extension, positive surgical margins, pathological stage, Gleason score ${\geq}8$, infiltration of seminal vesicles and lymph nodes were all associated with higher risk of biochemical failure. The discriminative value for the nomogram and circulating prostate cells was high (AUC >0.80), predictive values were higher for circulating prostate cell detection, with a negative predictive value of 99%, sensitivity of 96% and specificity of 75%. Conclusions: The nomagram had good predictive power to identify men with a high risk of biochemical failure within two years. The presence of circulating prostate cells had the same predictive power, with a higher sensitivity and negative predictive value. The presence of secondary circulating prostate cells identifies a group of men with a high risk of early biochemical failure. Those negative for secondary CPCs have a very low risk of early biochemical failure.

We executed this experiment to observe side effects of warfarin, the anticoagulant that is used for preventing thrombus in cardiovascular surgery for calves. The 6 calves(70-130 kg) were used in this experiment regardless of sexes. We administered warfarin at 0.07 mg/kg daily for 25 days. Blood was collected before warfarin administration, every five days for 30 days. PCV, RBC, WBC, fibrinogen, total protein and platelet as blood test, prothrombin time (PT) as blood coagulation test, and AST, SDH, total bilirubin, BUN and creatinine as serum biochemical tests were measured. As the result of the experiment, PT has been gradually increased after warfarin administration. It has been gradually increased and remains within the therapeutic range from the third day to the 28th day. PCV and RBC were decreased significantly from the value before the administration (p < 0.05). In the serum biochemical test, SDH shows significant increase comparing the value before the administration (p < 0.05). AST and total bilirubin were increased gradually from the value before the administration. Considering the result of the experiment, to give wafarin to prevent thrombus in cardiovascular surgery, we can get anticoagulation effect with minimal administration(0.07 mg/kg, PO) from the third day of the administration. However because of the decreased PCV and RBC, it may cause anemia. It may cause damage to liver based on the result of serum biochemical test.
