The effects of continuous administration of tiletamine-zolazepam(T-Z) on the blood, liver and kidney of dogs were evaluated. The drug was repeatedly administered into ten mongrel dogs intramuscularly at dose of 10mg/kg for every seven days. Hematology(PCV, WBC, RBC, TP, Fibrinogen) and serum chemistry(ALT, AST, BUN, Creatinine) were monitored for 14 days postinjection. No significant changes in PCV values, total RBC counts and plasma total protein values was found. Total WBC counts and fibrinogen values were significantly increased from 2 days to 7 days postinjection. There was no significant change in ALT, AST, BUN and creatinine levels. All animals were euthanized and necropsied at 14 days postinjection. No gross lesion and pathologic lesion was found on liver and kidney in necropsy finding.

The effects of aloe on the MDA(malondialdehyde) and the blood biochemical components of heavy metal poisoning in SD rat were examined and the following results were obtained. In rat liver homogenate intoxicated with $CdCl_2$, lipidperoxide was increased each 2.37times(24h), 3.31times(72h) but lipidperoxide In aloe administration groups was lower each 47% , 64% than in heavy metal group. In rat kidney homo- genate intoxicated with $CdCl_2$, lipidperoxide was increased 1.85times(24h), 1.33times(72h) but lipidperoxide in groups was almost the same as that of normal group. Lipidperoxide of kidney homogenate was slightly decreased as time passed. Also heavy metal poisoning rats showed high levels(1.38-2.50times) of serum AST, ALT and BUN. However. the administration of aloe significantly inhibited the reduction of them. These results suggest that Cd-induced hepatic and renal injury, via increase llpidpero)Ode and release of AST, ALT and BUN. Aloe may be used to inhibit or prevent the hepatic and renal toxicity which results from the heavy metal.

The effects of continuous administration of propofol on the blood, liver and kidney of dogs were evaluated. Propofol(5mg/kg) was repeatedly administered to 8 mongrel dogs intravenously for consecutive seven days. Time to recovery, body temperature, heart rate, and respiratory rate were measured and recorded during experimental period. Hematology (WBC, RBC, PCV) and serum chemistry (AST, ALT, BUN, Creatinine) were also monitored for eight days. Time to standing significantly decreased on day 4 and 6 compared with that on day 1. Body temperature 5 minutes after injection on day 5 and 6, and respiratory rate before injection on day 2, 3, 5 and 6 were significantly increased, respectively. No significant changes were observed in total WBC counts, total RBC counts and PCV values. The AST and AIT values were decreased on day 2 compared with those on day 1, but were within clinically normal range. There were no significant changes in BUN and Creatinine levels. This study suggests that consecutive day propofol anesthesia in dogs can be used for the purpose of the treatment and restraint.

Over-consumption of alcohol leads to many side-effects such as malnutrition, liver disease, and neuronal disorders and many investigators have tried to identify methods for preventing the side-effects of drinking. This study was carried out to investigate the effect of the beverage contained green tea catechins (GTC) on the alcohol administered rats. We observed that blood alcohol concentration level decreased significantly in plasma. GTC (200 mg/kg) also reduced the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) level of the intoxicated rats. These results suggest that GTC may be useful for the prevention and therapy of hepatotoxic pathogenesis.

Background: An automated immunohematology analyzer, DAYMATE M (DAY Medical, Switzerland), has been recently developed. The potential of this analyzer to improve test results has been evaluated. Methods: A total of 300 blood samples from Seoul St. Mary's hospital and Incheon St. Mary's hospital were tested for ABO and RhD typing. In addition, 336 antibody screening test (AST) samples and 82 patients treated with hematopoietic stem cell transplantation (HSCT) were included. AST results by DAYMATE M were compared with those obtained by a manual method using DS-Screening II (Bio-Rad Laboratories, Switzerland) and red blood cells from Selectogen (Ortho-Clinical diagnostics Inc., USA). Results: Of the 300 patients enrolled, 87, 73, 79, and 61 had type A, B, O, and AB blood, respectively. The concordance rate was 99.9% for cell typing and 97.0% for serum typing. One discordant case was classified as type B instead of AB, and six discordant serum-typing cases were type A, but classified as type AB. Among the 336 AST samples, the concordance rate was 93.2%. From 136 positive cases, six were discordant. Within the 82 HSCT-treated patients, the concordance rate for ABO blood typing was 92.2%. Among the six discordant cases, DAYMATE M typed four cases as donor type where the standard method typed them as the recipient blood type. Conclusions: The DAYMATE M automated immunohematology analyzer performs reliably for ABO and RhD typing, as well as for ASTs and on samples from patients treated with HSCT.

Blood-sensitive reagents may exhibit false positives or negatives under the influence of substances other than blood. Since these reactions lead to the misinterpretation of blood evidence, it is essential to investigate the possibility of false-positive and -negative reactions of blood-sensitive reagents. Acidic hydrogen peroxide (AHP) is a recently discovered blood-sensitive reagent, and it is not yet known whether it causes false-positive or -negative reactions. To confirm this, 20 µL of blood was placed on metal surfaces, plastic surfaces, paper surfaces, paint surfaces, foods, vegetable oils, detergents, and petroleum hydrocarbons, and then AHP was applied. The blood was observed through an orange filter under a 505-nm light source, and no false-positive or false-negative reactions were observed with any of the substances/materials. However, it was confirmed that polyethylene terephthalate surfaces, polyvinylchloride surfaces, some paint surfaces, and foods exhibit their own photoluminescence under the conditions of blood observation, which interferes with blood observation.

Starvation, diabetes, alcoholism and hypothermia cause ketoacidosis in the human body; therefore, the cause of death can be determined by analyzing ketone bodies in the blood of the deceased. In the case of decomposition of the cadaver, however, since collecting intact blood is impossible, ketone body analysis is performed using the spleen. However, the index for diagnosing ketoacidosis is based on blood concentration, and its correlation with ketone bodies present in the spleen remains unknown. In particular, since decomposition proceeds rapidly during summer, when temperature and humidity are high, understanding the correlation between ketone bodies in the blood and spleen is important to estimate the state at the time of death from a decaying body. Therefore, in the present study, the correlation between ketone bodies in the blood and spleen of the deceased was explored. Ketone bodies (beta-hydroxybutyric acid [BHB] and acetone) in the blood and spleen were analyzed and compared from autopsies (>100 mg·L^-1 BHB, blood basis) conducted at the Daejeon Forensic Research Institute from June to December 2021. Moreover, the concentration of ketone bodies in the spleen juice and tissues was compared assuming the scenario of extreme decomposition. Ketone retention concentration in the blood and spleen was positively correlated, and the ratio of BHB concentration in the spleen to BHB concentration in the blood ranged from 0.52 to 1.08 (mean = 0.85 ± 0.12), although the ratio may vary depending on the degree of decomposition of the corpse.

The present study was undertaken to compare the variation on serum biochemical values by storage in the rats. Sera were prepared from 30 Sprague-Dawley rats of each sex. 5 aliquots from each serum were placed in a -80$^{\circ}C$ freezer with the exception of I aliquots which was analyzed immediately. The analysis was performed on the following months; 1, 2, 3, 6, and 12 months after freezing. The parameters measured) were aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN) creatinine(CRE), glucose(GLU), total cholesterol(TCHO), triglyceride (TG), total protein(TP), albumin(ALB), total bilirubin(TBIL), calcium(Ca$\^$＋＋/), inorganic phosphorus(IP), creatine kinase (CK), phospholipid(PL), albumin-globulin ratio(A/G), sodium(Na$\^$＋/), potassium(K$\^$＋/), and chloride(Cl$\^$－/) The statistical analysis with Repeated Measures ANOVA, did not show statistical significance in the parameters of AST, ALT, BUN, TG, CK, A/G, Na$\^$＋/ of 1 month freezed sera, in those of AST, TG, CK, K$\^$＋/) of 2 month freezed sera, in those of AST, ALT, BUN, CRE, TCHO, TP, TBIL, CK, PL, Na$\^$＋/), K$\^$＋/), Ct on month fteezed sera, in those of Cl$\^$－/ of 6 month fteezed sera, and in those of ALT, TG, ALB of 12 month freezed sera in male SD rats. On the other hand, it did not show statistical significance in the parameters of AST, ALT, ALP, BUN, GLU, TCHO, TG, TBIL, CK, PL, A/G, Na$\^$＋/ of 1 month freezed sera, in those of AST, TCHO of 2 month freezed sera, in those of AST, BUN, CRE, TCHO, TP, TBIL, CK, PL of 3 month freezed sera, in those of TCHO, IP, PL of 6 month freezed sera, and in those of ALB of 12 month freezed sera in female SD rats. On the basis of the results, although there are some statistical variations in the biochemical values of the sera, it is suggested that if sera are analysed at the same time before 12 months storage in a －80 $^{\circ}C$ freezer, the storing time does not affect the biochemical evaluation of the sera in SD rats.

This study was investigated the biochemical mechanism on reducing blood lipids in second-generation rats fed diet with different omega 6 to omega 3 fatty acid ratio. The experiment treatment groups were classified into the groups with the omega 6 to omega 3 ratios of 0 (control group), 1:1, 8:1, and 19:1, respectively. The levels of the blood triglyceride, total cholesterol, low density lipoprotein-cholesterol (LDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and glucose were lowest in the group with the omega 6 to omega 3 ration of 1:1. The levels of high density lipoprotein-cholesterol and phospholipid were highest in the group with the omega 6 to omega 3 ration of 1:1. The HMG-CoA reductase activity was suppressed in the groups with the omega 6 to omega 3 ratio of 1:1 and 8:1 compared with that in the control group, but the excretion of sterol through feces was promoted. The blood omega 6 to omega 3 ratio decreased in a concentration-dependent manner depending on the increase in the omega 6 to omega 3 ratio within the ingested diet. The results of this study demonstrated a new finding that when the parent generation and second-generation rats ingested the diet with the omega 6 to omega 3 ratio of below 8:1, harmful lipids in the blood were reduced, the liver functions were maintained, and the growth was promoted due to the nutrient metabolism activation mechanism.
