  • This study was conducted to investigate the hematological changes of the dogs when administrated excessive amount of the Artemisia capillaris extract for a short period. In this experiment, clinically healthy dogs(n = 20, average weight = 7.68 kg) were divided into 2 groups : Artemisia capillaris rude juice extract group(CR) and concentrated extract group(CE). They were inserted stomach tube and administrated the extracts (5 ml/kg) for 8 days. The followings are the results of this experiment.: 1). The number of red blood cell(RBC) was significantly (p<0.05) decreased in CE group on day 4, 5, 6, whereas CJE group showed significantly (p<0.05) difference on day 5. 2). The packed cell volume(PCV) and hemoglobin concentration were significantly (p<0.05) decreased in both groups during experimental periods. 3). The met hemoglobin was significantly (p < 0.05) increased from 12 hrs after administration to day 8 in CJE group wheres, it was significantly (p<0.05) increased on day 6,7 in CE group.

  • Cytogenetic and hematological analysis was performed in peripheral blood of cattle in the vicinity of Uljin nuclear power station and control area. The frequency of micronuclei(MN) in peripheral blood lymphocytes from cattle was used as a biomarker of radiobiological effects resulting from exposure to environmental radiation. An estimated dose of radiation was calculated by a best fitting linear-quadratic model based on the radiation-induced MN formation from the bovine lymphocytes exposed in vitro to radiation over the range from 0 Gy to 4 Gy. MN ratio in lymphocytes of cattle from Uljin nuclear power station and control area were 8.90/1,000 and 9.60/1,000, respectively. There were no significant differences in MN frequencies and hematological values in cattle between Uljin and control area.

  • The pharmacological effects of hydrocooked(110oC, 5 hours) extracts of Bastard halibut have been investigated. All of the hydrocooked extracts showed the measurable contractile effect on the isolated rat duodenum and decreased the normal blood pressure in anesthetized rat. The hydrocooked extracts also exhibited a dose dependent relaxation on the isolated rat aorta precontracted with phenylephrine. Only RM 60 fraction of these extracts had the cytotoxic effect against MCF7 cell(human breast adenocarcinoma cell line), but the other fractions showed neither antibacterial activity nor antitumor activity. Although fish extracts fed group of rat maintained their original body weight, there were no notable changes in the hematological parameters, except that the levels of high density lipoprotein was significantly increased. These results suggest that the hydrocooked extracts of bastard halibut may contain a variety of bioactive materials.

  • Mercury, one of the most diffused and hazardous organ-specific environmental contaminants, exists in a wide variety of physical and chemical states. Although the reports indicate that the mercury induces a deleterious damage, little has been known from the investigations of its effects in living organisms. The purpose of this study is to evaluate the effects of mercury chloride and ionizing radiation. Prepubertal male F344 rats were administered mercury chloride in drinking water throughout the experimental period. Two weeks after whole body irradiation, organs were collected to analyze the induced injury. Serum levels of GOT, GPT, ALP, and LDH were checked in the experimental groups and the hematological analysis was accomplished in plasma. In conclusion, the target organ of mercury chloride seems to be urinary organs and the pattern of damage induced by mercury differs from that by irradiation.

  • This study was conducted to observe the hematological effect of the small dogs when administrated excessive amount of the Korean native chinese chive(Allium tuberosum Rottler) extracts for a short period. In this experiment, clinically healthy dogs(n = 10, average weight = 4.17 kg) were used. They were inserted stomach tube and administrated the extracts(5ml/kg) for 7 days. The followings are the result of this experiment. The red blood cell counts, hemoglobin concentration and mean corpuscular hemoglobin concentration were significantly decreased. (P<0.05) The packed cell volume was slightly decreased. The mean corpuscular volume and methemoglobin concentration were significantly increased.(P<0.05) The white blood cell counts and reduced glutathione were slightly increased. Consequently, We determined that administrated excessive amount of the Korean native chinese chive extracts induced hemolytic anemia.

  • This case report describes the hematological and radiological examination of urinary bladder rupture and complete urethral obstruction. associated with urolithiasis in Hanwoo. Hyponatremia, hypochloremia, azotemia, and hyperglycemia were observed in both urethral obstruction and urinary bladder rupture. However, cattle with urethral obstruction showed hyperkalemia and mild hyperglycemia, whereas cattle with bladder rupture showed marked hyperglycemia and normal potassium levels. In ultrasonography, the urethral obstruction showed a dilated bladder with a thick bladder wall. In contrast to previous literature, in this study, severe electrolyte changes such as severe hyponatremia, hypochloremia, and hyperkalemia occurred in a case of complete urethral obstruction.

  • Among the therapeutic strategies in cancer immunotherapy-such as immune-modulating antibodies, cancer vaccines, or adoptive T cell transfer-T cells have been an attractive target due to their cytotoxicity toward tumor cells and the tumor antigen-specific binding of their receptors. Leveraging the unique properties of T cells, chimeric antigen receptor-T cells and T cell receptor (TCR)-T cells were developed through genetic modification of their receptors, enhancing the specificity and effectiveness of T cell therapy. Adoptive cell transfer of chimeric antigen receptor-T cells has been successful for the treatment of hematological malignancies. To expand T cell therapy to solid tumors, T cells are modified to express defined TCR targeting tumor associated antigen, which is called TCR-T therapy. This review discusses anti-tumor T cell therapies, with a focus on engineered TCR-T cell therapy. We outline the characteristics of TCR-T cell therapy and its clinical application to non-hematological malignancies.

  • Ninety advanced Catla catla fingerlings (av. wt. 16 g) were randomly distributed in six treatment groups with three replicates each for an experimental period of 60 days to study the effect of dietary lipid source on growth, enzyme activities and immuno-hematological parameters. Six isoprotein (40.0-41.9%) and isocaloric (4,260 kcal $kg^{-1}$) semi-purified diets were prepared with varying levels of soybean oil (SBO) and cod liver oil (CLO) within a total of 8% lipid viz., $D_1$ (Control), $D_2$ (8% SBO), $D_3$ (6% SBO and 2% CLO), $D_4$ (4% SBO and 4% CLO), $D_5$ (2% SBO and 6% CLO) and $D_6$ (8% CLO). Highest SGR was noted in $D_5$ (0.73${\pm}$0.03) group, which was similar with $D_3$ (0.71${\pm}$0.02) and $D_4$ (0.69${\pm}$0.01) groups. Activity of intestinal lipase, hepatic glucose-6-phosphate dehydrogenase (G6PDH) and aspartate amino transferase (AST) of the lipid treatment groups were significantly higher (p<0.05) than the control group. The respiratory burst activity of the phagocytes (Nitroblue tetrazolium (NBT)) was highest in $D_2$ (1.95${\pm}$0.21) followed by $D_3$ (1.19${\pm}$0.15) group, which were significantly (p<0.05) higher than the other groups. Globulin level was significantly higher in $D_3$ (1.29${\pm}$0.08) than in the other groups expect $D_4$. Hemoglobin content and total erythrocyte count did not show any significant difference. From this study, it is concluded that a diet containing 6% soybean oil and 2% cod liver oil ($D_3$) yields higher growth and immune response in Catla catla fingerlings and would be cost effective.
