  • A recombinant human erythropoietin (rHu-EPO), was administered intravenously to beagle dogs at doses of 100, 500 and 2, 500IU/kg/day for 30 days. There were no significant clinical signs such as body weight, food intake, physical and opthalmic examination, urine analysis, etc. Any toxic response was not observed except for enlarged spleen and extramedullary hematopoiesis. No observed adverse effect level (NOAEL) of rHu-EPO for 30 days was considered to be 100IU/kg/day in beagle dogs.

  • The subchronic toxicity study of rHuEPO, a newly developed recombinant erythropoietin, was investigated for 13 weeks in Beagle dogs intravenously treated with doses of 100, 500 and 2,500 lU/kg/day. There were no significant changes in body weight, food intake, physical and opthalmic examination, urine analysis, etc. Any toxic response was not observed except for enlarged spleen and extramedullary hematopoiesis. These results indicate that the no-observed adverse effect level (NOAEL) of rHuEPO is 100 lU/kg in Beagle dogs.

  • The purpose of this study is to define the normal findings of cerebrospinal fluid (CSF) of the clinically healthy Beagle dogs and to provide basic information in diagnosis of neurologic disorders. CSF obtained from 13 clinically healthy dogs was examined for total and differential cell counts, total protein concentration, glucose and lactate dehydrogenase (LDH) concentration, specific gravity, turbidity, and protein electrophoresis. On gross examination, CSF samples evaluated were clear and colorless. Few red blood cells and nucleated cells were present. The mean concentration of glucose and LDH examined were 65.8 mg/dl and 2.7 mg/dl, respectively. The cellular components of CSF samples based on differential counts were monocytes (41.9%), activated macrophages (35.8%), lymphocytes (20.0%), neutrophils (1.6%), and eosinophils (0.7%). The fractions of electrophoretic protein in CSF were albumin (52.7%), alpha-globulin (16.5%), beta-globulin (24.8%), and gamma-globulin (3.0%). Results of albumin quota were ranged from 0.15 to 0.38. In conclusion, this study provided normal composition of CSF in Beagle dogs.

  • This study was performed to determine the toxic effect of DA-3030(granulocyte-colony stimulating factor, G-CSF) in beagle dogs. DA-3030(G-CSF) was injected intravenously at doses of 115 $\mu\textrm{g}$/kg/day, 11.5 $\mu\textrm{g}$/kg/day and 1.15 $\mu\textrm{g}$/kg/day seven days per week for 28 days. After completion of the treatments, the dog were necropsied. The number of dead animal was zero in all groups. No specific clinical sign was found, either. In hematological results, WBC was significantly increased dose-dependently in treated groups. In histopathological findings, megakaryocyte and rubricyte were found in the liver and spleen at the dose of 115 $\mu\textrm{g}$/kg/day. Therefore, we could find the extramedullary hematopoiesis was increased. Megaka yocyte and rubricyte were increased in bone marrow, too. In conclusion, those signs were estimated the pharmacological effect of DA-3030(G-CSF). According to the results, non toxic dose of DA-3030(G-CSF) was higher than 115 $\mu\textrm{g}$/kg/day.

  • The purpose of this study was to evaluate the reliability and validity of the Force-Sensing Resistor (FSR) for measurement of static hindlimb weight distribution in beagle dogs and to compare these results to a Digital Weighing Scale (DWS). Nine healthy beagle dogs were recruited for this study. Static weight distribution was evaluated four times at intervals of 5 days with each device and two observers to calculate the intra- and interobserver reliability. The intraclass correlation coefficient (ICC) values of the FSR for intraobserver reliability were moderate to good (0.74). The results for the DWS showed poor to moderate (0.56) ICC values for intraobserver reliability. The ICC values for interobserver reliability were 0.53 and 0.61 for FSR and DWS, respectively, indicating poor to moderate agreement. Our findings suggest that the Force-Sensing Resistor can be used to measure static weight distribution in veterinary medicine. However, caution should be taken when comparing measured values of static weight distribution obtained utilizing both the FSR and DWS due to their low positive correlation (R = 0.41, p < 0.01).

  • This study was carried out to evaluate the three months subacute intravenous toxicity of water soluble dimethyl dimethoxy biphenylate derivative (DDB-S), a newly formulated therapeutic agent for hepatitis, in Beagle dogs. Groups of 12 male and 12 female dogs were given different dosage of DDB-S, 10 mg/kg/day (high dose group), 5 mg/kg/day (middle dose group), 2.5 mg/kg/day (low dose group) and 0 mg/kg/day (control group) for three months by intravenous route. 1n the three months intravenous toxicity study, there were neither dead animals nor significant changes of body weights during the experimental period. 1n addition to, no significant DDB-S related changes were found in clinical signs, urinalysis and other findings. Statistical changes were observed in hematological. biochemical, partial thromboplastin time (PIT) and organ weight parameters of treated groups. However, these alteration had no relationship with dosage. No histopathological lesions were observed in both control and treated animals. Above data suggest that no observed adverse effect level of test materials in Beagle dogs might be over 10 mg/kg/day in this study.

  • Riboflavin is a water-soluble vitamin, which serves as a precursor to flavin mononucleotide and flavin adenine dinucleotide. This study aimed to develop a simple and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis for the quantification of riboflavin in the Beagle dog plasma. This method utilized simple protein precipitation with acetonitrile and 13C4, 15N2-riboflavin was used as an internal standard (IS). For chromatographic separation, a hydrophilic interaction liquid chromatography (HILIC) column was used with gradient elution. The mobile phase consisted of 0.1% (v/v) aqueous formic acid with 10 mM ammonium formate and acetonitrile with 0.1% (v/v) formic acid. Since riboflavin is an endogenous compound, 4% bovine serum albumin in phosphate buffered saline was used as a surrogate matrix to prepare the calibration curve. The quantification limit for riboflavin in the Beagle dog plasma was 5 ng/mL. The method was fully validated for its specificity, sensitivity, accuracy and precision, recovery, and stability according to the US FDA guidance. The developed LC-MS/MS method may be useful for the in vivo pharmacokinetic studies of riboflavin.

  • Common Embedded boards like the Arduino, Raspberry Pi, BeagleBone Black, leverages smart home systems, machine tools and various products in our day to day life. Managing and dealing frequent large scale incidents involving recent reagents and hazardous materials can be dangerous and difficult to detect in advance like in an event of an accidents or fires. In this paper I have done research by utilizing an Embedded (BeagleBone Black) boards sensors and RFID management system to detect a hazardous situation like fire in real time and avoiding it by sending out an alert message to the admin user to minimizing the risk. This system provides immediate information to the administrator of any hazardous situation and prevents any accidents from occurring.

  • This study was performed to evaluate the acute oral toxicity of an oriental medical prescription for obesity treatment, SH21-B, in Sprague-Dawley rats and Beagle dogs. SH21-B was administered in rats at does of 0mg/kg, 2,000mg/kg, and 5,000mg/kg. And also SH21-B was administered in Beagle dogs at does of 150mg/kg, 300mg/kg, and 600mg/kg. The rats and dogs of both sexes were observed daily for 14 days after single oral administration. Two female rats, one administered at 2,000mg/kg and the other administered at 5,000mg/kg, died, but no dead animal was observed among male rats. Therefore LD50 in the female rat is observed to be 8,710mg/kg, and MLD(Minimum Lethal Dose) of the male rat is observed to be more than 5,000mg/kg. Among dogs, no dead animal was observed up to 600mg/kg and MLD is observed to be more than 600mg/kg.

  • The acute toxicity of rHu-EPO, newly developed recombinant erythropoietin, was tested in beagle dogs. rHu-EPO, when administered intravenously at 25, 000 IU/kg, did not cause any death. Also, rHu-EPO did not induce any change of body weight, food intake and clinical signs compared to controls. There were no significant changes in hematological, urine analysis and pathological examination. These results showed that rHu-EPO did not induce any remarkable toxic response and the $LD_50$ was greater than 25, 000 IU/kg in beagle dogs.
