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 evaluate single and repeated-dose toxicities oj a new cophalosporin antibiotic agent IDC-7l81 in Sprague-Dawley rats. IDC-7181 was injected intravenously to rats at dose levels of 0, 3.2, 16, 80, 400 and 2,000 mg/kg/day for single-dose toxicity study and at dose levels of 0, 10, 50 and 250 mg/kg/day for 4-week repeated-dose toxicity study. In both studies, there were no dose-related changes in mortality clinical signs, body weight changes, food and water consumption, opthalmoscopy, organ weights, urine analysis, biochemical examination, and hematological findings of all animals treated with IDC-7l8l. Gross and histopathological findings revealed no evidence of specific toxicity related to IDC-7181. These results suggest that the intravenous maximum tolerated dose value of IDC-7181 may be over 250 mg/kg and $LD_{50}$ value may be over 2,000 mg/kg in rats.

Eryngium foetidum Linn. leaves (EF) are widely used in Thailand and many countries throughout Asia as a culinary seasoning and a traditional medicine. However, adverse effect of high dose consumption in long duration has not been evaluated. The aim of this study was to investigate chronic toxicity of EF in mice. Thirty-two ICR male mice were divided into 4 groups of 8 mice each. The mice were fed AIN-76 rodent diet, or AIN-76 rodent diet supplemented with ground freeze-dried EF at 0.8%, 1.6% and 3.2% that is equivalent to approximately 35, 73 and 155 times that of human consumption, respectively, at 97.5 percentile for a period of 24 weeks. At the end of experiment, the mice were euthanized and blood samples were collected for hematological and biochemical evaluations. Necropsy was performed while visceral organs such as lung, liver, kidneys, spleen etc. were collected, weighed and histopathologically examined. Blood urea nitrogen (BUN) results of mice in 1.6% and 3.2% EF diet groups were significantly higher than the BUN of control group. No significant difference was noted in other biochemical and hematological properties between the treatment groups and control; all results were within normal range. Histopathology of almost all visceral organs showed no significant changes. However, tubulonephrosis and chronic interstitial nephritis were observed in the groups treated with 1.6% and 3.2% EF diet. Body weight was reduced significantly at week 12 to week 20 when compared to the control group while relative kidney weights were significantly increased. In conclusion, the consumption of EF in diet at high doses illustrated the adverse effect on some biochemical parameters and histopathology in mice. Our findings suggested that EF daily consumption for 24 weeks, at higher doses than the 0.8% EF diet (35 times of human consumption), might cause adverse effect on kidney function in mice.

Severe hypercalcemia is rarely encountered in children, even though serum calcium concentrations above 15-16 mg/dL could be life-threatening. We present a patient having severe hypercalcemia and azotemia. A 14-year-old boy with no significant past medical history was referred to our hospital with hypercalcemia and azotemia. Laboratory and imaging studies excluded hyperparathyroidism and solid tumor. Other laboratory findings including a peripheral blood profile were unremarkable. His hypercalcemia was not improved with massive hydration, diuretics, or even hemodialysis, but noticeably reversed with administration of calcitonin. A bone marrow biopsy performed to rule out the possibility of hematological malignancy revealed acute lymphoblastic leukemia. His hypercalcemia and azotemia resolved shortly after initiation of induction chemotherapy. Results in this patient indicate that a hematological malignancy could present with severe hypercalcemia even though blast cells have not appeared in the peripheral blood. Therefore, extensive evaluation to determine the cause of hypercalcemia is necessary. Additionally, appropriate treatment, viz., hydration or administration of calcitonin is important to prevent complications of severe hypercalcemia, including renal failure and nephrocalcinosis.
