Blood samples were collected from 91 rusa deer (Cervus timorensis russa), immediately after being shot. Serum mean biochemical values from shot deer are presented for blood urea nitrogen, creatinine, creatine kinase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, total protein, albumin, calcium, and phosphorus. Mean total protein and albumin increased with age. There was an age-associated increase of gamma globulins. Mean creatine kinase activity and creatinine, albumin and phosphorus concentrations were higher in stags than in hinds. Pregnant hinds had lower mean creatine kinase activity and phosphorus and higher mean alanine aminotransferase and total protein than non-pregnant hinds. Mean calcium concentration increased when deer were agitated before bleeding.

1. The prairie dog has been used extensively for the study of gallstone genesis and gallstone dissolution therapies, and has recently been implicated in an effort to prevent total parenteral nutrition-associated cholelithiasis with intravenous chenodeoxycholate. 2. Towards this effort, it is important that a range of normal blood chemistry values be reported for the prairie dog. This paper reports the mean values for a complete blood cell count, electrolytes, blood urea nitrogen, creatinine, calcium, phosphorus, liver enzymes, total bilirubin, protein, albumin, cholesterol, triglycerides and lipids for 45 adult prairie dogs. 3. The prairie dog has normochromic, microcytic blood with an increased number of red blood cells. The prairie dog also has a high concentration of small platelets. 4. The prairie dog has a higher CO2 concentration with a slightly increased potassium concentration than is found in man. The anion gap is 12 with a calculated serum osmolality of 316. The BUN concentration is elevated with a 3-fold increase in the AST concentration. 5. The prairie dog has lower serum values for cholesterol, VLDL and LDL cholesterol than man. In the prairie dog, HDL cholesterol consists of 67% of the total cholesterol concentration and the LDL and HDL ratio is 0.3.

Duchenne muscular dystrophy (DMD) is a fatal disease for which there is no effective treatment. The cause of death in patients with DMD is often cardiovascular and pulmonary dysfunction. This clinical observation, combined with experimental findings, suggests that other non-muscle organ systems may be affected in the dystrophic disease state. To test this hypothesis, the present study investigated liver and kidney function in the mdx mouse. Serum chemistries and the hepatic cytochrome P-450 system in normal and dystrophic mdx mice were investigated at two different ages. Increases in serum lactate dehydrogenase (LDH), alkaline phosphatase (AP), aspartate transaminase (AST), and cholesterol levels, combined with an increase in liver weight and a decrease in cytochrome P-450, suggests the possibility of hepatic dysfunction. Increases in serum uric acid and phosphorus, and decreased kidney weight suggest hepatic dysfunction.

A moderate malignant hyperthermia developed in a Labrador Retriever anaesthetized with isoflurane for a femoral shaft fracture repair. Signs of malignant hyperthermia included progressive increases in PETCO2 and rectal temperature up to 39.8 degrees C, tachycardia, cyanosis, and elevated serum levels of potassium, inorganic phosphorus, AST, CK and alkaline phosphatase. Treatment initiated in the early recovery period consisted of hyperventilation with 100% oxygen, stomach lavage with iced water, body surface cooling, and intravenous administration of cold isotonic saline solution. Cooling was continued until the rectal temperature had dropped to 37.3 degrees C. After treatment the dog recovered uneventfully. Clinical signs, pathophysiology, therapy, prevention of malignant hyperthermia and its association with other disorders are discussed.

Six HK (high erythrocyte potassium) and 7 LK (low erythrocyte potassium) dairy cows were subjected to a 4-h intravenous infusion of 4.7% Na2EDTA solution to induce and maintain hypocalcaemia. Blood samples taken immediately before infusion, hourly for 7 h, and at 24 h after commencement of infusion were subjected to determination of concentration (or count) of 16 analytes. The mean changes in concentrations (or counts) of the various blood analytes were calculated for the periods 0-4, 4-7, 7-24, and 0-24 h after commencement of the infusion for all cows combined, and then separately for the HK and LK groups of cows. Plasma Ca(PCa), plasma inorganic phosphorus (PiP) and plasma potassium (PK) showed significant decreases during the 4-h infusion period and were still below pretreatment levels 24 h later. AST, CPK, PCVs and white cell-counts (WCCs) showed significant early increases which were still significantly elevated 24 h later. Plasma magnesium (PMg) and erythrocyte Na(ENa) and K(EK) all showed delayed changes which still persisted 24 h later. Significant between-group differences were present for PCVs which increased significantly more in the LK than the HK group during the infusion period, for PCa which showed a greater increase in the HK cows than the LK cows during the 4-7 h early clinical recovery period, and for plasma bilirubin (PBil) which showed a greater increase from 0 to 24 h in the HK group than in the LK group. Urine samples, collected before infusion, 4-7 h and 24 h after commencement of the infusion, were subjected to analysis for glucose, protein, pH, 'blood' and ketones. Most cows showed increases in urinary glucose, protein and 'blood'.

Serum chemistry values were obtained from 64 adult San Joaquin kit foxes (Vulpes macrotis mutica) in western Kern County, California (USA). The goal of the study was to establish normal chemistry values for this endangered species. No significant differences were found for mean values of alanine aminotransferase (217.1 IU/l), alkaline phosphatase (44.2 IU/l), cholesterol (145.6 mg/dl), total protein (5.8 g/dl), creatinine (0.63 mg/dl), calcium (8.2 mg/dl), albumin (3.0 g/dl), glucose (129.2 mg/dl), amylase (196.8 IU/l), sodium (153.7 mEq/l) and phosphorus (5.42 mg/dl) between sexes or seasons. Significant differences were noted for aspartate aminotransferase, blood urea nitrogen and potassium between seasons. Possible disturbances in normal hepatic and renal functions were noted.

Mithramycin (0.1 mg/kg) was administered intravenously to eight Beagle dogs on days 0 and 7 to determine its effects on calcium and phosphorus metabolism, serum parathyroid hormone concentration, osteoclastic bone resorption, and serum biochemical and hematologic parameters. Ionized calcium concentration was paradoxically increased on day 1 and decreased on day 8 in association with an increased serum parathyroid hormone concentration. Serum phosphorus concentration was decreased on days 1 and 2. Osteoclastic bone resorption in iliac cancellous bone was significantly decreased on day 8. There were mild increases in serum alkaline phosphatase (days 1, 2, 4, 8, 9), aspartate aminotransferase (day 9), and gammaglutamyl transpeptidase (days 7, 9) activities. Platelet numbers were increased on days 7 through 13, and packed red blood cell volumes were mildly decreased. This investigation demonstrates that two doses of mithramycin can be administered safely to dogs and may inhibit bone resorption in diseases associated with increased osteoclastic bone resorption, such as humoral hypercalcemia of malignancy.

Eight hundred broilers were examined to define the reference values of nine blood constituents (total proteins, albumin, total and free cholesterol, triglycerides, aspartate aminotransferase (AST), alkaline phosphatase (ALP), calcium, and phosphorus). The broilers, coming from 20 different commercial poultry operations, were equally divided into different groups according to age (21 and 45 days), strain (Arbor Acres and Hybro), sex, and sampling season (summer or winter). Age and sampling season were the variation sources that most influenced the values of the hematochemical variables examined. The interaction of age with strain influenced total proteins total and free cholesterol, triglycerides, and ALP. The interaction of age with sampling season influenced all hematochemical constituents except triglycerides. Reference limits defined by .975 and .025 fractiles were computed for each blood constituent according to the significance of different variation sources and their combinations. Reference limits defined herein could be used as indicators of metabolic and health conditions of a poultry farm.

Egyptian scorpion venom was collected by electrical stimulation of the telson. Rats were injected with the lyophilized venom in 3 different doses (100, 200 and 400 micrograms/kg). Blood samples were drawn by heart puncture before and 4 h after venom administration. Serum was separated and collected for determination of glucose, blood urea nitrogen (BUN), creatinine, uric acid (UA), total proteins, cholesterol, sodium, potassium, calcium, inorganic phosphorus, alkaline phosphatase, aspartate aminotransferase (AST, GOT), alanine aminotransferase (ALT, GPT), lactate dehydrogenase and creatine phosphokinase (CPK). Serum glucose, creatinine, GOT, GPT and LDH were increased significantly in all treatments. At the same time serum BUN and CPK were elevated significantly with a dose-response relationship. On the other hand, serum total proteins, uric acid, cholesterol, calcium and potassium were significantly decreased 4 h after administration of the 3 doses. These changes in clinical chemistry parameters are most probably related to the toxic effect of the venom on the target organs.

Blood samples were collected from v. jugularis in five-day intervals from parturition to postpartum day 45 in the rearing conditions of a dairy cow production herd, consisting of 10 groups with 10 pluriparous cows each (crossbreds of Bohemian Pied cattle with Holstein-Friesian cattle). In blood serum the following activities were determined photometrically: aspartate aminotransferase--AST (0.36-0.47 mukat.l-1), gamma-glutamyl transferase--GMT (0.50-0.83 mukat.l-1) and lactate dehydrogenase--LD (7.22-9.10 mukat.l-1); their average values were at an almost constant level. Only did AST and GMT values decrease slightly from day 25 after parturition. The glucose average content on the day of parturition (4.07 mmol.l-1) steeply decreased to postpartum day 5 (2.79 mmol.l-1), and later on, it increased irregularly. The average values of total protein (66.7-73.2 g per 1) slightly increased from postpartum day 20. The values of urea (2.33-2.37 mmol.l-1) and bilirubin (3.49-5.15 mmol.l-1) did not show any larger changes in dependence on the time elapsing from parturition. The average content of creatinine (124-162 mmol.l-1) increased irregularly from postpartum day 15 and then it decreased. Cholesterol concentrations were gradually increasing from 2.58 mmol.l-1 on the day of parturition to 4.99 mmol.l-1 on day 45 after parturition. The average contents of calcium (2.20-2.66 mmol.l-1) and phosphorus (1.75-2.27 mmol.l-1) were irregularly increasing until day 20 after parturition. Also the average content of magnesium (0.86-1.15 mmol.l-1) rose from day 25 after parturition.
