Selected serum constituents were analyzed from 50 adult mallards (Anas platyrhynchos) of both sexes during several stages of reproduction: pre-egg laying, egg laying, incubating, molting, and postreproductive. Similar assays were conducted on sera from ducklings aged 5 to 58 days. Values for total protein (TPR), albumin (ALB), glucose (GLU), gamma-glutamyl transferase (GGT), calcium (CA), phosphorus (PHOS) and magnesium (MG) differed by sex. When all data were combined and analyzed for sex-related differences within each reproductive condition separately, all assays except lactate dehydrogenase (LD-L), cholinesterase (CHE), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CRN) and direct bilirubin (BIDI) differed between sexes during one or more reproductive periods. Each assay showed differences among the various reproductive conditions regardless of gender. The pattern of change differed between sexes. All assays except ALB, GLU, CA and MG showed age-related changes. Lipemia in the sample interfered with all chemistries except TPR, LD-L and CA. Results indicate that when using clinical chemistry as a diagnostic tool in the mallard, age and reproductive condition should be determined in order to compare the data to appropriate control values.

Hematologic and serum biochemical values were determined in blood samples from 217 donkeys (Equus asinus). Donkeys were classified on the basis of size, sex, age, and whether they were domestic or feral. Parametric (mean +/- 2 SD) and nonparametric (2.5th to 97.5th percentile) reference ranges were calculated for each analyte. For all donkeys, 26 of 46 analytes significantly departed from gaussian distribution. Serum lactate dehydrogenase activity in miniature donkeys was higher than that in other donkeys. Differential leukocyte counts in feral donkeys differed from those in other types in ways that suggested that the former had smaller parasite loads or experienced greater stress. Erythrocyte, lymphocyte, and platelet counts and fibrinogen, glucose, inorganic phosphorus, and potassium concentrations decreased with age. Eosinophil counts, mean corpuscular volume, and plasma protein, serum protein, and serum globulin concentrations increased with age. Female donkeys had significantly (P less than 0.05) higher mean corpuscular hemoglobin concentration and leukocyte and neutrophil counts than did male donkeys. Mean corpuscular hemoglobin increased with age, and females had higher values than did males of all age groups. An interaction between age and sex was observed for alkaline phosphatase activity, with a trend for decreased activity with age.

Thirteen biochemical parameters and five enzymatic activities were determined on sera of 63 normal human fetuses sampled by direct puncture under ultrasound guidance, between the 20th and the 26th wk of gestation, and on their mothers. They were referred to us for various prenatal diagnoses but were well and confirmed healthy at birth. Some parameters were found to be very similar in both groups, mainly creatinine, calcium, creatine kinase, aspartate aminotransferase, and gamma-glutamyl transferase. Some values were significantly higher in the fetuses, such as total bilirubin, direct bilirubin, phosphorus, lactic dehydrogenase and alkaline phosphatase activities, and alpha-fetoprotein. Urea, uric acid, glucose, triglycerides, cholesterol, total protein, and albumin levels were found to be lower in fetuses. These data indicate a slower metabolism in fetuses compared to their mothers, a lower level of energy requirement, and a relative liver immaturity. These normal values of fetal biochemistry will improve our knowledge of physiology and help to determine the specific values of a test in fetal pathology.

The health status of broilers fed diets with varying protein contents in the presence of ochratoxin A (OA) were evaluated using clinical-chemistry techniques for blood analysis. A completely randomized, 3 x 4 factorial design was utilized: 14, 18, 22, and 26% of dietary protein and 0, 2, and 4 mg/kg of OA. The broilers were raised to 3 wk of age, at which time blood was collected and various hematological parameters were evaluated. The serum was analyzed for various enzyme activities and for concentrations of metabolites and minerals using an automated, clinical-chemistry analyzer and an atomic-absorption spectrophotometer. Adding OA to the diets of broilers decreased the hemoglobin concentration, corpuscular volume, and the activity of serum alkaline and phosphatase but increased the activity of gamma-glutamyl transferase. Adding protein to the diet increased the activity of the serum aspartate aminotransferase, creatine kinase, and alkaline phosphatase. Adding OA to the diet of broilers decreased the concentrations of serum total protein, as well as the concentrations of albumen and cholesterol and increased the concentrations of serum creatinine and uric acid. The concentrations of serum total protein, albumin, urea nitrogen, and triglyceride were increased by adding protein to the diet. The concentrations of calcium, potassium, and inorganic phosphorus in the serum decreased when OA was added to the diet; but the concentrations of calcium and potassium content in the serum increased along with dietary protein. A regression analysis suggested that dietary protein was synergistic toward OA with regard to the blood levels of cholinesterase, lactate dehydrogenase, and glucose.(ABSTRACT TRUNCATED AT 250 WORDS)

Biochemical and cytological responses in the broncho-alveolar lavage fluid were investigated after instillation of cadmium oxide (CdO) or cadmium chloride (CdCl2) into the rat lung. Although biochemical responses of the lung to CdO were similar to the CdCl2-exposed lung, cytological response was more sensitive to CdO than CdCl2. Increases of lactate dehydrogenase, protein content and number of cells in the lavage fluid were proportional to the dose over the range of 0.5-10 micrograms Cd/rat. beta-Glucuronidase activity in the fluid increased with dose at low doses of Cd, but the activity did not continue to increase above 2 micrograms Cd/rat. A dose-response profile of phosphorus content in the lavage fluid, which might indicate amount of surfactant produced by Type II cells was similar to that observed for beta-glucuronidase in CdO-treated rats. Thus, tolerable level of instilled CdO for the rat lung was about 2 micrograms Cd/rat.

To get normal reference ranges for blood chemistry in elderly subjects, laboratory data on serum chemical analytes obtained from 1822 male and 1870 female outpatients were statistically analyzed with a non-parametric method with iterative truncation. Regarding the difference in the test data between male and female, the values for most analyses except for inorganic phosphorus and total protein were significantly higher in male than in female when an adult group including subjects of age ranging from 21 to 50 years was compared. The values for lactic dehydrogenase, albumin, sodium and calcium were higher in female of over 50 years of age than in their counterpart. When male and female were combined, the normal reference ranges for lactic dehydrogenase, alkaline phosphatase, uric acid, blood urea nitrogen, creatinine and potassium tended to be elevated while those for total protein, albumin and calcium to be declined with ageing. The values for total cholesterol and triglyceride reached a peak at a certain age. Total and direct bilirubin, sodium and chloride values were constant throughout whole age categories.

Metabolic and hormonal responses of eight adult male collared peccaries (Tayassu tajacu) to an ad libitum diet intake, or 25% of an ad libitum intake, were examined. Blood samples for hematological, serum-biochemical and hormonal profiles were collected at three week intervals during the nine week experiment starting 4 August 1983. Males fed on the restricted diet lost an average of 26% of their body weight during the trial, compared to a slight weight gain for those fed ad libitum. Characteristics of the red and white blood cell populations were not influenced by diet intake, with the exception of mean corpuscular volume, which was consistently lower amongst males fed on the restricted diet. Restricted food intake resulted in significantly elevated serum values for urea nitrogen, urea nitrogen:creatinine, urea index, alpha globulin:beta globulin, gamma globulin:albumin, nonesterified fatty acids, alkaline phosphatase and lactate dehydrogenase isozymes (LD1 and LD2). Restricted food intake resulted in significantly lowered serum values for total alpha globulin, alpha-1 globulin, total beta globulin, beta-1 globulin, beta-2 globulin, glucose, triglycerides, calcium, magnesium, sodium, chloride, copper and triiodothyronine. Serum levels of creatinine, total protein, albumin, alpha-2 globulin, uric acid, total bilirubin, cholesterol, aspartate aminotransferase, alanine aminotransferase, gamma glutamyltransferase, lactate dehydrogenase, phosphorus, calcium:phosphorus, potassium, iron, zinc and thyroxine were unaffected by diet intake level. Semen evaluation indicated spermatogenesis was not affected by dietary restriction despite reductions in scrotal circumference and ejaculate gel volume. Serum testosterone levels were significantly lower among males fed on the restricted diet after nine weeks. These data suggest male libido might be depressed during poor range conditions, while maintenance of spermatogenesis might permit them to take immediate advantage of improved range conditions. Blood analysis of metabolic and hormonal function can provide useful information for predicting the adult male's nutritional and reproductive condition.

The effect of cadmium administration on female Bufo regularis was studied. The median lethal doses were 22, 18, 15 and 6.2 mg Cd2+/kg after 24, 48, 72 and 96 hr respectively. After a single intramuscular injection of 6.2 mg Cd2+/kg (representing 96-hr LD50), the results indicated that Cd2+ causes severe physiological abnormalities to this experimental animal. The serums alanine aminotransferase (AlAt), aspartate aminotransferase (AAt), alkaline phosphatase (AlP) and lactic dehydrogenase (LDH) were elevated while the calcium serum was not influenced by Cd2+ throughout the experimental period. On the other hand, phosphorus, total protein and total bilirubin were increased. EDTA treatment (0.2 mmole/kg) protected female toads from mortality up to 20 mg Cd2+/kg. It overcame the physiological alterations that were caused by the Cd2+ injection. This may be due to the fact that Cd2+ is bound to EDTA in a strong complex which is readily excreted via the kidneys.

The functional state of the musculo-skeletal system of healthy male volunteers of three age groups (Group 1--19-21 years, n = 16; Group 2--25-43 years, n = 26; Group 3--48-59 years, n = 30) was evaluated. The subjects were kept in an enclosure for 30 days. Creatine phosphokinase (CPK), lactate dehydrogenase (LDH), alkaline phosphatase, aspartate aminotransferase (AAT), calcium, P1 were measured in blood. The test subjects of the three groups showed a decrease of CPK, LDH, AAT and creatinine. The correlation coefficient between the enzymes varied from 0.64 to 1.00. By the end of the study alkaline phosphatase increased in the Group 1 and 2 subjects and decreased in the Group 3 subjects. Calcium variations were less distinct. The Pi content declined significantly in the Group 3 subjects. Some of the Group 3 subjects who performed regular exercises during the study exhibited smaller decreases of CPK, LDH, AAT and greater stability of calcium and phosphorus.

Methylenedioxymethamphetamine (MDMA) was administered to dogs and rats orally once a day for a 28-day period to evaluate the morphological and neuropathological effects. Major clinical signs associated with the administration of MDMA in the dog included circling, depression, dilated pupils, hyperactivity, rapid breathing, and salivation. Major clinical signs in the rat included hyperactivity, excitability, piloerection, exophthalmos, and salivation. Gross observations at necropsy in the dog possibly related to administration of the test article included reduced testicular size (one high and one medium dose) and prostatic enlargement in two high-dose animals. No gross lesions were seen in the rats at necropsy. The medium- and the high-dose groups in both sexes in both the rats and the dogs gained significantly less weight than the control and low-dose groups. Food consumption decreased the first week for the high- and medium-dose groups, but a significant reversal toward more normal consumption was noted in the following weeks in both the rats and the dogs. Hematologic, clinical chemistry, and urinalysis values did not appear to be affected by the administration of the test article in the dog. In the rat clinical pathology variables showing a trend to decrease with dose included urinary pH, blood urea nitrogen, glucose, creatinine (females), lactate dehydrogenase (LDH) (females), and chloride. Clinical pathology variables showing a trend to increase with dose included total white blood cell count and phosphorus. Microscopically, testicular atrophy was present in one medium-dose and two high-dose male dogs. Prostatic hyperplasia was present in two high-dose male dogs. No test article-related lesions were seen in the brains of either species.
