Comparison of Hematologic and Biochemical Test Results in Blood Samples Obtained by Jugular Venipuncture Versus Nail Clip in Moluccan Cockatoos (Cacatua moluccensis).

In birds, blood samples are often collected from the jugular, medial metatarsal, and basilic vein. Samples are sometimes collected by toe nail clip, but concerns to avoid drawing blood from the nail include pain after nail clips for blood collection, potential differences in complete blood count (CBC) results, and potential contamination with uric acid values. To compare differences in biochemical and hematologic values in blood samples obtained by jugular venipuncture versus toenail clip, blood samples were collected from Moluccan cockatoos (Cacatua moluccensis) (N = 23) and sent to a commercial laboratory for routine CBCs and serum biochemical analysis. Results showed good agreement between venipuncture and nail clip blood samples in red blood cell count, packed cell volume, heterophil count and percentage, lymphocyte count and percentage, aspartate aminotransferase, chloride, creatine phosphokinase, glucose, lactate dehydrogenase, total protein, and uric acid values. Constant bias was found in values of bile acids, cholesterol, and hemoglobin. Proportional bias toward higher values in the jugular sample were found in total white blood cell (WBC) count and inorganic phosphorus. Serum calcium plots revealed a proportional bias toward higher values in the toe nail blood when values were increased. Results suggest some differences in WBC count, bile acids, calcium, cholesterol, hemoglobin, and phosphorus values between blood samples collected by jugular venipuncture and samples collected by toe nail clip, but the differences are mostly minor and, with the possible exception of inorganic phosphorus and marginally elevated or very low WBC counts, are unlikely to affect the use or interpretation of the avian blood panel.

Metabolomic investigation of pathogenesis of myxosporean emaciation disease of tiger puffer fish Takifugu rubripes.

Serum biochemical analysis was undertaken to study the pathophysiological details of emaciation disease of the tiger puffer fish Takifugu rubripes (Temminck and Schlegel). Serum parameters were measured by biochemical analysis using automated dry chemistry and gas chromatography/mass spectrometry (GC/MS). Serum concentrations of albumin, amylase, calcium, creatinine, glucose and total protein were significantly lower in the emaciated fish when compared with those of normal fish. Regression analyses found close correlation between concentrations of total protein, albumin, amylase, glucose and progress of the disease. In contrast, serum alanine aminotransferase increased significantly in emaciated fish indicating liver function disorder. Further, GC/MS metabolic profiling of the puffer serum showed that the profile of the emaciated fish was distinct to that of non-infected control. The serum content of amino acids including glycine, 5-oxo-proline and proline, and ascorbic acid, fumaric acid and glycerol increased significantly in serum in moderately emaciated fish. The serum glucose, linolenic acid and tyrosine level decreased significantly in the late phase of the disease. Our results clearly show that prolonged intestinal damage caused by myxosporean infection impairs absorption of nutrients, resulting in extreme emaciation.

Hematological and serum biochemical analyses in experimental caprine besnoitiosis.

This study was undertaken to investigate the hematological and biochemical changes in experimentally infected goats with Besnoitia caprae from the time of infection till 360 days post-infection (PI). Six male goats were inoculated subcutaneously with 13 × 10(7) bradyzoites of B. caprae, and blood samples were collected from the jugular vein. The total erythrocyte and total leukocyte counts, hematocrit value, and differential leukocyte counts were determined. Serum biochemical analysis, including the total protein, albumin, total globulin, cholesterol, triglyceride, chloride, testosterone, calcium (Ca(2+)), inorganic phosphorus, sodium (Na(+)), potassium (K(+)), iron (Fe(2+)), glucose, serum amyloid A (SAA), haptoglobin (Hp), fibrinogen, ceruloplasmin, aspartate aminotransferase, alanine aminotransferase, creatine kinase, lactate dehydrogenase, and alkaline phosphatase, was undertaken. Skin biopsy from the limbs were collected at weekly intervals and histologically examined for Besnoitia cysts. Cysts were present in the skin biopsies of the leg of the infected goats from day 28 PI. There were variations in hematological analyses, but no significant difference was seen. From day 30 to 360 PI, results showed that SAA, Hp, fibrinogen, and ceruloplasmin concentrations increased, whereas testosterone concentrations decreased. Infected goats exhibited decrease of albumin and increase of serum total protein and globulin concentrations. By contrast, there were no significant differences in the remained analyses concentrations.

Long-term biodistribution and toxicity of curcumin capped iron oxide nanoparticles after single-dose administration in mice.

AIM: In this study, in vivo biodistribution, clearness and toxicity of curcumin capped iron oxide nanoparticles (Cur-IONPs) were addressed in different body organs. MATERIALS AND METHODS: The physicochemical properties of the prepared Cur-IONPs were investigated. Long term (3 weeks) biodistribution, clearness and toxicity were assessed for a single-dose administration of Cur-IONPs (5 mg/kg). The iron content in liver, kidney, spleen and brain was quantified using atomic absorption spectroscopy. Serum biochemical parameters were also measured. KEY FINDINGS: The integrated in vivo results demonstrated that Cur-IONPs was mostly taken up in the liver and spleen reaching its highest levels on days 1 and 2, respectively. In the brain, the results showed significant accumulation of Cur-IONPs between 1 h to 1-day post injection. This represented the successful penetration Cur-IONPs across the blood-brain barrier. Serum biochemical analysis demonstrated a temporal disturbance in the performance of body organs. Also, the body weights showed no alteration throughout the experiment. SIGNIFICANCE: It has been deduced that the promising green synthesized Cur-IONPs as an "All in One" nanoplatform is safe enough to be used in diagnostic and therapeutic purposes.
