Reference values of hematological and biochemical parameters for the world smallest microminipigs

In this study, we demonstrated growth curves and reference values for hematological and serum biochemical parameters of Microminipigs, the world smallest experimental minipigs. In both male and female animals, the body weights (BWs) at 3 and 6 months of age were <5 kg and <10 kg, respectively, and growth curve revealed almost plateau (approximately 20 kg BW) after 18 months of age. Major hematological and serum biochemical parameters showed no gender differences and the values were very similar to those in G?ttingen and Yukatan minipigs. The values obtained in this study can serve as fundamental reference, and thereby facilitate the use of Microminipig in life science research.

Routine hematology and clinical chemistry in female dogs with benign and malignant mammary tumors

Routine hematological and serum biochemical screening was done in 61 female dogs with benign mammary tumors and 51 female dogs with malignant mammary tumors. Most parameters were not significantly different from age-matched female controls; moreover, no significant difference could be observed between animals with benign and malignant tumors. It is concluded that routine hematology and biochemistry offer little diagnostic or prognostic benefit in female dogs with mammary tumors.

This study was designed to compare the blood physiological and biochemical parameters between plateau Juema minipigs and plain Bama minipigs,and provide a theoretical basis for Juema minipigs served as experimental animals in the future.The blood samples of Juema minipigs were taken in Gannan,and the blood samples of the Bama minipigs were taken in Xi'an,24 blood physiological and biochemical parameters were tested using an automatic analyzer of blood cells and biochemistry.Between the plateau Juema minipigs and Bama minipigs,there were significant differences in PLT,RDW-CV and RDW-SD (P< 0.05) and extremely significant differences in RBC,HGB,HCT,MCH,MCMH,GGT,GLU and CRE (P< 0.01).The plateau Juema minipig had an altitude acclimatization,so it was better than Bama minipig in plateau medical science.     

Biochemical intestinal parameters in germ-free minipigs and rats and in ex-germ-free minipigs and rats monoassociated with Escherichia coli

Intestinal contents of newborn and young germ-free minipigs and germ-free rats were investigated for the following biochemical parameters - conversion of cholesterol to coprostanol, degradation of beta-aspartylglycine, level of tryptic activity, formation of urobilinogen and the profile of short-chain fatty acids. Additionally, germ-free minipigs and germ-free rats were monoassociated with non-pathogenic strains of Escherichia coli and were investigated for the same biochemical parameters. The conversion of cholesterol to coprostanol, degradation of beta-aspartylglycine, tryptic activity and the short-chain fatty acid profile were similar to those found in previous studies in germ-free animals. Slightly higher amounts of urobilinogen than in the other species investigated so far were found in samples from germ-free and monoassociated minipigs. Except for the total amount of short-chain fatty acids in rats, monoassociation with E. coli did not alter any of the parameters either in the minipigs or in the rats.

Sex-based differences in plasma chemistry and cardiac marker test results in Siamese fighting fowl

BACKGROUND: Variations in the results of plasma chemistry analysis as a function of sex have rarely been demonstrated in avian species. OBJECTIVE: The aim of the present study was to investigate sex-related differences in values for routine biochemical variables, including conventional muscle enzymes, and novel cardiac markers in female and male Siamese fighting fowl. METHODS: Plasma chemistry analytes and cardiac marker proteins (creatine kinase-MB and cardiac troponin T) were measured in 70 Siamese fighting fowl using automated chemistry and immunoassay analyzers. Data were compared by 2-tailed t tests between sexes, and Spearman rank correlation between conventional and novel cardiac markers. RESULTS: Male fowl had significantly higher uric acid concentration and gamma-glutamyltransferase activity; whereas, female fowl had significantly higher total cholesterol, triglycerides, and calcium concentrations, and alkaline phosphatase activity. As compared with female fowl, the fighting cocks also had significantly higher plasma concentrations of creatine kinase-MB and cardiac troponin T. Significant correlations between cardiac troponin T, but not creatine kinase-MB, and the activities of conventional muscle enzymes (creatine kinase, aspartate aminotransferase and lactate dehydrogenase) were observed in male but not in female fowl. CONCLUSION: These results indicate that sex-specific differences exist for several biochemical parameters and cardiac marker proteins in fighting fowl, and that such differences should be considered in interpreting laboratory test results.     

Experimental determination and allometric prediction of vitreous volume, and retina and lens weights in Göttingen minipigs

Objectives To determine the vitreous volume, and retinal and lens wet weights in male and female Göttingen minipigs of different age groups. Procedures Vitreous, lens and retina were isolated from fresh minipig eyes. Vitreous volume, lens and retina weight were measured and allometric scaling was utilized to predict these parameters. Results There were no gender differences in body weights or retina and lens weights in the three age groups examined in this study. For vitreous volumes, females had a significantly larger volume (approximately 10%–12%) than males in the 4–6 and 6–8 month, but not in the 8–11‐month group. The mean body weight increased from 12.2 ± 2.6 kg (4–6 months) to 19.4 ± 4.0 kg (8–11 months). In the same period, the mean vitreous volume increased from 2.00 ± 0.28 to 2.67 ± 0.31 mL, while the mean retinal and lens weights increased from 114 ± 22 to 126 ± 17 mg, and from 298 ± 26 to 392 ± 15 mg, respectively. Allometric analysis between six species for vitreous volume and four species for lens weight covering a weight range of 260‐fold was not able to estimate the vitreous volume, but it did predict the lens weight in 8–11 months minipigs. Conclusions Overall these measurements add important context to intraocular pharmacology studies, and will help in the improved design and interpretation of such experiments.
