The activity of the intestinal and hepatic fractions of the serum alkaline phosphatase was studied in 78 patients with acute diseases of organs of the abdominal cavity and in 20 practically healthy people. The character of changes in the activity of the isoenzymes can serve as a reliable evidence of the predominant localization, the degree of the disease and of the inflammatory destructive process, contributes to earlier recognition of acute disease of organs of the abdominal cavity.

A 409-base pair (bp) DNA fragment derived from the msp-1 beta gene of Anaplasma marginale was amplified and simultaneously labeled with digoxigenin-11-dUTP by a polymerase chain reaction (PCR) assay. The resulting digoxigenin-labeled 409-bp PCR product was used as a probe for slot-blot and in situ hybridization to detect A. marginale DNA from experimentally infected bovine erythrocytes. The hybrid formation was detected with alkaline phosphatase-conjugated anti-digoxigenin antibody and substrates 5-bromo-4-chloro-3-indolyl phosphate and nitroblue tetrazolium salt. In slot-blot hybridizations, the probe detected A. marginale DNA from approximately 1,000-10,000 infected erythrocytes in 1.25 ml of whole blood, which is equivalent to a parasitemia level of 0.00001%. The probe proved to be a A. marginale-specific when tested with 17 species of microorganisms. The applicability of the probe for diagnosis was tested by screening A. marginale infections in 2 experimentally infected splenectomized cattle before microscopically detectable parasitemias and after acute infection. After inoculation of infected blood, A. marginale infections were detected with the probe 14 days prior to detection in stained smears. Microscopically inapparent parasitemias were also detected with the probe for 2 months after acute disease. When the probe was used for in situ hybridization on methanol-fixed blood smears, probe reaction could be visualized with light microscopy on A. marginale inclusions within infected erythrocytes. The probe reaction was not observed on leukocytes and uninfected erythrocytes from infected blood smears, on erythrocytes from uninfected blood samples, or on samples infected with A. ovis, Babesia bovis, or B. bigemina. This PCR-mediated nonradioactive probe appears to be a sensitive diagnostic test for A. marginale.

The oldest olds, including centenarians, are increasing worldwide and, in the near future, will represent a consistent part of the population. We have studied bone status and metabolism in 104 subjects over 98 yr of age to evaluate possible interventions able to avoid fragility fractures and disability. Ninety females and 14 males not affected by any acute disease were considered. After a complete clinical assessment, blood was drawn for evaluating bone turnover markers, and performance tests together with skeletal ultrasonography (either at the phalanges or at the heel) were performed. We found that 38 subjects had sustained a total of 55 fractures throughout their lives, and 75% of these were fragility fractures. Twenty-eight fractures occurred at the proximal femur, with 14 after the age of 94 yr. Serum 25-hydroxyvitamin D was undetectable in 99 of 104 centenarians. PTH and serum C-terminal fragment of collagen type I were elevated in 64 and 90% of centenarians, respectively, with a trend toward hypocalcemia. Bone alkaline phosphatase levels were close to the upper limit. Serum IL-6 was elevated in 81% of centenarians and was positively correlated with PTH and negatively correlated with serum calcium. Serum creatinine was not correlated with PTH. Bone ultrasonography showed that most centenarians had low values, and ultrasonographic parameters were correlated with resorption markers. We conclude that the extreme decades of life are characterized by a pathophysiological sequence of events linking vitamin D deficiency, low serum calcium, and secondary hyperparathyroidism with an increase in bone resorption and severe osteopenia. These data offer a rationale for the possible prevention of elevated bone turnover, bone loss, and consequently the reduction of osteoporotic fractures and fracture-induced disability in the oldest olds through the supplementation with calcium and vitamin D.

Clinical-chemical traits are diagnostic parameters essential for characterization of health and disease in veterinary practice. The traits show significant variability and are under genetic control, but little is known about the fundamental genetic architecture of this variability, especially in swine. We have identified QTL for alkaline phosphatase (ALP), lactate (LAC), bilirubin (BIL), creatinine (CRE) and ionized sodium (Na(+)), potassium (K(+)) and calcium (Ca(++)) from the serum of 139 F(2) pigs from a Meishan/Pietrain family before and after challenge with Sarcocystis miescheriana, a protozoan parasite of muscle. After infection, the pigs passed through three stages representing acute disease, subclinical disease and chronic disease. Forty-two QTL influencing clinical-chemical traits during these different stages were identified on 15 chromosomes. Eleven of the QTL were significant on a genome-wide level; 31 QTL were chromosome-wide significant. QTL showed specific health/disease patterns with respect to the baseline values of the traits as well as the values obtained through the different stages of disease. QTL influencing different traits at different times were found primarily on chromosomes 1, 3, 7 and 14. The most prominent QTL for the investigated clinical-chemical traits mapped to SSC3 and 7. Baseline traits of ALP, LAC, BIL, Ca(++) and K(+) were influenced by QTL regions on SSC3, 6, 7, 8 and 13. Single QTL explained up to 21.7% of F(2) phenotypic variance. Our analysis confirms that variation of clinical-chemical traits is associated with multiple chromosomal regions.
