This study is a part of a work to design a radiographical method to objectively define the conformation of an equine digit and to assess the individual appropriate trimming of a horse. Various angles were measured directly from the phalangeal bones. The authors observed that the bone relief of the sesamoid ligament insertions on the proximal phalanx was an essential landmark to determine the phalangeal alignment. The same angles were measured from specific radiographs and made it possible to quantify the rotation imposed to the proximal phalanx. The authors also noticed that the phalangeal rotation had little influence on the radiographic image of articular asymmetry. [less ▲]

A sensitive and specific double-antibody RIA for a bovine pregnancy-associated glycoprotein (bPAG) is described. The limit of detection was 0.2 ng/ml. The assay was specific for bPAG in that pituitary and placental gonadotropic hormones and other placental or serum proteins assayed in serial dilutions did not cross-react. The RIA allowed measurement of bPAG in placental extracts, fetal serum, fetal fluids, and serum or plasma of pregnant cows. About 20% of unbred heifers and nonpregnant cows had detectable levels ranging from 0.30 +/- 0.09 to 0.50 +/- 0.17 ng/ml (mean +/- SD), and 15% of bull sera showed higher concentrations (3.01 +/- 1.73 ng/ml) of bPAG or bPAG-like protein. Variations among animals was observed in fetal serum bPAG concentrations. Bovine PAG was detected in maternal peripheral blood at Day 22 of pregnancy (mean +/- SD, 0.38 +/- 0.13 ng/ml) in some animals and at Day 30 in all pregnant cows. Peripheral serum bPAG levels increased progressively to 3.60 +/- 1.73 ng/ml (mean +/- SD) at Day 30 of pregnancy, to 24.53 +/- 8.81 ng/ml at Day 120, and to 1551.91 +/- 589.68 ng/ml at Day 270. Peak concentration of bPAG was 2462.42 +/- 1017.88 ng/ml and it occurred 1-5 days prior to parturition. After delivery, bPAG concentrations decreased steadily to 499.63 +/- 267.20 ng/ml at Day 14 postpartum (pp), 10.12 +/- 7.84 ng/ml at Day 60 pp, and 1.44 +/- 1.08 ng/ml at Day 90 pp. The undetectable concentration (less than 0.20 ng/ml) was reached by Day 100 +/- 20 pp. An investigation undertaken in Holstein heifers, Holstein cows, and Hereford cows used as recipients for purebred Holstein embryos supplied evidence of the influence of breed of recipient and sex of fetuses on peripheral concentrations of bPAG. A herd of 430 Holstein-Friesian heifers that had received transferred embryos were bled at Day 35 postestrus (pe) for measurement of bPAG. The bPAG was detected in 287 of 430 serum samples analyzed. By rectal palpation performed at Day 45 pe, 267 heifers with detectable levels of bPAG at Day 35 pe were confirmed to be pregnant as were 3 of 143 heifers previously diagnosed as not pregnant by RIA. These results suggest that detection of this placental-specific antigen in the serum could be used as a specific serological method for early pregnancy diagnosis in cattle from 28 days after breeding.

Concentrations of bovine placental lactogen ( bPL) were determined in fetal plasma samples by twelve double-antibody competitive radioimmunoassay systems ( RIA I - XII) based on either recombinant bPL ( non- glycosylated) or native bPL ( glycosylated). Both preparations were used as standard and tracer, and for primary antisera production. The minimum detection limit measured by these RIA varied from 0.02 to 0.6 ng bPLmL(-1). The coefficients of correlation of different bPL RIA systems were up to 90% ( P< 0.0001) when each RIA was tested against the average values of all twelve RIA systems. All developed RIA were used to investigate the incidence of different bPL isoforms in bovine fetal serum samples ( n= 71). Fetal concentrations ranged from 11.8 to 35.7 ng mL(-1) at the third month and from 1.1 to 13.5 ngmL(-1) at the ninth month of gestation. They tended to decrease with advancing gestation. In general, those RIA systems that used recombinant bPL as the standard measured higher values than those using the native bPL preparation. These differences decreased toward the end of gestation ( P< 0.05), suggesting a lower rate of glycosylation. Our results provide evidence of different glycosylated isoforms of bPL in fetal serum at different gestation periods. [less ▲]

A radioimmunoassay of the undecapeptide substance P (SP) and its application in rabbit lung superfusate has been developed. The assay was based on the use of a radioactive tracer, 125I-SP-Tyr8, which showed, with an excess of antibodies, a specific binding greater than 90% and a nonspecific binding lower than 2%. This tracer was stable for 4 weeks at -20 degrees C. Its specific radioactivity was 384 Ci/mmol. The assay's lower limit of detection was 10 pg/ml (0.7 fmol). The determination of SP in rabbit lung perfusate required extraction and concentration using octadecylsilane cartridges. Under these conditions, the recovery of SP from experiments on lung perfusates (n=4) was 75.0+/-4.5%, and the intraassay and interassay coefficients of variation were 7.3+/-1.9% and 10.7+/-1.3%, respectively. Amounts of SP released in rabbit lung perfusates were determined following stimulation of pulmonary C fibers with capsaicin (10(-4) M). During the stimulation period, the values of SP from lung perfusates (n=6) increased significantly when compared with baseline values. [less ▲]

OBJECTIVES: To assess the impact of radiographic severity and progression on pain and disability. METHODS: Measurements of mean joint space width (JSW), narrowest join space (NJS) point and assessment of symptoms by the WOMAC questionnaire were performed at baseline and after three years in 212 subjects over 50 years with primary knee OA. RESULTS: At baseline, JSW and NJS were not significantly correlated with the scores recorded for the WOMAC global index or its pain, stiffness or function subscales. A statistically significant correlation was observed between the joint space narrowing over three years and the changes observed in the pain subscale of the WOMAC during the same period. The three-year changes in the global WOMAC index in patients within the lowest and the highest quartiles of mean joint space width at baseline showed, in both cases, a statistically (p<0.05) significant favorable difference between patients treated with glucosamine sulphate and those having received placebo. CONCLUSION: Radiographic and clinical progressions of the disease are significantly associated but the clinical relevance of the association is questionable. [less ▲]
