A study was undertaken to establish the ranges of prostate dimensions, weight and volume in mature normal dogs and thus provide information which would allow differentiation from normality of size changes associated with disease. The study was performed on 154 healthy adult male entire dogs. Each prostate was imaged ultrasonographically and standard longitudinal and transverse sections were obtained. Prostate length (L), depth on longitudinal (DL) and transverse sections (DT) and width (W) were measured. Prostatic volume and weight were estimated according to formulae derived previously. There were statistically significant correlations between bodyweight or age and L, DL, DT and W. There were also significant correlations between estimated prostatic weight or volume and bodyweight, age, L, DL, DT and W. Formulae were derived to express the relationships between prostate size (weight or volume) and age or bodyweight.

This study was designed to investigate whether kits to measure circulating cardiac troponin-I (cTn-I) and cardiac troponin-T (cTn-T) can be used to determine myocardial cell damage in cattle with traumatic reticuloperitonitis (trp). Twenty cattle with trp were compared with 10 clinically healthy cattle. cTn-I and cTn-T were determined qualitatively and cTn-I was determined quantitatively; biochemical analyses were also performed on both groups. The mean serum concentrations of total protein, globulin, glucose and calcium, and the mean activities of creatine kinase mb, aspartate aminotransferase, lactate dehydrogenase and gamma-glutamyl transferase were higher in the cattle with trp than in the control group. The cTn-I and cTn-T kits both gave positive results in three of the cattle with trp and the quantitative measurement of cTn-I was positive in 11 of the trp cases. Both tests were negative in the healthy cattle.

The purposes of this study were to: 1) compare prostatic dimensions measured on radiographic and ultrasonographic images and 2) compare a subjective radiographic assessment of prostate size with a previously-described objective method. Thirty-four male dogs undergoing investigation of prostatic disorders were used. Prostate length and depth were measured from ultrasonographic and radiographic images. A subjective assessment of prostate size ('small', 'normal', or 'enlarged') was made in 29 animals by one of the authors who was unaware of radiographic or ultrasonographic measurements. In addition, the distance from sacral promontory to the pubic brim was also measured. A prostate length or depth of >70% of this distance was defined as 'enlarged' and <70% as 'normal'. After the effects of magnification on radiographic measurements were eliminated, there were no significant differences between prostatic length measured by the two methods. However, a significant difference was obtained between prostatic depth measurements. The subjective assessment agreed with a previously described objective assessment of prostatic size in 21/29 dogs for prostate length but in only 12/29 for depth. Prostatic length varied from 46.6 to 116.4% (mean 75.7%) of the distance from the pubic brim to the sacral promontory. Prostatic depth varied from 33.0% to 94.6% (mean 59.7%) of the same distance. It is recommended that prostate length, rather than depth, be used when evaluating prostate size from lateral abdominal radiographs.
