Mineral Status of Myocardial Sarcocystosis

Background

The role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. For these reasons, the present research was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009.

Methods

Blood and heart tissue samples were collected from 145 slaughtered sheep and histopathological findings were confirmed as myocardial sarcocystosis in 27 cases. Serum and tissue mineral level were determined by atomic absorption spectroscopy. Data were analyzed by Sigmastat program, using One Way Analysis of Variance (ANOVA) at the level of P<0.05.

Results

Myocardial sarcocystosis significantly increase myocardial concentration of Cu, Zn and Fe (P<0.05).

Conclusion

These findings may explain the role of copper, zinc and iron in parasite persistency and may discuss the pathogenesis of sarcocystosis, which relates to evocate mentioned micronutrient to cardiac muscle.     

Cephalometric and craniometric age changes in adult humans

Thirty-three cephalometric and craniometric measurements were made on lateral radiographs of 154 males and 199 females, aged 21-83 years, from Vienna, Austria. The measurements were studied in age-groups by univariate and multivariate analyses. The results showed that the height dimensions of the face and viscerocranium increase up to the fourth decade but then decrease, while the height dimensions of the neurocranium decrease progressively with advancing age. However, the latter findings could possibly also reflect a secular trend. The thickness of the soft tissues showed continuous increases throughout the series, especially along the lower face. Although the age changes were greater in cephalometric than in the craniometric dimensions, those of the skull were also statistically significant. Using discriminant analysis on the cephalometric data results in correct assignment of 63.32% of females to their age-group but only 58.44% in males. The higher correct assignment of the females could have been due to their larger sample size.
