Öğe Comparative geometrical morphometries on the mandibles of anatolian wild sheep (ovis gmelini anatolica) and akkaraman sheep (ovis aries)(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2010) Yalcin, Hakan; Ali Kaya, Mehmet; Arslan, AtillaAkkaraman sheep (Ovis aries Linnaeus, 1758) are densely breed in the region of Middle Anatolian in Turkey. Anatolian wild sheep (Ovis gmelini anatolica Valenciennes, 1856) is also subspecies of a wild sheep existing in the exact center of these lands and exists as little number only in the place of Bozdag at the east of Konya. In this study, it is aimed that the mandibular bones of the Akkaraman sheep and Anatolian wild sheep are compared for morphologic and geometric morphometrics. In this study, the mandibular bones of 16 Anatolian wild sheep and 10 specimen Akkaraman sheep were used. In this study, the mandibular bones of the species were appeared quite similar. The geometric morphometrics analysis clearly determined the morphological differences between both species. On the lateral direction of the mandibular bones of each species, mutual ten each pieces homolog landmarks were used. In the analysis of the relative warp, RW1 explained 56.46% of total variation and RW2 explained 11.40% of total variation. Evident differences were determined among all of the homologous landmarks (except to anterio-ventral corner's point of P(2) tooth) used at the mandible of Anatolian wild sheep and Akkaraman sheep. As the most evident, firstly, posterio-ventral corner of M(3) tooth and homologous landmarks in the levels of anterior directed combination of lines of the angel for the vessels and dorsal-ventral masseteric ridges were observed..Öğe Morphometric effects of the combined usage of anabolic androgenic steroids on humerus(SILA SCIENCE, 2012) Lok, Sefa; Tasgin, Erdal; Yalcin, HakanThis study has carried out to examine the effect of the combined usage of anabolic androgenic steroids consumed by athletes on humerus. In this study, twenty-four New Zeland white rabbits were used. Male and female rabbits were separated into two groups. Control group (male n: 6, female n: 6) was fed during 12 weeks without being made any application. 10 mg/kg if testosterone plus 10 mg/kg of nandrolone deaconate were intramuscularly applied on experimental group (male n: 6, female n: 6) one day in a week during 12 weeks. Front extremity bones of materials were revealed by making diseke and were subjected to maceration operation. Upon examining the lengths of humerus bones, growth of the humerus bone has evidently suspended among the subject males that are consumed the drug and the difference has been found significant (p < 0.05). Among males the growth of the length of humerus bones has suspended significantly but among females the same effect has not examined. In conclusion, combined usage of these two steroids may enhance the effects of the testosterone, and thus the relative results are found significant among males comparing to females.
