    (Sağlık Bilimleri Enstitüsü, 2008) Karakurum, Emine; Dursun, Nejdet; Anatomi
    Macroanatomic Investigation of the Celiac Artery and Its Branches in Donkey (Equus asinus)In this study arteria celiaca of ten donkeys was investigated. All materials were filled with latex and dissected.It was observed that a. celiaca was originated from ventral wall of aorta abdominalis at the level of hiatus aorticus. Firstly a. hepatica leaved and after this a. gastrica sinistra leaved and runs as a. lienalis.It was determined that a. hepatica was first leaved a. celiaca alone and originated from the right root.It was detected that a. hepatica gives rr. pancreatici to pancreas, runs ventrally and at the level of vena porta gives r. hepaticus and runs as a. gastroduodenalis, finally a. gastroduodenalis separated to a. gastroepiploica dextra and a. pancreaticoduodenalis cranialis. It was determined that rr. pancreatici took also origin from a. gastroduodenalis and a. pancreaticoduodenalis cranialis. It was observed that in one material a. gastica dextra originated from a. hepatica, in one material from a. gastroduodenalis, in three materials from the branch of r. hepaticus which courses to lobus hepatis sinister and in five materials from r. hepaticus.It was seen that a. gastrica sinistra was thinner when compared with a. hepatica and a. lienalis, and also originated from a common root with a. lienalis.It was determined that a. gastrica sinistra seperated to r. parietalis and r. visceralis at dorsal and ventral aspect of pars cardiaca of gaster. In four materials r. esophageus originated from r. parietalis, in six materials from r. visceralis.It was established that a. lienalis runs as a part of a. celiaca and when compared thicker than a. hepatica and a. gastrica sinistra. It was determined that a. lienalis originated from a common root with a. gastrica sinistra.It was observed that a. lienalis gives rr. pancreatici to pancreas and after runs to extremitas dorsalis of lien, courses to extremitas ventralis at hilus lienalis and during this course it gives aa. gastricae breves, rr. splenici, and rr. epiploici. It was determined that a. lienalis runs as a. gastroepiploica sinistra after extremitas ventralis of lien and from this vessel aa. gastricae breves and rr. epiploici originated.

    The qualitative and quantitative assessment of the renal cortex of the clinically healthy rabbits

    Qualitative ultrasonographic images in diagnosing renal parenchymal diseases can be inadequate. The relationship between renal cortical echogenicity and parenchymal disease has been demonstrated in people. However, it is difficult to determine diffuse fat vacuoles and the parenchymal diseases at qualitative renal assessment. Disorders of the renal cortex are frequently seen in rabbits. The aim of this study was to qualitatively and quantitatively evaluate the echogenicity of the renal cortex in clinically healthy rabbits. Fourty-two clinically normal and with no history of renal disease rabbits were used. The each rabbit was investigated by complete blood count, urinalysis and renal biopsy. Renal ultrasonography was performed with a 6.5 MHz probe. For each image, three equally sized regions of interest was detected within the renal cortex. The mean pixel intensity was determined using an 8-bit grayscale, with 256 colour of grey colours. Qualitative echogenicity was evaluated by two observers. Observer 1 evaluated as an isoechoic (36/42) and hyperechoic (6/42). Observer 2 evaluated as an isoechoic (35/42) and hyperechoic (7/42). Quantitatively, the mean pixel intensities analysed for the renal cortex was 59.2±2.23 (range: 28-91). The result of this study indicates that analysis of digitized renal cortical ultrasonographic images from rabbits using the histogram technique can be used to quantitatively determine echogenicity.

    Yeni Zelanda Tavşanı’nda (Oryctolagus cuniculus) corpus ciliare’nin morfometrik olarak incelenmesi
    (2009) Orhan, İ. Önder; Oto, Çağdaş; Karakurum, Emine; Ekim, Okan
    Bu morfometrik çalışma ile Yeni Zelanda Tavşanı’nda corpus ciliare’de yer alan corona ciliaris, processus ciliares ve plicae ciliares morfometrik olarak incelendi. Araştırmada 20 adet ergin Yeni Zelanda Tavşanı’nın bulbus oculi’leri kullanıldı. Corona ciliaris’in genişliği, stereomikroskop kullanılarak ölçüldü. Yapılan sayımda plicae ciliares sayısının 301.07± 2.36, processus ciliares sayısının 131.58 ± 2 adet olduğu belirlendi. Sağ ve sol göz arasındaki sayısal farklılıklar istatistiksel açıdan önemsiz bulundu. Bulbus oculi’nin ortalama dorso-ventral çapının 19.23 mm, temporo-nasal çapının 19.69 mm, cornea’nın ortalama dorso-ventral çapının 14.28 mm, temporo-nasal çapının 14.50 mm, pupilla’nın ortalama dorso-ventral çapının 7.48 mm, temporo-nasal çapının 7.19 mm, corona ciliaris’in ortalama dorso-ventral çapının 15.94 mm, temporo-nasal çapının 15.84 mm olduğu saptandı. In this morphometric study, the ciliary ring, ciliary processes and ciliary plicae which reside in the ciliary body, were examined in New Zealand Rabbit. Both sides of the eyeballs of 20 adult New Zealand Rabbits were used. The width of ciliary ring were measured with calibers using stereomicroscope. In counting, number of ciliary plicae was 301.07± 2.36 number of ciliary process was 131.58 ± 2. Quantitative distinctions between right and left eyeballs were no account in statistical. The average dorsoventral diameter of eyeball was 19.23 mm, temporo-nasal diameter of eyeball was 19.69 mm, the average dorso-ventral diameter of cornea was 14.28 mm, temporo-nasal diameter of cornea 14.50 mm, the average dorso-ventral diameter of pupil was 7.48 mm, temporo-nasal diameter of pupil was 7.19 mm, the average dorso-ventral diameter of ciliary ring was 15.94 mm, temporo-nasal diameter of ciliary ring was 15.84 mm.
