A Morphological Study in Broiler Chick Hearts
(1997) Aydinlioǧlu, A.; Raǧbetli, M.Ç.; Uǧraş, S.; Erdoǧan, E.
The normally developing cardiovascular system of the chicken resembles that of the human. The purpose of the present study is to investigate some macroscopic and microscopic similarities between the chick and the human heart. For this study 20 adult and 10 newborn Broiler chickens were used. The heart and great vessels were routinely fixed in 10% formaldehyde in a phosphate buffer. Five adult and five newborn chicks hearts were embedded in paraffin. All section were examined by light microscopy. The atrioventricular valve of 15 adult chick hearts were examined macroscopically. While some structures previously reported were determined, two different properties of the mural leaf which are chordae tendineae in its posterolateral region anchoring at the right ventricle and its widening from the anterior to posterior commissure was also observed.
The Stereological Ratio of Stromal/Parenchymal Components in Postnatal Prostate Tissue of Rats Prenatally Treated With Diclofenac Sodium
(2013) Kara, M.; Raǧbetli, C.; Koyun, N.; Çölçimen, N.; Raǧbetli, M.Ç.
Since diclofenac sodium extends the pregnancy and affects the fetus, our study aimed to stereologically investigate the components of the rat prostate with prenatally treated with diclofenac sodium. The rats were left overnight to mate. Pregnant animals were kept in a room tempreture with normal light and dark cycles and fed with normal diet. After injections to sham and treated groups for 15 days, 18 male offsprings were housed in three groups (6 placebo; 6 control; 6 treated). The 20 weeks-old animals were perfused and the prostates removed and embedded in paraffin. Tissue sections at 5μm thickness were taken at regular intervals and stained with Hematoxylin-eosin and Masson trichrome. Cavalieri principle was used for volume fractions analysis. Stereological examination revealed 55% acinar epitelium and 45% connective tissue in both control and placebo groups, as well as 60% acinar epitelium and 40% connective tissue in the treated group. Prenatally applied diclofenac sodium did not cause a statistically significant change in the prostate stroma-parenchymal ratio in 20-week old rats compared to the control animals (p>0.05). © 2013 OMU.
