Title

THE STUDY OF MORPHOGENESIS AND ASCENT OF KIDNEYS IN SANNEN GOAT

Pages

  2275-2280

Abstract

 Kidneys, like most mammalian body organs, start forming and pass Pronephric, Mesonephric and Metanephric stages along the crest of the urinary tract until final growth. Although KIDNEYs are at first, in close association with gonads in both sexes, ascend and reach their final location, on the contrary of gonads. The aim of present experiment was to reveal DEVELOPMENTal stages and sites in which KIDNEY pass during ascent in embryonic and fetal periods in SANNEN GOAT. For this purpose, 106 goat fetuses in various sizes where collected from yazd slaughter houses randomly, and due to affection of different factors on fetal growth which makes accurate age estimation difficult, CRL parameter was utilized. Samples were divided into 10 groups from CRL=1cm to CRL=31.5cm. The result showed that in samples with CRL=14.5-16.7cm, cranial part of mesonephrose was degenerated. The latter phenomenon had reached to pick point in CRL=26cm. In this case, primitive metanephrose (definitive KIDNEY), as a cell mass well seen at terminal part of mesonephric duct. In fetuses with CRL=31cm, metanephrose was seen in a developed state under stereomicroscope. so, it could be concluded that final stages of DEVELOPMENT of metanephrose takes place from CRL=26cm to CRL=30.5cm in SANNEN GOAT. In fetuses with CRL=31cm KIDNEY shave gained bean shape, which is normal in goat. In fetuses with CRL=31.5cm (full term), the left KIDNEY was ascended from previous location that's mean, vertebral limit L4-S3 to L2-L5, but in right KIDNEY from L3-S2 to L1-L4. It was also concluded that longitudinal length, transverse, and thickness of KIDNEY correlate with increasing whole body of fetus and also weight increase of KIDNEY correlates with increase of fetus growth itself.
