Objective
Information regarding the development of the enteric nervous system (ENS) is important for understanding the functional abnormalities of the gut. Because fertilized chicken eggs provide easy access to embryos, chicken models have been widely used to study embryonic development of myenteric plexus; however, no study has been focused on the...
The structure of the nephron in adult soft-shelled turtles (Pelodiscus sinensis) was studied by light microscopy, transmission and scanning electron microscopy. The kidney contained 5-6 renal lobes. Nephrons of P. sinensis are composed of a renal corpuscle (RC) and of a renal tubule that appears divided morphologically into five distinct segments:...
The present work describes the distribution of S-100 protein in the intestinal tract of a Chinese soft-shelled turtle specimen (Pelodiscus sinensis). S-100 protein positive cells were located in the intestinal tract, from the proximal small to distal large intestine. S-100 protein positive dendritic cells had irregular shape and were positive in bo...
Morphological characteristics of the kidneys in the two-humped camels were investigated using the anatomical and histological methods. The 2 kidneys in the camel contributed about 0.6% of the body weight. The ratio of thickness of the renal medulla to the cortex was 4:1, which indicated that Henle’s loops in camel’s kidneys were very long. In corte...
We investigated the structure of the soft-shelled turtle, Pelodiseus sinensi, spleen and demonstrated that there were several microanatomical peculiarities by light and transmission electron microscopy. In the spleen, the white pulp of the spleen was composed of two compartments, the periarteriolar lymphatic sheath (PALS) and periellipsoidal lympha...
Spermiogenesis in the soft-shelled turtle, Pelodiscus sinensis, was examined by transmission electron microscopy. The process includes nuclear elongation, chromatin condensation, acrosomal and flagellar development, and elimination of excess cytoplasm. In stage I, the proacrosomal vesicle occurs next to a shallow fossa of the nucleus, and a dense a...

... To analyze the spatial distribution of the 3D neurovascular network of gray matter in the thoracolumbar spinal cord, the neuron and vasculature in a 225 lm 9 150 lm 9 225 lm volume from the VH, DH, and IGM (lamina VII) were selected from each mouse for quantitative evaluation. The 3D-rendered data were analyzed with Image-Pro Analyzer 3D (version 7.0, Media Cybernetics, Inc., Bethesda, USA) to obtain quantitative data for the neural and vascular structures [31]. ...
... The water conservation ability of mammalian kidney has been estimated from the size of the renal pelvis (Abdalla, 2020), the value of the relative medullary thickness (Al-kahtani et al., 2004), the extent of the renal crest (Kriz and Kaissling, 2008) and the ratio of the medullary to cortical thickness (Xu et al., 2009). In the present study, the renal pelvis was small and not as elaborate as that of the dromedary camel, as reported by Abdalla (2020). ...
... DCs had not been characterized in the Agnatha and the amphioxus; however, paralogous genes of the MHC complex have been identified in the amphioxus, as well as two populations of lymphocyte-like cells [72]. The common phenotype is characterized by the expression of S100 antigen [73], MHC II, CD8a [74], CD83, CD86, Langerin/CD207 [63], and others, including TLRs, highly conserved molecules [21,75]. ...
... Symposium, which was held virtually due to the COVID-19 pandemic. described as a complex composed of ellipsoid-associated cells, supporting cells, and reticular fibers with outer layers of a periellipsoidal lymphatic sheath (Bao et al., 2009). Turtles display a cellular response to bleeding in which new erythrocytes appear in circulation approximately two days later (Hirschfeld & Gordon, 1965). ...
... Several previous AR studies have evaluated turtle reproductive physiology, especially with regard to gametogenesis and gamete storage. Zhang et al. (2007) evaluated spermiogenesis in Chinese soft-shelled turtles, Pelodiscus (Trionyx) sinensis, using transmission electron microscopy. The study revealed that the process involves multiple steps, including elongation of the nucleus, condensation of chromatin, development of flagella, and elimination of excess cytoplasm (Zhang et al., 2007). ...
