Histomorphological and stereological study on the adrenal glands of adult female guinea fowl ( Numida meleagris )

AbstractAdrenal gland is one of the most important glands of the endocrine system, located in the anterior pole of kidney and secretes important hormones that play roles in carbohydrate, water and electrolyte metabolism and maintain the blood pressure in birds. Since the available information regarding the histology and stereology of adrenal gland are limited, this study was conducted to determine the histomorphology and stereology of this gland. For this purpose, 8 adult helmeted guinea fowls were killed humanely and used. Their adrenals were removed and immersed in buffer formalin 10%. Then, tissue sections were prepared; staining with hematoxylin and eosin and green Masson ’s trichrome and studied. Histological results showed that adrenal was composed of three layers: the subcapsular, peripheral and central layers. The subcapsular layer consisted of a thin layer of medullary cells while peripheral layer consisted of dominated cortical and small groups of medullary c ells and finally the central layer consisted of cortical and dominant medullary cells. Sinusoids and ganglion cells were observed in all areas of adrenal. With the aid of stereological technique, the percentage of different parts of the adrenal was determined. In the right adrenal, cortex, medulla, capsule and sinusoids were 69/34%, 20/83%, 5% and 4/83% respectively and in the left adrenal, cortex, medulla, capsule and sinusoids were 71/16%, 20/16%, 4/68% and 4% respectively. Statistical analysis showed t...

ConclusionTaken together, our results reveal that retinal thinning is present in young adults with PSDs, but in comparison to the literature we found more prominent changes in both GC-IPL and macular volume/thickness, than in RNFL. Our findings may reflect synaptic loss and neuronal atrophy in non-acute young patients with psychosis.

S. eriocheiris invaded the hemocytes in the early stage, then invaded nerve tissue and caused typically paroxysmal tremors of pereiopod in the late stage of infection. The purpose of this study was to detect the infection mechanism of hemocytes in the e...

In the mammalian cochlea, resident macrophages settle in the spiral ligament, spiral ganglion, and stria vascularis, even at the steady state. Resident macrophages in the cochlea are believed to maintain homeostasis in the inner ear and become active, as part of the front line defense, following inner ear damage. However, the exact roles of cochlear resident macrophages require further clarification. Colony stimulating factor-1 (Csf1) signaling regulates survival, proliferation, and differentiation of resident macrophages and appears to be essential for resident macrophages in the inner ear. To examine the roles of Csf1 si...

We report that receptor-ribosome coupling is employed by multiple guidance cue receptors and this interaction is mRNA-dependent. We find that different receptors associate with distinct sets of mRNAs and RNA-binding proteins. Cue stimulation of growingXenopus retinal ganglion cell axons induces rapid dissociation of ribosomes from receptors and the selective translation of receptor-specific mRNAs. Further, we show that receptor-ribosome dissociation and cue-induced selective translation are inhibited by co-exposure to translation-repressive cues, suggesting a novel mode of signal integration. Our findings reveal receptor-s...
