Given the physiological significance and the need for further physiological and morphological knowledge of the adrenal glands, the objectives of the current study were to compare morphometric data between the right and left adrenals of male squirrels and hamsters. The study was conducted on five squirrel males and five hamster males. The glands in both animals were removed and fixed in neutral formalin solution. It was found that the squirrel contains two brown-colored right and left adrenal glands connected anteriorly and medially to each cranial pole of the kidney, and the right adrenal gland had a longitudinal shape, while the left gland had an oval shape. Hamsters had two pairs of brown adrenal glands located anteriorly attached to each kidney's cranial pole. The right adrenal gland was round in shape, while the left was oval. The statistical results showed a significant difference between the left and right suitable adrenal glands in both animals, as well as a significant difference between the squirrel gland and the hamster gland, where it was found that the right and left squirrel glands are larger more significant, heavier, longer and thicker than the adrenal gland in hamsters after the following measures were adopted: weight, length, thickness, width, and size.

“…The trabeculae form an arching system, where the limbs of the arches divide the units of the glomerulosa into groups that exhibit significant variations in terms of number and size. This histological observation communicates with the observations made by Sheikhian et al (2015) in their study on guinea pig and hamster .…”

The adrenal glands, responsible for regulating important body functions. This study aimed to examine the structure of the adrenal cortex in 15 healthy she-camels. The camels were divided into three groups based on their age: immature 1-2, mature 3-7, and senile up to 12 years which are not equally divided. Camel adrenal glands are enveloped by a dense network of collagen fibers, forming a unique capsule. This capsule comprised an outer fibrous layer and an inner cellular layer. Notably, connective tissue trabeculae originating from the inner side of the capsule invaded the gland's cortical parenchyma, giving the glomerulosa a distinctive arrangement. This arching system was prominent in mature and senile camels but absent in the immature ones, where eosinophilic cells formed clusters resembling follicles. Hematoxylin and Eosin (H&E) staining was used for general tissue visualization, Masson's trichrome (MTC) staining for collagen fiber, and orcein staining for elastic fiber visualization. Immunohistochemical analysis using caspase3 as an apoptotic marker and proliferating cell nuclear antigen (PCNA) as a marker for cell proliferation shed light on cellular behavior. The immunohistochemical staining revealed strong positive nuclear reactions of PCNA in immature and senile camels, respectively, and weak responses in mature camels. Additionally, caspase 3 exhibited cytoplasmic and nuclear reactivity, transitioning from weak positive in mature camels to strong positive in both immature and senile stages. In conclusion, our study unraveled interesting similarities and distinctive features of camel adrenal glands, providing insights into their architecture.

“…These cells also appear as pale brown after fixation with potassium dichromate (Figure 3). Similar results were reported in the medulla of guinea pigs and vizcacha, in which the medulla composed of ovoid group of cells (chromaffin cells) that arranged in irregular cords separated by blood sinusoid (6,16). These cells also appeared as light blue with Methylene-Eosin staining (Figure 4).…”

The adrenal glands are endocrine glands that produce a diversity of hormones comprising of adrenaline, the aldosterone and cortisol. The present study aimed at investigation of the histomorphometric features of chromaffin cells. There were two types of chromaffin cells. In squirrel, the first type was columnar in shape and brownish in color contained spherical nucleus located at the base of cells, which represented the epinephrine secreting cells, and the second type was polygonal in shape and light brownish in color contained spherical nucleus located in the center of cells, which represented the norepinephrine secreting cells. The adrenal medulla of hamster consists almost entirely of columnar or polyhedral chromaffin cells forming clusters and anastomosing cords separated by sinusoids, giving a strong reaction with methylene eosin stain more than that seen in squirrel. The statistical analysis showed that the means diameter of epinephrine cells and norepinephrine cells in the right adrenal gland in squirrel were lesser than those of hamster significantly at P<0.05, but in the left adrenal gland in squirrel the means were greater than those of hamster significantly at P<0.05. In conclusion, the present findings showed the reaction of chromaffin cells of hamster with methylene –eosin stain to be stronger than with hematoxylin-eosin stain, while the opposite was true in case of the squirrel.
