SOME TOPOGRAPHICAL AND HISTOLOGICAL STUDIES OF THYROID AND PARATHYROD GLANDS OF MOORHEN (Gallinula c. chloropus)

The thyroid gland of Moorhen has two separated lobes. These lobes were located in the throracic inlet and receive blood supply from the cranial, middle and caudal thyroid arteries. The histological organization of the thyroid gland in Moorhen is surrounded by a distinct connective tissue capsule and the parenchymal cells were arranged into colloid filled follicles enmeshed in the highly vascular interstitial connective tissue. The bilaterally paired, round to oval, parathyroid glands in Moorhen were located intrathoracically near or close to the caudal pole of the thyroid glands. They receive blood by short branches from caudal thyroid artery and small branch from the common carotid artery. The parathyroid glands in Moorhen have a thin connective tissue capsule. Its parenchymal cells were arranged into an irregular, anastomosing cords of chief cells. No oxyphil cells were found in the parathyroid glands of Moorhen.

SUBUNGUAL GLOMUS TUMOUR: THE ENIGMATIC CAUSE OF CHRONIC PAINFUL FINGER PULP - A CASE REPORT

Glomus tumour, also referred to as Barré–Masson syndrome is an enigmatic, rare, painful tumour that is that represents a proliferation of the normal capsular-neural glomus apparatus. These are rare hamartomas that arise from the traditional glomus apparatus, located in subcutaneous tissue These are benign soft tissue neoplasms presenting usually within the second to fourth decade of life, originating from the glomus body. It accounts for 1-5% of all upper limb soft tissue tumors . It's a component of the dermis layer of the [1] skin, involved in thermoregulation. It structurally consists of an arterio-venous shunt which is surrounded by a connective tissue capsule and is found in increased amounts in the ngers and toes.

Morphological and Histological Study of the Pineal Gland in local breed Goats (Capra hircus)

The current study was carried out to investigate both morphological and histochemical features of pineal gland in goat. Eight samples of pineal glands were used. The morphological study was involved the position, relation, weight, length and width of the glands. The tissue sections were prepared for paraffin embedding technique and stained with Hematoxyline & Eosin, Masson trichrom, Alizarin and PAS stains. The morphological result of pineal showed slightly irregular round-spherical shaped, grayish white in color. It located in the same mid-depression between the thalami body and two colliculi. The weight of gland was 0.478±0.02 mg and measured 2.10±0.06mm in length and 2.52±0.15mm in width. Histologically, the pineal gland has enveloped by a smooth thin layer of loose connective tissue capsule showed less trabiculae that carried the blood vessels into gland and the trabiculae have composed of fine collagen fibers. The glandular parenchyma showed marked lobular pattern of division with marked lighter central region which showed less cellular population. The glandular lobule consisted of three types of cells; Type I pinealocytes or dark pinealocytes, the second type was the less populated type II pinealocytes or light pinealocytes and the third type was the glial cell. The Alizarin stain was revealed multiple of variable size calcium patches within collagen fibers. The cytoplasmic contents of both pinealocytes types I & II showed no glycogen granules.

Chronic Expansive Retroperitoneal Hematoma

Chronic expansive retroperitoneal hematoma is a hematoma that grows progressively sometime after the original trauma. It can appear in different locations. The mechanism of onset is unclear, but experimental evidence favours an inflammatory cause. For diagnostic imaging, magnetic resonance imaging is more useful than computed tomography (CT). However, it is difficult to differentiate it from other soft tissue tumors, sarcomas, actinomycosis or inflammatory pseudotumors, due to the uneven central uptake. Histopathological analysis of the lesion usually shows a dense fibrous tissue capsule containing numerous old clots without finding clear atypia or signs suggestive of malignancy. The treatment of choice is complete resection of the lesion (including the capsule), as incomplete treatments (such as drainage or curettage of the hematoma contents) may cause recurrence.

Implants and bone technology with the use of doped calcium carbonate phosphates

The possibility of obtaining an alloplastic biomaterial for the implant based on doped calcium carbonate-phosphates and polycaprolactone is studied. Nanocrystalline calcium carbonate-phosphate doped with cations of iron, magnesium, potassium, zinc, manganese, and silicon intended for bone repair by drug delivery is investigated. Histological studies have revealed that samples after 60 days in a living organism are covered by a connective tissue capsule. The formation of blood vessels and nerve endings is observed in the capsule.

Morphogenesis lymph node of domestic pig

The visceral and somatic lymph nodes of a pig of domestic 1-120 day old were examined. Found that the lymph nodes have a common connective tissue capsule and different levels of fusion of individual subunits. In the center of each subunit, the capsule forms invaginations of the capsular trabecula, dividing the parenchyma of each structural unit into «Ʊ»-shaped structures, fused with lateral and lower parts. The number and degree of fusion of subunits is different and depends on the age of the animals and the location of the lymph node. The greatest degree of fusion of individual units of the lymph node was found in the superficial cervical and axillary I ribs. In the mandibular, superficial parotid and superficial inguinal lymph nodes, the segments are clearly contoured already in newborn piglets. Segments are predominantly bean-spherical in shape with a wide base. The fusion of the segments occurs in their central part, and on the surface the gates of the subunits are clearly contoured in the form of numerous depressions. In the visceral lymph nodes, the portal and splenic lymph nodes have the smallest segmentation, and the gastric, tracheobronchial, and iliocolic lymph nodes are the largest. The number of segments varies from two in newborn piglets to five in 120-day-old pigs. The variability of the morphometric parameters of the lymph nodes of a domestic pig is due to a different number of afferent lymphatic vessels, and, accordingly, to different scales of the lymphatic basins. Thus, the lymph nodes of the domestic pig are complexes of subunits fused to varying degrees. Somatic lymph nodes are highly segmented. The degree of consolidation of subunits in the visceral lymph nodes is less pronounced. Linear measurements of organs vary depending on the age of the animals, gradually increasing up to 120 days with a tendency for these indicators to prevail in the somatic lymph nodes. Key words: domestic pig, lymph node, subunit, topography, morphometry

Florid osseous dysplasia, lesi radiopak bilateral pada radiograf panoramik

Objectives: The aim of this report is to present a case of florid osseous dysplasia and understand its characteristics from panoramic radiography. Case Report: A 47-years-old female patient came to the oral and maxillofacial radiology department at Dental and Oral Hospital of Universitas Padjadjaran to take panoramic radiography. Patient’s chief complaints were pain on tooth 46 after being extracted about 4 days ago with numbness on the extraction area. Panoramic radiograph showed radioopaque lesions in the extraction area surrounded by a thin radiolucent area. In the periapical region of tooth 36 and 47 showed the same radiopaque image as tooth 46. The radiodiagnostic suspect of the lesions was bilateral florid osseous dysplasia in the posterior region of the mandible. Conclusion: The images of florid osseous dysplasia from panoramic radiography are radioopaque, well-defined, sclerotic border, and having soft tissue capsule when the lesion is immature condition. The most common condition of FOD affect both upper and lower jaw, but if the lesion only occur in one jaw, the lesion commonly happen in mandible with exact location is more posterior than canine teeth.

Bilateral adrenal-renal fusion: A radiological diagnosis

In normal anatomy, the kidneys and adrenal glands are contained within the renal fascia and separated by a connective tissue capsule derived from mesenchymal tissue. Incomplete encapsulation can occur during embryonic development, resulting in adrenal-renal fusion. The true incidence of this developmental anomaly is unknown, as it has primarily been described in the literature following incidental detection on surgical or histological examination. We report the first documented case of bilateral adrenal-renal fusion, diagnosed radiologically.

Expression of cocaine- and amphetamine-regulated transcript in the pancreas of the European bison

Cocaine- and amphetamine-regulated transcript (CART) is a recently discovered neuropeptide thought to mainly act in most laboratory mammals and humans as anorexigenic factor. The expression of CART in wild living animals is barely known. In the present study immunohistochemical stainings were applied to identify CART-immunoreactive (IR) structures in the pancreas of European bison. Antibodies against neuronal marker Hu C/D were used to visualize intrapancreatic neurons. The expression of CART was detected in approx. 75% of Hu C/D-IR intrapancreatic neurons which may thus also act as interneurons. Additionally, in most intrapancreatic ganglia single CART-IR non-varicose nerve fibers running between neurons were found. Pancreatic blood vessels as well as intralobular ducts were sparsely innervated with CART-IR nerve fibers. Moderately numerous CART-IR nerve terminals were found to innervate the pancreatic endocrine and exocrine tissue. None of islet endocrine cells showed the expression of CART. No presence of CART-IR neuronal elements were found in external connective tissue capsule and septa penetrating inside to the organ. Our study is the first to outline the presence of some differences in CART-ergic innervation pattern of the pancreas between domestic and wild mammals. The lack of CART-IR endocrine islet cells in the pancreas of European bison is an interesting finding, nevertheless its significance is largely unknown at the moment and needs to be further investigated.

The effectiveness of the reparative processes stimulation of the platelet-rich plasma in case of the abdominal wall endoprosthetics

Relevance. The number of ventral hernias recurrence after abdominal wall endoprosthetics with the lightweight endoprosthesis is 8-10%. The purpose of the research is to study the morphological changes of the connective tissue, surrounding a lightweight polypropylene endoprosthesis, at the early stages of implantation at the use of platelet-rich autoplasma. Materials and methods. The results of experimental research of the course of wound process in the abdominal wall tissues during the implantation of the lightweight polypropylene prosthesis on 50 Chinchilla rabbits divided into 2 groups of 25 animal units each have been analyzed. Subaponeurotic implantation of the prosthesis was carried out in the first group of animals. In the second group, the platelet-rich autoplasma was twice introduced after the implantation of the prosthesis during surgery and on the third day of the postoperative period at the rate of 0,5 ml plasma per 1 cm2 of the endoprosthesis. The animals were taken away from the experiment on the 3rd, 7th, 10th, 14th and 21st day. Morphometric and histological study of reactive changes of tissue surrounding the implanted endoprosthesis was carried out. Results and its discussion. In the animals of the second group, the inflammatory response to prosthesis implantation was 1,3 times lower on the third day, 1,2 times lower on the 7th day, and 1,1 times lower on the 10th day, than in the first group. Fibroblastic response, on the contrary, has increased into 1,2 times on the third day, into 1,14 during the 7th day and into 1,18 during the 14th day after the introduction of autoplasma. The thickness of the connective tissue capsule in the second group was 1,57 times higher than in the first group on the 21st day of the experiment. At this time, in the first group, the immature connective tissue capsule has been represented by the loose collagen fibers and fibroblastic cells without separation into the layers. In the second group, a dense connective tissue frame has been formed by the mature collagen fibers arranged compactly and in parallel to each other. The layer-by-layer structure of the capsule is well expressed: the inner layer consists of the fibroblastic cells, and the outer layer consists of the mature collagen fibers. Conclusion. The use of platelet-rich plasma to stimulate reparative processes in the implantation of the lightweight polypropylene prosthesis in the abdominal wall is pathogenetically justified and effective.
