Item Metadata only Blood vessels of the human interventricular septum : the study of plastinated heart slices(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Prapatsorn Piw-ngarm; Boonsirm Withyachumnarnkul; Reon Somana; Sanjai Sangvichientheir interventricular vessels lying close to the right ventricle. Moreover, the large arteries lying in the middle or a little to the right ventricle while the small arteries lie close to the right ventricle. When compared to the free wall arteries, the septal wallItem Metadata only Types of vascular wall as related to vasa vasorum in common tree shrew (tupaia glis)(Mahidol University.

The IC also anastomoses with a subcapsular capillary plexus. In addition, a pattern of blood vessels resembling portal-like intraganglionic microcirculation could not be demonstrated in the SCG of both rat and tree shrew.

After plunging into the gland, the arteries divided into smaller branches being interlobular, intralobular, and follicular arteries (afferent vessels), respectively. The basket-like... network were also observed. Blood from the follicular capillaries either drained into follicular veins (efferent vessels) or abruptly drained into interlobular veins before proceeding to intralobular and interlobular veins, respectively. The interlobularItem Metadata only Scanning electron microscopic stydy on pineal vascularization of common tree shrew (Tupaia glis)(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Panjit Chunhabundit; Reon Somana; Thyon ChentanezItem Metadata only Microvascularization of the midbrain in common tree shrew (Tupaia glis)(Mahidol University. Mahidol University Library and Knowledge Center, 2000) Churairat Duangchan; Reon Somana; Boonsirm Withyachumnarnkul; Wisuit PradidarcheepThe study of the midbrain in the common tree shrew (Tupaia glis) with vascular corrosion cast under a stereomicroscope and a scanning electron microscope (SEM) reveals that the midbrain is supplied by the branches of the vertebrobasilar system which are the basilar artery bifurcation, posterior cerebral, superior cerebellar, medial posterior choroidal and collicular arteries. They give off the penetrating arteries which radially course into the internal part of the midbrain and reach the cerebral aqueduct. This is the centripetal arrangement. The internal artery of the midbrain is divided into anteromedial, anterolateral, lateral and posterior groups according to the points of entry and territories that they supply. The penetrating arterioles terminate as capillary networks. The degree of capillary density in the midbrain is closely related the density of the nerve cells that accumulate in the areas of the midbrain nuclei. Less vascularity is obvious in the areas occupied by nerve fibers. The arterial anastomoses could be observed in the perimesencephalic or external part of the midbrain. The midbrain capillaries are without fenestrations. The venous drainage in the midbrain could be divided into three groups. The venous blood from the area ventral to the cerebral aqueduct drains into the tributaries of the veins of the anterior or petrosal group. The posterior group collects the venous blood from the collicular vein and the superficial vein of the quadrigeminal plate. The superior or galenic group receives the blood from the thalamocollicular, the lateral and dorsal aqueductal veins that empty the venous blood into the great cerebral vein of Galen, rectus sinus. Finally, the venous blood from both rectus and superior petrosal sinuses drain mainly into the external jugular vein and some into the internal jugular vein.Item Metadata only Microangioarchitecture of seminal vesicle and prostate gland in common tree shrew (Tupaia glis)(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Koumkrit Pisetpaisan; Reon Somana; Panjit Chunhabundit; Wisuit Pradidarcheep; Wichai Ekataksinurethra. These vessels eventually branch out into smaller vessels, at the intermediate section of the duct most of which continue to the distal part (the glandular acini) where they supply tilt distal region of the prostatic duct and the glandular portion.Item Metadata only The pancreatic angioarchitectural changes in alloxan induced-diabetic rat(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Sirinush Bamroongwong; Reon Somana; Boonsirm Withyachumnarnkul; Vijittra Leardkamolkarnof golgi bodies with marked degranulation are also evident. Noteworthy, the large continuous capillary or collecting venule as well as a reduplication of basement membrane of the dilated vessels in ischemic area of the islet are observed. However, A and D... cells are apparently unharm. In the pancreatic acini of diabetic rats, the varying sizes of dilated blood vessels are observed with light microscopy.

Mahidol University Library and Knowledge Center, 2024) Supitta Selavattanakul; Chaitip Wanichanon; Prasert Sobhon; Boonsirm Withyachumnarnkuland colon. Degeneration of the epithelial cells in the intestines were not observed. In addition, amyloid deposits were found in the extracellular space and in the wall of blood vessels in the liver, spleen, and mesenteric lymph nodes. Following granuloma... formation and amyloid deposition, collateral blood vessels, dilatation of sinusoids and atrophy of hepatocytes were observed in the liver. The splenic cords were compressed, and their lymphoid cells were more closely packed.
