Mahidol University Library and Knowledge Center, 2024) Pongsak Rattanachaikunsopon; Reon Somana; Prasert Sobhon; Kanok Pavasuthipaisitto the deep surface of the thyroid gland before joining jugular vein. 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, 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 Effect of Ginsenoside RE on SKCa currents in human coronary artery endothelial cells(Mahidol University. Mahidol University Library and Knowledge Center, 2011) Suporn Sukrittanon; Wattana B. WatanapaEndothelial cells are important in regulating coronary circulation, by secreting vasodilators and/or vasoconstrictors. Ginsenoside Re (Re), an active component in ginseng, was reported to increase NO secretion from human umbilical vein endothelial cells. In other cell types, this compound was found to increase K+ current or Ca2+-sensitive K+ (KCa) currents, leading to nitric oxide synthase (NOS) stimulation, increased NO secretion and vasodilation. Re, therefore, may increase KCa activity in human coronary artery endothelial cells (HCAECs). Cultured HCAECs exposed to different concentrations of Re were studied using the whole-cell patch clamp technique. Specific blockers of small- and intermediate-conductance KCa (SKCa and IKCa), non-selective cation (NSC) and inward-rectifier potassium (Kir) channels were employed to study or inhibit individual currents. All currents were reported as mean ± SEM. Re dose-dependently increased outward currents (EC50 = 408.90 + 1.59) nM; P < 0.05). 1 μM Re could significantly increase outward currents by 28.93 ± 7.54 % when the NSC channel was blocked by La3+, but failed when the SKCa channel was inhibited by apamin. When NSC, inward rectifier, intermediate- and highconductance KCa channels were simultaneously blocked (with La3+, Ba2+, clotrimazole and TEA), Re could still increase outward currents significantly (35.49 ± 4.22 %); this effect was again abolished by apamin. These results indicate that Re increased HCAEC outward currents by opening SKCa channels. Therefore, ginsenoside Re may also cause coronary vasodilation in humans, adding to the benefits of ginseng, with a promising future in the protection and/or treatment against coronary artery disease and other cardiovascular conditions.
