Abstract

Metode konvensional isolasi sel endotel pembuluh darah otak (EPDO) masih tergolong sulit, sehingga upaya mendapatkan populasi murni sel ini adalah tantangan. Pada penelitian ini dilakukan isolasi endotel dari tikus Wistar dan mencit C57/Bl6, berdasarkan protokol the care and use of laboratory animals, Universitas Gunma, Jepang. Modifikasi metode isolasi adalah menggunakan gradasi bovine serum albumin (BSA), bukan Dextran-70 yang umumnya dipakai, untuk memisahkan sel EPDO yang bersatu menjadi sel EPDO tunggal. Penelitian ini dilakukan di laboratorium sel kultur, Universitas Padjadjaran bekerjasama dengan Universitas Gunma, Jepang, Januari 2008?Juni 2009. Uji hasil isolasi dan karakteristik sel EPDO dilakukan dengan teknik imunofloresen. Ekspresi tight junction ZO-1, menunjukkan sel EPDO membentuk selapis sel utuh, rapat, tidak bertumpuk dan kompak, sesuai dengan karakteristik dinding EPDO. Fenotip sel EPDO dikonfirmasi dengan acethylated LDL, faktor von Willebrand dan CD31. Penghancuran kapiler dengan collagenase/dispase masih menghasilkan populasi sel yang terkontaminasi perisit. Kontaminasi dimurnikan dengan menggunakan puromycin, tingkat pemurnian sel EPDO mencapai 98,3%. Simpulan, teknik modifikasi berhasil mengisolasi sel EPDO tikus dan mencit, tanpa melakukan intervensi genetik. Puromycin dapat digunakan untuk memurnikan sel EPDO.

In this study, we isolated BMVECs from Wistar rat and C57/Bl6 mouse from Japan SLC. All procedures performed according to guidelines for the care and use of laboratory animals of Gunma University, Japan. The modification of isolation method was using bovine serum albumin (BSA) gradation, not Dextran-70 in which generally used, to separate clusters of BMVECs into single cell. This study was done at Universitas Padjadjaran, in colaboration with Gunma University, Japan, January 2008?June 2009. Further,characteristic and purification results were proven by imunofluorescene staining. The results showed that staining of tight junction, ZO-1, formed a monolayer, tightly packed, non-overlapping and contact-inhibited BMVECs, as expected for a vessel wall endothelial. ECs phenotype confirmed by acethylated LDL, von Willebrand and CD31. The digestion of capillaries generated contaminating pericytes. Contamination was purified using puromycin and the results considered satisfactory (98.3%). In conclusion, our modification procedure allows the isolation of primary rat and mouse BMVECs, which form an endothelial-like monolayer in few days. Puromycin can be used for purification of primary rat and mouse BMVECs. [MKB. 2010;42(4):161?8].Key words: Blood brain barrier, isolation modified-method of mouse-BMVECs, purification methods DOI: http://dx.doi.org/10.15395/mkb.v42n4.30

Abstract

Introduction: Pleural effusion (PE) is characterized by reduced lung distensibility and expansion, resulting in decreased lung volume. Pleural effusion patients often experience respiratory symptoms that impair quality of life (QoL) and daily activities. Pulmonary rehabilitation (PR) has been developed to enhance functional capacity, alleviate symptoms, improve exercise tolerance, and reduce health service utilization. However, data on the specific implementation and benefits of PR in PE patients are limited. Methods: This literature review synthesized data from a search using Public Medline (PubMed), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Google Scholar databases. The search was based on keywords relevant to study objectives and comprised various article types, ranging from review papers to original research. Articles with titles and abstracts relevant to the study objectives proceeded to a full-text evaluation. Results: A narrative review discussing PE from pathology to rehabilitation management was formulated from 12 articles that elucidated various aspects of functional impairment in PE patients and 24 sources that discussed rehabilitation management. Conclusion: Rehabilitation interventions, especially mobilization programs and lung expansion techniques, have shown effectiveness in improving pulmonary function and functional activities. Data regarding the role of inspiratory muscle training and aerobic exercise specific to PE remain limited. Given the functional impairments associated with PE, both before and after the removal of pleural fluid, PR programs are crucial in improving symptoms, pulmonary function, and overall functional ability in these patients.

Abstract

Objective: To study the transformation point of meningeal and periosteal dural at the porus of internal acoustic canal (IAC) in order to verify the different thickness of meningeal and periosteal dura in vestibular schwannomas (VS). Methods: Three IAC cadaver specimens and ten samples of VS patients from porus were obtained and analyzed. Samples were stained by using Masson trichrome technique after cutting in 6 micron of thickness. The samples were then observed under light microscopes to understand the meninges pattern in the IAC. Results: The meningeal dura is becoming thin at the porus and disappears at the meatal portion to form epineurium. However, the periosteal dura is lining continuously to the fundus. In VS, the meningeal dura becomes thick and forms a pseudo-capsule in the middle of meatus, known as perineurium. The residual nerve filament was compressed by the tumor parenchyma. Between the tumor and nerve interface, three or more perineureal layers are seen. The perineurium in the cisternal portion was consistently loose and forms the tumor and arachnoid nerve interface. Almost all the nerve filaments are displaced to the tumor periphery near the pseudocapsule. In contrast, the periosteal dural of VS is becoming thin and disappear nearby the middle of meatal portion. This changing site establishes “meningo-periosteal ring” of VS because of the encircling nearby the porus. Conclusions: In IAC, the meningeal dural becomes thin. The periosteal dura is lining continuously to the fundus. In VS, the meningeal dura becomes thick, joins perineurium and forms pesudocapsule near the porus, but the periosteal dura disappeared. This changing point is called meningo-periosteal ring.     Keywords: Meningeal,  periosteal, porus, vestibular schwannomasDOI: 10.15850/ijihs.v1n1.104
