Abstract

Background: Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor in adultswith dismal prognosis due to the unavailability of an effective therapy. Up to now, there had been no definitive studies published on EGFR inhibition therapy as a chemosensitizer for GBM therapy using Temozolomide (TMZ). This study aims to reveal the most effective method and timing to administer TMZ anti EGFR targeted therapy which causes maximal DNA damage on GBM cells. Methods: Various regimens of anti EGFR monoclonal antibody Nimotuzumab (NMZ) was administered in different combinations with TMZ, performed on U87MG MGMT(+) EGFR(+) cells. The effectiveness of the combinations were evaluated by measuring yH2AX levels which reflects the degree of DNA damage. One-way Anova and LSD tests were performed to determine the effects of each treatment with p

Abstract

Background: Brain injury often occurs not only primary brain injury, but often also occur secondary brain injury. Inflammation is a process that occurs immediately after trauma characterized by activation of the mediator substance. TNF-? is a major cytokinee involved in the inflammatory processes that have adverse effects if the serum level are excessive. There needs to be a balance of the inflammatory process in the brain injury so things that harm does not occur. As anti-inflammatory IL- 10 plays an important role in maintaining the balance. The objective of this study is to determine the effect of IL-10 intervention as an anti -inflammatory will decrease the serum level of TNF-? in traumatic brain injury. Material And Method: Experimental Study in the Rattus Wistar rats, post test control group design, male, aged 3-4 months, with body weight (BW) 300-400g, were obtained from the Laboratory Animal Faculty of Medicine, University of Hasanuddin as much as 24 tails, which is the result of breeding. Subjects were divided into four groups, each group of six rats, treated with controlled cortical impact model (Feeney’s weight-drop) of traumatic brain injury. Blood taken with capillary tube in retro-orbita plexus or sinus.This study has approved by ethical clearance for research. Results: Levels of TNF-? group of rats 1 hour post-trauma without administration of recombinant IL-10 (28.58 ± 7.28) pg / mL; was significantly higher (p
