The Change of BDNF Expression in Traumatic Brain Injury After Kaempferia Galanga L. Administration: an Experimental Study

BDNF has potent effects on neural synapses and its pathway affects cell survival and other biological processes. Kaempferia galanga L. has many active substances with antioxidant and anti-inflammatory effects. We analyzes BDNF in four different group of Wistar rats (Ratus novergicus) into Groups A (no trauma & extract), B (with trauma & no extract), C (with trauma and 600 mg/kgbw extract), and D (with trauma and 1200 mg/kgbw extract). Groups B, C, and D are further divided into those who had their BDNF measured on 24- (B24, C24, and D24) and 48-hours. BDNF expression were found to be statistically significant between Group A with both B24 (p = 0,009) and D24 (p = 0,009) on the 24-hour post-trauma decapitation analysis. On the 48 hours after trauma and extract administration, Group B48 (p = 0,002), C48 (p = <0,001), and D48 (p <0,001) were found to be significantly different with Group A. The administration of Kaempferia galanga L. extract can be considered as an option in increasing brain BDNF levels which are neuroprotective. Larger and specific studies are needed to determine the appropriate dose and duration

Expression Malondialdehyde (MDA) of Brain After Injury with the Extract of Kencur (Kaempferia Galanga L): Experimental Study Wistar Rats

Neurological damage in brain injury occurs due to secondary brain injury. Kencur extract has antioxidant potential with total phenolic and flavonoid content including luteolin apigenin and is expected to reduce MDA expression to prevent secondary injury. This study is an experimental laboratory. The treatment of all samples was carried out simultaneously using a post-test-only control group design. Based on the ANOVA test, the significance value of the Kencur extract treatment group was 0.000 (p<0.05) indicating that there was a difference in MDA expression in brain-injured rats without kencur extract with brain-injured rats and given kencur extract. In the 24-hour and 48-hour time groups, a significance value of 0.488 (p> 0.05) showed no significant difference in MDA expression. Then the Kencur extract treatment group with a time group of 0.117 (p> 0.05) showed no significant difference in MDA expression. There was a significant difference in the expression of MDA in brain-injured rats without kencur extract with brain-injured rats and given kencur extract. There were no significant differences in the MDA expression in the 24-hour and 48-hour time groups and the Kencur extract treatment group and the 24-hour and 48-hour time groups
