Edema serebral secara komprehensif didefinisikan sebagai peningkatan patologis pada jumlah air otak keseluruhan yang mengarah ke peningkatan volume otak. Edema di otak dapat diklasifikasikan secara topografi menjadi fokal atau global. Sesuai penyebabnya dapat dikategorikan sebagai sitotoksik, vasogenik, interstisial, atau gabungan. Gejala edema serebral tidak spesifik dan berkaitan dengan efek sekunder massa, kompresi vaskular, dan herniasi. Klinis dan perubahan radiologis biasanya reversibel pada tahap awal selama penyebab yang mendasari dikoreksi. Edema cerebral perlu dibahas lebih khusus pada patofisiologi dan penatalaksanaan. Diharapkan dengan pemahaman patofisiologi serta penatalaksanaan yang cepat dan tepat akan mampu meningkatkan prognosa pasien dengan edema cerebral.
Ekstrak propolis mempunyai efek neuroprotektan melalui berbagai macam cara kerja salah satunya sebagai antioksidan karena bahan kandungan utamanya adalah flavonoid. Penelitian ini bertujuan untuk menguji efek ekstrak propolis berbagai dosis dalam meningkatkan ekspresi Bcl-2 dan menurunkan apoptosis sel otak tikus model cedera otak traumatik. Tikus dibagi menjadi 5 kelompok, yaitu: kelompok normal, kelompok yang diberi perlakuan cedera otak traumatis, kelompok yang diberi perlakuan cedera otak traumatis dan ekstrak propolis masing-masing dosis 50mg/kgBB, 100mg/kgBB, dan 200mg/kgBB. Setiap kelompok diambil otaknya untuk diperiksa ekspresi Bcl-2 dan apoptosis sel otak pada hari ke-7. Berdasarkan hasil analisa statistik, didapatkan hubungan signifikan antara ekspresi Bcl-2 dan apoptosis sel otak tikus model cedera otak traumatik dengan berbagai dosis ekstrak propolis (p<0,05). Dosis 200mg/kgbb merupakan dosis yang paling efektif dalam meningkatkan ekspresi Bcl2 otak tikus dan menurunkan apoptosis sel otak tikus. Penelitian ini telah membuktikan bahwa ekstrak propolis dapat meningkatkan ekspresi Bcl-2 dan menurunkan apoptosis sel otak tikus model cedera otak traumatik.Kata Kunci: Apoptosis sel, cedera otak traumatik, ekspresi Bcl-2, ekstrak propolis
Background: More than 30 times earthquake occurred in Indonesia in the periode 2016-2017 and 23 times occurred in 2018. It made people more anxious. This is also a warning of the coming of the doom which is explained in several verses of the Qur'an. One of them is surah al-Insyiqaq. Understanding the meaning of this surah is expected to increase anxiety or feelings of surrender. These emotions can affect brain activity and can be recorded withElectroencephalography (EEG). To date, there has been no specific study of alpha wave activity when surah al-Insyiqaq is played between groups who understand the meaning of the surah and those who do not understand.Objective: Comparing the alpha brain wave activity during listening surah al-Insyiqaq in the control group and the treatment group.Method: This research is a study using experimental methods conducted on 20 subjects using simple random sampling. Subject were divided into two groups, the control group, and the treatment group. The treatment group was given a booklet, video and lecture about the contents of the surah. Brain wave activity was measured before and after the intervention using EEG during the subject listens to murottal of the surah.Results: There is a significant difference in understanding the meaning of Surat al-Insyiqaq between the results of the post test control group and the treatment group that was previously given the intervention (p=0,041). The significance value of the difference in alpha wave activity in the two groups was performed using the Independent t test and obtained p = 0.033.Conclusion: Understanding surah al-Insyiqaq creates a feeling of calm and surrender to God. This can lead to greater alpha brain wave activity when listening to surah al-Insyiqaq than those who are not given an understanding of the meaning of surah al-Insyiqaq.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
