Abstract

Penggunaan handphone sudah menjadi bagian dari gaya hidup masyarakat. Hal ini  merupakan sebuah ancaman serius untuk kesehatan manusia. Paparan gelombang Elektromagnetik (EM) dapat menyebabkan gangguan pada otak manusia baik pada struktur, fungsi maupun aspek biokimiawinya. Stres akibat paparan gelombang EM dapat mengganggu fungsi memori. Penelitian ini bertujuan untuk mengetahui ada atau tidaknya perbedaan nilai memori kerja pada tikus putih  (Rattus norvegicus) jantan galur Sprague dawley. Pada penelitian ini digunakan 18 ekor tikus putih (Rattus norvegicus) galur Sprague dawley, berusia 2-3 minggu dibagi ke dalam 3 kelompok,  yaitu kelompok kontrol (K), kelompok perlakuan 1 (P1) dipaparkan dengan gelombang EM dari handphone 1 jam/hari (P1), dan P2 dipaparkan dengan durasi 3 jam/hari selama 14 hari. Pengujian memori kerja menggunakan radial arm maze. Hasil rerata memori kerja pada masing-masing kelompok adalah sebagai berikut K: 2%, P1: 1,33%, P2: 2,33%. Dari hasil analisa One Way ANOVA didapatkan nilai p=0,55 (p>0,05). Simpulan, paparan gelombang EM handphone selama 14 hari tidak mempengaruhi kemampuan memori kerja tikus putih  (Rattus norvegicus) jantan galur Sprague dawley. [JuKe Unila 2015; 5(9):13-17]

Abstract

Ebola hemorrhagic fever is one of at least 30 known viruses capable of causing viral hemorrhagic fever syndrome. It is a severe, often fatal disease in humans and nonhuman primates (such as monkeys, gorillas, and chimpanzees). Ebola first appeared in 1976 in 2 simultaneous outbreaks, in Nzara, Sudan, and in Yambuku, Democratic Republic of Congo. The latter was in a village situated near the Ebola River, from which the disease takes its name. The current (2014) Ebola virus outbreak in West Africa has seized the world's attention, because this become the deadliest Ebola outbreak in recorded history and it is significant and primarily involves 4 African countries—Guinea, Liberia, Sierra Leone, and Nigeria. Besides the high mortality rate, the cure for Ebola disease has not been found yet. As of Augustus 31, 2014, 3.707 total suspected or confirmed cases (2.106 laboratory-confirmed) had been reported in these countries, resulting in 1.848 deaths. Based on genetic analysis, the virus is 97% identical to the Zaire ebolavirus identified in recent (earlier in 2014) cases in Gabon and the Democratic Republic of the Congo. Ebola disease management generally in the form of therapeutic support, relieve symptoms, and focus on the early identification of complications. Prognosis is poor, especially Ebolavirus Zaire strain, which has a case fatality rate of up to 89%. [JuKe Unila 2014; 4(8):245-253]
