Penyakit jantung merupakan salah satu penyakit penyebab angka kematian tertinggi di dunia. Penyakit jantung terutama disebabkan oleh aterosklerosis yaitu kondisi plak yang menumpuk di arteri. Plak ini akan mengeras dan mempersempit pembuluh darah sehinggga tubuh akan kekurangan suplai oksigen yang dibutuhkan. Salah satu faktor yang mengawali proses aterosklerosis adalah LDL yang teroksidasi yang dipicu stres oksidatif. Stres oksidatif dapat dihambat dengan memberikan antioksidan seperti antosianin. Antosianin ini bisa didapatkan dari ubi ungu (Ipomoea batatas L) varietas ungu yang banyak terdapat di Malang. Penelitian ini dilakukan untuk mengetahui efek antosianin dari Ipomoea batatas varietas ungu kultivar Gunung Kawi pada kadar superoxide dismutase (SOD) pada kondisi aterosklerosis. Desain penelitian ini adalah eksperimental dengan membandingkan tikus dengan diet normal, tinggi lemak, dan diet tinggi lemak yang diberi antosianin lalu diukur kadar SOD dalam serum dengan metode spektrofotometri. Hasil penelitian menunjukkan bahwa pada kelompok diet normal (K-) didapatkan kadar SOD 2,6+0,490 µg/ml, diet tinggi lemak (K+) 2,2+1,020 µg/ml, perlakuan A (antosianin 5 mg/BB/hari) 3+0,632 µg/ml, perlakuan B (antosianin 10 mg/BB/hari) 3,1+0,683 µg/ml, dan perlakuan C (antosianin 20 mg/BB/hari) 3,4+0,1,170 Ug/ml. Hasil uji statistik one way ANOVA diketahui bahwa tidak terdapat perbedaan kadar SOD yang signifikan antar kelompok perlakuan (p=0,308). Penelitian ini menyimpulkan bahwa antosianin dari Ipomoea batatas varietas ungu kultivar Gunung Kawi tidak meningkatkan kadar SOD pada tikus Wistar (Rattus novergicus) dengan diet tinggi lemak.
Immune response in sepsis divided into two phases, hyperinflammation (cytokine storm) and hypo-inflammation (immunosuppression). The mechanism of immunosuppression appears to involve apoptosis of immune cells, particularly mononuclear cells and it predisposes to secondary infection that is believed as the predominant driving force for mortality. We aimed to determine the effect of ketamine on mononuclear cells count related to intracellular calcium contained within these cells during the immunosuppression phase of sepsis. This in vivo study was performed in Rattus Novergicus with Fecal Induced Perionitis (FIP) procedure to induce polymicrobial sepsis. Rats were treated with each respective dose of ketamine (2.5, 5, and 10 mg/kg) 1 hour after sepsis induction. Murine Sepsis Score was measured at 1 and 24 hours post-FIP. After 24 hours, animals were sacrificed, and the percentage of intracellular calcium inside CD4, and CD8 T cells, B cells and monocytes, along with these cells counts were determined with flowcytometry. There is significant elevation of intracellular calcium in CD4 T-cells, B-cells and monocytes after FIP-induction and ketamine treatment suppressed this FIPinduced elevation. Measurement of mononuclear cells count showed a relevant result, in which FIP induced mononuclear cells massive loss and ketamine could inhibit the loss. MSS data showed ketamine 5 mg/kg could improve 24 hours MSS with 100% survivability. These findings suggest that ketamine have an inhibitory effect in mononuclearcells apoptosis mechanism through attenuating intracellular calcium elevation in polymicrobial sepsis. These inhibitory effects of ketamine might correlate with a better survival and clinical outcome.
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.
