Background: The neurotrophins nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) is a family of polypeptides that play critical role during neuronal development, appear to mediate protective role on neurorepair in ischemic stroke. Naturally in adult brain neurorepair process consist of: angiogenesis, neurogenesis, and neuronal plasticity, it can also be stimulated by endogenous neurorepair. In this study we observed correlation between NGF and BDNF ischemic stroke patient's onset: 7-30 and over 30 days. Methods: This is cross sectional study on 46 subjects aged 38 -74 years old with ischemic stroke from The Indonesian Central Hospital of Army Gatot Subroto Jakarta. Diagnosis of ischemic stroke was made using clinical examination and magnetic resonance imaging (MRI) by neurologist. Subjects were divided into 2 groups based on stroke onset: 7 -30 days (Group A: 19 subjects) and > 30 days (Group B: 27 Subjects). Serum NGF levels were measured with ELISA method and BDNF levels were measured using multiplex method with Luminex Magpix. Results: Levels of NGF and BDNF were significantly different between onset group A and B (NGF p= 0.022, and BDNF p=0.008), with mean levels NGF in group A higher than group B, indicating that BDNF levels is lower in group A than group B. There was no significant correlation between NGF and BDNF levels in all groups. Conclusion:The variations in neurotrophic factor levels reflect an endogenous attempt at neuroprotection against biochemical and molecular changes after ischemic stroke. NGF represents an early marker of brain injury while BDNF recovery is most prominent during the first 14 days after onsite but continuous for more than 30 days. There is no significant correlation between NGF and BDNF in each group.
Gangguan ginjal akut (GnGA) merupakan suatu keadaan dimana proses laju filtrasi glomerulus ginjal menurun secara cepat yang menyebabkan retensi nitrogen terutama kreatinin dan blood urea nitrogen (BUN). Kondisi ini dapat dinetralkan dengan mengkonsumsi antioksidan dari luar tubuh seperti Propolis (metode CMCE). Untuk mengetahui pengaruh ekstrak propolis (metode CMCE) terhadap kadar MDA dan degenerasi tubulus renalis. Penelitian ekperimental dengan pendekatan post test only control group design. Subyek penelitian berjumlah 25 ekor tikus jantan galur wistar yang dibagi secara acak menjadi 5 kelompok. Kelompok K1 tanpa diinduksi gentamisin. Kelompok K2 diinduksi gentamisin dan tanpa diberi ekstrak propolis metode CMCE. Kelompok P1, P2 dan P3 diinduksi gentamisin dan ekstrak propolis metode CMCE masing-masing dengan dosis 200, 400, 800 mg/k, BB per hari per oral selama 7 hari. pemeriksaan kadar Malondialdehid (MDA) di IBL FK UNISSULA dan pemeriksaan degenerasi tubulus renalis di RSI Sultan Agung Semarang pada Maret - Juli 2020. Uji One Way Anova menunjukkan perbedaan bermakna pada kadar MDA dan degenerasi tubulus renalis menunjukkan perbedaan bermakna (p<0,05). Pemberian ekstrak propolis metode CMCE menunjukan berpengaruh secara signifikan terhadap kadar MDA dan skor total degenerasi tubulus renalis yang diinduksi gentamisin.
Obesity is a pathological condition in which there is an excess body fat due to imbalance energy expenditure. Its association with oxidative stress could cause other metabolic disorders such as endothelial dysfunction, atherosclerosis, and cardiovascular disease. Theaim of this study was to assess the correlation of oxidative stress (F2-Isoprostane, Superoxide dismutase and Myeloperoxidase) andendothelial dysfunction (Asymmetric dimethylarginine) which happened in central obese men. A cross sectional study was carried outin 62 central obesity male subjects with ages range between 30−60 years. The researcher determined SOD activity, concentration ofMPO as well as ADMA. In this study was found a significant correlation of F2-Isoprostan (r = 0.333, p = 0.008), MPO (r = 0.386; p = 0.008) and ADMA but not with SOD. The elevated concentration of F2-Isoprostane occur 3.5 times (p = 0.02; 95%; CI = 1.19–10.19), elevated MPO occur 3.7 times (p = 0.023; 95%; CI = 1.16–11.56) while combination of elevated F2-Isoprostane-MPO occur6.7 times (p = 0.011; 95%; CI = 1.33-33.24) will increase the risk of endothelial dysfunction. There was a significant correlation of oxidative stress with endothelial dysfunction, and the increase concentration of F2-Isoprostane and MPO indicates the occurrence of endothelial dysfunction in central obesity.
Hiperkolesterolemia mengakibatkan terjadinya peningkatan produksi ROS yang menimbulkan stress oksidatif dengan peningkatan Lipid Peroksidase (LPO) yang menyebabkan infertilitas dengan penurunan kadar testoteron. Kondisi ini dapat dinetralkan dengan mengkonsumsi antioksidan dari luar tubuh seperti N-Acetylcysteine (NAC). Untuk mengetahui pengaruh pemberian NAC terhadap hormon testoteron yang diberi diet tinggi kolesterol. Penelitian ekperimental dengan pendekatan post test only control group design. Subyek penelitian berjumlah 24 ekor tikus jantan galur sparague dawley yang dibagi secara acak menjadi 4 kelompok. Kelompok K1 tanpa pemberian NAC dan diet tinggi kolesterol. Kelompok K2 tanpa pemberian NAC namun diberi diet tinggi kolesterol. Kelompok K3 dan K4 diberi diet tinggi kolesterol dan NAC masing-masing dengan dosis 3,14 mg/ml dan 6,3 mg/ml. Hari ke 25 dilakukan pengambilan darah untuk pemeriksaan kadar testoteron di IBL FK UNISSULA pada November - Desember 2020. Uji One Way Anova menunjukkan perbedaan bermakna pada kadar testoteron menunjukkan perbedaan bermakna (p=0,021). Hasil uji Post Hoc Tukey kadar testoteron pada K1 dan K4 menunjukkan perbedaan signifikan terhadap K2 (p<0,05). Pemberian NAC menunjukan secara bermakna dapat meningkatkan kadar hormon testoteron yang diberi diet tinggi kolesterol.
