RESUMO
BACKGROUND: Covid-19 has become pandemic in the World, including Indonesia. Our last study showed that HSF could serve as an immunomodulator. Using the exact search, we found that the most immuno-dominant SARS-COV2 epitope, namely A spike protein epitope, B envelope protein epitope, and C membrane protein epitope, we concise to be HF. MATERIALS AND METHODS: We used to post only control design study and mice as an animal model. The research divided mice into four groups, and the first group as control received PBS as a placebo. The second, three, and last four groups gave HF, HSN, and HFHSN (combine HF and HSN). All of the regiment enters the mouth with a special sonde to reach the gastrointestinal organ. We gave HF every week three times and HSN once a day. After administration regiments for a long three weeks, we sacrificed the mice. We evaluated cellular immune responses that are Th-2, Th-17, and NK cells. We check for humoral immune response, TGF-ß,IL-17A, IL-4, IgG,IL-4, ß-defensin, and s-IgA. RESULTS: Highest profile cellular immunity HF, HSN, and HFHSN were NK cell, Th-2 and Th-17, and the last NK cell, respectively. After that which in humoral immunity, the domination response IgG and IL-4 were HF. But HSN and HFHSN dominated for s-IgA and ß-defensin production. By using the study Bio-Informatica, we found HF. CONCLUSION: If the results of this study are continued to the clinical trial level, it is necessary to recommend additional markers such as CTL (s-IgA and ß-defensin in lung tissue)and CPE assay.
RESUMO
Background Type 2 diabetes mellitus (T2DM) is a major risk factor of atherosclerosis. Hyperglycemia in T2DM causes advanced formation of glycation end products (AGE) which leads to oxidative stress and chronic inflammation. Oxidative stress occurs due to increased levels of reactive oxygen species (ROS) such as H2O2. On the other hand, lipoprotein-associated phospholipase (Lp-PLA2) has pro-inflammatory effects, which cause instability of atherosclerosis plaques. This condition causes hypoxemic cells to stimulate HIFα induced vasa vasorum angiogenesis. This study aims to understand the potential of PSP as an anti-angiogenic agent through decreased levels of H2O2 and Lp-PLA2 leading to the decline of vasa vasorum angiogenesis in diabetic rat model. In addition, this study also measured the lipid profile of diabetic rat model in relation to vasa vasorum angiogenesis. Methods True laboratory experiment with randomized post-test control of group design using 25 wistar rats (Rattus norvegicus) were divided into five groups; one normal group and four group with High Fat Diet (HFD) and low dose streptozotocin (30 mg/kgBW) injection sc, treated with placebo and three various doses of PSP 50, 150, 300 mg/kgBW. Results ANOVA test (p < 0.05) shows that there is a significant influence of polysaccharide peptide (PSP) feeding on the decreased amount of vasa vasorum angiogenesis (p = 0.00), lipid profile (cholesterol total and triglyceride; p = 0.01, p = 0.001), and amount of H202 (p = 0.003). The amount of Lp-PLA2 declined to (p = 0.184). This result indicates that PSP prevents inflammation in atherosclerosis. Conclusions PSP of Ganoderma lucidum is an anti-angiogenic agent in T2DM.
