Abstract. Sorghum bicolor L. Moench is widely grown all over the world for food and feed. The effects of sorghum extracts on general inflammation have been previously studied, but its anti-vascular inflammatory effects are unknown. Therefore, this study investigated the anti-vascular inflammation effects of sorghum extract (SBE) and fermented extract of sorghum (fSBE) on human aortic smooth muscle cells (HASMCs). After the cytotoxicity test of the sorghum extract, a series of experiments were conducted. The inhibition effects of SBE and fSBE on the inflammatory response and adhesion molecule expression were measured using treatment with tumor necrosis factor-α (TNF-α), a crucial promoter for the development of atherosclerotic lesions, on HASMCs. After TNF-α (10 ng/mL) treatment for 2 h, then SBE and fSBE (100 and 200 μg/mL) were applied for 12h. Western blotting analysis showed that the expression of vascular cell adhesion molecule-1 (VCAM-1) (2.4-fold) and cyclooxygenase-2 (COX-2) (6.7-fold) decreased, and heme oxygenase-1 (HO-1) (3.5-fold) increased compared to the TNF-α control when treated with 200 μg/mL fSBE (P<0.05). In addition, the fSBE significantly increased the expression of HO-1 and significantly decreased the expression of VCAM-1 and COX-2 compared to the TNF-α control in mRNA level (P<0.05). These reasons of results might be due to the increased concentrations of procyanidin B1 (about 6-fold) and C1 (about 30-fold) produced through fermentation with Aspergillus oryzae NK for 48 h, at 37 °C. Overall, the results demonstrated that fSBE enhanced the inhibition of the inflammatory response and adherent molecule expression in HASMCs.

Background: Uric acid is a final product or a waste that is resulted from the metabolism of purines. A high level of uric acid (hyperuricemia) will cause several health problems, such as vascular inflammation, smooth muscle proliferation, and vascular lesion in kidneys. The syzygium polyanthum leaves contain bioactive substances that may affect the level of uric acid in blood. Objective: This study aimed to determine the influence of boiled water of syzygium polyanthum leaves to the changes of uric acid levels in the target area of Puskesmas Pandak 1 Bantul. Methods: This study employed pre- and post-test without control group design. The population consisted of all patients with hyperuricemia in the target area of Puskesmas Pandak 1 Bantul. Sample was selected with a concecutive sampling, gaining a total number of 24 respondents. Data were analyzed with the Wilcoxon test. The dose of boiled water of syzygium polyanthum leaves intake was 0.36g/ KgBW, once a day for 14 days. Result: This research showed that the boiled water of syzygium polyanthum leaves decreased hyperuricemia (uric acid levels), along with the significancy value of 0.009 (p <0.05). At the pre-test time, the average level of uric acid reached 7.279 mg/dl, and after the treatment, it decreased to 6.76 mg/dl. Conclusion: This study has established evidence that the boiled water of syzygium polyanthum leaves is able to decrease hyperuricemia (uric acid level in blood).

SummaryIn critically ill patients, the massive release of angiopoietin-2 (Ang-2) from Weibel-Palade bodies interferes with protective angiopoietin-1 (Ang-1)/Tie2 signalling in endothelial cells, thus leading to vascular inflammation and subsequent organ-dysfunction. We hypothesised that plasma exchange (PE) is efficient for lowering excess Ang-2 levels in critically ill patients with thrombocytic microangiopathy (TMA) or anti-glomerular basement membrane (anti-GBM) disease. Plasma Ang-1 and Ang-2 were measured by immuno-luminometric assays in patients with TMA (n=9) or anti-GBM disease (n=4) before and after up to four PE sessions. Twenty apparently healthy volunteers served as controls. Median (IQR) plasma levels of Ang-2 were markedly increased in patients with TMA (7.3 (2.4–21.1) ng/ml) and anti-GBM disease (5.8 (3.4–7.0) ng/ml) compared to healthy controls (1.0 (0.9–1.4) ng/ml, p <0.001). Moreover, Ang-1 plasma levels were decreased in both, TMA (1.02 (0.62–1.62) ng/ml) and anti-GBM disease patients (0.74 (0.59–3.62) ng/ml) compared to healthy controls (2.5 (1.93–3.47) ng/ ml, p <0.005). During a total of 32 treatments, PE effectively lowered elevated mean (SD) Ang-2 plasma levels by 36.7 ± 19.6 % per treatment (p <0.0001), whereas low Ang-1 plasma levels remained unchanged (0.3 ± 58.5 %; p =0.147). Ang-2 levels declined to almost normal values during ≤4 PE treatments (Friedman´s test p <0.0001). PE is an effective method to remove excess circulating Ang-2. It remains to be elucidated if the removal of Ang-2 is crucial to ameliorate endothelial damage in critically ill patients with severely altered endothelial integrity.
