BACKGROUND:Mesenchymal stem cells (MSCs) may serve as immunoregulators by producing various anti-inflammatory molecules. Under sufficient level of TNF-α, MSCs become activated and adopt immune-suppressive phenotype (MSCs type-2) by releasing various anti-inflammatory molecule including TGF-β and IL-10. However, the ability of MSC itself to produce IL-10 under TNF-α stimulation and the correlation of TGF-β production of MSCs to IL-10 level remains to be elucidated.AIM:In this study, MSCs were activated with various TNF-α doses to determine the increase of IL-10 and TGF-β level as well as its correlation.MATERIAL AND METHODS:This study used post-test only control group design, by using 3 study groups, consist of 1 control (C) and 2 treatments (T) (TNF-α = 5 and 10 ng/mL) with triplicate induced in MSC for 24 hours, then the levels of IL-10 and TGF-β were measured by using ELISA assay.RESULTS:The results of this study showed a significant increase of TGF-β and IL-10 levels (p < 0.05) at TNF-α 5 and 10 ng/mL dose of TNF-α. Moreover, there was a significant negative correlation between TGF-β and IL-10 level on 5 and 10 ng/mL dose TNF-α treatment.CONCLUSION:Based on our study, we conclude that the 5 ng/mL dose of TNF-α is a sufficient dose for MSCs to suppress the inflammatory milieu. The higher increase of TGF beta is due to the controlled inflammation by IL-10.
Introduction: The massive hepatic necrosis of acute liver failure (ALF) results in a sudden loss of hepatic cells. Although most hepatocyte cells of ALF are completely lost, stem cell-derived circulating cells and endogenous progenitor cells rapidly regenerate them. Mesenchymal stem cells (MSCs) have a critical role in the regeneration of liver injury through regulating platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) levels. However, their fluctuating levels in the healing process and correlation to the decrease of liver function markers remain unclear. The aim of this study was to analyze the effects of MSCs in accelerating liver regeneration of ALF by measuring VEGF and PDGF levels on day 2 and 7, as well as SGPT and SGOT levels, and assessing histopathology appearance. Methods: Using an ALF rat model, 12 animals were randomly assigned into two groups: umbilical cord (UC)-MSC injection (T1) and vehicle control (Veh). ELISA assay was employed to measure PDGF and VEGF levels, an automatic analyzer was used to assess serum glutamic pyruvic transaminase (SGPT) and serum glutamic oxaloacetic transaminase (SGOT), and hematoxylin and eosin (H&E) staining was used to evaluate morphological appearance. Results: The study showed an significant (P<0.001) increase of PDGF and VEGF levels on the 2nd day, followed by a decrease on the 7th day, along with a decrease of SGPT and SGOT levels as well as the normality of histology appearance. Conclusion: In conclusion, administration of MSCs may accelerate liver regeneration of ALF through PDGF and VEGF regulation.
Full-thickness wound are areas damage of skin associated with loss of epidermis and dermis. The wound healing mechanism consists proliferation, migration and remodeling. Hypoxic conditional medium of mesenchymal stem cells (HMSCs-CM) contains lots of soluble molecules, such as protein growth factor and cytokine anti-inflammation. The soluble molecule of HMSCs-CM plays a critical role in wound healing by upregulation of VEGF and collagen synthesis. The objective of this study was to evaluate the effect of HMSCs-CM on VEGF and collagen concentrations in rats with incised wounds. The methods of this study were an experimental animal study with post-test only control group design was performed involving 24 Wistar rats. The rats were randomized into four groups consisting of sham, control and two treatment groups (gel of HMSCs-CM at doses of 200 μL and 400 μL). The VEGF levels and collagen density were analyses using ELISA assay and Masson-trichome specific staining, respectively. One-way ANOVA and Post Hoc LSD were used to analyses the data. The results of this study showed that a VEGF levels was significant increased on day 6 with doses-dependent manner. Interestingly, the VEGF levels gradual decrease on day 9. In addition, the decreased of VEGF levels on day 9 in this study in line with our findings in which we found there was a trend in the decreased of collagen density, it indicated the completion of remodeling phase and there has been an acceleration in wound healing. This study demonstrated that HMSCs-CM were able to regulate VEGF levels and collagen synthesis in accelerate wound healing. The role of HMSCs-CM stimulate cutaneous wound healing should be clarified further.Keywords: hypoxic conditional medium of mesenchymal stem cells (HMSCs-CM), vascular endothelial growth factor, collagen synthesis, paracrine factors
<p>Diabetes Melitus ialah penyakit yang ditandai dengan nilai kadar HbA1c >7%. Hampir 80% pasien Diabetes Mellitus Tipe II mengalami kematian. Kepatuhan dalam meminum obat merupakan peran penting bagi penderita penyakit Diabetes Melitus tipe II. Perlu adanya peningkatan kepatuhan dalam penggunaan obat sehingga keberhasilan dalam pengobatan tercapai serta nilai kadar indeks glikemik yang terkontrol. Tujuan penelitian ini adalah untuk mengetahui hubungan kepatuhan penggunaan obat dengan indeks glikemik kontrol pada pasien Diabetes Melitus di Rumah Sakit Islam Sultan Agung Semarang. Penelitian ini merupakan penelitian pra-eksperimental dengan rancangan <em>The one Group Pretest-Posttes</em> dilakukan secara cross sectional. Sampel sebanyak 96 pasien yang diberikan kuisioner kepatuhan ARMS diambil di Rumah Sakit Islam Sultan Agung Semarang Pengambilan data dilakukan pada periode Agustus-Oktober 2020 di Rumah Sakit Islam Sultan Agung Semarang. Penelitian ini didapatkan hasil 0,000 yang dikatakan terdapat indeks glikemik kontrol HbA1c pada pasien Diabetes Melitus type II di Rumah Sakit Islam Sultan Agung Semarang menunjukan nilai <em>p 0</em><em>,000</em> <em>(p</em> < 0,05) bahwa terdapat hubungan kepatuhan penggunaan obat dengan Indeks glikemik kontrol kadar HbA1c.</p>
People with diabetes are often unaware of the side effects of the medications they take, including both oral diabetic medications and insulin. This program is provided in an effort to empower the Indonesian Diabetes Association (Persadia) Semarang City Branch's training on monitoring pharmacological side effects in diabetes mellitus patients who are self-isolating. It is hoped that by participating in this activity, drug compliance would improve, the death rate from diabetes will reduce, and the complexity of comorbidities will be avoided. The results of implementing this program, namely monitoring the side effects of taking diabetic mellitus drugs in Persadia members, can raise understanding of side effect symptoms, resulting in increased adherence to diabetes drug use and better blood sugar control.
