Abstract

BackgroundWounds are areas of physical or thermal damage of the epithelial layer of skin or mucosa. The wound healing process consists of hemostasis, inflammation, proliferation, and remodeling. Mesenchymal stem cells (MSCs) play a role in wound healing by suppressing potent pro-inflammatory molecules, such as tumor necrosis factor-α (TNF-α), leading to macrophage polarization from the pro-inflammatory type to the pro-regeneration type characterized by increasing vascular endothelial growth factor (VEGF) production. MSCs are able to increase VEGF level in-vivo correlated with collagen synthesis. The objective of this study was to assess the role of TNF-α-activated MSCs on VEGF in rat wounds. MethodsAn 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 one control (K) and three treatment groups (P) (activated MSCs at doses of 3x105, 6x105, and 12x105 cells, respectively). The measurement of VEGF levels was done using ELISA assay while the collagen analysis was performed by light microscopy. One way ANOVA and Post Hoc LSD were used to analyze the data.ResultsThe results showed a significant increase in VEGF levels (p <0.05) on day 3 and then a significant decrease on day 5 along with a significant increase in the amount of collagen on day 7 (p<0.05).ConclusionThis study demonstrated that TNF-α-activated MSCs were able to regulate VEGF levels and collagen synthesis in wound healing in rats. The molecular mechanism by which TNF-α-activated MSCs stimulate cutaneous wound healing should be clarified further.

Abstract

Jumlah perokok dan jumlah rokok yang dikonsumsi mengalami peningkatan dari waktu ke waktu. Rokok dapat memengaruhi trombosit yang dapat menyebabkan gangguan kardiovaskular. Penelitian ini merupakan penelitian potong lintang yang bertujuan untuk menganalisis lama merokok dan jumlah rokok yang dikonsumsi terhadap jumlah trombosit, mean platelet volume (MPV), platelet distribution width (PDW), platelet crit (PCT), dan platelet large cell ratio (PLCR). Penelitian dilakukan di Pabrik Garmen Cimahi pada tahun 2014 yang diikuti oleh 31 laki-laki perokok aktif berusia 19 - 50 (32,97 + 10,28) tahun, 70,9% di antaranya sebagai perokok sedang. Analisis data dilakukan secara deskriptif, uji normalitas Shapiro-Wilk, dan uji korelasi Spearman’s rho. Peserta telah merokok selama minimal dan maksimal dengan rata-rata (+ SB), yaitu 3 - 25 tahun (10,48 + 6,33) dan konsumsi rokok sebanyak 5 - 25 batang per hari (13,10 + 4,99). Jumlah trombosit 171 - 422 (280,9 + 56,2) x 10^3 sel/mm3, MPV 8,8 - 13,6 (10,14 + 0,93) fL, PDW 8,7 - 13,8 (10,27 + 1,22) fL, PLCR 14,4 - 38,8% (24,91 + 5,46), dan PCT 0,1 - 0,4%(0,28 + 0,06). Sebaran ukuran trombosit ditemukan normal, namun dengan ukuran besar sesuai nilai MPV dan PLCR yang tinggi. PCT normal berkorelasi sangat kuat dengan jumlah trombosit. Jumlah batang rokok yang dikonsumsi berkorelasi lemah dengan lamanya merokok. Lama merokok dan jumlah rokok yang dikonsumsi berkorelasi negatif dengan jumlah trombosit, MPV, PDW maupun PLCR.Smoking Period and Number of Cigarette Consumption with Thrombocyte among Active Male SmokersNumber of smokers and cigarette consumption are increasing from time to time. Cigarettes influence thrombocytes which may cause cardiovascular disorder. This study was a cross sectional study aiming to analyze smoking period and cigarette consumption number toward the number of thrombocytes, MPV, PDW, PCT and PLCR. This study was conducted at Cimahi Garment Factory in 2014 participated by 31 active male smokers in age of 19 - 50 (32,97+10,28) years old in which 70,9% of them were medium smokers. Data analysis was conducted descriptively, using Shapiro-Wilk normality test and Spearman’s rho correlation test. Participants had been smoking for the minimum and maximum 3 - 25 (10.48 + 6.33) years and 5 - 25 (13.10 + 4.99) cigarettes in average per day. The number of thrombocytes was worth 171 - 422 (280,9 + 56,2)x10^3 cells/mm3, MPV 8.8 - 13.6 (10.14 + 0.93) fL, PDW 8.7 - 13.8 (10.27+ 1.22) fL, PLCR 14.4 - 38.8% (24.91 + 5.46) and PCT 0.1 - 0.4% (0.28 + 0.06). PDW was found normal with the giant shape in accordance with the high MPV and PLCR value. PCT was normal correlated strongly with thrombocyte number. The cigarette consumption number had a weak correlation with the smoking period. The smoking period and the cigarette consumption number had a negative correlation with the number of thrombocytes, MPV, PDW and PLCR.
