Protective Effects of Trimetazidine on Bone Marrow Mesenchymal Stem Cells Viability in an ex vivo Model of Hypoxia and in vivo Model of Locally Myocardial Ischemia

Bone marrow mesenchymal stem cells (MSCs) have shown potential for cardiac repair following myocardial injury,but this approach is limited by their poor viability after transplantation.The present study was to investigate whether trimetazidine (TMZ) could improve survival of MSCs in an ex vitro model of hypoxia,as well as survival,differentiation,and subsequent activities of transplanted MSCs in rat hearts with acute myocardial infarction (AMI).MSCs at passage 3 were examined for their viability and apoptosis under a transmission electron microscope,and by using flow cytometry following culture in serumfree medium and exposure to hypoxia (5% CO2,95% N2) for 12 h with or without TMZ.Thirty Wistar rats were divided into 3 groups (n=10 each group),including groupⅠ(AMI control),groupⅡ (MSCs transplantation alone),and group Ⅲ (TMZ+MSCs).Rat MSCs (4×107) were injected into peri-infarct myocardium (MSCs group and TMZ+MSCs group) 30 min after coronary artery ligation.The rats in TMZ+MSCs group were additionally fed on TMZ (2.08 mg?kg-1?day-1) from day 3 before AMI to day 28 after AMI.Cardiac structure and function were assessed by echocardiography at 28th day after transplantation.Blood samples were collected before the start of TMZ therapy (baseline),and 24 and 48 h after AMI,and inflammatory cytokines (CRP,TNF-α) were measured.Then the sur-vival and differentiation of transplanted cells in vivo were detected by immunofluorescent staining.The cellular apoptosis in the peri-infarct region was detected by using TUNEL assay.Furthermore,apoptosis-related proteins (Bcl-2,Bax) within the post-infarcted myocardium were detected by using Western blotting.In hypoxic culture,the TMZ-treated MSCs displayed a two-fold decrease in apoptosis under serumfree medium and hypoxia environment.In vivo,cardiac infarct size was significantly reduced,and cardiac function significantly improved in MSCs and TMZ+MSCs groups as compared with those in the AMI control group.Combined treatment of TMZ with MSCs implantation demonstrated further decreased MSCs apoptosis,further increased MSCs viability,further decreased infarct size,and further improved cardiac function as compared with MSCs alone.The baseline levels of inflammatory cyto-kines (CRP,TNF-α) had no significant difference among the groups.In contrast,all parameters at 24 h were lower in TMZ+MSCs group than those in MSCs group.Furthermore,Western blotting indicated that the expression of antiapoptotic protein Bcl-2 was upregulated,while the proapoptotic protein Bax was down-regulated in the TMZ+MSCs group,compared with that in the MSCs group.It is suggested that implantation of MSCs combined with TMZ treatment is superior to MSCs monotherapy for MSCs viability and cardiac function recovery.

Role of Trimetazidine in Coronary Artery Bypass Graft Surgery

Trimetazidine is a drug that has been used to reduce the damage of reperfusion injury, which is a mechanism of oxidative aggression that occurs in coronary syndromes, angioplasty procedures, as well as in cardiovascular surgeries. Seeking to improve myocardial protection during procedures that involve reperfusion, attention was recently turned to research on cytoprotective drugs which act on segments of cellular metabolism, used in isolation or combined to reduce or prevent damage to the cardiac cell. The aim of this review is to objectively evaluate the effects of the drug trimetazidine (TMZ) on ischemia-reperfusion injury in coronary artery bypass graft surgery by reviewing all known studies from recent years.

Tectona grandis (Teak Tree) Young Leaf Extract as a Histological Stain

Stains are applied to impart contrast to the tissue and identify particular features of interest. However, the use of synthetic dyes as staining reagents has been associated with significant human health challenges and pollution of the ecosystem. These developments have necessitated a shift towards using natural dyes that are eco-friendlier and readily available. We investigated the staining reaction patterns of teak tree leaves (Tectona grandis) dye extracts and explored their suitability as a cytoplasmic stain in micromorphological assessments. Dye extracts were prepared using acetone, methanol, and ethanol as solvents from air-dried (under shade) teak tree young leaves. The dye extracts were applied as a counterstain and evaluated against eosin in formalin-fixed paraffin-embedded (FFPE) bovine tissue sections at varying concentrations and different staining times. Teak tree leaves (Tectona grandis) dye extracts produced relatively varying staining intensities of reddish-brown cytoplasmic coloration when used on bovine tissue at different concentrations and staining times comparable to eosin and with blue-purple hematoxylin nuclear stain. The present study showed that Tectona grandis leaf dye extracts provide an excellent cytoplasmic staining pattern and can be used as an alternative counterstain in routine H&E staining techniques.
