Lymphatic density (LD; a) and blood vessel density (BD; b) in the myocardium

, LDs in the normal myocardium and the seven categorized stages. LD means the total number of D2-40+ lymphatics in 20 fields of view observed by light microscopy at ×200 magnification. The values of LD are 21.2 ± 6.2 in the normal myocardial tissue (Normal), 7.6 ± 4.2 in Stage I, 0 in Stage II, 0 in Stage III, 1.3 ± 1.5 in Stage IV, 22.3 ± 25.7 in Stage V, 29.7 ± 25.0 in Stage VI and 20.8 ± 13.4 in Stage VII. There is no statistical difference between LD values in Stages V, VI and VII. Statistical analyses were performed by Student's -test. * 0.0001; ** 0.05. , Blood vessel density (BD) in the normal myocardium and the seven categorized stages. BD means the total number of CD34+ blood vessels counted by the same methods as the value of lymphatic density. The values of BD are 2693.4 ± 197.0 in Normal, 1689.9 ± 640.7 in Stage I, 571.4 ± 478.3 in Stage II, 51.8 ± 30.5 in Stage III, 1430.8 ± 323.1 in Stage IV, 1292.7 ± 153.1 in Stage V, 509.9 ± 276.3 in Stage VI and 130.5 ± 83.8 in Stage VII. After the onset of myocardial infarction, the BD value decreased up to Stage III. The BD values increased in Stage IV compared with Stage III, but decreased with the advance of the healing process of infarcted lesion up to Stage VII. Statistical analyses were performed by Student's -test. * 0.001; ** 0.0001.<p><b>Copyright information:</b></p><p>Taken from "Lymphangiogenesis in myocardial remodelling after infarction"</p><p></p><p>Histopathology 2007;51(3):345-353.</p><p>Published online 01 Sep 2007</p><p>PMCID:PMC2366023.</p><p>© 2007 The Authors.
