through and through wound
1.The problems occur because the 5.56 mm bullet gains much of its lethality from two features: one is that (like all pointed bullets) it tumbles on impact, increasing the size of the wound channel; the other is that it often breaks up while tumbling, sending fragments through the body and increasing the severity of the wound.
2.Corneal wound-healing and histopathological changes of the ablation zone were studied through slit lamp, light microscope and transmission electronic microscope. The expression levels of collagen I, collagen III, fibronectin (FN) and transforming growth factor beta-1 (TGF-& 1) were investigated by immunohistochemistry and RT-PCR assays.
3.Through the segment observation before and after cutting the twig cutting of Robinia pseudoacacial(4n),the results showed: there are wound callus in the cutting slit,but find no root primordium in the wound calls;there are also no latent root primordium in the stem of Robinia pseudoacacial(4n) twig,adventitious root is formed by mutagenic root primordium growth,which sourced the fission and division of the medullar-ray cell.
4.Conclusion: Chinese herbs for replenishing qi and resolving stagnation can promote the wound healing in rats through reducing the expression of HIF-1α, accelerating the expression of VEGF in granulation tissue of skin ulcers in rats with diabetes and ameliorating the status of ischemia and hypoxia.
