In addition, high doses of radiation, especially during the first 3 days of healing, significantly reduce wound tensile strength. Protein deficiency impairs the proliferative phase by impeding angiogenesis, fibroblast proliferation and collagen production, reducing overall connective tissue formation (Gogia, 1999; Guo and DiPietro, 2010).

Vasodilation of area vessels allows plasma like fluid to leak into the tissue space. Different tissues have their own normal rates of growth during the process of healing; the optimal rate is approached when factors advantageous to healing are present and factors having the ability to disturb or retard the healing processes are controlled or absent. The colour and condition of the granulation tissue is often an indicator of how the wound is healing. Additionally, an in-depth understanding of the physiological macro- and micronutrient requirements along each stage of the wound-healing process allows for supplementation as individually required. They wanted to find out how effective the treatment is at killing microbes, and which combination worked best. Cellular activity reduces and the number of blood vessels in the wounded area regress and decrease.
