Supplements with too much Vitamin A can be toxic to the liver since Vitamin A is a fat soluble vitamin (meaning more gets stored than excreted.) Sweet potatoes and other foods rich in Vitamin A, however, do not cause liver toxicity and can not be stored for long-term use like supplements can.
The wound healing stages are made up of three basic phases: inflammation, proliferation and maturation. There are many types of wounds that require different wound care products for proper recovery from an ulcer or laceration, but most go through similar healing stages.
This stage lasts until about 48 h after injury. Depicted is a skin wound at about 24â48 h after injury. The wound is characterized by a hypoxic (ischaemic) environment in which a fibrin clot has formed. Bacteria, neutrophils and platelets are abundant in the wound. Normal skin appendages (such as hair follicles and sweat duct glands) are still present in the skin outside the wound. b, New tissue formation. This stage occurs about 2â10 days after injury. Depicted is a skin wound at about 5â10 days after injury. An eschar (scab) has formed on the surface of the wound. Most cells from the previous stage of repair have migrated from the wound, and new blood vessels now populate the area.
