| The eyebrows can be lost through a variety of causes, such as avulsion injury, thermal or radiation burns, operations for neoplasm, or diseases such as syphilis, leprosy, and alopecia areata. The bilateral superficial temporal arteries must be intact in bilateral eyebrows reconstruction operation. Injuried unilateral superficial temporal artery, the surgery was difficult. In 1995 Prof Qi KM reported eyebrows reconstruction by two island hair-bearing scalp flaps in one superficial temporal arterial pedicle. Although the result is satisfaction, clear anatomic knowledge of the operation is still in short supply.After transfered, the hair of the scalp flap keep original characteristics, the patients must trim everyday. Epidermal growth factor (EGF) can inhibited the growth of hair follicie. The transport of drugs through the skin is greatly limited by the permeation characteristics of the stratum corneum, which is regarded as the main barrier for transcutaneous transport. Therefore, when poorly penetrating Pharmaceuticals are bound to lipid structures such as nano-liposomes, they can enter the skin in higher amounts. By using this carrier system, even high molecular... |
