Epidermal sliding

Pure white frosting (Figure 14.9), gradual disappearance of epidermal sliding the TCA has reached the reticular dermis ... 

ETCA can be applied as a peel to the papillary dermis, when a sufficient number of coats are gradually applied to produce even pink-white frosting and epidermal sliding . The protocol developed to treat stretch marks has sometimes also been used successfully for facial rejuvenation. 

If the frosting on the melasma is pink and even, with some epidermal sliding, the ETCA solution should not be applied there again. 

Epidermal sliding this appears when the skin is pinched after a peel to the papillary dermis. 

When the skin around the keratosis turns pink-white, it means that a sufficient number of coats has been applied. When the skin on the scalp is pinched between two fingers and epidermal sliding occurs (Figure 18.2), the papillary... 

Epidermal sliding is easy to recognize, as the dermal and epidermal proteins have been coagulated by the TCA. The ETCA solution should not be neutralized or removed. It... 

The solution is applied to the whole face and left to dry. Additional coats are applied to achieve an even pink-white frosting and signs of epidermal sliding. The post-peel mask cream after the peel, is applied to the whole face. 

Ideally, the patient has taken an analgesic (paracetamol plus codeine). The peel solution is applied to each cosmetic half-unit (e.g. half of the forehead) until even pink-white frosting and epidermal sliding occur (Figure 23.8), all the time making the best use of cryoanesthesia and vocal anesthesia. The post-peel cream soon alleviates the pain caused by the acid, and it is possible to do a peel to the papillary dermis without anesthesia. 

Occasionally, small, buff-yellow patches may appear. Epidermal sliding is soon replaced by edema. 

Epidermal sliding the acids coagulate the proteins that bind the epidermis to the dermis and the epidermis slides over the dermis. Sliding is the pathognomonic sign of a peel to the papElary dermis. 

Figure 11.2 The epidermal sliding sign. When slight tension is placed on the skin an exaggerated amount of wrinkling occurs. This indicates that the peel has entered the papillary dermis level but has not coagulated enough proteins for the epidermis to become adherent to the papillary dermis...

Continued application of acid wiU result in vasospasm of the capillary loops in the papillary dermis. Blood flow to the area will cease, and the pink sign will disappear. The frost will appear as a solid white sheet (absence of the pink sign Fig. ii.i). This is the endpoint for a superficial reticular dermis peel. The loss of the pink sign implies that the entire papillary dermis is involved and the upper reticular dermis has been reached but not penetrated. In darker-skinned individuals, the pink sign may be difficult to visualized, thereby epidermal sliding must be used instead to gauge depth. 

Epithelial tissue in specimen, negative control tissue, positive control tissue and negative reagent control slides. Staining is moderate to marked, especially in epidermal epithelium. Background in epithelia accompanies background in connective tissue. 

While the use of water alone can soften hair, the addition of a fatty acid salt (i.e., soap) improves the performance of water as a shaving aid by creating a film on the skin. This film created by shaving soaps allows the blade to slide with decreased resistance along the outer epidermal skin surface without cutting into the vascular (blood vessel-possessing) deeper dermal skin layer. In general, soap results from the treatment of... 

Initial fluorescence scans on epidermal strip guard cell chloroplasts in a single stomate were made using the SpectraCube 1000 system [5] after which NO treated and untreated strips were photographed (Fuji ASA/100 - color film) by an Olympus-Vanox AH-3 Fluorescent Microscope - excitation wavelength -410-490 nm, emission - 669 nm, exposure time - 18 sec. Developed color slides were subsequently scanned with a computer-linked adapted Li-Cor Spectroradiometer Model 18 00, which enabled quantitative composite fluorescence readings at 669 nm.
