An inhibitor of papain and other SH-proteases was purified 520-fold from human epidermis extracts by acetone fractionation, heat treatment, papain-Sepharose affinity chromatography, and Sephadex G-50 chromatography. The purified inhibitor had a molecular weight of 12,600 and contained no hexose, as tested by the anthrone reaction. The inhibitor survived in a boiling water bath, in 5% trichloroacetic acid, 20 mM Na3PO4 (pH 12.1) and 4 M NH4OH (pH 11.9). By isoelectric focusing 2 major activity peaks with pI's of 4.6 and 4.8, and a minor peak with a pI of 4.9 was fractioned, and 3 corresponding protein bands were seen after analytical isoelectric focusing. Immunization of rabbits with the purified inhibitor yielded a highly specific anti-inhibitor serum. The purified inhibitor inhibited papain, ficin, human cathepsins B and C, and slightly inhibited bromelain. No inhibition of serine proteases (bovine trypsin and chymotrypsin A, porcine elastase) or an acid protease (human cathepsin D) was observed. Evidence was obtained that the inhibitor formed a complex with both dithiothreitol-activated papain and enzymatically inactive mercuripapain.

gamma-Glutamyl transpeptidase (GGT) was extracted from squamous cell carcinoma tissues of human skin (SCC) by Triton X-100 and bromelain treatment, and some of its biochemical properties were compared with those of GGT extracted from eccrine gland-rich tissue and normal kidney. GGT activity significantly increased in SCC, but there was no definitive differences in enzymological properties between GGT of SCC and normal tissue enzyme. However, GGT of SCC was distinguishable from those of normal tissues by isoelectric point, electrophoretic mobility, and sensitivity to neuraminidase treatment. These results indicate that GGT of SCC has some variant properties which may be related to skin carcinogenesis.

During the last 10 to 15 years, complementary and alternative medicine (CAM) has become increasingly popular in the US. Within this realm of health care, oral and topical herbal supplements have become some of the most frequently used alternative therapies. Most herbal supplements are based on, or include, several botanical ingredients with long histories of traditional or folk medicine usage. Among the numerous botanical ingredients available on the market today, several are believed to confer dermatologic benefits. This article will focus on a select group of botanical compounds, many of which have long traditions in Asian medicine, with potential or exhibited dermatologic applications, including curcumin, Ginkgo biloba, ginseng, silymarin, soy, and tea tree oil. Other botanical agents, such as arnica, bromelain, chamomile, pomegranate, caffeine, green tea, licorice, and resveratrol, are also briefly considered. Some of these ingredients have been incorporated into topical formulations.

Complementary and alternative medicine (CAM) has become increasingly popular in the United States during the last 10-15 years. The use of oral and topical supplements falls within this framework. Most oral and topical supplements are based on or include several botanical ingredients, many of which have long histories of traditional or folk medicine usage. Several of the available products derived from botanical sources are touted for their dermatologic benefits. The focus in this discussion will be on a select group of botanical compounds that have been used for dermatologic purposes or show promise for such applications, including: rosemary, polypodium leucotomos, propolis, oatmeal, olive oil, grape seed extract, lavender, mushrooms, and coffeeberry. Other more commonly used products of botanical origin, such as arnica, bromelain, caffeine, chamomile, ferulic acid, feverfew, green tea, licorice, pomegranate, and resveratrol, are also briefly considered.

<p>Aging gracefully has taken on a whole new meaning over the past few decades as new aesthetic treatments have been developed and are becoming more sophisticated by the day. The aging process, which is exacerbated by chronic UV exposure, results in dyspigmentation, loss of skin laxity, precancerous and cancerous skin lesions, fat loss and redistribution, and bone resorption. Laser and light devices can be used to treat dyspigmentation, while neuromodulators and soft tissue fillers can be used for rhytides and revolumization. Newer procedures include using resorbable polyglycolide/L-lactide suspension sutures with bidirectional cones for mid face revolumization, deoxycholic acid injections for submental fat reduction, and radiofrequency energy. Certain over-the-counter products can increase the risk of postprocedure bruising, while arnica and bromelain may help decrease this risk. Dermatologists continue to be at the forefront of aesthetic treatments, ready and willing to help the aging population look and feel their best.</p> <p><em>J Drugs Dermatol. 2017;16(6 Suppl):s84-86.</em></p>.
