Fig. 1. Schematic of the cross section of a mammal s skin. The relative size and function of the parts depend on the species and breed of the animal. For goats, where the wool or hair is sparse because it is not needed for warmth, the skin is dense to provide protection for sheep protected primarily by heavy wool, the skin contains more oil (sebaceous) glands to lubricate the wool for catde, both the hair and the heavy hide stmcture protect the animal (3).

Sheep and fur animals are protected primarily by their wool or hair. The fiber stmcture of the skin is very fine and has less strength than calfskin or other nonfur mammals. The sheepskin has a high concentration of hair foUicles and sebaceous glands. When taimed the fur skin has an open stmcture, is soft, and lacks strength relative to many other leathers. [Pg.81]

Plasma levels of 3—5 p.g/mL are obtained two hours after adraiinistration of 200 mg ketoconazole. No accumulation in the bloodstream was noted after a 30-wk treatment with this dose. The half-life is approximately eight hours. When ketoconazole is taken with meals, higher plasma levels are obtained. Distribution studies using radioactive ketoconazole in rats show radioactivity mainly in the Hver and the connective tissue. Radioactivity is also present in the subcutaneous tissue and the sebaceous glands. After one dose of 200 mg in humans, ketoconazole is found in urine, saUva, sebum, and cenimen. Like miconazole, the mode of action is based on inhibition of the cytochrome P-450 dependent biosynthesis of ergosterol. This results in disturbed membrane permeabiUty and membrane-bound enzymes (8,10,23,25). [Pg.256]

Chemical Acne Many chemical compounds induce skin lesions that are similar to acne. Oils, tar, creosote, and several cosmetic products induce chemical acne. These compounds induce keratinization of the sebaceous glands of the skin, obstruction of the glands, and formation of acne. Chloracne is a specific skin lesion that is induced by chemical compounds that are structurally similar to 2,5,7,8-tet-rachloro dibenzo-p-dioxin (TCDD). Chloracne is slow to heal and difficult to... [Pg.307]

Lanolin is a wax made in the sebaceous glands of sheep and washed out of wool with detergents. It is used in many hair- and skin-care products. [Pg.62]

Susceptibility to acne is also due to genetic factors. It does not follow Mendelian rules however, if both parents had severe acne when adolescents, their children are likely to present with clinical acne in puberty. Genetic factors play an important role in determining the size and the activity of sebaceous glands, while exogenous factors such as colonization of P acnes modulate the clinical expression of acne. Racial differences also exist. Caucasians are more prone to severe acne than black people. [Pg.114]

The pilosebaceous unit of the skin consists of a hair follicle and the surrounding sebaceous glands. An initial acne lesion called a comedo forms when there is a blockage in the pilosebaceous unit.8... [Pg.960]

Sebum is released by the sebaceous glands and naturally maintains hair and skin hydration. An increase in androgen levels, especially during puberty, can cause an increase in the size of the sebaceous gland and the production of abnormally high levels of sebum within those glands. This excess sebum can result in plugged follicles and acne formation. [Pg.960]

Lanolin is a wax secreted by the sebaceous glands of sheep it is obtained from wool and it has been used as a lubricant and as an ingredient in pharmaceutical preparations. It contains esters of long chain alkanoic acids, both linear and branched, and of hydroxya-cids, cholesterol and lanosterol [2,83]. [Pg.11]

Skin appendages can be distinguished into hair follicles with their associated sebaceous glands, eccrine sweat glands, apocrine sweat glands, and nails. [Pg.6]
