Secretion of urokinase and tissue-plasminogen activator by epidermal cells in the presence of psoriatic fibroblast-conditioned medium.
Horiuchi Y, Marshall JM, Cederholm-Williams SA, Ryan TJ.
The present study examined secretion of urokinase and tissue-plasminogen activator by epidermal cells in the presence of psoriatic or uninvolved skin fibroblast-conditioned medium. Using zymographic analyses, a 54kD lysis band and a small 110kD band derived from urokinase could be detected in the harvest fluid from keratinocytes treated with both psoriatic and uninvolved fibroblast-conditioned med ...

The hairless mouse model for assaying the atrophogenicity of topical corticosteroids.
Woodbury R, Kligman AM.
The daily application of corticosteroids for 18 days to the dorsal skin of hairless mice resulted in loss of volume of all the cutaneous compartments. The epidermis thinned, sebaceous glands regressed, dermal thickness was reduced, horn-filled cysts shrunk, subcutaneous fat disappeared, and regression of the muscular layer occurred. The magnitude of these changes correlated strongly with the accep ...

Expression of loricrin in skin disorders.
Juhlin L, Magnoldo T, Darmon M.
Loricrin, the major component of the cornified envelope, is normally expressed in the granular layer of epidermis during the last steps of keratinocyte differentiation. Using an antiloricrin antiserum (A8-73), an increased expression of this envelope precursor was found in some disorders of hyperorthokeratosis (ichthyosiform erythroderma; lichen ruber), but not in others (keratodermia ichthyosis v ...

Localized proliferative effect of preadipocytes on cultured human epidermal keratinocytes.
Miyashita M, Baba S, Suzuki H.
The effect of preadipocytes (ST 13) on cultured normal human epidermal keratinocytes (NHEK) was investigated. The growth of NHEK was accelerated with co-cultured ST 13 cells. This stimulative effect must have been localized around viable ST 13 cells, because neither the medium nor the surface conditioned by ST 13 or the ST 13 cell fragments showed any promotion of NHEK growth, and NHEK showed a co ...

Lifetime topical application of tretinoin to hairless mice.
Kligman LH, Mezick JA, Capetola RJ, Thorne EG.
The discovery that topical tretinoin can reverse some of the effects of photodamage may lead to its chronic application. Examination of long-term effects was of interest. Three groups of hairless mice (age 6-8 weeks) were treated dorsally with 1) tretinoin (0.025%), 2) cream vehicle, 3) sham treatment. Applications were 3 times weekly and continued for up to 2 years until all mice were sacrificed ...

Topical retinoic acid treatment of photoaged skin: its effects on hyaluronan distribution in epidermis and on hyaluronan and retinoic acid in suction blister fluid.
Lundin A, Berne B, Michaëlsson G.
Topical treatment with retinoic acid (tretinoin, vitamin A acid) has been reported to partly reverse signs of photodamage. To determine whether the histochemical distribution of hyaluronan (hyaluronic acid, HYA) in the epidermis and dermis and the amounts of HYA and retinoic acid in suction blister fluid were influenced by such topical treatment, 14 subjects healthy apart from moderate photodamage ...

Elemental changes in guinea pig epidermis at repeated exposure to sodium lauryl sulfate.
Lindberg M, Forslind B, Sagström S, Roomans GM.
Epidermal hyperplasia is the response of the epidermis to external harmful stimuli. The control and regulation of this hyperplasia is not completely understood. It has been proposed that changes in the cellular sodium/potassium ratio are of importance in the regulation of cell proliferation. To evaluate if such a change in the elemental content of epidermal cells can be one factor to consider at i ...

A dose-response study of irritant reactions to sodium lauryl sulphate in patients with seborrhoeic dermatitis and atopic eczema.
Cowley NC, Farr PM.
The susceptibility of the skin of patients with seborrhoeic dermatitis to surfactant irritation was investigated and compared to that of a group of normal subjects and patients with a history of atopic eczema. Responses to six concentrations of sodium lauryl sulphate (SLS), applied to forearm skin, were assessed clinically and measured by laser Doppler flowmetry. Analysis of dose-response curves s ...

Cyclosporin A responsive chronic severe vesicular hand eczema.
Petersen CS, Menné T.
A patient with an otherwise recalcitrant chronic vesicular hand eczema responded with a dramatical improvement within 2 weeks of cyclosporin A (CsA) therapy 5.0 mg/kg daily. The patient was still free of eczema in spite of reducing the CsA dose to 2.5 mg/kg daily. CsA therapy was finally stopped due to a moderate increase in blood pressure, resulting in rapid recurrence of the hand eczema. The cas ...

Folinic acid rescue used routinely in psoriatic patients with known methotrexate "sensitivity".
Hills RJ, Ive FA.
Many combinations of methotrexate and folic or folinic acid have been used to limit the side effects of methotrexate therapy in psoriasis or psoriatic arthropathy. Methotrexate inhibits the enzyme dihydrofolate reductase and prevents the formation of DNA and RNA. Folinic acid, the 5-formyl derivative of tetrahydrofolic acid, is the active form of folic acid. We have confirmed in 5 patients that co ...

Intertriginous drug eruption.
Wolf R, Brenner S, Krakowski A.
Presented are two patients who developed an unusual, and as yet unreported eruption due to amoxycillin. They exhibited an eruption confined to the intertriginous areas, which mimicked intertrigo. Although drug eruption can mimic a variety of idiopathic skin diseases, intertrigo is easily distinguished from drug eruption and has not been mentioned in the differential diagnosis of this reaction. It ...

Juvenile generalized pustular psoriasis in a pair of monozygotic twins presenting strikingly similar clinical courses.
Takematsu H, Rokugo M, Takahashi K, Tagami H.
We describe an exceptionally rare case of juvenile generalized pustular psoriasis noted in monozygotic twins who, after developing the disease on the same day (the 48th day after birth) continued to show strikingly similar clinical features of generalized pustular psoriasis for 7 years. Not even therapeutic intervention by tonsillectomy performed at age 4 years on one of the twins, which was expec ...
