Effect of 1,25-dihydroxyvitamin D3 on adenylate cyclase and protein kinase C in pig epidermis.
Koizumi H, Yasui C, Ohkawara A
1,25-dihydroxyvitamin D3 (1,25(OH)2D3) is suggested to be involved in the regulation of keratinocyte proliferation and differentiation. Recent evidence also indicates its potential value for the treatment of psoriasis, where the alteration of various transmembrane signalling systems has been well documented. Using porcine epidermis, we investigated the effect of 1,25(OH)2D3 on adenylate cyclase an ...

UV-induced squamous cell carcinomas in the hairless mouse. Morphological characteristics and transplantation in the syngenic and nude mouse.
Cadi R, Beani JC, Jacrot M, Pinel N, Amblard P
Squamous cell carcinomas were induced by UVB in the hairless mouse HRO hr/hr. Twelve mice were irradiated three times a week at a dose of 0.19 J/cm2. The average latency period for the appearance of the first tumour is 16 weeks and by the 21st week, tumour incidence is 100%. Further observation of these tumours shows that their growth is independent of irradiation dose and that the tumours continu ...

Topical salicylic acid interferes with UVB therapy for psoriasis.
Kristensen B, Kristensen O
Salicylic acid has been widely used in the topical treatment of psoriasis. Chemically it is closely related to paraaminobenzoic acid. Following in vitro studies indicating that salicylic acid might exhibit relevant UVB absorption, we found that salicylic acid had a clinically pronounced filter effect when applied prior to UVB exposure. The duration of photoprotection after application was more tha ...

Effect of retinoic acid on the infiltration of murine melanoma cells into the type I collagen gel.
Kono T, Furukawa M, Tanii T, Taniguchi S, Mizuno N, Ishii M, Hamada T
Two lines of murine melanoma cells (B16 and Cloudman S91) were cultured on type I collagen gel and the effects of all-trans-retinoic acid on the growth and infiltration into the gel were assayed. In both lines, proliferation and the degree of infiltration were suppressed by the addition of all-trans-retinoic acid. The infiltration-inhibiting effect was expressed very rapidly and was dose-dependent ...

Dose and timing studies for the optimization of contact sensitivity in the mouse.
Brown WR, Shivji GM
We investigated the effectiveness of very low doses of the contact sensitizer dinitrofluorobenzene in sensitizing BALB/cJ mice. Surprisingly, the ear swelling reactions were greater with lower dinitrofluorobenzene doses, down to one-twentieth of doses commonly used. Although it is common practice to use much lower doses at challenge than at sensitization, we found greater reactions with lower dose ...

Expression of intercellular adhesion molecule-1 (ICAM-1) in benign naevi and malignant melanomas.
Hansen NL, Ralfkiaer E, Hou-Jensen K, Thomsen K, Drzewiecki KT, Rothlein R, Vejlsgaard GL
Intercellular adhesion molecule-1 (ICAM-1) is a membrane-bound glycoprotein that is a ligand for lymphocyte function-associated antigen-1 (LFA-1) and is important for a number of cell adhesions in immune reactions. The molecule is expressed by several cell types (e.g. macrophages, endothelial cells, keratinocytes, melanoma cells and cell lines) and there are some indications that expression of thi ...

Factor XIII-deficiency in the blood of venous leg ulcer patients.
Vanscheidt W, Hasler K, Wokalek H, Niedner R, Schöpf E
Pericapillary fibrin cuffs are probably involved in the pathogenesis of venous leg ulcers. Factor XIII (Fibrin stabilizing factor) is of importance in wound healing. Its activity, which may affect ulceration, was found to be significantly reduced in the blood of venous leg ulcer patients and in post-phlebitic patients, compared with healthy controls.

Lipophagic panniculitis in re-excision specimens.
Zelickson BD, Winkelmann RK
Lipophagic panniculitis consists of a macrophage infiltrate in the subcutaneous tissue. The macrophages transform into foam cells within the panniculus; they replace lipocytes and may form giant cells. Although those pathologic features have been described as diagnostic of Weber-Christian disease, we report the occurrence of lipophagic panniculitis in re-excision specimens. Among 252 re-excision s ...

Re-evaluation of the pathergy test in Behçet's disease.
Ozarmagan G, Saylan T, Azizlerli G, Ovül C, Aksungur VL
A positive pathergy test in patients with Behçet's disease has been accepted as a diagnostic criterion by many authors, but in recent years it has been claimed that the test has a decreased positivity. We have examined the test in 92 proven cases of Behçet's disease, using 20G and 26G disposable needles and evaluated them after 48 h. Maximum positivity was found to be 65% when we used needles of ...
