Histochemical Study on Glycogen Metabolism in Psoriasis Vulgaris

In vivo study of skin mechanical properties in psoriasis vulgaris.

The aim of this study was to investigate the mechanical properties of the skin in psoriatic plaques before and after treatment with dithranol and in clinically uninvolved psoriatic skin in comparison with the skin of healthy controls. In total, 82 psoriatic plaques in 19 in-patients and 51 age-matched control subjects were studied with a non-invasive suction device (Cutometer). The plaques were...

On Artifacts Appearing in the Histochemical Fixation of Glycogen

1. Fixation artifacts associated with glycogen translocation are prevalent in tissues of parenchymatous type and scarce or non-existent in tissues of loose type. 2. Liver tissue treated with M/3 NaOH solution before fixation did not show an uneven distribution of glycogen. This was interpreted as indicating that the liver, a tissue of parenchymatous type, was changed, so to speak, into a loose ...

Histochemical demonstration of glycogen synthesis in vitro.

[Nail psoriasis in individuals with psoriasis vulgaris: a study of 661 patients].

BACKGROUND AND OBJECTIVES The nails are affected in a substantial number of patients with psoriasis. Nevertheless, few epidemiological studies have reported the characteristics of patients with nail psoriasis. Here we describe the epidemiology of nail psoriasis and the main characteristics of affected patients. PATIENTS AND METHODS We undertook a prospective case-control study at Hospital Uni...

Myasthenia gravis and psoriasis vulgaris.

Myasthenia gravis is a rare autoimmune disorder in which antibodies form against acetylcholine nicotinic postsynaptic receptors at the myoneural junction. Psoriasis vulgaris is a chronic, recurring, and an inflammatory skin disease. Myasthenia gravis and psoriasis are both autoimmune diseases and correlated with specific human histocompatibility antigens. In this report, a 53-year-old woman who...
