[Mechanisms of immune suppression of systemic inflammation by the action of the narrowband ultraviolet B (311 nm) therapy in patients with psoriasis].

In patients with psoriasis, there is increased secretion of serum cytokine IL-22 of CD4 T helper 17/22 types and pro-inflammatory mediators (IL-6, TNF-alpha). Narrowband UVB therapy during 12 weeks significantly reduced the levels of IL-6, TNF-alpha IL-22 compared to the standard treatment. Patients who are resistant to narrow band UVB therapy, the use of erythmogenic strategy leads to increase of immunosuppressive effects on systemic inflammation than suberythmogenic one.

[About the state of iron in biological systems].

The magnetic properties of albumen systems of plant and animal origin (more than 150) have been investigated by Mossbauer spectroscopy, magnetometry, and (in control experiments) X-ray diffractometry. It was found that characteristic of the process of iron accumubation in albumen systems is the tendency to form structure units based on iron oxyhydroxides and to form regions of magnetic ordering.

[Mossbauer data on the effect of NAD.H on the state of iron in bacteria].

The state of Fe of bacterial cultures of different systematic positions (Bacillus megaterium, Bacillus polymyxa, Pseudomonas putida, Pseudomonas fluorescens, Alcaligenes faecalis, Arthrobacter siderocapsulatus) grown on the medium containing Fe(III) citrate (up to 100 mg/l) with additional or without NAD.H was studied. The samples were in damp air-dry, second moistened, dried at 383 K states.
