Peat therapy has been used in Continental Europe with good results to treat rheumatic diseases, rheumatoid arthritis in particular, and also gynaecological and urological ailments. Peat preparations have also been used in the treatment of eye diseases and diseases caused by the Herpes virus. Peat balneology is studied in numerous balneological research institutes where minerals waters are also investigated. The physicochemical properties of peat are determined. The most important parameter to be taken into account when selecting bath peat appears to be the degree of decomposition. The degree recommended for Sphagnum peat is H6 — H8 and for Carex peat H8 — H10 measured on the von Post scale. The mean degree of decomposition of the bath peat used in the German Democratic Republic fluctuates, however, between H5 and H7 . The curative power of peat therapy is attributed to the thermophysical properties of peat, which allow the human body to become overheated, and to the special properties of the biologically active substances in the peat. Key words: peat, medical geology, balneology.

A short review on biologically active substances in peat and their characterization is given. There is a clear need for further multidisciplinary research into use of peat as a chemical raw material. The material is based on a lecture presented at DGMT symposium "Operating Mechanisms of Peat Therapy" in Bad Alexandersbad, FRG, 1985. Key words: peat therapy, biologically active substances, mode of action at the molecular level

The short-terms effects of wood ash and NPK fertilizer on the population of Enchytraeidae worms in a drained spruce swamp and pine bog were studied. Both NPK fertilizer (300 kg/ha) and ash (3000 kg/ha) treatments reduced worm numbers at both sites, but the effects were slight compared to seasonal fluctuations. Temporal fluctuations in worm numbers were relatively smaller at the pine bog than at the spruce swamp. NPK fertilizer temporarily changed the relative vertical distribution while tha ash treatment did not. The effects upon worm biomass and respiration rate were similar as those for worm numbers . Key words: Enchytraeidae, NPK fertilization, ash fertilization, drained peatlands

English title: Two microscopic methods for the determination of peat types.

Preparation of peat samples, identification of tissues and estimation of constituents are important in microscopic determination of peat type. Two microscopic methods for determining peat type are described: a wet sieving method and a drying, pulverizing and KOH solution method. The wet sieving method does not involve a tissue-destroying base or acid treatment. In both methods slides are prepared from the peat suspension by pipetting and drying. The tissues are then identified under a microscope and checked by reference to literature and a slide collection. The amount of peat factors is estimated by the point frequency method. The wet sieving method is simpler and gives a higher proportion of better preserved tissues, making tissue identification more reliable. Key words: peat type, epidermic tissues, wet sieving, point frequency method, microscopy.
