[The hygienic protective area of the Kaliakra Medium-Wave Radio Station]. / Khigienno-zashtitna zona na obekt "SV radiostantsiia--Kaliakra".

A polemics on the ecological expedience of the transmitting station "Kaliakra", which is in the process of building, was held. The two opposing sides in the diaput are OOD "Bulgarian Posts and Power-line Communication" and the community of village Balgarevo, district of Varna. The ecological aspect of the project is very well known in the Ministry of the Environment and the Ministry of Public Health, as well as in the National Center of Hygiene, Medical Ecology and Nutrition. The latter has given an expert attitude for the hazardous zones around the site. As a result of this polemics is the delay of the building, i.e. blocking investments and missed opportunities, because of not realized exploitation. Stating the above we would like to expand the competent forum of the engaged in the problem. For this purpose we are ready to discuss with the participants in the Conference the methods and results of the calculations, as well as the normative basis, which were used in determining the hazardous zone. The control calculations point out, that the level of the electromagnetic exposure of the population in the district will be lower than the allowable values, which are given both in the Bulgarian State Standards and the foreign standard documents for hygiene control of nonionizing radiation.

[The Clinitron fluidized bed--its qualities and use]. / Fluidnoto leglo "Klinitron"--kachestva i prilozhenie.

The basic properties and characteristic features of a unique therapeutic device--the "Clinitron" fluid bed--are described. Regardless of its comparatively late adoption in the clinic practice of this country, it is successfully used in the management of severe burns at the burn lesion department in the town of Plovdiv. Emphasis is laid on the many-sided qualities of Clinitron-therapy, practicable in the various fields of surgery.

[The parascapular fasciocutaneous flap in the surgical treatment of deep burns in the axillary area]. / Paraskapularno fastsiokutanno lambo pri khirurgichno lechenie na dulboki izgarianiia v oblastta na aksilata.

An original operative approach to severe defects of the axilla--periscapular fasciocutaneous flap according to Pontaine--is recommended. It is a matter of a procedure which surgeons dealing with the problems of plastic and reconstructive surgery become acquainted with for the first time. A classification of axillary defects, contributing to the most adequate choice of operative approach, is also suggested. Typical cases where this operative method is used are illustrated.

[The treatment of extensive burns using a primary biological dressing in the Clinitron fluidized bed]. / Lechenie na obshirni izgarianiia posredstvom purvichna biologichna prevruzka v usloviia na fluidno leglo "Klinitron".

The treatment of extensive burns using a method recently adopted in this country, namely application of primary biological dressing in patients undergoing treatment under conditions of "Clinitron" fluid bed, is discussed. The ten-year follow-up study covers 1100 patients with extensive burns, distributed in three groups according to the method of local treatment employed: 1) Patients treated by closed method in conventional conditions. 2) Patients treated by closed method under fluid bed conditions. 3) Patients treated on a fluid bed plus primary dressing with the newly obtained biopreparations for local application--Cypocol and skin collagen transplant. The approach outlined is consistent with the traditional treatment procedures. By combining the curative properties of biopreparations, used as primary biological dressing, with those of the fluid bed, a clinical effect considerably superior over the one thus far recorded is attained. Emphasis is laid on the advantages of the therapeutic approach proposed-suppressing endo-and exogenous infections, and substantial reduction of the hospitalization term.

[The advantage of biological explants in covering donor areas]. / Predimstvo na biologichnite eksplanti pri pokrivane na donorni zoni.

A new method of treating raw donor wounds by biological resurfacing in conjunction with fluid bed is described. The classical method of donor area treatment and the newly developed procedure are comparatively studied. Inferences are reached warranting recommendation of the new approach as a routine method for operative management of patients with extensive burns, and all cases where free skin grafting is used as well.
