[The effect of actinomycin D on electroencephalographic activity in the rabbit brain]. / Uticaj aktinomicina D na elektroencefalografsku aktivnost mozga kunica.

DNA, RNA and cellular proteins are of great importance in regard to the following processes: learning, memorizing and storage of memory. That is why protein synthesis blockers are successfully used in investigations of these brain functions. Aktinomicin D (AMD) is such a substance; it is an antibiotic which is used in treatment of some malignant diseases, but on cellular level it disturbs RNA synthesis. Experiments were carried out on Chinchilla rabbits with chronically implanted electrodes for registration of electroencephalographic activity. Intracerebroventricularly applicated Aktinomicin D disturbs the appearance of habituation after rhythmic repetition of electrocutaneous stimulation of the same characteristics which clearly points to the importance of preserved cellular protein synthesis in the processes of learning.

[Nervous system plasticity in the recovery of patients after cerebrovascular stroke]. / Plasticnost nervnog sistema u oporavku bolesnika nakon cerebrovaskularnog insulta.

Plasticity is a very important characteristic of the nervous system structures, due to which it alliterates the functioning way, recompenses deranged function and adapts to new conditions caused by damage. Deranged brain circulation is very frequently caused by the arteriosclerosis which can finally cause stroke. Stroke usually appears at the age of 60-69 years, but in persons of different ages as well. The aim of rehabilitation is to ensure quality of life as much as possible. In young persons recovery after stroke is usually successful, whereas the plasticity of the nervous system is completely preserved.

[Therapy of venous ulcers using pulsating electromagnetic fields--personal results]. / Terapija venskih ulkusa pulzirajucim elektromagnetnim poljem--nasi rezultati.

The authors review the results of the treatment of venous varices by a pulsating electromagnetic field (PEMF), by the use of IVEMT-2 apparatus, treated at the Department of Dermatovenereology in Novi Sad and the Institute of Medical Rehabilitation. The treatment was carried out in 18 patients--5 men and 13 women, mean age 56 years, all with venous varices of post-thrombophlebitic origin. The number of sessions within the PEMF treatment was 10 per patient, each session lasting 15 min. The results were followed by measuring the varix surface prior to and after the treatment. The number of varices prior to the therapy was 26 and after the treatment was 20. The total surface of the varices before the treatment was 55183.90 mm2, the mean surface being 2122.46 mm2. After the treatment 6 varices epithelialized, while the total surface was 36902.51 mm2. The mean surface of the varices following the treatment was 1845.13 mm2. The varix surface reduction rate following the treatment was 33.13%. Considering the number of patients, the obtained results are preliminary and they reflect the benefits of PEMF for epithelialization of venous varices.
