The Influence of prolonged beta-blockers treatment on male rabbit's sexual behavior and penile microcirculation.

The aim of the study was to assess the effect of the prolonged intake of three beta-blocking drugs (propranolol, metoprolol and nebivolol) on the sexual behavior and penile microcirculation of rabbits. Drugs were administered p.o.

Photodynamic therapy of head and neck tumors and non-tumor like disorders.

In conclusion, we would like to emphasize that photodynamic therapy can be used as a convenient and promising tool in the treatment of various malignancies in the head and neck area. It has to be stressed that PDT is still less effective in the treatment of more advanced cases of head and neck cancer. As the method of treatment which improves the quality of life, its usefulness can be considered as well as palliative treatment of non-operative cases.

Determination of basic fibroblast growth factor levels in serum of tumor-bearing BALB/c mice treated with photodynamic therapy.

In the present study we have checked whether photodynamic therapy (PDT) may influence concentration of basic Fibroblast Growth Factor (bFGF) in in vivo conditions. We have implanted malignant tumor, i.e.

The combined treatment of transplantable solid mammary carcinoma in Wistar rats by use of photodynamic therapy and cysteine proteinase inhibitor.

Numerous studies have shown that lysosomal proteinases play an important role in carcinogenesis. The enzymatic activity of tumor-associated proteases is counter-balanced by specific inhibitors. Photodynamic therapy (PDT) is a technique which involves photoexcitation of sensitizing drugs retained in neoplastic tissue that is subsequently destroyed.

[Clinical applications of photodynamic therapy in the treatment of laryngeal lesions].

Photodynamic therapy (PDT) has been used in the treatment of laryngeal lesions. The disorders comprised primary dysplasia and leukoplakia of the vocal cords. The patients after diagnosis were subjected to the therapy.
