[Taxan induction chemotherapy and concomitant chemoradiotherapy with cisplatin in patients with locally advanced head and neck cancer--early results].

Unlabelled: The growing number of patients with head and neck cancer is a reason to search for new effective treatment strategies. Results of treatment for locally advanced squamous cell head and neck cancer with surgery and/or radiotherapy are still unsatisfactory. During last decade concomitant chemoradiotherapy became a new standard in this group of patients.

[B-cell lymphoma of the nose cavity--case report].

Introduction: Non-Hodgkin's lymphoma of the nose and sinuses accounts for 5,8-8% of the tumors in that localisation. Large B-cell lymphoma (DLBCL) are frequent in mediastinum, nasopharynx, stomach and retroperitoneal space. On rare occasions it presents with extracutaneous dissemination.

[Proteases of neutrophilic granulocytes].

The literature referring to proteolytic enzymes of neutrophilic granulocytes was surveyed. Biosynthesis, subcellular distribution, division according to the catalytic site structure, inhibitors and methods used to determine the activity of these enzymes were discussed. The survey included metaloproteases (granulocytic collagenase, gelatinase B), serine proteases (granulocytic elastase, cathepsin G, protease 3), membraneous proteases (aminopeptidase N, aminopeptidase P, neprilisine), cysteine and aspartic cathepsins.
