[Is the vascular-endothelial growth factor responsible for the malignancy of lung cancer?].

Lung cancer is the most common malignancy in the world. Its large ability to regional extension of the tumor and formation of local and distant metastases causes that the number of deaths and cases of disease are almost identical. The reason of this ability lies in the creation process of blood vessels that is angiogenesis, which main stimulus is the vascular-endothelial growth factor (VEGF).

[Nodular lymphoid hyperplasia - a rare case of lymphoproliferative disorder of the lungs].

Nodular lymphoid hyperplasia (NLH) belongs to a very rare, mild, lymphoproliferative disease of unestablished aetiology historically included in the group of pseudolymphomas. Its existence was controversial for many years, until modern techniques of pathomorphological diagnosis approved it as a separate entity of lung disease. It manifests in the form of well limited nodules localized in the lungs, which are mostly identified accidentally.

Comparative study of selected blood biochemical components in milk or milk-replacer fed calves during the second week of life.

The experiment was carried out on 13 male Polish Black and White dairy calves of 75% share of the Holstein-Friesian (HF) breed during the second week of life. The animals were divided into two groups. One group (n=7) was fed mother's milk and the second (n=6) milk replacer.

Prognosis and survival after radical resection of primary adenosquamous lung carcinoma.

Objective: In order to evaluate the follow-up study of surgical treatment for primary adenosquamous lung carcinoma (ASC) we specified prognostic criteria, also in comparison with primary adenocarcinoma (AC).

Methods: The study group consisted of 96 patients discharged between 1990 and 1999 after radical surgical treatment for ASC-80 (83%) men and 16 (17%) women aged 34-73, mean 56 years. Consequently, we evaluated 252 patients operated during the same time period for primary AC.

Benign clear-cell "sugar" tumor of the lung--a case report.

The authors present a rare case of a surgically treated so-called "sugar" tumor of the lung in a 68-year old male patient.

Alveolar adenoma of the lung--a report of two cases.

The authors present two cases of an extremely rare alveolar adenoma of the lung in a 64-year old female and a 45-year old male surgical patients. The report is the first description of such a tumor in the Polish literature.

Primary pulmonary Hodgkin's lymphoma with Epstein-Barr and cytomegaly virus infections. A case report and differential diagnosis.

We report a rare case of primary pulmonary Hodgkin's lymphoma associated with Epstein-Barr virus (EBV) and cytomegaly virus (CMV) infections as demonstrated by in situ hybridisation method. Reed-Sternberg cells were CD30 positive. Numerous CD15+ cells were noticed, some of them with concomitant CMV infection.

Pulmonary langerhans cell granulomatosis. A study of 11 cases.

This report based on 11 cases of pulmonary Langerhans cell granulomatosis describes the histological features of this condition and presents results of discourse about its character.

Silicoproteinosis of the lung in a 49-year-old man.

We report a rare case of silicosis, histologically corresponding to silicoproteinosis and tuberculosis, in a man working consecutively as a miner, blacksmith and founder. A microscopic study revealed deposits in alveoli, in which immunohistochemistry did not reveal surfactant (SP-A), that was present in the alveolar fluid in alveolar lipoproteinosis.
