E rosettes in the uranium miners with lung cancer.

Rosette forming cells (RFC) were evaluated in the peripheral blood of healthy persons, patients with lung cancer and chronic bronchitis. Simultaneously the levels of RFC in persons with and without radiation exposure were compared. Two types of rosettes were enumerated: 1) lymphocytes binding 1 or 2 sheep red blood cells (SRBC), 2) lymphocytes binding 3 or more SRBC. Then the sum of both types was calculated. The patients with lung cancer were divided according to the TNM classification and histological types. The relative and absolute numbers of RFC in 1 microliter of peripheral blood proved depressed capacity of peripheral T-lymphocytes to form rosettes not only in patients with cancer or chronic bronchitis but also in controls with radiation exposure. Furthermore, there was established that the control group with radiation exposure was not different from the patients with cancer or chronic bronchitis.

The occurence of collagen type II in bronchogenic carcinoma.

It has been evidenced in a single case of bronchogenic carcinoma, that the proportion of collagen type II is increased in the diseased tissue. During the experimental work the collagenous stroma was isolated, subjected to cyanogen bromide cleavage and the relative proportion of individual types of collagen was judged according to the occurence of alpha1(I)CB3 and alpha1 (II)CB3 peptides. The nature of these peptides was proved by the chromatographic behavior during CM-cellulose chromatography, Ultrogel AcA 54 separation and by their amino acid composition.
