In F1 and F2 from a cross between two clones of Dileptus anser isolated from natural sources (MT 1 x x MT III; MT = mating type), along with "normal" clones, many clones were observed demonstrating abnormal phenotype with respect to the MT-character. Irregular features of the latter were as follows: a) a delay in maturation; b) temporary reversion to(More)
Calcium-sensitive forms of adenylyl cyclase (AC) were revealed in most vertebrates and invertebrates and also in some unicellular organisms, in particular ciliates. We have shown for the first time that calcium cations influence the AC activity of ciliate Tetrahymena pyriformis. These cations at the concentrations of 0.2-20 microM stimulated the enzyme(More)
Two clones of Dileptus anser, originally isolated from natural reservoirs and referred to below as B and D clones, were found to display different serotypes, when cultured under identical laboratory conditions. On being tested with two different polyclonal rabbit immune sera against each particular clone (the classic immobilization test) these clones showed(More)
The authors characterize signs of the spread of carcinoma of the esophagus to the neighboring and remote structures, which were revealed by computerized+ tomography. The value of the method in identifying the stage of esophageal carcinoma is discussed. It is shown that the complex of signs must be taken into account in determining growth of the tumor into(More)
From analysis of the results of scrupulous examination of 66 patients with pathological shadows up to 3 cm in diameter found in the lungs during X-ray examination the authors established that peripheral carcinoma of the lung accounts for 65.2% of all asymptomatic accidentally revealed structures in the lungs. Computerized tomography is a valuable method of(More)
Hybridological analysis of mating types (MTs) has been first made for the lower ciliate Dileptus anser. Clones of an initially unknown genotype belonging to three MTs (MT I, MT II and MT III), characteristic of D. anser, were isolated from natural reservoirs and further used for crosses. In one group crosses, synclonal inheritance and typical Mendelian(More)
Fifty-one patients with stenosis of the upper portion of the tracheobronchial tree of various origins were examined; the sensitivity of computer-aided tomography (CAT) in the diagnosis of stenoses of the trachea and the main bronchi was found to be 95.83%, specificity 98.31%, and accuracy 93.87%. CAT is superior to other methods of investigation (common(More)
The results of a 10-year follow-up of 101 patients with pyothorax that developed after operations on the lungs, bronchi, and trachea (5.4% of all patients who underwent operation) show a stable fever of 38 degrees C and higher, pain in the chest, leucocytosis, and a shift of the peripheral blood leucocyte count to the left to be the most constant clinical(More)
A total of 104 patients with tumors of the upper portions of the tracheobronchial tree were examined. The tumors were malignant in 66 cases (53 primary and 13 secondary ones) and benign in 38 cases. The sensitivity of CT in the diagnosis of blastomas of the trachea and the main bronchi made up 96.12%, specificity 86.15%, and accuracy 91.6%. CT permitted the(More)
