Dynamics of T- and B-lymphocytes in the infectious process according to quantitative cytochemical findings]

Cytophotometric analysis with the use of autologous erythrocytes showed that T lymphocytes had the lowest RNA content and poorly differentiated lymphocytes had the highest RNA content, while in B cells an intermediate RNA level was observed, thus, the relative content of RNA could indicate to which particular system different peripheral blood cells belonged. In active infectious process, irrespective of the etiology of the disease, a decrease in both relative and absolute amounts of T lymphocytes and an increase in the amounts of poorly differentiated and B lymphocytes were observed.     

Functional reconstruction of both hands by free transfer of combined second and third toes from both feet

The correction of severe trauma to both hands by two major microsurgical operations and additional minor interventions on the already functioning transplants is described. The excision of combined second and third toes as transplants inflicts an injury on the foot, but for our patient this iatrogenic trauma was justified. Careful investigation of the feet after transfer shows that their condition does not significantly impair the quality of the patient's life. The special importance of the patient's desire to regain his or her abilities and to collaborate with the medical staff is emphasized.     

The action of laser radiation on the phosphoinositide cycle and calcium absorption in the squid neural trunk

The content of polyphosphoinositides and phosphatidic acid increases in the squid axon under the action of laser radiation and the content of monophosphoinsitide decreases. At the same time the absorption of calcium ions by axon decreases. It is suggested that the laser radiation intensifies the synthesis of polyphosphoinositides and inhibits the system responsible for their degradation as well causes the desorption of the surface-bound calcium.
