Morphology of autolymphocytes used in the treatment of trophic ulcers in the setting of diabetic foot syndrome

Diabetic foot syndrome is one of the most often chronic and severe complications of diabetes mellitus. Method of local treat-ment of trophic ulcers and wounds in the setting of diabetic foot syndrome using autolymphocytes processed by leukinoferon was developed in the Institute of Clinical and Experimental Lymphology (Novossibirsk). Autolymphocytes were obtained by lymphocytapheresis on the blood cell separator «Haemonetics MCS+». The study of ultrastructural organization of identified lym-phocytes processed by leukinoferon did not reveal any disturbances of their structural integrity. Numerical density free polysomal ribosomes increased by 50%. Volumetric density of vesicular structures in cytoplasm of lymphocytes increased by 3 times. Number of excrescences and microvilli formed by plasmatic membrane increased by 2,4 times. Thus, technologies of autolymphocytes iden-tification do not result to damaged structure of cells. Processing of the lymphocytes by leukinoferon does not cause cellular damage but promotes development of structural changes.

Effect of chronic restraint stress on dendritic spines and excrescences of hippocampal CA3 pyramidal neurons—a quantitative study

Effect of chronic restraint stress on the number of dendritic spines and excrescences of hippocampal CA3 pyramidal neurons has been investigated. The results revealed a significant increase in the number of dendritic spines of apical and basal dendrites in rats subjected to restraint stress (6 h per day for 21 days). The number of excrescences were also markedly increased in stressed rats. The physiological significance and possible mechanism for increased spine density is discussed.
