Tau-protein expression in human blood lymphocytes: a promising marker and suitable sample for life-time diagnosis of Alzheimer's disease.

OBJECTIVES: Taking into account the hypothesis that Alzheimer's disease (AD) might be a systemic disease that affects several tissues in the body, the aim of this study was to try to detect the expression of tau-protein in human peripheral blood lymphocytes (PBL) in patients with AD. MATERIAL AND METHODS: Blood samples were obtained from patients with AD (n=16, age 67-98) and from volunteers without psychoneurological pathology (n=10, age 65-78). PBL were isolated on Ficoll-Paque gradient centrifugation.

[Effect of berberine bisulfate on platelet hemostasis in thrombocytopenia patients].

The authors recommend berberine bisulfate for use as thrombocytopoiesis stimulator in thrombocytopenias as they have found secondary therapeutic property of this drug--to increase platelet count in patients with primary and secondary thrombocytopenia. The drug was given as monotherapy and in combined treatment 3 times a day for 15 days in a dose 5 mg 20 min before meals.

[The hemostatic state of patients with breast and lung cancer undergoing hypoxic radiotherapy].

Parameters of functional status of the hemostatic system were studied in 76 breast and lung cancer patients in the course of radiotherapy using TTC-10 hypoxic gas mixture (oxygen--10% and nitrogen--90%) as radioprotector. The thrombophilic status of the blood in breast and lung cancer patients established prior to treatment was accounted for by increased functional activity of platelets, increased capillary blood coagulability, formation of dense clot and inhibition of fibrinolysis. In the course of hypoxyradiotherapy, blood thrombogeneity becomes lower due to a decrease in platelet adhesion.

[Hemostatic homeostasis in rheumatoid arthritis patients after "radiosynoviorthesis" with radioactive gold].

Six to nine months (7.2 months, on the average) after injection of 198Au into large joints of patients with rheumatoid arthritis there was a decrease of blood thrombophilia characteristics of these patients and refractory to correction with conventional remedies. Functional activity of platelets and fibrinolysis studies were the most sensitive laboratory tests enabling one to reveal the lowering of the patients' blood thrombogenic potential after radionuclide therapy.
