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.

[Prevention of local radiation injuries using metronidazole].

The use of small doses of metronidazole (90 mg/kg) for 7 days followed by irradiation of the rat hip at a dose of 66 Gy, increased 1.7 times cicatrization at the site of radiation injuries in comparison with the control group of animals.

[Hemostasis in cancer patients during radiation therapy using metronidazole].

Indices of platelet function, plasmic coagulation and fibrinolysis were studied during gamma-beam therapy in patients with laryngeal, gastric and cervical tumors (potentially at risk for thrombosis) against a background of metronidazole administration. During the above therapy the thrombophilic status of gastric cancer patients was preserved. These patients were considered at risk for thrombosis.

[Hemostatic homeostasis following radio-synovectomy in rheumatoid arthritis].

Platelet functional activity, plasma coagulation and fibrinolysis were studied in patients with rheumatoid arthritis (RA) against a background of various therapeutic modalities. Therapy with non-steroid anti-inflammatory agents resulted in an increase in platelet and plasma coagulating activity and inhibition of fibrinolysis. An insignificant rise of disaggregation of platelet aggregates was noted 2 weeks after intraarticular administration of 198Au against a background of therapy with non-steroid anti-inflammatory agents.

[Use of nicotinic acid and midocalm for correcting blood coagulation in patients with radiation edema of the extremities].

A study was made of the functional activity of platelets, plasmatic coagulation and fibrinolysis in patients with late radiation disorders of the blood and lymph flow during treatment with vasodilative drugs: nicotinic acid and midocalm. These drugs tend to decrease the functional activity of platelets and to raise the blood fibrinolytic activity. Their use is indicated to this group of patients to better their intravascular status.

[Changes in platelet aggregation and fibrinolytic activity of blood in healthy persons during the 23-day physical cycle].

The blood of 100 health humans aged 18 to 40 years was analysed. The aggregation of platelets and blood fibrinolytic activity were shown to change within 23-day physical cycle according to Swoboda and Fliess. In the negative phase the platelets count, their aggregation, desaggregation process and blood fibrinolytic activity were higher than in the positive one.
