[Cerebrolysin in the preventive therapy of dementia in elderly patients with mild cognitive impairment: a three-year prospective comparative study].

Objective: To study the efficacy and safety of long-term (3 years) course Cerebrolysin therapy in an open comparative study as a means potentially capable of slowing or preventing the transition of MCI into dementia, as well as to analyze the possibility of Cerebrolysin preventive effect predicting based on clinical and biological parameters.

Material And Methods: In total, 100 patients with aMCI were included in the study, randomly assigned to 2 groups: patients of group 1 (=50) received annual course therapy with Cerebrolysin for 3 years (20 intravenous infusions of Cerebrolysin 20 ml in 100 ml of saline solution for 4 weeks). Group 2 patients underwent annual clinical examination, but did not receive therapy.

Evaluation of Peripheral Neuropathy in Rat Models of Metabolic Syndrome and Diabetes Mellitus.

The dynamics of nephropathy development in rats with type 2 diabetes mellitus, caused by a high-fat diet and the streptozotocin administration (25 mg/kg), and metabolic syndrome, caused by addition of 20% fructose solution to the diet, was evaluated during the experiment. Models with moderate severity of metabolic changes without significant changes in body weight were obtained after 24 weeks. To study neuropathy severity, the method of electroneuromyography was used; the velocities of motor and sensory excitation propagation along the caudal nerve fibers were measured.

Dihydroquercetin-Loaded Liposomes Change Fibrous Tissue Distribution in the Bleomycin-Induced Fibrosis Model.

The effects of the antioxidant dihydroquercetin (DHQ) were studied in a model of pulmonary fibrosis. DHQ penetration into the lesion was facilitated by encapsulation into liposomes. Pulmonary fibrosis was modeled in rats by intratracheal injection of bleomycin.

Comparison of Metabolic Changes after 6 Months of High-Carbohydrate Diet or High-Fat Diet with Low Dose Streptozotocin Injection in Rats.

We compared 2 models of metabolic syndrome in rats: high-fat diet (58% calories) with single streptozotocin injection at a dose of 25 mg/kg and replacement of water with 20% fructose solution. The model with fructose solution did not cause the main signs of metabolic syndrome over 24 weeks: concentrations of glucose, triglycerides, cholesterol, weight, and BP did not significantly differ from the control group (standard diet). At the same time, single streptozotocin administration was followed by the development of persistent hyperglycemia, hypertriglyceridemia, hypercholesterolemia, and signs of visceral obesity.

[Efficacy and safety of choline alfoscerate in the preventive therapy of dementia in elderly patients with Mild Cognitive Impairment: a three-year prospective comparative study].

Objective: To study the efficacy and safety of the use of annual course therapy of choline alfoscerate (CA) as a drug potentially capable of slowing or preventing the transition of amnesic type mild cognitive impairment (aMCI) into clinically pronounced dementia in a three-year open comparative study, as well as to explore the possibility of predicting the preventive effect of such therapy based on a number of clinical and biological parameters.

Material And Methods: The study included 100 patients with aMCI, randomly divided into 2 groups: the therapeutic group consisted of 50 patients who received CA course therapy once a year for 3 years (20 intravenous infusions of 1000 mg (4 ml) in 100 ml of saline solution for 4 weeks) and a comparison group of 50 patients who underwent an annual examination at the center and did not receive therapy. Clinical and psychopathological, psychometric, immunological, follow-up, and statistical methods were used.
