[Ulcerostatic effect of tris-[2-hydroxyethyl] ammonium salt of iron-containing polyacryl acid and its possible mechanisms]. / Ul'tserostaticheskii éffekt tris-[2-oksiétil] ammoniinoi soli zhelezosoderzhashchei poliakrilovoi kisloty i ego vozmozhnye mekhanizmy.

The study investigated a stimulating effect of tris-[2-hydroxyethyl] ammonium salt of iron-containing polyacryl acid on proliferative processes in the connective tissue in development of experimental gastric ulcer. The drug was found to exhibit an ulcerostatic effect, to change the levels of collagen, noncollagen proteins, glycosaminoglycan fractions, DNA and RNA.

[A biochemical analysis of the possible mechanisms of the ulcerostatic action of atranes]. / Biokhimicheskii analiz vozmozhnykh mekhanizmov ul'tserostaticheskogo deistviia atranov.

Stimulatory effect of metalloatrans on the development of stomach wall connective tissue components was examined in rats with experimental acetate ulcer. Metalloatrans were shown to inhibit peroxide oxidation processes of lipids in blood and stomach tissue.

[Possible mechanisms of anti-ulcer action of silatranes]. / K voprosu o vozmozhnykh mekhanizmakh ul'tserostaticheskogo deistviia silatranov.

A stimulating effect of methylethyl(silatrane-I-ilmethyl)-sulphonium iodides, 1-(ethoxy)silatranes and 1-(chloromethyl)silatrane on the processes of rat test acetate ulcer healing is studied. Silatranes efficiency is not inferior to oxyferriscorbone and exceeds that of methacil. It is shown that all preparations inhibit the processes of lipids peroxidation in the blood, in liposomes and stomach tissue.

Improvement of disability and akinesia of patients with Parkinson's disease by intravenous iron substitution.

Akinetic crises are one of the problems arising in patients with Parkinson's disease in particular after long term treatment with levo-dihydroxyphenylalanine (L-DOPA). They are characterized by severe disability to move. Increasing dosages of L-DOPA and decarboxylase or monoaminooxidase inhibitors do not improve these symptoms. Intravenously applied iron in the form of a ferri-ferro-complex exhibits a considerable benefit for all patients treated so far. They regained a remarkable mobility. Their disability score dropped from up to 90 percent down to 30 percent. The effect is dosage-dependent, and withdrawal of iron will lead again to akinetic crises.

[Mechanism of formation of blocking factors and method of antiblocking immunotherapy in malignant tumors]. / O mekhanizme obrazovaniia blokiruiushchikh faktorov i metode antiblokiruiushchei immunoterapil zlokachestvennykh opukholei.

A hypothesis on blocking factor formation in carcinogenesis is discussed. Destabilisation of cell membranes and increased levels of proteolytic enzymes in tumor tissue are considered to be the trigger mechanism. Protease level in large bowel tumor was found to be higher than in normal tissue. Plasminogen level in cancer patients was significantly higher than in healthy subjects. Application of different experimental schemes of treatment with membrane-stabilizing drugs and an inhibitor of protease was followed by antitumor and antiblocking effects. Sorption of rheumatoid factor and immune complexes from plasma led to a decrease in the blocking activity of plasma in vitro. In cases of rectal cancer, plasmapheresis was followed by tumor regression and a fall in immune complex concentration.

[Effect of 1-(chloromethyl)silatrane on biochemical indices in the tissue of experimental gastric ulcer]. / Vliianie 1-(khlormetil)silatrana na biokhimicheskie pokazateli tkani éksperimental'noi iazvy zheludka.

It has been demonstrated in rats with experimental gastric ulcer that 1-(chloromethyl) silatrane intensifies the development of granulation-fibrous tissue and favours optimization of the ratio of collagens and glycosaminoglycans, the main connective tissue biopolymers. Furthermore, 1-(chloromethyl) silatrane produces a more pronounced effect on hexosamine-containing glycoproteins in the ulcer tissue as compared with methyluracil and oxyferriscorbon. At the same time, judging by the time course of sialoproteins, the antiulcerous drugs, methyluracil and oxyferriscorbon, are much more effective antiinflammatory agents than 1-(chloromethyl)silatrane.

Randomized double-masked trial of sodium oxyferriscorbone for the treatment of gastric ulcers.

A double-blind 4-week trial of sodium oxyferriscorbone versus placebo (distilled water) was conducted in 46 outpatients with endoscopically confirmed gastric ulcer. Ulcer healing occurred in 15 of 20 patients receiving sodium oxyferriscorbone (75%) and in 7 of 20 patients receiving placebo (35%). Patients receiving sodium oxyferriscorbone experienced less pain and required less antacid than those receiving placebo (P less than 0.05). Side effects were reported in 12 patients, 7 while receiving sodium oxyferriscorbone and 5 while receiving placebo. Six patients did not complete the study due to ulcer complications. Routine laboratory tests revealed no persistent abnormalities that could be related to the treatment. Five placebo-treated patients that were therapeutic failures were switched to sodium oxyferriscorbone and healing was observed within 3 weeks. It is concluded that sodium oxyferriscorbone is effective in enhancing healing of gastric ulcers.
