Diclofenac and metformin synergistic dose dependent inhibition of hamster fibrosarcoma, rescued with mebendazole.

We examined whether combinig diclofenac and metformin in doses equivalent to human doses would synergize their anticancer activity on fibrosarcoma inoculated to hamsters and in vitro. Rescue experiment was performed to examine whether the prosurvival NF-κB stimulation by mebendazole can reverse anticancer effects of the treatment. BHK-21/C13 cell culture was subcutaneously inoculated to Syrian golden hamsters randomly divided into groups (6 animals per group): 1) untreated control; treated daily with 2) diclofenac; 3) metformin; 4) combinations of diclofenac and metformin at various doses; 5) combination of diclofenac, metformin and mebendazole; 6) mebendazole.

Disulfiram and metformin combination anticancer effect reversible partly by antioxidant nitroglycerin and completely by NF-κB activator mebendazole in hamster fibrosarcoma.

We investigated the anticancer effect of disulfiram and metformin combination on fibrosarcoma in hamsters. Hamsters of both sexes (~ 70 g) were randomly allocated to control and experimental groups (8 animals per group). In all 10 groups, 2 × 10 BHK-21/C13 cells in 1 ml were injected subcutaneously into the animals' backs.

Co-treatment with nitroglycerin and metformin exhibits physicochemically and pathohistologically detectable anticancer effects on fibrosarcoma in hamsters.

We investigated the effect of nitroglycerin with metformin on fibrosarcoma in hamsters. Syrian golden hamsters of both sexes, weighing approximately 60 g, were randomly allocated to control and experimental groups, with 8 animals per group. In all groups, 2 × 10 BHK-21/C13 cells in 1 ml were injected subcutaneously into the animals' backs.

Physicochemical and pathohistological changes in experimental fibrosarcoma tumors of hamsters treated with metformin and itraconazole.

The anticancer effects of metformin (an antihyperglycaemic agent) and itraconazole (an antifungal agent), which are established non-oncologic drugs, were investigated in the present study. The weight, diameter, volume, density, surface, surface to volume ratio and immunohistochemistry of experimental fibrosarcoma tumors were investigated in hamsters treated with metformin and itraconazole. Briefly, the hamsters were injected with BHK-21/C13 cells in order to induce fibrosarcoma, and the animals were treated daily with metformin, itraconazole or a combination of the two drugs.

Caffeine induces metformin anticancer effect on fibrosarcoma in hamsters.

Objective: We investigated the effect of metformin and caffeine on fibrosarcoma in hamsters.

Materials And Methods: 32 Syrian golden hamsters of both sexes, weighing approximately 100 g, were randomly allocated to 3 experimental and 2 control groups, with a minimum of 6 animals per group. 2 x 106 BHK-21/C13 cells in 1 ml were injected subcutaneously into the animals' back in 4 groups.

Effect of metformin on fibrosarcoma in hamsters.

Objective: We investigated the effect of metformin on an in vivo solid tumor model of fibrosarcoma in hamsters.

Materials And Methods: 33 Syrian golden hamsters of both sexes, weighing approximately 100 g, were randomly allocated to 3 experimental and 2 control groups. 2 x 106 BHK-21/C13 cells in 1 ml were injected subcutaneously into the animals' back in 4 groups.

Prostaglandin E2, trace elements and levels of oxidative processes in spontaneous miscarriages.

Objective: We investigated the significance of prostaglandin (PG)E2, trace elements level, pro-oxidative and antioxidative parameters changes in spontaneous miscarriages.

Patients And Methods: In the 125 first trimester pregnancies, 35 with complete spontaneous abortion (group S), 40 with missed abortion (M) and 50 healthy (H), PGE2 plasma concentrations were analysed by commercial ELISA kits, plasma trace elements colorimetrically, lipid peroxidation and the antioxidative enzyme activities in hemolysate by commercial sets. Student's t-test and ANOVA were applied.

Individualization of a pharmacokinetic model by fractional and nonlinear fit improvement.

This study presents application of a new linear and nonlinear fractional derivative two compartmental model to the evaluation of individual pharmacokinetics. In the model, the integer order derivatives are replaced by derivatives of real order. A specific nonlinear function is used for the fit improvement of a fractional derivative two compartmental model with the mass balance conservation.
