Valorphin

In all series, the cells are incubated for 48 hours beginning with the hour 0. All substances are dissolved in FBS-supplied RPMI-1640 medium. Negative control cells are incubated in the absence of test substances. The reference samples are incubated with epirubicin or Valorphin in the concentrations equivalent to those applied in the experimental seria and for the corresponding time intervals. The effect is evaluated by staining with MTT dye^[2].

Mice^[2]
In the basic experiment, 49 mice are randomized in 4 groups: two groups (12 animals each) corresponding to the negative control, the reference group (13 animals) and the experimental group (12 animals). The control and the reference group are treated as in preliminary experiment, the experimental group are injected with the mixture of Valorphin (1 mg/kg) and epirubicin (25 mg/m²), dissolved in 0.9% NaCl solution in distilled water. Three injections (volume 0.2 mL) are made with 6-day intervals. Since no reliable difference in tumor size or lifespan of animals in the two negative control groups are observed, the data obtained in these groups are pooled. At day 20 after the first injection, the size of the tumors are determined. Tumor volumes are calculated, inhibition of tumor growth is determined. Percentages of survival are determined for 1-26 days of treatment. The observation is quitted after the total death of the animals in the negative control group^[2].
