- Pre-cancerous diseases are morphologically detectable precursors of malignant tumors.
- Chemical agents so-called cytostatics, which inhibit cell growth and, as a result of the rapid, disorderly growth of malignant tumors, attack them more strongly than healthy tissue.
- cytostatics often do not lead to a permanent cure of the cancer, but rather to a temporary containment and delay of tumor growth, so that the successful use of cytostatics in the fight against cancer is only possible to a limited extent.
- these cytostatics due to their growth inhibition, these cytostatics also damage the healthy cells of the organism and especially the immune system, so that their use has serious side effects. is bound.
- the use of cytostatics has only shown promise for certain types of tumor.

- the extraction of the mold extract is not restricted to specific production processes. However, it is advisable to choose a method in which a sufficient effectiveness of the mold extract is guaranteed without the extract must then be concentrated. The necessary cleaning measures should also be kept to a minimum. Furthermore, the mold extract, which also has proteolytic properties, should not decompose itself during storage, which may require a sufficiently long maturation of the mold extract. In the manufacturing process described below, all steps must be carried out under sterile conditions in order to prevent foreign bacteria from colonizing. The use of a sterile workplace according to the current state of the art is therefore absolutely necessary.

- An aqueous medium is preferably used.
- an alcoholic or aqueous-alcoholic medium can be used.
- Isotonic saline is particularly suitable.
- Mold cells have very resistant cell walls. Breaking open the cell walls is therefore difficult.

- the suspension of the mold cells in the cell disruption bomb is preferably repeatedly pressurized with nitrogen up to a suitable pressure of approx. 100 bar, equilibrated in each case for approx. 30 minutes and relaxed to normal pressure, this cycle preferably being carried out at least ten times. It makes sense to work with ice cooling when breaking open the cell walls.
- the modalities of maturing the cell suspension vary from case to case and must be tailored to the individual case. It has, however, been shown that the suspension can expediently be matured by subjecting the suspension to an ultrasound treatment every day for one hour under sterile conditions for at least 8 months.
- an adequate purity of the extract is required.
- the extract is expediently first filtered through glass wool and / or Celite, then cell-free filtered through a filter with a maximum pore size of 0.4 ⁇ m and / or preferably sterile filtered through a filter with a maximum pore size of 0.2 ⁇ m.

Hyphae were removed from a turf of the blue mold Penicillium roqueforti grown on Sabouraud glucose agar according to Example 2 using a sterile lancet, with which the tissue fluid was contaminated. The sample was then incubated at 37 ° C. for one hour and then homogenized by trituration with a pestle in a small agate mortar. Approximately 20 ⁇ l of this suspension were placed in the right circular depression of the agar gel according to FIG. 3.

- Example 6 Modified Bussard Migration Electrophoresis
- serum samples of a tumor patient which had been mixed with the additives specified below one hour before pipetting in, were subjected to a modified Bussard migration electrophoresis, in which the antibodies were in principle dependent on the electroendosmotic properties of the gel in Move towards the cathode and the antigens towards the anode and form visible precipitation lines when they meet.
- Polyclonal antihuman serum was pipetted into the starting holes marked Kl, 2, 3, 4 in the gel plate according to FIG. 7.
- the serum samples were pipetted into the opposite starting holes, namely a serum sample (K1) diluted accordingly with isotonic saline solution, two serum samples (2 and 4) spiked with a Penicillium candidum extract according to Example 1, the extract beforehand with isotonic saline solution in a ratio of 1 : 3 had been diluted (ie the protein breakdown of the diluted extract was 5% per hour), and a serum sample mixed with the undiluted Penicillium candidum extract according to Example 1 (3).
- Fig. 7 shows a photograph of the gel after completion of the migration electrophoresis. As can be seen, in the samples (2, 3 and 4) treated with the Penicillium candidum extracts, the precipitation lines are partially erased compared to the untreated sample (C1). This effect is particularly pronounced in the undiluted candidum extract according to Example 1.
- Example 7 Standardization of a Penicillium candidum extract. Example 1 was repeated. It was determined in clinical self-experiments that this concentration was still too high for injective applications of the extract; strong necrosis formed at the injection site, which was probably due to the high protease content. After a dilution of the above extract in a ratio of 1: 3 with isotonic saline (corresponding to a protein reduction of approx. 5% in the diluted extract), there was practically no necrosis after a subcutaneous injection of 1 ml. Only slight reddening of the skin was observed, so that this concentration was considered to be practicable. In this diluted Penicillium candidum extract, the L-gamma-glutamyl

- 70 mg of a Penicillium roqueforti extract, which had been prepared according to Example 2 were added to a culture. Only 2 ml of isotonic saline was added to the other culture. Both cultures were then incubated at 37 ° C for 6 hours.
- EXAMPLE 9 Detection of the Mitosis-Inhibiting Effect of the Penicillium Candidum Extract in a Blood Culture
- the extract of the mold Penicillium candidum according to Example 1 was tested for the mitosis-inhibiting effect.
- the result was essentially identical to that of the Penicillium roqueforti mushroom extract.
- One of the inventors contracted Bowen's disease (precancerous disease) on the right tibia. After confirming the diagnosis by biopsy (cf. FIG. 10), the inventor treats himself by injecting 2 ml of the diluted Penicillium candidum extract according to Example 7 about 1 cm next to the diseased area of the skin. After two weeks of treatment, the swelling of the skin had decreased and only one scar was visible. A repetition of the biopsy showed a completely unsuspicious cell image (see Fig. 11).
- Example 11 Chromosome representation (standardized method) Two vials of chromosome medium 1A (company Gibco, California, USA (now Invitrogen Co ⁇ oration): unpublished mixture of Eagle's Minimum Essential Medium, fetal calf serum, heparin, antibiotics and phytohaemagglutinin) were each with 5 ml of attached solvent dissolved. 0.2 ml was placed in one of the vials the diluted Penicillium candidum extract according to Example 7, into which the other is sterile pipetted the same amount of isotonic saline. After both vials were warmed to 37 ° C, 0.2 ml of venous blood was added to each. Then both samples were incubated at 37 ° C for 70 hours.
