  1. Prof. T. Hajtó: - Medical University Pécs /Hungary ContainingPAMP likeArabinoxylanmolecules is BioBranthebeststandardizedimmunomodulatorwhichcan be used in thetumourtherapy?

  2. HEALING POWER OF THE NATURE Yasuo Ninomiya, the founder of Daiwa Pharmaceutical which produces Biobran said: ‟We believe that it is of the utmost importance to trust in nature, with which we must co-exist. We believe that the body’s natural healing power provides the foundation necessary to correct physical imbalances.”

More than 20 yearsagoitwasshownthatstandardizedbranriceextractsactivate NK cells Natural killer cells (Large Granular Lymphocytes) for monitoring of the natural immune defence .Dr.Hiroaki Maeda, Head of Research and Development at Daiwa Dr.Ghoneuman immunologist at the University of California in Los Angeles, USA.

  4. More than 20 years ago: ADORATION of T LYMPHOCYTES T cells recognizes 10 15 EPITOPES on surface of TU cells.NK cells recognize only stress related molecules on TU cells with limited specificity. It is not the firstserious error of TUresearch.Now 20 yearslater this laughis stopped.WHY ? Szöveg

  6. Twenty years ago Enthusiasm: T cells recognize 1015-1016 epitopes TODAY It is well documented that cancer cells are very often characterized by loss or down regulation of MHC-class-I molecules which are not reversible and not reparable. It leads to a definitive escape of tumour cells from T cell lyse.

  8. INNATE IMMUNE SYSTEM Consequently, again and again growing attention is focusing on theeffector cells of innate immune system which are able to kill tumor cells in non-MHCrestricted manner. This system exhibits a polarity and a TU- induced disturbed balance. NK cells is only a soldier in the type-1 system. Namely, the innate immune system is committed in two directions and their balance is disturbed:Tumour-induced suppression of Type-1 cells Tumour-induced dominance of Type-2 cells Pioneers of tumour immunology Type-1 Type-2

  9. Tumour-inducedsuppression of Type-1 cellsType-1macrophages (M1) and from the monocytes originating type-1 maturedentriticcells (D1) generate proinflammatory cytokines, IL-12 and activate cytotoxic effector (such as NK and NKT) cells which are potent inhibitors of tumor growth. However, these type-1 cellsaredefective in tumour patients. Type-1 (cellular) Type-2 (humoral)ModeratelymodificatedIllustrationfromJS. Murray[ImmunolToday1998; 19: 157-63].

  10. TUMOUR-INDUCED DOMINANCE OF TYPE-2 NATURAL IMMUNE CELLSAvailable information suggests that tumour-associatedmacrophages belong to the prototypic Type-2 (M2) population. M2 macrophages and thefrom plasmocytoidprecursors originating D2 dentritic cells generate IL-4 and IL-10 which facilitate the generation of Th2 cells and inhibit Th1 cells aswellasthe type-1 natural system. M2 macrophages and D2 dentritic cells affect inflammation, promote cell proliferation by producing growth factors, stimulate angiogenesis and tissue repair. Tumour patients can have up to 40% M2 peripheral monocytes incontrasttohealthy individuals who have only 10%.Type-1 (cellular) Type-2 (humoral) .

  21. .What is theoptimalapplicationscheme of BIOBRAN? BIOBRAN (ARABINOXYLAN) ALONE was given in very various application schemes: the doses varied betwen 5g daily and 1 g daily wihout break or with break of two or three or five days a week.

  24. The results of Ali is in agreementwiththeobsevations ofChiba University 20 years ago wherethe scientists soconcluded that the effect of Biobran is less if the number of NK cells and their activity is high. S. Bright: Biobran 2017; DHD (EUROPE) LIMITED, organizational 811 03 Bratislava

  27. Previous cross over investigations with lectin indicated that twice a week may be more effective. Because of synergy we applied twice a week.

  29. In spite of factthatArabinoxylan (in BioBran) exhibits a clinicalevidence, the „door of castle” is notopened. No furtherclinicaltrialswerecarried out. The reason is simple: in spite of manyresearch a wellstandardized and evidencebasedphytotherapy is ignoredbythe „GENERAL’ of castle” sinceit is phytotherapy. .

  33. Clinicalresults . 2.) Can the plant PAMP molecules show clinical benefit if they are combined with conventional chemotherapy?

  34. LIVER-METASTASESAfter a chemotherapy hepatic tumors rarely dissappear completely and the duration of responses is short. Hepatic resection in many cases results in also no long-term benefit. Therefore it was interesting that standardized plant immunomodulators were found to help for induction and for prolongation of complete remissions. Primarytumor OthertherapyImm.Th.

  37. A 70-year old patient had an inoperable stomach cancer (T3N1Mx). She was treated with pre-adjuvant chemotherapy. After three cycles Epirubicin +Cisplatin+Xeloda without immune therapy in CT investgation no change of her tumour size was found. The following three cycles of chemotherapy (given in the same doses) was combined with standardized plant immunomodulators and this resulted in nearly complete remission. Her body weight increased with 11 kg. She was operable. The little rest of tumor was surgical removed and in the next four years she was tumour-free.

  47. MEK + BRAF Inhibitors • MEK (MitogenactivatedExtracellularsignal regulationKinase) – inhibitorscan down regulate a receptor tyrosinkinasemediatedsignaling pathway (byinhibition of mitogenactivated protein kinase /MAPK/ cascade). Itcanresult in a decrease of cellproliferation. BRAF inhibitors show a synergisticeffectwith MEK inhibitors. • MEK and BRAF inhibitorshavebeenidentifiedastherapeutictargets in cancer. The clinicalresultsareoftenonlytransient and completeremission is rarelyobserved. (Smith MP, Wellbrock C. ClinCancer Res • 2016 Oct 19.)
