Abstract
The invention relates to a natural pharmaceutical composition, a preparation method thereof and application thereof in preparation of toxicity reducing and efficacy enhancing drugs for cancer chemotherapy. The natural pharmaceutical composition consists of a decoction concentrated extract of rhizoma alismatis and andrographis paniculata (Burm.f.) Nees, alisol B acetate and andrographolide which are in the ratio of (3-6):(1-6):(3-8). The composition has an excellent treatment effect on cancer-chemotherapy-related diarrhea and can simultaneously play a synergic role in cancer chemotherapy.
Description
Technical field
The present invention relates to a kind of natural drug composition, relate more specifically to a kind of natural drug composition of being made up of Rhizoma Alismatis Herba Andrographis water boiling concentration extract, Rhizoma Alismatis terpene alcohol B acetas and andrographolide, the preparation method of this natural drug composition and this natural drug composition are being suffered from diarrhoea for the preparation of minimizing cancer chemotherapy dependency and treatment of cancer are being played purposes in the medicine of potentiation.
Background technology
Malignant tumor is current harm humans existence, one of healthy principal disease, and its treatment means comprises operation, chemotherapy, radiotherapy, Chinese medicine, and the effect of chemotherapeutic treatment tumor is particularly outstanding.Chemotherapeutic no matter singly with or unite with toxicity such as all can cause that the patient suffers from diarrhoea, diarrhoea makes the chemotherapy dependency suffer from diarrhoea again behind the chemotherapy of tumors.Emerging and applying along with chemotherapeutics such as 5-fluorouracil, taxanes, hydroxy camptothecin, irinotecan, xeloda etc. in recent years, the incidence rate of chemotherapy dependency diarrhoea improves year by year, and if do not carry out active treatment, easily cause patient's dehydration, malnutrition, serum electrolyte disorder, acid base imbalance etc., it is unfavorable greatly not only the rehabilitation of body to be brought, also bring certain difficulty to CC, therefore effective treatment of chemotherapy dependency diarrhoea has been become the important component part of tumor patient wholistic therapy.
Chemotherapy dependency diarrhoea is with regard to its clinical manifestation, surely belongs to the Chinese medicine category of " having loose bowels ", and Chinese medicine attracts people's attention for the research of having loose bowels, but at present still unmatchful anticancer disease chemotherapy have the Chinese patent medicine of alleviating diarrhoea and potentiation.Therefore, research and develop a kind of high-efficiency low-toxicity, cheap, the natural Chinese medicine that can be used for alleviating cancer chemotherapy dependency diarrhoea and playing the chemotherapeutic sensitivity effect that is easy to promote becomes clinical problem demanding prompt solution.
Rhizoma Alismatis beginning is stated from Shennong's Herbal, classify as top grade, call its " sweet in the mouth, temperature, tonify deficiency win, except cold and heat pathogen, invigorating the spleen and replenishing QI power, longue meat, obey normal hearing and eyesight for a long time, cure mainly diarrhea due to hypofunction of the spleen.Herba Andrographis is herb or the leaf of acanthaceous plant Herba Andrographis (Andrographis paniculata (Burm.f.) Nees), and the nature and flavor bitter cold cures mainly damp-heat dysentery.In recent years, Rhizoma Alismatis and Herba Andrographis antitumaous effect are confirmed, especially Rhizoma Alismatis terpene alcohol B acetas and andrographolide, the inventor is through research and the experiment of each a large amount of formula proportion, obtained optimal drug ratio compositions of the present invention at last, be the compositions of novelty, and proved that it has fabulous curative effect and can play potentiation to cancer chemotherapy simultaneously cancer chemotherapy dependency diarrhoea, has finished the present invention thus.

2, test method:
To mice S
180The inhibition test of sarcoma growth
Employing was gone down to posterity 5-7 days, and well-grown milky ascites is diluted to tumor cell suspension with an amount of physiological saline solution, and cell number is 10
7/ mL, 5 every group, the right axillary fossa subcutaneous vaccination of every Mus 0.2mL (contains oncocyte 2 * 10
6Individual).Inoculation random packet next day, experimental group natural drug composition of the present invention is divided into (200,100mg/mL) two dosage groups, every Mus is irritated stomach 0.5ml, gives cyclophosphamide 10gkg simultaneously
-1D
-1Negative control group gives 0.5mL distilled water; The positive drug group gives cyclophosphamide 10gkg
-1D
-1, successive administration 10 days.The conventional raising, drinking-water, food is not limit.Drug withdrawal next day, mice all takes off cervical vertebra puts to death, and strips subcutaneous solid tumor tumor piece, weighs, and calculates tumor control rate (%) by following formula:
Tumor control rate=(the average tumor of the matched group average tumor of heavy (C)-experimental group heavy (T))/average tumor of matched group heavy (C)
3, result of the test
Natural drug composition of the present invention is low, high dose group all can strengthen the cyclophosphamide agent with to S
180The effect of inhibition degree, especially the strongest with the high dose group effect.(as table 2)
