[The antitumor properties of honey].

The experimental evaluation of antitumor properties of honey was carried out using five strains of rat and murine tumors. Honey revealed moderate antitumor and pronounced antimetastatic effects. Honey potentiated the antitumor activity of 5-fluorouracil and cyclophosphamide.

[Potentiation of the selective antitumoral effect of cyclophosphamide and 5-fluorouracil by its combination with amphotericin B and diacarb].

The paper deals with the results of experiments which were carried out on 10 tumor models and used approximately 1,000 animals (mice and rats of different strains). Such cytostatic drugs as cyclophosphamide (alkylating agent) and 5-fluorouracil (antimetabolite) showed a significantly enhanced antitumor and metastation--preventing effect when used in combination with polyene antibiotic amphotericin B and a diuretic drug--diacarb. This was matched by a pronounced amelioration of toxic side effects and an increase in the animals' lifespan. The said method of treatment should be integrated with oncological practice.

[Antimetastatic properties of aloe juice].

An evaluation of antimetastatic properties of succus Aloës was carried out using three types of experimental tumors of mice and rats. It was found that succus Aloës treatment contributes to reduction of tumor mass, metastatic foci and metastasis frequency at different stages of tumor progress without affecting major tumor growth. Succus Aloës potentiates the antitumor effect of 5-fluorouracil and cyclophosphamide as components of combination chemotherapy.

[Effect of amphotericin B on the diuretic action of diacarb and various indicators of water-salt metabolism in healthy and tumor-bearing animals].

The experiments with albino rats, Wistar rats and SHK mice showed that the combined use of amphotericin B and diacarb markedly potentiated the effect of the latter: the amount of the urine excreted within 6 h and the renal excretion of sodium ions increased 1.8 and 1.5 times, respectively. Analogous trends were observed in the experiments with stabilization of the animal water balance by 2 per cent water loading. The studies on rats with Pliss lymphosarcoma showed that the diuresis level in the tumor-bearing animals was 3 times lower than that in healthy rats. The treatment with 5-fluorouracil lowered this index more significantly. With the use of amphotericin B, diacarb and their combination the urination level came to normal. The cyclophosphamide therapy of mice with sarcoma 180 was accompanied by accumulation of water in the tumor tissue. The combined use of the cytostatic with the polyenic antibiotic and diuretic resulted in a significant lowering of this index. In rats with Walker-256 carcinosarcoma, the treatment with the above three drugs lowered the sodium ion concentration and increased the calcium ion concentration in the tumor tissue. At the same time the electrolyte level in some organs not affected with malignant tumor (spleen, thymus, liver and adrenal glands) returned to normal.

[Hematopoietic indices in rats with sarcoma 45 in the process of treatment with cytostatics and diuretic agents].

Sarcoma 45 growth in rats was noted to be followed by the development of anemia and leucocytosis. Sessional use of 6-mercaptopurine and cyclophosphane resulted in the enhancement of anemia, the development of leucopenia, and suppression of bone marrow hemopoiesis. The suppression of hemopoiesis was much less manifested, if cytostatics were used together with diuretics (diacarbe or furocemid).

[Toxicity of benzhydrylurea under experimental conditions].

Benzhydrylurea, which displays an anticonvulsant action and is of low acute toxicity in capable after a 3-month administration to rats to inhibit the growth of male-rats, intensify the excretion of protein with the urine, raise the blood sugar level (with its single administration--to reduce), provoke dystrophic changes in the liver, kidneys and central nervous system. Following a 1--3-week introduction of the substance guinea pigs and cats demonstrate hemorrhagic erosions in the stomach and small intestine (but not rabbits, dogs and rats), the appearance of pathological forms of erythrocytes, while guinea pigs suffer from leucopoietic disorders.
