To study the function of expelling water retention with drastic
purgative of different polarities of Kansui Radix stir-baked with
vinegar on the cancerous
ascites model rats, the
furosemide was taken as positive control drug, and the cancerous
ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with
vinegar for 7 d. The amount of urine and
ascites, the level of urinary
sodium,
potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups,
ethyl acetate extract group showed a decreasing trend in
ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary
sodium,
potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of
petroleum ether extract and
n-butanol extract were weaker than that of
ethyl acetate extract. The water exact was the weakest. The results showed that
ethyl acetate extract is the active part of Kansui Radix stir-baked with
vinegar on the function of expelling water retention with drastic
purgative on the cancerous
ascites model rats, alleviating the water-
electrolyte disorder and body fluid
acid-base imbalance, regulating the renin angiotensin aldosterone system.
