RESUMO
Objective: To compare the function of expelling water retention with drastic purgative of crude and vinegar stir-baked Kansui Radix in cancerous ascites model rats. Methods: Furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with powder of crude and vinegar stir-baked Kansui Radix and their alcohol and water extract for 7 d. The amounts of urine and ascites, the levels of urinary sodium, potassium, chlorideion, and pH value, and the contents of PRA, Ang II, ALD, and ADH in serum were investigated. Results: Compared with model group, the amount of urine of each medication administration group significantly increased (P < 0.05, 0.01), the amount of ascites, the levels of urinary sodium, potassium, chlorideion, and pH value (P < 0.01), and the contents of PRA, Ang II, ALD, and ADH in serum all showed a significant decrease (P < 0.05, 0.01). Among them, the groups which were administered with powder of crude and vinegar stir-baked Kansui Radix were the most significant, and there was no significant difference between the two groups. Conclusion: The powders of crude and vinegar stir-baked Kansui Radix have a remarkable effect on expelling water retention with drastic purgative, and they could improve the symptom of cancerous ascites model rats.
RESUMO
Objective: To study the effects of different extracts of Kansui Radix stir-baked with vinegar (KRV) on the function of expelling water retention with drastic purgative in cancerous ascites model rats. Methods: The cancerous ascites model rats were respectively ig administered with KRV powder, ethanol extract, aqueous extract, and ehanol and aqueous extract of KRV (340 mg/kg) for 7 d. The amounts of urine and ascites, the levels of urinary sodium, potassium, chloride ion, and pH value, and the contents of PRA, Ang II, and ALD in serum were investigated. UPLC-QTOF MS technology was used to explore the components differences in various extracts of KRV. Results: Compared with the control group, the amount of urine in model group was significantly reduced (P<0.05), the ascites generated, and the urinary sodium, potassium, chloride ion, pH value, and the contents of PRA, Ang II, and ALD in serum were all significantly increased (P<0.01). Compared with the model groups, the treatment groups showed decreasing trend in ascites; The amounts of urine in positive groups, powder groups, ethanol and aqueous extract groups showed a significant increase (P<0.05); The level of urinary sodium of water extraction groups showed significant decrease (P<0.05); The levels of urinary sodium, potassium, chloride ion, pH value, and the contents of PRA, Ang II, and ALD in serum of positive groups, powder groups, ethanol extract groups, and ethanol and aqueous extract groups all showed a significant decrease (P<0.05, 0.01). Diterpenes were inspected in the alcohol extract and alcohol and aqueous extract, fewer in the aqueous extract. Conclusion: Powder groups and ethanol and aqueous extract groups of KRV have remarkable effect on expelling water retention with drastic purgative, and there is no significant difference between the two groups, which could provide the basis for clinical medication of KRV that is made into the pill and powder. Diterpenes in KRV may be the active components on the function of expelling water retention with drastic purgative.
