Analysis on Mechanism of Adenine-induced Kidney-Yang Deficiency Rats Treated with Different Processed Products of Curculiginis Rhizoma / 中国实验方剂学杂志

Objective:To study on the mechanism of invigorating kidney and strengthening Yang of different processed products of Curculiginis Rhizoma aqueous extracts in rats with kidney-Yang deficiency induced by adenine. Method:Taking Guifu Dihuang pills as the positive drug group (the dosage of 2.466 g·kg-1), after intragastric administration for 4 weeks, enzyme-linked immunosorbent assay (ELISA) was used to compare the effects of different processed products of Curculiginis Rhizoma aqueous extracts (the dosage of 2.742 g·kg-1) on the levels of thyroid stimulating hormone (TSH), 17-hydroxycorticosteroids (17-OHCS), estradiol (E2), testosterone (T), triiodothyronine (T3), thyroxine (T4) and cortisol (COR) in serum of rats with kidney-Yang deficiency induced by adenine. The activity of cytochrome P450 3A (CYP3A) in rat liver and kidney microsomes was determined by Nash colorimetry. Result:All the processed products aqueous extracts could improve the function of hypothalamus-pituitary-target gland axis in rats with kidney-Yang deficiency induced by adenine, and the total score was in the order of Euodiae Fructus juice-processed products (29 points)>salt-processed products (25 points)>rice wine-processed products (23 points)>raw products (17 points)>Zingiberis Rhizoma juice-processed products (11 points). And the different processed products of Curculiginis Rhizoma could increase CYP3A activity of liver and kidney microsomes of kidney-Yang deficiency rats, especially the Euodiae Fructus juice-processed products and salt-processed products. Conclusion:All the processed products of Curculiginis Rhizoma can effectively treat the syndrome of kidney-Yang deficiency in rats, among them, Euodiae Fructus juice-processed products and salt-processed products have more significant effect on invigorating kidney and strengthening Yang.

Study on decoction's effect of different processed rhizomes of Cibotium barometz on retinoic acid induced male rats osteoporosis / 中国中药杂志

This study compared the decoction's HPLC figures of the different processed rhizomes of Cibotium barometz including the raw, the sand-baked, the wined, the steamed and the salted, on the basis of which, with the sand-baked Drynaria fortunei decoction as the positive control group, comparingall groups' decoction, concentration of which was 104.2 g x L(-1), for 4 weeks, by their effects (s-TRAP and total scores of OPG, Ca, P, IL-6, TNF-alpha and IL-1) on retinoic acid induced male rats osteoporosis. The experiment results showed the sand-baked and the wined were better than the steamed, the salted and the raw;in the processing methods' selection, the sand-baked was a better heating method than the steamed and the rice wine was the better excipient than the salt. It provided a reference to explain the processing principle of rhizomes of C. barometz and work mechanism of anti-osteoporosis.

Detection on effect of different processed Cibotium barometz on osteoblasts by CCK-8 / 中国中药杂志

The pancreatic enzyme-II type collagenase digestion method was adopted for primary culture of osteoblasts, inoculation and passage. They were identified by alkaline phosphatase dye-liquor. N-butanol extract fractions from different processed products of Cibotium barometz were prepared. The above osteoblasts were jointly cultured with protocatechuic acid, protocatechuic aldehyde, kojic acid and the mixed control liquid of the above three substances, and their proliferation was detected by CCK-8. Various n-butanol extract fractions from different processed products of C. barometz showed a significant proliferative effect on osteoblasts in the order of the wined > the heated > the salted > the sand-heated and wined system > the alcohol-processed > the steamed > the crude. The q test showed no significant difference among sand-heated, alcohol-processed and steamed C. barometz, no significant difference between heated and salted C. barometz. Various control substances also showed a certain proliferative effect on osteoblasts in the order of the mixed control > protocatechuic aldehyde > protocatechuic acid > kojic acid. The q test showed no significant difference between protocatechuic aldehyde and protocatechuic acid. All of n-butanol extract fractions from different processed products of C. barometz showed a significant effect on osteoblast proliferation, of which wined C. barometz showed the best effect. All of phenolic compounds such as protocatechuic aldehyde, protocatechuic acid and kojic acid showed a significant proliferative effect on osteoblasts.
