[Clinical and experimental studies of rheum on preventing progression of chronic renal failure].

Rheum, a well known herb unique in its cathartic effect is now introduced to prevent progression of uremia. A clinical prospective trial was conducted to evaluate its effect in comparison with the Captopril. 30 cases with initial Scr level of 344.8 +/- 114.0 mumol/L were allocated randomly to 3 groups. Rheum E treated group, Captopril treated group and Rheum E + Captopril group. The long term (6-22 mos) follow-up results showed that the progression rate of renal failure, calculated by regression analysis of 1/Scr vs time, was found to be retarded after treatment, being more marked in both Rheum E and Rheum E + Captopril group. Uremic symptoms improved after the treatment with serum albumin level increased. To explore the mechanism of therapeutic effects of Rheum on CRF, a series of experimental studies were performed. Rheum can suppress the proliferation of glomerular mesangial cells in culture. In 5/6 nephrectomized rats, the O2 consumption of remnant kidney was obviously decreased by feeding the animal Rheum E and the hypermetabolic state was ameliorated as well. A group of 5/6 nephrectomized rats were fed with Rheum E for 28 wks. It was found that the level of azotemia of this treated group was lessened remarkably as compared with the controls. The serum albumin and transferrin contents of the treated animals were much higher than the controls while the blood cholesterol and triglycerides decreased unexpectedly. In conclusion, both the in vivo and in vitro studies have proved the effectiveness of Rheum in preventing the progression of CRF.

Clinical effects of rheum and captopril on preventing progression of chronic renal failure.

A clinical trial, to evaluate the effects of a Chinese herbal drug, Rheum E and angiotensin converting enzyme inhibitor, Captopril on chronic renal failure (CRF), was conducted. Thirty cases with initial serum creatinine (Scr) levels of 344.8 +/- 114.0 mumol/L were allocated randomly to 3 groups: Rheum E treated group, Captopril treated group and Rheum E + Captopril group. A control group of 12 cases were on dietary therapy alone. During the 6-22 months of treatment, all the patients were kept on low-protein (0.6g/kg/d), and low-phosphorus (10mg/kg/d) diet. The results showed that the progression rate of renal failure, calculated by regression analysis of 1/Scr vs time, was found to be retarded after treatment with the increased regression coefficient (b value). Scr levels and blood urea nitrogen were kept stable or fell slightly. Albumin rose during the follow-up period (P less than 0.05) in the treated patients, being more marked in both Rheum E and Rheum E + Captopril groups. Uremic symptoms of nausea, anorexia improved in most of the treated patients. It is concluded that long-term low-dose Rheum E taken orally is beneficial to CRF. Its effect is better than that of Captopril. The regime of Rheum E and Captopril is a preferable choice in the long-term treatment for preventing progression of CRF.

[Effect of Rheum tanguticum Maxim ex Balf on cAMP in the central nervous system].

Rabbit model of fever was produced by means of subcutaneous inoculation of pneumocci. Third ventricular intubation and irrigation were carried out in rabbits. Irrigation fluid was collected during the stage of normal temperature, at the peak of fever and when the temperature was lowered by rhubarb. cAMP was detected with RlA in each of the three portions of the irrigated CSF. The result showed that cAMP level was raised during fever and decreased after rhubarb administration. Irrigation of CSF without medication had no significant influence on cAMP level.
