ABSTRACT
BACKGROUND:
Diabetic glycometabolism disorder and lipoid metabolism disorder are often reciprocal causation, which cause the reduction of hepatic glycogen and the changes of many plasma factors. Hence, the occurrence of vascular complications in heart, kidney and brain is common. It becomes a hot topic in latest researches to find an effective medicine for the secondary prevention of diabetes.OBJECTIVE:
To study the interventional effects of leizhusun' s juice on hepatic glycogen, plasma glucose and blood fat.DESIGN:
A randomized and controlled observatory study by employing experimental animals as subjects.SETTING:
Laboratory of Pharmacy College of Xianning College.MATERIALS Totally 40 male Wistar rats with a bodymass of (230 ± 20) g were obtained from the Experimental Animal Center of Wuhan General Hospital of Guangzhou Military Area.METHODS:
The diabetic rat model was established by the injection of Alloxan(200 mg/kg) into abdominal cavity in the laboratory of Pharmacy College of Xianning University between September 2002 and June 2003. Leizhusun' s juice(LZS) of different doses(205.70 mg/kg and 436. 40 mg/kg) was respectively perfused into the stomach for 28 days, and healthy rats were used as normal control. Levels of hepatic glycogen(HG) in liver and the factors in plasma were detected.MAIN OUTCOMEMEASURES:
HG, glucose(Glu), triacylglycerol (TG), non-esterified fatty acid(NEFA), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-c), high-density lipoprotein cholesterol (HDL-c), and malondialdehyde(MDA) contents, and superoxide dismutase (SOD) activitiesRESULTS:
The level of Glu in LZS-Ⅱ group(436.40 mg/kg) was (9.65± 1.14) mmol/L, TG was(1. 31 ±0. 18) mmol/L, NEFA was(0. 51 ±0. 04)mmol/L, LDL-c was(0.79 ±0. 19) mmol/L, and MDA was(6.31 ±0. 83)nmol/L, which were significantly lower than Glu of (16. 14 ± 1.59) mmol/L,TG of(1.94 ±0. 31) mmol/L, NEFA of(0.59 ±0. 05) mmol/L, LDL-c of (1.34 ±0.28) mmol/L and MDA of(10.95 ±2.90) nmol/L in experimental control(Model) group( t= 3. 478 - 9. 379, P < 0.01), while the HDL-c was (1.09±0.13) mmol/L, SOD was(39.76±6.23) NU/mL and HG was (6.70 ±0.62) mg/g in LZS-Ⅱ group, which were significantly higher than HDL-c of(0.55 ± 0. 11) mmol/L, SOD of (23.24 ± 3.35) NU/mL and HG of (4.06±1.24) mg/gin Model group( t = 5. 388 - 9. 000, P <0.01). Furthermore, the decreasing effect on LDL-c and increasing effect on SOD in both LZS groups had dose-dependence relationship( P < 0.05 -0.01 ).CONCLUSION:
LZS significantly decreases plasma Glu, TG, NEFA, LDL-c and MDA levels, but increases HDL-c, SOD and HG levels, which displays obvious antidibetic effects.
