InAyurvedic system of medicine in India, not only extracts of one plant or the other but also a combination of plant extracts are used
for the treatment of diabetes mellitus. The present paper reports the combined effect ofAbroma augusta andCoccinia indica known to be useful for the treatment of diabetes in Ayurveda on the fasting blood sugar, glucose tolerance and lipid profile
of Streptozotocin (STZ) induced albino rats. 300mg of water extract of the mixture of dried powdered roots ofA. augusta and leaves ofC. indica in equal proportions was given once daily for 8 weeks. After 8 weeks of treatment of Streptozotocin (STZ) diabetic rats,
the fasting blood sugar came down to almost normal value and improvement in glucose tolerance and serum lipid profile were
also observed. 相似文献

The hypoglycemic effect of the aqueous extract ofAbroma augusta (Family: Steculiceae) was studied in normal as well as alloxan diabetic rats. Treatement of diabetic rats with 4 ml (4gm
dry weight) of agueous extract ofA. augusta for 16 weeks resulted in gradual but significant fall in fasting blood glucose and improvement in glucose tolerance. Serum
total and LDL cholesterol and triacylglycerol which increased in diabetic rats showed improvement. These results show that
the water extract ofA. augusta has both hypoglycemic and hypocholesterolemic effects. 相似文献

Effect of oral administration of 200 mg/Kg body weight of the aqueous extract ofOcimum sanctum (Tulsi) mixed with diet for eight weeks to diabetic (streptozotocin induced) rats was studied. There was significant reduction
in fasting blood glucose, serum lipid profile, lipid peroxidation products, (LPO) and improvement in glucose tolerance. The
aqueous extract also decreased LPO formation (thiobarbituric acid reactive substances TBARS) and increased antioxidant enzymes
superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione transferase (GT) and one antioxidant
reduced glutathione (GSH) in plasma and rat liver, lung, kidney and brain. The decrease in TBARS and increase in GSH, SOD,
CAT, GPX, and GT clearly shows the antioxidant property ofOcimum sanctum. 相似文献

Curcuma longa commonly known as tumeric is traditionally used as a spice in Indian food. A wide range of biological activities e.g. anticancer,
antimicrobial, antiinflammatory and free radical scavenging activity of the plant suggests a logical basis for its traditional
use in foodstuff. Various phytothreapeutic uses ofCurcuma longa have been reviewed. 相似文献

This study was carried out to investigate the effect of oral feeding of water extract of fresh leaves ofAzadirachta indica (Fam:Meliaceae) in streptozotocin induced diabetes and its associated retinopathy in rats. Treatment of the diabetic rats with aqueous extract of leaves ofA. indica at a dose of 250 mg/kg body weight for 16 weeks resulted in gradual but significant fall in blood glucose and improvement in serum total, LDL and HDL cholesterol and triacylglycerol which increased in diabetic rats. It also showed improvement in body weight and reversed retinopathy. 相似文献

In the present study the antioxidative potential ofMomordica charantia, Azadirachta indica, Allium sativum andOcimum sanctum was assessed in streptozotocin induced diabetic rats. Lipid peroxide levels were also measured in normal, diabetic and treated
animals. Malondialdehyde (MDA) levels were significantly higher and antioxidant activity was found low in diabetic groups
as compared to the control groups, and significant alteration in both the MDA levels and antioxidant activity was also observed
when the above herbal hypoglycemic agents were given to diabetic rats. On the basis of our results we conclude thatM. charantia, A. indica, A. sativum andO. sanctum are not only useful in controlling the lipid peroxide levels but are also helpful in further strengthening the antioxidant
potential. 相似文献

The aim of this study was to evaluate the radioprotective effect of turmeric extract (40 mg/kg body weight) and vitamin E
(α- tocopherol acetate, 400 IU/kg body weight) supplementation on lipid peroxidation, reduced glutathione and antioxidant
defense enzymes in various organs like liver, kidney and salivary glands at 24 h in adult Swiss mice. 131Iodine exposure significantly increased lipid peroxidation in kidney and salivary glands in comparison to control animals.
Pre supplementation with turmeric extract for 15 days showed significant lowering of lipid peroxidation in kidney. On the
other hand vitamin E pre supplementation showed marked reduction in lipid peroxidation in salivary glands. Reduced glutathione
levels decreased significantly in liver after radiation exposure. However, pre supplementation with turmeric extract and vitamin
E did not improve glutathione levels in liver. In conclusion, we have observed differential radioprotective effect of turmeric
extract and vitamin E in kidney and salivary glands. However, Vitamin E seems to offer better radioprotection for salivary
glands which is known to be the major site of cellular destruction after radioiodine therapy in patients. 相似文献

Aqueous and alcoholic extracts of amalki (Emblica officinalis), spirulina and wheatgrass were prepared and analyzed for antioxidant
vitamin content (vitamin C and E), total phenolic compounds. Antioxidant status, reducing power and effect on glutathione
S-transferase (GST) activity were evaluated in vitro. Vitamin C content of crude amalaki powder was found to be 5.38 mg/g,
while very less amount 0.22 mg/g was detected in wheat grass. Amalki was rich in vitamin E like activity, total phenolic content,
reducing power and antioxidant activity. Total antioxidant activity of aqueous extract of amalki, spirulina and wheat grass
at 1mg/ml concentration were 7.78, 1.33 and 0.278 mmol/l respectively. At similar concentrations the total antioxidant activity
of alcoholic extract of amalaki, spirulina and wheat grass was 6.67, 1.73 and 0.380 mmol/l respectively. Amalki was also found
to be rich source of phenolic compounds (241mg/g gallic acid equivalent). Alcoholic extract of wheat grass showed 50 % inhibition
in FeCl2- ascorbic acid induced lipid peroxidation of rat liver homogenates in vitro. Both aqueous and alcoholic extracts of amalaki
inhibited activity of rat liver glutathione S-transferase (GST) in vitro in dose dependant manner. Since GST acts as powerful
drug metabolizing enzyme its inhibition by amalaki offers possibility of its use for lowering therapeutic dose of herbal preparations.
The aqueous extracts of both amalki and spirulina also showed protection against t-BOOH induced cytotoxicity and production
of ROS in cultured C6 glial cells. 相似文献

The antimicrobial activity of crude and methanol extract ofTerminalia bellerica dry fruit was tested by disc diffusion method, against 9 human microbial pathogens. Crude aqueous extract of dry fruit at
4 mg concentration showed zone of inhibition ranging from 15.5–28.0 mm.S. aureus was found to be highly susceptible forming highest zone of inhibition, suggesting thatT. bellerica was strongly inhibitory towards this organism. These pathogens were highly sensitive to the methanol extract forming 14.0
to 30.0 mm zone of inhibition suggesting that the methanol extract ofT. bellerica was more effective than crude extract against most of the microbes tested exceptE. coli (enteropathogen) andP. aeruginosa. The minimal inhibitory concentrations (MICs) of crude and methanol extracts were determined by broth dilution technique
which ranged from 300 to >2400 μg/ml and 250 μg to >2000 μg/ml respectively, indicating thatT. bellerica was highly effective againstS. aureus with lower MIC values. There were some biochemical alterations induced byT. bellerica. These results indicate thatT. bellerica dry fruit possesses potential broad spectrum antimicrobial activity. 相似文献

Pretreatment of an ethanolic extract of leaf ofPiper betle linn at a dose of 200mg/kg body weight, orally administered to rats for ten consecutive days, was found to possess a significant
protective action against gastric lesions induced by indomethacin. The extract pretreatment resulted in significant increase
in superoxide dismutase (SOD) and catalase (CAT) activity, increase in mucus, hexosamine and total thiol group content, but
marked reduction in oxidatively damaged protein and peroxidised lipid levels as compared to untreated ulcerated control. The
extract was also found to possess both superoxide and hydroxyl free radical scavenging action. The present observations establish
the efficacy of the extract in prevention of experimentally induced peptic ulcer by indomethacin and antioxidant property
appears to be predominantly responsible for such cytoprotective activity in the experimental model. 相似文献

The effect of the oral administration ofVitex negundo leaf extract on the levels of enzymic and non-enzymic antioxidants were studied in the adjuvant induced arthritic (AIA) rats
The levels of antioxidant enzymes such as SOD, CAT, GPx, G6PD, GSH and Vit-C were estimated in various groups of the experimental
rats. It was observed that the antioxidant enzyme levels in the AIA were significantly low when compared to normal rats. A
significant decrease in enzymic antioxidant—SOD, CAT, GPx, G6PD and non-enzymic antioxidant—GSH, Vit-C were observed in the
liver of AIA rats compared to the normal rats. These results suggest that the leaf extract ofVitex negundo possesses antioxidant activity. 相似文献

Aqueous extract of the leaf and root ofNauclea latifolia Sm. (Rubiaceae) is used in Nigerian folk medicine for the treatment of hypertension. This work is carried out to investigate
the effect ofNauclea latifolia leaf extract on lipid profile and cardiovascular activity of rats. Normal and 10% coconut oil fed rats were treated with
the water-soluble fraction of the ethanol extract ofNauclea latifolia leaf for 2 weeks. Forty-eight mature male albino rats of the Wistar strain were divided into two experiments of four groups,
each group having 6 animals. Experiment I animals were treated with the water-soluble fraction of the ethanol extract whilst
experiment II animals were fed 10% coconut oil meal before treatment with the water-soluble fraction of the ethanol extract.
A single oral dose ofNauclea latifolia was 170, 340 and 510 mg/kg body wt/day of the extracts respectively for 2 wks. There was no significant change in the lipid
profile of the experimental animals as compared with the controls. There was about 40% relaxation on contracted thoracic aorta
that was pre-contracted with 2 μM phenylephrine. The viability of the tissue was tested against 10 μM of acetylcholine. There
was no significant (P>0.05) change in Na+ concentration in the serum. However, the K+ concentration in the serum of the experimental animals showed a significant increase. The study shows that ethanol extract
ofNauclea latifolia has vasodilator action on the aorta and that lipid profiles of experimental rats were not affected. Furthermore, the increase
in the K+ may be contributing to the vasodilator effect ofNauclea latifolia. 相似文献

This study was carried out to see the effect of the aqueous extract ofOcitum sanctum Linn (Tulsi) with Vitamin E on biochemical parameters and retinopathy in the streptozotocin-induced diabetic albino male
rats. Adult albino male rats weighing 150–200 gm were made diabetic by intraperitoneal injection of streptozotocin in the
dose 60 mg/kg in citrate buffer (pH 6.3). The diabetic animals were left for one month to develop retinopathy. Biochemical
parameters like plasma glucose, oral glucose tolerance and glycosylated hemoglobin HbA1c, were measured along with lipid profile, and enzymes like glutathione peroxidase (GPX), lipid peroxidase (LPO), superoxide
dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST) in normal, untreated diabetic rats and diabetic rats treated
withOcimum sanctum L extracts and vitamin E. Fluorescein angiography test was done for assessing retinopathy. Results on biochemical parameters
were analyzed statistically by using ANOVA followed by Dunnet's ‘t’-test. A p-value of <0.05 was considered as significant.
Evaluation of biochemical profile in treated groups showed statistically significant reduction in plasma levels of glucose,
HbA1c, lipid profile and LPO, and elevation of GPX, SOD, CAT and GST. Treatment of the diabetic animals withOcimum sanctum and Vitamin E, alone and in combination for 16 weeks showed reversal of most of the parameters studied including plasma glucose
levels. Angiography showed improvement in retinal changes following combined antidiabetic treatment. 相似文献

The aim of the present study was to evaluate the antihyperglycemic and antilipidperoxidative effects of ethanolic seed extract
ofTephrosia purpurea (TpEt) in streptozotocin induced diabetic rats. Hyperglycemia associated with an altered hexokinase and glucose 6 phosphatase
activities, elevated lipid peroxidation, disturbed enzymatic and non-enzymatic antioxidants status were observed in streptozotocin
induced diabetic rats. Oral administration of “TpEt” at a dose of 300mg/kg bw showed significant antihyperglcemic and antilipidperoxidative
effects as well as increased the activities of enzymatic antioxidants and levels of non enzymatic antioxidants. We also noticed
that the antihyperglycemic effect of plant drug (TpEt) was comparable to that of the reference drug glibenclamide. Our results
clearly indicate that “TpEt” has potent antihyperglycemic and antilipidperoxidative effects in streptozotocin induced diabetic
rats and therefore further studies are warranted to isolate and characterize the bioactive antidiabetic principles from “TpEt”. 相似文献

Aqueous extract of the wood ofPterocarpus marsupium, commonly known as ‘bijasar’, is used in Indian Ayurveda system of medicine for treatment of diabetes. The active anti-diabetic
principle in its aqueous extract has been found to be (-)epicatechin, a flavonoid. The present work was undertaken to study
the effect of (-)epicatechin on erythrocyte membrane Ca++-ATPase from type 2 diabetic patients. The activity of erythrocyte Ca++-ATPase was significantly lower in type 2 diabetics.In vitro insulin treatment of erythrocyte ghosts, resulted in the increase of Ca++-ATPase activity in diabetic patients. Treatment with (-)epicatechin (1mM) resulted in an increase in the activity of erythrocyte
Ca++-ATPase in both normal individuals and type 2 diabetic patients. The insulin like effect of (-)epicatechin on erythrocyte
membrane Ca++-ATPase in type 2 diabetics is an interesting finding. Further work is needed to elucidate the mechanism of action of (-)epicatechin
on modulation of erythrocyte membrane bound enzymes. 相似文献

Water extract of dry fruits ofTerminalia chebula (Hindi-Harda, Telugu-Karakkaya) at a dose of 200 mg/kg body weight improved the glucose tolerance as indicated by 44% of
reduction in the peak blood glucose at 2nd hour in glucose tolerance test in diabetic (streptozotocin induced) rats. Treatment of diabetic rats with an initial fasting
blood glucose of 253±9.4 mg/dl daily once with the water extract (200 mg/kg) for two weeks brought down the fasting blood
glucose to 123±8.4 mg/dl which is only slightly above the normal value. These results indicate that water extract of Terminalia
chebula improves glucose tolerance and brings down fasting blood glucose in diabetic rats. 相似文献

Diabetes mellitus is one of the most common endocrine metabolic disorders. Dual endocrine deficits of impaired insulin action (insulin resistance) and inadequate insulin secretion create an environment of chronic hyperglycemia and general metabolic disarray. Oxidative stress plays an important role in diabetic pathogenesis. Oxidative stress induced by streptozotocin (STZ) has been shown to damage pancreatic beta cell and produce hyperglycemia in rats. The present study was made to evaluate the antioxidant activity of ethanolic extract of the Evolvulus alsinoides in STZ induced rats. The antioxidant activities were done by using standard protocols. For histopathological analysis, the pancreatic tissues of all experimental groups were fixed with 10 % formalin for 24 h then the samples were stained with hematoxylin–eosin for the microscopic observation. Our results showed the significant decrease in lipid peroxidation and increases in the antioxidant (both enzymatic and nonenzymatic) levels after treatment with standard as well as the E. alsinoides. There is no significant difference between control and plant alone group rats. The histopathology reports also revealed non-toxic effect and protective effect of E. alsinoides in the kidney of STZ induced diabetic rats. Our result indicated that the E. alsinoides extract effectively increased the antioxidant level thereby it prevents oxidative stress during diabetes mellitus and also it showed the protective effect on kidney of STZ induced rats. Hence it can be used to maintain the antioxidant level during diabetes mellitus. 相似文献

Oral administration of ethanol extract of the rhizome ofPirorhiza kurroa at a dose of 20mg/kg body weight, for 10 consecutive days, was found to enhance the rate of healing on Indomethacin-induced
gastric ulcer in rats, compared to the ulcerated group without treatment. The level of peroxidised lipid, in terms of thiobarbituric
acid reactive species (TBARS), in gastric tissue, was increased in ulcerated rats which was restored to near normalcy on treatment
with ethanol extract. The specific activity ofin vivo antioxidant enzymes, viz SOD and catalase and total tissue sulfhydryl (thiol) group, which were markedly decreased in ulcerated
group, were found to be significantly elevated (p<0.05), on treatment with the above extract, at the specified dose, compared
to the indomethacin—induced ulcerated group without any supporting treatment. The present study thus suggests that the ethanol
extract of rhizome ofPicrorhiza kurroa, at the dose of 20mg/kg body weight, accelerated the healing of stomach wall of indomethacin induced gastric ulcerated rats
by anin vivo free radical scavenging action. 相似文献

In this study antioxidant activity of methanol extract of rhizomes ofCurculigo orchioides (MEC) was investigated using carbon tetrachloride (CCl4)-intoxicated rat liver as the experimental model. The hepatotoxic rats were administered MEC for 90 days (daily, orally at
the dose of 70 mg per kg body weight). Lipid peroxidation (LPO) in CCl4-intoxicated rats was evidenced by a marked increment in the levels of thiobarbituric acid reactive substances (TBARS) and
diene conjugates (CD), and also a distinct diminution in glutathione (GSH) content in the liver. In CCl4+MEC—treated rats these biochemical parameters attained an almost normal level. The decreased activity of antioxidant enzymes,
such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and glutathione reductase (GRD) in CCl4—intoxicated rats, and its retrieval towards near normalcy in CCl4+MEC—administered rats revealed the efficacy of MEC in combating oxidative stress due to hepatic damage. Elevated level of
glutathione transferase(GTS) observed in hepatotoxic rats too showed signs of retuming towards normalcy in MEC co-administered
animals, thus corroborating the antioxidant efficacy of MEC. The findings provide a rationale for further studies on isolation
of active principles and its pharmacological evaluation. 相似文献
