The fruit of Phoenix pusilla Garetn. has been used in herbal medicines, as it is sweet, sour, cooling and laxative, cardiotonic, aphrodisiac, carminative and roborant. The objective of the present study was to investigate the antioxidant and antidiabetic effect of ethanolic extract of unripe fruit of Phoenix pusilla in streptozotocin-induced diabetic rats. The extract was analyzed for the presence of various phytoconstituents like tannins, flavonoids, vitamin C, vitamin E, protein, carbohydrates, lipids and phenolic compounds. Streptozotocin (40 mg/kg body weight, i.p.) was administered to induce diabetes in adult rats. The extract (100 and 200 mg/kg) and glibenclamide (6 mg/kg) were administered orally for 21 days to evaluate antioxidant and antidiabetic activity. Blood glucose, serum total cholesterol and triglycerides levels were estimated. Carbohydrate and lipid metabolizing enzymes glucose-6-phosphatase, fructose-1,6-diphosphatase, glycolytic enzymes like hexokinase and liver-function enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx), production of thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALP), renal-function markers like urea and creatinine level were also measured. Histopathology of pancreas was studied. The results indicated that extract normalized the blood, liver, renal and pancreatic functions in streptozotocin-induced diabetic rats. Hence it can be concluded that the extract possesses antioxidant and antidiabetic activity. The findings support the conventional usage of Phoenix pusilla unripe fruit in treating diabetes.

Diabetes Melitus

Introduction: Diabetes mellitus or diabetes is a metabolic ailment which occurs as a result of insulin insufficiency or defect in insulin function, or both that leads to ihyperglycemia. Diabetes mellitus is a worldwide disease even though its prevalence in other countries vary. Kalanchoe crenata belongs to the family crassulaceae. It is also known locally as miracle plant and often utilized in Africa for medicinal purposes. The study was designed to ascertain the antidiabetic and dyslipidemic activity and effects of the ethanolic extract of both leaves and stem of Kalanchoe crenata on istreptozotocin incite diabetic rats for three (3) weeks. Methodology: 6-8 weeks old Sprague dawley rats received multiple injection of streptozotocin intraperitoneally (40mg/kg body weight) to induce diabetes melitus. Diabetes mellitus was observed and confirmed after six days of induction. The rats were given ethanolic extract of Kalanchoe crenata remarkably (10, 30 and 100mg/kg) and 5mg/kg glibenclamide orally twice daily for three weeks. Blood glucose, lipids, creatinine, urea, were then determined. Results: After week three of treatment 5mg/kg glibenclamide, 30 and 100mg/kg ethanolic extract of Kalanchoe crenata remarkably (p<0.05) decrease glycemia and improved lipidemia by decreasing overall cholesterol, LDL-C and increasing HDL-C likened to the control diabetic group. Also results from treated rats remarkably decrease blood urea nitrogen and creatinine. However, the affirmative control and the sampled treated groups showed curative and regenerative effect in the cells responsible for producing endocrine insulin “beta cells of the islets of Langerhans” located in the pancreas. Kidney and liver tissue sections of treatment groups showed a reversal of diseased insults made by the streptozotocin. Conclusion: The outcome of the research indicate that given ethanolic extract of Kalanchoe crenata remarkably contains the necessary phytochemicals for the development of a standard and effective herbal medicine for Diabetes mellitus and related complications and also with no toxic effects on the tissues of the liver, pancreas and kidney.

Zusanli Acupoint

The purpose of this study was to investigate the effects of electroacupuncture at Zusanli acupoint on the enteric neuropathy in diabetic rats. Sprague–Dawley rats were divided into different groups depending on the total electroacupuncture span and frequency. The expression of nitric oxide synthase (nNOS), choline acetyltransferase (CHAT), protein gene product 9.5 (PGP9.5), and doublecortin was significantly decreased in the diabetic group compared with the control group. Long-term electroacupuncture at Zusanli with either high frequency or low frequency could increase the expression levels of nNOS, CHAT, PGP9.5, and doublecortin, and the increase was greater in the high-frequency group. But no obvious changes were seen in the short-term electroacupuncture groups. These results suggest that electroacupuncture at Zusanli can restore the deficiency of enteric neurons in diabetes partly but a comparative long duration of stimuli (6 weeks) is required. The increase of doublecortin may be involved in this positive process.

Background: Caffeine consumption by children and adolescents has risen dramatically in recent years, yet the lasting effects of caffeine consumption during adolescence remain poorly understood. Aim: These experiments explore the effects of adolescent caffeine consumption on cocaine self-administration and seeking using a rodent model. Methods: Sprague-Dawley rats consumed caffeine for 28 days during the adolescent period. Following the caffeine consumption period, the caffeine solution was replaced with water for the remainder of the experiment. Age-matched control rats received water for the duration of the study. Behavioral testing in a cocaine self-administration procedure occurred during adulthood (postnatal days 62–82) to evaluate how adolescent caffeine exposure influenced the reinforcing properties of cocaine. Cocaine seeking was also tested during extinction training and reinstatement tests following cocaine self-administration. Results: Adolescent caffeine consumption increased the acquisition of cocaine self-administration and increased performance on different schedules of reinforcement. Consumption of caffeine in adult rats did not produce similar enhancements in cocaine self-administration. Adolescent caffeine consumption also produced an upward shift in the U-shaped dose response curve on cocaine self-administration maintained on a within-session dose-response procedure. Adolescent caffeine consumption had no effect on cocaine seeking during extinction training or reinstatement of cocaine seeking by cues or cocaine. Conclusions: These findings suggest that caffeine consumption during adolescence may enhance the reinforcing properties of cocaine, leading to enhanced acquisition that may contribute to increased addiction vulnerability.

We tested the hypothesis that dietary fi bre (DF) has protective effects against manganese (Mn)-induced neurotoxicity. Forty-eight one-month old Sprague-Dawley rats were randomly divided into six groups: control, 16 % DF, Mn (50 mg kg-1 body weight), Mn+ 4 % DF, Mn+ 8 % DF, and Mn+ 16 % DF. After oral administration of Mn (as MnCl2) by intragastric tube during one month, we determined Mn concentrations in the blood, liver, cerebral cortex, and stool and tested neurobehavioral functions. Administration of Mn was associated with increased Mn concentration in the blood, liver, and cerebral cortex and increased Mn excretion in the stool. Aberrations in neurobehavioral performance included increases in escape latency and number of errors and decrease in step-down latency. Irrespective of the applied dose, the addition of DF in forage decreased tissue Mn concentrations and increased Mn excretion rate in the stool by 20 % to 35 %. All neurobehavioral aberrations were also improved. Our fi ndings show that oral exposure to Mn may cause neurobehavioral abnormalities in adult rats that could be effi ciently alleviated by concomitant supplementation of DF in animal feed.

Previous studies found that Kelulut Honey produced by Trigona spp. bees is able to prevent oxidative damage in various pathological conditions.  Thus, the present study aimed to determine whether Kelulut Honey could prevent the sperm and testicular damage in streptozotocin-induced diabetic rats. Male Adult male Sprague-Dawley rats were divided into four groups: Non-Diabetic (NDM), Non-Diabetic with Kelulut Honey supplementation (NDMKH), Diabetic without supplementation (DM) and Diabetic with Kelulut Honey supplementation (DMKH).  Kelulut honey was given at the dose of 2.0 g/kg weight daily via gavage for 28 consecutive days. Results showed that sperm quality produced by diabetic rats supplemented with Kelulut honey significantly improved compared to the diabetic control groups (p<0.05). SOD activity and GSH level increased significantly (p<0.05) whereas PC and MDA levels significantly decreased in sperm and testis of DMKH rats when compared to DM rats (p<0.05). Histological observation showed obvious increase in spermatozoa in the lumen of epididymis and increased spermatogenic cells density in the testis of DMKH group.  In conclusion, Kelulut Honey has a potential in preventing the damage of sperm and testis in diabetic rats.

Diabetes mellitus has been treated orally with herbal remedies based on folk medicine since ancient times.Embelia ribes burm(Myrsinaceae), known commonly as vidanga, was used in Ayurveda for its anthelmintic activity. Ayurveda describes vidanga as pungent, causes increase in digestive fire, and cures flatulence and colic. A single study reported the antihyperglycemic activity of decoction ofE. ribesin glucose-induced hyperglycemic albino rabbits. In the present study, the lipid-lowering and antioxidant potential of ethanolic extract ofE. ribes burmwas investigated in streptozotocin (40 mg/kg, IV, single injection)-induced diabetes in rats. Twenty days of orally feeding the extract (200 mg/kg) to diabetic rats resulted in significant (P< 0.01) decrease in blood glucose, serum total cholesterol, and triglycerides, and increase in HDLcholesterol levels when compared to pathogenic diabetic rats. Further, the extract also lowered the liver and pancreas thiobarbituric acid–reactive substances (TBARSs) values (P< 0.01) when compared to TBARS values of liver and pancreas of pathogenic diabetic rats. The results of test drug were comparable to gliclazide (25 mg/kg, orally), a standard antihyperglycemic agent. This is the first pilot study to provide biochemical evidence of potential ofE. ribesin diabetic dyslipidemia.

Aged rats are more sensitive to injury, possibly through an impairment of nitrogen and glutamine (Gln) metabolisms mediated by glucocorticoids. We studied the metabolic kinetic response of adult and old rats during glucocorticoid treatment. The male Sprague-Dawley rats were 24 or 3 mo old. Both adult and old rats were divided into 7 groups. Groups labeled G3, G5, and G7 received, by intraperitoneal injection, 1.50 mg/kg of dexamethasone (Dex) for 3, 5, and 7 days, respectively. Groups labeled G3PF, G5PF, and G7PF were pair fed to the G3, G5, or G7 groups and were injected with an isovolumic solution of NaCl. One control group comprised healthy rats fed ad libitum. The response to aggression induced specifically by Dex (i.e., allowing for variations in pair-fed controls) appeared later in the aged rats (decrease in nitrogen balance from day 1 in adults but only from day 4 in old rats). The adult rats rapidly adapted to Dex treatment, whereas the catabolic state worsened until the end of treatment in the old rats. Gln homeostasis was not maintained in the aged rats; despite an early increase in muscular Gln synthetase activity, the Gln pool was depleted. These results suggest a kinetic impairment of both nitrogen and muscle Gln metabolisms in response to Dex with aging.

Abstract BackgroundSulfotransferases (SULTs) are phase II drug-metabolizing enzymes. SULTs also regulate the biological activities of biological signaling molecules, such as various hormones, bile acids, and monoamine neurotransmitters; therefore, they play critical roles in the endocrine and nervous systems. People are subject to various kinds of physical, chemical, toxicological, physiological, and psychological stresses at one time or another. The study of the effects produced by stress may lead to finding novel remedies for many disease conditions. The effect of repeated restraint stress on rat SULT expression has not been studied. MethodsThis study involves the effect of repeated restraint stress on SULT1A1 expressions. Male Sprague-Dawley rats (n=4) were subjected to repeated restraint stress 2 h/day for 7 days. Protein and RNA expression of SULT1A1 were analyzed by western blot and quantitative real time reverse transcription polymerase chain reaction, respectively, in important tissues. ResultsWe observed that repeated restraint stress increased the expression of SULT1A1 in the liver, adrenal glands, cerebellum, hypothalamus, and cerebral cortex in male rats. Patterns of enhanced expression were observed at both mRNA and protein level, indicating that repeated restraint stress stimulates enzyme expression at the transcriptional level. ConclusionsChanges of SULT1A1 expression in important tissues caused by repeated restraint stress will have a significant effect on drug metabolism and xenobiotics detoxification. The significant changes in endocrine glands and brain sections may also cause disturbances in hormone homeostasis, therefore leading to disease conditions. This report provides clues for the understanding of the effect of stresses on health.
