And Control

Hyperlipidemia is the immediate results of the excessive fat intake in food. This results in the elevated levels of cholesterol and triglycerides in the blood. This leads to heart conditions like CAD, hypertension, congestive heart failure as risk factors which can be lethal. There are many drugs to treat and control the lipids levels in the body. These drugs are either designed to prevent LDL accumulation and VLDL synthesis. Some drugs also lower the elevated levels of saturated lipids in the body. But many drugs are known to cause side effects and adverse effects; therefore, alternatives to the drugs are the subjects for current investigations. Herbs and medicinal plants are used as treatment sources for many years. They have been used in the Indian medical systems like Ayurveda, Siddha etc. As the application of herbs in the treatment is growing, there is an urgent need for the establishment of Pharmacological reasoning and standardization of the activity of the medicinal plants. Chloris paraguaiensis Steud. is Poyaceae member that is called locally as Uppugaddi. Traditionally it is used to treat Rheumatism, Diabetes, fever and diarrhoea. The chemical constituents are known to have anti-oxidant properties and most of the anti-oxidants have anti-hyperlipidemic activity too. Since the plant has abundant flavonoid and phenol content, the current research focusses on the investigation of the anti-hyperlipidemic activity of the plant Chloris extracts. Extracts of Chloris at 200mg/kg showed a comparably similar anti hyperlipidemia activity to that of the standard drug. The extracts showed a dose based increase in the activity at 100 and 200mg/kg body weight.

Anti Oxidant

Background: Parkinson’s disease ranks second, after Alzheimer’s as the major neurodegenerative disorder, for which no cure or disease-modifying therapies exist. Ample evidence indicate that PD manifests as a result of impaired anti-oxidative machinery leading to neuronal death wherein Cullin-3 has ascended as a potential therapeutic target for diseases involving damaged anti-oxidative machinery. Objective: The design of target specific inhibitors for the Cullin-3 protein might be a promising strategy to increase the Nrf2 levels and to decrease the possibility of “off-target” toxic properties. Methods: In the present study, an integrated computational and wet lab approach was adopted to identify small molecule inhibitors for Cullin-3. The rational drug designing process comprised homology modeling and derivation of the pharmacophore for Cullin-3, virtual screening of Zinc natural compound database, molecular docking and Molecular dynamics based screening of ligand molecules. In vivo validations of an identified lead compound were conducted in the PD model of C. elegans. Results and Discussion: Our strategy yielded a potential inhibitor; (Glide score = -12.31), which was evaluated for its neuroprotective efficacy in the PD model of C. elegans. The inhibitor was able to efficiently defend against neuronal death in PD model of C. elegans and the neuroprotective effects were attributed to its anti-oxidant activities, supported by the increase in superoxide dismutase, catalase and the diminution of acetylcholinesterase and reactive oxygen species levels. In addition, the Cullin-3 inhibitor significantly restored the behavioral deficits in the transgenic C. elegans. Conclusion: Taken together, these findings highlight the potential utility of Cullin-3 inhibition to block the persistent neuronal death in PD. Further studies focusing on Cullin-3 and its mechanism of action would be interesting.

Aim: To evaluate potential of Naphthal-NU, Napro-NU and 5-Nitro-naphthal-NU, 2-chloroethylnitrosourea compounds with substituted naphthalimide in the pre-clinical studies. Materials and Methods: In vitro cytotoxicity of three nitrosoureas was determined in human and mouse tumor cell lines by MTT assays. In vivo anti-tumor potential was evaluated in Sarcoma-180 (S-180) and Ehrlich’s carcinoma (EC) solid tumors. Apoptosis in S-180 cells was analyzed by using Annexin V-Propidium Iodide (PI). Histological analysis of liver and kidney was performed at optimum dose (50 mg/kg). Expression status of CD4+, CD8+ and CD25+ cells in treated mouse were also examined. Results: Significant tumor growth retardation by the compounds was noted in early and advanced disease groups, as the life span of drug treated mice increased considerably. Drug induced killing was observed by induction of apoptosis. Naphthal-NU and 5-Nitro-naphthal-NU were effective to normalize the tumor induced structural abnormalities of liver and kidney. The compounds have no immunotoxic effect on CD4+ and CD8+ T cells and down regulate CD4+CD25+ regulatory T cells. Conclusion: Overall data holds promise for the antitumor activity with lower toxicity of the compounds that can be utilized for the treatment of human malignant tumors.

The in vivo metabolism of insulin is a complex process in which liver, kidney, and muscle are major participants. In this study we evaluated the effect of spontaneous hyperglycemic nonketoacidotic diabetes (DH) and ketoacidotic diabetes (DKA) on insulin clearance and degradation by these organs. Livers, hindlimbs, and kidneys from nondiabetic controls and DH and DKA Bio-Breed rats were isolated and perfused with artificial media. Liver clearance of immunoreactive insulin (ml/min) was significantly higher in DH rats, 6.0 +/- 0.2, but significantly lower in DKA rats, 3.4 +/- 0.5, compared with controls, 4.6 +/- 0.2. Acidosis alone induced by ammonium chloride loading, did not impair liver insulin clearance (4.8 +/- 0.4 ml/min). Muscle responded differently to the diabetic state in that insulin clearance was not altered by DH and DKA. Renal (organ) clearance of insulin was significantly depressed in the DKA state when compared with controls (0.52 +/- 0.04 and 0.75 +/- 0.07 ml X min-1 X g-1, respectively). This could largely be explained by a lower glomerular filtration rate. Fractional urinary insulin clearance was increased twofold above control values in DH kidneys and fourfold in DKA kidneys, indicating that tubular luminal absorption of insulin was impaired in both states. By contrast contraluminal uptake (peritubular clearance) did not differ significantly from controls. 125I-insulin degrading activity of the 100,000 g supernate fraction from muscle homogenates was similar in the diabetic and control groups. However in liver and kidney, degrading activity did not correspond to whole organ insulin clearance in a consistent manner.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment Of Diabetes

Abstract Background The use of Loranthus micranthus in folklore medicine for treatment of diabetes and its associated complications is a common practice around the world. The present study investigated this traditional affirmation by in vivo investigation into the effect of L. micranthus leaf extract on hepatic and renal, oxidative status and glucose metabolism in streptozotocin (STZ)-induced diabetic rats. Methods Diabetes mellitus was induced in adult male Wistar rats by intraperitoneal injection of STZ (60 mg/kg). The diabetic rats were thereafter treated orally once per day with 5 mg/kg gilbenclamide or L. micranthus leaf extract (100 or 200 mg/kg) and monitored for 14 days. Clinical observations, plasma biochemistry, hormonal profile, oxidative stress parameters, glucose metabolism enzymes and histopathologic examination of the liver and kidney were evaluated to monitor treatment-related effects of L. micranthus leaf extract in STZ-induced diabetic rats. Results Loranthus micranthus leaf extract administration significantly ameliorated hyperglycemia-mediated damage by decreasing the blood glucose level (45.9% and 84.7% on days 7 and 14 posttreatment, respectively), enhancing the antioxidant status, inhibiting lipid peroxidation and improving the architecture of the liver and kidney in STZ-induced diabetic rats. Furthermore, intervention of L. micranthus leaf extract restored the liver and kidney function biomarkers and increased the plasma levels of triiodothyronine and thyroxine to normal control in STZ-induced diabetic rats. Conclusions The findings from this investigation provide credible scientific support for the traditional use of L. micranthus leaf extract in the treatment of diabetes and its associated complications.

<p>Free radicals mediated oxidative stress is the major risk factor for many chronic diseases like atherosclerosis, diabetes mellitus, arthritis, cancer, ageing and neurodegenerative diseases. Therapy with anti-oxidants is gradually gaining lot of importance for treatment of such diseases. Hydro-alcoholic extract of <em>Eugenia caryophyllus</em> was studied for its <em>in-vivo</em> antioxidant activity using two different animal models viz. Triton induced hyperlipidemia and High fat diet induced hyperlipidemia. Total phenolic content and total flavonoid content, DPPH assay was also carried out for <em>in vitro</em> anti-oxidant efficacy. Total protein, lipid peroxidation (MDA), reduced glutathione, superoxide dismutase and catalase were evaluated in the liver tissue in Triton induced hyperlipidemia and diet induced hyperlipidemia models. The study findings indicated significant <em>in-vivo</em> and <em>in-vitro</em> antioxidant property that may be related to the amount of polyphenols and flavonoids present in the extract. These results clearly indicate that <em>Eugenia caryophyllus</em> is effective against free radical mediated oxidative stress.</p>

Six marketed oral antidiabetic metformin tablets in Bangladesh have been studied for their drug content, release profile and glucose lowering capacities. This sort of study is a good indicator for in vivo evaluation of the quality of an oral antidiabetic preparation. Marketed preparations of metformin-HCl from different manufacturers were randomly chosen for this study. The drug content was within the United State Pharmacopoeia (USP) specified limit (95-105%) in all cases. The blood glucose levels were investigated in streptozotocin-induced diabetic rats (SIDRs) after 5 hours of single dose (110 mg/kg body weight) treatment of the products; significantly (p<0.05) reduced blood glucose level by 58.1, 53.2, 50.8, 77.0, 72.9 and 49.1%, respectively; which were consistent with antihyperglycemic effects of standard metformin-HCl (71.3%). All the products were found to be qualified in lowering blood glucose level. It may be inferred that the metformin-HCl tablets of Bangladeshi manufacturers complies with the standard specifications for drug contents, dissolution and antihyperglycemic properties.© 2014 JSR Publications.

Nephroprotective Effect

Objective: The present study aimed to evaluate in vivo the antihyperglycemic, anti oxidant,antihyperlipidemic and nephroprotective effects of Stevioside against Alloxan induced diabetic nephropathy in rats. Materials and Methods: In this model diabetes was induced using Alloxan (125 mg/kg, i.p) and the prophylactic treatment was started 48 hours after Alloxan injection for 28 days. The protective effect of the treatment with standard (Glibenclamide 0.5mg/kg, p.o) and Stevioside (250 mg/kg. p.o) were analyzed by estimating the serum levels of glucose, urea, creatinine, albumin, total protein, total cholesterol (TCH), triglycerides (TG), high density lipoproteins (HDL) and antioxidants like SOD, catalase and lipid peroxidation. Key Findings: This study demonstrates that Stevioside improved hyperglycemia and maintained antioxidant status and reduced total cholesterol, TG, urea, creatinine and albumin and lipid peroxidation levels when compared to toxic control. The protective effect of Stevioside against Alloxan induced diabetic nephropathy in rats was also supported by histopathologic findings.The results of the present study are encouraging for its potential use to delay the onset and progression of diabetic renal complications. However, the translation of therapeutic efficacy in humans requires further studies.
