Introduction: Azadirachta indica (neem) is one of the plants commonly used in African traditional medicine for the treatment and management of diabetes mellitus. The present study was undertaken to evaluate the effect of aqueous extract of A. indica leaves on hematology, lipid profile and organ-system function of streptozotocin-induced diabetic male rats. Methods: Thirty albino rats of Wistar strain, weighing between 120 and 150 g, were randomly divided into 6 groups (A-F) and used for the study. Group A was used as a healthy normal control. Groups B-F were induced with diabetes using 50 mg/kg bodyweight (bw.) of streptozotocin. Group B was diabetic untreated; Group C was treated with 100 mg/kg bw. metformin; Groups D to F were treated with 100, 200 and 400 mg/kg bw. of the aqueous extract, respectively. The treatment was carried out daily for a period of 28 days. At the end of the experimental period, the hematological parameters were analyzed using auto haematology analyser. Lipid profiles and histopathological investigations were performed using standard methods. Results: The results obtained showed that aqueous extract of A. indica significantly (p < 0.05) increased the hemoglobin concentration, packed cell volume, red blood cell count, and platelet count of the streptozotocin-induced diabetic rats compared with those of the diabetic-untreated rats. The mean hemoglobin concentrations for groups A, B, C, D, E and F were 11.78, 8.200, 15.18, 13.88, 14.03 and 14.93, respectively. Treatment with the graded doses of the aqueous extract of A. indica significantly (p < 0.05) reduced the total cholesterol, low-density lipoprotein cholesterol, triglycerides and very-low-density lipoprotein, compared with those of the diabetic-untreated control. Treatment also significantly (p < 0.05) increased the high-density lipoprotein cholesterol (HDL-c), compared with that of the control. The mean HDL-c concentration for groups A, B, C, D, E and F were 49.58, 29.79, 40.89, 38.53, 40.40 and 46.54, respectively. The histopathological studies showed regeneration of the pancreas, liver, kidney, heart, brain and lungs for the groups treated with the extract, compared with the diabetic-untreated animals that revealed severe damage to the organ-system functions. Conclusion: These results suggest that the aqueous extract of A. indica can be considered as an excellent remedy for diabetes and a substitute for drugs to reduce complications associated with diabetic conditions.

<p>The study was designed to evaluate the hepatoprotective activity of aqueous extract of cardamom in acute experimental liver injury induced by gentamicin. Twenty four male albino rats were randomly divided into four groups (six rats in each). Animals of the first group served as control and orally (p.o.) received (1 ml/kg saline). The second experimental group was given gentamicin (80 mg/kg i.p.) for 7 days. Third and fourth groups were given aqueous extract of cardamom (100 and 200 mg/kg p.o.) + gentamicin for 7 days, respectively. The degree of hepatoprotection was measured using serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, albumin, and lipid profile levels. In the acute liver damage induced by gentamicin, cardamom aqueous extracts (100 and 200 mg/kg, p.o.) significantly reduced the elevated serum levels of AST, ALT, bilirubin, cholesterol, triglycerides and low density lipoprotein cholesterol (LDL-chol) in gentamicin induced hepatotoxicity. Also cardamom aqueous extracts (100 &amp; 200 mg/kg, p.o.) significantly increased the lowered serum levels of albumin and high density lipoprotein cholesterol (HDL-chol) in gentamicin induced hepatotoxicity rats. Histopathological examination of the liver tissues supported the hepatoprotection. Our findings concluded that cardamom aqueous extracts possessed hepatoprotective activity against gentamicin induced hepatotoxicity in rats.</p>

Rutin, a food derived-polyphenolic bioflavonoid, has been acknowledged for several health benefits. This study aims to explore the ameliorative effects of rutin against carbon tetrachloride (CCl4) toxicity in male rats. Adult male rats were given either CCl4 (30% in olive oil, 3 ml/kg b.w. intraperitoneally) alone or in combination with rutin (70 mg/kg intragastrically) twice a week for 4 weeks. Our data showed that rutin mitigated CCl4 hepatorenal damage, as indicated by diagnostic markers (i.e., transaminases, alkaline phosphatase, total bilirubin, total protein, albumin, urea, uric acid and creatinine), and histopathological findings. In addition, CCl4 induced profound elevation of free radical generation and oxidative stress, as evidenced by increasing lipid peroxidation and reducing catalase, superoxide dismutase and glutathione peroxidase activities in liver, kidney and testicular tissues; these effects were suppressed by coexposure with rutin. Moreover, the increase in the levels of serum triglycerides, cholesterol, low-density lipoprotein cholesterol, and very-low-density lipoprotein cholesterol induced by CCl4 was effectively counteracted by rutin. The decrease in the level of high-density lipoprotein cholesterol in the CCl4 group was also counteracted by rutin treatment. Interestingly, the decreased levels of hormonal mediators associated with sperm production, including serum testosterone, luteinizing hormone and follicle-stimulating hormone, and the impaired sperm quality induced by CCl4 were reversed by rutin. Data from the current study clearly demonstrated that rutin supplementation could at least partly overcome CCl4-induced hepatotoxicity, nephrotoxicity and reproductive toxicity by antioxidant and antidyslipidemic effects.

A modification of Friedewald’s formula to estimate serum low-density lipoprotein cholesterol (LDLC) up to serum triglyceride (TG) level of 11.3 mmol/L in Bangladeshi population has recently been published. The aim of this study was to compare the modified formula with direct measurement of LDLC in Bangladeshi population in a different setting. One thousand and fifty two specimens from adult subjects were analyzed. Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDLC), LDLC and TG were measured by standard methods. The modified Friedewald’s formula was applied to estimate LDL cholesterol concentration. Results were expressed as mean ± SD and calculated LDLC was compared with measured LDLC by two-tailed paired t test, Bland-Altman plot for absolute bias, Pearson’s correlation coefficients of calculated LDLC with measured LDLC and Passing & Bablok regression equation of calculated LDLC against measured LDLC. The mean ± SD of measured LDLC was 2.98±0.82 mmol/L. LDLC calculated by modified Friedewald’s formula was 2.77±0.86 mmol/L. The mean absolute bias was –0.20±0.32 mmol/L, Pearson’s correlation coefficient (r) was 0.9293 (P<0.0001) and Passing & Bablok regression equation was y= – 0.3856+1.0597x for modified formula up to serum TG?11.3 mmol/L. Compared to original Friedewald’s formula, performance of the modified Friedewald’s formula was better up to serum TG?4.52 mmol/L. The study reveals that the modified Friedewald’s formula may be used to calculate LDLC approximately in Bangladeshi population.

In this study, attempt is made to establish changes in serum and liver lipoprotein cholesterols accompanying Plasmodium berghei malarial infection in mice treated with aqueous extract of Ganoderma lucidum at 100, 250, and 500 mg/kg body weight in comparison with 15 mg/kg chloroquine (CQ). Significant increases in all the lipoprotein fractions were observed in infected untreated mice compared with normal control mice. Treatment with 100 and 250 mg/kg G. lucidum extract produced significant reduction in serum total cholesterol (TC) and low-density cholesterol (LDL-C) contents compared with 500 mg/kg G. lucidum and CQ. Treatment with CQ, however, produced significant reduction in hepatic TC and LDL-C compared with the extract. A dose-dependent significant increase in serum high-density lipoprotein cholesterol (HDL-C) was observed in the G. lucidum treated mice compared with normal control but significantly lower compared with CQ-treated mice. Liver HDL-C level was significantly higher in CQ-treated mice compared with normal control and significantly lower compared with G. lucidum-treated and infected untreated mice. A dose-dependent effect of the extract was observed in both serum and liver very-low density lipoprotein cholesterol (VLDL-C). The implication of these results is discussed with respect to the parasite survival and proliferation in the serum and liver.

Hypercholesterolemia is commonly associated with obesity that leads to heart diseases and diabetes. The hepatocardioprotective activity of parsley and carob methanol extract was tested in hypercholesterolemic male rats. Twenty-four male albino rats were divided into four groups (n=6). Group 1 was the negative control group fed with fat rich diet, group 2 (G2) was hypercholesterolemic rats fed with fat rich diet with 2% cholesterol, and group 3 and group 4 (G3 and G4) were hypercholesterolemic rats supplemented with 2% cholesterol and cotreated with 20% w/w parsley seed methanol extract and 20% w/w carob legume methanol extract, respectively. The experiment was conducted for eight weeks. The positive hypercholesterolemic rats showed significant increase in serum levels of total cholesterol, triglycerides, low density lipoprotein (LDL), very low density lipoprotein (VLDL), lactate dehydrogenase (LDH), creatine kinase-mb, liver function enzymes, and decrease in the high density lipoproteins (HDL). Moreover, heart and liver tissues were ameliorated and nearly restored their normal appearance. It could be concluded that both parsley and carob extracts supplementations have a protective effect against hyperlipidemia and improved the histological alteration in heart and liver tissues. The methanol extract of parsley appeared to be more efficient than that of carob in lowering hypercholesterolemia.

Acrylamide (AA) is a well-known potent carcinogen and neurotoxin that has been recently linked to atherosclerotic pathogenesis. The present study is aimed at investigating the protective effect of silymarin (SIL) as an antioxidant against AA-induced hyperlipidemic cardiomyopathy in male rats. The obtained results showed that animals exposed to AA exhibited a significant increase in the levels of cardiac serum markers, serum total cholesterol, triglycerides, low-density lipoprotein cholesterol, and very-low-density lipoprotein cholesterol with a significant decrease in high-density lipoprotein cholesterol. Furthermore, AA intoxication significantly increased the malondialdehyde level (a hallmark of lipid peroxidation) and reduced antioxidant enzyme activities (i.e., superoxide dismutase, catalase, and glutathione peroxidase). SIL administration significantly attenuated all these biochemical perturbations in AA-treated rats, except for the decreased high-density lipoprotein cholesterol. Our results were confirmed by histopathological assessment of the myocardium. In conclusion, this study demonstrated a beneficial effect of SIL therapy in the prevention of AA-induced cardiotoxicity by reversing the redox stress and dyslipidemia in experimental animals.

Aim: This study was carried out to investigate anti-lipidaemic effects of aqueous and ethanolic seed extracts of Datura stramonium. Methods: A total of twenty five albino rats weighing between 150 – 180 g were used. They were divided into five groups each contained five rats. Group 1, was the normal control and thus received normal saline. Groups 2 and 3 were treated respectively with aqueous extract at doses of 300 mg/kg and 600 mg/kg while groups 4 and 5 respectively received 300 mg/kg and 600 mg/kg ethanolic extract. The extracts were administered orally and the animals were sacrificed on the day 8 and the blood samples collected via retro-orbital plexus. The blood was then centrifuged after fifteen minutes and serum obtained for lipid profile analysis.  Results: The total cholesterol level generally decreased significantly (p < 0.05) in test groups, except in group 2 (0.502 ±.008 mg/dl) which received lower aqueous extract dose of 300 mg/kg. There was a significant decrease (p < 0.05) in triacylglycerol (TG) levels in groups of 2 and 3 (groups treated with aqueous extract) but indicated a significant (p < 0.05) increase in group 4 (0.15 ± .003 mg/dl) which received high ethanolic extract dose. The high density lipoprotein cholesterol (HDL-C) levels increased significantly (p < 0.05) in groups 4 and 5 with the mean values of 0.164 ± .002 mg/dl and 0.147 ± .004 mg/dl respectively. The mean values of the low density lipoprotein cholesterol (LDL-C) level generally indicated a significant (p < 0.05) decrease in all test groups, the decrease was more significant in groups 4 and 5 with mean values of 0.065 ± .00 mg/dl and 0.069 ± .00 mg/dl, when compared with groups 2 and 3. Conclusions: This study proves that both aqueous and ethanolic extracts of Datura stramonium possess anti-lipidaemic property. The ethanolic extract had higher anti-lipidaemic property than the aqueous extract. Both extracts might be useful in the treatement of some cancers and cardiovascular diseases.

AbstractBackground:This study assessed whether non-fasting lipid markers could be substituted for fasting markers in screening for dyslipidemia, whether direct measurement of non-fasting low-density lipoprotein cholesterol [LDL-C (D)] could be substituted for the calculation of fasting LDL-C [LDL-C (F)], and the utility of measuring non-high-density lipoprotein cholesterol (non-HDL-C).Methods:In 33 children, the lipid profile was measured in the non-fasting and fasting states within 24 h. Correlations were examined between non-fasting LDL-C (D) or non-HDL-C levels and fasting LDL-C (F) levels.Results:Non-fasting triglyceride (TG), total cholesterol (TC), HDL-C, LDL-C (D), and non-HDL-C levels were all significantly higher than the fasting levels, but the mean difference was within 10% (except for TG). Non-fasting LDL-C (D) and non-HDL-C levels were strongly correlated with the fasting LDL-C (F) levels.Conclusions:In conclusion, except for TG, non-fasting lipid parameters are useful when screening children for dyslipidemia. Direct measurement of non-fasting LDL-C and calculation of non-fasting non-HDL-C could replace the calculation of fasting LDL-C because of convenience.
