Abstract Background Continuous increase in drug resistance has hindered the control of malaria infection and resulted in multi-drug-resistant parasite strains. This, therefore, intensifies the search for alternative treatments with no or less side effects. Several histone deacetylase inhibitors have been characterised to possess anti-malaria activity; however, their further development as anti-malaria agents has not recorded much success. The present study investigated the anti-plasmodial activity of sodium acetate in Plasmodium berghei-infected mice, aiming at finding a better alternative source of malaria chemotherapy. Methods Thirty female Swiss albino mice were randomly distributed into six groups. Groups A (uninfected control) and B (infected control) received only distilled water. Group C (artesunate control) were infected and treated orally with 4 mg/kg artesunate on the first day, and subsequently 2 mg/kg artesunate. Groups D, E and F were infected and orally treated with 50, 100 and 200 mg/kg sodium acetate, respectively. Results Sodium acetate significantly lowered parasitaemia (p<0.05) after 4 days post-treatment, and the parasite inhibition rate of 68.5% at 50 mg/kg compared favourably with the 73.3% rate of artesunate. Similarly, administration of 50 mg/kg sodium acetate improved serum total cholesterol relatively better than artesunate. Our results also revealed that sodium acetate does not interfere with liver function, as there was no significant difference (p>0.05) in the serum activities of aspartate aminotransferase and alanine aminotransferase in both infected treated and uninfected mice. Conclusions This study shows that sodium acetate may be a safe alternative source of anti-malaria drugs. Its effect on the serum total cholesterol also predicts its ability in correcting malaria-induced metabolic syndromes.

Introduction: Cigarette smoking is one of the major cause and established risk factor of premature death due to respiratory and cardiovascular illness worldwide. Risk of coronary heart disease is increased by two-to four folds in smoking and tobacco chewing. Smoking and tobacco chewing leads to change in the concentration of serum total cholesterol, triglycerides, LDL, VLDL and HDL. In our present study, the main objective was to assess the blood lipid profile among smokers and tobacco chewers to ascertain cardiovascular risk in Nepal. Methods: It was a hospital based case control study carried out using data retrieved from the register maintained in the Department of Biochemistry of Institute of Medicine Teaching Hospital, Kathmandu, Nepal between 1st January, 2008 and 31st December, 2009. Of the 150 subjects enrolled in this study, 50 were current smokers, 50 were tobacco chewers and 50 were normal healthy controls. The variables collected were age, gender, total cholesterol, triglycerides, HDL, LDL, VLDL. The One way ANOVA was used to examine the statistical significant difference between groups. Post Hoc test LSD used for the comparison of means of control versus case groups. A p-value of <0.05 (two-tailed) was used to establish statistical significance. Results: The mean values of serum total cholesterol (257.5±22.6 mg/dl), LDL (186.6±24.0 mg/dl), TG (139.4±39.8 mg/dl) were significantly higher in smokers when compared to controls. In contrast to that HDL (42.9±1.5 mg/dl) was lower when compared to controls (44.8±1.9mg/dl). The mean values for TG (141.5±34.9 mg/dl), total cholesterol (260.3 ±21.2 mg/dl), LDL (188.5±26.0 mg/dl) in tobacco chewers was significantly higher when compared to controls. Conclusions: The lipid profiles are raised in tobacco chewers and smokers which may lead to higher incidence of cardiovascular disease.  Medical Journal of Shree Birendra Hospital; January-June 2013/vol.12/Issue1/29-31DOI: http://dx.doi.org/10.3126/mjsbh.v12i1.9089

The present case control study was designed to determined the relationship between serum Total cholesterol, Low Density Lipoprotein (LDL), Triglycerides (TG) and Body Mass Index (BMI). The study was carried out in the Department of Biochemistry Chittagong Medical College during the period of January 2010- December 2010. Samples were collected from population of different area of Chittagong City Corporation of different occupations, age from 35- 60 years. The data were collected by a structured questionaries which includes age, sex, occupation, dietary habits, family history of hyperlipidemia and DM. BMI was calculated by standardized protocol. Population suffering from DM, renal diseases and other endocrine disease were excluded. A total of 105 subjects were included in this study. Among them 70 were considered as case ( whose BMI was 25 kg/m2) and 35 were considered as control ( whose BMI was < 25 Kg/ m2).Serum Total cholesterol, LDL-C, HDL-C and TG were measured in all samples in fasting state. Study showed that female were more obese than male,( 31.14 +2.23kg/m2 Vs 29.71 +2.69kg/mo), p= <0.05.Results showed that Serum TC(45%), LDL-C(65%), TG(70%) were significantly higher in cases than that of controls (p=<0.001).Serum HDL-C(35%) was significantly decreased in cases than that of controls (p=<0.001).Study showed that hypertriglyceridemia (70%) was the common lipid abnormality and then LDL-C (65%). Study revealed that there was no significant difference in lipid profile between male and female. Pearson's Correlation Coefficient showed that there were positive correlation between TC (r=0.234,p=<0.05), LDL-C (r=0.258,p=<0.01), TG (r=0.409,p=<0.001) and BMI, and was negative correlation between HDL-C(r= -0.403, p= <0.001) and BMI. So early detection and prevention of obesity and abnormal lipid profile can largely reduce morbidity and mortality and alleviate undue burden on our limited health budget.

Minor beta thalassemia is a disorder without any special symptom which only causes mild anemia. In thalassemic patients accelerated erythropoiesis and enhanced cholesterol consumption have been suggested as the dominant mechanism for low level of lipoproteins. Hyperlipidemia is a risk factor for cardiovascular diseases and hence, low level of serum lipids can act as a protective factor. Because of the differences between social, economic, cultural conditions, dietary habits and genetics patterns among Iranians with other nations, this survey was conducted to verify these parameters among our thalassemia minor subjects. This study was carried out on 100 thalassemia carriers and 200 normal controls. Blood samples were collected and the biochemical evaluation was performed for measuring serum total cholesterol, LDL, HDL, TG, VLD. Descriptive statistical tables, independent t-test, Mann- Whitney and Chi-square were used for analyzing the data. The average values of serum total cholesterol, TG, LDL, HDL and VLDL in thalassemia minor subjects were 163.63±34.28, 159.74±157.54, 90.97±23.94, 34.97±8.07 and 73.44±72.43 mg/dl respectively. Moreover, the mean levels of total cholesterol, TG, LDL, HDL and VLDL in normal subjects were 192.77±37.27, 155.67±109.58, 123.42±33.57, 38.02±15.6 and 71.57±50.5 mg/dl respectively. The amount of serum total cholesterol and LDL in thalassemia carriers was significantly lower than normal subjects that shows the potential decline of cardiovascular and brain vessels diseases among thalassemia minor subjects compared to control group while other factors between the two groups did not show any significant difference.

AbstractTo evaluate the risk factors for hypercholesterolemia, we examined 4,371 subjects (3,207 males and 1,164 females) who received medical checkups more than twice at an AMHTS in Tokyo during the period from 1976 through 1991; and whose serum total cholesterol was under 250 mg/dl. The mean follow-up duration was 6.6 years. A self-registering questionnaire was administered at the time of the health checkup. The endpoint of this study was the onset of hypercholesterolemia when the level of serum total cholesterol was 250 mg/dl and over. We compared two prognosis groups (normal and hypercholesterol) in terms of age, examination findings and lifestyle. After assessing each variable, we employed Cox's proportional hazards model analysis to determine the factors related to the occurrence of hypercholesterolemia. According to proportional hazards model analysis, total cholesterol, triglyceride and smoking at the beginning, and hypertension during the observation period were selected in males; and total cholesterol at the beginning and age were selected in females to determine the factors related to the occurrence of hypercholesterolemia.

Antioxidants are recommended to prevent and treat oxidative stress diseases. Plants are a balanced source of natural antioxidants, but the poor solubility of plant active molecules in aqueous media can be a problem for the formulation of pharmaceutical products. The potential of PlantCrystal technology is known to improve the extraction efficacy and antioxidant capacity (AOC) of different plants. However, it is not yet proved for plant waste. Black tea (BT) infusion is consumed worldwide and thus a huge amount of waste occurs as a result. Therefore, BT waste was recycled into PlantCrystals using small-scale bead milling. Their characteristics were compared with the bulk-materials and tea infusion, including particle size and antioxidant capacity (AOC) in-vitro. Waste PlantCrystals possessed a size of about 280 nm. Their AOC increased with decreasing size according to the DPPH (1,1-diphenyl-2-picrylhydrazyl) and ORAC (oxygen radical absorbance capacity) assays. The AOC of the waste increased about nine-fold upon nanonization, leading to a significantly higher AOC than the bulk-waste and showed no significant difference to the infusion and the used standard according to DPPH assay. Based on the results, it is confirmed that the PlantCrystal technology represents a natural, cost-effective plant-waste recycling method and presents an alternative source of antioxidant phenolic compounds.

Abstract Background Body composition predicts cardiovascular outcomes, but it is uncertain whether anthropometric measures can replace the more expensive serum total cholesterol for cardiovascular risk stratification in low resource settings. Purpose The purpose of the study was to compare the additive prognostic ability of serum total cholesterol with that of body mass index (BMI), waist/hip ratio (WHR), and estimated fat mass (EFM, calculated using a validated prediction equation), individually and combined. Methods We used data from the MORGAM (MONICA, Risk, Genetics, Archiving, and Monograph) Prospective Cohort Project, an international pooling of cardiovascular cohorts, to determine the relationship between anthropometric measures, serum cholesterol, and cardiovascular events, using multivariable Cox proportional-hazards regression analysis. We further investigated the ability of these measures to enhance prognostication beyond a simpler prediction model, consisting of age, sex, smoking status, systolic blood pressures, and country, using comparison of area under the receiver operating characteristics curve (AUCROC) derived from binary logistic regression models. The primary endpoint was major adverse cardiovascular events (MACE), defined as a composite of death from coronary heart disease, myocardial infarction, or stroke. Results The study population consisted of 52,188 apparently healthy subjects (56.3% men) aged 47±12 years ranging from 20 to 84, derived from 37 European cohorts, with baseline between 1982–2002 all followed for 10 years during which MACE occurred in 2465 (4.7%) subjects. All anthropometric measures (BMI: hazard ratio (HR) 1.04 [95% confidence interval (CI): 1.03–1.05] per kg/m2; WHR: HR 7.5 [4.0–14.0] per unit; EFM: HR 1.02 [1.01–1.02] per kg) as well as serum total cholesterol (HR 1.20 [1.16–1.24] per mmol/l) were significantly associated with MACE (P&lt;0.001 for all), independently of age, sex, smoking status, systolic blood pressures, and country. The addition of serum cholesterol significantly improved the predictive ability of the simple model (AUCROC 0.818 vs. 0.814, P&lt;0.001), as did the combination of WHR, BMI, and EFM (AUCROC 0.817 vs. 0.814, P=0.004). When assessed individually, BMI (AUCROC 0.816 vs. 0.814, P=0.004) and WHR (AUCROC 0.815 vs. 0.814, P=0.02) improved model performance, while EFM narrowly missed significance (AUCROC 0.815 vs. 0.814, P=0.06). There was no significant difference in the predictive ability of a model including serum cholesterol versus that including all three anthropometric measures (AUCROC 0.818 vs. 0.817, P=0.13). The figure shows the pertinent areas under the ROC curve in predicting MACE. Conclusion In this large population-based cohort study, the addition of a combination of anthropometric measures, i.e. BMI, WHR, and EFM, raised the predictive ability of a simple prognostic model comparable to that obtained by the addition of serum total cholesterol.
