ABSTRACT
Background: Obesity and overweight is a disorder of unusually increased body fat generally resulting from increased energy intake relative to energy expenditure and is a primary sustenance-related disorder globally. The extensive increase in its prevalence in current years and its association with reduced life expectancy has made obesity one of the most vital public health problems. The purpose of the study was to determine the relationship between serum lipid profile and blood pressure with body mass index (BMI). Material & Methods: A cross-sectional study was carried out in the Department of Physiology and Biochemistry, Rangpur Medical College, Rangpur from January 2013 to December 2013. A purposive sampling technique was followed. A total number of 90 people from 18 to 45 years old were included in the study, categorized into three groups, such as Group-A:(Control 30): Healthy subject of normal weight, Group-B:(Experimental 30): Healthy subject of overweight & Group-C(Experimental-30): Healthy subjects of obese. Verbal consent was taken before recruiting the study population. Completed data forms were reviewed, edited, and processed for computer data entry. The data analysis was performed using the “t” test, “r” test & Statistical Package for the Social Sciences (SPSS) Version 25.0. Results: In group A, the mean BMI of patients was 18.5-22.9, in group B mean BMI of patients was 23.0-24.9, and in group C, the mean BMI of people was 25.0 or greater. The mean ± SD serum LDL-C levels were 107.77 ± 26.720 mg/dl in group A and 134.70 ± 41.787 mg/dl in group B. There was a significant difference (p<0.001) between the two groups. The mean ± SD pulse pressure levels were 38 ± 6.644 mmHg in group A and 41.67 ± 11.167 mmHg in group B. There was no significant difference (p>0.05) between the two groups. Serum total cholesterol levels were positively correlated in groups A & B but the relationship of serum total cholesterol levels was statistically significant in groups A and B. Blood pressure levels were positively correlated in groups A &C but the relationship was statistically non-significant. Conclusion: In this current content, it is difficult to define the specific mechanism involved for significantly higher serum total cholesterol, serum triglyceride, and serum LDL-C levels and non-significantly lesser serum HDL-C levels in overweight & obese people and also non-significantly higher blood pressure in overweight people but significantly higher blood pressure in obese subjects.
ABSTRACT
Aims: This research investigated the thrombolytic, cytotoxic and antidiabetic effects of Paederia foetida leaf methanol extract. Place and Duration of Study: Department of Genetic Engineering and Biotechnology and Department of Biochemistry and Molecular Biology, University of Chittagong, Bangladesh, between April to December, 2012. Methodology: An in-vitro thrombolytic model was used to check the thrombolytic effect of Paederia foetida extract using streptokinase as a positive control. Cytotoxic effect was measured by Brine shrimp lethality bioassay. Antidiabetic effect of the extract was conducted in alloxan induced diabetic model of Swiss albino mice. Data were analyzed by one way ANOVA using statistical package for social science (SPSS) software. Results: In in-vitro thrombolysis, Paederia foetida extract (100μl) lysed 21.40 ± 1.39 %, Streptokinase (positive control) 81.42 ± 0.88 % and water (negative control) 4.63 ± 0.31% of the blood clots. These clot lysis values were statistically different (p<0.05) from each other. In Brine shrimp bioassay, lethal concentration (LC50) of Paederia foetida extract was found 65.31 μg/mL which was statistically significant compared to Vincristine sulfate (positive control, LC50=0.76 μg/mL). The extract showed a significant and dosedependent decrease in blood glucose level in alloxan induced diabetic mice. The effect of the extract was comparable to the reference antidiabetic drug metformin (150 mg/kg BW). Conclusion: The results demonstrated a moderate thrombolytic, cytotoxic and antidiabetic effect of Paederia foetida leaf extract to be analyzed further for prospective pharmaceutical preparation.
ABSTRACT
Clausena suffruticosa (Family: Rutaceae) root ethanolic extract was subjected to analyze for its antioxidant effect by DPPH free radical scavenging method, antibacterial & antifungal effect by disc diffusion technique and cytotoxic effect by brine shrimp lethality test. The extract showed very significant antioxidant activity with the LC50 value of 3.28μg/ml. In antibacterial screening, moderate zone of inhibition (7.5-9.0mm in diameter) was observed against gram positive Bacillus subtilis, Bacillus cereus, Streptococcus aureus, Bacillus polymyxa & Bacillus megaterium and promising zone of inhibition (10.0-13.0mm in diameter) against gram negative Salmonella typhi, Shigella flexneri,, Proteus sp. & Escherichia coli. Klebsiella sp. and Shigella sonnei did not show sensitivity. The MIC values against these bacteria were ranged from 3,000 to 4,500μg/ml. Root extract showed significant zone of inhibition against Aspergillus ustus, Aspergillus niger and Aspergillus ochraceus in antifungal assay. In the cytotoxicity assay, LD50 and Chi-square value of the ethanolic extract against brine shrimp nauplii were 546.94μg/ml and 1.9932 demonstrating potent cytotoxic effect of the extract.
