Cardiovascular Risk Scoring of Hospitalized Chronic Kidney Disease Patients by Framingham Risk Score.

Patients with chronic kidney disease (CKD) are more likely to have complications due to cardiovascular diseases (CVD). This cross sectional descriptive study was conducted in the Department of Medicine and Nephrology, Chittagong Medical College (CMC), Chittagong, Bangladesh from June to December, 2014 and was performed to estimate the risk of cardiovascular events according to Framingham's Risk Score of CKD patients. In this research, 100 patients who was diagnosed as CKD and admitted in the Chittagong Medical College Hospital were enrolled. Estimated glomerular filtration rate (eGFR) was calculated with the MDRD formula. Cardiovascular risk factors were analyzed by Framinghams criteria and after compilation data were analyzed by SPSS-18.0. Among 100 patients, most of patients were under 60 years of age where males (56.0%) were more than females (44.0%). Framingham Cardiovascular Risk Score revealed that most of the male were at high risk group compared to female. Regarding different components of lipid profile with Framingham risk score, higher risk group had high mean total cholesterol (212.17mg/dl) and also low mean HDL level (38.58mg/dl). Patient with different stages of CKD with cardiovascular risk showed stage 5 CKD was 80%, stage 4 was 15.0% and rest 5 was at stage 3 and most were in low risk group (56.0%). There were significant positive correlations found in between age and serum total cholesterol level with the cardiovascular risk scoring but not with HDL and eGFR. The predominant cardiovascular risk factors were age, male gender, smoking and high serum total cholesterol.

Efficacy of aqueous extract of garlic & allicin in experimental shigellosis in rabbits.

The aqueous extract of garlic (Allium sativum) and allicin both showed significant in vitro antibacterial activity against isolates of multiple drug-resistant Shigella dysenteriae 1, Sh. flexneri Y, Sh. sonnei and enterotoxigenic Escherichia coli. The minimum inhibitory concentrations of the aqueous extract and allicin against Sh. flexneri Y were 5 and 0.4 microliters/ml, respectively. The two agents also showed promising in vivo antibacterial activity against Sh. flexneri Y when tested in the rabbit model of experimental shigellosis, fully curing the infected rabbits within 3 days. On the contrary, 4 of the 5 rabbits in the control group died within 48 h. The rectal swab of rabbits of the experimental groups became free of the challenge bacteria on the second day of treatment. The antibacterial activity against the challenge strain was observed in the sera of the treated rabbits with 30-60 min of administration of the agents. The LD50 values of the aqueous extract and allicin in mice were 173.78 ml/kg and 204.17 microliters/kg of body weight, respectively. At the therapeutic dose, the two agents did not show any adverse effects on the standard biochemical profile of blood.

In vitro testing of the leaf extracts of Lawsonia alba for antimicrobial properties.

Leaf extracts (chloroform, ethanol and aqueous extracts) of Lawsonia elba were tested in vitro for their antimicrobial activity against seventeen strains of pathogenic bacteria and twelve fungi including seven pathogenic strains. Each of the extract showed good activity against most of the strains tested. The sensitivity of the bacteria and fungi to the extracts was compared to that of ampicillin, tetracycline, co-trimoxazole and griseofulvin sensidiscs.

Antibacterial activity of clove extracts against phagogenic strains including clinically resistant isolates of Shigella and Vibrio cholerae.

Clove extracts (petroleum ether, chloroform and ethanol extracts) were tested in vitro for their antibacterial activity against forty isolates of pathogenic bacteria including clinically resistant (resistant to ampicillin and nalidixic acid) strains of twenty-five Shigella and four Vibrio cholerae. All of the isolates except Pseudomonas aeruginosa showed promising sensitivity to the extracts.
