Knowledge, Attitude and Practice Regarding Pharmacovigilance and Consumer Pharmacovigilance among Consumers at Lalitpur District, Nepal.

BACKGROUND: Adverse drug reactions (ADRs) can be a big threat to the health of people in Nepal as a variety of medicines are consumed in the country. Involving consumers in pharmacovigilance can strengthen ADR reporting. The study aims to find out knowledge, attitude and practice regarding pharmacovigilance and consumer pharmacovigilance among consumers at Lalitpur district, Nepal Methods: It was carried out in outpatients visiting in KIST Medical College and Teaching Hospital, Lalitpur, Nepal. Participant's knowledge, attitude and practice were measured by noting their agreement with a set of 21 statements along with multiple choice and open ended questions. RESULTS: A total of 157 outpatients were surveyed. The knowledge scores for males (12) was better compared to the females (11), but the scores for attitude and practice were same for both groups. The maximum score for knowledge was 29, attitude was 6 and practice was 10. The overall KAP scores was 45. The total scores for knowledge, attitude and practice for males (24) were better compared to female (22) respondents. Seventy-one patients (68%) who participated in this study favoured establishing a consumer centre for obtaining information about ADRs. CONCLUSIONS: Knowledge scores among consumers regarding pharmacovigilance is low and require advocacy and improvement.

Effect of ethanol on experimental inflammatory models.

Ethanol (2 g/kg i.p.) caused insignificant increase in carrageenan induced oedema with a single dose and significant increase in oedema when given once daily for five days prior to the induction of inflammation. In other sets of the experiment ethanol (2 g/kg i.p., O.D.) was administered for three days in rats in which formaldehyde-induced arthritis was produced, and for seven days in rats in which cotton pellets were implanted. There was no significant change in formaldehyde-induced arthritis and cotton pellet granuloma formation in control as well as ethanol-treated animals except that a significant decrease in formaldehyde-induced arthritis was observed at 48 hours. The results have been discussed and it is suggested that an increase in amino acid pool after the exogenous administration of amino acid may play a role in acute inflammation but not in subacute and chronic inflammation.

Persistent Cloaca associated with Unilateral Lung Agenesis- A Rare Presentation.

We report a case of full term female child having persistent cloaca who was diagnosed to have right lung agenesis on investigations.

Evaluation of diuretic activity of different extracts of Mimosa pudica Linn.

In that study, Mimosa pudica linn was tested for diuretic activity using the lipschitz test. The ethanolic and aqoues extract of Mimosa pudica Linn. was studied at two dose level 100 and 200 mg kg(-1) b.wt. Furosemide (20 mg kg(-1) b.wt.) was used as standard drug in a 0.9% saline solution. Urine volumes were measured for all the groups up to 5 h. The ethanolic extract of Mimosa pudica linn was exhibited significant diuretic activity at doses of 100 and 200 mg kg(-1) b.wt. by increasing total urine volume and ion concentration of Na+ k+ and Cl-.

Lipid content and fatty acid composition in N2-fixing cyanobacterium Anabaena doliolum as affected by molybdenum deficiency.

Anabaena doliolum grown under molybdenum deficiency produced less biomass (on a dry wt basis) and the cells had lower protein content but higher carbohydrate content than Mo-grown material. Molybdenum deficiency led to a slight decrease in chlorophyll a, a 1.5-fold increase in carotenoids and a 1.4-fold increase in total lipid but there was no difference in the lipid profiles of Mo-enriched and Mo-deficient cells. Molybdenum deficiency caused increases in the cell contents of digalactosyl diacylglycerol and phosphatidylglycerol and decreases in monogalactosyl diacylglycerol and sulphoquinovosyl diacylglycerol lipids. The concentration of unsaturated C18 fatty acids was lower in the Mo-deficient cells.

Accelerated tissue aging and increased oxidative stress in broiler chickens fed allopurinol.

Uric acid has been hypothesized as being one of the more important antioxidants in limiting the accumulation of glycosylated endproducts in birds. Study 1 was designed to quantitatively manipulate the plasma concentrations of uric acid using hemin and allopurinol while study 2 determined their effects on skin pentosidine, the shear force value of Pectoralis major muscle, plasma glucose, body weight and chemiluminescence monitored oxidative stress in broiler chickens. Hemin was hypothesized to raise uric acid concentrations thereby lowering oxidative stress whereas allopurinol was hypothesized to lower uric acid concentrations and raise measures of oxidative stress. In study 1 feeding allopurinol (10 mg/kg body weight) to 8-week-old broiler chicks (n=50) for 10 days decreased plasma uric acid by 57%. However, hemin (10 mg/kg body weight) increased uric acid concentrations 20%. In study 2, 12-week-old broiler chicks (n=90) were randomly assigned to either an ad libitum (AL) diet or a diet restricted (DR) group. Each group was further divided into three treatments (control, allopurinol or hemin fed). Unexpectedly, hemin did not significantly effect uric acid concentrations but increased (P<0.05) measures of chemiluminescence dependent oxidative stress in both the DR and AL birds probably due to the ability of iron to generate oxygen radicals. Allopurinol lowered concentrations of uric acid and increased (P<0.05) the oxidative stress in the AL birds at week 22, reduced (P<0.05) body weight in both the AL and DR fed birds at 16 and 22 weeks of age, and markedly increased (P<0.001) shear force values of the pectoralis major muscle. Skin pentosidine levels increased (P<0.05) in AL birds fed allopurinol or hemin fed birds, but not in the diet restricted birds at 22 weeks. The significance of these studies is that concentrations of plasma uric acid can be related to measures of oxidative stress, which can be linked to tissue aging.
