Serious contamination of aquatic systems by arsenic (As) in different parts of the world calls for the development of an in situ cost-effective phytoremediation technology. In the present investigation, plants of Hydrilla verticillata (L.f.) Royle were exposed to various concentrations of arsenate (As(V)) (0-250 microM) and arsenite (AsIII) (0-25 microM)(More)
pursuing the cloning of novel genes are often faced with the problem that only a partial protein sequence is known. Several procedures are commonly used involving the reverse translation of the protein sequence into a DNA sequence. These include synthesis of a short oligonucleotide sequence for screening libraries and of a primer pair for amplification of(More)
Lead exposure related oxidative stress has been incriminated, at least in part, to its toxic effects in different organs. The present investigation was carried out to study the ameliorative effects of antioxidant (ascorbic acid, alpha tocopherol or L-methionine) alone and antioxidant (alpha tocopherol) plus a conventional chelator (CaNa2 EDTA) on some of(More)
Antitrypanosomal activity of crude 50% ethanolic extract of Xanthium strumarium leaves was studied in vitro and in vivo. The extract exhibited trypanocidal activity at all four concentrations tested i.e. 5, 50, 500 and 1000 micrograms/ml, in vitro. In vivo trial revealed that the extract exerted antitrypanosomal effect at dosage of 100, 300 and 1000 mg/kg,(More)
The prophylactic efficacy of garlic (Allium sativum L.) extract to reduce tissue lead (Pb) concentration was evaluated experimentally in rats. Thirty female rats were divided into five groups, keeping group A as a healthy control. Rats of groups B, C, D and E received lead acetate orally at the rate of 5 mg per kg body weight daily for 6 weeks. The garlic(More)
Simulated pot experiments were conducted on four rice (Oryza sativa L.) genotypes (Triguna, IR-36, PNR-519, and IET-4786) to examine the effects of As(V) on amino acids and mineral nutrient status in grain along with antioxidant response to arsenic exposure. Rice genotypes responded differentially to As(V) exposure in terms of amino acids and antioxidant(More)
OBJECTIVE Present study was undertaken to evaluate the role of lipoprotein(a) in coronary heart disease (CHD) patients and its relationship with other established risk factors. METHODS Blood samples of 67 control patients (non-cardiovascular problems) and 222 CHD patients (> or = 4 weeks post myocardial infarction) were analyzed. Lipoprotein(a) was(More)
Hypoglycaemic, antihyperglycaemic and hypolipidemic activities of the aqueous and 50% ethanolic extracts of Caesalpinia bonducella Fleming (Leguminosae) seeds were studied in normal and streptozotocin (SZ)-diabetic rats. In normal rats, both the extracts exhibited hypoglycaemic activity as early as 4 h after administration at a lower dose of 100 mg/kg. The(More)
Ancient Indian physicians used the powdered tree bark of Terminalia arjuna Wight & Arn. for alleviating "hritshool" (angina) and other cardiovascular conditions. Its stem bark possesses glycosides, large quantities of flavonoids, tannins and minerals. Flavonoids have been detected to exert antioxidant, anti-inflammatory and lipid lowering effects while(More)
Signs of dental discolouration, difficulty in mastication, bony lesions, lameness, debility and mortality in domesticated animals, reared around superphosphate fertiliser plants located approximately 15 km north of Udaipur, Rajasthan prompted us to investigate for the occurrence of fluorosis. Out of 166 animals clinically examined, the prevalence rate was(More)
