Group A, rats were fed normal basal diet only. Group B rats were placed on normal basal, mixed with cadmium chloride (3 mg/kg body weight daily) while group C rats were fed with basal diet mixed with Cadmium chloride (3 mg/kg body weight) and 0.5...
The correlation between the malignant proliferation on cholangiocarcinoma cell lines and in bile from Helicobacter pylori infected patients with biliary tract stones
July 2010
Helicobacter pylori has been detected in human tissue and is a candidate for etiologic investigations on the causes of hepatic and biliary tract diseases, but reliable serologic tests need to be developed in order to pursue such investigations. The aim of this study was to assess the correlation between the infection of H. pylori in bile from patients with biliary tract stones and the proliferation of...

This study correlates and presents the findings of the concentrations of fluorides – an important contaminant of ground water – present in two specific locations: The Ex-Hacienda well, which supplies the community of San Miguel Vindhó; and the Manzanitas-I well, which supplies La Malinche. The study concentrates on the prevalence and severity of dental fluorosis in students between 12 to 15 years old,...
Effect of Hibiscus sabdariffa anthocyanins on 2, 4-dinitrophenylhydrazine-induced tissue damage in rabbits
April 2010
This study examines the effects of anthocyanin extract of the dried calyces of Hibiscus sabdariffa Linn. on the 2, 4 -dinitrophenylhydrazine (2, 4 -DNPH)-induced cytotoxic effects in rabbits. Twenty male adult rabbits used for the study were divided into four groups. Group 1, the control took only water while animals in groups 2 and 4 received 100 mg/kg body weight of the anthocyanin extract of H....
Wastewater COD removal using sol-gel immobilized humic acid
April 2010
In this study, humic acid which contains both hydrophobic and hydrophilic moieties is successfully entrapped in sol-gel matrix which is used to reduce the chemical oxygen demand (COD) of Gaza wastewater. The method was very efficient in which more than 90% reduction of the COD had been achieved, it was found that contact time with the matrix, temperature, pH, particles size, adsorbent dose, and agitation speed effect...
Organic pollution from the Songhua River induces NIH 3T3 cell transformation: Potential risks for human health
December 2009
Epidemiological investigation has shown that organic contamination of the Songhua River is a risk factor for tumor development among residents who live nearby. A mutagenesis is induced by organic contamination using short-term genotoxic bio-assays. To further investigate the risk of carcinogenic potential to human health, the NIH3T3 cell line was used to examine the induction of transformation by diethyl...
Comparative nephrotoxic effect associated with exposure to diesel and gasoline vapours in rats
December 2009
Comparative effect of exposure to 20.7 ± 5.8 cm3 h-1kg-1m-3 day-1 of diesel and gasoline vapours on the kidney functions was assessed in rats. It was observed that exposure to diesel and gasoline vapours produced a significant increase (P < 0.05) in serum creatinine, urea, BUN, uric acid, glucose and K+; and a significant decrease (P < 0.05) in serum Na+ and Cl- levels. However, the percentage...
Contamination profile of major rivers along the highways in Ondo State, Nigeria
August 2009
The quality of major rivers (Oluwa, Owena, Ogbese and Ose) along the highways in Ondo state, Nigeria were investigated using water, surface sediment and African catfish, Clarias gariepinus, as environmental indicators. Results from the study revealed that some of the water quality constituents exceeded the World Health Organization (WHO) standards for drinking water and water meant for other recreational...

Prevention of renal toxicity from lead exposure by oral administration of Lycopersicon esculentum
July 2009
For decades, lead (Pb) has being known for its adverse effects on various body organs and systems. In the present study, the ability of Pb to lower renal clearance (RC), as an index of renal function, was investigated and tomato (Lycopersicon esculentum: source of antioxidants) paste (TP) was administered orally to prevent the Pb’s adverse effects. 54 Sprague Dawley rats, randomly divided into 3...
Association of interleukin 27 expression and p28 gene polymorphism with chronic hepatitis B virus infection
July 2009
Interleukin 27 (IL-27) is a newly discovered cytokine encoded by 2 genes, EBI3 and p28. We investigated IL-27 serum levels and p28 gene -964 A>G polymorphism in patients with chronic HBV infection and in healthy individuals, with the aims to define the correlation between IL-27 expression and chronic hepatitis B development. 168 patients, 99 recovered individuals and 152 healthy individuals...
Studies on the pollution potential of wastewater from textile processing factories in Kaduna, Nigeria
July 2009
Samples of effluents from 3 textile processing factories F(1), F(2) and F(3), were characterized for their pollution potential. The concentrations of solids were found to be 1020, 790 and 1,380 mg/l total solids for the factories 1, 2 and 3, respectively. The BOD’s and COD’s were 342.8 and 542.4 mg/l for F(1), 123.2 and 224.6mg/l for F(2) and 456 and 738.4mg/l for F(3). The pH for the effluents...
Characterization of industrial waste and identification of potential micro-organism degrading tributyl phosphate
June 2009
The present research study has been carried out in the waste disposal site for characterization of physical, chemical and biological parameters to assess the microbial consortium present in the contaminated site and to isolate the potential microorganism for biodegradation of Tributyl Phosphate. The ambient conditions present in the contaminated site shows the values: pH (6.61), Temperature (35.6), Moisture (50.72%),...
Hydroxocobalamin (vit b12a) effectively reduced extent of cyanide poisoning arising from oral amygdalin ingestion in rats
