Keeping in view the effects of industrial effluents mainly the bio-accumulative heavy metals on plants, we propose the present study. Experiments showed increasing concentrations of lead acetate treatments suppress germination of Bengal gram seeds. Root development in control seeds were appropriate compared to the seeds in 1mM concentration whereas seeds in 2mM and 4mM were more affected by lea...

The objective of present study was to investigate the effects of aqueous garlic extracts, vitamin E and N-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. Twenty-five male rats were divided into five groups. Animals within different treatment groups were maintained on their respective diets for 35 days as follows: grou...

The aim of this work was to study the effects of sub-lethal exposure of lead acetate on the histopathology of the gills, liver, kidney and muscle and its accumulation in these organs of Clarias gariepinus. Results showed that lead accumulation in the tissues of C. gariepinus was dependent on the exposure period and lead concentration. Gills and liver were the predominant storage tissue and the ...

Chronic exposure to lead (Pb) affects neural functions in central nervous system (CNS) particularly the learning and memory. On the other hand, alteration of calcium level in the CNS results in activation of NOS. It has been shown that lead enters the neurons through calcium channels and displaces Ca2+ from calcium binding proteins such as calmodulin and troponin C thereby affecting calcium-med...

We investigated the effects of lead exposure during the pre- and postnatal period on the neurobehavioral development of female Wistar rats (70-75 days of age, 120-150 g) using a protocol of lead intoxication that does not affect weight gain. Wistar rats were submitted to lead acetate intoxication by giving their dams 1.0 mM lead acetate. Control dams received deionized water. Growth and neuromo...

Lead poisoning often prevails in children and industrial workers. The present study was undertaken to evaluate the effects of lead acetate on steroidogenic functions of testis, serum levels of gonadotrophins and testosterone in albino rats. Testicular steroidogenic activity was evaluated by measuring the activities of two steroidogenic key enzymes, Delta5-3beta hydroxysteroid dehydrogenase (Del...

Objective(s) During recent years, there has been an increasing interest in contribution of environmental pollutants as heavy metals to human male infertility. Present study was aimed to investigate the effects of maternal lead acetate exposure during lactation on postnatal development of testis in offspring rats. Materials and Methods A total of 60 female rats randomly divided into four equa...

Serotyping is not sufficient to differentiate between Salmonella species that cause paratyphoid fever from the strains that cause milder gastroenteritis as these organisms share the same serotype Salmonella Paratyphi B (S. Paratyphi B). Strains causing paratyphoid fever do not ferment d-tartrate and this key feature was used in this study to determine the prevalence of these strains among the c...
