Effect of pollution on DNA damage and essential fatty acid profile in Cirrhinus mrigala from River Chenab

The objective of this study was to evaluate the eff ect of anthropogenic pollution on DNA
damage and the fatty acid profi le of the bottom dweller fi sh ( Cirrhinus mrigala ), collected from the River
Chenab, in order to assess the eff ect of the toxicants on the quality of the fi sh meat. The levels of Cd, Hg, Cu,
Mn, Zn, Pb, Cr and Sn and of phenols from this river were signifi cantly higher than the permissible limits
set by the USEPA. Comet assays showed DNA damage in Cirrhinus mrigala collected from three diff erent

First report on fish cysteine as a biomarker of contamination in the River Chenab, Pakistan

The eastern and southern parts of the Faisalabad
city produce considerable quantities of industrial and municipal
pollutants, much of which is drained into the River
Chenab, reducing the productivity of fauna and flora in the
river. This study was aimed to determine whether cysteine is
useful as a biomarker of exposure to polluted fresh water. The
amino acid profile of fish muscle was analyzed by paper chromatography
in Cirrhinus mrigala and Labeo rohita from the
River Chenab to determine habitat related variations due to the

Histological changes in the digestive tract of striped murrel larvae during ontogeny

In this study, the ontogeny of the digestive tract was studied histologically in striped murrel Channa striatus from

hatching to 25 days post-hatching (DPH). At hatching, the digestive tract of striped murrelconsisted of a straight tube

dorsally attached to the yolk sac. St 2 DPH, the mouth opened, oral valves were visible and taste buds were detected

between 2 and 3 DPH. During this period, intestine was differentiated into the anterior and posterior intestine, and the

Ecological aspects of the horned viper, Cerastes cerastes gasperettii in the central region of Saudi Arabia

Feeding ecology of any species can help us to understand its natural history, ecological

requirements and approaches involved in searching for food. Feeding ecology and sexual dimorphism

in the horned viper, Cerastes cerastes gasperetti collected from the Al-Thumama area, central

region of Saudi Arabia was described. The gut content of Cerastes c. gasperetti mainly consisted of

rodents (70%) in addition to arthropods (15%) and lizards (10%). Least sexual size dimorphism

Cerastes cerastes gasperettii venom Induced Hematological Alterations and Oxidative Stress in Male Mice

The desert horned vipers (Cerastes cerastes gasperettii; C. c. gasperettii) are

the most familiar snakes of the great deserts of North Africa and the Middle East, including

the Saudi Arabia. They are responsible for many human snake bites. The current study

was designed to investigate the hematological effects and oxidative stress induction in

lung, heart and spleen after C. c. gasperettii envenomation. Thirty six male Swiss albino

mice were randomly divided into 2 groups, Control group injected intrapretoneally (i.p.)
