Different antibiotics were selected, two local brands and one multinational brand for the same antibiotic so that comparison will be quite easy. Antibiotics used during the research work were Ofixime (Cebosh, Megnet, Fixitile), Paramycin (Nebra, Eyebrex, Tobracin), Emoxicillin (Supramox, Polyxil, Ospamox). These antibiotics were checked for their potential as antibacterial agents against some gram positive and gram negative bacterial strains, by agar well diffusion method. Antibacterial activity was deliberated against five bacterial strains i-e Klebsiella pneumonia, E.Coli, Salmonella, Staphylococcus Aureus and Flavobacterium Aureus.

The objective of the research work was to determine the distributed level of Heavy metals like Copper (Cu), Zink (Zn). Iron (Fe), Lead (Pb) and Chromium (Cr) in the month of January -February 2013 at Baran Dam F.R Bannu. The recorded level of the values of all heavy metals in head, abdomen and tail in Labeocalbasu were Cr>Fe>Cu>Zn>Pb, Cu>Cr>Zn>Pb, Cr>Fe>Cu>Zn>Pb, in Labeoboga were Zn>Cr>Fe >Pb>Cu, Cr>Zn>Cu>Fe>Pb,Fe>Cr>Cu>Zn>Pb, in Notopterusnotopterus were Cr>Fe>Zn>Cu>Pb, Cu>Fe>Cr>Zn>Pb,Fe>Cu>Cr>Zn>Pb, in Mastacembelusarmtus were Fe>Cu>Cr>Zn>Pb,Cr>Cu>Fe>Zn>Pb, Cr>Zn>Cu>Pb  respectively. It indicate that Pb have the lowest concentration in all the organ of above except in head of Labeoboga fish species. Chromium was found unexpectedly in high amounts but its consumption limits were not set down yet in Labeocalbasu. The mean value for heavy metals were Zn (P
