Abstract: The aim of the study was to observe parasitic effect on lipase and glucose content in the tissue of artificially infested host pigeon with cestode parasites. Gastro-intestinal tract associated organs were extracted from the body cavity of dissected animal. Gizzard, liver, spleen, pancreas were separated and preserved. Thereafter, Lipase and glucose determination was carried out from these organs.

It was observed that parasitic infection decreased lipase in liver and spleen while increased in pancreas. Higher lipase content was measured in infected animal’s crop a lesser content was measured in gizzard. It was also observed that infection impaired glucose level in intestine and other organs as well. Parasitic infections enhanced the glucose level in intestine and crop, while decreased glucose level in spleen, pancreas and liver.

Keywords: Parasitic Infection effects, Glucose, Lipase, Pigeon Columba livia.

Abstract: Radon concentration and its exhalation rate has been measured from twenty five soil samples collected from seven different locations of Dera Ismail Khan, in the north west of Pakistan. These samples were crushed after drying and passed through sieves with different sizes of pores to get three grain sizes, £0.595 mm, 0.595-2.00 mm and 2.00-4.00 mm of soil. CR-39 based NRPB (National Radiological Protection Board) radon dosimeters have been used to measure the radon concentration and exhalation rates. The maximum average value of radon exhalation rate has found to be: (3.57±0.38) Bq m-2 hr-1 in the samples having grain size 2.00-4.00 mm and the minimum as: (2.21±0.26) Bq m-2 hr-1, in the samples with grain size £ 0.0595 mm. This indicates that the radon exhalation rate increases with the grain size. The maximum average value of radon exhalation rate has been found in samples collected from river side where soil texture is silty clay loam. The obtained values of radon exhalation rate for all the samples are well below the world average value of 57.60 Bq m-2 hr-1.

Keywords: Radon concentration, Radon exhalation rate, grain size, soil texture.
