First Study As part of a study on lung aadenocarcinomas in older laying hens, 150 commercial egg-laying chickens were necropsied at 3 years of age. Tumors were identified in 67 of the hens. Grossly visible metastatic tumors in the lungs of a few birds prompted collection of lungs from 50 affected hens for histologic examination. Metastatic adenocarcinomas were identified histologically in the lungs of 9 of the 50 hens . The number of tumors and extent of involvement of the lung parenchyma varied from minimal to extensive. Tumor emboli were occasionally seen in pulmonary vessels. Metastatic...

Première étude Dans le cadre d'une étude sur les aadénocarcinomes pulmonaires chez les poules pondeuses âgées, 150 poules pondeuses commerciales ont été autopsiées à l'âge de 3 ans. Des tumeurs ont été identifiées chez 67 des poules. Des tumeurs métastatiques grossièrement visibles dans les poumons de quelques oiseaux ont incité à prélever les poumons de 50 poules affectées pour un examen histologique. Des adénocarcinomes métastatiques ont été identifiés histologiquement dans les poumons de 9 des 50 poules. Le nombre de tumeurs et l'étendue de l'atteinte du...

Cypermethrin might present a risk to the human health and environment, due to its wide use in many fields. In this experimental study, 40 mice were randomly and equally distributed into four equal groups. The control group without Cypermethrin and experimental (1,2 and 3) groups that received 5 and 10 and 20 mg/kg per day by oral gavage for 30 days. At the end of the experiment, Tissue sections were prepared from testis and pituitary gland to investigate possible changes occurring in in this organ.
