Primer estudio En el marco de un estudio sobre los aadenocarcinomas de pulmón en gallinas ponedoras de edad avanzada, se realizó la necropsia de 150 gallinas ponedoras comerciales a los 3 años de edad. Se identificaron tumores en 67 de las gallinas. Los tumores metastásicos visibles en los pulmones de algunas aves hicieron que se recogieran los pulmones de 50 gallinas afectadas para su examen histológico. Se identificaron adenocarcinomas metastásicos en los pulmones de 9 de las 50 gallinas. El número de tumores y la extensión de la afectación del parénquima pulmonar variaban de mínima a extensa. Ocasionalmente se observaron émbolos tumorales en los vasos pulmonares. Se identificaron focos metastásicos con crecimiento expansivo o invasivo. Estos resultados indican que la propagación vascular de los adenocarcinomas es más común de lo que se pensaba en los pollos.Segundo estudio Las gallinas ponedoras de huevos marrones son muy susceptibles de padecer artropatía amiloidea como resultado de infecciones por Entercoccus faecalis y Mycoplasma synoviae. Otras bacterias frecuentemente asociadas son E. coli, Salmonella enteridis y Staphyloccus aureus, que se han asociado a la amiloidosis en pollos.

Primo studio Nell'ambito di uno studio sugli adenocarcinomi polmonari nelle galline ovaiole anziane, 150 galline commerciali che depongono uova sono state sottoposte a necroscopia a 3 anni di età. I tumori sono stati identificati in 67 delle galline. I tumori metastatici grossolanamente visibili nei polmoni di alcuni uccelli hanno richiesto la raccolta dei polmoni di 50 galline colpite per l'esame istologico. Gli adenocarcinomi metastatici sono stati identificati istologicamente nei polmoni di 9 delle 50 galline. Il numero di tumori e l'estensione del coinvolgimento del parenchima polmonare variava da minimo a esteso. Occasionalmente sono stati visti emboli tumorali nei vasi polmonari. Sono stati identificati focolai metastatici che mostravano una crescita espansiva o invasiva. Questi risultati indicano che la diffusione vascolare degli adenocarcinomi è più comune di quanto precedentemente pensato nei polli.Secondo studio Le galline brune che depongono le uova sono altamente suscettibili all'artropatia amiloide come risultato delle infezioni da Entercoccus faecalis e Mycoplasma synoviae. Altri batteri frequentemente associati includono E. coli, Salmonella enteridis, e Staphyloccus aureus sono stati associati all'amiloidosi nei polli.

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 parenchyme pulmonaire variaient de minime à étendue. Des emboles tumoraux ont été occasionnellement observés dans les vaisseaux pulmonaires. Des foyers métastatiques présentant une croissance expansive ou invasive ont été identifiés. Ces résultats indiquent que la propagation vasculaire des adénocarcinomes est plus fréquente qu'on ne le pensait auparavant chez les poulets.Deuxième étude Les poules brunes pondeuses sont très sensibles à l'arthropathie amyloïde à la suite d'infections par Entercoccus faecalis et Mycoplasma synoviae. D'autres bactéries fréquemment associées, notamment E. coli, Salmonella enteridis et Staphyloccus aureus, ont été associées à l'amyloïdose chez les poulets.

Erste Studie Im Rahmen einer Studie über Lungenadenokarzinome bei älteren Legehennen wurden 150 kommerzielle Legehühner im Alter von 3 Jahren seziert. Bei 67 der Hühner wurden Tumore festgestellt. Grob sichtbare metastatische Tumore in den Lungen einiger weniger Tiere veranlassten die Entnahme der Lungen von 50 betroffenen Hühnern zur histologischen Untersuchung. In der Lunge von 9 der 50 Hennen wurden histologisch metastatische Adenokarzinome festgestellt. Die Anzahl der Tumore und das Ausmaß des Befalls des Lungenparenchyms variierten von minimal bis extensiv. Gelegentlich wurden Tumorembolien in den Lungengefäßen festgestellt. Es wurden metastatische Herde mit expansivem oder invasivem Wachstum festgestellt. Diese Ergebnisse deuten darauf hin, dass die vaskuläre Ausbreitung von Adenokarzinomen bei Hühnern häufiger vorkommt als bisher angenommen.Zweite Studie Braune eierlegende Hühner sind sehr anfällig für Amyloid-Arthropathie als Folge von Infektionen mit Entercoccus faecalis und Mycoplasma synoviae. Weitere häufig assoziierte Bakterien sind E. coli, Salmonella enteridis und Staphyloccus aureus, die mit Amyloidose bei Hühnern in Verbindung gebracht wurden.

Primeiro Estudo Como parte de um estudo sobre os aadenocarcinomas pulmonares em galinhas poedeiras mais velhas, 150 galinhas comerciais poedeiras foram necropsiadas aos 3 anos de idade. Foram identificados tumores em 67 das galinhas. Tumores metastáticos grosseiramente visíveis nos pulmões de algumas aves provocaram a recolha de pulmões de 50 galinhas afectadas para exame histológico. Os adenocarcinomas metastáticos foram identificados histologicamente nos pulmões de 9 das 50 galinhas . O número de tumores e a extensão do envolvimento do parênquima pulmonar variou do mínimo ao extenso. Embolias tumorais foram ocasionalmente observadas em vasos pulmonares. Foram identificados focos metástáticos mostrando crescimento expansivo ou invasivo. Estas descobertas indicam que a propagação vascular dos adenocarcinomas é mais comum do que se pensava anteriormente em galinhas.Segundo Estudo As galinhas poedeiras de ovos castanhos são altamente susceptíveis à artropatia amilóide como resultado de infecções por Entercoccus faecalis e Mycoplasma synoviae. Outras bactérias frequentemente associadas incluem E. coli, Salmonella enteridis, e Staphyloccus aureus têm sido associadas à amiloidose em galinhas.

An experiment was conducted to diagnose histopathologic effects due to exposed to oral potentiated sulfonamide administration of in rats. 40 rats were randomly assigned into four equal groups (A, B, C and D) and were fed with standard pellet throughout the experimental period of 60 days. Rats of Group A were fed only with pellet without any experimental diet and were defined as control. Rats of Group B were treated with potentiated sulfonamide 80 mg/rat/day orally whereas. Group C was treated with potentiated sulfonamide 90 mg/rat/day orally. In Group D, potentiated sulfonamide were given through feed 100 mg/rat/day and respectively. Histopathology of kidney, liver, heart, lung, spleen, testis and sciatic nerve was done at the end of experiment (60 days) to showed any changes may be found in these organs.

Toxicity could be a direct effect on testes and reduction in spermatogonia and Leydig cells. Due to use of chemical toxins in farms and considering the data we obtained in this study, it is proposed that the application of toxin type, amount and time need to be carried out with careful planning and thoughtful management. Another pathway forPesticides can damage reproductive systems in species and these damages are complicated via complicated mechanisms. Hormonal disturbance might be one of these mechanisms and, considering the role of hormonal homeostasis in reproduction, we can conclude that these toxins exert their adverse effects on the reproduction process via disturbing hormonal homeostasis. In this experimental study, 40 turkey chicks were randomly and equally distributed into four equal groups. The control group received feed without Carbaryl. and experimental (1,2 and 3) groups that received 20 and 40 and 80 mg/kg b.wt Carbaryl in the feed for 60 days. At the end of the experiment ,Tissue sections were prepared from pancreas to investigate possible changes occurring in in this organ.

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 foci showing expansive or invasive growth were identified. These findings indicate that vascular spread of adenocarcinomas is more common than previously thought in chickens.Second Study Brown egg-laying hens are highly susceptible to amyloid arthropathy as a result of Entercoccus faecalis and Mycoplasma synoviae infections. Other frequently associated bacteria include E. coli, Salmonella enteridis, and Staphyloccus aureus have been associated with amyloidosis in chickens.
