A POLYCLONAL -ANTIBODY-IMMUNOPEROXIDASE-CONJUGATE FOR THE SPECIFIC DETECTION OF PORCINE CIRCOVIRUS TYPE 2 Rev Salud Anim.
Pérez,L.J.; Díaz de Arce,Heidy; Barrera,Maritza; Castell,Sara; Frías,María T.
Porcine circovirus 2 is nowadays accepted as the essential infectious agent of postweaning multisystemic wasting syndrome which causes severe economic losses in porcine production worldwide. The diagnosis of PMWS is a difficult task and must follow three criteria: (i) the presence of compatible clinical signs, (ii) the presence of characteristic microscopic histopathological lesions, and (iii) the presence of PCV2 within these lesions in moderate or high. The presence of PCV2 in lymphoid tissues must be demonstrated by in situ hybridization or immunohistochemical methods. The in situ hybridization is a more complex and expense compared to other diagnostic tools, on the other hand, one problem concerning the immunohistochemical methods for PMWS diagnostic...

Assessment of the Toxicity of Sub-chronic Low and High Doses of the Bio-insecticide Spinosad on the Liver, Kidney and the Cerebellum in Male Albino Mice BABT
El-Naggar,Sabry A; Eltantawi,Hala; Ibrahim,Mahrous A; Alm-Eldeen,Abeer.
ABSTRACT Spinosad (SPD) is a highly selective insect control product. However, it was reported that SPD has toxicity toward other non-target organisms. This study was conducted to address the toxic effect of two sub-chronic low and high doses; 35 and 350 mg/kg SPD on some biochemical, histological and immunohistochemical parameters of the liver, kidney and cerebellum. Thirty-six male Swiss mice were divided into three groups of 12 mice each; first group (G1) served as a control, second group (G2) received a low sub-chronic dose of SPD that is equal to 35 mg/kg, and third group (G3) received a high sub-chronic dose of SPD that is equal to 350 mg/kg. The results showed that mice which were received 350 mg/kg SPD showed a significant decrease in the body...

Distribution of Serotonin-immunoreactive Enterochromaffin Cells in the Gastrointestinal Tract of the Least Shrew (Cryptotis parva) International Journal of Morphology
Al-Tikriti,Mohammed S; Khamas,Wael; Chebolu,Seetha; Darmani,Nissar A.
Serotonin is an important neurotransmitter in the central (CNS) and peripheral (PNS) nervous systems. It is involved in a variety of physiological processes both in the gut and in the CNS. The present study examined the distribution of serotonin containing enterochromaffin cells in the gastrointestinal tract (GIT) of a vomit competent species, the least shrew. These cells were easily recognized by their globular granules stained with the H&E and serotonin immune-positive stain. The immunoreactive enterochromaffin cells (IERCs) were mainly confined to the basal portion of the glandular epithelium and were distributed throughout the shrew stomach, small and large intestine. None was found to be associated with the mucosal epithelial lining. Moreover,...

Uterine leiomyoma in chimpanzee (Pan troglodytes) Arq. Bras. Med. Vet. Zootec.
Silva,A.E.; Ocarino,N.M.; Cassali,G.D.; Nascimento,E.F.; Coradini,M.A.; Serakides,R..
Uma chimpanzé de 22 anos de idade foi necropsiada com histórico clínico de anorexia, vômitos freqüentes e desidratação conseqüentes à gastrite iatrogênica. Macroscopicamente, o útero apresentava-se aumentado de volume, com o lúmen totalmente ocluído por nódulos firmes, esbranquiçados e coalescentes que se estendiam para o miométrio. Histologicamente, os nódulos eram constituídos por leiomiócitos bem diferenciados dispostos em várias direções e com coloração característica pelo tricrômio de Gomori e Masson. Pela imunoistoquímica, as células neoplásicas apresentavam marcação forte e difusa de receptores para progesterona e estrógeno, assim como de actina alfa de músculo liso. Algumas células neoplásicas e o estroma apresentavam marcação para vimentina e...
