Detection of progressive and regressive phase and LINE-1 retrotransposon in transfected dogs with transmissible venereal tumor during chemotherapy.

Canine transmissible venereal tumor (CTVT) is a tumor that commonly occurs in genital and extragenital sites of both genders. Long interspersed nuclear elements (LINE-1) retrotransposon has a pivotal role in allogenic transfection among uncontrolled dog populations. This study aimed to perform pathomorphological, immunohistochemical, and polymerase chain reaction (PCR) evaluation of CTVT (n = 18) in transfected dogs during chemotherapy.

Histopathological and immunohistochemical studies of apocrine sweat gland adenocarcinomas in cats.

Seven adenocarcinomas of apocrine sweat glands among the 67 cutaneous tumours of cats were evaluated between 1980 and 2005. Histopathologically, three tumours were solid, tubular, tubular-ductal, tubular-cystic and papillar-cystic types were also diagnosed each one. Cuboidal and squamous epithelial cells surrounding the cystic lumina and their papillar extensions into the cyst lumens were evident in almost all tumour types.

The role of cytokines and growth factors in the pathophysiology of neonatal necrotizing enterocolitis (NEC) is not defined clearly yet. The aim of this study was to determine the effects of recombinant human granulocyte colony stimulating factor (G-CSF) on intestinal cells in hypoxia-induced experimental NEC in rats. The study was experimented on Sprague Dawley rat pups.

Chitosan microparticles containing plasmid DNA as potential oral gene delivery system.

The potential of chitosan as a polycationic gene carrier for oral administration has been explored since 1990s. Chitosan has been shown to effectively bind DNA in saline or acetic acid solution and protect DNA from nuclease degradation. In this study, pDNA (plasmid DNA) was encapsulated in chitosan microparticles.

Macro anatomical investigations of the cranial cervical ganglion in domestic pig (Sus scrofa domesticus).

In this study, the left and right cranial cervical ganglia (ganglion cervicale craniale) of eight young (four male, four female) domestic pigs weighing around 70-80 kg were inspected macro anatomically. The cranial cervical ganglion (CCG) was found cranio-ventrally of the distal ganglion of the vagus nerve, medial of the jugular process extremity, ventral of the atlas, dorsal of the epiglottis base and medial of the common root (CR) established by the internal carotid and occipital arteries. The internal carotid nerve and jugular nerve ramified from the cranial part of CCG.

This study has been conducted on the knee joints of the New Zealand rabbits. A total of 20 knee joints from 10 (five female, five male) adult New Zealand rabbits were studied in the study. Fourteen ligaments and four sesamoid bones including the patellar bone, the infrapatellar adipose body, and the suprapatellar cartilage specifically present in rabbits were grossly observed.

[The beneficial effect of selenium against induction of squamous cell carcinoma of the tongue in rabbits].

Objectives: In a rabbit model of squamous cell carcinoma of the tongue, we monitored histopathologic changes and assessed the effect of selenium against carcinogenesis.

Study Design: The study included 36 male albino New Zealand rabbits. To induce squamous cell carcinoma of the tongue, 9,10-dimethyl-1,2-benzanthracene (DMBA)-acetone solution was applied three times a week for a duration of 20 weeks under anesthesia with xylazine hydrochloride and ketamine.

Ligand-induced expression of peroxisome proliferator-activated receptor alpha and activation of fatty acid oxidation enzymes in fatty liver.

Background: Peroxisome proliferator-activated receptor alpha (PPARalpha) regulates lipid metabolism upon activation by ligands. Peroxisome proliferator-activated receptor alpha may play a role in the pathogenesis of fatty liver disease. The aim of this study was to assess the PPARalpha expression pattern and mitochondrial/peroxisomal enzyme activities in response to high fat diet (HFD) and clofibrate, a well known PPARalpha ligand.

Subgross investigation of vessels originating from arcus aortae in guinea-pig (Cavia porcellus).

The vessels that originate from the aortic arch were studied in 16 adult guinea-pigs. Two major vessels, the left subclavian artery and the brachiocephalic trunk, were easily identified as they were branching off from the aortic arch. The brachiocephalic trunk, at first branched off to the left common carotid artery and continued as a common trunk, which was then divided into the right subclavian artery and the right common carotid artery.

The eustachian tube caliber and craniofacial skeleton in guinea pigs.

The temporal bone and eustachian tube (ET) keep developing up to adulthood in conjunction with facial growth, and the researchers considered that insufficient tubal function in childhood might be related to size, shape and position of the ET. In this study, we performed correlation and stepwise regression analyses between craniofacial skeletal parameters and diameter of the cartilaginous ET in 90 guinea pigs. Data showed that, not the potency of the lumen at the superior part of the cartilaginous ET, but the configuration of the cartilage surrounding the superior part of the ET, and position of the lateral lamina appeared to be significantly associated with the balance of the growth potentials between the naso-premaxillary unit, maxillo-zygomatic unit and the anterior cranial base.

Detection of Mycoplasma ovipneumoniae and Pasteurella haemolytica antigens by an immunoperoxidase technique in pneumonic ovine lungs.

Four hundred twenty pneumonic lungs from lambs were examined for Mycoplasma ovipneumoniae and Pasteurella haemolytica by an immunoperoxidase technique using an extravidin-biotin-peroxidase complex method in formalin-fixed, paraffin-embedded sections. Histologic examination of tissue sections revealed strong positive reactions in 60.9% and 68.

Canine gastritis associated with Helicobacter felis.

Naturally occurring gastritis associated with Helicobacter felis was detected in two dogs. Histologically, chronic changes characterized by lymphofollicular aggregation were observed. Ultrastructurally, organisms located on the mucosal surface, within gastric pits and glandular epithelial cells.

Helicobacter felis as a cofactor alone or together with stress in cryptosporidial activation in mice.

Cryptosporidiosis is caused by a protozoan parasite, mainly found in animals, which usually results in transient, mild gastroenteritis in humans but can cause severe and prolonged disease in immunocompromised individuals. Immunocompetent mice, naturally infected with Cryptosporidium muris, were used to investigate the effects of inoculation with Helicobacter felis and of stress on the activity of the C. muris infection, as indicated by histopathological examination of their stomachs.
