Although certain neoplasms are unique to man, others occur across species. One such neoplasm is bronchioloalveolar lung carcinoma (BAC), a neoplasm of the Type II pneumocyte that affects humans, sheep, and small animals (dogs and cats). Human BAC occurs largely in nonsmokers. Sheep BAC is caused by the jaagsiekte retrovirus and is endemic and contagious. Feline BAC is neither endemic nor contag...

OBJECTIVE We aimed to demonstrate the time-dependent ultrastructural changes in pneumocyte type II cells following brain injury, and to propose an electron microscopic scoring model for the damage. METHODS Forty Wistar-Albino female rats weighing 170-200 g were used. The rats were allocated into five groups. The first group was the control and the second was the craniotomy without trauma. The...

Cholera toxin (CT) stimulated DNA synthesis by low-density primary cultures of adult rat type II pneumocytes (T2P) in a dose-dependent manner, either in the presence or the absence of serum. In the presence of 1% rat serum, 1 microgram/ml CT also stimulated a 50% increase in cell number over 8 days of incubation (P<0.01); this was in addition to a 2-fold increase in cell number induced by the s...

BACKGROUND The main objective was to evaluate the protective effect of erythropoietin on lung ultrastructure against damage in rats after traumatic brain injury. METHODS We used forty Wistar-Albino female rats weighing 170-200 gr. The rats were allocated into five groups. The first group was the control and the second was the craniotomy without trauma. The third group was the trauma group. Th...

DNA methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. To assess DNA methylation pattern in different developmental stages of Aeluropus littoralis, methylation sensitive amplified polymorphism (MSAP) was used. Methylation and demethylation status at the CCGG recognition site were...

background: angiotensin i converting enzyme (ace) is a zinc metalloproteinase, converts ang-i to ang- ii, a pro-inflammatory agent which may contribute to pathophysiology of some diseases like type 2 diabetes. objective: to investigate the relationship between ace i/d polymorphism and type 2 diabetes in 261 iranian casecontrol pairs. methods: 170 patients (85 type 2 diabetics with nephropathy a...

Age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. Methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. The cells had greater affinity for diamine silver compared to methenamin...
