The objective of this study was to evaluate the histopathologic and immunohistochemical effects of propineb on rat nasal mucosa. Twenty adult Sprague-Dawley rats weighing 180­220 g, were used as experimental animals. The rats were divided into propineb and control groups. The control group received distilled water with spray at the same time period. The experiment was terminated after three weeks. In each case, sections of the nosewere taken. In experimental group, microscopic examination of nasal respiratory mucosa revealed that degenerative changes in epithelium were observed in sections of propineb-treated group. There were also leukocyte infiltration and vascular dilatation detected in the connective tissue.We detected CD34-immunoreactive mononuclear...

In ovo administration of human recombinant leptin shows dose dependent angiogenic effect on chicken chorioallantoic membrane
Provedor de dados: Biological Research
Autores: Manjunathan,Reji; Ragunathan,Malathi.
BACKGROUND: Leptin, the cytokine produced by white adipose tissue is known to regulate food energy homeostasis through its hypothalamic receptor. In vitro studies have demonstrated that leptin plays a major role in angiogenesis through binding to the receptor Ob-R present on ECs by stimulating and initiating new capillary like structures from ECs. Various in vivo studies indicate that leptin has diverse effect on angiogenesis. A few reports have showed that leptin exerts pro angiogenic effects while some suggested that it has antiangiogenic potential. It is theoretically highly important to understand the effect of leptin on angiogenesis to use as a therapeutic molecule in various angiogenesis related pathological conditions. Chicken chorio allantoic...

Quantificação de células CD34+ do sangue do cordão umbilical de cães
Provedor de dados: Ciência Rural
Autores: Nakage,Ana Paula Massae; Santana,Aureo Evangelista; Cápua,Maria Luisa Buffo de; Godoy,Aline Vieira.
As células-tronco promovem a reconstituição hematopoética e de outros tecidos, estando presentes no embrião, no sangue periférico, na medula óssea e no sangue do cordão umbilical (SCU). Os modelos experimentais de células-tronco do sangue periférico e da medula óssea em cães têm propiciado informações relevantes para transplantes de células-tronco em humanos. Entretanto, não existe estudo sobre as células-tronco no SCU canino no Brasil. O objetivo deste ensaio foi quantificar as células nucleadas e as células-tronco CD34+ no SCU de cães para propostas de reconstituição hematológica. No presente protocolo experimental, a coleta de SCU de 40 cães neonatos foi realizada para contagem das células nucleadas no contador automático de células sangüíneas e...
