Rate of apoptosis in feline mammary tumors is not predictive of postsurgical survival.

Invasion, cell proliferation and apoptosis are important biological features of neoplasia, bearing prognostic importance. Histological stage, mitotic index, and apoptotic index have been assessed in 33 feline malignant mammary tumors. Histological stage (P < 0.01) and mitotic index (P < 0.001) had a significant association with prognosis in univariate analysis. Apoptotic index did not correlate with survival (P = 0.44), and histological stage (P = 0.48) did not correlate with mitotic index (P = 0.39). In feline malignant mammary tumors the apoptotic index seems unable to predict survival and lacks any correlation with proliferation assessed as mitotic index. A possible explanation for the lack of correlation between apoptotic index and survival may be due to the rapid acquisition of pathways of apoptosis resistance in feline mammary tumors or to rapid hormone receptors loss.  相似文献   

Prognostic value of histologic stage and proliferative activity in canine malignant mammary tumors.     

Giuseppe Sarli  Rosario Preziosi  Cinzia Benazzi  Gastone Castellani  Paolo Stefano Marcato 《Journal of veterinary diagnostic investigation》2002,14(1):25-34

The aim of this study was to investigate the correlation between the histologic invasiveness (histologic stage) and various cell proliferation activity assays (quantity of argyrophil proteins associated with nucleolar organizer regions [AgNORs], mitotic activity, MIB1 [Ki67] immunohistochemical detection) for predicting the biologic behavior of malignant canine mammary tumors. Sixty specimens from malignant canine mammary tumors with no distant metastases (M0) at surgery were selected, and follow-up data were collected over a 2-year period. The histologic invasiveness was graded by histologic stage (stage 0 = tumors without stromal invasion; stage I = tumors with stromal invasion; stage II = tumors with neoplastic emboli in vessels), and the proliferative indices were expressed as MIB1 index (the percentage of nuclear area immunohistochemically stained by MIB1 antibody), mitotic index (the number of mitoses per 1,000 neoplastic cells), and AgNOR index (the ratio between mean AgNOR area of tumor cells and the mean AgNOR area of fibroblasts/lymphocytes). The measures of proliferative activity were compared among groups with different histologic stages, and the influence of different prognostic variables (histologic stage, AgNOR index, mitotic index, MIB1 index) on survival time was evaluated. A significant difference in the proliferation patterns was recorded between the different histologic stages for the mitotic index (P = 0.0006) and MIB1 index (0.0013). Among the different parameters considered, histologic stage (P < 0.05), AgNOR index (P = 0.0291), and MIB1 index (P = 0.014) revealed a significant association with prognosis in univariate analysis. AgNOR index for 1-year survival and histologic stage for 2-year survival were the most significant parameters influencing survival, as determined by multiple nonlinear logistic regression.  相似文献   

Fatal septicaemia caused by Aeromonas hydrophila in a patient with cirrhosis     

Karel Krovacek  Marco Conte  Patrizia Galderisi  Giuseppe Morelli  Attilio Postiglione  Stefano Dumontet 《Comparative immunology, microbiology and infectious diseases》1993,16(4):267-272

In this case report from Italy we describe a fatal infection caused by A. hydrophila in a 39 yr old cirrhotic patient. This pathogen was isolated as a pure single culture from the patient's blood sample. The patient died on the second day of hospitalization from overwhelming sepsis. The A. hydrophila isolate was tested for different potential virulence properties, such as invasiveness, adherence, exotoxins production, presence of fimbriae and for the patterns of resistance to a variety of antimicrobial agents. Although, the Aeromonas species are infrequently reported as a cause of human infections, the present case study confirms the capability of these pathogens to induce serious human infections.  相似文献   

Somatic embryo,adventitious root and shoot regeneration in in vitro grown quince leaves as influenced by treatments of different length with growth regulators     

Claudio D’Onofrio  Stefano Morini 《Scientia Horticulturae》2006

The purpose of this work was to acquire more information on the capacity of in vitro grown quince (Cydonia oblonga Mill.) leaves to simultaneously regenerate somatic embryos, adventitious roots and shoots, and to evaluate the variations induced on regeneration response by treatments of different length with growth regulators. After 2 days of liquid treatment with 2,4-dichlorophenoxyacetic acid, the leaves were cultured for 0, 3, 6, 9, 12, 15, 18 and 21 days on gelled growth medium containing the basal components of Murashige and Skoog and kinetin (Kin) 4.5 μM + naphthaleneacetic acid (NAA) 0.5 μM. At the end of each treatment period, the leaves were cultured on a transfer medium in the absence or in the presence of a growth regulator combination represented by N⁶-benzylaminopurine (BA) 2.66 μM + gibberellic acid 0.58 μM + indole-3-butyric acid 0.3 μM. The culture period for all the treatments was fixed to 52 days.  相似文献   

Atipamezole in the management of detomidine overdose in a pony     

Di Concetto S  Michael Archer R  Sigurdsson SF  Clarke K 《Veterinary anaesthesia and analgesia》2007,34(1):67-69

OBSERVATIONS: A pony undergoing elective castration accidentally received an overdose of IV detomidine (200 microg kg(-1)) before anaesthesia was induced with ketamine and midazolam. A further 100 microg kg(-1) IV dose of detomidine was administered during anaesthesia. The mistake was recognized only when the animal failed to recover from anaesthesia in the expected time. The overdose (300 microg kg(-1) in total) was treated successfully with atipamezole, initially given IV and subsequently IM and titrated to effect to a total dose of 1100 microg kg(-1). The pony regained the standing position. A further injection of atipamezole (76 microg kg(-1) IM) was given 5 hours later to counteract slight signs of re-sedation. CONCLUSIONS: Atipamezole proved an effective antagonist for detomidine in a pony at an initial dose 3.65 x and a final total dose 3.9 x greater than the alpha2 agonist.  相似文献

Solomonsterol A,a Marine Pregnane-X-Receptor Agonist,Attenuates Inflammation and Immune Dysfunction in a Mouse Model of Arthritis     

Andrea Mencarelli  Claudio D’Amore  Barbara Renga  Sabrina Cipriani  Adriana Carino  Valentina Sepe  Elisa Perissutti  Maria Valeria D’Auria  Angela Zampella  Eleonora Distrutti  Stefano Fiorucci 《Marine drugs》2014,12(1):36-53

In the present study we provide evidence that solomonsterol A, a selective pregnane X receptor (PXR) agonist isolated from the marine sponge Theonella swinhoei, exerts anti-inflammatory activity and attenuates systemic inflammation and immune dysfunction in a mouse model of rheumatoid arthritis. Solomonsterol A was effective in protecting against the development of arthritis induced by injecting transgenic mice harboring a humanized PXR, with anti-collagen antibodies (CAIA) with beneficial effects on joint histopathology and local inflammatory response reducing the expression of inflammatory markers (TNFα, IFNγ and IL-17 and chemokines MIP1α and RANTES) in draining lymph nodes. Solomonsterol A rescued mice from systemic inflammation were assessed by measuring arthritis score, CRP and cytokines in the blood. In summary, the present study provides a molecular basis for the regulation of systemic local and systemic immunity by PXR agonists.  相似文献
