Squamous cell carcinoma of the tongue is one of the most common head and neck cancer. Treatment in the early stages is still controversial. This study aims to correlate the apoptosis rate of primary tongue cancer with cervical node metastasis, found in the histopathological studies of specimens obtained from neck dissections or during clinical follow-up. Twenty patients, 65% males, mean age 64.5 years, without clinical evidence of cervical metastasis was included. Eighty-five percent were smokers and 40% were alcohol abusers. Mann-Whitney test was used for statistical analysis (p=0.05). Five patients with clinically occult cervical metastases had metastasis in the histopathological specimens (25%) occult metastasis. The mean apoptosis rate in patients without cervical metastasis was 9.43%. Twenty-five percent of the patients had occult cervical metastasis. High apoptosis rate in tongue cancer, even in the absence of palpable neck nodes, correlates with the presence of occult metastasis. 相似文献

The kinetics of the anodic dissolution of metallic uranium in 1, 2, 3, and 4 mol.l-1 HNO3 solutions at 30 °C were studied by potentiostatic polarization. The dissolved uranium was determined by polarography and the anodic dissolution rates by the initial rate method. It was observed that the dissolution rate increases with the applied potential, but is independent of the HNO3 concentration, because it is a zero order reaction. A mechanism for the anodic reaction was proposed based on the adsorption theory. 相似文献

The invariant integration method for Chern-Simons theory defined on compact hyperbolic spaces of the form Γℍ3 is verified in the semiclassical approximation. The semiclassical limit for the partition function is calculated. The contribution
to the sum over topologies in three-dimensional quantum gravity is briefly discussed.

Background
Considerable research has been directed towards the roles of metal ions in nutrition with metal ion toxicity attracting particular attention. The aim of this study is to measure the levels of metal ions found in selected beverages (red wine, stout and apple juice) and to determine their potential detrimental effects via calculation of the Target Hazard Quotients (THQ) for 250 mL daily consumption. 相似文献7.
