After HRP application, HRP labelled cells were distributed in the nucleus of trapezoid body , lateroventral periolivary nucleus , retrotrapezoid nucleus , lateral paragigantocellular nucleus and lateral reticular nucleus . The findings demonstrated the existence of neural structural relations between the chemosensitve areas and the Tz, LVPO, NRT, LPGi and LRt, and revealed that these nuclei might participate in the mechanism of central chemical regulation on respiration.

观察到用浸有HRP的滤纸局部敷贴于延髓腹外侧表面化学感受区后，在延髓斜方体核、外周橄榄腹外侧核、斜方体后核、巨细胞旁外侧核和外侧网状核等核团找到HRP标记的细胞，表明上述延髓内部核团与腹外侧表面化学感受区之间存在神经结构联系，提示延髓腹外侧表面化学感受区对H〓等物质的化学感受机制可能与上述核团神经元伸向该区的突起有关。

Despite the poor response rates in the chemotherapy-alone group, Dr. Burstein believes that metronomic chemotherapy combined with bevacizumab should be investigated further, given the tolerability of the agents and the preclinical rationale for efficacy. When asked why cyclophosphamide and methotrexate were selected for metronomic chemotherapy, he observed that many patients in this setting are already somewhat chemotherapy-resistant.

尽管只接受化学疗法的病患反应率很低，Burstein医师相信节律性化学疗法加上bevacizumab应该进一步研究，因为该药物的耐受性良好，而且临床前实验认为是有效的；当被问到为什么选择cyclophosphamide与methotrexate作为节律性化学疗法的药物，他观察发现，许多病患在这个时候已经对许多化学疗法产生抗药性。

In order to provide an overall understanding on the basic theory and previous researches of wood chemical rheology, the author discusses some respects on the basis of the common knowledge of deformation and flow, which served as the foundation of wood chemical rheology. These respects include the results by Stein and Tobolsky, such as the correlation between the change of polymolecular structure and stress relaxation, the classification of physical rheology and chemical rheology, the difference between the research on wood chemical rheology and other methods, as well as a kind of non\|continuous method to measure stress relaxation proposed by Tobolsky \%et al.
