Histological sections of the pharyngeal tonsil (PhT) have been investigated in 55 corpses of persons of both sex and various age, that had no disease connected with lesions of the PhT by the time of their death. The aim of the work is to determine relative areas of each structural element of the PhT in comparison to the whole section area taken as 100%. The PhT lymphoid tissue reached its maximal relative development at the first childhood. Then the lymphoid tissue area in the PhT histological sections decreases gradually, making already in the second mature age one half of the tonsil section area, and in the elderly age--nearly one-fourth. The decrease of the relative lymphoid tissue area takes place at the expense of decreasing area of the lymphoid nodules. The relative area of the connective stroma increases inversely to the relative decrease of the lymphoid tissue area parameters. The germinative centers in the lymphoid nodules are absent in newborns and old persons. The greatest value of the relative area of the germinative centers falls to the early infancy. The lymphoid nodules with the germinative centers, according to their relative area during all age periods, besides the newborn period, the second mature, elderly and old age periods, essentially exceed the area, that occupy the nodules without the germinative centers on the PhT sections.
对55具不同年龄和性别的尸体的咽扁桃体（PhT）组织切片进行了研究，这些人在死亡时没有与PhT病变相关的疾病。这项工作的目的是确定PhT每个结构元件的相对面积与作为100%的整个切片面积相比的情况。PhT淋巴组织在儿童早期达到其最大相对发育程度。然后，PhT组织切片中的淋巴组织面积逐渐减小，在成年中期已占扁桃体切片面积的一半，而在老年期则接近四分之一。相对淋巴组织面积的减少是以淋巴小结面积的减少为代价的。结缔组织基质的相对面积与淋巴组织面积参数的相对减少成反比。新生儿和老年人的淋巴小结中没有生发中心。生发中心相对面积的最大值出现在婴儿早期。除新生儿期、成年中期、老年期和高龄期外，在所有年龄段，有生发中心的淋巴小结，根据其相对面积，基本上超过了PhT切片上无生发中心的小结所占的面积。
