T1 is a T-cell potentiating factor.

胸腺素α1（thymosin 1，Tα1）是由28个氨基酸组成的酸性多肽，等电点4.2，相对分子量3108，其氨基酸序列为：N-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-C[1，2]。Tα1具有多种免疫活性，可以促进T淋巴细胞的成熟和分化，促进成熟的T细胞、自然杀伤细胞分泌各种细胞因子如IL-2、INF-α等，同时也促使高亲和力白介素-2受体的生成[3-10]。

The method is as follows that the two ends of a nanometer are fixed on two pivots and an axial micro-pulling force T is applied on the nanometer; an electrode is arranged on the middle part of the side of the nanometer and an alternate voltage is applied on the electrode to motivate the nanometer to generate resonance, and therefore, the natural frequency f of the nanometer is measured and acquired; according to the material characteristics and the geometry characteristics of the nanometer as well as the boundary condition of the nanometer material, the relation between the natural frequency and the axial pulling force of the nanometer, namely the f-t curves of the nanometer, can be calculated by a vibration equation; according to the measured natural frequency f, the size of the micro-pulling force T can be acquired.

该方法将一根纳米材料的两端固定在两个支点上，给纳米材料施加一个轴向的微小拉力T；在纳米材料的侧面，位于该纳米材料的中部放置一个电极，在电极上施加一个交变的电压激励纳米材料使其发生共振，测得纳米材料的固有频率f；根据纳米材料的材料特性和几何特征以及纳米材料的边界条件，由振动方程计算出该纳米材料的固有频率与所受的轴向拉力的关系，即纳米材料的f-T曲线；根据上述测得的固有频率f，得到微小拉力T的大小。

There was significant difference in T lymphocyte proliferation between the TF treatment groups and the control groups (p＜0.01), and between TF from black-bone silky fowl and other treatment groups (p＜0.01). Significant difference was detected between TF from black-bone silky fowl and homogenous Cherry Valley duck (p＜0.01). The effect on T lymphocyte proliferation in vivo was markedly enhanced when taking oral TF in 24 h, and significant difference remained between the treatment groups and the control groups in 240 h.
