The fatter mice in Gewirtz's study had been bred to lack a protein known as toll-like receptor 5 (TLR5), which most intestinal cells sprout on their surface. Its job is to recognize and bind to the whiplike flagella that bacteria use to move around. TLR5 acts as a traffic cop for controlling the mass of pathogens living in the intestine; without it, the normally harmless gut bacteria tend to overflourish and expand in number.

Gewirtz 实验中的胖小鼠普遍缺乏一种被称之为 toll 样受体5 (TLR5)的蛋白，这种蛋白是肠上皮细胞表面分泌的， TLR5的作用是识别并结合在肠道细菌的运动器官鞭毛上，在对大多数肠道病原体的控制中， TLR5扮演着交通警察的角色，没有它，一般无害的肠道菌就会异常活跃并且大量繁殖。

Histologically, there were 2 cases of MC, 7 of MLMP (7 cases; 3 of them with intraepithelial carcinoma and 1 with microinvasion), and 9 of MCas (9 cases, 5 of them associated with MLMP and 1 associated with MC). Three of the MCas had areas of anaplastic or sarcomatoid carcinoma whereas 1 had an associated sarcoma.

The secrection of the pyramidal secretory cells is ejected into the spermathecal cavity through secretory canals. The preliminary histochemical stainings shows that the secretion is a kind of glycoprotein and probably plays an important role in storing sperms.

Results The mortality rate of mice in 80 mg/kg, day cyclophosphamide group was 16.7%, and T level [ at 30th day :( 1.38 ± 0.31 );45th day:( 1.15 ± 0.26 ) ] and T/LH ratio [ at 30th day:(0.163 ± 0.014); 45th day:(0.127 ± 0.023 ) ] were significantly decreased (all P＜0.05) at 30th day after induction;The concentration of MDA [at 15th day:(2.70 ± 0.41);30th day:(2.710.36);45th day:(2.67 ±0.43) ] was maintained at a high level (all P＜0.05) during the 45 days ; Number of Leydig's cells [ at 15th day:(9.65 ± 0.75 ); 30th day:( 14.05 ± 0.67 ); 45th day:(8.49 ± 072)] and layers of spermatogenetic epithelia [ at 15th day:(4.75 ± 0.82);30th day:(3.60 ± 0.49);45th day:(3.74 ± 0.43 ) ] were significantly decreased ( all P ＜ 0.01 ) and stabilized in a low level. The induced model was stable and the mortality rate was acceptable. In the 60 mg/kg, day cyelophosphamide group, the T level and T/LH ratio had no significant change (P ＞ 0.05 ), and the concentration of MDA ,number of Leydig' s cell and layers of spermatogenetic epithelia recovered at 30th day after induction. The induced model was unstable.

结果 剂量每日为80 mg/kg体重小鼠成模后死亡率为16.7%，血清T[30 d：(1.38±0.31)；45 d：(1.15±0.26)]及T/LH比值[30 d：(0.163±0.014)；45 d：(0.127±0.023)]于诱导后第30天出现显著下降(P均＜0.05)，而诱导后睾丸组织内MDA含量[15 d：(2.70±0.41)；30 d(2.71±0.36)；45 d：(2.67±0.43)]维持高水平(P均＜0.05)，生精上皮层次[15 d：(4.75±0.82)；30 d：(3.60±0.49)；45 d：(3.74±0.43)]和间质细胞[15 d：(9.65±0.75)；30 d：(14.05±0.67)；45 d：(8.49±0.72)]均显著减少(P均＜0.01)并稳定于低水平，模型稳定，死亡率适当；每日60mg/kg体重组小鼠血清T及T/LH比值于不同时段并未出现明显变化(P＞0.05)，且睾丸组织内MDA含量、生精上皮层次和间质细胞计数在30 d后有所恢复，模型不稳定；每日100 rag/ks体重组死亡率为30.0%，死亡率过高。

Taking all together, we proposed a energy metabolism model in gill epithelial cells during SW acclimation: The tricarboxylic acid cycle in MR cells is stimulated to produce enormous amount of energy for maintaining homeostasis and ion regulation at the 1st h after transfer to SW.

藉由上述结果，我们认为在鱼类适应不同盐度过程中，其鳃上皮细胞能量代谢的机制如下：当鱼类转移到海水后1st h时，其鳃上的MR cells会进入柠檬酸循环以产生大量的能量给MR cells。
