牛蛙

It was firstly demonstrated that the frog mast cells contain tryptase in their cytoplasm and an excellent cross-reaction of the antibody AA1 with frog mast cell tryptase was obtained from the Boun's fluid fixed frog tissues.

首次在Bouin氏液固定的牛蛙组织中证实了牛蛙肥大细胞胞浆中类胰蛋白酶的存在，且单克隆抗体AA1与牛蛙肥大细胞中的类胰蛋白酶可获得良好的交叉反应。

A small bullfrog that doesn't watch its step can easily become food for a bigger frog.

行走不注意的小牛蛙很容易成为体型较大的牛蛙的食物。

He still thinks he became tired one day, arose psychedelic, but become him to be caught one, wow, it is 7 legs really, frighten at that time was in on the ground, this strange bullfrog was not being frightened however, continue retroflexion in its sky 360 degrees tall difficulty movement, immediately this bullfrog became a central issue, the employee in inn was surrounded come over.

他还以为自己累了一天，产生了幻觉，可是当他抓出来一数，哇，真的是七条腿，当时就吓掉在了地上，这个奇怪的牛蛙却没吓着，继续它的空中翻转360度高难度动作，顿时这只牛蛙成了焦点，店里员工都围了过来。

Analyses of stomach contents showed that, for adult bullfrogs, the most important prey items overall were Decapoda, Coleoptera, Odonata, Mesogastropoda, Raniformes, and Cypriniformes; while for juvenile bullfrogs, they were Decapoda, Coleoptera, Cypriniformes, Odonata, Orthoptera, Hymenoptera, Lepidoptera larvae, Mesogastropoda, and Raniformes. Moreover, prey size and diet volume increased with the body size of both adult and juvenile bullfrogs. The diet composition of primary preys of bullfrogs was significantly different among different islands.

食性分析结果表明：(1)按食物体积计算，成年牛蛙以十足目、鞘翅目、蜻蜓目、中腹足目、蛙形目和鲤形目为主要食物，亚成体牛蛙以十足目、鞘翅目、鲤形目、蜻蜓目、直翅目、膜翅目、鳞翅目幼虫、中腹足目和蛙形目为主要食物；成体和亚成体牛蛙胃中食物的平均大小均随其体长增加而增大；(2)不同岛屿上的牛蛙在主要食物类型构成上存在差异。

The baritone call of the bullfrog is so deep and resonant, it resembles the mooing of a cow, hence its name.

牛蛙的叫声很深沉并能产生回响，这声音类似于母牛的哞哞声，这就是牛蛙名字的来源。

In conclusion, like human mast cells, bullfrog mast cells also contain the special enzyme, tryptase and it was likely that bullfrog can be used as an ideal experimental animal for the study of mast cell biology.

研究证实，与人类肥大细胞相似的是牛蛙肥大细胞也含有这种特有的类胰蛋白酶，牛蛙有可能是用作肥大细胞生物学研究的理想实验动物。

Cuisine: Bullfog here is absolutely fresh, you may select several jin (1/2 kg) of bullfog to in person, the chief will kill them and boil with the red peppertogether. And he will put bean sprouts to the pot. The meat of these bullfog is extremely tender, and you can taste the fragrant spicy flavour with slight sweet taste of the meat, especially when the bullfog is boiled in the pot for a long time.

菜品特写：在这儿吃牛蛙是绝对新鲜的，你点几斤就现场剖几斤，去皮洗净之后和一种特制的红辣椒一起烹制，再用豆芽菜打底上干锅，牛蛙肉非常嫩，香辣中还带有丝丝甜味，尤其在干锅中久煮之后入味更重，余香更长。

A total of 391 bullfrogs were measured during the study period, including 113 adults and 278 juveniles.

共采集到变态后的牛蛙391只，包括牛蛙成体113只和亚成体278只。

We investigated bullfrogs in Zhoushan Archipelago and Ningbo area in the east of Zhejiang Province, China.

我们于 2 0 0 3年 9- 11月调查了浙江省东部 5区 3县的牛蛙种群，发现在岱山、秀山、六横及佛渡岛上有牛蛙分布，共捕获 2 3只牛蛙，包括 4只成年个体，18个亚成体和 1只蝌蚪。

Any of several large, heavy-bodied frogs, chiefly of the genus ''.

牛蛙一种大的，体重的蛙，蛤蟆属，尤指牛蛙原产于北美，有很具特色的低沉的，洪亮的叫声

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
