Abstract
The glutaminase activity in rat and guinea pig retina is twice as high in photoreceptor inner segments as in any other layer. Since the inner segments are involved in non-transmitter-related metabolic functions, it is suggested that glutaminase should not necessarily be taken to imply glutamatergic neurotransmission until the function of the high activity in regions such as the inner segments is better understood.
摘要
大鼠和豚鼠视网膜中的谷氨酰胺酶活性在光感受器内节中的水平是其他任何层的两倍。由于内节参与与神经递质无关的代谢功能，因此有人提出，在更好地了解内节等区域高活性的功能之前，谷氨酰胺酶活性高不一定意味着存在谷氨酸能神经传递。
