A study was performed on enzyme activities, myosin light chain pattern and histochemical composition of extraocular muscles (EOM) of rabbit. The results were compared with those from slow-twitch soleus and fast-twitch psoas limb muscles. EOM were found to contain myosin light chains of both slow and fast skeletal muscles, with the latter being predominant. The activities of the enzymes regulating glycolysis and lactic acid fermentation were found to lie between those measured in soleus and psoas muscles, whereas the activities of the enzymes involved in oxidative metabolism were found to be very similar or even higher than in soleus muscle. All five isozymes of lactate dehydrogenase (LDH 1-5) were found in EOM. The predominant species was LDH-3 illustrating that this pattern is uncharacteristic of either slow soleus or fast psoas muscles. The complex structural and functional characteristics of EOM might result from the observed heterogeneity of fibres.
对兔眼外肌（EOM）的酶活性、肌球蛋白轻链模式和组织化学组成进行了一项研究。将结果与慢肌比目鱼肌和快肌腰大肌的结果进行了比较。发现眼外肌含有慢、快骨骼肌的肌球蛋白轻链，其中后者占主导。发现调节糖酵解和乳酸发酵的酶活性介于比目鱼肌和腰大肌中测得的活性之间，而参与氧化代谢的酶活性与比目鱼肌非常相似，甚至更高。在眼外肌中发现了乳酸脱氢酶的所有五种同工酶（LDH 1-5）。主要类型是LDH-3，表明这种模式既不是慢肌比目鱼肌也不是快肌腰大肌所特有的。眼外肌复杂的结构和功能特征可能源于观察到的纤维异质性。
