Methods the improvements of the operation included ; a supertemporal conjunctival flap 180 with its base at the fornix , the puncture points were located at 8 and 2 o ' clock ( right eye ) or 10 and 4 o ' clock ( left eye ) , the straight needle and shovel needle with prolene suture were conducted into the eye via two different side of corneal incision and out of the eye under the scleral flap at 8 and 2 o ' clock ( right eye ) 方法术式改进包括：颞上方180 、以穹隆为基底的大结膜瓣；穿刺点选择8点及2点位（右眼）或10及4点位（左眼） ；用聚丙烯缝线所带直针及铲针，从角膜切口两端进入眼内，由8点及2点位巩膜瓣下穿刺出针。

2 . the test of space learning and memory task of young sd rats administrated by ktm ( i . p . ) in the morris water maze : the rats were divided into six groups as following : the control group , the ktm group , the marginal division ( mrd ) group , the fimbria / fornix ( ff ) group , the ktm + mrd group and the ktm + ff group 试验结果: ( l )腹腔注射ktm组与对照组比较，学习记忆能力明显下降，有显著的统计学差异( p < 0 . 0匀; (劝mrd毁损组与ff离断组与对照组比较，学习记忆能力下降，有显著的统计学差异( p < a仍) ;但加介d毁损组与ff离断组组间比较，无显著的统计学差异( p二0 . 46 ) 。

The advantages of this modified technique can be stated as follows : ( 1 ) healing was apparently faster . ( 2 ) postoperative pain was minimal . ( 3 ) depth of vestibular fornix was increased markedly . ( 4 ) frenum and muscle attachment pull almost completely relieved . ( 5 ) there was less possibility of exposing a dehiscence or creating bone 1055 on adjacent teeth . ( 6 ) a function - ally adequate zone of attached gingiva was numerically increased 本改良法的优点，可归纳以下几点: ( 1 )手术伤口愈合快( 2 )术后疼痛小( 3 )口腔前庭宽度明显增加( 4 )颊系常及肌肉的拉扯，几乎获得完全改善( 5 )不易引起手术区周围齿槽骨的裂开缺损( 6 )固著性齿龈宽度的增加至为明显。
