Experimental ocular siderosis was induced in fourteen albino rabbits by the insertion of iron fragments through the scleral incision made at equatorial region. ERGs were recorded up to 30 days after the insertion of iron, both in scotopic and photopic conditions. Light stimulus used was electronic photoflash of 2 msec duration. The changes in the scotopic b-wave were classified into 3 types. The first type (4 eyes) showed gradual decrease finally attaining 54.6% of the original amplitude. The second type (3 eyes) showed supernormal b-wave during whole period of study, the increase reached 43.0% after 30 days. In the third type (6 eyes) the b-potential remained almost stationary. The scotopic a-wave changed in a similar way as the b-wave. Sometimes negative (-) type ERGs were recorded, especially during the falling stage of the b-potential. The photopic a- and b-waves changed almost parallel to the scotopic components. By slitlamp biomicroscopy and ophthalmoscopy, fibrous connective tissue proliferated around the iron fragments, never extending deep into the vitreous body. Fundi were well visible except the insertion site. Histological section revealed moderate scar tissue formation around the insertion site of iron, and mild visual cell and ganglion cell destructions.

Vitreous hemorrhages of white rabbit eyes were obtained by the following three methods and their ultrasonographies were checked several times for four weeks. 1 st group: fresh human blood was injected into the vitreous cavity through the sclera, 2 nd group: oxalated human blood was injected into the vitreous cavity in the same way, 3 rd group: a 26 gauge needle was inserted into the vitreous cavity and retinal vessels were mechanically ruptured to cause vitreous hemorrhage. Ultrasonography of the above groups revealed no definite differences between groups, but a high echo from the vitreous hemorrhages in initial stage changed to several low echoes in later stage. This fact was well matched with funduscopic observation for gradual absorption of the vitreous hemorrhage.

Ultrasonography is most commonly utillized diagnostic tool in obstetric and gynecology for the evaluation ofpatient with a pelvic mass or pregancy. For it is characterized by no radiation hazard, noninvasive examinationand high diagnoastic accuracy. Also it affords an accurate assessment of the presence, size, location and internalconsistency of a pelvic mass. The recent availability and improved resolution of realtime scanning have afforded amore flexible and complete approach to evaluation of normal and abnormal structures in the pelvis. We analyzedultrasonographic findings in 154 pathologically proven cases of pelvic mass examined at Korea General hospitalfrom Jan. 1983 to Apr. 1984. The results were as follows; 1. The age distribution was from 12 years to 66 yearsand the majority of patients were between the ages of 21 and 50 yeasrs (91.4%). 2. The incidence of pelvic masswas 27.9% in uterine leiomyoma, 22.7% in ovarian cyst, 13.0% in addenomyosis and 8.4% in serous cystadenoma. 3. Mild to moderately echogenic nodular uterine enlargement with some cystic change(81.5%) of leiomyoma and multiplesmall vesicular pattern of intrauterine contents with uterine enlargement of Homole were the most common ultrasonographic findings. The location and type of leiomyoma were most common in the fundus and body (95.3%), and intramural myoma(53.5%). The most frequent finding of ovarian teratoma was cystic mass with echogenic focus(41.7%) but the echogenic appearance of the lesions was extremely variable. The ultrasonographic findings ofectopic pregnancy were cystic or complelx adnexal mass(80.0%), with or without fluid in cul-de-sac and deviationof uterus by adenxal mass. 4. Accuracy of ultrasonography in detemining the overall correct diagnosis of thepelvic masses compared with proven diagnosis was approximately 61.7%. The diagnostic accuracy was 90.7% inluterine leiomyoma, 100% in H-mole nad 80.0% in ectopic pregnancy.

One hundred forty eight complications in 135 cases of long bone fractures experienced during the period from May 1971 to December 1979, at the Chosun University Hospital and analysed its retrospectively. The results were obtained as follows. 1. The order of incidence of complications were as follows; infection (39.8%), delayed union(23.6%). malunion (13.5%), ankylosis of joint (12.2%). nonunion (8.1%) and peripheral nerve injury (2. 8%). 2. Of all 127 patients, 97 patients were male and 30 patients were female, and 72 patients (56.7%) were cauesd by traffic accidents. The sex ratio between male and female was 3.2: l. 3. The major complications were frequently associated with other fractures and dislocations, brain injuries. 4. Those of open, comminuted fracture and delayed transfer cases to the Orthopedic Surgeon were predisposing factors to development of the severe complication.
