31 cases of the trochanteric fractures were treated at the Department of Orthopedic Surgery, Chosun University Hospital, from Jan. 1975 to Dec. 1978 and the following results were obtained. 1. The sex ratio was 3:2 (male to female). 18 cases were in man, with the peak age at the 4th decade and 5th decade and 13 cases were in woman over the 6th decade. 2. The most common causes of the trochanteric fractures were traffic accident or fall in man and slipping in woman. 3. The features of the trochanteric fractures were mostly unstable type (60%) and 16 cases in the right hip (52%) and 15 cases in the left hip (48%). 4. Dimon-Hughston method and Wayne-Country method were used to the unstable fractures and anatomical reduction to the stable fracture was maintained by inserting the S-P nail, Jewett nail and Mclaughlin nail. 5. Post-operative cast immobilization was applled until clinical union was oftained on the fracture site and early weight bearlng was carried out for the acceleration of the bony union. 6. Complications were found in 50% of the group treated by conservative method, while it occurred in 21.7% of the group treated surgically.

The cases of 128 humeral fractures were evaluated at the Department of Orthopedic Surgery, Chosun University Hospital, during the six year period from January 1974 to December 1979 and the following results were obtained. 1. The high incidence of the humeral fracture was found under the age of 30 years and the sex ratio between the male and female was 3.6:1. 2. The most common causes of injuries were fallen down on the ground (36.7%) and the nexts were traffic accidents (34.4%). 3. Among the 128 cases of fractures, humeral shaft fractures were 33 cases (32%) under the age of 40 years and 47 cases (67.1%) of supracondylar fractures under the age of 20 years and 6 cases (54.5%) of neck fractures over the age of 60 years were noted. 4. The shapes of humeral fractures found out transverse fracture in 31 cases (65.9%) and the short oblique or spiral fracture in 35 cases (71.4%). 13 cases were combined with the open would to the fracture site (10.2%). 5. In the Correlation between the age and the union rate, sound union was more rapid under the age of 20 years than the aged person. Delayed unions were revealed 5 cases in transverse fractures, 2 cases in spiral fractures and 2 cases of nonunions were experienced on both segmental and transverse fracture of the shaft (1.6%). 6. The radial nerve paralysis revealed 5 cases (10%) at the shaft fracture and 2 cases (4.3%) Volkmanns ischemic contracture, 2 cases (4.3%) of cubitus varus, 2 cases (4.3%) of cubitus valgus were experienced on the complicution in there 47 cases of supracondylar fractures.

Bacterial infection has been implicated in premature labor in human. But it is impossible to undergo human study of bacteria-induced preterm delivery. If we carry out animal experiment which simulate human preterm delivery induced by bacteria, studies for mechanism, diagnosis, and treatment of preterm delivery will be progressed rapidly. To elucidate mechanisms and potential intervention strategies in preterm pregnancy loss, we observed bacteria-induced preterm labor and the protecting effect of administration of antibiotics with hysteroscopy-guided intracervical inoculation of Escherichia coli. Sterile saline solution(group I, n=5) or 2x10(7)cfu (colony-forming units) of E. coli bilaterally in the cervix of pregnant New Zealand White rabbits on day 20 or 21(70% of gestation) by hysteroscopy was inoculated and rabbits were assinged to ampicillin-sulbactam therapy beginning at 0hr(group II, n=4), 2 hr(group III, n=4), 4 hr(group IV, n=2), and 16 hr(group V, n=2) after inoculation with E. coli, or to no antibiotic therapy(group VI, n=3). Unasyn(ampicillin-sulbactam) was used and its daily dosage was 100 mg/kg/day. The occurrence of vaginal bleeding or preterm birth was observed every two hours. If one rabbit fetus was found to be delivered, exploratory laparotomy was done. Amniotic fluid culture on each sac, decidual culture on each uterine cavity, and pathologic examinations on each placenta were done. The results of experiments are as follows. In control group(0.2cc sterile saline inoculation only), there was no preterm labor and no bacterial growth in culture. In all three rabbits in group VI, preterm delivery occurred and the culture results were all positive in maternal blood, decidua, and amniotic sacs. Preterm delivery also occurred in group V, but results of maternal blood culture were all negative. Increased trend in the occurrence of preterm delivery was statistically significant in the order(p < 0.05) : group I(0/5), group II(0/4), group III(0/4), group IV(0/2), group V(2/2), and group VI(3/3). Pregnancy outcomes on the basis of the number of living fetus, dead fetus, and macerated fetus, have significant trend in the above order. Amniotic fluid culture results also had significant relationship(p < 0.05) : group I(0.20), group II(20/26), group III(18/30), group IV(10/11), and group VI(7/7). In group V, amniotic fluid fail to be obtained due to severe oligohydramnios. Decidual culture results also had an increased trend; group I(0/32), group II(21/29), group III(20/30), gorup IV(16/16), gorup V(11/11), and group VI(25/25). It is statistically significant(p < 0.05) Incidence of histologic chorioamnionitis was also significantly increased from group I to VI. These results indicate that E. coli inoculation has induced preterm delivery and antibiotic therapy has somewhat prevented preterm birth, amniotic fluid infection, decidual infection, and histologic chorioamnionits. Antibiotic effects were attenuated in cases of delayed antibiotic administration.
