In recent years, with increased number and higher speed of the automobiles, the incidence of the so-called whiplash injury has been increasing. The author had studied the clinical symptoms and signs, roentgenographic findings, associated injuries and treatment of the sixty four patients who had admitted to the Yonsei Medical Center under the diagnosis of the whiplash injury excluding the patients who had sustained an associated injuries those may cause neurologic symptoms and signs during the period of eight years from January, 1972 to December, 1979. and sumnerized the results as followings. 1. Among the sixty four patients, thirty one (48.4%) were male and thirty three (51.6%) were female. The most prevalent age were third and fourth decades (62.5%). 2. The causes were rear-end collision, falling of a car, front-end collision, falling of an airplane in an air-pocket and sudden deceleration of a car in the order of frequency. 3. The admission period were longest in the cases of falling of a car (13.3 days) and shortest in the cases of sudden deceleration of a car (9.4 days). 4. Fifty one (79.7%) were returned to the general activity in two weeks and fifty seven (89.1%) were out of the hospital in three weeks. 5. On admission. the patients were suffered from the symptoms and signs as followings, headache, limitation of the motion in neck, neckache, paresthesia, dizziness and dysphagia in the order of frequency. 6. Roentgenograms show loss of lordotic curve in twenty eight (43.7%) and prevertebral swelling in seven (10.3%). 7. Thirty six (56.3%) were associated with other injuries as followings; multiple contusion, teeth injuries, scalp laceration. There were thirteen cases (36.1%) of cerebral concussion. 8. In all the cases, we used analgegics and muscle relaxants until the neck pain subsided. We had performed cervical traction, hot packs in selected cases. Twelve (18.8%) needed cervical braces or Thomas collar at discharge.

One hundred and thirty trimethoprim-resistant R plasmids derived from of Escherichia coli isolated from clinical specimens and feces of healthy collegians were examined for incompatibility, EcoRI endonuclease restriction fragment pattern, and Southern hybridization with DHFR I, II, III, V, and VII probe. 1. Most trimethoprim-resistant R plasmids were resistant to ampicillin, tetracycline, chloramphenicol, gentamicin, and kanamycin, and showed multiple drug resistance and various antimicrobial resistance patterns. 2. Trimethoprim-resistant R plasmids ranged from 90 to 50 kilobase and 42.3% of R plasmids tested were classified to incompatibilty group Inc FI, Inc FII or Inc FIV, 3. Among 48 random selected R plasmids from various origin, 14 R plasmids (including 9 of 14 Inc FII plasmids and 3 of 14 Inc FI plasmids) hybridized with DHFR VII oligonucleotide probe but others did not respond to any of DHFR probes used. 4. Most R plasmids showed various EcoRI endonuclease fragments and different reaction sites by Southern hybridization. Six plasmids showed identical or nearly identical molecular weight, EcoRI endonuclease fragment patterns and different sites of Southern hybridization. But 2 Inc FII plasmids derived from urine and feces showed identical pattern. These findings, if confirmed by further studies, suggest that normal flora E. coli can act as reservoir of resistant genes and, consequently, as a factor in the dissemination of these genes among enteric pathogens and need to be examined further.

Rupture of Achilles tendon was first reported by Pare, 1575 and thereafter the cause and the diagnostic and therapeutic methods of the ruptured tendon have been described by many workers. Rupture of the Achilles tendon is often wrongly diagnosed and inadequately treated by the doctor who first sees it, with consequent problems of treatment and prognosis. In this paper 24 patients(25 cases)

Congenital dislocations of the hip are all present at birth. Therefore if adequate examination of all newborn infants is done regularly, it should theoretically never be seen in adolescents or adults. Both the pathogenesis and management of congenital dislocation of the hip remain controversial topics. Closed reduction of simple congenital dislocations of the hip with retention in frog position was introduced by Lorenz. After this great efforts to receive these patients for treatment as early as possible were made by investigators. Also numerous surgical procedures and modifications have been used. Congenital dislocations of the hip were known to be uncommon in Korea. Nevertheless adolescents with untreated dislocations were not rarely met. The author studied congenital dislocation of the hip for sex incidence, X-ray findings, birth history, relation with combining anomaly and the results of treatment, In this study, 39 cases of congenital dislocation of the hip, treated at the Orthopedic Department of Severance Hospital during 7 years and 6 months from July, 1970 until December, 1977, were reviewed. The results of this study are as follows: 1. The annual number of the patients who were treated at Severance Hospital has not changed markedly. 2. The number of female patients was much greater than males. The ratio of female to male was 9 to 1. 3. The incidence of bilateral involvement was relatively low compared to the western coutries. 4. Congenital anomaly associated with congenital dislocation of hip occurred in about 7.8%. 5. The acetsbular index, C-E angle, Y-coordinate and height on affected hips are aggrevated according to the increment of age. 6. Closed reduction was satiafactory in 16 cases among 22 cases under the age of 3, but 4 cases were treated by operation. 7. Open reduction was performed in 8 cases, Salter's innominate osteotomy in 8 cases, Colonna's capsular arthroplasty in 2 cases, and supracondylar osteotomy in 2 cases.
