Osteoarthritic changes in experimental animals has been induced by several different methods. In order to study the changes of the articular cartilage induced by injuries of ligaments and/or meniscus of the knee joints, the author performed the experimental study that section of the medial collateral and anterior cruciate ligaments (group I) and section of the medial collateral and anterior cruciate ligaments combined with excision of the medial meniscus (group II) in twenty adult rabbit's knees caused instability. Histological changes of the articular cartilage were observed up to four months. The results were as follows: 1. The changes of the articular cartilage were gradually advanced depend on the time lapse after experimental procedures, in group I and ll. 2. The changes of the articular cartilage could be noticed from eighth week after experimental procedures in group I and from fourth week in group II, and more severe at sixteenth in group I and at twelfth week in group II. 3. The changes of the articular cartilage in group ll were appeared earlier and more severe than in group l. 4. The changes of the articular cartilage in the medial side of the knee joint were noticed more severe than in the lateral side.

The patient with an anterior open bite has one of the most difficult orthodontic problem to correct Previous studies have yielded different conclusions as to exactly where the morphologic problems associated with vertical dysplasia- high angle cases are located. In order to identify the cephalometric features of high angle cases and highlight the measurements that characterize high angle cases, 109 pretreatment cephalograms, 35 high angle, 37 average angle, and 37 low angle cases, were analyzed and compared statistically. As the mandibular plane was steeper, the anterior facial height, especially lower anterior facial height, became greater, and the posterior facial height became smaller. All the dentoalveolar vertical dimensions, especially in upper, increased. Arid all the skeletal angular measurements increased. Especially Lower gonial angle had most positive correlation to mandibular plane angle. Upper incisor was lingually inclined, and lower incisor was labially inclined in high angle cases.

Many authors have been reported that the abdominal trauma, especially injury of the liver and spleen, is frequently found with lower rib fractures, below the ninth rib fractures and the incidence was about 20 to 30%. In cases of rib fractures, Intra- abdominal organs may be injured in the higher rib fractures than the ninth because the diaphragm is elevated at the level of filth intercostal space in expiration period and the intra-abdominal lesions are often delayed evaluated due to the pain of the fractures and masked by the other injuries of the head and the extremities. So above reasons, we were often questioned what the level of rib fracture we must evaluate the intra-abdominal injury was? So we investigated 452 patients with rib fractures who visited our emergency medical center from 1995, January to 1996, December and divided into two groups according to the prescience of intra-abdominal organ injuries by each the level of rib fractures. The number of patients with intra-abdominal organ injuries were 75(16.6%) and the most frequently damaged organ was the liver(25 cases, 33.3%). We calculated the statistical values of each level of rib fractures by the Chi-Square method and got a result that the level of rib fracture we must evaluate the intra-abdominal injuries was the sixth rib fracture. Therefore, if we will meet the patients with rib fracture below the sixth, we must have attentions to the intra-abdominal injuries and evaluate the abdomen closely with various diagnostic methods.

BACKGROUND: Although a laparoscopic cholecystectomy results in less pain than an open cholecystectomy, it is not a pain-free procedure. A controversy exists over the effectiveness and clinical value of intraperitoneal local anesthetics for treating pain after a laparoscopic cholecystectomy. We investigated the effects of intraperitoneal lidocaine on pain after a laparoscopic cholecystectomy. METHODS: Forty patients were randomly assigned to receive 200 ml saline containing 200 mg lidocaine or the same volume of saline instilled under the right hemidiaphragm and cholecystectomy site at the end of surgery. Intensity of abdominal and shoulder pain were assessed 0, 1, 6, 12, 24 and 48 hours after surgery and recorded on a visual analog scale (VAS) and verbal rating scale (VRS). RESULTS: The abdominal pain scores (VAS and VRS) were significantly lower in the lidocaine group than the control group at 0 - 24 hours after surgery (P < 0.05). The shoulder pain scores and incidence were significantly lower in the lidocaine group than the control group at 6 - 12 hours after surgery. In the lidocaine group, the incidence of epigastric and right flank pain were significantly lower than the control group. CONCLUSIONS: Intraperitoneal instillation of lidocaine significantly reduces shoulder and abdominal pain for 24 hours after a laparoscopic cholecystectomy.
