ABSTRACT
Laparoscopic procedures have been accepted as a safe, effective treatment modalities and are well tolerated by patients. Although incidences of major vascular injuries following laparoscopic procedures are rare, they are important in that they can cause serious morbidity or death. From February 1993 to November 1996, we experienced 3 cases of vessel injury during laparoscopic surgery. In the first case, the right hepatic artery was injured during a laparoscopic cholecystectomy. We converted to open surgery immediately. The second case involved a scrotal hematoma which developed immediately after a transabdominal preperitoneal(TAPP) laparoscopic hernia repair. We opened the inguinal region anteriorly 2 days after the surgery and confirmed the bleeding from the inferior epigastric artery. In the third case, the left common iliac artery was injured during trocar insertion for a laparoscopic appendectomy, and it was unnoticed. One hour after the operation, we had to open the abdomen due to fresh bleeding from the drainage. All three patients had no morbidity or mortality after the definite surgery. We conclude that if there is any suspicion of vascular injuries, immediate conversion to open procedures is mandatory, and appropriate vascular surgical techniques should be applied to lessen the morbidity and the mortality.

The purpose of this study was to investigate the effects of smoking on adult periodontitis after non-surgical periodontal therapy. The study population consisted of 40 patients with moderate to advanced periodontitis. Smokers(n=20) were defined as individuals smoking at least twenty cigarettes per day at the time of the initial examination. The non-smoking group(n=20) consisted of individuals who were not smoking at the initial examination. The average age was 42.4 years for the smoking and non-smoking group. Examination regarding plaque index, gingival index, pocket depth and contrast phase microscope were performed. Evaluation were made at the first, the second and the fourth weeks after periodontal non-surgical therapy. The results were as follows: 1. Clinical indices including plaque index, gingival index, and pocket depth were decreased in both smoking and non-smoking group at the first, the second, and the fourth weeks. Especially, clinical indices of non-smokers were more significantly decreased than those of smokers. 2. Non-motile rods were increased and motile rods were reduced at the fourth week. spirochetes were reduced significantly in the non-smoking group at the fourth week. These results suggest that smoking play a minor role in adult periodontitis after non-surgical periodontal therapy.

Healing of periodontal tissues require the migration and proliferation of gingival fibroblasts and periodontal ligament cells. There is many evidences that the some agents like cytokines and polypeptide growth factors are mediate these cellular events in wound healing. Recently someone is interested in herbal drugs on periodontal tissue healing processes. The purpose of this study was to examine the effects of 4 herbal drugs, Carthami Flis, Moutan Radicis Cortex, Scirpi Rhisoma, Seed of Carthamus tinctorius L. on human gingival fibroblasts and periodontal ligament cells. Periodontal ligament cells and gingival fibroblasts were primarily cultured from extracted premolar with non-periodontal diseases. The powder from extracted herbal drugs were prepared with distilled water. Cells were cultured with DMEM at 37degrees C, 5% CO2, 100% humidity incubator, and treated with each herbal drugs with proper concentration for 1, 2, and 3 days. The cell activity was determined by ELISA reader using MTT assay. There was the most significant elevation in 10(-3)g/ml of almost herbal drugs on cellular activities. The result of this study demonstrated that Carthami Flis, Moutan Radicis Cortex, Scirpi Rhisoma, Seed of Carthamus tinctorius L. appears to have beneficial effect on healing process after periodontal treatment.
