  • A method for induction of multiple shoots using cotyledonary nodes and shoot tips of Macrotyloma uniflorum (Lam.) Verdc. was described. The experiment was conducted in which shoot induction was noticed on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of four cytokinins (KIN, 2iP, Ads, BAP). These multiple shoots were later developed into normal shoots. The highest rate of shoot proliferation came from MS medium added with BAP 1.5 mg/L. The multiple shoot buds were subcultured into MS medium with BAP (0.5-1.5 mg/L) along with Ads (1.0 mg/L) and GA$_3$ (0.5 mg/L), which gave rise to the highest frequency of shoot proliferation and elongation. The shoots were rooted on MS medium supplemented with 1.75 mg/L IBA.

  • The nose, a striking features of the human face, is regarded by many clinicians as the keystone of facial esthetics. Clinically, as the treatment of a dentofacial deformity, the soft tissue changes that occurred normally with movement of the skeletal bases. Changes of the soft tissue in the maxillary orthognathic surgery are widening of alar base, elevated nasal tip and flattening of upper lip. In addition, soft tissue change is difficult to predict, it has considerable variability in the response of soft tissue. We reviewed patients who received Le Fort I advancement osteotomy in our department and analysed preoperative and postoperative alar base width, nasal height in clinical measurement and cephalometry and patient's satisfaction of postoperative nasal appearance.

  • A pressure sore wound is often extensive or complicated by local infection involving adjacent soft tissue and bone. In this case, a regional flap after simple debridement is not adequate. Here, we present a case of an extensive pressure sore in the sacral area with deep tissue infection. A 43-year-old female patient with a complicated sore with deep tissue infection had a presacral abscess, an iliopsoas abscess, and an epidural abscess in the lumbar spine. After a multidisciplinary approach performed in stages, the infection had subsided and removal of the devitalized tissue was possible. The large soft tissue defect with significant depth was reconstructed with a free latissimus dorsi musculocutaneous flap, which was expected to act as a local barrier from vertical infection and provide tensionless skin coverage upon hip flexion. The extensive sacral sore was treated effectively without complication, and the deep tissue infection completely resolved. There was no evidence of donor site morbidity, and wheelchair ambulation was possible by a month after surgery.

  • Open calcaneal fracture with more than lateral half of bone loss and soft tissue defect occurred in 17 year-old male patient due to motor vehicle accident. Soft tissue defect included heel pad, peroneal tendon. Bone loss involved mainly most part of inferior tuberosity but not subtalar joint. Open dressing and debridement were done daily in operating room and antibiotics administration was started. After granulation tissue formed, femoral head allograft was performed and fixed with 6.0 mm screws to replace bone defect. Soft tissue defect was covered with latissimus dorsi musculocutaneous free flap. No sign of infection nor major osteolysis was observed in 15 months follow up period. Soft tissue defect was covered with latissimus dorsi musculocutaneous free flap.

  • A mucogingival grafting procedure has been developed to cover denuded root surface. The subepithelial connective tissue graft technique is very predictable and allows for a good esthetic results and minimum patient discomfort on the palate. However, in areas where there is a lack of vestibular depth and keratinized attached tissue, the presence of frena or heavy muscle attachment, covering the connective tissue graft with a mucosal flap is very difficult. The purpose of this study is to evaluate an alternative technique of root coverage using the free connective tissue graft. The results were as follows: 1. Probing depths didn't seem to vary significantly from the preoperative to postoperative period. 2. The amount of keratinized tissue showed an increase of $5.9{\pm}0.97mm$ from the preoperative level. 3. Total clinical exposed root coverage increase 72.2% compare with preoperative level. 4. The shrinkage from gingival margin is $4.2{\pm}1.15mm$ and the mean shrinkage rate is 40.1%. 5. The depth of the vestibule increased with the average distance from cementoenamel junction to mucogingival junction being $7.4{\pm}1.65mm$.

  • Experimental studies were performed to investigate the effect of Houttuyniae herba Aqua-acupuncture on the growth of Melanoma 816 tissue and Mononuclear cell subsets in mice. The results are as follows : 1. In the study of lymphocytes numbers in mice circulating blood, Houttuyniae herba Aqua-acupuncture showed inhibitory effect, but without stastistical significance. 2. In the study of $CD4^+$ T cell percentage in mice circulating blood, Houttuyniae herba Aqua-acupuncture showed inhibitory effect, but without stastistical significance. 3. In the study of $CD8^+$ T cell percentage in mice circulating blood, Houttuyniae herba Aqua-acupuncture showed inhibitory effect, with stastistical significance. 4. in the study of lymphocytes numbers in mice spleen tissue, Houttuyniae herba Aqua-acupuncture showed inhibitory effect, but without stastistical significance. 5. In the study of $CD4^+$ T cell percentage in mice spleen tissue, Houttuyniae herba Aqua-acupuncture showed inhibitory effect, but without stastistical significance. 6. In the study of $CD8^+$ T cell percentage in mice spleen tissue, Houttuyniae herba Aqua-acupuncture showed inhibitory effect, but without stastistical significance. 7. In the measurement of melanoma tissue weight, Houttuyniae herba Aqua-acupuncture showed increasing effect, but without stastistical significance. According to above results, it is concluded that Houttuyniae herba Aqua-acupuncture is effective upon immune responses in Melanoma 816 inoculated mice.

  • Soft tissue sarcomas are malignant tumors that arise in the extraskeletal connective tissues of the body. And the clinical behavior of soft tissue sarcomas is characterized by a tendency to extensively invade surrounding soft tissues as well as early metastatic dissemination. Difficulties were encounted when soft tissue sarcomas invade the major vessels. There are a few reprots about the reconstruction of the major vessels after resection of soft tissue sarcomas. We have treated 3 cases of the soft tissue sarcomas involving the major artery. After marginal excision of the tumor mass, the involved major artery was reconstructed with Gortex artificial vessel graft and we could salvage the patient's extremity.
