There has been many attempts to develop a method that can regenerate periodontal tissues that were lost due to periodontal diseasd, but none of them was completely successful. This study was designed to investigate the healing and regeneration of periodontal tissue when bone substitutes such as porous replamineform hydroxyapatite and porous resorbable calcium carbonate were used in combination with oxidized cellulose membrane and collagen absorbable hemostat, compared to a control where only oxidized cellulose membrane or collagen absorbable hemostat were used. Chronic periodontitis was induced on mandibular premolars of and adult dog by placing orthodontic elastic ligatures for 10 weeks. After flap operation, the control group were received oxidized cellulose membrane (control- I )or collagen absorbable hemostat (control- II) only, while one experimental group was given either porous replamineform hydroxyapatite or porous resorbable calcium carbonate in addition to oxidized cellulose membrane (Experimental I-A, I-B), and another experimental group was treated by using either porous replamineform hydroxyapatite or porous resorbable calcium carbonate in addition to collagen absorbable hemostat. (Experimental II-A, II-B) After 56 weeks, healing was histologically analyzed with the following results. 1. Apical migration of junctional epithelium was observed only in areas coronal to the notch for both control and experimental group. 2. Inflammatory cell infiltration was not observed in any groups. 3. Oxidized cellulose membrane and collagen absorbable hemostat were completely resorbed. 4. Newly-formed cementum was observed up to the level where junctional epithelium was located, for both control and experimental groups. 5. Bone formation was limited of the middle portion of the notch in the control group, where as experimental groups showed bone formation up to the level of implant materials coronal to the notch. 6. Minute resorption of apically located portions of implanted materials was observed in experimental group I-B and II-B only.

Backgrounds/Aims: This study aimed to evaluate clinical application of InnoSEAL Plus (a mussel-inspired catecholamine hemostat) as a new hemostatic material for humans. Methods: Patients treated with topical hemostatic patches after liver resection were enrolled. They were divided into an experimental group (InnoSEAL Plus group) and two control groups (TachoSil^® group and Surgicel Fibrillar^® group) for efficacy evaluation. Results: A total of 15 patients were enrolled. Each group had five patients. The 3-minute hemostasis success rate was 80.0% (4/5 patients) in the InnoSEAL Plus group, 80.0% (4/5 patients) in the TachoSil^® group, and 40.0% (2/5 patients) in the Surgicel Fibrillar^® group, showing no significant difference in the success rate among these groups (p > 0.05). All three groups exhibited 100% success rate for 10-minute hemostasis. Both InnoSEAL Plus and TachoSil^® groups had one patient developing adverse events, which were treated easily with drug administrations. Conclusions: InnoSEAL Plus is expected to be functionally not inferior to other conventional hemostatic agents. However, it is necessary to confirm this through multicenter prospective studies in the future.

Objectives : In parotidectomy, facial nerve dissection technique had been evolved for its safety. Surgical landmarks are important and good guides to facial nerve detection. Conventional exposure and release of the nerve requires hemostat for elevation of parotid tissue from nerve and #11 blade for cutting the parotid away from the nerve. Material and Methods : The rolling the parotid tissue over the nerve after dissecting with Metzembaum scissors instead of knife, lessen pulling trauma and nerve cutting by knife. Eleven superficial parotidectomies since June 2009 were done with rolling technique and preliminary report is presented. Results : Total 11 parotidectomies were done using proposed technique with tolerable complications(temporary facial dysfunction in 4 cases). Conclusion : Rolling method using metzembaum scissors could be applied to parotid operation.

Purpose: Surgery on digit requires a clear, bloodless field and it can be achieved by using a tourniquet. Several type of tourniquet have been used including Penrose drains and sterile glove with hemostat. We present a simple digital tourniquet using nelaton catheter, which is easily available, inexpensive, easy-to-apply, and effective for digital surgery. Methods: We made a small incision on the opposite side of an opening at the tip of nelaton catheter. Then the other tip of nelaton catheter is passed through the incision to form a ring. Nelaton catheter is placed aournd the base of the injured finger, making a tight circle to desired pressure. Results: A simple tourniquet using nelaton catheter effectively achieves a bloodless field and allows fine control of the pressure for digital surgery. Conclusion: We present a sismple digital tourniquet using nelaton catheter, which is easily available, inexpensive, tunable, and available for more than one finger.

The purpose of this study was to examine the effect of Ga-As(Gallium-Arsenide, wave length; 904 nm) infrared laser irradiation on healing of the experimentally crush injured rat sciatic nerves. The bilateral sciatic nerves of 43 adult male Sprague-Dawley rats were compressed surgically with a straight hemostat (1 mm width). The right legs of all the rats were irradiated using a 27 mW Ga-As infrared laser (laser irradiated group). The radiation procedure was administered for 3 minutes every day for 1, 3, 5, and 7 weeks in each group. Left legs were not irradiated and served as the control group. The numbers of total myelinated axon and degenerated myelin in the sciatic nerves of bilateral legs were measured and analyzed with mage analysis system in order to make a morphological analysis of the effect of the Ga-As infrared laser on injured nerves. Total number of myelinated axons was increased with time interval, especially in the 1, 3. and 5 week of irradiated group. Conversely, the number of degenerated myelin was decreased with time interval, especially in the irradiated group. The effects in the irradiated group were more pronounced than those of the control group. In conclusion, the Ga-As infrared laser irradiation is a useful adjuvant therapy to the regeneration of the peripheral nerve injury.

Approximately 10 percent of advanced stomach cancer patients have internal bleeding in their stomach. It is crucial to treat internal bleeding since it severely deteriorates patient's condition, and disturbs process of chemotherapy. There are hemostatic agents and dressing, radiotherapy, endoscopic ligation and coagulation, surgical methods to treat bleeding. However, these methods cannot be executed in some cases in which patient is in terminal stage or not in desirable condition to take these treatments. We are going to introduce a case of advanced gastric cancer patient having stomach bleeding who made a choice to take oriental medical treatments. The patient was on third stage of stomach cancer, had 3200cc of blood transfusion for five times. After diagnosed as not being able to have resection, he started to oriental medical treatments to stop bleeding. From March 28, 2009 to April 16, 2009, we administer 120cc Bojungikgi-tang gamibang to the patient in 90minutes after each meal. During 19days of having Bojungikgi-tang gamibang, we observed that the patient needed significantly lower amount blood transfusion, to 640cc. The patient improves in performance, and was able to eat more. Despite of short period of observation, this case indicates that Bojungikgi-tang gamibang treatment to the patient could work as hemostat, further improved quality of patient's life.

Since it was reported that the unusual amino acid DOPA in synergy with lysine and histidine residues found in mussel adhesive proteins plays a pivotal role in mussel adhesion in underwater environments, there has been a burgeoning development of various catecholamines-based adhesives for biomedical applications. Among these, catechol-conjugated chitosan, containing catecholamine, featuring multiple catechol groups within its aminerich chitosan backbone, has found versatile utility in fields, such as tissue adhesion, wound dressing, tissue healing, hemostats, drug delivery systems, and tissue engineering scaffolds. Significantly, chitosan-catechol is a mussel-inspired material approved by both US Food and Drug Administration (FDA) and KR Ministry of Food and Drug Safety (MFDS) for its effectiveness in hemostasis. This review focuses on 1) general aspects of catechol-conjugated chitosan, highlighting catechol group integration into chitosan backbones, 2) examination of proposed mechanisms of hemostasis, and 3) exploration of diverse physical forms, including solution, hydrogels, patches, and thin films with practical applications inapplicable to hemostasis.
