The sinking skin flap syndrome is a rare complication after a large craniectomy. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. In patient with sinking skin flap syndrome, cerebral blood flow and cerebral metabolism are decreased by sinking skin flap syndrome, and it may cause the deterioration of autoregulation of brain. We report a case of a patient with sinking skin flap syndrome who suffered from reperfusion injury after cranioplasty with review of pertinent literature.

In order to effectively utilize fish(Cod, Gadus macrocephalus) bone obtained as fish waste in fish manufactory, the preparation of the fish bone gelatin were attempted by heat extracting method from collagen protein contained in the fish bone. The methods of two kinds pretreatments (the B-type by alkali pretreatment and the E-type by enzyme pretreatment) for fish bone and the optimal extraction conditions to prepare gelatin from pretreated fish bone were investigated. Physical properties and functionalities of the two type fish bone gelatins obtained were compared with the commercial gelatin and the fish skin gelatin. The optimal extraction conditions of the B-type and the E-type gelatins were 5 folds of added water with material(w/w), pH 5.0, 3 hrs of extraction time and 60$\circ$C of extraction temperature. The yield of the B-type and the E-type gelatins were 32.6% and 28.1 %, respectively. The B-type gelatin was superior to the E-type un all physical properties. Molecular weight of the B-type was larger than that of the E-type due to its pretreatment method. Among the composition of amino acids, the amino acids such as glycine, alanine, glutamic acid and imino acids(proline and hydroxyproline) were responsible for 68$\sim$70% of the total amino acids. Functionalities of the fish bone gelatin were almost similar to commercial gelatin.

Bone scan is known to be an effective tool for observing the state of soft tissues and bones of electric burn patients. It is also used for observing the progress of patients after debridement or skin graft as well as deforming to amputate specific body parts. To evaluate bone scan's role in electric burn, we analyzed bone scan 37 patients with electric burn. Among the 37 patients, 8 of 37 were injured in low voltage and 29 of them in high voltage. 27 patients received the electrical input through the hand, 6 through the scalp, 2 through the shoulder, 1 through the left chest wall and 1 through the left inguinal area. Among 29 patients received high voltage, 22 patients had the electrical output through the foot, 3 through the hand, 2 through the shoulder, 1 through the buttock and 1 through the left chest wall. Bone scans revealed cellulitis in 37 patients with 47 sites, osteomyelitis in 15 patients with 15 sites & bone defects in 4 patients with 4 sites. In 4 patients with skin graft or skin flap, follow up bone scan showed improvements of bony uptake in preoperatively bony defect area and all of them were healed without complication. There were 2 cases in which uptake increased in the myocardium, 1 in the liver and 6 in the kidney, however, serum calcium level, EKG, cardiac enzyme, liver and renal function tests were normal. In conclusion, bone scans are helpful in the assessment of injury sites after electrical insult and in differential diagnosis of cellulitis and osteomyelitis. It is also useful tool of assessment after skin graft or skin flap, however, it should be further evaluated about internal organ damage.

Vestibuloplasty are following categories : Mucosal advancement(submucous), secondary epithlization(reepithelization) and grafting vestibuloplasty. Although certain procedures are indicated for alveolar bone loss and sulcus shortening, relapse can occur. Every efforts to minimize or compensate for it is controversy. O'Steen(1970) reported the mucous graft methods that none of vestibular shrinkage and graft contracture. 15patients in mucous graft vestibuloplasty with fibrin adhesive system(Beriplast) were taken in cases of alveolar bone resorption and mucosal shortening due to traumatized alveolar bone defects, senile atrophic alveolar bone, postoperative cyst or tumor resection, edentulous alveolar bone loss, and others. A technique in the use of small piece of palatal mucosa$(1{\times}20mm)$ from the lateral aspect of the palate with adhesive system provided to secure the skin grafts, avoid stent fixation, postoperative patient's comfort and less time-consuming than the standard technique, especially excellent bleeding control.

McCune-Albright syndrome (MAS) is a disease with clinical features such as fibrous dysplasia in which normal bone tissue is replaced with abnormal fibrous tissue, abnormalities in the endocrine system, and cafe-au-lait spots on the skin. Although MAS patients are generally known to have reduced bone healing ability, postoperative healing after invasive surgical extraction is still not clearly known due to its relatively rare occurrence. In this report, a 25-year-old female patient, who had been diagnosed with MAS and had a history of abnormal bone healing after fractures of her extremities, underwent surgical extraction of the mandibular third molar with surrounding bone removal. Postoperatively, the patient showed favorable soft tissue and bone healing at the surgical site without abnormal findings such as newly developed fibro-osseous lesions, postoperative infection, or osteomyelitis.

Menopause is often associated with the incidence of several chronic diseases including osteoporosis, cardiovascular disease, and obesity. Hormone replacement therapy (HRT) is an effective regimen that has been found to prevent these diseases in postmenopausal women. However, HRT is accompanied by an increased risk of unfavorable outcomes. Therefore, this study was conducted to evaluate the effects of Ecklonia cava, a kind of seaweed, extract on bone turnover markers in symptomatic menopausal women. For this study, the following four groups of 9-week-old Sprague-Dawley rats were evaluated over 6 weeks: normal rats (SHAM), ovariectomized rats (OVX-CON) and ovariectomized rats that were treated with Ecklonia cava extracts. The optimum extraction temperature and solvent of Ecklonia cava were found to be $80^{\circ}C$ and 80% ethanol. We measured the osteocalcin and CTx content, enzyme ALP activity in serum and collagen content in the cartilage, bone, skin and lungs. We found that the levels of indicators of bone metabolism such as ALP, osteocalcin and CTx were lower in rats in the Ecklonia cava extract group than the OVX-CON group. In addition, the collagen contents in the bone, cartilage, skin and lungs decreased in response to ovariectomy, but the levels of collagen were greater in the bone of rats that were treated with Ecklonia cava extract than in the bone of rats in the OVX-CON group. According to these results, we were able to know the effects of Ecklonia cava extract on bone aging in ovariectomized rats. Consequently, we expect Ecklonia cava extract to have an effect on bone aging in postmenopausal women.

Body fluid(津液) is a general term for normal mucus in human body, including saliva, gastric juice, intestinal juice and articular fluid in joints as well as tear, running nose, sweat, etc.. The formation of Body fluid goes through two phases. First phase is digestion of food at stomach, and then evaporation and classification of energy at Triple warmer(三焦). More technically speaking, Body fluid is divided into the Jin(津) & the Aek(液). Aek is a very mild and water-like fluid, runs deep into the internal organs. Jin is a thick and sticky liquid, running shallow under the skin or in the joints of limbs. Major roles of body fluid over the body are to moisturize the internal organs, flesh, skin, etc., to soften the joints, to fill the bone marrow, and to balance Yin and Yang. This article deals with the role of body fluid and how to differentiate them, the liquid metabolism in the human body, and the formation and change of sweat, urine, tear, spit, bone marrow, etc.. The imbalance of Yin and Yang and disturbance of Triple warmer's evaporation lead into lumbago, leg weakness and edema is also explained here.
