Anthrax toxin consists of three separate proteins, protective antigen (PA), edema factor (EF), and lethal factor (LF). PA binds to the receptor on mammalian cells and facilitates translocation of EF or LF into its cytosol. PA is the primary component of anthrax vaccines. In this study we purified PA from culture filtrates of Bacillus anthracis. The purification involved sequential chromatography through hydroxylapatite, DEAE-Sepharose CL-4B, followed by Mono-Q. The purified PA was judged to be homogeneous on SDS-PAGE, and consisted of a single polypeptide chain with a relative molecular weight of 85,000.

Cutaneous metastases from internal carcinomas are relatively rare, especially from pancreatic carcinoma. Pancreatic carcinomas are usually adenocarcinomas which arise in the head of the gland, and are known to rapidly metastasize to the lymphatic system by permeation and embolization. We report a case of cutaneous metastasis from pancreatic adenocarcinoma. in 74-year-old male patient who have two pea sized, slight erythematous nodules on the lower abdomen and posterior side of the neck.

5.Removal of a broken needle using three-dimensional computed tomography: a case report.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2013;39(5):251-253
Inferior alveolar nerve block obtained maximum anesthetic effect using a small dose of local anesthetic agent, which also has low a complication incidence. Complications of an inferior alveolar nerve block include direct nerve damage, bleeding, trismus, temporary facial nerve palsy, and etc. Among them, the major iatrogenic complication is dental needle fracture. A fragment that disappears into the soft tissue would be hard to remove, giving rise to a legal problem. A 31-year-old woman was referred for the removal of a broken needle, following an inferior alveolar nerve block. Management involved the removal of the needle under local anesthesia with pre- and peri-operative computed tomography scans.

In spite of highly advanced technology in orthopaedic field, management of femoral neck fracture presents difficult problems due to frequent non-union or avascular necrosis of femoral head even with adequate treatments. Intracapsular fracture of the femoral neck heals in the same way as other intra-articular fractures only by endosteal and not by periosteal repair. Avascular necrosis occurred in one-third of displaced fractures with more than a two-year follow-up and is the most serious remaining factor affecting the result. Many attempts have been made to achieve early diagnosis of nonunion and avascular necrosis of the femoral head. Yet, there is still no reliable clinical method of early detection of the union of femoral neck fracture and the viability of the femoral head. For the early detection of union and viability of femoral head, we performed femoral trochanteric intra-osseous venographic technique. Intraosseous venography was performed in 19 cases of femoral neck fractures in the orthopaedic department of National Medical Center during the period from Jan. 1979 to Dec. 1981. The results were as follows: l. 19 patients of femoral neck fracture were performed osteomedullography. Intra-osseous venous flow across the fracture line was seen in 11 cases from 19 patients. 2. Intra-osseous venous flow across the fracture line was seen between the 6th and 12th week following fracture treatment in rigid fixation and adequate reduction. 3. Osteomedullography is considered as very important study for the early diagnosis of the fracture healing and non-union.

One may sometimes complicated with non-union of the tibia with intact fibula or comparatively early united fibular fracture during the cause of treatment of crural fractures. So that the fibula is to strut the tibial fragment preventing effective contact. Several authors have sporadically reported the removal of a portion of fibula may increase potential compression force across the tibial fracture site and promote bony union of non-delayed union of the tibia. Partial fibulectomy was performed in 9 patients with established nonunion of the tibia at National Medical Center from 1975 to 1982. The results were as follows: 1. Healing occurred in 8 of the 9 cases, and average time to union was 7.4months after fibulectomy. 2. In one case performed B-K amputation due to intractable infection after partial fibulectomy. 3. The average shortening of the involved lower limb was about 1.9cm. 4. All cases did not have significant symptoms at the fibulectomy site after union. 5. Partial fibulectomy proved to be a relatively effective method for the treatment of nonunion of the tibia.

We carried out animal experiment in order to determine the effect of resection of nerves, muscles and tendons on the induction of osteoporosis. One hundred and forty rats, weighing approximately 250 gm, were divided into seven groups. In Group I, as a control group, the three skin incisions, one on the anterior aspect of the knee, one on the anteromedial aspect of proximal thigh, and one on the posterior aspect of proximal thigh were made and wounds were sutured. In Group II, the patellar tendon and the extensor digitorum longus tendon were divided to disable knee extension. In Group III, all the knee flexors were divided. In Group IV, all the knee extensors and flexors were divided. In Group V, the femoral nerve was divided to disable knee extension. In Group VI, the sciatic and obturator nerves were divided to diable knee flexion. In Group VII, the sciatic, and obtrator nerves were all divided. Before the procedures, bone density was measured by photon absorptiometry and postoperatively, the measurement was repeated every two weeks until the eighth week. At the time of each measurement, two rats were sacrificed out of each group and were submitted to microphotographic measurement of the tibial cortices. The results were as follows. l. In the muscle and tendon resection groups (Group II, Group III, Group IV), the bone density significantly decreased two weeks after operation and then, gradually increased four, six and eight weeks. 2. In the nerve resection groups (Group V, Group VI, and Group VII), the bone density decreased significantly two and four weeks after operation and then gradually increased six, and eight weeks after operation. 3. In both motor resection and denervation, the paralysis of both flexors and extensors of the knee, caused more decrease in bone density than the paralysis of either flexor or extensor. 4. In the muscle and tendon resection groups, the bone density was significantly more decrease two weeks after operation when the flexors were resected, but thereafter there was no significant difference between the flexors and extensors resection. In the nerve resection group, the paralysis of knee flexors caused more decrease in bone density than the paralysis of knee extensors throughout the entire experimental period. 5. The nerve resection groups demonstrated significantly more severe loss of bone density than muscle and tendon resection groups throughout the entire experimental period. 6. The values of bone density measured by photon absorptiometry correlated well with the cortical thickness indices. Bssed upon these observations, we came to the following conclusions. 1. The osteoporosis following injuries of the nerve, muscle, and tendon is most significant at two weeks after injury. 2. Denervation causes more severe osteoporosis than muscle and tendon injuries. 3. It is suggested that the photon absorptiometry is a reliable means in the evaluation of the osteoporosis.
