  • Botulinum toxin type A was intramuscularly administered to Sprague-Dawley rats in both single and 28-day repeated dose toxicity studies. In the single dose toxicity study performed at 25, 50, 100, and 200 ng/kg, LD50 was estimated to be 70.71 ng/kg for males and 97.63 ng/kg for females.(omitted)

  • Clostidium botulinum type B가 생성하는 독소를 정제할 수 있는 방법을 연구하였다. 정제과정은 독소를 ammonium sulfate로 배양액에서 침전시켜 추출한후 Polymin P를 처리하여 핵산 및 기타 단백질을 최대한 제거한 후 Sephaex G-I00에서 gel fiItration을 시키고 DEAE-Sephadex로 이온교환 크로마토그래피를 시켰다. 이러한 과정으로 정제된 독소의 회수율은 17%였으며 SDS-polyacrylamide gel electrophoresis 결과 하나의 선을 나타내 동질성을 증명하였다. 정제된 독소의 분자량은 163,000이였으며 $\beta$-mercaptoethanol을 사용하여 환원시킨 결과 분자량 106,000과 56,000의 하위 단위체로 분리되었다.

  • The enzyme-linked immunosorbent assay using the so-called "double-sandwich"technique was applied to determine Clostridium botulinum type F toxin. Polystyrene tubes were coated with horse anti-type F toxin serum and then toxin sample was added. The tubes were subsequently treated with rabbit anti-type F toxin IgG and sheep anti-rabbit serum IgG-horseradish peroxidase conjugate. By this technique, about 10 mouse intraperitoneal 50% lethal doses (ip LD/50/) of type F toxin could be detected. Low back-ground reading was achieved with the use of phosphate-buffered saline containing 0.05% Tween 20 and 1% bovine serum albumin as diluents of rabbit IgG and conjugate. Addition of EDTA in the diluents of toxin increased ELISA extinction value significantly. No cross-reaction was observed with botulinum type A and B toxin, but type E toxin gave sleight cross-reaction.

  • The application of botulinum in oral and maxillofacial surgery begins in 1982, where Jan Carruthers started using it for reducing the muscle mass and smoothing the skin, and since then it has been used for cosmetic purposes. In Korea, it is already being used by various specialties including dentistry (oral and maxillofacial surgery, oral medicine), plastic surgery, dermatology, ophthalmology, general surgery, and orthopedic surgery, etc. Each specialty approaches to Botox with its own medical indications. In this article, we will discuss the maxillofacial application of botulinum toxin, which includes theoretical and practical aspects of such as bruxism and square jaw.

  • Botulinum toxin (BTX) has various therapeutic indications: bruxism, square jaw, facial wrinkle, oral ulcer and maxillofacial pain, etc. In this paper, we will discuss the effectiveness of using BTX in dental implant surgery and orthognathic and orthodontic treatment. We summarized the clinical application of botulinum toxin in the maxillofacial field at the finale.

  • Recombinant light chain of Clostridium botulinum neurotoxin type B stimulated transglutaminase activity in a dose dependent manner, Compared to native toxin, recombinant light chain showed av greater stimulatory effect on transglutaminase activity. Zn-chelating agents, inhibiting the proteolytic activity of the clostridial toxins, did not interfere with this stimulation. These results suggest that the light chain plays a major stimulatory role, which is not due to its metallopeptidase activity, but is possibly due to specific interaction with transglutaminase. More importantly, this report provides a new insight into the intracellular action of C. botulinum neurotoxins.

  • Stuttering is a movement disorder of speech-motor control characterized by inappropriate timing of lingual, labial, laryngeal, and respiratory muscles. Treatment for adult stutterers have included traditional and non-traditional behavioral and psychiatric modalities, many with good initial success but all with limited long-term benefit. Recent trials of botulinum toxin injection was somewhat favorable. In this study, the authors injected 5-8 U of botulinum toxin into the thyroarytenoid muscle bilaterally in cases of disabling stutterers. Evaluation after 4 weeks of injection, 80% of the patients was improved more than one positive scale. However, no one was improved to almostly normal range.

  • The causes of tongue pain and discomfort include systemic disease, malnutrition, mental illness, fungal infection, and neuropathy. Three postmenopausal women reported burning sensations and stiffness of the tongue for various periods, from one month to four years. There were no objective etiological factors to cause the tongue pain and discomfort. Muscular tenderness upon palpation of masticatory muscles, sternocleidomastoid, trapezius, and tongue were observed. Physical therapy approaches such as moist hot pack, ultrasound, and myomonitor were performed on three patients with tongue pain, just as for temporomandibular joint disease. Additional botulinum toxin injection therapy was applied to one patient who displayed a clenching habit. All three patients showed a marked improvement in their tongue symptoms after the muscle relaxation and botulinum toxin injection therapy.

  • Lingual dystonia is an uncommon focal type of oromandibular dystonia that only affects the tongue. Although the use of several treatment modalities has been attempted to reduce involuntary tongue movements, such as anticonvulsants and anticholinergics, the results do not seem promising, and the efficacy of such treatments is unpredictable among patients. This case report describes botulinum toxin injection for a patient with lingual dystonia with favorable clinical results. Botulinum toxin injection to the muscles of the tongue could be an alternative treatment option for lingual dystonia.

  • Six months after undergoing reverse shoulder arthroplasty (RSA) a 73-year-old woman sustained a periprosthetic scapular spine fracture following a fall. She was treated with open reduction and internal fixation (ORIF), followed by botulinum toxin injection into the deltoid muscle to temporarily minimize strain at the fracture. Fracture union was achieved by 3 months, with excellent clinical function more than 1 year following fracture fixation and full resolution of deltoid function. Scapular spine fracture following RSA can be treated with ORIF and temporary deltoid paralysis using botulinum toxin in the immediate postoperative period to safely support fracture healing.
