    Urist, M. R. derronstratcd that a specific pi otein obtained fiom Lone matrix had osteogenesis, and named it as a Bone Morphogenetic Protein (BMP).
    In the present study, Urist method was employed to obtain crude BMP which was then implanted into mouse thigh muscle. Histological, enzyme histochemical, and immunohistochemical studies were employed to observe the osteoinductive process caused by BMP.
    Three days after implantation, a number of undifferentiated mesenchymal cells proliferated and the BMP implanted area was surrounded by the cells. Positive staining for laminin was found in the basement membrane of muscle fibers, and the cells adjacent to the basement membrane of myofibers also showed positive staining for laminin. At this time, both ALPase and ACPase were not active. From the electron micrographic features, dividing satellite cells and isolated mononucleate cells which migrated from myofiber were confirmed.
    Five days after implantation, spindle shaped undifferentiated mesenchymal cells became round in shape. Only ACPase reaction was found in the boadering area of BMP pellet.
    One week after implantation, undifferentiated mesenchymal cells in the proximity of BMP pellet developed into round shaped chondroblasts, and formed the chondro-matrix. Proliferating and resting chondroblasts were found by electron microscopy and a phagocytotic action by monocytotic cells was also found in the proximity of BMP pellet. At this time, both ACPase and ALPase were active.
    Two weeks after implantation, calcification of the chondro-matrix had started from a bordering area. Many phagocytes and chondroclasts appeared to reabsorb the cartilage.
    Three weeks after implantation, cartilagnous ossification further progressed and developed osteoid and bone marrow like tissues.
    Four weeks after implantation, bone remodering of a newly formed matrix existed with evidence of bone reabsorption.
    Six and eight weeks after implantation, bone reabsorption still continued.

    The healing process and morphologic changes of the temporomandibular joint (TMJ) after complete diskectomy in rabbits were investigated histologically and histochemically.
    The results obtained were as follows:
    1. Immediately after diskectomy, the cartilage on the articular surface of the TMJ disappeared, and the subchondoral bone was exposed.
    2. In 4 weeks postoperatively, proliferation of cartilage cells was observed in the adjacent cartilagious tissue along with the exposed subchondoral bone lesion, while in the deep layer of cartilage, there was a finding of disturbed endochondral ossification.
    3. In 6 and 8 weeks after diskectomy, there was no evidence of cartilagious repairing in the exposed subchondoral bone. The articular surface was depressed, and covered with a fibrous connective tissue presumably originated from mesenchymal cells. As a result, the outline of the articular surface became smoother in 8 weeks postoperatively than in the earlier period.
    4. In the long term observation on 24 weeks survived rabbits after diskectomy, cartilage formation was found in the retrodistal region, and a degenerative change in the osseous-cartilagious components was observed.
    5. In the condition after diskectomy, morphologic changes and healing process of the TMJ took place with reconstruction of the mandibular head and the manibular fossa, resulting in a functional remodeling.

    The effect of stimulation with continuous small amounts (15.5 microamperes) of electric current on the tibial periosteum of male Wistar rat was examined by 3H-thymidine autoradiography.
    The autoradiographic study consisted of the following two methods; flash labeling and single pulse labeling methods.
    Three treatment groups were established for the flash labeling method: In the first group, rat tibial periosteum was electrically stimulated with 15. 5 micro-amperes of constant direct current using wires made of silver and stainless steel twined round the tibial periosteum. The second group consisted of the wires only without electric stimulation as a control. In the third group, a non-treated periosteum was also established as a control. The animals in each group were sacrificed 1, 6, 12 and 18 hours, and 1, 2, 3, 4, 5, 7, and 10 days after initiation of electric stimulation and 3H-thymidine (74 KBq/g) was administered 1 hour before sacrifice.
    Two treatment groups were established for the single pulse labeling method; The first and second groups were similar to those established for the flash labeling method without a third non-treated control group. Then 3H-thymidine (74 KBq/g) was administered 24 hours after electric stimulation and the animals were sacrificed immediately, 1, 2, 3, 4, 6, and 9 days after the administration.
    This experiment revealed that a constant electric stimulation to the periosteum was effective for cell's differentiation to form electric callus. The electric stimulation began to proliferate osteoprogenitor cells from the cellular periosteum, followed by differentiation of osteogenic lineage cells and osteoblasts for osteoid formation. After that, the osteoblast matured to osteocytes within mineralized bone tissue.

    To clarify the significance of fingertip plethysmogram as an intraoperative monitor, changes in the blood catecholamine level and the fingertip plethysmogram were measured with time. These measurements were compared under local anesthesia during the extraction of an impacted mandibular third molar. A total of 60 subjects were selected for the study of which 40 were without any abnormality in their cardiovascular system and the remaining 20 had an impacted mandibular third molar. All subjects were healthy adult males with their ages ranging from 20 to 30 years old.
    The following results were obtained through this experiment.
    1) The subjects showed no marked changes in the blood catecholamin level and the fi ngertip plethysmogram under local infiltration anesthesia induced by 2% lidocaine.
    2) The subjects showed a significant increase in the epinephrine and norepinephrine levels, average arterial pressure, and pulse rate under local infiltration anesthesia induced by 1/80, 000 epinephrin-containing 2% lidocaine. They also exhibited a significant decrease in the wave hight and incisura hight of the fingertip plethysmogram. The norepinephrine level, the average arterial pressure, and the pulse rate decreased rapidly to the levels almost equivalent to the values obtained after rest. In contrast, the elevated epinephrine level and the decreased wave and incisura heights continued over 45 minutes. Since these changes were not observed during the 2% lidocaine-induced local infiltration anesthesia, the exogenous epinephrine is believed to considerably in fluence these changes.
    3) During the impacted mandibular third molar extraction, the subjects exhibited similar changes to those observed during the infiltration anesthesia induced by 1/80, 000 epinephrinecontaining 2% lidocaine. However, the recovery of the epinephrine level and of the wave and incisura bights required approximatery 10 minutes longer during the molar extraction. These results suggest that the influence of endogenous catecholamine was added to the influence of exogenous epinephrine.
    4) There was a significant correlation between epinephrine levels and the wave bights of plethysmogram during infiltration anesthesia induced by 1/80, 000 epinephrine-containing 2% lidocaine and mandibular third molar extraction. These results have clarified the following facts: The blood catecholamine level and the fingertip plethysmogram changed during local infiltration anesthesia and mandibular third molar extraction. These changes persisted even after the recovery of hemodynamics by the autoregulatory mechanism. Finally, the fingertip plethysmogram was well correlated with the blood epinephrine levels.

    Hydroxyapatites (HAPs), which are synthetic ceramics (complex calcium phosphates), are very similar to bone and tooth minerals in their complex and have a biocompatibility. Recently, HAPs are used as a bone implant material in variety of situations, eg, surgical reconstruction, augmentation of the facial skeleton, also used to fill acquired and congenital bone defects.
    Autogenous particulate cancellous bone and marrow (PCBM) had been known to have an active osteogenesis. These implant materials produce desirable effects on regeneration in osseous defects.
    The aim of this investigation was to ascertain experimentally the biocompatibility, osteoinductive and/or conductive ability of a combined implant material with HAP and autogenous bone in an ectopic situation. Mixed type of materials, porous HAP granules and PCBM (volume ratio, HAP: PCBM=2: 1), were implanted into adult dogs using an vessel attached type incubating chamber which enabled to make the circumstances being free from the influences of recipient site. This chamber was attached to bilateral carotid artery, HAP-PCBM mixed group was implanted on one side and HAP alone group on the other side. Periodical (7, 14, 28, 60, 90 days) histopathological examinations were carried out by light and electron microscopies after implantation.
    The results were as follows:
    New bone formation was not observed in HAP alone group throughout the experimental period (90 days). Implanted HAP was encapsulated with fibrous tissue and these tissues were infiltrated with a few inflammatory cells. Macrophages and multinuclear giant cells (MGC) were observed on the HAP-tissue interface (MGC, I supposed to be a fusion cell type of macrophage). HAP resorption occurred by the activities of macrophage and MGC.
    After 28 days, a newly formed calcified bone matrix surrounded by transplanted trabecular bone chips was observed in HAP·PCBM group. These new bones, initially grew toward the HAP granules, were formed along with the HAP's surface. The osteoconductive ability of HAP in an ectopic site was also confirmed with this results. Under the same experimental conditions, a lamellar bone formation, which was a matured type of bone formation, was confirmed after 90 days.
    MGC have a different ultramicroscopical features depending on the contact materials. Namely, MGC surrounding a newly formed bone matrix had a ruffled border and clear zone, which were characteristic in osteoclast, but N1GC around HAP or transplanted bone chips had not such organelles.

    A Study was made on the effect of wide mouth opening on the rat temporomandibular joint synovium ultrastructurally.
    A metal mouth prop was placed between rat's front teeth in order to induce the wide mouth opening at a distance of 6mm or 16mm. The mouth was opend for 3 hours everyday, for 1, 2, 3 and 5days. From immediately to 60 days after treatment the animals were sacrificed and examined electron microscopically. Ultrastructurally, fibrin or fibrinoid formation was seen immediately after 3 or 5 days wide mouth opening at a distance of 16mm. The fibrin or fibrinoid deposition was incorporated and digested by means of type A cells.
    It was suggested that the wide mouth opening induced traumatic synovitis in the rat temporomandibular joint.

    A retrospective analysis of 130 cases of maxillary neoplasms including upper gum, hard palate and maxillary sinus was performed at the Second Department of Oral and Maxillofacial Surgery of Tokyo Medical and Dental University during the period from 1975 to 1987.
    The age of the patients ranged from 9 to 86 years, and the mean age for patients with upper gum, hard palate and maxillary sinus carcinomas was 57.7, 56.6 and 57.9 years respectively. The male to female ratio of maxillary neoplasm was 1.45:1 but that of hard palate was 0.82:1 showing a female predominance.
    The histopathological classification was as follows: 116 cases (89.2%) of squamous cell carcinoma, 6 cases (4.6%) of malignant melanoma, 3 cases (2.3%) of sarcoma, 3 cases (2.3%) of malignant fibrous histiocytoma and 2 cases (1.5%) of malignant lymphoma. In the three regions examined, approximately 80% of upper gum and maxillary sinus carcinomas were of squamous cell carcinoma, but various types were included in the cases of hard palate carcinoma.
    The location and the size of tumor were determined from the physical and radiological findings and described according to the UICC 1987 staging system. In the upper gum alai hard palate the majority were T2 or T4 tumors, on the contrary in the maxillary sinus, the majority were T3 or T4 tumors. The most patients of upper guru and hard palate carcinomas received a surgical treatment only, but in the case of maxillary sinus carcinoma patients were mainly treated with trimodal combination therapy (surgry+radiation+intraarterial infusion). The 5-years cumulative survival rate for each region of hard palate, upper gum and maxillary sinus was 78%, 60.9% and 34.7% respectively. The initial local tumor control rate for each region was also high in the hard palate and upper gum as 76.4% and 71.7% respectively, whereas rather low in the maxillary sinus as 44.7%. Therefore, this local tumor control rate may influence the survival rate.

    We encountered a case of Basal cell nevus syndrome in which multiple cysts occurred during long-term follow-up.
    The patient was a 8-year-old boy. Frontal and temporal bossing, ocular hyperterolism, mandibular prognathism, multiple jaw cysts, pit, calcification of the flax cercbri and bifid-rib were observed.
    Primordial cyst in tire kit maxilla and follicular cysts in the bilateral mandible were confi rmed 4 years after the operation for the left mandibular cyst. From the histopthological investigation, the process of cyst formations in this ease seemed to be identical with Broca's theory. The growth of the cysts was rapid in a short period of 1-2 years.
    We performed an enucleation with closure for the c ysts in the maxilla and enucleation with packing open for those in the mandible. No recurrence has occurred up to now, but a long-term follow-up is required in consideration of occurrence and recurrence of the cyst.

    Dermoid cyst is a developmental anomaly which arises from inclusions of displaced embryonal epithelium. It usually appears in the soft tissue and is of extremely infrequent occurrence in the bone.This report describes a case of dermoid cyst which arises in the mandible of 4 year-old male. The patient visited another hospital complaining of inflammatory swelling of the face. Radiographic examination revealed multilocular radiolucent area in the mandible and the patient was referred to us for further examination. Following marsupialization, the cyst was surgically removed under general anesthesia. The cyst was histologically composed of highly keratinized squamous epithelium and adnexal skin structures; sebaceous glands and hair follicles The cyst appeared in a very low-aged patient and had no relation with dental follicles. From these findings, the final diagnosis of true intraosseous dermoid cyst in the mandible was made.

    An 8-year-old boy with subacute necrotizing lymphadenitis (SNL), a disorder initially described in Japan, is presented. This entity is usually said to have such representative clinical symptoms as lever-up, swelling of lymph nodes, and leukocytopenia. The disease is a non specific inflammation, although it has necrotized lymph nodes, like malignant neoplasm on one side but a specific inflammation from the histopathological point of view on the other side. And this lesion exists mainly in the cervical lymph node.
    At the same time, we review the japana Centra Revuo Medicina (1984-1988) to pick up all the case reports of this entity, in order to clarify the clinical findings of this lesion.

    The effect of cold vasodilatation after refrigeration on the lower lip area of 41 patients suffering from diagnosed sensory paralysis was evaluated. This results were compared with those of 20 healthy subjects.
    1) “The effective data group” the difference in the skin temperature rise between the contracted side and the other normal side was seen in 82.9% of the patients examined.
    The skin temperature difference was seen between 2 minutes and 4 minutes after refrigeration.
    2) The negative data on the skin temperature rise of the contract side being quicker than the normal side was seen in 5 patients. These results were found in the patients who complained of hypersensitivity.
    3) The no effect data group with no difference in the skin temperature rise occupied 17.1% of the total case. All patients of this group were older cases.
    4) “In the healthy group”, the difference in the skin temperature rise between the two sides was not seen.
    From this experimental study, the cold vasodilatation test seems to be useful in the examination of lower lip sensory paralysis.

    A case of eosinophilic granuloma occuring in the mandibular of a 6-years old boy was reported.
    In the histopathological examination of extirpated material, eosinocyte infiltrates and increased histiocytes in the connective tissue and Langerhans cell granules were observed by electronmicroscopy. Histiocytosis-X cells showed a positive reaction to S-100 protein by PAP method. These results suggested that the histiocyte of eosinophilic granuloma was derived from T-zone histiocyte.
    We performed both surgical therapy and combination chemotherapy of prednisolone and Vinblastin. No recurrence was observed in 2 years and 6 months follow up, but a long term follow up study at least for 5 years would be necessary for early detection and adequate treatment of recurrence.

    Mucoepidermoid tumor is found in a high incidence in adults, however, in a relatively low incidence in children. We reported a case of mucoepiderrnoid tumor originated from the minor salivary gland in a 13-year-old girl.
    The patient visited us with complaining of the swelling in the palate. Under general anesthesia the tumor was resected and the clinical course is good.
    Histological findings revealed that this case was Grade II according to the Komori's classification.
    We also referred to 34 cases of mucoepidermoid tumor in the First Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tokyo Medical and Dental University during past the 14 years from 1976 to 1989. The incidence of the mucoepidermoid tumor in children was only 5.9% (2/34) and clinical courses of them are good. The five year survival rate of all the 34 cases was 82.5%.
    Eventhough the prognosis of the mucoepidermoid tumor is statistically good, the present case seems necessary to follow-up for a long time, considering the moderate differentiation of the tumor.

    The patient was a 36-year-old male, complaining of ulcer of the hard palate. A demarcated ulcer appeared in the middle area of the hard palate. The ulcer was covered with a necrotic tissue of yellowish white color. The shape of the ulcer was irregular and its size was 25mm in length and 18mm in width. The right nasal cavity was swollen edematously. X-ray films revealed that the nasal cavity, maxillary sinus and ethmoid sinus on the right side were filled with soft tissues. So-called progressive gangrenous rhinopathy was clinically suspected. The biopsy specimen from the ulcer of the palate showed malignant lymphoma and further examination using imrnuno-histochemical method disclosed T-cell lymphoma.
    Following chemotherapy (prednisolone and cyclophosphamide), radiation therapy (60Co-γ ray, 5, 100 cGy) was done. However, both therapies were ineffective and the patient died of hepatopathy 3 months after initiation of therapy.

    Foully-three cases of the buccal niucosal carcinoma were reviewed. The average age of the patients was 65.5 years old indicating many of them is in rather older ages. Most of the cases were squamous cell carcinoma.
    About half of the cases were in T2, 79% of the cases were in NO, tikl all eases were in MO by TNM classification.
    Thirty-nine treated cases were studied for further clinical analysis.
    Initial treatments were consisted of radiotherapy alone in 21 cases, combination therapy by both radiation and surgery in 5 cases and surgery alone in 13 cases and the primary tumor control rate of each therapy was 61.9%, 60.0%, and 61.5% respectively. All eight cases of T4 lesion showed a local recurrence.
    Regional lymph node metastases were observed in 38.5% with 8 cases found at the initial examination and 7 eases later on. Neck dissection was performed in 11 c.tses, but a final control of the regional metastases was obtained in 36.4% of the patients who had regional metastases. The tumor recurrence rate was analyzed with a histological pattern of invasion in 27 cases of squamous cell carcinoma.
    Recurrence in the primary sites was inevitable in 4C and 4D types, and the average day of disease-free survival in these types was very short. The five years cummurative survival rate of all treated patients was 50.6% by Kaplan-Meier's method. No five years survived ease was obtained in patients with T 4 lesions, positive regional metastases, 4C or 4D types in mode of invasion.
    Prognostic factors of carcinoma of the buccal mucosa were discussed. T 4 lesion, invasive type lesion originating from the retromolar area, 4 C or 4 U type in mode of invasion were considered to suggest poor prognosis. A wide combined excision including elective neck dissection is recommended for further improvement of the cases indicating these poor prognostic factors.

    A case of peripheral T-cell malignant lymphoma (clinical stage IE) arising from the oral cavity analysed histopathologically, immunohistochemically and molecularbiologically is reported.
    A 77-year-old man visited our hospital with complaints of swelling and spontaneous pain of the right molar region of the mandible. Physical examination revealed a swelling with ulcer formation on the right mandibular molar alveolar gingiva. A biopsy from the gingiva showed malignant lymphoma (Malignant lymphoma, large cell, immunoblastic, polymorphous: WF classification, Diffuse lymphoma, pleomorphic type: LSG classification).
    As a result of immunohistochemical examination, this tumor was CD 25, CD 71, HLA-DR antigen expressed helper/inducer T-cell lymphoma. Molccularbiological examination with polymerase chain reaction (PCR) and southern blotting method indicated that this tumor did not involve human T-cell lukemia/lymphoma virus type-1 (HTLV-1) genorne. Although the tumor disappeared after local irradiation, the patient died of pneumonia in 11th month following fist visit.

    We correlated the arthrographic findings of the interior joint space with the magnetic resonance imaging in 3 patients of anterior displacement of the meniscus with reduction and 6 patients without reducnon.
    Displacement of the meniscus was demonstrated by arthrography and MRI. Deformity of the meniscus was better revealed by MRI, but not by arthrography. Perforation or fibrous adhesion of the meniscus was not shown by MRI.
    Because it is difficult to diagnose a soft tissue derangement of the TMJ based on clinical symptoms, arthrography and NIRI Firlp to accurately diagnose in internal derangement of the TMJ.

    Postherpetic neuralgia (PHN) is a distressing condition winch occurs after suffering from herpes zoster and it resists conventional therapies such as administration of painkiller or carbamazepine, nerve block, acupuncture and so on.
    We have successfully treated a patient with PHN on the trigeminal nerve by iontophoresis, whose pain could not be alleviated by conventional therapies. Methylprednisolone and lidocaine were directly permeated into the painful skin area by iontophoresis. A significant relief of the pain was observed soon after the first application of iontophoresis and the pain disappeared after the second therapy. Moreover, there was no side effect.
    We believe that iontophoresis is a valuable method for treating the pain in PHN winch showed no improvement by conventional therapies.

    Fracture of the mandibular head occurs rather frequently, and its symptoms, diagnosis and treatment are well documented. However, little is known about the intra-articular injury that unavoidably occurs when the mandibular head is fractured. In this study, we evaluated the time-related changes in the morphology of the intra-articular cavity in a case of displaced fracture of the mandibular head. For evaluation, we relied mainly on arthroscopic pictures and double-contrast computed tomography.
    A 46-year-old woman had an epileptic seizure and fell down a flight of stairs. She was transfered to our hospital and diagnosed as having fractured unilateral mandibular heads. Changes in the intra-articular morphology with time were monitored by double-contrast CT before, during and after treatment. Arthroscopic surgery was performed to repair the fibrous ankylosis and the backward traction of the articular disc. As the intra-articular injury healed, the joint cavity shrank and eventually disappeared. The articular motility almost returned to the normal range.

    Chronic sclerosing osteomyelitis of the temporomandibular joint is considerably rare. We report a case of a 73-year-old man treated for chronic sclerosing osteomyelitis of the condylar process.
    The lesion was noticed as a clicking of the right temporomandibular joint. At the time of his visit, a tumor lesion was diagnosed from the radiographic appearance. The lesion was removed completely under general anaesthesia. The histopathological diagnosis of chronic sclerosing osteomyelitis was made. The postoperative course was good and no recurrent sign was seen almost one year and nine months after operation.
