ジャーナル フリーInfection is one of the serious problems in complications of diabetics and a recent increase in complication of opportunistic infection in diabetics has been brought to our attention. Clinical reports of opportunistic infection in diabetes appear in some reseach papers. However. experimental report of opportunistic infection caused by oral bacteria are rarely found.
In order to have an explication of mechanism in development of opprtunistic infection in diabetes, this writer has studied infectivity of oral bacteria in diabetes through histopathological research to see how presence of diabetes condition affects invasion extent into tissue by infectious oral bacteria.
The results obtained are as follows:
1) It was found that the subcutaneous abscess formation experiment diabetes group in comparison with control group has revealed that the number of bacteria that was unable to form any abscess in control group was recognized to form abscess in diabetes group indicating high rate of abscess formation in diabetes.
2) In intramuscular inoculation experiment, to one degree or another destruction of tissue by any type of bacteria was observed as much higher in diabetes group then in control group.
Accordingly it was concluded from the above that the type and number of bacteria that can not cause infection in healthy subjects will do so in diabetes. After infection is developed in diabetes the invasion extent into tissue is very bad.
Now I see clearly that once it is developed it tends to become serious and prevalent.抄録全体を表示PDF形式でダウンロード (14756K) -

ジャーナル フリーMale Wistar rats were divided into two groups. One group of 42 rats were rendered diabetic by injecting streptozotocin (70mg/kg). The other group of 54 rats served as control. On the sixth day, 6m1 of air was subcutaneously injected into the dorsal surface of the rats and the following day, 4 ml of 2 % carrageenin was injected into the air pouch. The rats were sacrified at 7, 14 or 21 days after carrageenin injection.
In the diabtic group, tissue damage, and inflammatory response were more severe than in the control, though granuloma weight and fluid volume were less than in the control. The diabetic group, therfore, failed to respond adequately against noxous stimuli in the inflammatation healing process.
Low values of plasminogen activator, collagen content and weight of granuloma was associated with the delayed healing process in the diabetic group.
In the diabetic group, high values of FDP, β-galactosidase in fluid on day 7 suggested the inhibition of the formation of fibrin-net by lysosomal enzyme.
Diabetic group showed delays in the inflammation, healing process, and responded insufficiently against noxious stimuli due to the low sensitivity of the inflammed tissue.抄録全体を表示PDF形式でダウンロード (1632K) -

ジャーナル フリーA low grade differentiated mucoepidermoid tumor, derived from the minor salivary gland of the palate, was subcutaneously transplanted into the back skin of the nude mouse. W e succeeded in the passage of transplantation in the nude mouse. The passaged tumors in the nude mouse maintained original histopathologic feature. Viability rate of transplantation was 100%. Light and electron microscopic observation was performed to compare the recurrent tumor in the patient with the passaged tumor in the nude mouse.
In the light microscopic findings, the primary tumor that arose in the palate was the high grade differentiated mucoepidermoid tumor which was rich in mucous secreting cells. However, in the recurrent and the transplanted tumors, mucous secreting cells which were positive in digestive PAS and alcian blue staining were rarely seen. The transplanted tumor was composed mainly of epidermoid and intermediated cells. Moreover, we found an interesting transitional figure in some intermediated cells and some vacuolar degenerated cells. These cells showed mucous substance in their cytoplasm.
In the electron microscopic findings, the mucous secreting cell, the epidermoid cell, the intermediated cell were observed. W e observed the ribosome rich cell, mitochondria rich cell, serous granule cell and the undifferentiated cell as the intermediated cell. Contrary to past reports with regard to ultrastructure of the mucoepidermoid tumor, the mucous secreting cell contained abundant desmosomes and tonofilaments than the epidermoid cells.
We considered that the mucous secreting cell is differentiated or transformed from the epidermoid cell and the intermediated cell.抄録全体を表示PDF形式でダウンロード (20403K) -

ジャーナル フリーHydroxyapatite ceramics (HAP) are assumed to have biocompatibility and osteoconductivity when grafted into bone tissue. The influences of sintering condition and surface shape of HAP-granules on the osteoconductivity, however, have not been well documented. We made the following five samples of HAP-granules and studied their steoconductivity. Sample 1: round shaped granule, Sample 2: irregular shaped granule containing 12% of β-TCP with open micropores, Sample 3: more irregular shaped granule containing12% of-β-TCP with reticular open icropores, Sample 4: irregular shaped granule containing 4% of β-TCP with open micropores, Sample 5: irregular shaped granule containing CaO with open micropores. Each sample was grafted into rabbit tibia and the following esults were obtained.
1) Osteoblasts and new bone were attached directly to the surface of each sample at 2 weeks after implantation.
2) Active bone formation was observed in the micropores of Sample-3, although less bone ormation was found in the micropores of Samples 2, 4 and 5.
3) The quantity of 18-TCP contents didn't influence the early osteoconductivity of HAP.抄録全体を表示PDF形式でダウンロード (11442K) -

ジャーナル フリーAnalyses of teratogenic effects of N-ethyl-N-nitrosourea (ENU) on the craniofacial and central nervous system (CNS) development in the rat embryo were performed. A whole-embryo culture technique was applied and the following experiments were carried out: 1) ENU (70mg/kg) was intraperitoneally injected into the pregnant rat on days 9.5, 10.5, 11.5 and 12.5 of gestation and the fetuses were taken out on day 21; 2) 9.5 day-old rat whole-embryos were cultured for 2 days in the homologous serumconttaining ENU (0-116ng/ml).
Administration of ENU to the pregnant rats on day 9.5 of gestation induced not only CNS but also craniofacial malformations. In rat embryos in vitro, ENU treated groups exhibited failure of neural tube closure, hypoplasia of the frontal prominence, maxillary and mandibular swellings. By light microscopy, decreases in number of neuroepithelial, neural crest and mesenchymal cells were observed. By electron microscopy, numerous cells in the neural fold and maxillary and mandibular swellings displayed nuclear condensation, formation of phagolysosomes and degeneration of mitochondria.
These findings suggest that the craniofacial and CNS malformations are due to degeneration of neuroectodermal cells selectively induced by ENU in the early somite stage.抄録全体を表示PDF形式でダウンロード (21716K) -

ジャーナル フリーA new type of secretory cell was found in the terminal portion of the submandibular gland in rat. In the semithin sections stained with toluidine blue, the cells showed numerous dark secretory granules in thier cytoplasm. Several such cells gathered together to form a pure terminal portion, or gathered with several seromucous cells to form a ed terminal portion. These terminal portions containing the new type of secretory cells tended to form a group onsisting of 5 to 10 terminal portions. Electron microscopically, the cells had well-developed rough endoplasmic eticulum and Golgi apparatus. The secretory granules showed wide ranges of variation in substructure, depending on the cells and depending on the granules even within the same cell. W ell-developed intercellular interdigitation and intercellular canaliculus were also observed. Little is known about biological significance of those cells regarding their nature, sex, age and the properties of secretory granules. The present study clarified that the rat bmandibular gland possessed three types of secretory cells including ordinary seromucous cell, mucous cell and the third type of secretory cell.抄録全体を表示PDF形式でダウンロード (6477K) -

ジャーナル フリーThis paper presents the clinical evaluation of an assumed rare case skeletal mandibular prognathism with multiple impacted teeth.
The patient, a 12-year-old boy, was first referred to our hospital for permanent teeth eruptiondifficulty. Oral findings revealed remains of deciduous teeth except four first molars and one central incisor and two lateral incisors of the mandible with class DI relationship. Further radiographic examination revealed multiple impacted teeth including eighteen supernumerary teeth.
For ten years, prolonged retentive deciduous teeth and impacted supernumerary teeth had been extracted and then retentive permanent teeth had been pulled out orthodontically. For the duration, positive orthodontics had been done for class M malocclusion, but skeletal mandibular prognathism with open bite had appeared. Then orthognathic surgery, which was Le Fort I osteotomy and sagittal splitting osteotomy of ramus was carried out. Consequently, the patient was able to get satisfactory occlusion.抄録全体を表示PDF形式でダウンロード (7137K) -

ジャーナル フリーEighty five cases of epithelial tumor originating from the salivary gland treated in the department of Oral and Maxillofacial Surgery, Kurume University during the past 26 year period from 1961 to 1987 were studied clinically and pathologically.
They were 33 males and 52 females and ranged from 16 to 87 years old.
The primary sites of the tumors were 67 cases in the minor salivary gland (48 palate, 7 lip, 6 buccal mucosa, 4 retromolar and 2 floor of the mouth) and 18 cases in the major salivary gland (13 submandibular gland, 3 sublingual gland and 2 parotid).
They were composed of 57 cases of benign tumors and 28 cases of malignant tumors. Of all benign tumors, 55 cases (96.4%) were pleomorphic adenoma.
Malignant tumors were 11 adenoid cystic carcinoma, 8 malignant pleomorphic adenoma, 8 mucoepidermoid tumor and 1 acinic cell tumor.
Malignant tumors were more in the minor salivry gland.
In the site of the minor salivary gland, all cases in the retromolar and floor of the mouth were malignant tumors.
Also, malignant tumors in the buccal mucosa and lip were found to show a higher incidence than those in the palate.
Most of the patients who complained of pain had malignant tumor.抄録全体を表示PDF形式でダウンロード (1115K) -

ジャーナル フリーThe pathogenesis of the postoperative maxillary cyst was studied by computed tomography in 36 patients with postoperative maxillary cyst which were surgically treated on one side bacause of clinical manifestations following bilateral radical operations of the maxillary sinuses. Both symptomatic and asymptomatic sides of the maxilla were studied preoperatively in all patients and healing process was followed from 1.5 months to 10 years postoperatively in 26 patients.
1. The cysts had been formed along the original shape of the maxilla and had caused little bony expansion in most cases.
2. The cysts were present adjacent to the nasal cavity in all cases.
3. Air-containing residual cavities with communication to the middle meatus were found in 8 cases (22.2%). They were located anterosuperiorly to the cysts and were in no case communicated to the lower meatus.
4. The maxilla on the asymptomatic side was filled in with bone in 41.7% of cases, whereas air-containing cavities with communication to the middle and/or lower meatus and latent cysts were observed in 44.6% and 13.9%, respectively.
5. The location and the shape of the residual cavities on the asymptomatic side resembled those of the cysts on the symptomatic side.
6. Although the healing process of the postoperative maxillary cyst resembled basically that of the radical sinusotomy, scar tissue seemed to remain in the bony defect after cyst extirpation for a long time with much less tendency to bony fill or formation of air-containing cavities.
The results indicate that closure of the nasoantral window made beneath the inferior turbinate may be the main cause leading to the development of the postoperative maxillary cysts.抄録全体を表示PDF形式でダウンロード (18606K) -

ジャーナル フリーFrom July 1984 to September 1988, a total of 373 patients with HIV infection have been observed in the Department of Oral Surgery (North), Free University of Berlin. Oral manifestations in HIV infection are numerous and some of these have been acknowledged as being of great importance in the early diagnosis and prognosis of the disease. Oral manifestations in HIV infected individuals occurred as mycotic, bacterial or viral infection, neoplasms or manifestations of unknown etiology. Oral candidiasis occurring as pseudomembranous, hyperplastic and erythematous types should be considered. Oral hairy leukoplakia, pathognomonic for a HIV infection, has been considered to represent a probable diagnostic marker for the development of AIDS. HIV gingivitis and periodontitis are of particular significance.
Early and correct diagnosis of HIV-associated manifestations are important to the patient as well as the dentist who should install adequate protection measures.抄録全体を表示PDF形式でダウンロード (8032K) -

ジャーナル フリーIn the clinical and radiological findings from two cases of maxillary ameloblastoma treatment, it was found that the appearance of tumor were well contrast each other. One was an ameloblastoma in the right upper premolar region of a female aged 58. It was a solid tumor that developed into honeycomb structure. A radiograph of the tumor showed a mottled opaque pattern. The pathological examination revealed that this tumor was essentially a plexyform type, containing some dental lamina like constitution. It seems likely that the origin of the tumor was a dental lamina which failed to undergo degeneration.
The other case was an ameloblastoma in the left upper molar region of a male aged 34. The tumor was cystic and showed unilocular radiographic image. By pathological estimation, this tumor was classified as follicular type which resembled matured enamel organ. Thus it appears to have developed from a enamel organ.
Both cases have good prognosis and no recurrence after surgical treatment.
It may be inferred from these results that the remarkable difference of ameloblastoma are caused by the difference of the origin ; the initiation time of the tumor cell during the dental germ differentiation and the place where this occurred.抄録全体を表示PDF形式でダウンロード (22650K) -

1) Mean age of the series was 62.1 years. Of 42 cancer of the floor of the mouth cases, 39 were male and 3 were female.
2) Cases treated by irradiation (R) were 22, treated by irradiation and surgery (R+S) were 13, treated by surgery were 7.
3) Clinically, T2 and T3 cases and Stage 4 cases were most frequently encountered. The survival rate of high stage cases and advanced cases were lower than those of low stage ones and those of non-advanced ones. Endophytic growth type was related to poor prognosis.
4) Histologically, cases of moderately and well differentiated type were most frequently encountered. Cases of well differentiated type had good prognosis. Regarding the mode of cancer invasion, cases of type 3 (no distinct borderline) were most frequently encountered. Cases of type 4D (diffuse invasion) had poor prognosis.
5) The 5 year cumulative survival rate in each therapy was 54.5%(R), 53.9%(R+S), 100.0%(5), and the over all 5 year survival rate was 61.4%.抄録全体を表示PDF形式でダウンロード (1007K) -

ジャーナル フリーHistopathological diagnosis of non-Hodgkin's malignant lymphoma (NHL) is sometimes very difficult, especially in respect of the distinction from undifferentiated carcinoma.
The authors experienced a case of NHL that occurred at the right submandibular region. An incisional biopsy was performed for the definitive diagnosis, the histopathological finding was suspected as an undifferentiated carcinoma or NHL. It was difficult to discriminate NHL from an undifferentiated carcinoma. Therefore to distinguish them immunohistological examinations were attempted.
The specimen was not positively stained with the antibodies against S-100 protein and keratin. Keratin is a valuable marker for epithelial tumors, but undifferentiated carcinoma cells sometimes lack immunoreactivity for keratin.
Epithelial membrane antigen (EMA) is increased in the epithelial cells in a variety of diseases including many tumors. In our case, the tumor cells were negative for EMA, so it was thought that the tumor did not originate in the epithelial component.
Leukocyte common antigen (LCA) is a surface antigen of the lymphocytes, and NHL cells possess immunoreactivity for LCA. The tumor cells in our case were positive for LCA, and the tumor was finally diagnosed as NHL (diffuse, large cell type).
In conclusion, LCA and EMA are useful to the diagnostic discrimination between NHL and undifferentiated carcinoma.抄録全体を表示PDF形式でダウンロード (7412K) -

ジャーナル フリーEight oral cancer cases who were reconstructed by pedicled latissimus dorsi myocutaneous flap following excision of tumors in our department were assessed retrospectively. Of these cases, 2 were untreated advanced cancers and others were recurrent or treated in other hospitals previously, 3 tongues, 2 buccal mucosas, 1 floor of the mouth, 1 maxilla and 1 neck. Depending on these primary sites, all cases were squamous cell carcinomas histopathologically. 4 cases were reconstructed by combination with other major flaps such delto-pectoral flap, trapezius myocutaneous flap, pectoral major myocutaneous flap and iliac osteomyocutaneous free flap for both oral and extra-oral defects simultaneously. The maximum size of the skin paddle was 22×10 cm. No necrosis in 5 cases (5/8), partial necrosis in 2 cases and total necrosis in one case were fallen, and 2 recurrences happened postoperatively. This kind of flap is very useful from the cosmetic view point for females, being able to obtain the largest size of skin paddle among all pedicled type of flaps for the head and neck region and possible to combine with other major flaps if necessary.抄録全体を表示PDF形式でダウンロード (9626K) -

ジャーナル フリーAn odontoma is defined as odontogenic tumor composed of hard tooth-like tissues such as enamel, dentine and cementum in varying proportions and states of development.
In the present paper, a case of complex odontoma with findings by electron probe microanalyser was reported and 21 cases of odontoma from our Department for 10 years were reviewed.
A 23-year-old female was referred to our clinic because of swelling of over 10 months duration on the right buccal region. Intraoral examination disclosed a diffuse swelling of upper right molar region. The region was of bone-like hardness and the overlying mucosa was partially ulcerated. Radiographically, there was a well-circumscribed, large radiopaque area in the right retromolar region of the maxilla. A clinical diagnosis of odontoma was made.
The patient was admitted and surgical removal of the tumor was performed under general anesthesia. The postoperative course was uneventful.
The resected tumor bony-hard in consistency was 2.3 by 2.3 by 3.3 cm in size, 13 g in weight and yellow in color. Microscopically, the tumor consisted of mass of irregularly arranged enamel, dentine, cementum and fibrous connective tissue. Histopathological diagnosis of this tumor was complex odontoma.抄録全体を表示PDF形式でダウンロード (7035K) -

ジャーナル フリーRecently a considerable number of surgical treatments have been published, although conservative treatments to relax the muscle tone are scarce.
A case of habitual luxation of the temporomandibular joint caused by uncorrected denture was experienced. A 68-year-old woman had a low vertical dimension denture and occlusal disturbance. She experienced luxation with moderate mouth opening several times in a day.
Though she had a steep anterior surface of articular eminence as a constitutional factor, conservative treatment, splint therapy, was effective.
This report suggested that habitual luxation of the temporomandibular joint, in this case, is mainly based on muscle incoordination of occlusal origin.抄録全体を表示PDF形式でダウンロード (5052K) -

ジャーナル フリーEosinophilic granuloma of the soft tissue (eosinophilic lymphoid granuloma) is a benign chronic disease. The characteristic features of this disease are the swelling of the subcutaneous soft tissue, the increase of eosinophils in the peripheral blood, and histlogically, the formation of lymphfollicular and the infiltration with eosinophils.
We reported a 38-year-old man who had an eosinophilic granuloma of the soft tissue (eosinophilic lymphoid granuloma) in the bilateral parotid gland regions. This patient was treated by irradiation of 60Co in the total dosage of 30Gy and the electric beam in the total dosage of 10.5Gy. Radiation therapy effectively reduced the swelling and the eosinophils count.

ジャーナル フリーThe authors report a case of plunging ranula with cumulative cases of ranula which had been treated in our department from January 1983 to December 1988. The patient, a 27-year-old male, had been aware of a swelling in the left submandibular region for the preceeding several months. At the first visit to us, the face of the patient was asymmetrical with a diffuse swelling from left submandibular to mental regions. The overlying skin of the lesion was normal in color, and palpation gave us an impression of existence of a soft mass with fluctuation. Fine-needle aspiration prior to the surgery yielded 3 ml of yellowish mucinous material. Sialography on lateral view and ultrasonography disclosed a cystic mass with lobulation and regular margin in the left submandibular region. The computed tomography revealed a radiolucent mass at the sublingual region in contact with ipsilateral sublingual and submandibular glands. The patient was operated on with a clinical diagnosis of plunging ranula on October 21, 1988. During the operation, blunt dissection was performed between the fibers of the mylohyoid muscle toward the sublingual and submandibular glands. Consequently the ranula was extirpated with the ipsilateral sublingual and submandibular glands. Postoperative course, about four months after the operation, was uneventful without recurrence. Consequently the ranula was extirpated with the ipsilateral sublingual and submandibular glands.
Our 52 cumulative cases including the present one were 83% sublingual type, 15% sublingual-submandibular type and 2% plunging type. Distribution of age of the patients had two peaks in the first to third decades, and at the fifth decade. The occurrence of plunging type of ranula was assumed to be low and rare from our review of the literature and evaluation of our cumulative cases. Marsupialization should be performed for the treatment of sublingual and sublingual-submandibular types of ranula, whereas dissection of the lesion with involved salivary gland for the plunging type and the recurrent case. W hile it is difficult to differentiate the plunging entity from the sublingual-submandibular ranula, the precise diagnosis should be taken from sialography, computed tomography, ultrasonography, and characteristics of the constituents.抄録全体を表示PDF形式でダウンロード (7591K) -

ジャーナル フリーDuring the past 22 years, there has been an increase of patients with severe skeletal malocclusion were cared orthodontically, before and/or after surgical correction. The purpose of this study was in point of examination of the basic concept of the treatment for these cases through clinico-statistical observation. Several conclusions were as follows:
1. During the last decade, the number of patients have remarkably increased.
2. Most cases of morphological abnormality before operation were diagnosed as severe mandibular protrusion, except a case of mandibular micrognathia caused by injury.
3. Most surgical corrections carried out between 16-20 years of age and after the adoles-cent-growth spurt.
4. The operating method has gradually changed from Kosteeka's method to the osteotomy of the mandibular body, and then to the sagittal splitting osteotomy. In recent years, the Obwegeser-Dal Pont method, and Hunsuck modification were carried out.
5. Intermaxillary wiring fixation was released for 2-3 weeks after operation. However, to obtain good adjustment of post-operative occlusion, intermaxillary elastics were used after wiring fixation.
6. Orthodontic treatment to obtain the harmonious and stable balance between bone structure and muscle function should be performed at least for 6-12 months after operation.抄録全体を表示PDF形式でダウンロード (2292K) -

ジャーナル フリーThis study evaluated the clinical effect of Fungizone syrup (Amphotericin B) administered as gargle to 49 oral candidiasis, patients referred to our department from December 1984 to February 1988. Out of 49 patients, 31 had malignant tumor and 2 had diabetes mellitus, 13 were administered steroidhormone, 12 had anti-tumor drug and 6 had antibiotics, and 14 used prosthetics. The candidiasis locations were tongue (33 patients), buccal mucosa (14), palate (14), gingiva (7), mucosa of lips (5) and angle of mouth (1). Fungizone syrup solution diluted in 4 × 103 fold and 102 fold were used respectively for 34 patients and 15 patients. Clinical effect of Fungizone syrup in 4 × 103 fold diluted group were excellent in 9 cases, good in 22 and poor in 3, but 102 fold diluted group were excellent in 13 and good in 2. Significant differences between the two groups were observed (p<0.001). In conclusion, gargle of Fungizone syrup was effective with oral candidiasis, especially in the 102 fold diluted group.抄録全体を表示PDF形式でダウンロード (828K) -

ジャーナル フリーAnodontia is a rare disease caused by heredity, ectodermal dysplasia, phylogenetic degeneration, damage to the mother's womb during the prenatal stage and acquired general disease. This disease is occasionaly accompanied with malocclusion and gnathal hypoplasia, however, only prosthetic treatment has been performed in general.
We recently performed on operation to ship the mandible inferoposteriory using a sagittal splitting technique followed by a prosthetic wearing at a newly established jaw level in 13-yearsold male patient with anodontia complicated with deep overbite, reversed occlusion and bite. A favorable result was obtaind through this technique.抄録全体を表示PDF形式でダウンロード (4346K)
