ジャーナル フリーChanges in vascularization on the articular disk of temporomandibular joint (TMJ) under the condition of unilateral mastication in rats were observed.
Forty 8-week-old male Wistar rats were used. In 20 rats, the right upper 3 molar teeth were extracted and the right upper incisal was amputated at the gingival margin. The other 20 rats were served as controls. After 4 months, the rats were killed and the articular disks of TMJ were dissected carefully. After fixation in 10% formaldehyde, the specimens were embedded in paraffin, and 20μ thick serial sections were cut along the longitudinal axis of the articular disk. After Peroxidase staining according to the Graham-Karnovsky method and staining with Methyl green, the specimen weres observed microscopically. The following findings were obtained;
1. In 9 rats of the experimental group, vascularization was found.
2. Vascularization was found on the articular disks of TMJ of both the operated and the unoperated side.抄録全体を表示PDF形式でダウンロード (7938K) -

ジャーナル フリーThe present study was attempted to elucidate histochemical characteristics of destruction and regeneration of skeletal muscle fibers with injection of a local anesthetic drug.
After single injection of 0.3 ml of 0.5% bupivacaine hydrochloride (BH) into the rat masseter, soleus and gastrocunemius muscles, the animals were killed at 1, 3, 5, 7, 14, 21 and 28 days. Fresh frozen sections fixed with isopentane into liquid nitrogen were made at 10 μm in -20°C cryostat for myosin ATPase, SDH, AchE and laminin. The others were fixed with 2% glutaraldehyde and embedded in EPON 812 for electronmicroscopy. The skeletal muscle fibers were classified into 4 types (I, II A, II B and II C) according to Brooke and Kaiser's procedure with myosin ATPase with acid and alkaline pre-incubation.
At 1 and 3 days following BH injection, affected muscle fibers showed plasma membrane degeneration, but remaining basal lamina and AchE activity in synaptic junction were detected to be without degeneration. After 5 days, satellite cells grew in numbers at the basal lamina of muscle fibers, and from 7 to 14 days, extensive regeneration of muscle fibers appeared. Immunohistochemically detectable laminin staining clearly existed in the basal lamina in those degenerated and regenerated muscle fibers. Degenerated muscle fibers of the 7 days specimens generally showed 11 C type fibers and strong SDH activity. In 14 to 28 days after BH injection, type II C fibers transformed into either type I, II A or II B fibers.抄録全体を表示PDF形式でダウンロード (26750K) -

ジャーナル フリーMetals and ceramics e.g., stainless steel, titanium (Ti) or its alloys, aluminium oxide, hydroxyapatite, and so on have been used as biomaterials in the fields of oral surgery and orthopedics. Many studies for their biocompatibility and clinical usage have evaluated their merits or demerits. The present study has focussed actention on an evaluation of precious metals, especially gold (Au) and platinum (Pt) for dental implants.
Materials: Au-Pt alloys (Au weight %: 5, 20, 30, 40, 50, 60, 70, 80, 90, 95), Au (99. 99%) and Pt (99. 99%) were examined, and Ti (99. 5%) as a control. Methods: 1. Hardness test of Au-Pt alloy (Hv). 2. Cytotoxicity test used cultured cells. 3. Quantification of dissolved Au and Pt ions. 4. In vivo study used dogs for histopathology and immunohistochemistry. Results: From the point of mechanical function, Au-Pt alloys (5-80 Au weight %) suggested that they could be used as dental implants. Cytotoxicity of the Au-Pt alloy and Ti was no problem. Dissolved Au, Pt and Ti ions disappeared (<0.01 ppm). The Au-Pt alloys indicated excellent biocompatibility as well as Ti as materials for dental implants.抄録全体を表示PDF形式でダウンロード (12395K) -

ジャーナル フリーA case of temporomandibular joint (TMJ) dysfunction which occurred in a 58 year old woman was reported. The patient was referred to our clinic with complaints of limitaion of jaw opening and of pain in the right masseteric region. No improvements of the symptoms were obtained by ordinary occlusion therapies for TMJ dysfunction.
Spontaneous closing movements and rigidity in the masticatory muscles during the resting position led to suspicion of a neurologic disease as a cause of her TMJ dysfunction.
Administration of Sulpiride (antidopaminergic drug) by the initial diagnosis of oral dyskinesia made the situation worse. On the contrary, Trihexyphenidyl (anticholinergic drug: anti-parkinsonism drug) was of much benefit in improving the symptoms and curing the TMJ dysfunction after short-period administration. Because of the remarkable effects of this drug, her TMJ dysfunction was considered to be caused by a parkinsonism-like disease localizing in oro-facial region together with other local factors.抄録全体を表示PDF形式でダウンロード (3763K) -

ジャーナル フリーA 75-year-old malewith a primordial cyst containing Rushton's hyaline bodies is reported. Radiography revealed an oval, radiolucent mass in the alveolar part of 1'12 region. Small radiopaque substances were present in part of this bone radiolucent figure. Cystectomy was performed under a clinical diagnosis of calcifying odontogenic eyst. Histopathological findingsrevealed that the cystic wall consisted of three to eight squamous epithelial layers and connective tissue. Hyalin bodies were found in the thick layer of the epithelium and on its surface. Granular material was often seen in the central portion of some hyaline bodies, and most of them showed calcification. The histopathological diagnosis was a primodial cyst containing hyalin bodies. Dental cuticles of the inpacted tooth were compared with hyaline bodies by histochemical staining. The inner zone of dental cuticles showed stainability similar to hyaline bodies.抄録全体を表示PDF形式でダウンロード (8322K) -

ジャーナル フリーTwo interesting epulis, a congenital epulis (granular cell tumor) and extremely enlarged ossifying epulis were reported.
The first case was a congenital epulis found in a newborn. Firm, slightly reddish mass (18×11×10 mm) had formed on the lower gums. The lump-shaped tumor was extirpated under the diagnosis of congenital epulis. The histopathologic findings revealed typical features of granular cell tumor composed of large polygonal cells possessing eosinophilic cytoplasmic granules and polarized nuclei. Immunohistochemically, proteins such as carcinoembriogenic antigen, a-fetoprotein, vimentin, desmin, lysozyme and keratins were fully negative but positive for S-100 protein stain. From the results above, this tumor was mostly suspected to be neurogcnic in its origin.
The second case was a extremely giant ossifying epulis. A peclunculted large and strongly firm, slowly growing painless tumor was found on the left side of the upper jaw of a 33-year female. The hard tumor had enlarged beyond the teeth to reach the median line on the palate. The extirpated tumor was composed of proliferating dense fibrous tissue and abundant ossifying spicules with mild cell infiltration. Fibroblasts seemed young with large hyperchromatic nuclei, but no osteo-blast could be observed. The histopathologic features indicated that osteofibrous epulis a type of ossifying epulis, was most suitable for this tumor.
Adding with the report of two cases above, some clinical and histopathologic characteristics of epulis were discussed with guidance of the published studies.抄録全体を表示PDF形式でダウンロード (8165K) -

ジャーナル フリーLymphoepithelial cysts are often found in the lateral cervical region and rarely within the parotid gland.
The patient, α 31-year-old female, complained of a mass in her right parotid gland. On physical examination, a tumor about 2 × 1 cm in size was palpable and the preoperative impression was a benign parotid gland tumor.
Under general anesthesia, the tumor was resected by superficial parotidectomy, and the exposed facial nerve was covered with a sternomastoid muscular flap to prevent Frey syndrome, which often occurs after this kind of operation.
On pathological examination, the tumor was found to be a lymphoepithelial cyst lined with stratified squamous epithelium with abundant lymphoid tissue beneath the epithelium.
We suggest that the cyst may be arose from the ectopic salivary gland tissue in the lymph node within the salivary gland.抄録全体を表示PDF形式でダウンロード (9009K) -

ジャーナル フリーWe reported the clinicopathological features of primary malignant melanoma of the oral cavity in the Part I and II. In this Part, we studied 20 cases of benign and premalignant pigmented lesion in the oral mucosa. The 20 cases consisted of 1 premalignant and 19 benign (4 pigmented nevi, 12 non-nevoid melanocytic lesions, and 3 others) lesions.
Pigmented nevus was divided into three types; junctional, compound and intramucosal nevus. Non-nevoid melanocytic lesion showed various degree of proliferation of dendritic or clear cell-like melanocytes, hyperpigmentation in the basal cell layer, and phagocytosis of melanin in the connective tissue.
One case of premalignant melanocytic lesion occurring in the lower lip had two phases; the plaque and the macular lesions. The plaque lesion revealed proliferation of atypical melanocytes and small nest formation along the basal cell layer. The macular lesion consisted of mild proliferation of melanocytes having no cellular atypia, and hyperpigmentation in the basal cell layer. According to these findings, the lesion was considered to be precursor of ALM.
Precursor lesion of oral malignant melanoma has not been well documented. We discussed here the potential of malignant transformation of pigmented nevus and non-nevoid melanocytic lesion of the oral mucosa.抄録全体を表示PDF形式でダウンロード (15620K) -

ジャーナル フリーA 35-year-old woman presented a rapidly growing anaplastic carcinoma of the left maxilla after a history of radical operation of maxillary sinus. Marked leukocytosis was also observed in this patient in spite of no evidence of infection, and high CSF (Colony Stimulating Factor) activity was demonstrated in the patient's serum.
The lesion was treated by irradiation and chemotherapy, but the patient finally died of matastatic lung tumor after 10 months.
The histologically features of this carcinoma were pleomorphic appearance consisting of severely atypical giant cells that resembled that of giant cell carcinoma of the lung or thyroid.
We recognized that this case was a rare anaplastic carcinoma with CSF producing ability.抄録全体を表示PDF形式でダウンロード (7048K) -

ジャーナル フリーRanula, which is mucocele originated from greater and lesser salivary glands of the oral floor region, presents unilateral swelling of this region as main symptom, but occasionally extends beyond mylophyoid muscle to the mental and submandibular parts of the oral region, where its swelling is developed. Although it is called plunging ranula in view of its site of onset, it rarely developes primarily from the submandibular part.
We report here a personal case of plunging ranula developed primarily in the above part of a 3-year-old girl, together with some additional considerations.
1) During the past 20 years in this country, as far as infants aged below 5 years are concerned, only 4 cases were reported to have presented primary symptoms of ranula in the submandibular part.
2) The involvement of the age in the pathogenesis of plunging ranula seemed to be undeniable.
3) The aminoacid analysis of the protein in the intracystic fluid seemed to leave room for further examination.
4) Good results were obtained by both extirpation of sublingual gland and cystectomy. Some additional considerations were made from the angles of this experience of ours and the literature.抄録全体を表示PDF形式でダウンロード (8333K) -

ジャーナル フリーTrichoepithelioma, either solitary or multiple, is a small benign tumor containing multiple horn cysts simulating to a varying degree abortive pilar structures. Multiple lesions are usually hereditary and appear mainly on the face. Solitary lesions are not inherited, but also commonly appear on the face. The multiple and solitary trichoepitheliomas are histologically similar, and their differences are basically clinical.
We experienced a very rare case of solitary trichoepithelioma of the upper lip in a 44 year old male. Microscopically, the tumor was composed of numerous islands of basaloid cells intermingled with horn cysts.
The present trichoepithelioma in its structure was histologically different from trichofolliculoma and basal cell carcinoma.抄録全体を表示PDF形式でダウンロード (6175K) -

ジャーナル フリーA case of mandibular reconstruction with clavicle is presented. A 54-year old woman, who received irradiation for therapy of buccal cancer, visited our clinic complaining of exposed bone at premolar area. This lesion has become oro-cutaneous fistula with bone necrosis within a few years in spite of minor sequestrectomies. Necrosed mandibular body was, therefore, resected about 5 cm in length. Seven months after this treatment, splitthickness of clavicle was used with sternocleidomastoid muscle as an osteomascular flap. Skin graft vestibuloplasty was done one year after success of mandibular reconstruction. Denture is well-fitted and stable on improved alveolar rigde.抄録全体を表示PDF形式でダウンロード (11661K) -

ジャーナル フリーAs the aged population increases general complications of patients with head and neck cancer have increased. Then previous and present general illnesses of the patient should be carefully noted and decisions on his best therapies should be done.
This paper describes a case of gingival cancer with heart and lung complications, and postoperative transient myocardial ischemia from the aspect of patient management.
The patient was a 72-year-old male with gingival cancer of the mandible (T1N0M0) who suffered from pulmonary fibrosis, secondary pneumonia and a complete left bundle branch block (LBBB). The patient was treated with radical surgery under general anesthesia (GOF) and tolerated the procedure well, and subsequently was sent to the ICU, though he was in satisfactory condition.
He did not complain of dyspnea and chest pain ST segment depression and negative T wave were caused by nasopharyngeal pain of the feeding tube, by coughing, and by changes of body positions in the early postoperative period. Laboratory examinations, such as CK and LDH isoenzymes showed normal valves. On the eleventh day negative T wave returned to normal. These findings suggested transient myocardial ischemia. Ambulatory electrocardiographic and echocardiographic observations revealed no underlying cause of transient myocardial ischemia and LBBB.
Further severe pulmonary complication after surgery had been prevented by urged expectoration, sustained maximum inspiration, subseqent oxygen therapy, control of pain and medicaticn of antibiotics.抄録全体を表示PDF形式でダウンロード (4646K) -

ジャーナル フリーTwo cases of verruciform xanthoma are reported with the review of 39 cases in domestic literature. Case 1, a 48-year-old female had a slightly elevated yellowish lesion on lingual aspect of mandibular left premolar-molar gingiva. Case 2, a 40-year-old female had a crescent shaped yellowish area on the gingiva buccal to the mandibular left first molar. Both were uneventful after simple surgical excision. Histologically, pebbly surface was covered by parakeratotic squamous epithelium. Characteristic accumulation of lipid laden foam cells were identified in connective tissue papillae between equally elongated rate pegs to a uniform depth. Especially in case 1, examination with the serial sections revealed gradual transformation to papillary architecture of the squamous epithelium in peripheral portion.
The cause of verruciform xanthoma is still uncertain, but mild chronic inflammatory irritation may play the important role of its genesis.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Myxoma is a. comparatively rare disease occurring in jaw bone. We encountered a 17-year-old girl who developed odontogenic myxoma from the region of the right lower second premolar to the right mandibular ramus.
The patient appeared at our department with gingival swelling at the right lower molar region.
Biopsy revealed histopathological evidence of odontogenic epithelium and myxomatous tissue.
The lesion was managed by mandibulectomy under general anesthesia, immediately followed by reconstruction using A-O reconstruction plate and iliac bone autograft. This surgical intervention was satisfactory. No recurrence was found 4 years after surgery. Ninety-eight cases of myxoma of the jaw reported in literature were reviewed and the present case was comparatively discussed.抄録全体を表示PDF形式でダウンロード (10055K) -

ジャーナル フリーFor prevention of infection and antiinflammatory and antalgic treatment after tooth extraction, enoxacin and fenbufen were given together to a patient, who then showed side effects of critical symptoms.
The side effects appeared after the second administration of the drugs, and were severe chronic convulsion and severe disturbance of consciousness. Diazepam was given as convulsion treatment, simultaneously with transfusion of a large amount of fluid containing diuretics for quick disintoxication and elimination. About 24 hours after appearance of the side effects, convulsion disappeared, and after 3 days disturbance of consciousness also disappeared. In laboratory examination, the peaks of GOT (546 KU) and GPT (251 KU) were found on the 3rd to the 5th days, and CPK and LDH became very high on the 3rd to 4th days.(CPK: 46, 575 IU, LDH: 1, 496 IU) In the isozyme analysis, strong spots appeared at LDH (V) and CPK (MM). On the 4th day the urinalysis revealed high occult blood reaction, but it would be due to the existence of a large amount of myoglobin in urine. The above-described test results suggested severe fatigue of skeletal muscles due to convulsion. In electroencepharography, slow waves were prominent 3 days after disappearance of convulsion, and then spikes were often seen.
The side effects will be caused by such a mechanism that fenbufen depresses the renal function to elevate the blood concentration of enoxacin, which results in exhibition of its specific activity to the central nervous system.抄録全体を表示PDF形式でダウンロード (3227K) -

ジャーナル フリーDevelopment of osteosynthesis materials has contributed to the remarkable advancement of the treatment of mandibular fracture and reconstruction of the mandible. Especially, dynamic compression osteosynthesis techniques including the A-O system has transformed the conventional concept of reconstructive treatment.
However, since stainless steel is used in the A-O system, there has been a problem in the biological affinity of A-O material for tissues. Development of a mandibular reconstruction plate using a metal such as titanium that has a tissue affinity has been strongly awaited. In fact, titanium has high anti-corrosive property and does not induce foreign body rejection. Furthermore, it is characterized by the advantage of being retained for a long time in living human body. Only a titanium miniplate has been available so far as reconstruction material made of titanium. It has been found that even though this plate is used for mandibular reconstruction after continuous resection or unilateral resection of the mandible which entail a somewhat large interspace, the deficiency of the structural rigidity could cause displacement of the graft and hence could result in infection.
Our recent attempt at mandibular reconstruction in 4 patients using the titanium mandibular reconstruction system proposed by Reuther et al. of Warzburg University(WTMR) have produced successful results.
The patients to whom WTMR was applied consisted of 1 who underwent immediately reconstruction after continuous resection of the mandible due to mucoepidermoid carcinoma, 2 who underwent continuous resection of the mandible due to odontogenic keratocysts and 1 who underwent fixation and reinforcement of the pathologically fractured mandible due to abnomral resorption of the mandible. In the patients treated for reconstruction, satisfactory continuity and symmetricity were restored. In the patient treated for fixation, the fractured bone was joined satisfactorily.抄録全体を表示PDF形式でダウンロード (10570K) -

The questionnaires were returned from 303 patients and 112 (37.0%) reported no symptoms. Corelation between long-term results and each factor was investigated, the following results were disclosed: There is no significant difference between male and female. The asymptomatic ratio of patients over 60 years old was comparatively high. Duration of symptoms before treatment and the symptoms at the first visit were significant in this group. For example, many patiens who had visited the clinic within one month from onset of this disease reported no symptoms. On the other hand, the percentage of asymptomatic patients who had TMJ noise at the first visit was low. There is a significant difference of asymptomatic percentage between patients who had received medication alone and patients received medication in combination with other conservative treatment. The many patients who had visited more than 10 times complained of persistent symptoms.
TMJ noise and trismus were the most common findings as residual and persistent symptoms at this examination. Furthermore, after completion of initial treatment, some patients reported having symptoms at this examination. These findings indicated the need of long-term follow up of patients with TMJ arthrosis.抄録全体を表示PDF形式でダウンロード (1343K) -

ジャーナル フリーBy measurement of parameters such as body weight, circumferentiallength of theupper arm, blood plasma proteins of total protein(TP), albumin(Alb), cholinesterase(ChE) and rapid turn over proteins of transfection(Tf), prealbumin(PA) and retinol-binding protein(RBP), nutritional conditions were assessed in 31 oral disease patients who received an elemental diet(Elental®) after maxillo-facial surgery. The results were as follows: both body weight and circumferential length of upper arm muscles did not exactly reflect the nutritional condition while PA and RBP decreased immediately after the surgery to near 80% of the preoperative values, and recovered within a week from the decreasement. Decreases in Tf, Tp, Alb and ChE were not so significant. Compared with rapid turn-over of proteins, TP, Alb and ChE varied slowly. From these, it seemed that PA and RBP were more utilizable for the follow-up of rapid changes in the nutritional condition, and proteins such as TP, Alb and ChE were likely as useful for more static natritional assessment. From the fact that 2 weeks after the operation, all rapid turn-over proteins increased to about 115% of the original level.
It seemed likely that administrated Elemental played an advantageous role in supporting good nutritional condition抄録全体を表示PDF形式でダウンロード (1058K)
