Traumatic occlusion is a morbid condition that is caused by repeated occlusal stresses exerted on the periodontium that exceed the physiologic limits of tissue tolerance and contribute to the breakdown of the supporting tissue of the teeth. In reviewing these cases, the authors obtained the following results. 1. Roentgenographic examination revealed the typical signs of traumatic occlusion: severe resorption of roots, destruction of alveolar bone. 2. The major factor of traumatic occlusion is abnormal occlusal force. 3. The rsorptions of roots and periodontal changes which are caused by traumatic occlusion depend on the individual variation of the physical potential. 4. The pathologic features of traumatism are basically different from those of inflammation.

A 54-year-old male patient was admitted due to dyspnea with chest pain and reddish swelling in the right lteral neck and right upper which developed 2 or 3 days age. He was treated with acupuncture in the neck about one week ago prior to admission. CT scans of the chest showed density of air and abnormal soft tissue which suggested abscess of the anterior mediastinum and subcutaneous tissue. He underwent cervical and mediastinal drainage with closed thoracostomy and antibiotic therapy. Black-pigmente anaerobic nonspore-forming gram-negative bacilli were isolated from the mediastinal pus and were identified as Prevotella intermedia/nigrescens upon performing biochemical tests and API rapid ID 32A (bioMeriux, France) kit. He underwent decortication of the right side because of loculated empyema on 41st postoperative day. He was fully recovered and discharged on the 82nd hospital day. This was thought to be another case of descending necrotizing mediastinitis not caused by peritonsilar abscess but by cellulitis developed after acupuncture. Early deterction of mediastinits and aggressive drainage of mediastinal abscess are important.

The purpose of the current study was to evaluate the effect of the zinc-deficient diet on the connectine tissue of oral mucosa in the albino rats. The zinc dificient diets were supplied to the rats for 4 weeks. The results were as follows: Most of the papillas of lamina prmina propria were shortened. The abnormal distribution and orientation of the fibrous elements were observed. The stain ability of fihrous elements in the Mallory azan stain was decreased. The amorphous intercellular substance showed slight metachromasia in the toluichine blue stain and low PAS reactinity.

Congenital anomalies occur at low levels in Korean antive cattle. PCR and Serum neutrlizing test against BVD, Akabane virus, Ibaraki virus, Kasba virus were examined. The results were all negative. Gross anatomical analysis was carried aout. Congenital abnormal newborn calf had 2 atropic left hindlimbs, which was nor moved autonomosly. The length of 2 atropic hindlimbs was 72 em and 48cm respectively. Both of them were curved severely at joints. Affected limbs were developed in connective tissue but lack of muscular tissue. In the abdominal region right kidney was normal. But there were two left kidneys which was half size compared with normal kidney. One of them had polycysts. In skeletal region, affected left limb is defective of head of femur and tibia.

Lymphangioleiomyomatosis(LAM) is defined as an abnormal proliferation of smooth muscles in the lung tissue throughout lymphatics, vascular and bronchial structure. A 52-year-old postmenopausal woman was admitted to our hospital for recurrent pneumothorax. She was treated for medroxyprogesterone by LAM 1 month ago. We performed operation of pulmonary partial resection and pleurodesis. The patient is receiving continuous medroxyprogesterone and Leuplin administration, and currently, 6 months after the operation, is still showing good results.

This study deals with the computing the temperature change of surface to the increment of time and diffusivity, the heat flux during irradiation of laser. In addition, the computer algorithm for computing the penetration change of the corresponding surface irradiated is developed. The result of this study shows the possibility to treatment of cancer, abnormal cell and biological tissue during irradiation of laser.

The oxygen distribution at steady state is analyzed mathematically in a hexagonal cylinder. The domain is penetrated by parallel cylindrical capillaries of different oxygen squirt. Asymptotic solution is used to determine the effect of axial diffusion. Oxygen concentration profiles are displayed at some positions of capillary-beds. At the venous end some tissue areas suffer from a shortage of oxygen.

Many references report that abnormal diastema except temporary diastema existing in mixed dentition period is caused by maxilary heavy labial frenum, malocclusion, progressive periodontal disease, and loss of posterior teeth. We can diagnose patient as diastema caused by periodontal disease, especially, in case of accompanying progressively destructed anterior maxillary alveolar bone defect, and interseptal bone defect. We report Multiple disciplinary approach for diastema associated with periodontal disease. Periodontal treatment(Guided Tissue -Regeneration, alveoloplasty, bone graft), or thodontic treatment (space closure, redistribution), and the final proshodontic restoration for retention were used.

Background Preoperative computed tomography angiography (CTA) of the abdominal wall vessels is used when planning free flap breast reconstruction (FFBR) because it provides a surgical road map which facilitates flap harvest. However, there are few reports on the effect of abnormal findings on the operative plan. Methods We conducted a retrospective study of all FFBRs performed at a tertiary referral center over a 6-year period (November 2011 to June 2017). One consultant radiologist reported on the findings. Details on patient demographics, CTA reports, and intraoperative details were collected. Results Two hundred patients received preoperative CTAs. Fourteen percent of patients (n=28) had abnormal findings. Of these findings, 18% were vascular anomalies; 36% tumorrelated and 46% were "miscellaneous." In four patients, findings subsequently prevented surgery; they comprised a mesenteric artery aneurysm, absent deep inferior epigastric (DIE) vessels, bilateral occluded DIE arteries, and significant bone metastases. Another patient had no suitable vessels for a free flap and the surgical plan converted to a pedicled transverse rectus abdominis musculocutaneous flap. The remaining incidental findings had no impact on the surgical plan or appropriateness of FFBR. More than one in 10 of those with abnormal findings went on to have further imaging before their operation. Conclusions CTA in FFBR can have a wider impact than facilitating surgical planning and reducing operative times. Incidental findings can influence the surgical plan, and in some instances, avoid doomed-to-fail and unsafe surgery. It is therefore important that these scans are reported by an experienced radiologist.

Purpose: Diabetic foot ulcers are closely related to body surface heat, which can be affected easily by temperature differences. This study examined the correlation between the healing process of diabetic wounds and abnormal diurnal temperature through an animal study. Materials and Methods: Rats in the abnormal diurnal temperature group and control group were given a 10 mm sized full-thickness skin ulcer. Wound size progression was observed in both groups. H&E and Masson's trichrome staining was performed at 14 days after wound formation, and the number of vessels per unit area and histology analysis were performed. The changes in the ulcer were measured through three dimensional cross-section area using INSIGHT^® devices. Results: The wound recovery period (granulation ingrowing) was 24 days in the abnormal diurnal temperature model and 20 days in the control group. The thickness of scar tissue was 402±23.19 ㎛ in the control group and 424.5±36.94 ㎛ in the diurnal temperature model. Neovascular formation was counted as 5.1±0.97 for the control group and 4.16±0.94 for the diurnal temperature model group. Conclusion: Delayed and inferior diabetic wound healing was observed in the abnormal diurnal temperature group, which was characterized by greater diurnal variations than the typical growth environment.
