Belt injury is an increasingly serious injury and one that frequently results in undesirable disabilities. We reviewed 20 cases of belt injury which had been treated in Kyungpook National University Hospital during the five and a half year period from Auguat, 1972 to January, 1978. 1. This injury is more prevalent in males (M:F = 4:1) with the peak incidence between the second and fourth decades (85%). 2. Upper extremities are involved in almost all cases (95%). 3. Some injury patterns were more frequently seen and were classified arbitarily as follows: Type I

Tuberculous tenosynovitis affecting flexor tendon sheaths of the hand is a rare condition and quite disabling to the patient like tuberculosis elsewhere. It should be attacked by operation and antituberculous chemotherapy, but has a tendency to recur after surgery. The authors have encountered a case of tuberculous tenosynovitis affecting flexor tendon sheaths in the palmar area of the left hand, and treated the case with surgery and anti-tuberculous chemotherapy.

3.Expression Pattern of Immunoproteasome Subunits in Human Thymus.
Immune Network 2009;9(6):285-288
The expression pattern of immunoproteasomes in human thymus has not been analyzed but may have important consequences during thymic selection. Here we examined the expression patterns of immunoproteasome subunits in fetal and adult thymic tissues by immunohistochemistry and found that all three subunits are expressed in both cortical and medullary stromal cells. These data suggest that thymic selection in human can be affected by peptide repertoires generated by immunoproteasomes.

Clinical study was done on 119 patients with atrial fibrillation in the aspect of underlying diseases, particulary. The results were as follow : 1) In the underlying diseases of atrial finbrillation, rheumatic heart disease, hepertension and ischemic heart disease were common, which occupied 27.8%, 22.7% and and 15.1%, respectly. No apparent underlying disease was found in 21.0%, but in the transient atrial fibrillation, no apparent underlying disease in 42.9%. 2) There were no significant correlations between the ventricular rate, amplitude of f wave and underlying diseases of atrial fibrillation. 3) Complications were found in 29.4% of all cases, such as congestive heart failure(22.7%), embolism(6.7%). Otherwise, atrial fibrillation without underying cardiovascular diseases, congestive heart failure was found only(7.7%).

Generally, if the size of a lip cancer defect exceeds 30% of the lower lip, a local flap or free flap is recommended. However, defects up to 50% of the lower lip in size have been reconstructed successfully by primary closure without a local flap or free flap. In one case, an 80-year-old male farmer who had smoked for more than 50 years presented with squamous cell carcinoma of the lower lip and underwent mass resection and supraomohyoid neck dissection. The defect accounted for almost 2/3 of the lower lip and was repaired by primary closure with V-shaped resection. Biopsy results confirmed pT2N0cM0 stage II disease with clear margins. In another case, a 68-year-old male also presented with squamous cell carcinoma of the lower lip and underwent mass resection. The defect accounted for about half the size of the lower lip but was repaired by primary closure with V-shaped resection.Both patients experienced no discomfort while eating or speaking and were satisfied with the cosmetic and functional outcomes with no evidence of recurrence. Thus, direct closure can be considered even in large lower lip cancers.

Purpose:
This study aimed to evaluate the clinical usefulness of magnetic resonance (MR) neurography using the 3-dimensional double-echo steady-state with water excitation (3D-DESS-WE) sequence for the preoperative delineation of the facial and lingual nerves.
Materials and Methods:
Patients underwent MR neurography for a tumor in the parotid gland area or lingual neuropathy from January 2020 to December 2021 were reviewed. Preoperative MR neurography using the 3D-DESS-WE sequence was evaluated. The visibility of the facial nerve and lingual nerve was scored on a 5-point scale, with poor visibility as 1 point and excellent as 5 points. The facial nerve course relative to the tumor wasidentified as superficial, deep, or encased. This was compared to the actual nerve course identified during surgery. The operative findings in lingual nerve surgery were also described.
Results:
Ten patients with parotid tumors and 3 patients with lingual neuropathy were included. Among 10 parotid tumor patients, 8 were diagnosed with benign tumors and 2 with malignant tumors. The median facial nerve visibility score was 4.5 points. The distribution of scores was as follows: 5 points in 5 cases, 4 points in 1 case, 3 points in 2 cases, and 2 points in 2 cases. The lingual nerve continuity score in the affected area was lower than in the unaffected area in all 3 patients. The average visibility score of the lingual nerve was 2.67 on the affected side and 4 on the unaffected side.
Conclusion
This study confirmed that the preoperative localization of the facial and lingual nerves using MR neurography with the 3D-DESS-WE sequence was feasible and contributed to surgical planning for the parotid area and lingual nerve.

OBJECTIVE: A Study was undertaken to assess the family background of abandonment and clinical and social aspects in an institute for foreign adoption. The results were compared to the previous two reports from the institute. METHOD: A sample of 1,728 children from 1987 to 1992 formed the subjects of the study by the medical records in the institution. RESULTS: 1) The unmber of girls were more than that of male and ratio of male to female was 1:1.1, which was reduced compared to previous study. 2) The distribution less than one month of age was most commonly and increased compared to previous study. 3) The Place at birth was hospital most commonly. 4) The type of delivery was full-term one(61.5%) and tend to be increased. 5) Age distribution of monthers was from 16 years to 25 years mainly, 1,081 of them(62.5%) were from unmarried one and 409(37.4%) were from married one. 6) By classifying the cause of adoption, unmarried mothers occupied main one(62.5%), poverty(13.4%) extramarital relations(5.2%), divorce(2.9%) and death of parents in the order of frequency, tend to increased in unmarried mothers. 7) Disease pattern showed respiratory disease, jaundice, acute gastroenteritis, pneumonia, urinary tract infection, conjunctivitis in order of frequency. By care of foster mother at private home since 1988, the incidence of the transmissible disease was reduced. 8) Congenital anomalies were cleft and palate, hydrocele, umbilical hernia and congenital heart disease in order frequency. 9) Three hundred and eighty two babies were admitted to general hospital. The main disease were bhaline membrane disease. Jaundice, pneumonia and urinary tract disease, sepsis in the order of frequency. CONCLUSIONS: The ratio of male to female in the institution showed no definite difference and the age was tend to be younger. The cause of adoption was unmarried mother mainly. Respiratory disease in the institution and hyaline membrane disease in the hospitalized was most common.

Schwannomas rarely present as intraocular tumors and are often misdiagnosed as malignant melanoma. We describe a choroidal schwannoma confirmed by sclerouvectomy. A 30-year-old woman presented with a large nonpigmented intraocular mass of the choroid in the right eye and underwent surgical excision by sclerouvectomy. Histologically, the tumor was composed of a mixture of cellular solid components (Antoni A) and loose myxoid components (Antoni B). The tumor was eventually diagnosed as a schwannoma. Currently available ancillary studies are still of little value in definitively differentiating schwannomas from other choroidal tumors. In the case of atypical findings for a malignant melanoma, a benign neoplasm should be included in the differential diagnosis. This patient avoided enucleation by first having the mass excised. We are unaware of previous reports in which a choroidal schwannoma was diagnosed by surgical excision.

PURPOSE: The purpose of this study was to determine whether immunosuppressant, rapamycin could inhibit corneal angiogenesis induced by angiogenin and to evalutate its role by micropocket assay. METHODS: The rabbit's eye was implanted intrastromally into the superior cornea with pellet for the control group, pellet containing of angiogenin for the angiogenin group, and pellet containing of angiogenin and rapamycin for the angiogenin+rapamycin group. Biomicrographically, corneal angiogenesis was evaluated for 14 days after pellet implantation, based on the number and the length of new vessels. The neovascularized cornea also was examined histologically. RESULTS: We could observe that the angiogenin inducing corneal angiogenesis was inhibited by rapamycin. The score of neovascularization was significantly decreased in the angiogenin+rapamycin group than in the angiogenin group at 3, 7 and 10 days after pellet implantation (p<0.05). Histologically, the cornea of angiogenin+rapamycin group also showed much less new vessels than that of angiogenin group, in which inflammatory cells and edema was observed. CONCLUSIONS: Rapamycin appears to inhibit angiogenin induced angiogenesis in a rabbit corneal micropocket assay and may have therapeutic potential as an antiangiogenic agent.
