PURPOSE: Ginseng has been reported to reduce blood glucose levels in diabetic animals and patients, and it is also reported to slow the aging process by acting as an anti-atherosclerotic agent or as an anti-oxidant. This study was designed to investigate whether ginseng and irbesartan can prevent the development of diabetic nephropathy in streptozotocin-induced diabetic rats. METHODS: Diabetes was induced in 7 week-old male Sprague-Dawley rats by intravenous injection of 60 mg/kg streptozotocin. Ginseng(1 g/kg/day) or irbesartan (20 mg/kg/day) was given to diabetic rats for 25 weeks. Blood glucose and body weight were checked weekly and urinary albumin excretion was evaluated every 6 weeks. At the end of the experiment, the kidneys were weighed and sliced for microscopic examination. Glomerular size and hyaline deposition were measured on light microscopy(on Masson' trichrome stain and PAS stain) and thickness of glomerular basement membrane(GBM) on electron microscopy. Renal histologic findings of ginseng or irbesartan treated rats were compared with those of normal control and diabetic control groups. RESULTS: The weight gain in diabetic rats was significantly reduced, and the final body weight of diabetic rats was lower than that of normal control rats. There was no significant difference in body weights between the diabetic control, ginseng, and irbesartan treated groups. Mean levels of blood glucose were significantly increased in diabetic rats compared to normal rats, but there was no significant difference in blood glucose among the three groups of diabetic rats. Urinary albumin excretion was increased in the diabetic groups compared to the normal control group, and it was significantly decreased in the irbesartan treated group compared to the diabetic control group at 13th week of treatment. At the end of the experiment, the kindeys of the diabetic rats were examined and showed significantly enlarged than those of the normal rats, and the ratio of kidney weight to body weight was decreased in the ginseng treated group compared to the diabetic control and irbesartan treated group. There was no significant difference in the size of glomerulus, the thickness of GBM, and glomerular hyaline deposition among the three diabetic groups. CONCLUSION: There was no significant hypoglycemic effect of ginseng in streptozotocin-induced diabetic rats. Renal hypertrophy was relatively milder in the ginseng-treated group, but there was no difference in findings of renal histology between the treatment groups.

A one step reverse transcription PCR (RT-PCR) combined nested PCR was set up to increase efficiency in the diagnosis of canine distemper virus (CDV) infection after developement of nested PCR. Two PCR primer sets were designed based on the sequence of nucleocapsid gene of CDV Onderstepoort strain. One-step RT-PCR with the outer primer pair was revealed to detect 10(2) PFU/ml. The sensitivity was increased hundredfold using the one-step RT-PCR combined with the nested PCR. Specificity of the PCR was also confirmed using other related canine virus and peripheral blood mononuclear cells (PBMC) and body secretes of healthy dogs. Of the 51 blood samples from dogs clinically suspected of CD, 45 samples were revealed as positive by one-step RT-PCR combined with nested PCR. However, only 15 samples were identified as positive with a single one step RT-PCR. Therefore approximately 60% increase in the efficiency of the diagnosis was observed by the combined method. These results suggested that one step RT-PCR combined with nested PCR could be a sensitive, specific, and practical method for diagnosis of CDV infection.

OBJECTIVES: To investigate the common causes of persistent septal deviation in revision septoplasty and to report the surgical techniques and results to correct them. METHODS: A total of 100 consecutive patients (86 males) who had revision septoplasty due to persistent septal deviation from 2008 and 2014 were included in the study. Their mean age was 35.6 years and the mean follow-up duration was 9.1 months. Presenting symptoms, sites of persistent septal deviation, techniques used to correct the deviation, and surgical results were reviewed. RESULTS: The mean interval between primary and revision surgery was 6.2 years. Forty-eight patients received revision septoplasty and 52 received revision septoplasty combined with rhinoplasty. Nasal obstruction was the most presenting symptom in almost all patients. The most common site of persistent septal deviation was middle septum (58%) followed by caudal septum (31%). Correcting techniques included further chondrotomy and excision of deviated portion in 76% and caudal batten graft in 39%. Rhinoscopic and endoscopic exams showed straight septum in 97% and 92 patients had subjective symptom improvement postoperatively. CONCLUSION: Middle septum and caudal septum were common sites of persistent deviation. Proper chondrotomy with excision of deviated middle septum and correction of the caudal deviation with batten graft are key maneuvers to treat persistent deviation.

Objectives: . Nonsurgical rhinoplasty using threads has gained popularity in recent years. While the benefits of this procedure have been emphasized, possible complications and their management are not well-known. This study aimed to present the surgical management and results of the complications of thread rhinoplasty. Methods: . We retrospectively reviewed the medical records of seven patients who underwent revision rhinoplasty due to the complications of thread rhinoplasty from January 2018 to May 2021. The presentation of complications, detailed surgical procedures, and outcomes of revision rhinoplasty were reviewed. Results: . Visible or extruded threads at the tip were the most common complication, followed by dorsum irregularity. All the threads were unabsorbed and intact in shape, even several years after insertion. Thread removal necessitated careful tissue dissection, resulting in the loss of tip support and dorsal irregularity. To restore the tip support and camouflage the dorsum shape, an autologous tissue graft was needed. Conclusion . Removal of threads at the tip and dorsum was accompanied by structural weakening and partial tissue loss, which required tip support restoration and dorsum camouflage.

Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

PURPOSE: Mycobacterium abscessus belongs to the group of rapid-growing atypical mycobacterium. The organism is ubiquitous and is found in soil, dust, and water. Although it rarely causes disease in humans, Mycobacterium abscessus has been associated with soft tissue infection. To the best of our knowledge, this is the first case report of facial soft tissue Mycobacterium abscessus infection in a healthy child in Korea. METHODS: A 12-year-old girl presented with an erythematous skin lesion with serous discharge on her chin, which had been present for 3 weeks. On her history, she had a laceration wound on her chin at public bath and the lesion was repaired at emergency department immediately. Although conventional soft tissue infecton treatment, her lesion remains unhealed state and had serous discharge for 2 months. Moreover, we found a 1cm sized nodular mass on her chin. Therefore we performed excision operation and referred the specimen to the laboratory for microbial and histopathologic study. RESULTS: Pathology report confirmed the mass was enlarged lymph node with chronic necrotizing granulomatous inflammation with central microabscess. Non-Tuberculous mycobacterium identification test through tissue specimen resulted Mycobacterium abscessus. We prescribed clarithromycin for three weeks by oral administration as well as performed wound debridement and mass excision via previous wound. This way, her lesion appeared to be complete healing with minimal scarring. There were no evidence of inflammation sign or palpable mass. CONCLUSION: Although the prevalence is rare, Mycobacterium abscessus infections of soft tissue should be considered even in a healthy child with a lesion caused by trauma or which fails to respond to conventional treatment.

BACKGROUND AND OBJECTIVES: No definite concepts or nomenclature have yet been established in Korean for a number of different grafts used frequently in Korean rhinoplasty. The aims of this study were to define indications and usages of grafts frequently used in Korean rhinoplasty and to suggest appropriate Korean nomenclatures for these grafts. MATERIALS AND METHOD: We prepared diagrams and explanations for the grafts frequently used in rhinoplasty in Korea and suggested Korean nomenclature that were considered the most appropriate. We carried out a survey on the rhinoplasty experts in order to reach a consensus on the nomenclature. We also reviewed recent Korean articles on rhinoplasty to investigate how names of each graft had been translated into Korean nomenclature. RESULTS: We classified grafts according to anatomical locations; the nasal dorsum, the nasal tip, the alar region, and the alar base. Grafts of the nasal dorsum included radix graft, dorsal onlay graft, dorsal sidewall onlay graft, and spreader graft. Grafts of the nasal tip were the columellar strut, shield graft, buttress graft, cap graft, and septal extension graft. The alar batten graft, alar rim graft, composite alar rim graft, lateral crural onlay graft, and lateral crural strut graft belonged to grafts of the alar region. Grafts of the alar base included the columellar plumping graft, premaxillary graft, and alar base graft. The names of all these grafts were translated into Korean. CONCLUSION: We set definitions, indications, and usages of each graft, and suggested the most appropriate Korean nomenclature. We hope that this nomenclature can be widely accepted and used in future papers and books on Korean rhinoplasty.

Second branchial cleft cysts are the most common type of branchial abnormalities and usually found high in the neck. Oropharyngeal presence of branchial cleft cyst is very rare. We report a case of oropharyngeal branchial cleft cyst in 2-yr-old girl with about 1x1 cm sized cystic mass, which had not any specific symptom. It was removed completely under impression of mucocele and did not have tract-like structure. However, cyst had a squamous epithelium-lined wall with lymphoid aggregation in histopathologic study, which was characteristic finding of branchial cleft cyst. Patient discharged without any complication and there was no evidence of recurrence for 18 months follow-up. We review reported oropharyngeal or nasopharyngeal presentation of these cases in English literature and embryological explanation.
