No effective therapy has yet developed for liver fibrosis/cirrhosis by directly inhibiting the accumulation of extracellular matrix. This study was undertaken to determine the effect of tetrandrine in rat model of liver fibrosis induced by carborn tetrachloride (CCl4) administration intraorally. Tetrandrine, a calcium channel blocker, is anti-inflammatory constituent of the families Menispermaceae and Ranunculaceae, which have been used as folk remedies in China. Repeated administration of CCl4 for 14 weeks to rats induced liver fibrosis with steatosis. Rats were killed after 4, 8 or 14 weeks of treatment with CCl4, CCl4 tetrandrine (30 mg/kg) or CCl4 tetrandrine (50 mg/kg). The histopathological findings of liver were observed semi-quantitatively by light microscopy and volume percentage of the collagen deposition was determined by image analyzer. Tetrandrine inhibited collagen deposition induced by CCl4 administration, as shown by less severe steatosis and fibrosis and significantly decreased volume percentage of collagen fibers in CCl4 tetrandrine treated animals compared with CCl4 only group. Thus, the administration of tetrandrine holds great promise for treating subjects with liver fibrosis/cirrhosis as a result of chronic hepatic injury.

Nasal chondromesenchymal hamartoma is a distinctive mixed mesenchymal lesion of sinonasal region with a complex histologic appearance and benign clinical course and clinicopathologically similar to those of the mesenchymal hamartoma of the chest wall of infancy. We report a case of nasal chondromesenchymal hamartoma occurred in the right nasal cavity in a 3-month-old female. She was admitted with a history of profuse nasal bleeding and obstruction. CT revealed complex solid and cystic mass, measuring 3.5x2.5x2.5 cm in dimensions which filled the right nasal cavity and extended into ethmoid sinus and cribriform plate. The received piecemeal fragments of tissue were brown tan-colored firm semitranslucent tissue with a cartilaginous appearance. Microscopically, the basic morphologic elements were irregular islands of hyaline cartilage and myxoid to spindle cell stroma with various cellularity.

We studied thirteen, all male, patients who had trans-scaphoid perilunar dislocation(stage I, 5 cases) and dislocation of lunate(stage IV, 8 cases). Age of patient was ranged from 25 years to 49 years(avr. 36 years)and the most common cause of injury was fall down(6 cases, 46%). Seven acute cases, diagnosed and treated within 3 weeks from injury, were treated by open reduction and K-wire fixation(5 cases), and K-wire fixation and bone graft(1 case) and Herbert screw for fracture of scaphoid(1 case). Six chronic cases diagnosed and treated after 3 weeks from injury were treated by open reduction and K-wire fixation(1 case), K-wire fixation and bone graft(1 case), removal of lunate(2 cases), and arthroplasty using muscle after removal of lunate(2 cases). Thirteen cases were followed up for average 33 months(from 13 months to 81 months). Grip power was evaluated as excellent or good in 8 cases and fair in 5 cases. Range of motion of wrist joint was decreased 21 degrees in flexion, 22 degrees in extension, 4 degrees in ulnar deviation, and 5 degrees in radial deviation of wrist joint, compared with uninjured side. Carpal height and carpal height ratio were decreased to 33.1 and 0.51, compared with normal 35.8(p=0.001) and 0.55(P < 0.001), respectively. Between 2 groups of acute and chronic cases, no significant differences were noted in carpal height or carpal height ratio. The surgical treatment of perilunar fracture-dislocation has not simple option, therefore, we would recommend the early diagnosis and exact anatomical reduction.

PURPOSE: Genetic modification technique is widely used in plants for improving crop yields and qualities, and reducing pesticide use. Zoysia japonica is one of the widely planted grasses for lawning. Pollenless herbicide-tolerant genetically modified (GM) grasses (JG21-MS1 and JG21-MS2) were developed under surveillance for possible biohazard. Grasses may cause allergic contact dermatitis with direct contact on human skin. Patch testing with allergens was adopted to compare the incidences of allergic contact dermatitis to GM grass leaves with those of wild-type grass. METHODS: Patch testing with controls and leaves of wild-type and GM grasses was performed in individuals with informed consent. RESULTS: Ninety-seven individuals (mean age, 32+/-8 years; 48% males) were enrolled. For nickel sulfate as a positive control, 38 subjects (39.2%) were positive. For GM grasses, 10 (10.3%) showed positive patch test results and 11 (11.3%), for wild-type grass, the proportions of which were similar among the tested grasses. CONCLUSION: JG21-MS1 and JG21-MS2 are not more biohazardous than wild-type grass in the risk of allergic contact dermatitis.

The diagnostic importance of finding an appendicolith in the plain x-ray of the abdomen has been well documented. However, most of the papers so far published have stressed x-ray findings of the preoperative abdomenin acute appendicitis. In the present study we have attempted to correlate incidences of appendicoliths insurgical specimen and plain x-ray of the abdomen. The materials were 37 surgical specimens of the appendix removed for acute appendicits at St. Mary's Hospital, St. Paul's Hospital, Kang Nam Hospital, Holy Family Hospital and Our Lady of Mercy Hospital of Catholic Medical College during the period of 6 months from August 1980. Each surgical specimen was subjected to soft tissue radiography to detect calcified appendicolith. Then the preoperative x-raysof abdomen were retrospectroscopically analysed for the presence of radiographically demonstrable appendicoliths.Our study revealed that in as many as 32% of 37 surgical specimens one or more calcified appendicoliths were demonstrated radiographically whereas only one of these was identified as such in the preoperative x-ray film ofthe abdomen. Such a great discrepancy between the incidences of appendicoliths in the surgical specimen andpreoperative x-ray films of the abdomen are ascribed to (1) relative smallness of appendicoliths (87% of the stones measured less than 1cm in diameter in radiographs of surgical specimen in our series), (2) overlapping of these small stones on the right iliac bone and (3) underpenetrating of the iliac bone area in x-ray films of theabdomen. For improving detctability of appendicoliths therefore it is recommended that the technique of radiography of plain abdomen should be such that a small appendicolity overlying the iliac bone can be brought outof trabecular shadows.

BACKGROUND: Epidural morphine has been commonly used to provide postoperative pain relief, but it has many side effects such as nausea, vomiting, respiratory depression, and pruritus. The purpose of this study was to evaluate the analgesic efficacy and side effects by combination use of epidural morphine and butorphanol. METHODS: Forty five patients were randomly divided into 3 groups. For group I, a bolus of 4.7 ml of saline and 3 mg of morphine were administered. For group II, a bolus of 4.2 ml of saline and 3 mg of morphine and 1 mg of butorphanol were administered. For group III, a bolus of 3.2 ml of saline and 3 mg of morphine and 3 mg of butorphanol were administered. Continuous epidural analgesia were administered for all groups; group I (saline 99.4 ml and morphine 6 mg), group II (saline 98.4 ml, morphine 6 mg, and butorphanol 2 mg), group III (saline 96.4 ml, morphine 6 mg, and butorphanol 6 mg) by two day infuser, 2 ml/hr. We compared the side effects and analgesic effect of the three groups for 2 days. RESULTS: The incidence of pruritus, nausea and vomiting was reduced significantly in the group II and III, but the incidence of somnolence increased in the group III. There were no significant differences in analgesic effect and the other side effects among the three groups. CONCLUSION: Above results suggest that the addition of butorphanol to morphine in epidural infusion reduce the incidence of pruritus, nausea and vomiting, but increase the incidence of somnolence.

Journal of Korean Burn Society 2012;15(1):39-44
PURPOSE: Defensins are important components of innate immune system. These peptides have antimicrobial activity against a wise variety of pathogens that associated with burn wound infection. In particular, human beta-defensins are expressed in normal epidermal region and showed differential expression of some skin disease. We investigated that expression of human beta-defensin by in vitro and ex-vivo by thermal condition. METHODS: To investigate the expression of human beta-defensins in acute burn condition, we cultured keratinocytes and used to rat's skin at this experiment. After thermal condition, we showed the expression of beta-defensins-2 (hBD-2), -3 (hBD-3), keratins, keratinocyte differentiation and junction protein levels by RT-PCR and immunohistochemistry (IHC). RESULTS: HBD-2 & involucrin were down-regulated from 1 hr to 8 hrs in mRNA level. But others were not changed in mRNA level. In protein level, hBD-3 was decreased but pan-cytokeratin and beta-catenin were not changed. CONCLUSION: HBD-2 was down-regulated in thermal injury. Because thermal injury could induce the influence of keratinocyte differentiation and the decrease of skin protection ability. Our results suggested that human beta-defensins plays an important role in protection by several injury.
