  • This study was carried out to compare the efficacy of sodium carboxymethyl cellulose (SCMC) with the combination of low molecular weight heparin (LMWH) and SCMC for the prevention of postoperative adhesions in the dog. After laparotomy, abrasions were made on the surface of ileal serosa in 17 dogs. The animals were randomly divided into the control group (N = 5) which received no treatment, the SCMC-treated group (N = 6), and the SCMC & LMWH-treated group (N = 6). Hematologic values were monitored before laparotomy and 1, 4, 7, 10 and 14 days after laparotomy. The location and score of adhesion were assessed at second laparotomy 3 weeks later, Although the mean adhesion score both in the SCMC-treated group (7.17${\pm}$1.17) and in the SCMC & LMWH-treated group (4.50${\pm}$1.38) was found to be significantly lower than that in the control group (9.40${\pm}$0.89) (p<0.01 and p<0.01, respectively), more favorable adhesion prevention was achieved in the SCMC & LMWH-treated group in comparison with the SCMC-treated group without any hemor-rhagic complications (p<0.01). This study could conclude that SCMC & LMWH are highly effective in prevention against postoperative adhesion in the dog.

  • A 33 year old male patient was admitted with 20 years history of recurrent hemoptysis. On clinical examination, mild left chest discomfortness and foul odored sputum with occasional rusty hemoptysis were principal complaints noted. Chest X-ray film revealed moderately advanced active tuberculosis lesion on both upper lung fields, and hen-egg sized mass surrounded with linear crescent of air shadow in a cavity on his left upper lung field. On left thoracotomy, dense pleural adhesions on left apicoposterior segmental surface with multiple lymphnode enlargements were noted, and the soft encapsulated mass of $5{\times}5{\times}8cm$ was localized in the apicoposterior segment of the left upper lobe. Apicoposterior segment with anterior segment of the left upper lobe was resected. Cavity was opened to find a rusty grayish colored, fragile mass, which was confirmed as "fungus ball" of aspergillosis by histological section slide with Gomori staining. The authors report one case of pulmonary aspergilloma superinfected with previous long standing pulmonary tbc.

  • This paper describes the physical properties of filled Nylon6 composites resin with nano-sized carbon black particle and graphite nanofibers prepared by melt extrusion method. In improving adhesions between resin and fillers, the surface of the carbon filler materials were chemically modified by thermo-oxidative treatments and followed by treatments of silane coupling agent. Crystallization temperature and rate of crystallization increased with increases in filler concentration which would act as nuclei for crystallization. The silane treatments on the filler materials showed effect of reduction in crystallization temperature, possibly from enhancement in wetting property of the surface of the filler materials. Percolation transition phenomenon at which the volume resistivity was sharply decreased was observed above 9 wt% of carbon black and above 6 wt% of graphite nanofiber. The graphite nanofibers contributed to more effectively in an increase in electrical conductivity than carbon black did, on the other hand, the silane coupling agent negatively affected to the electrical conductivity due to the insulating property of the silane. Positive temperature coefficient (PTC) phenomenon, was observed as usual in other composites, that is, temperature increase results conductivity increase. The dispersity of the fillers were excellently approached by melt extrusion of co-rotational twin screw type and it could be illustrated by X-ray diffraction and SEM.

  • Surgical treatments for arthritis in the first metatarsophalangeal joint include arthrodesis, interposition arthroplasty using silicone or meniscus cartilage, and rarely arthroplasty. Although arthrodesis was performed successfully, pain can persist if the angle of fusion was inappropriate. Interposition arthroplasty can be tried for the treatment of persisting pain after the arthrodesis. Interposition arthroplasty using tensor fascia lata is known that has low risk of adhesions and easy to harvest. Compared to autologous grafts, grafting rates is high and low risk of rejection additionally. Herein, we report a successfully managed arthritis with severe pain with interposition arthroplasty using tensor fascia lata after a failed metatarsophalangeal joint arthrodesis.

  • A 35-year-old female patient who had been paraplegic since her upper thoracic cord injury one and a half years before was presented with a syringomyelia involving C7 to T2 cord segments on follow-up magnetic resonance imaging(MRI). Her pain on the chest and bilateral axilla worsened since about 2 years after initial injury, and MRI demonstrated a progressively enlarging cystic syrinx cavity of the cervicothoracic cord. The posttraumatic syringomyelia was managed operatively by lysis of the arachnoid adhesions, myelotomy, and expansile duraplasty. Post-operatively her pain was relieved, and MRI showed decrease in size of the syrinx, and digital infrared thermographic imaging(DITI) showed diminution of the hyperthermic area on the anterior chest. In conclusion, the posttraumatic syringomyelia can be managed successfully without shunt operation. It seems apparent that expansile duraplasty is effective in controlling the posttraumatic syrinx.

  • Transforming Growth Factor (TGF)-$\beta$ family, including TGF-$\beta$, bone morphorgenic protein (BMP), and activn, plays an important role in essential cellular functions such as proliferation, differentiation, apoptosis, tissue remodeling, angiognesis, immune responses, and cell adhesions. TGF-$\beta$ predominantly transmits the signals through serine/threonine receptor kinases and cytoplasmic proteins called Smads. Since the discovery of TGF-$\beta$ in the early 1980s, the dysregulation of TGF-$\beta$/Smad signaling has been implicated in the pathogenesis of human diseases. Among signal transducers in TGF-$\beta$/Smad signaling, inhibitory Smads (I-Smads), Smad6 and Smad7, act as major negative regulators forming autoinhibitory feedback loops and mediate the cross-talking with other signaling pathways. Expressions of I-Smads are mainly regulated on the transcriptional levels and post-translational protein degradations and their intracellular levels are tightly controlled to maintain the homeostatic balances. However, abnormal levels of I-Smads in the pathological conditions elicit the altered TGF-$\beta$ signaling in cells, eventually causing TGF-$\beta$-related human diseases. Thus, exploring the molecular mechanisms about the regulations of I-Smads may provide the therapeutic clues for human diseases induced by the abnormal TGF-$\beta$ signaling.

  • Intrapleural instillation of tetracycline as a preventive measure against recurrence in spontaneous pneumothorax was performed at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital for 3 years from Jul. 1984 to Aug. 1987. In this period, 124[70.0%] out of 177 patients of spontaneous pneumothorax who received closed thoracostomy were followed up. Tetracycline pleurodesis was applied to 32 cases. The recurrence rate of the tetracycline instillation group was lower than that of noninstillation group. In patients with first attack, the recurrence rate was 12.5% in the instillation group and 35.3% in the noninstillation group. In the second episodes, 25.6% and 83.3%[p< 0.01], in the third episodes 25.0%, 100.0%[p< 0.05]. In total cases, 18.8% and 39.8%[p< 0.05] of recurrence rates were observed. Systemic or local reactions such as fever, chest pain, and pleural effusion were observed in 23 patients[71.9%] after instillation, but all were transient and benign without sequelae. In cases of systemic or local reactions the recurrence rate was lower than that with no reactions but with no statistical significance. In the four patients primarily treated with tetracycline pleurodesis who then underwent thoracotomy, mild alterations were shown in the pleurae except dense adhesions at the previous thoracotomy sites. There was no significant difference between the two groups in terms of durations of hospitalization and post-treatment recurrences.

  • Lectin activities and chemical characteristics of Escherichia coli, Lactobacillus spp. and Bifidobacterium spp. originating from the porcine cecal mucosal layer were studied based on hemagglutination assay (HA) and hemagglutination inhibition assay (HIA). Although all the bacterial strains were able to agglutinate erythrocytes of porcine or rabbit origin, much higher HA titers were consistently observed for Lactobacillus spp. than for E. coli or for Bifidobacterium spp. A remarkable reduction in HA titers occurred by the treatment of E. coli and Lactobacillus spp. with protease or trypsin and of Bifidobacterium spp. with protease, trypsin or periodate. There were no significant effects on the HA titers of the three groups of bacteria after the treatment with lipase. Hemagglutination of E. coli was strongly inhibited by D (+)-mannose and D (+)-galactose; Lactobacillus spp. by $\alpha$-L-rhamnose and methyl-$\beta$-galactopyranoside; Bifidobacterium spp. by D (+)-alactose, $\alpha$-L-rhamnose, $\alpha$-L-fucose, L (+)-arabinose, D (+)-mannose, D (-)-fructose at a relatively low concentration (1.43 to 3.75 mg/ml). These results, combined with the enhanced HA activities of the three bacterial strains by modification of rabbit erythrocytes with neuraminidase and abolished HA activity of E. coli after treatment with $\beta$-galactosidase, indicate that it might be the glycoproteinous substances surrounding the surface of the bacterial cells that are responsible for the adhesions of these microorganisms by recognizing the specific receptors on the red blood cell.

  • A case report of a post-traumatic syringomyelia in a 29-year old male, developed 15 years after an L1 burst fracture, is presented. On preoperative MRI, the syrinx extended cephalad above the fracture site through the whole thoracic and cervical cord. Serial myelo-CT was performed to evaluate the dynamics of CSF. It was managed by lysis of the arachnoid adhesions, syringosubarachnoid shunt, and expansile duraplasty. After surgery, the patient's symptoms improved, and marked decrease of the syrinx was seen on postoperative MRI. The pathophysiology, the role of preoperative diagnostic methods especially serial myelo-CT, and the contmporary management modalities for posttraumatic syringomyelia is reviewed along with the pertinent literature.
