The ultimate goal of periodontal therapy is to promote the regeneration of lost periodontal tissue, there have been many attempts to develop a method to achieve this goal, but none of them was completely successful. The purpose of this study is to evaluate the effects of Bio-Oss(R) on alkaline Phosphatase (ALP) activity in human fetal osteoblasts (hFOB1). The results of this study were as follows, in ALP Activity, 100 microgram/ml Bio-Oss(R) treated group showed significantly increased value than negative control group, but positive group(10(-7) M dexamethasone treated group) showed the highest ALP activity at 3 day. In mineralization assay, numerous mineralized nodules were identified as darkly stained spots in 100 microgram/ml Bio-Oss(R) treated group than two control groups, whereas a small number of mineralized nodules were showed in the positive control. ALP may relate to the initial phase of bone nodule formation. On the basis of these results, this study showed Bio-Oss(R) is capable of accelerating new bone formation through hFOB1 differentiation in vitro.

A 73-year-old Korean male was admitted to Jeil hospital with clinical complaints of backache, cough, sputum, vomiting and diarrhea. He had a history of long term administration of prednisolone. At admission he was comatose and showed generalized pitting edema and anasarca. Laboratory data revealed leukocytosis, hyperproteinemia with hypoalbuminemia, sepsis, anemia and brown-colored urine. Stool examination revealed rhabditiform nematode larvae. By fecal cultivation, filariform larvae of Strogyloides were obtained and the patient was diagnosed as hyperinfection syndrome due to S. stercoralis infection. On the 3rd day of hospitalization, albendazole treatment was started and continued for 4 days. On the 7th dsy of hospitalization, sputum revealed filariform larvae. Total 619 parasitic adult females, expelled by chemotherapy, were collected from the diarrheal stool. However, the patient was discharged hopelessly and died at home.

The purpose of this study was to evaluate the effect of alprazolam on the stress that Korean raccoon dogs (Nyctereutes procyonoides koreensis) may experience while caught in a live trap by measuring their serum cortisol response. The animals were placed in a live trap with or without being pretreated with oral doses of alprazolam. In both groups, pre-trap blood samples were initially collected without anesthesia before the animals were positioned in the live trap; then post-trap blood samples were collected after the animals had remained in the live trap for 2 h. Changes in cortisol levels were observed using a chemiluminescent immunoassay. The level of cortisol increased in the control group and decreased in the alprazolam-pretreatment group (p < 0.05). In this study, we demonstrated that alprazolam pretreatment reduced stress during live trap capture.

The ultimate goal of periodontal therapy is the regeneration of periodontal tissue and the repair of function. For more than a decade there have been many efforts to develop ma- terials and methods of treatment to promote periodontal tissue regeneration. Recently many efforts are concentrated on the regeneration potential of material used in traditional medicine. Safflower(Carthamus tinctorius L.) seed extract(SSE) have long clinically used in Korea to promote bone formation and prevent osteoporosis. The purpose of this study was to examine the effects of SSE on bone formation in human osteoblastic cell line. Human fetal osteoblastic cell line(hFOB 1.19) was cultured with DMEM and SSE(1microgram/ml, 10microgram/ml, 100microgram/ml, 1mg/ml) at 34degrees C with 5% CO2 in 100% humidity. The proliferation, differentiation of the cell was evaluated by several experiments. Cell proliferation was significantly increased at 10microgram/ml, 100microgram/ml, 1mg/ml of SSE after 3 and 7 days incubation(p<0.05). Cell spreading assay was significantly increased at 100microgram/ml of SSE after 3 days and 1microgram/ml, 10microgram/ml, 100microgram/ml, 1mg/ml of SSE after 7 days(p<0.05). Alkaline Phosphatase(ALP) level was significantly increased in 10microgram/ml, 100microgram/ml of SSE(p<0.05). Collagen synthesis was significantly increased at 10microgram/ml, 100microgram/ml, 1mg/ml of SSE(p<0.05). A quantified calcium accumulation was significantly increased at 10microgram/ml, 100microgram/ml of SSE(p<0.05). ALP and osteocalcin mRNA was expressed in 100microgram/ml of SSE by RT-PCR. These results indicate that SSE are capable of increasing osteoblasts mineralization and may play an important role in bone formation.

BACKGROUND: The cell-mediated immunity is needed for eradicating the tubercle bacilli. Prosta- glandin(PG), especially PG E2, is involved in cellular immunosuppression. It is known that the PG E2 is suppressed by indo- methacin. For using indomethacin as a immunomodulator of intractable pulmonary tuberculosis(Tbc) patients, we measured the tuberculin skin test(TST) and the plasma PG E2 levels. METHOD: The forty-eight inpatients with sputum positive acid-fast stain bacilli were classified into 6 groups according to antiTbc chemotherapy history(new and intractable cases), plain chest roetgenogram(minimal and far advanced cases), and TST reaction(nagative and positive cases). Except for one group(n=2; new, minimal, and negative cases of TST reaction) of the 6 groups, all subjects(n=46) were measured for the plasma PG E2 levels with radioimmunoassay. RESULTS: 1) There was no significiant difference in the plasma PG E2 levels among A group(far advanced and positive TST reaction cases, n=10, 11.22 +/-2.86 pg/ml), B group(minimal and negative TST reaction cases, n=9, 11.35 +/-2.20) and C group(far advanced and positive TST reaction cases, n=7, 11.11+/-2.30) in the new cases(p >0.05). 2) There was no significiant difference in the plasma PG E2 levels between positive(n=10, 9.25 +/- 2.21) and negative(n=10, 8.25 +/- 1.13) groups by TST in the intractable cases(p>0.05). 3) Comparing the plasma PG E2 levels between new(n=26, 11.35 +/-2.41) and intractable(n=20, 8.75 1.78) groups, the intractable group had significi- antly lower plasma PG E2 levels(p<0.05). 4) There was no significiant difference in the plasma PG E2 levels between negative(n=19, 9.88 +/-2.43) and positive(n=27, 10.46 +/-2.56) groups by TST(p>0.05). 5) There was no significiant difference in the plasma PG E2 levels between male(n=32, 10.07 +/- 2.44) and female(n=14, 10.56 +/-2.70)(p >0.05). 6) There was no significiant difference in the plasma PG E2 levels among 2nd(n=5, 10.21 +/-2.86), 3rd(n=9, 9.97+/-2.47), 4th(n=13, 11.35+/-2.33) and 5th(n=19, 9.57+/-2.48) decades(p>0.05). 7) There was no significiant correlation between the induration sizes of the TST and the plasma PG E2 levels(r=0.054, p>0.05). CONCLUSION: From the above results, the plasma PG E2 levels of intract- able group are not higher as the authors had expected. There was no significiant difference in the plasma PG E2 levels by the lesion sizes of plain chest roetgengram and the induration sizes of TST, so more study will be needed to use the indomethacin as a immunomodulator for intractable pulmonary thberculosis patients.

STUDY DESIGN: Case report. OBJECTIVES: We report a case of spinal subarachnoid hematoma that developed after spinal anesthesia in a female patient who had no risk factors. SUMMARY OF LITERATURE REVIEW: Few case reports of spinal subarachnoid hematoma (SSH) after spinal anesthesia have been published. The incidence of SSH is much less than that of epidural hematoma. MATERIALS AND METHODS: A 56-year-old female patient underwent arthroscopic surgery on her right knee under spinal anesthesia. Automated patient-controlled analgesia (PCA) was applied after surgery. On day 2, the patient complained of lower back pain, headache, nausea, and vomiting, but there were no neurological signs in the lower extremity. At day 5, she had a moderate fever (38.4°) and continuous nausea and vomiting. Magnetic resonance imaging (MRI) was conducted on day 5 and a large subarachnoid hematoma was found. We immediately performed surgical hematoma evacuation. Her low back and buttock pain improved immediately, and all symptoms disappeared in a week without any neurological sequelae. RESULTS: The unusual and vague symptoms in this case made the diagnosis difficult, but spinal MRI confirmed SSH. Immediate surgical hematoma evacuation improved all symptoms and left no neurologic sequelae. CONCLUSIONS: SSH after spinal anesthesia may have cerebral symptoms that mimic the side effects of PCA. Early diagnosis by MRI and surgical evacuation of the SSH are a reasonable approach for this complication.

BACKGROUND: The incidence of cardiovascular and neurovascular diseases has been increasing with the aging of the population, and antiplatelet drugs (APDs) are more frequently used than in the past. With the average age of spinal surgery patients also increasing, there has been a great concern on the adverse effects of APD on spine surgery. To our knowledge, though there have been many studies on this issue, their results are conflicting. In this study, we aimed to determine the influence of APDs on spine surgery in terms of intraoperative bleeding and postoperative spinal epidural hematoma complication. METHODS: Patients who underwent posterior thoracolumbar decompression and instrumentation at our institution were reviewed. There were 34 APD takers (APDT group). Seventy-nine non-APD takers (NAPDT group) were selected as a control group in consideration of demographic and surgical factors. There were two primary endpoints of this study: the amount of bleeding per 10 minutes and cauda equina compression by epidural hematoma measured at the cross-sectional area of the thecal sac in the maximal compression site on the axial T2 magnetic resonance imaging scans taken on day 7. RESULTS: Both groups were homogeneous regarding age and sex (demographic factors), the number of fused segments, operation time, and primary/revision operation (surgical factors), and the number of platelets, prothrombin time, and activated partial thromboplastin time (coagulation-related factors). However, the platelet function analysis-epinephrine was delayed in the APDT group than in the NAPDT group (203.6 seconds vs. 170.0 seconds, p = 0.050). Intraoperative bleeding per 10 minutes was 40.6 ± 12.8 mL in the APDT group and 43.9 ± 9.9 mL in the NAPDT group, showing no significant difference between the two groups (p = 0.154). The cross-sectional area of the thecal sac at the maximal compression site by epidural hematoma was 120.2 ± 48.2 mm2 in the APDT group and 123.2 ± 50.4 mm2 in the NAPDT group, showing no significant difference between the two groups (p = 0.766). CONCLUSIONS: APD medication did not increase intraoperative bleeding and postoperative spinal epidural hematoma. Therefore, it would be safer to perform spinal surgery without discontinuation of APD therapy in patients who are vulnerable to cardiovascular and neurovascular complications.
