Objective: To evaluate anti-diabetic effect of Caulerpa lentillifera (C. lentillifera).Methods:The inhibitory effect of C. lentillifera extract on dipeptidyl peptidase-IV andα-glucosidase enzyme was measured in a cell free system. Then, interleukin-1β and interferon-γinduced cell death and insulin secretion were measured in rat insulinoma (RIN) cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and ELISA kit, respectively. Glucose uptake and glucose transporter expression were measured by fluorometry and western blotting, using 3T3-L1 adipocytes.Results: C. lentillifera extract significantly decreased dipeptidyl peptidase-IV and α-glucosidase enzyme activities, and effectively inhibited cell death and iNOS expression in interleukin-1βand interferon-γ induced RIN cells. Furthermore, C. lentillifera extract significantly enhanced insulin secretion in RIN cells and glucose transporter expression and glucose uptake in 3T3-L1 adipocytes.Conclusions:Thus, our results suggest that C. lentillifera could be used as a potential anti-diabetic agent.

Introduction: This study examined the factors related to the amount of blood loss and transfusion after primary total hip arthroplasty. Materials and methods: Sixty THRA patients, who had records of perioperative complete blood counts and transfusion, were enrolled in this study. Age, gender, diagnosis, use of cement, size of an incision, operative time, intraoperative crack, estimated blood loss, use of suction drain and the amount drained were used as possible variables. Results: The decrease in the serum hemoglobin level immediately after and 1 day after surgery was 3.18 and 3.90g/dL respectively. An average of 2.30 units were transfused in 78.3% of cases. The preoperative serum hemoglobin level, the use of a suction drain and the amount drained was related to the total amount of transfusion. Adverse transfusion reactions were found to be associated with the amount of transfusion Discussion: The reduction in the hemoglobin level and total amount of blood transfused showed no relationship with the variances associated with the surgical techniques. The total amount of blood transfused was significantly lower in the groups that had no suction drain. Therefore, a reduction in the volume of intraoperative transfusion and avoiding use of a suction drain can reduce the total amount of blood needed and reduce the adverse reactions of the transfusion.

STUDY DESIGN: Retrospective clinical study. OBJECTIVES: To assess the efficacy of a cortical bone trajectory pedicle screw (CBT-PS) for the treatment of lumbar pyogenic spondylodiscitis. SUMMARY OF LITERATURE REVIEW: Pedicle screws were used for surgical treatment of pyogenic spondylodiscitis to prevent instability and deformity. CTB-PS are typically inserted from the inferomedial to superolateral direction of the pedicle and have yielded satisfactory results in degenerative or osteoporotic spinal disorders. MATERIALS AND METHODS: Eight patients with single segment lumbar pyogenic spondylodiscitis were analyzed. At first, anterior debridements and interbody fusions were perfomed with autogenous strut bone grafts, followed by posterior fixations and fusions with CBT-PS. The lordotic angles of operated levels were checked at the preoperative, postoperative, and final follow-ups. Visual analogue scales (VAS) were checked at the preoperative and final follow-ups. RESULTS: Lesion sites were found at four L3-4, three L4-5, and one L2-3. Follow-ups were held at 26.13±8.23 months. The lordotic angles at preoperative, postoperative, and final follow-ups were 12.13±3.09°, 14.63±3.16°, and 12.75±3.99°, retrospectively. There were significant differences between results from the preoperative-postoperative and postoperative-final follow ups. There was no difference in the preoperative-final follow up. There was a significant difference between the VAS at the preoperative and final follow-ups (8.13±0.83 and 2.38±0.92, retrospectively). Complete bony unions of were observed at the final follow-up in all cases. CONCLUSIONS: The advantages of using a CBT-PS for lumbar pyogenic spondylodiscitis included the ability to minimize damage from the screw for both the posterior structure damage and the operated anterior area to prevent instability and deformity, and to achieve rigid bone union. CBT-PS is a potential surgical option for pyogenic spondylodiscitis.

The posterior cruciate ligament is an anatomically and biomechanically complex structure. PCL injuries are reported to occur in 1-40% of acute knee injuries, with isolated PCL tear, less common than PCL tears combined with other Iigament injuries. Controversy exists concerning the geatment of the PCL injures. Recently, arthroscopic techniques of PCL reconstruction are becoming nore refined and reproducible. Between July 1993 and May 1995, 25 operations for PCL rupture were performed in our hospital. At the follow-up examinations we noted mild to moderate posterior instablilty which was not noted at the time of operation and during the immediate postoperative period. We reviewed type (if injuries, amplitude of initial posterior tibia1 translation, surgical techniques, which seemcd to be in relation ivith the postoperative instabilities. At final follow-up, the mean Lysholm knee score was 86 points, and the posterior tibial translation 6.5mm on posterior stress radiographs. The ligament augmentation device provided no benefit. The ideal positioning and fixation of the graft and protection of the graft from abrasion seemed to be important to get a good results.

We reviewed 205 hips (in 151 patients, 125 men and 26 women) which were diagnosed osteonecrosis of femoral head and treated with bipolar endoprosthesis from 1985 to 1993 in Seoul National University Hospital to delineate the efficacy and indication of use of bipolar endoprosthesis in osteonecrosis. They were followed up for an average of 56 months (16 to 100 months). The mean age at operation was 44 years (21 to 84 years). The types of prosthesis used were as follows : Omnift (107), AML (57), Harris-Galante (19) and others (22). The preoperative Harris hip score improved from 49 points preoperatively to 89 points at last follow-up. The pain score improved from 18 points to 39 points, activity score from 9 points to 12 points and gait scare from 19 points to 31 points. The improvement pattern of activities and gait was converse, but that of pain was diverse. One hundred and seventy-eight hips (87%) were satisfactory (Harris hip score : more than 80 points) and 27 (13%) were unsatisfactory. Radiologic findings of last follow-up showed stable bony fixation in 186 hips (91%), stable fibrous fixation in 12 hips (6%) and unstable fixation in 7 hips (3%), Ten migrations of prosthesis were noted: cup migration 5 (2.4%) and stem sinking 5 (2.4%). Heterotopic ossification was noted in 9 (4.4%). Osteolysis in acetabular side was observed in 6 (3%) and in femoral side, 22 (11%). Complications were as follows : 4 stem loosening (1.9%), 5 fixed varus position of cup (2.4%) and 1 dislocation of cup (0.5%). Revision was performed in 4 (1.9%) and the causes were 1 infection, 1 protrusio acetabuli, 1 stem loosening and 1 cup dislocation. In conclusion, biopolar endoprosthesis generally gave good results. However, the improvement of pain was unpredictable. Increasing tendency of osteolysis was noted with increasing follow-up duration. Long-term follow-up is mandatory for the accurate determination of osteolysis.

Henoch-Sch nlein purpura is a small-vessel vasculitis characterized by palpable purpura, abdominal pain, hematuria and arthralgia. Joint involvement occurs in 2/3 of the cases and the joint symptoms are misapprehended as an orthopaedic problem because they are often severe and occurs before characteristic purpura. It has been reported that the joint symptoms can be improved without any sequelae. But, recently some authors suggest that severe joint destruction can occur when combined with rheumatoid arthritis and the patients are FILA-DR4 positive. So, the regular follow-up for joint symptoms and screening test for the risky patients having possibility for progression of arthritis are required. In order to increase the attention of the orthopaedic surgeons on this disease and study the progression of joint symptoms, possibility of development of screening test for the risky patients and the characterisitics of the disease, we analyzed the 58 patients of Henoch-Sch nlein purpura. The following results were obtained. Among 58 patients 34 cases were male and 25 cases were female, 5 to 10-year-old children were affected more frequently and the disease occurs frequently in spring and winter season. Joint symptoms developed in 22/58 patients(37.9%) and occurs before characteristic purpura in 5/22 patients(22.7%) among the joint symptom-developed patients. Knee and ankle were affected in most patients and the inflammatory signs such as high fever, leukocytosis and elevated ESR were accompanied with joint symptom, so it resembled the symptoms and signs of pyogenic arthritis. Most of the patients recovered without remaining sequelae but 9 patients(15.5%) among joint symptom-developed patients complained repeated attacks of arthralgia. The HLA B27 were all positive in those patients. So, it was assumed that the joint symptom in Henoch-Sch nlein purpura has a correlation with genetic environment and through the broad prospective study, the HLA typing can be a screening test for the risky group prone to suffer from repeated attack or aggravation of arthritis.

OBJECTIVE: The purpose of this study attempts to determine the endocrinologic characteristics and changes in glucose metabolism before/during pregnancy according to different body weights in women with Polycystic ovarian syndrome (PCOS). METHODS: 94 women dia with PCOS were evaluated through measuring serum hormone levels and oral glucose tolerance tests preconceptionally and gestationally. RESULTS: In patients who were of normal weight showed significantly increased serum LH levels compared to those who were overweight (12.8+/-0.9 Vs. 7.1+/-0.8 mIU/ml, p= 0.000), and the serum levels of insulin was increased significantly in the overweight group (7.1+/-0.7 Vs. 15.2+/-2.8 ulU/ml, p= 0.000). the IGFBP-I (32.8+/-10.6 Vs. 8.3+/-2.5 ng/ml, p=0.034) and SHBG (55.8+/-4.2 Vs. 37.1+/-3.1 nmol/ml, p= 0.001) were significantly lower in the ovnweight group. The oral glucose tolerance test before/after pregnancy showed increased frequency of abnormal glucose metabolism, in both of the non-obese group (38.8%, 26,9%) and the obese group (64.2%, 53.9%) compared with normal population. CONCLUSION: It is thought that in the normal weight group with polycystic ovarian syndrome androgen production is stimulated in the theca cells by abnormally high LH secretion, while in the overweight group the hyperinsulinemia state which decreases the SHBG and IGFBP-I, lead to increase biologically active hee androgens and IGF-I and increase insulin binding to its receptor. And during/before pregnancy, women with PCOS showed that incidence of abnormal glucose metabolism was significantly increased in both of non-obese and obese groups.
