ABSTRACT
Objective@#To compare the therapeutic efficacy of the bone marrow aspirate concentrate (BMAC)- platelet-rich plasma (PRP) complex with hyaluronic acid in patients with knee osteoarthritis. Method: Thirty-four patients with knee osteoarthritis participated in this study. Seventeen patients in the study group underwent BMAC and PRP extraction followed by intra-articular injection of BMAC-PRP complex within affected knee. Seventeen patients in the control group underwent intra-articular injection of hyaluronic acid. Knee injury, osteoarthritic outcome score (KOOS), and EuroQol-5D (EQ-5D) questionnaire were evaluated before, one month, three months, and six months after the injection. @*Results@#There were statistically significant temporal differences in total KOOS scores in both BMAC-PRP and HA groups. However, there were no significant group difference in the study period. In the Sports and Recreational Function Scale, there was statistically significant improvement in the BMAC-PRP group compared to the HA group at three months (p=0.041). There were no side effects or complications in both groups. @*Conclusion@#Intra-articular injection of BMAC-PRP showed better functional recovery in the OA at three months and this can be an alternative treatment in terms of functional recovery in the OA in addition to the decrease of pain.

ABSTRACT
The involvement of subaortic structures in the aortic valve endocarditis appears more common than previously recognized. The most common location of the subaortic complications is mitral-aortic intervalvular fibrosa(MAIVF) and the complications may be presented as abscess or pseudoaneurysm. We describe a case of infectious pseudoaneurysm of mitral-aortic intervalvular fibrosa mimicking abscess. In our case, complete AV block was revealed on ECG after aortic valve replacement (AVR). Several days after the first operation, re-do AVR and reconstruction of the MAIVF was performed because of complete AV block and dual fistula complicated by pseudoaneurysm in MAIVF.

PURPOSE: We investigated the inhibitory effects of mitomycin-C (MMC) and 5-fluorouracil (5-FU) on the proliferation of the lens epithelial cells (LECs) depending on time and concentration during the epithelial cell culture using capsular bag model. METHODS: We cultured LECs using capsular bag model after exposure to various time and concentration of MMC and 5-FU. We compared the half coverage time and appearance of posterior capsule by LECs. We examined the proliferative and inhibitory effect on LECs using BrdU immune staining. We observed the morphologic change of LECs on histologic section. RESULTS: Half coverage time of posterior capsule by LEC was 18.2 +/- 3.5 days in control group, whereas 27.5 +/- 3.8 days and 26.8 +/- 4.2 days when treated with 0.2 mg/ml MMC, 50 mg/ml 5-FU for 3 minutes, repectively. The increase of concentration and the exposure time of MMC or 5-FU resulted in the delay of coverage time of posterior capsule by LECs and reduction of BrdU incorporation in the nucleus of proliferating cells. On histologic section, reduction of LECs' multilayering and few cytoplasmic organells were observed. CONCLUSIONS: Using capsular bag model, we found the inhibitory effect of MMC and 5-FU on LECs proliferation depending on the concentration and exposure time. Capsular bag model would be contribute to the study about after-cataract.
