The maintenance of balance between water and electrolyte is essential for keeping the lens transparent. The outflow of the Na+ ion from the membrane and inflow of the K+ ion both of which are sustained by the Na+ - K+ - ATPase, play an important role in maintaining this balance. In this study, by comparing the lens Na+ - K+ - ATPase activity in Spontaneous Hypertensive Rat(SHR) and Sprague-Dawley Rat (SDR), we determined the significance of increase in blood pressure and the change in the enzyme activity after control of blood pressure by administration of Inderal, an anti-hypertensive drug. The Na+ - K+ - ATPase activity was significantly lowered(P<0.01) in the lens of SHR compared to that of SDR. The longer the anti-hypertensive drug was administered and then controlled the blood pressure, the higher the recovery rate of the lowered Na+ - K+ - ATPase activity of SHR, rising up to about 50%. From the results of this study, it is suggested that the activity of lens Na+ - K+ - ATPase may be reversibly recovered after blood pressure control, and that the pathogenesis of high blood pressure-associated cataract may be partially prevented by controlling the blood pressure.

Patients with chronic lateral ankle instability often experience a range of associated injuries. The well-known comorbidities include intra-articular pathologies (osteochondral lesion, soft tissue or bony impingement, and loose body), peroneal tendon pathologies, neural injuries, and other extra-articular pathologies. Surgeons should have a high index of suspicion for these associated pathologies before operative intervention, correlate the clinical findings, and plan the treatment. Despite the restoration of ankle stability following ligament repair or reconstruction surgery, a high prevalence (13%~35%) of postoperative residual pain has been reported. This pain can negatively affect the clinical outcomes and patient satisfaction. This study examined the causes of persistent pain after surgical treatments for chronic ankle instability.

Chronic Achilles tendon rupture is likely to result in functional impairment in gait and sports activity. The presence of a large defect secondary to retraction of the tendon ends, atrophy of the calf muscles, and vulnerable vascularity of the soft tissue envelope make it a challenging problem to treat. Surgical reconstruction aims to restore the length and tension of the gastrocnemius-soleus complex. Various surgical treatment options have been described, depending on several factors, including residual gap size after scar tissue removal, remaining tissue quality, and vascularity. Despite good results being reported, there is a lack of high-level, evidence-based clinical guidelines available to select the first-line surgical procedure. This paper overviews the current available surgical options for patients with chronic Achilles tendon rupture.

Since the first attemt of internal fixation not much more than a century ago, implants have come to play an important role in orthopaedic surgery. Yet little has been reported about complications which may result from implant surgery. During the period of May 1980 to April 1984, 32 cases of fixation failures were treated in the Department of Orthopaedic Surgery, Hallym College, Kang Nam Sacred Heart Hospital and results were obtained as follows: 1. The most common area involved femoral shaft, but the highest rate was distal femur. 2. The most common period of failure was between 2 to 4 months postoperatively. 3. The leading cause of failure was remaining defects at fracture site. 4. The authors recommend accurate reduction of fracture and bone graft, if necessary, adequate immobilization postoperatively and co-coperation of patient to avoid failure of implant.
