Tentative diagnosis of meniscal pathology is very helpful for the successful operative management including arthroscopy. Conventional arthrography has long been used to meet this purpose, but it has some limitations due to complex views and some difficulties in imaging the whole anatomical structures. Recent diagnostic advancement produced post-arthrographic HRCT and MRI for the compensation of these problems of conventional arthrography. Arthrography and post-arthrographic HRCT has been carried out on 49 knees in 43 patients. 38 knees among them could be confirmed by arthroscopy and following results were obtained. 1. Diagnostic accuracies of post-arthrographic HRCT for medial and lateral meniscal injuries of knee were 94.7% and 92.1% repectively. 2. Shape, contour of torn meniscus and the relationships between the torn fragments were better demonstrated with HRCT. 3. Horizontal tear could also be suspected by HRCT. 4. Peripheral detachment could be differentiated with synovial recess on the HRCT, especially in the reformat view, but was more clearly visible in arthrography. 5. Arthrography and HRCT can be used as a good complementary study for the evaluation of meniscal injuries.

The new method is described of extracting various types of cataracts intracapsularly by means of a pencil-shaped metal instrument, named Krwawicz's model cryoextractor. This is refrigerated in a mixture of dry ice and methyl alcohol so that when the ice-coated tip is applied to the lens, the capsule and the underlying cataractous masses adhere firmly to its ball-shaped end and an easy intracapsular extraction is ensured. Fifty extractions of various types of cataracts have been performed by this method. In 49 cases the cataract could be extracted intracapsularly. In only one case did the capsule rupture but it was possible to remove the capsule and lens mass almost completely. The results of the fifty extractions by this method are given.

Lichen striatus usually occurs in a solitary and unilateral fashion. Its multiple and bilateral distribution is a very rare finding. We report two cases of multiple lichen striatus. The first case is a 3 year-old boy, whose skin lesions were distributed bilaterally on both upper arms and buttock. The second case is a 6 year-old girl whose skin lesions were two separated linear lesions from left chest and left upper back to left arm.

Recently the esthetic demands of clinicians and patients made the surgeon try to regenerate bone defects and gingival tissue after extraction. For that, many surgical methods were used and socket preservation have been evaluated simple, effective and good prognosis in the implant placement. Bone grafting was one of the methods for socket preservation. This study was to evaluate the histologic view of the effects on healing of the extraction sockets when deproteinized bovine bone mineral and tetracycline coated deproteinized bovine bone mineral was implanted 1. In control group, at 4 weeks after implantation, the extraction sockets were filled with connective tissue. And after 8 weeks, osteoblasts were observed in newly formed trabecular among the fibrous connective tissue in the extraction sockets. 2. In experimental 1 group, there was connective tissue and new bone trabecular around newly formed woven bone at 4 weeks. And many osteoblasts were observed in various direction at 8 weeks. 3. In experimental 2 group, there was a lot of new bone made around the bone powder after 4 weeks, and the thicker bone trabecular, lamellar bone and irregular osteoblasts arrangement were observed at 8 weeks. From the results of this study, tetracycline coated BBP would be better than the other groups in the lamellar bone formation and be faster in the bone formation rate.
