BACKGROUND: Angiotensin convertiong enzyme inhibitors have been shown to exert favorable effects on the left ventricular remodeling process associated with ventricular dilation after coronary occlusion. However, the effects of such therapy on global and regional left ventricular remodeling after coronart artery reperfusion have not been characterized, nor have such effects been assessed after exercise training. METHODS AND RESULTS: Female Sprague-Dawley rats(n=80) were randodmized into 4 groups at 5 days after 45 minutes of left coronary artery occlusion followed by reperfusion. Animals completion the experiment included : Untreated Sedentary group(n=20), Untreated with Swimming Exercise group(n=21), Captopril Treated Sedentary group(n=18) and Captoril Treated with Exercise group(n=21). At 3 weeks after randomization, global and regional morphologic changes of the left ventricle(LV) were examined from mid-ventricular transverse slices which were perfusion-fixed at a constant aortic pressure of 60mmHg and a left ventricular cavity pressure of 10mmHG. At rest and during exercise, compared to untreated rats, the captopril treated animals showed significantly decreased LV weight/tibial length ratio(LV/TL)(p<0.01),increased LV cavity area and dimension(both p<0.01), decreased total myocardial area and noninfarcted area(both p<30.001) and reduced wall thicknesses in the noninfarcted and infarcted regions(both p<0.001). Compared to treated and untreated dsedentary rats, exercise significantly increased LV/TL(p<0.05) and epicardial and endocardial areas in the infarcted zone(both p<0.05) and decreased transmurality(p<0.01). Exercise decreased LV cavity area in the captopril treated groups(42.3+/-10.4 vs. 40.4+/-6.0mm2),whereas exercise increased LV cavity area in the untreated groups(33.5+/-8.9 vs. 39.1+/-6.2mm2)(p<0.05). CONCLUSION: These findings provide evidence in rats for evidence in rats for exaggerated left ventricular dilation and supperssion of compensatory myocardial hypertrophy globally and in the infarct zone with 3 weeks of captopril treatment following coronary artery reperfusion with acute nontransmural myocardial infarction. In addition, the effects of captopril on LV dilation and suppression of global and regional hypertrophic response were partially reversible by swimming exercise.

Authors carried out an investigation of the helminthic parasites of the wild birds in Korea. Most wild birds were collected from Kyoung Sang Do, Kyoung Kee Do and Seoul area from September 1970 to March 1973. A total of 70 wild birds, 19 species were examined, which comprised as follows; 10 Anas platyrhynchus, 10 Anas fulicata, 4 Anas poeciolorhyncha zonorhyncha, 8 Anser albifrone albifrone, 5 Anser cygonopsis cygnoid, 10 Aythya fuligula, 6 Gallicrex cinerea, 2 Porgana fusca, 2 Phisianum calichius korponri, 4 Sterptopilla orientalis, Podiceps cristatus, Larus crasirotatus, Malantta fusca, Garis artcus, Buetes buteo, Egretta alba, Starmus philpiens, Bombycilla granulus. Trematode parasites found from six species of the wild birds. Echinostomatidae has been found from intestine of the Anas platyrhynchus platyrhynchus, Anas poeciolorhyncha zonorhyncha, Anas fulcata. Notocatylus attenuatis found from intestine of the Podiceps cristatus, Anas fulcata. Catylurus japonicus was found from rectum of the Anas platyrhynchus platyrhynchus, Anas poeciolorhyncha zonorhyncha.

Melorheostosis is a rare entity while causes pain and stiffness in a limb and has an unknown etiology. It is characterized by roentgenographic appearance of melting wax dripping down one side of a candle along the major axis of long bone. The present case represents a melorheostosis of the left tibia accompanied by synovial chondromatosis in the left knee. Good result was obtained by arthrotomy of the left knee and removal of the bony masses in the joint.

Extra-capsular synovial chondroma is a rare condition in which metaplastic cartilaginous mass is formed by the cartilage nodule within the synovial connective tissue break through the joint capsule and continue to proliferate. The authors have experienced a case of giant extracapsular synovial chondroma, affecting the knee joint of 54 years old woman. A case of giant extra-capsular synovial chondroma is reported with brief review of literature.

There are many procedures for treatment of injuries of acromioclavicular separation but there are still con- roversies concerning the best management of these injuries. With this in mind, we treated surgically 22 cases of acromioclavicular separation of which 3 cases were old type 2 and 19 cases were type 3 in the department of orthopaedic surgery, Eul Ji General Hospital from March 1977 to darch 1982. The results were as follows: l. Of 22 cases, 21 cases (95.5%) were male with peak incidence in the 3rd and 5th decades (90.9%). 2. The most common causes of the injuries were traffic accidents (63.6%) and followed by falling from height (22.7%). 3. The diagnosis in type 2 and type 3 injuries is based on the clavicular displacement and instability at the acromioclavicular joint. 4. Operative treatment consists of Weaver and Dunn method (54.5%), modified Phemister method (18.2%), Neviaser method (13.0%), Stewart method (9.1%) and modified Henry method (4.5%). 5. The operative procedure in old type 2 and typc 3 injuries is good treatment of acromioclavicular separation.
