Calcific myonecrosis is a rare late post-traumatic condition in which an entire single muscle is replaced by a fusiform mass with central liquefaction and peripheral calcification. The compartmental syndrome is suggested to be the underlying cause. We report a case of 70 year-old man whose right tibialis anterior and extensor hallucis longus muscle were replaced by calcific myonecrosis and treated with en-bloc resection & tendon reconstruction.

We had a female patient with soft tissue tumor involving large portion of Achilles tendon. After resection of tumor, Achilles tendon was reconstructed using an allogenic human fascia lata manufactured by Pfrimmer-Viggo. EMG findings on postoperative 8 months show marked improvement of function of medial and lateral gastrocnemius muscles. Biopsy specimen of fascia lata allograft, which was acquired during TAL 8 months postoperatively, shows myxoid degeneration, a few lymphocytic infiltration and some foreign body giant cells. Functional, histologic and EMG findings suggest that human fascia lata allograft could be used to bridge defect of Achilles tendon being resected during tumor surgery.

Suture microvascular anastomosis is time-consuming and tedious and demands long and continuous training. The Unilink instrument system is a fast and simple method to achieve high patency rates without long and continuous training in the anastomosis of small vessels. The author experimentally studied the carotid arteries and facial veins of 14 rabbits with an average weight of 1900 gm using the unilink apparatus. A total of 27 arterial and venous anastomoses were performed. We examined the postoperative patency at immediate, 2 weeks, and 8 weeks. The results were as followings; 1. All anastomosed vessels were fully patent just after operation and at 2 weeks(100%), but one of the arterial anastomosis was thrombotized at 8 weeks(90%) 2. The mean time for completion of the anastomosis were 8.5 minutes(range 6-15) in arteries and 6.2 minutes.(range 4-10) in veins. 3. The cases having partial obliterations were 3 cases(15%) under the operating microscope. 4. At the histological examination, the thickness of vessel wall was decreased due to moderate atrophy of the media and mild degree of nonspecific chronic inflammation was seen around the unilink apparatus. 5. A case of the arterial anastomosis was released with acting out at 15 minutes after operation, and a case of arterial anastomosis showed complete oblieration at postoperative 8 weeks. 6. The important factors in the technical problems were the proper selection of the ring size and optimal fitting between two rings. The Unilink method provides a very safe, fast, and simple way to perform microvascular anastomoses.

The experiments of this study was performed to investigate the effects of sulfur dioxide on the changes of glycoconjugates of respiratory system of the rat. Sprague -Dawley male rats weighing about 200 ~250g were divided into a control group and SO2 exposed groups. Again SO2 exposed groups were divided into 10 ppm, 25 ppm, 50 ppm, 100 ppm and 200 ppm subgroups according to concentrations of SO2 and each SO2 exposed groups were divided into 1, 3 and 6 hours groups. For the histological changes, H -E(hematoxylin -eosin) and PAS(periodic acid Schiff) staining were used and to investigate the change of sugar residues of glycoconjugates, biotinylated lectins(DBA, SBA, PNA, BSL -1, sWGA, UEA -1, LCA and Con A) were applied. Generally, the effects of SO2 on the rat nasal respiratory region were more serious at the high concentrations. Moreover, as the exposed time was longer even at the low concentrations, the effects of SO2 were similar to those of high concentration. Compared with all SO2 concentrations, the longer exposed time was, the more serious the effects of SO2 were. In the SO2 exposed groups the binding of PNA, RCA -1 and UEA -1 of cilia in the nasal septal respiratory epithelium tended to increase in the 10 ppm and 25 ppm SO2 exposed groups but it tended to decrease in the 100 ppm and 200 ppm SO2 exposed groups. In the cytoplasm of columnar cells of nasal septal respiratory epithelium, Con A binding increased in all the SO2 exposed groups. In the goblet cells DBA, SBA, PNA, RCA -1 and UEA -1 binding increased remarkably in the 50 ppm SO2 exposed groups but it decreased largely or disappeared in the 100 ppm and 200 ppm SO2 exposed groups. The binding of SBA, PNA, BSL -1, UEA -1 and Con A in the intraepithelial mucous cells which were not detected in the control group, increased in the 25 ppm and 50 ppm SO2 exposed groups while it tended to decrease in the 100 ppm and 200 ppm SO2 exposed groups. The binding of sWGA increased according to the concentrations of SO2 were higher and exposed times were longer. In the superior nasal septal gland, the binding of PNA increased in the 50 ppm and 100 ppm SO2 exposed groups and that of Con A increased in the 25 ppm and 50 ppm SO2 exposed groups. In the inferior nasal septal gland, except for LCA, the binding of the other lectins increased remarkably in the 25 ppm and 50 ppm SO2 exposed groups but it tended to decrease in the 100 ppm and 200 ppm SO2 groups. In the mucous duct cells, the reaction of PNA and RCA -1 increased compared with that of the control group. And the reaction of BSL -1 and UEA -1 increased in the lower concentrations of 50 ppm SO2 exposed group but it decreased in the 100 ppm and 200 ppm SO2 exposed groups. The binding of Con A increased in the 25 ppm and 50 ppm SO2 exposed groups. Consequently, from the results above mentioned that SO2 affected serious changes on glycoconjugates metabolism in the nasal cavity.

Appendiceal mucocele is a cystic dilatation of the appendiceal lumen with mucus, which may be caused by either benign or malignant diseases. In this report, five cases of appendiceal mucocele are reported, three of which had a preoperative diagnosis of mucocele, whereas the others were found incidentally during the operation under the diagnosis of intussusception and periappendiceal abscess. All five patients underwent surgical resections, including one ileocecal resection and four right hemicolectomies. Histopathology revealed a mucinous cystadenoma in four cases, and a mucinous cystadenocarcinoma in one. There was no disease-related death during 18 months of follow-up.
