Prevalence of sparganum in the frog (Rana nigromaculata) was surveyed in Dae-jeon city and in suburbs of the city, Chungnam Do. 39 (3.9 per cent) out of 1,011 frogs were infected with the worm, and the highest prevalence rate of sparganum was found the frogs from Shintanjin area(11.3 per cent). Infection rates of sparganum were observed due to the body weight and sex of frogs. The highest infection rate of frogs, the body weight of 50 gms or more, showed 30.3 per cent(female: 41.7 per cent, male: none), on the other hand, no worm was found in young frogs(less than 10 gms). Distribution of sparganum in the frogs was recorded and 82.6 per cent of worms were distributed in the femoral intermuscular connective tissues of the hind legs. Among those infected frogs, number of worm burden was one to five worms, and 53.3 per cent of frogs were infected by only one worm.

Sex cord tumor with annular tubules (SCTAT) is a rare ovarian neoplasm which usually occurs in two forms. In patients associated with Peutz-Jeghers syndrome, the tumors are usually small, bilateral or multifocal, and show benign clinical course. However, tumors from patients without the syndrome are often large, usually unilateral, and rarely show malignant behavior. Serous surface papillary carcinoma (SSPC) is an aggressive neoplasm which involves peritoneal linings, including ovarian surface. Recently, we encountered a case of an unusual combination of SCTAT and SSPC in the ovary of a 55-year-old Korean woman presented with abdominal distention for one year. Systemic review and physical examination were within normal limit, except for abdominal discomfort and distention. There was no stigmata of Peutz-Jeghers syndrome in all diagnostic examinations, including gastroscopy and colonoscopy. Pelvic computed tomography showed adnexal mass with multiple peritoneal nodules. Exploration revealed uterine and ovarian surfaces covered with multiple, yellow-white papillary nodules. However, the sizes of both ovaries were within normal limit. Typical serous papillary carcinomas were identified in nodules from peritoneum and ovarian surfaces. Well-circumscribed columnar epithelial cell nests composed of ring-shaped tubules encircling hyalinized basement membrane-like materials were found in the ovary away from serous surface papillary carcinoma.

OBJECTIVE: Recently, we have demonstrated that embryonic ventral spinal cord motor neurons(ESMNs), transplanted into the distal stump of the axotomized tibial nerve, can grow into the denervated gastrocnemius muscle and form neuromuscular junctions. Our interest in study was to see whether these newly formed neuronal connections are physiologically active, and to electrophysiologically characterize the reinnervated motor units. MATERIAL AND METHODS: Three to eight weeks after transplantation rats were prepared for electrophysiological recording. Motor unit (MU) action potential and gross EMG were monitored. In eleven out of sixteen transplanted animals single unit and gross EMG were recorded after electrical stimulation of the transplant site. Total of 63 motor units were analyzed for their stimulus threshold (ST), latency and stimulus intensity, which is required to produce maximum firing. RESULTS: ST intensities activating MUs were significantly higher in transplanted animals than in controls. Maximum firing of MUs occurred at less than 1.2×T in the control but greater variation was observed in the transplanted animals ranging from 1.1×T to 1.6×T. No significant differences were found in the latencies of MU's firing following stimulation. MU firing was reversibly blocked by infusion of succinylcholine. CONCLUSION: we characterized the temporal, morphological and electrophysiological parameters of denervated skeletal muscle reinnervated by dissociated grafts of embryonic ventral spinal cord cells. MUs reinnervated by the embryonic motoneuronal transplant were physiologically active, with some properties similar to the MUs of the normal.
