Background : It has been suggested that thrombospondin (TSP) is a p53-dependent negative regulator of tumor angiogenesis. TSP expression and localization in hepatocellular carcinomas (HCCs) and its association with overexpression of p53 protein were investigated. Methods : TSP-1 and -2 expressions were examined in 40 HCC specimens by immunohistochemical staining and in 4 HCC cell lines by Western blotting. In addition, p53 protein expression and microvessel density (MVD) were correlated with the TSP expression. Results : Strong immu- nopositivity for TSP-1 was observed in fibroblasts, vascular endothelial cells, and some vas- cular smooth muscle cells of the stroma in 18 cases (45%), and in tumor cells in 3 cases (7.5%) of 40 cases of HCC. Immunoreactivity for TSP-2 was observed in only the sinusoidal lining cells of the tumor in 15 cases (46%), and in tumor cells in 2 cases (6%) of 32 cases of HCC. TSP-1 expression was inversely correlated with MVD (p=0.028), but TSP-2 expression did not show any correlation with MVD. Although p53 was overexpressed in 17 cases, there was no significant correlation between TSP and p53 expressions. None of the HCC cell lines expressed TSP-1 or -2. Conclusions : These findings indicate that TSP-1 is mainly derived from nonparenchymal cells, and may decrease tumor angiogenesis in HCC.

Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28GST plays important roles in phase II defense system and physiological roles in worm fecundity of C. sinensis.

In cholangiographic techniques, the close relationship between choledochal cyst and anomalous union of pancreaticobiliary duct has attracted medical attention. There have been rare cases in which the papilla of Vater was found in a position other than its normal position, and such cases have been reported sporadically. However, such cases are interesting in the anatomical context. In this review, we present our experience of choledochal cyst in a 30-month-old boy in whom the papilla of Vater was positioned in the third portion of the duodenum.

Aconitine is a main component of Aconitum carmichaeli, a Chinese herb known to be effective for
arthritis and neuralgia. Many senior citizens consume the herb as a folk remedy. Aconitine-associated
cardiogenic toxicity has been observed but aconitine-induced cerebrovascular event has not been
reported so far. We report two elderly patients who became unconscious and showed neurological
dysfunction soon after ingesting aconitine for pain control. We speculate that the aconitine induced
cardiac arrhythmia. This resulted in cardiogenic emboli formation with subsequent large territory
cerebral infarction.

Fatty tumours are,the most common soft tissue tumours whereas they are among the rarest tumours in bone. Dahlin quoted an incidence of 1 in 1, 000 of all bone tumours, and fatty tumours in bone are almost single intraosseous lipoma and of four types; I. Soft tissue lipomata or liposarcomata, secondarily affecting bone. 2. Parosteal lipomata. 3. Intraosseous lipomata. 4. Liposarcoma of bone. Here we report a case of multiple intraosseous lipomas in a 23 year old woman.

Ten cases of fracture of the carpal scaphoid analysed clinically and treated by admission at Department of Orthopedic Surgery, National Police Hospital during the period of 1975 to 1980. The results were summerized as follows: 1. The mode of the injury were consist of 3 in football game, 2 in judo, 2 in army training and 1 in fallen from height, 1 in slipping down, 1 in direct blow and almost falling down by outstretched hand. 2. Of the 10 cases, there were 9 male and 1 female patients. This result showed marked predominence of male over female patients and most commonly occured between 20 and 29 of age. 3. In 8 cases, the fracture was found on the waist of the carpal scaphoid. 4. Nonunion of the carpal scaphoid were noticed in 8 cases. 5. 2 cases of the recent fracture, there were appeared by rechecking X.-ray after 2 weeks. 6. The good results were obtained by bone graft according to method of Russe.
