1.Effects of Sodium Alginate on the Non-Specfic Defense System of the Common Carp ( Cyprinus carpio L. ).
Korean Journal of Immunology 1999;21(1):71-76
Carp which receive intraperitoneal injections of sodium alginate show a high survival rate after being challenged with Edwardsiella tarda. To elucidate the immunoenhancement by sodium alginate, its effects on the non-specific defense system of carp were investigated. Sodium alginate had little influence either on the activity of the alternative complement pathway or on the phagocytic and respiratory burst activities of head kidney phagocytes (HKP), yet it greatly enhanced the migration of HKP to the peritoneal cavity (the site of injection) and concurrently elevated their phagocytic activity. The number of phagocytes mobilized by sodium alginate was 2 to 50 times greater than that by the well-known peritoneal exudate cell-eliciting agents when injected at the same dose. Accordingly, it is highly probable that the early elimination of challenge bacteria by such mobilized and activated phagocytes was responsible for the high survival rate of the alginateinjected fish. In chemotaxis assays, it was revealed that sodium alginate stimulated sorne leukocyte subpopulation (s) within the peritoneal cavity to produce and/or secrete chemotactic factor (s), while concurrently enhancing the sensitivity of HKP to the factor (s).

Puromycin aminonucleoside (PAN) nephropathy was induced in a group of Sprague-Dawley rat by a single dose of intraperitoneal injection to study an ultrastructural alteration of glomerular anionic sites by stain with polyethyleneimine (PEI) as a cationic probe and to examine whether proliferation of podocytes occur by immunohistochemical stain for proliferating cell nuclear antigen (PCNA). The experimental rats developed proteinuria three days after PAN injection. Electron microscopic studies of glomeruli showed the loss of epithelial foot processes, formation of cytoplasmic vacuoles, microvillous formation and increased numbers of lyso- somes in the cytoplasm of podocytes. PEI method seems to selectively stain heparan sulfate proteogly-can in basement membrane and has been widely used to evaluate the changes of basement membrane in human disease as well as in experimental work. The anionic sites on the basement membrane with foot process fusion were mostly indistinguishable from those seen in control rats, but focal areas of loss or disarray of anionic sites were noted. The anionic sites were not seen on the basement membrane where the overlying epithelium was detached. It is strongly suggested that proteinuria in PAN nephrosis may be primarily due to a glomerular epithelial lesion, leading to focal disarray of anionic sites or focal defects in the epithelial covering of the basement membrane. The loss of anionic s'ites in the basement mernbrane may be resulted partially from the foot process fusion and mostly from the epithelial detachment. The increased numbers of PCNA positive cells after the injection of PAN is suggestive of possibility of podocytic proliferation or regeneration.

OBJECTIVE: To evaluate the effect of IL-10 on development of collagen-induced arthritis, on humoral and cellular immunity and on the endogenous production of IL-10 in DBA/1J mice. METHODS: DBA/1J mice were immunized with chicken type II collagen in Freund s complete adjuvant. Murine recombinant IL-10 was given intraperitoneally twice a week from the day of second immunization (week 3) in doses of 0.002ug, 0. 02ug and 0. 2ug for 3 different groups, respectively. Dexamethasone was injected in one group to suppress the arthritis development and this group was used as negative control group. Levels of anti-collagen antibodies, serum IL-10 and stimulation indices of splenic monocytes to collagen were measured at the end of study. RESULTS: The 0. 02ug IL-10 and 0. 2ug IL-10 treated groups developed earlier and more severe arthritis (week 6 and 8) compared to that of the control group while the 0. 002ug IL-10 group has shown similar course to the control group in terms of incidence and severity of arthritis, At week 10, all groups with or without IL-10 injections developed arthritis with similar degree of severity while dexamethasone group showed far less incidence and severity of arthritis. The serum levels of anti-collagen antibody, IL-10 and spleen monocyte stimulation indices to collagen antigen showed no difference among control group, IL-10 injected groups and dexamethasone injected group. CONCLUSION: This study shows IL-10 could worsen the arthritis in CIA with the dosage used in this study without significant influence on the level of anti-collagen antibodies or stimulation indices of spenic monocyte to collagen.

Pustulotic arthro-osteitis is a rheumatic syndrome of unknovn cause, characterised by an inflammatory osteitis of the sternocostoclavicular region and pustuosis palmaris et plantaris. Although many ases of the disease have been reported in Japan, it, has not been reported in Korea so far. Three cases of pustulosis palmaris et plantaris associated i rith sternocostoclavicular hyperostosis or pustulotic arthro-osteitis are presented.

Homozygous Protein C deficiency is a rare genetic disease with catastrophic and fatal purpura fulminans like or thrombotic complication occurring during the neonatal period. Purpura fulminans is characterized by microvascular thrombosis in the dermis followed by perivascular hemorrhage, necrosis, and minimal inflammation. Laboratory findings are consistent with disseminated intravascular coagulopathy: We report a case of purpura fulminans in a neonate with the findings of disseminated intravascular coagulopathy and an undetectable level of protein C activity, whose parents proved to be heterozygous protein C deficiency.
