In order to determine the intensity of infection with the encysted larvae of Metagonimus yokogawai among Plecoglossus altivelis, sweetfish, caught at the rivers in Kyungpook Province, Korea were examined in the period from July to October, 1976. The data were compared with the results obtained from Tribolodon hakonensis, the sea-run dace, caught at the river Hyungsan in the Province. A total of 128 Plecoglossus altivelis were examined. All the fish were infected with the metacercaria of Metagonimus yokogawai. The metacercarial rate for the fluke in the flesh was higher than the rates in the fins and scales. The average number of larvae per sweetfish was 4,333, compared with the average of 1,541 from the sea-run dace. It was found that the highest number of encysted larvae was found in the flesh of sweetfish, whereas it was encountered on the scales of sea-run dace. In the distribution pattern of the cysts, there was no relationship between the size of fish and the intensity of infection.

BACKGROUND: In epidermolysis bullosa acquisita, it has been recognized that there exists heterogeneity in the clinical and serologic/immunopathologic features. OBJECTIVE: We examined patients with epidermolysis bullosa acquisita to see if there were any associated clinical and serological features which may predict disease activity or prognosis in the disease. METHODS: Clinical and some serologic features were compared. between 2 groups of patients with epidermolysis bullosa acquisita; one with complete remission of the symptoms and signs of the disease for more than 2 years and the other group with persistent disease activities of longer than 5 years.

The blow-out fracture can be reconstructed by various autogeneous and alloplastic material. Particulate, nonresorbable hydroxyapatite is currently one of the choice of implant material available for reconstruction of blow-out fracture. Hydroxyapatite is radiopaque ceramic, physically and chemically similar to enamel and cortical bone. It is a biomaterial derived from natural corals to use as a bone graft substitute. And we looked into the clinical usefulness of 2 type of hydroxyapatite with their advantages and disadvantages in reconstruction of blow-out fracture. 183 patients with blow-out fracture who underwent surgical reconstruction with two types of hydroxyapatite from March 1933 to July 1977 have been analyzed the results of surgical reconstructions, and have been followed up for more than a year. And the condition of formerly inserted hydroxyapatite was observed in the patients who needed 2nd surgical reconstruction due to the enophthalmos. The disadvantages of hydroxyapatite are fragility, size and contour limitations. In spite of these demerits, hydroxyapatite can be one of the prospective materials to reconstruct orbital floor. Through the clinical experiences for 5 years, we have not found any of complications of exposure, infection, and foreign body reaction. Low rates of diplopia, limitation of ocular movement, and enophtalmos was observed. Hydroxyapatite was well adherent to adjacent orbital bone in most patients who needed secondary reconstruction for enopthalmos. In conclusion, our study shows that the availability of hydroxyapattite in reconstruction of blow-out fracture is recommendable, with low complication rates. Hydroxyapatite important appears to be well tolerated, and provides useful alloplastic prosthesis with few problems in reconstruction of blow-out fracture.

BACKGROUND: Peripheral nerve injury may produce a syndrome consisting of spontaneous pain, allodynia and hyperpathia. Cholinesterase inhibitors are known to have an antinociceptive effect in hot plate and tail flick tests and to be mediated by spinal muscarinic system. The purpose of the current study was to determine the effect of intrathecally (i.t.) administered edrophonium and neostigmine on the touch-evoked allodynia and to identify the antagonism of antiallodynia in a rat model of neuropathic pain. METHODS: Sprague Dawley rats were prepared with tight ligation of left L5/L6 spinal nerves with 6~0 black silk and chronic lumbar intrathecal catheters. After obtaining the baseline hindpaw withdrawal scores, edrophonium (3~100ug) or neostigmine (0.3~10ug) was administered intrathecally. Tactile allodynia was measured using von Frey filaments and allodynic threshold was calculated by updown method. Motor dysfunction was assessed by observing righting/stepping reflex responses and abnormal weight bearing. To examine the reversal of antiallod ynia, muscarinic receptor antagonist atropine (10ug) or nicotinic receptor antagonist mecamylamine (10ug) was injected intrathecally 5 min. prior to injection of edrophonium or neostigmine. RESULTS: I.t. edrophonium and i.t. neostigmine produced a dose dependent antagonism of allodynic state but had moderate to severe effect on motor weakness at doses of 3 and 10 g of neostigmine. Pretreatment with i.t. atropine yielded a complete antagonism of antiallodynia in both drugs, but i.t. mecamylamine did not significantly reverse incresed allodynic threshold. CONCLUSIONS: These experiments suggest that i.t. edrophonium or i.t. neostigmine produces a dose dependent antagonism on touch-evoked allodynia at the spinal level and this antagonism is likely due to spinal muscarinic system.

We compared the efficacy of each modality of treatment group in reducing the frequency of coronary artery abnormalities and change of clinical courses in children with Kawasaki disease in the children of 81 cases who were admitted in pediatric department of Yeungnam University Hospital from September 1985 to August 1990. Group A (37 cases)-aspirin alone, Group B (44 cases)-intravenous gammaglobulin (400 mmg/kg/day) for 5 consecutive days, plus aspirin. We studied the frequency of echocardiographic abnormalities, the duration of fever, and changes in the total white blood cell counts, platelet counts, ESR and CRP value at 1, 2 and 3 weeks of the illness and compared the results between the two groups. The results were as follows. 1) There was no significant intergroup difference in age and sex ratio. 2)The duration of the febrile period after the initiation of the therapy was significant shorter in group B (2.5±1.2days) than in group A: (5.2±3.5 days) (p<0.01). 3) No significant difference was noticed in the WBC and platelet counts in two groups as measured at admission day, 1 and 2 weeks of the illness, however, at 3weeks of illness significant difference was noted. 4) The CRP values measured at 1,2 and 3 weeks after treatment were significantly lower in group B (2.42±1.8, 2.00±1.2, 1.16±1.0) than in group A (7.22±5.3, 5.25±3.9, 1.85±1.2) respectively (p<0.01). 5) In 2D-Echocardiogram, coronary artery dilatation was more frequent in Group A than in Group B at 6month of illness (p<0.01). In conclusion, intravenous gammaglobulin therapy was effective in the shortening of the duration of fever and in the anti-inflammatory action and somewhat effective in prevention of coronary artery aneurysm.
