1.Immuno-diffusion and complement-fixation test in paragonimiasis of cat.
The Korean Journal of Parasitology 1969;7(3):160-165
In order to observe the complement fixation test and immuno-diffusion test of paragonimiasis, the sera taken at 10 days intervals up to 150 days from cats infected with Paragonimus westermani were examined by the above two immunological methods. The resultant findings were as follows: The complement fixation test showed positive reaction 20 days after the infection with 20 metacercariae, and 40-50 days after the infection with 10 metacercariae. The highest titer was observed 110 days later following the acceleration at 80 days later. In immuno-diffusion test, one are appeared 30 days after the infection with 20 metacercariae, but 60 days after the infection with 10 metacercariae. However, more than two arcs were observed since 70 days after infection. A relatively wide band appeared by the antigens of Fresh worm material and Somatic material. But relatively clear precipitin lines were observed in the diffusion test with V.B.S. antigen, increasing to 3-4 arcs after 110days. In general, complement fixation test showed earlier and higher sensitive reaction than immuno-diffusion test, and was considered to be more valuable method forr immunological diagnosis.

PURPOSE: To describe the MR features of intraspinal cysticercosis. MATERIALS AND METHODS: Medical records and MR images of four cases of intraspinal cysticercosis were retrospectively reviewed. The MR findings were described with regard to the location and signal intensity of the lesions, contrast enhancement, presence or absence of associated intracranial cysticerci, and other findings. RESULTS: There were three cases of subarachnoidal form and one case of intramedullary form. Cysticerci of subarachnoidal form in three cases were located in retromedullary space at C2 level, anterior to cord at C1 -C6 levels, and lumbosacral area, respectively. The signal intensities of the lesions were same as those of CSF. Localized arachnoidal enhancement was found in all three cases. In one case there was a large area of high signal intensity within the spinal cord on T2 weighted image suggesting either ischemia secondary to vascular compromise or inflammatory edema. All of these three cases accompanied intracranial cysticercosis. Intramedullary cysticercosis in one case was shown as a single I cm cystic lesion at C2 level, which showed hypointense signal on T1 weighted image, hyperintense signal on T2-weighted image, and signet-ring-like enhancement. This lesion did not accompany intracranial cysticerci. CONCLUSION: lntraspinal cysticercosis manifested as single or multiple cysts within either spinal cord or subarachnoid space, and were frequently associated with arachnoiditis.

PURPOSE: We report the results of embolization in 42 cases of brain arteriovenous malformation and discuss the technical problems. MATERIALS AND METHODS: Flow-guided microcatheter for the superselection of the feeding arteries and nbutyl cyanoacrylate as an embolic agent were used. Wire guided microcatheter and microparticle were used in two exceptional cases. As preembolization functional evaluation, 30--50mg of thiopental sodium solution was injected into the feeding arteries through superselected microcatheters in 40 cases with supratentorial lesions. RESULTS: There was no local arterial complication by injection of thiopental solution. Embolization caused a permanent neurologic deficit(mild to moderated hemiparesis) in 2 patients (4.8%) by a reflux of embolic agent or probable spasm of main arterial trunk. In 8 patients(19%), the AVMs were completely obliterated and 25 patients(60%) showed anglographic obliterations of 50--90% of the lesions. Embolization induced venous occlusion was demonstrated at post-embolization angiography in 6 patients, and 3 patients of them showed delayed and transient neurologic deficits. CONCLUSION: Embolization of cerebral AVM can be performed effectively and safely by a superselective method and appropriate functional evaluation. Superselective thiopental sodium injection is a safe and reliable test for the evaluation of local brain function before embolization.

In 56 breast cancer tissues (infiltrating ductal carcinoma) with a clinical follow-up period of more than 5 years, positivity of estrogen receptor(ER) by enzyme immunoassay and expressions of bcl-2 and p53 oncoproteins by immunohistochemistry were evaluated. The purposes of this study were to determine prevalence of bcl-2 and p53 in breast cancer, the interrelationship between expression of the proteins and estrogen receptor, correlation between histologic grade and the expression of the tumor-related oncogenes, and to explore the biologic bahavior of breast cancer (lymph node metastasis, recurrence rate, and survival) via expression of bcl-2 and p53. Twelve of 56 (21.4%) carcinomas were bcl-2 positive, and seventeen (30.4%) were p53- positive. Eleven of 12 bcl-2 positive tumors (91.7%) were ER-positive, and bcl-2 expression was significantly associated with ER-positivity(P=0.043). Seven of 36 ER-positive tumors (12.5%) were p53 positive, and p53 expression was inversely associated with ER-positivity(P=0.006) significantly. The bcl-2 protein expression showed a significant relationship to low histologic grade of tumor (P=0.0002), and an almost significant relationship to lower recurrence rate (P=0.09). The p53 protein expression showed a significant relationship to high histologic grade of tumor (P=0.002) and an almost significant relationship to lymph node metastasis (P=0.09). Also an almost inverse relationship between bcl-2 and p53 was demonstrated (P=0.057). The bcl-2 expression had a tendency to be associated with longer patient survival(P= 0.09), but p53 immunoreaction was found not to be associated with shorter patient survival(P=0.16). These results provide further evidence that higher incidence of bcl-2 expression is correlated with higher incidence of ER and lower grade of tumor, while p53 expression is correlated with lower incidence of ER and higher grade of tumor. In conclusion, although the biologic function of bcl-2 protein is not yet well understood in breast cancer, our results suggest that bcl-2 and p53 oncoproteins might play significant roles in estrogen receptor and development of breast cancer. But their prognostic significance could not be determined; our results are 'not significant' but 'almost significant'. Thus, contribution of bcl-2 and p53 immunohistochemical phenotyping of breast cancer with ER to the clinical management need verification in larger series.

In spite of technical advances in neuroradiology, neuroanesthesiology, and microneurosurgery, the treatment of giant aneurysms remains problematic. Between 1983 and 1995, the authors encountered 42 consecutive cases of giant aneurysms, and this study focuses on their clinical manifestations, management, and outcome. The patients' ages ranged from 5 to 73 years, with peak incidence in the sixth decade ; the male to female ratio was 12 : 30. The follow-up period was from 2 to 110(mean, 36) months. The most common presenting symptom was a mass effect found in 22 patients(52%), followed by subarachnoid hemorrhage in 16(38%). Thirty patients underwent a surgical or interventional radiological procedure, comprising direct neck clipping(n=13), proximal clipping(n=7), detachable balloon occlusion(n=4), wrapping(n=3), trapping(n=1), and partial clipping with thrombectomy(n=2). The mortality rate was 16.7% and the morbidity rate, 40% ; the most common postoperative complication was distal cerebral infarction. At the last follow-up, 22 patients(73%) were able to perform daily activities without assistance. In this clinical study, the authors reviewed general aspects of the treatment of giant aneurysms. In conclusion, treatment of giant aneurysms should-for best results-be tailored to patients' individual requirements, determined after thorough examination. Despite advanced neurosurgical techniques, morbidity and mortality rates remain high.

Eczema herpeticum occurred in a patient with pemphigus foliaceus and esophageal cancer. The patient's initial skin lesions composed of large flaccid bullaes showed subcorneal bullae with typical acantholytic cells. Subsequent grouped small vesicles appeared widely on the erythematous base were diagnosed herpes simplex virus infection by Tzanck smear and histopathological findings. The patient died one week after the development of the widespread herpes virus infection.
