  • Primary pericardial malignant mesothelioma is a lethal and rare cardiac neoplasm of mesodermal origin. Most cases are associated with history of pericarditis with constriction and/or tamponade. Authors experienced a case of primary pericardial malignant mesothelioma in a 55-year old female who had suffered from dyspnea and chest pain. Pericardial nodules revealed intense uptake by FDG-PET scan and confirmed as primary pericardial malignant mesothelioma by thoracoscopic biopsy. Here we report this case with a brief review of the relevant literatures.

Localizations of substance P, CGRP and calcium binding proteins in Korean native goat duodenum (한국재래산양 십이지장의 장관신경계통에 분포하는 Substance P, CGRP 및 칼슘결합단백질 반응세포에 대한 면역조직화학적 연구)

  • The localization of substance P(SP), calcitonin gene-related peptide(CGRP) and three calcium binding proteins, calbindin D-28k(CB), calretinin(CR) and parvalbumin(PA) was immunohistochemically examined in the myenteric and submucous plexuses of Korean native goat duodenum. In the neurons of myenteric and submucous plexuses of duodenum, immunoreactivities of SP, CGRP and CB were confirmed in both nerve cell bodies and fibers. In contrast, CR immunoreactivity was found only in nerve fibers of myenteric plexuses, while PA immunoreactivity was found only in nerve cell bodies of submucous plexuses. In the inner circular muscle layer, dense SP-like immunoreactive fibers were prominent but only a few CGRP-like immunoreactivities were observed. Most of SP- and CGRP-like immunoreactive neurons of both plexuses colocalized with CB. This result showed that SP and CGRP may have a important role for the movement of small intestine. The colocalizations of CB with SP or CGRP in myenteric and submucous plexuses suggest that CB may serve neuromodulatory role for SP- and CGRP-immunoreacted neurons on the movement of intestinal wall.

Retrograde Tracer Studies of Tecto-Reticulospinal Pathway and Dorsal Lateral Geniculate Nucleus on GluR1- and GluR4-Immunoreactive Neurons in the Hamster Superior Colliculus (Tecto-reticulospinal pathway (TRS)와 dorsal lateral geniculate nucleus (dLGN)에서 역행성이동추적물질 이용 햄스터 상구에서 GluR1-, GluR4- 면역반응 신경세포 연구)

  • We recently reported the distributions of AMPA ($\alpha$-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate) receptor subtypes glutamate receptors (GluR) 1 and GluR4 in the superior colliculi (SC) of hamsters with antibody immunocytochemistry and the effect of enucleation on these distributions. We also compared these labelings to those of calcium-binding proteins calbindin D28K, calretinin, parvalbumin, and GABA. In the present study, we investigated whether the GluR1- and GluR4-immunoreactive (IR) neurons are interneurons or projection neurons by injection of the retrograde tracer horseradish peroxidase (HRP) into one of each major ascending and descending pathways of the SC. HRP injections were made into a tecto-reticulospinal pathway (TRS) and dorsal lateral geniculate nucleus (dLGN). Animals were then allowed to recover and to survive for 48 hr before perfusion. Sections containing retrograde-labeled neurons were then treated for GluR-immunoreactivity. HRP injections proved that only a small population of the GluR1-IR cells project into TRS (1.4%) and dLGN (2.6%). However, a large subpopulation of GluR4-IR cells project into TRS (32.7%). The differential compositions of inter/projection neurons, along with our previous studies on the separate distribution of the GluR subunits, its differential co-localization with calcium-binding proteins and GABA, and differential reactions to enucleations, strongly imply the functional variety of the receptor subunits in visual behavior responses.
