Q: Abstract: We are presenting a case history of a patient with advanced Hodgkin's disease, who had secondary involvement of his middle ear. To our knowledge this is the first case report of such clinical presentation where radiation therapy was of good help for bringing about symptomatic relief. Possible routes of spread are discussed and the literature is reviewed.

Q: Abstract: The influence of various medium supplements on Sertoli cell (Sc) monolayer permeability to [3H]inulin and polarized secretion of transferrin (Trf) and androgen-binding protein (ABP) was investigated in a two-compartment culture chamber. Sc from 14- and 18-day-old rats were maintained for 13 days in one of the following media: Modified Eagle's Medium-Ham's F-12 (DFM), DFM plus insulin, epidermal growth factor, progesterone, hydrocortisone, and vitamins A and E (6F), 6F plus testosterone (7F), 7F plus FSH (8F), 6F plus 2% fetal bovine serum (6F2S), 6F plus 5% fetal bovine serum (6F5S). The monolayer permeability to [3H]inulin decreased rapidly during the initial 3-5 days of culture for the Sc isolated from 18- and 14-day old animals, then remained stable in all media except DFM. Morphological examination revealed the presence of tight junctions between neighbouring Sc in both age groups, indicating their de novo formation. Secretion of Trf was lowest in DFM and steadily declined. In all other media, Trf secretion peaked on day 5 and remained relatively constant after day 7. Medium 7F only slightly and inconsistently increased the secretion, whereas 8F was always highly stimulatory compared to 6F. Supplementation of 6F with serum resulted in the greatest Trf secretion. In the case of ABP, three different secretion patterns were noted depending on the medium composition; secretion was greatest in the presence of 5% fetal bovine serum. The medium supplements also differentially affected the polarity of Trf and ABP secretion. The ratio of Trf secreted to the outer and inner compartments (OC/IC) was approximately 2.0 in DFM and was not influenced by supplements in 6F, 7F, and 8F. However, in serum-containing media, the OC/IC ratio gradually increased with time to about 5.0 on day 13. The average OC/IC ratio of ABP was 1.7 in DFM and, in contrast to Trf, declined to 0.7 in other serum-free media. Serum supplementation reversed and increased the ABP ratio to about 6.0 on day 13. These data indicate that Sc grown on permeable supports form confluent monolayers that limit the diffusion of macromolecules, most likely due to the formation of tight junctions. The monolayer permeability as well as the total and polarized secretion of Trf and ABP are differentially regulated by hormones and serum factors.

Q: Abstract: We examined the effects of a paramagnetic contrast agent, gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) on magnetic resonance images of acute myocardial infarction with and without reperfusion. Twenty-two dogs underwent occlusion of the left anterior descending coronary artery (LAD). In 10 dogs (group I) the LAD remained occluded for 3 hr and in the other 12 (group II) for 2 hr followed by 1 hr of reperfusion. Gd-DTPA (0.34 mM/kg) was administered to five dogs in group I at 2 hr and 5 min after occlusion and to seven dogs in group II 5 min after reperfusion. At 3 hr after ligation, the hearts were excised and imaged with spin echo and inversion recovery pulse sequences on a 0.35 Tesla magnetic resonance imager. Reperfused hearts given Gd-DTPA demonstrated a significant increase in contrast between normal and reperfused myocardium as compared with nonreperfused hearts and reperfused hearts not given Gd-DTPA. This enhancement was particularly prominent in the inversion recovery images. Studies performed in vivo in two additional dogs demonstrated similar enhancement with reperfusion with Gd-DTPA in gated spin echo images. Contrast-enhanced magnetic resonance imaging allows the detection of reperfusion early in the course of acute infarction.
