[Q]: Abstract: Grevillea 'Robyn Gordon' is an Australian hybrid plant which may cause allergic contact dermatitis. Over the past 8 years, it has been planted extensively in Australia and is now being exported to the United States and other Western countries. Recently, an explosion in incidence of contact dermatitis due to this plant has been seen. 24 patients who were suspected of being sensitive to it were patch tested to fresh plant and extracts with confirmation of sensitivity. A cross sensitivity to Toxicodendron was demonstrated clinically and on patch testing. The allergen in Toxicodendron, 3 pentadecylcatechol, is closely linked in chemical structure to 5-pentadecylresorcinol, present in Grevillea banksii and tridecylresorcinol in Grevillea robusta. Patch testing in patients sensitive to Grevillea 'Robyn Gordon' with tridecylresorcinol produced positive reactions, thus implicating the sensitizing role of long chain alkyl resorcinols in Grevillea 'Robyn Gordon' allergy. There is a likelihood that this sensitizing potential extends to other plants of the Grevillea genus, e.g., Grevillea robusta. With the spread of Grevillea 'Robyn Gordon' to other markets, this problem will become increasingly common.

[Q]: Abstract: In 10-day-old suckling and adult mice, reovirus type 1 adheres selectively to and penetrates membranous epithelial (M) cells. To determine when M cells first appear, when they first transport reovirus, and if reovirus adheres to and is endocytosed by other epithelial cells in the first postnatal week, we examined neonatal mouse intestine by transmission electron microscopy after reovirus type 1 exposure. At 2 days M cells accounted for 0.9% of dome epithelial cells. By 9 days M cells had increased to 7.4%. Reovirus type 1 adherence to the surface of villus and dome epithelial cells showed marked variation in 2-6-day-old animals, but by 7 days only a few absorptive cell profiles had adherent reovirus. Adherence to greater than 50% of M-cell profiles occurred in all but 2 animals, but adherence to the majority of Peyer's patch absorptive cell profiles was present only in some 4- and 5-day-old animals. Adherence to a majority of undifferentiated cell profiles occurred in some animals at all ages. Membranous epithelial cells endocytosed reovirus at all ages but only at 2 days did rare villus and dome absorptive cells endocytose reovirus into the apical cytoplasm. Thus, adherence of reovirus to the apical surface of mucosal epithelial cells is nonselective in newborn mice but becomes more selective within the first postnatal week with adherence by day 7 to most M-cell profiles, to a substantial but variable number of undifferentiated cell profiles, but to few absorptive cell profiles.

[Q]: Abstract: To study the relationship between lung weight and lymph flow, we used an in situ, isolated sheep lung preparation that allowed these two variables to be measured simultaneously. All lungs were perfused for 4.5 h at a constant rate of 100 ml X min-1 X kg-1. In control lungs, the left atrial pressure (Pla) was kept at atmospheric pressure. In experimental lungs, Pla was kept atmospheric except for a 50-min elevation to 18 mmHg midway through the perfusion. During this period of left atrial hypertension, pulmonary arterial pressure rose from 18 to 31 mmHg, lymph flow rose from 3 to 12 ml/h, and the lymph-to-plasma oncotic pressure ratio (pi L/pi P) fell from 0.7 to 0.48. After left atrial pressure was returned to control, pulmonary arterial pressure, lymph flow, and pi L/pi P all returned to control levels. The rate of weight gain after the return of left atrial pressure to control was also the same as that in the control group. However, during the period of left atrial hypertension 135 ml of fluid were filtered into the lung, and this large increase in lung weight remained after the pressure was lowered. The presence of this substantial excess lung water despite control values for vascular pressures, lymph flow, rate of weight gain, and pi L/pi P suggests that the absolute amount of lung water has little influence on the dynamic aspects of lung fluid balance. These results are consistent with a two-compartment model of the interstitial space, where only one of the compartments is readily drained by the lymphatics.
