[EX Q]: Abstract: In a stratified random sample of 320 white adults, the prevalence of puncture skin test positivity (ST +) to Lolium perenne (rye grass)-pollen extract (LPE) was 16%. Fifteen percent of all subjects (or 84% of subjects classified LPE IgE antibody positive [Ab +]) was classified IgE Ab + to highly purified Lol p I (Rye I), and 4% of all subjects (or 26% of subjects classified LPE IgE Ab +) was classified IgE Ab + to highly purified Lol p II (Rye II). These data and similar results obtained in an allergy-enriched group of 361 subjects are consistent with previous studies that Lol I is a major allergen and Lol II is a minor allergen of LPE. Whether we studied LPE, Lol I, or Lol II, responder subjects were younger than nonresponder subjects and more male than female subjects were responders. We then investigated the quantitative interrelationships among ST, IgE, and IgG Ab responsiveness to LPE, Lol I, and Lol II in the allergy-enriched group. For each allergen, log-log correlations were strong and significant for ST versus IgE Ab and for IgE Ab versus IgG Ab. All subjects IgE Ab + to Lol I or Lol II were IgG Ab + to that allergen, supporting other evidence for a commonality in the genetic control influencing the production of IgE and IgG Abs to a given allergen. Log-log correlations among ST end points, IgE Ab levels, or IgG Ab levels were strong for LPE versus either Lol I or Lol II but weak between Lol I and Lol II, consistent with the reported lack of cross-reactivity between Lol I and Lol II. Despite these findings, almost all Lol II + subjects were Lol I + by ST (98%), IgE Ab (91%), and IgG Ab (83%), suggesting that the Ia-restricted immune recognition of both these molecules is at least in part under a common genetic control.

[EX Q]: Abstract: The development of mouse and human embryos was assessed in human amniotic fluid to determine its suitability as a culture medium for human in vitro fertilization (IVF). Two-cell mouse embryos developed to blastocysts after 72 hours at rates similar to that in Whittingham's T6 + 10% fetal calf serum. Significantly more mouse embryos hatched in amniotic fluid. No difference was found between individual patient's amniotic fluids obtained at 16 to 21 weeks' gestation. A preliminary trial comparing amniotic fluid with T6 + maternal serum in human IVF showed no significant difference in fertilization rate and embryo development during 42 to 48 hours in vitro. Expanded blastocysts were obtained in amniotic fluid after 5 days in vitro. Four pregnancies were obtained in 9 patients' transferred embryos grown in amniotic fluid and with 2 or 12 patients' transferred embryos grown in T6 + maternal serum.

[EX Q]: Abstract: Administration of 650 pmol 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] to vitamin D-deficient chicks increased adenylate cyclase activity in the basolateral membrane of duodenal epithelial cells within 24 h. This increase in enzymatic activity was accompanied by an increase in calmodulin content of the basolateral membrane. Although neither exogenously added calmodulin (up to 10 micrograms/ml) nor calcium (from 10(-7)-10(-5) M) stimulated enzyme activity, calmodulin antagonists trifluoperazine, W7, and W13 inhibited it. When calmodulin content, adenylate cyclase activity, and alkaline phosphatase activity were measured in cells sequentially eluted from the tip to the base of the villus, cells from the midregion and base had the highest calmodulin content and adenylate cyclase activity, whereas alkaline phosphatase activity (a brush border membrane enzyme) was highest in cells eluted from the tip. Adenylate cyclase activity was increased by 1,25-(OH)2D3, particularly in cells from the midvillus. Our results indicate that the response of adenylate cyclase activity to 1,25-(OH)2D3 varies along the villus and suggest that calmodulin may be involved.
