Malaria Vaccine Development Unit, National Institute of Allergy and Infectious Diseases, Rockville, MD; Department of Entomology, Armed Forces Research Institute of the Medical Sciences, Bangkok, Thailand. A Phase I trial has been conducted to measure the safety and immunogenicity in humans of a recombinant protein vaccine based on the Plasmodium vivax ookinete surface protein Pvs25. The trial has been described in a companion paper. Volunteers were given two vaccinations of either 5, 20 or 80 protein adsorbed onto Alhydrogel, at 4-week intervals. Antibody levels were measured by ELISA in prevaccination sera, in sera collected 2 and 4 weeks after the first vaccination, and in sera collected 2 weeks following the second vaccination Day 42 sera ; . The antibody response varied from undetectable, to a titer of over 1000 reciprocal dilution at an OD correlation between antibody levels and vaccine dose was found. The ability of the induced antibodies to block transmission of P. vivax to mosquitoes was determined by mixing pre-bleed and day 42 sera with blood from naturally infected P. vivax patients, feeding this mixture to mosquitoes, and then counting the subsequent number of oocysts in these mosquitoes. From these data, further development of the vaccine is warranted, using other adjuvants and or formulations, to achieve sufficient immune responses in most vaccinees.

Related molecules, the mRNAs were partly inhibited by CsA, but were still induced compared with the level in resting T cells Fig. 2B ; . Taken together, these findings indicate that CsA, even at doses greater than those needed to inhibit activation, only partially protects against apoptosis. Also, the protection by CsA appears to be less effective as TCR occupancy is increased. Thus, these results are consistent with the finding that CsA cannot fully block the induction of death molecule mRNAs, whereas IL-2 mRNA is completely inhibited. We conclude that T cell activation events such as IL-2 expression differ from TCR-induced apoptosis, in that there appears to be a calcineurin-independent signaling pathway for the latter and treprostinil.
Platelet Aggregation Preliminary experiments * were performed on 40 mice given either tranylcypromine TCP ; , 50 mg kg, or vehicle, 1 hour before examination. Aggregation in arterioles was significantly facilitated P 0.05 ; . These experiments were followed by two others reported in Table 1. In each study, two doses of TCP were compared. The table shows that doses of 50 and 10 mg kg effectively enhanced aggregation. The doses we selected were based on our knowledge that a concentration of TCP of 500 ig ml is required in vitro for 100% inhibition of PGI2 synthesis.2 Simple calculations showed that the maximal dose we used 50 mg kg ; would be expected to produce blood levels of TCP somewhat lower than 500 ig ml. However, higher doses were toxic, and moreover, it was not thought necessary to inhibit 100% of enzyme activity in order to produce a biological effect. Iproniazid Effect on Platelet Aggregation Iproniazid, an MAO inhibitor without effect on PGI2 synthesis, 2 failed to facilitate aggregation as shown in Table 2. The doses of iproniazid selected in these studies were two and four times greater than the ED50 reported for rats and mice, 15 and thus effective inhibition of MAO was assured. As Table 2 indicates, iproniazid not only failed to facilitate platelet aggregation, but actually inhibited aggregation, as did aspirin and indomethacin in a previous study.7 Thus, both time to first aggregate and time to stop flow were significantly prolonged. Imidazole Effect on Platelet Aggregation This drug failed to have a consistant effect on platelet aggregation, as shown in Table 3. Discussion The data presented here offer In vivo evidence supporting the hypothesis that PGI2 synthesis is a significant factor inhibiting platelet aggregation in vivo.1"3 When we began these studies, no other in vivo evidence existed. A recent abstract by Higgs et al.5 reports that local irrigation with PGI2 inhibits platelet aggregation induced in hamster cheek pouch by regionally applied ADP. Because our study used a different species, a different vascular bed, and a different means of initiating aggregation, we believe the compatability of our data with that of Higgs et al. is especially important. We do not suggest that our data.

Abstract--The aim of the present study was to analyze the possible involvement of vasoconstrictors prostanoids on the reduced endothelium-dependent relaxations produced by chronic administration of aldosterone in Wistar Kyoto rats WKY ; and spontaneously hypertensive rats SHR ; . For this purpose, acetylcholine ACh ; relaxations in aortic segments from both strains were analyzed in absence and presence of the cyclooxygenase-1 COX-1 ; and COX-2 inhibitor indomethacin, the specific COX-2 inhibitor NS-398, the TP receptor antagonist SQ 29 548 ; , the thromboxane A2 TXA2 ; synthase inhibitor furegrelate, and the prostacyclin PGI2 ; synthesis inhibitor tranylcypromine TCP ; . In addition, COX-2 protein expression was studied by Western blot analysis. Release of prostaglandin E2 PGE2 ; and the metabolites of PGF2 , TXA2, and PGI2, 13, 14-dihydro-15-keto PGF2a, TXB2, and 6-keto-PGF1 , respectively, were measured. Treatment with aldosterone did not modify blood pressure levels in any strain. However, aldosterone markedly reduced P 0.05 ; ACh-induced relaxations in segments from both strains in a similar extent. Indomethacin, NS-398, SQ 29 548, and TCP enhanced P 0.05 ; ACh relaxations in both strains treated with aldosterone. Aortic COX-2 protein expression was higher in both strains of rats treated with aldosterone. In normotensive animals, aldosterone increases the ACh-stimulated aortic production of 13, 14-dihydro-15-keto PGF2a, PGE2, and 6-keto-PGF1 P 0.05 ; . In SHR, ACh only increased the 6-keto-PGF1 production P 0.05 ; . It could be concluded that chronic treatment with aldosterone was able to produce endothelial dysfunction through COX-2 activation in normotensive and hypertensive conditions. PGI2 seems to be the main factor accounting for endothelial dysfunction in hypertensive rats, whereas other prostanoids besides PGI2 appear to be involved in endothelial dysfunction under normotensive conditions.
