Post-abortion perceptions: a comparison of self-identified distressed and nondistressed populations.

This study investigated the experiences of 25 women who described themselves as responding in an emotionally distressed manner to abortion and a comparison group of 25 women reporting more relieving/neutral responses. Current and initial stress response to the abortion, general mental health, and demographic characteristics were assessed quantitatively, and interviews explored subjective perceptions. The distress group had significantly higher scores on initial stress response and religiosity, were more often currently affiliated with conservative churches, and reported lower degree of social support and confidence in the abortion decision. Qualitatively, 48% of the distress group recalled experiencing feelings of loss immediately post-abortion, in contrast to none in the nondistress group. Both groups identified post-abortion "catalytic" events, such as subsequent childbirth, that affected responses to the abortion over time.

Potential CNS antitumor agents VI: aziridinylbenzoquinones III.

Thirty-one aziridinylbenzoquinones were compared against five murine tumor models in vivo. Two intracerebral (ependymoblastoma and L-1210 leukemia) and three intraperitoneal (P-388 and L-1210 leukemia and B16 melanoma) systems were utilized. Excellent activity was observed for many compounds. Multiple long-term survivors were produced in the ependymoblastoma, P-388, and intraperitoneal L-1210 systems. Diethyl 2,5-bis(1-aziridinyl)-3,6-dioxo-1,4-cyclohexadiene-1,4-dicarbamate demonstrated superior activity in all five test systems. This compound also was reproducibly active against two colon tumors, a mammary tumor, and the intracerebrally implanted P-388 leukemia model.

Psychotropic drugs as potential antitumor agents: a selective screening study.

Compounds with known psychotropic properties were tested for activity in murine ip L1210 leukemia and B 16 melanoma in a protocol designed to obtain leads for new antitumor agents which might also possess central nervous system (CNS) antitumor properties. Barbiturates and hallucinogenic compounds were the only compound types deliberately excluded. Representatives from most of the other known CNS agent classes were included among the 297 psychotropic drugs evaluated. Sixteen of these agents were reproducibly active against the L1210 tumor system with T/C values of 125%. Phenothiazines such as fluphenazine and butyrophenones such as triperidol were prominent among the confirmed active structural types. Dopamine, a beta-phenethylamine neurotrasmitter, was active. While reproducible B16 melanoma activity was not observed among the psychotropic drugs, most of the L1210 confirmed active agents were effective against the ip P388 tumor model and also were active in vitro against KB cells. Ic L1210 activity was not observed among the few compounds chosen for testing in that tumor system. The yield of ip L1210 confirmed actives from this group of psychotropic agents was 18 times that which would have been expected from the random screening of compounds.
