14C-piperacillin (Pipracil) at a dose level of 1000 mg/kg was administered intravenously or intraperitoneally to pregnant and non-pregnant female rats. Rats were sacrificed at predetermined time intervals, and 14C-piperacillin concentrations determined in serum, amniotic fluid, placenta, and fetus. The piperacillin serum levels in both pregnant and nonpregnant rats following intravenous administration were comparable; however, following intraperitoneal administration, the serum drug levels in the pregnant rats as compared to the nonpregnant rats were lower. The fetal drug levels, however, were higher following intraperitoneal administration than following intravenous administration. The total area under the fetal drug concentration-time curve following intraperitoneal administration was about two times the corresponding area under the curve following intravenous administration. The data indicate that the fetal exposure to piperacillin was greater following intraperitoneal administration.

Secondary affective disorder in women with somatization disorder.

Of 60 women with somatization disorder (SD), 54 (90%) met DSM-III criteria for a major affective episode. This group with secondary affective disorder (SAD) was compared with 29 women who had primary affective disorder (PAD). SAD patients reported significantly more symptoms, more psychiatric admissions, more and longer episodes of depression; more had attempted suicide, and more had made multiple attempts. SAD patients had often been hospitalized and were likely to have been treated with lithium and a variety of antidepressants. Studying relatively homogeneous primary psychiatric diagnoses facilitates the identification of distinctions between SAD and PAD patients.

The metabolic fate of triamcinolone acetonide in laboratory animals.

The metabolic fate of 9-fluoro-11beta,16alpha,17,21-tetrahydroxy-1,4-pregnadiene-3,20-dione cyclic 16,17-acetal with 2(-14)C-acetone, triamcinolone acetonide (TA) was studied in rabbits, dogs, monkeys and rats and found to be qualitatively similar in all species. In the dog, rat and monkey the major excretory route was the feces irrespective of the mode of administration. In the rabbit the excreted radioactivity was equally distributed between urine and feces. The metabolites were isolated by preparative thin layer chromatography, located by autoradiography, eluted and analyzed by MS, IR, UV and NMR. The major metabolites of triamcinolone acetonide (TA) were identified as the C-21 carboxylic acids of TA and of the 6beta hydroxy-TA, (6BETA-OH-TA) and the previously identified (1,2) 6beta-OH-TA. In addition MS and UV data indicate the presence of 9-fluoro-11beta,16alpha, 17-trihydroxy-3,20-dioxo-1,4,6-pregnatrien-21-oic acid cyclic 16,17 acetal with 2(-14)C-acetone.
