The influence of deciduoma-induced differentiation on the lipid peroxidation in the rat uterus was investigated. The wet weight of uterus and its protein content increased during deciduoma progression. Content of the thiobarbituric acid reactive substances (TBARS) as well as lipid peroxidation induced by ascorbate and cumene hydroperoxide showed significant decreases during deciduoma growth. Restoration of normalcy was observed during regression. The activity of superoxide dismutase, an inhibitor of lipid peroxidation showed an opposite pattern namely increase during deciduoma development and decline during the regressive phase. We conclude that cell differentiation during deciduoma induction is accompanied by a temporary and reversible decrease in the peroxidative potential of the rat uterus.

Review
Deciduoid mesothelioma was first described in young females and in the peritoneum, which led to the suggestion that deciduoid mesothelioma was a distinct subtype with specific clinical and pathologic features. Later reports, however, have shown that this type of mesothelioma may also occur in elderly people and in the pleura. Cases reported in the literature so far are limited, and the disease is not well defined. The authors report the histologic, immunohistochemical, ultrastructural, and clinical findings of 5 cases of deciduoid mesothelioma, and review the literature reports. The results demonstrate that the presence of numerous cytoplasmic intermediate filaments, either dispersed or bundled, appear to be the likely ultrastructural basis for the deciduoid histologic appearance. Twenty-one cases of deciduoid mesothelioma were identified in the literature. Analyses of these 21 cases and the authors' 5 cases showed an age range of 13-78 years (median 53 years) and a slight female predominance (female to male ratio of 1.4:1). Fourteen of 26 cases (54%) occurred in the peritoneum. Seven of 20 patients (35%) had a documented history of asbestos exposure. Fifteen of 20 patients died, with a mean survival time of 7.33 months (range 1-21 months). Five of 20 patients were alive at a follow-up time of 8 months to 5 years. These findings suggest that the so-called deciduoid mesothelioma has some clinical and pathologic features that are dissimilar to mesothelioma in general. Whether it truly represents a pathogenetically distinct variant or merely an expansion of the morphologic spectrum awaits further studies.

The effects of fetuses or placentas (with fetuses) removal on progesterone receptors (PR) in deciduomal tissues were investigated in unilateral pregnant (ULP) hamsters. Deciduomal reactions in response to artificial stimuli were induced on the tube-ligated uterine horns of ULP hamsters. Fetuses or placentas (with fetuses) were removed on day 8 of ULP, and the cytosolic and nuclear PR (cPR, and nPR, respectively) levels in deciduomal tissues at mesometrial (MS) and antimesometrial (AMS) sites were separately studied on day 10 and 12 of ULP. In the sham control group, cPR at the MS decreased with time, but at a slower rate than that at the AMS. The MS deciduoma contained higher cPR than the AMS deciduoma on day 12. Removal of fetuses did not cause any significant change of the decline rate, and the PR levels were similar to that of the control. The nPR at the MS and AMS also declined with time in all three groups. Removal of placentas induced drastic losses of cPR and nPR at the MS and AMS on day 10 and 12. Supplement of progesterone (P; 2 mg/animal/day) to the placenta-removed group restored the cPR somewhat at the MS site, but not back to the level of the control. The effect of P to restore nPR levels could be observed at the MS and AMS on day 10, but only at the MS on day 12. These data suggest that placental factor(s) other than P may play an important role on the maintenance of PR in deciduoma. Other cellular mechanisms may exist at the MS and AMS sites for the heterogeneous responses.

The modifications of enzymatics activities which involved dehydrogenases (LDH, MDH and G6PDH) alkalines phosphatases (Ph. Alc., ATP/as at Ph 7,2 and Ph 9,4) and hydrolases (Ph Ac. and beta Glu) were studied during the experimental deciduomata evolution in the Rat from the 5th to the 9th day. One the 5th day the uterus were used as control. Dehydrogenases and alkalines phosphatases activites appeared in isolated cells of sub-epithelial and middle antimesometrial stroma on the 5th day. Then, on the 6th day, they distributed themselves in strings of 8 to 10 cells. On the 7th day, they were regulary arranged in the decidual area. The growing decidual tissue was always surrounded by an hydrolysis activity.
