Cinnamon is a well-known natural spice and flavoring substance used worldwide. The objective of the present work is to explore the possible antitumor and immunomodulatory potencies of cinnamon essential oil (Cinn) on Ehrlich ascites carcinoma (EAC). A total of fifty female Swiss albino mice were sub-grouped into five groups (n = 10), namely, normal (a non-tumorized and non-treated) group; EAC-tumorized and non-treated group; Cinn (non-tumorized mice received Cinn, 50 mg/kg per body weight daily) group; a group of EAC-tumorized mice treated with Cinn and the final positive control group of EAC-tumorized mice received cisplatin. Eight compounds were identified from Cinn using UPLC-MS-Qtof and NMR analysis. Compared to EAC untreated group, Cinn successfully (P < 0.05) inhibited tumor growth by reducing tumor cell count (45%), viability (53%) and, proliferation accompanied by the inhibition of tumor growth rate. Moreover, a significant (P < 0.05) arrest in the cell cycle at G0/G1 phase was noticed following Cinn treatments (~ 24.5%) compared to EAC group. Moreover, Cinn markedly evoked an antitumor immune response by elevating the percentage of splenic T helper (CD3+CD4+) and T cytotoxic (CD3+CD8+) cells. It is noteworthy that Cinn treatments significantly restored different hematological alterations as well as liver and kidney functions in EAC-tumorized mice. In conclusion, results suggest that Cinn has a good antitumor and immunostimulatory potencies against Ehrlich ascites carcinoma in vivo. The mechanism underlying its antitumor activity may be attributed to its immunostimulatory effects which increase its potential as a promising anticancer candidate.

To investigate whether the use of a weighted trans-cervical Objective: fluid-filled Foley's catheter would improve the effectiveness of 400µg vaginal misoprostol regimen in terminating mid-trimester pregnancies.This study was conducted at the department of Obstetrics and Methods: Gynecology, Menofyia University Hospital in Egypt. Fifty eligible primigravidae were allocated into 2 groups. Termination was carried out in group I using vaginal misoprostol while in group II, a weighted fluid-filled intra-uterine Foley's catheter was inserted and a similar misoprostol regimen was followed as in group I.The combined group showed shorter induction to termination Results: interval (15.6 ± 4.9 versus 21.9 ± 5.4 hours; P<0.05). There was no significant difference in the occurrence of side effects between the groups.A combination of a weighted Foley's catheter and 400µg of Conclusion: vaginal misoprostol every 4 hours is more effective than misoprostol alone in terminating mid-trimester gestations.

The current study investigates anti-neoplastic and immunomodulatory activities of co-treatment based on bovine lactoferrin (bLF) and/or muramyl dipeptide (MDP) with or without cisplatin (Cis) in tumor-bearing mice. In the present study, bLF (100 mg/kg; orally) and MDP (0.5 mg/kg; subcutaneously) was administered alone or together. MDP or bLF was co-treated with Cis (1 mg/kg; intraperitoneally) in mice-bearing Ehrlich solid carcinoma. Tumor size, tumor mass proliferation, apoptosis using immunohistochemistry, the alteration in spleen cell proliferation, phenotype using flow cytometry and white blood cells total and differential counts were detected. Treatment with Cis or (bLF and MDP) significantly reduced tumor size, upregulated the pro-apoptotic p53 expression and downregulated the anti-apoptotic Bcl-2 and proliferative marker PCNA expression compared to non-treated tumor-bearing animals. Moreover, co-treatment of MDP and Cis significantly potentiated the reduction of the tumor size, downregulated the Bcl-2 and PCNA expression and upregulated the p53 expression compared to Cis-treated animals. While bLF and Cis co-treatment positively controlled PCNA and p53 expression compared to tumor-bearing animals, it significantly potentiated the reduction of the tumor size and downregulated the Bcl-2 expression compared to Cis-treated animals. Co-treatment of (bLF and MDP), (bLF and Cis) or (MDP and Cis) increased the spleen cell proliferation and altered the immunological profile of the CD3+CD4+, CD3+CD8+, CD3+CD4+CD69+, CD3+CD8+CD69+ and CD11b+Ly6G+ cells to achieve better immune response against tumor. In conclusion, co-treatments based on bLF and/or MDP are promising therapies against cancer, through their potency to control proliferation, enhance apoptosis and improve the immune status against tumor cells.
