Article Abstract
Background: Citrus aurantium is a small citrus tree, with scented white flowers. The C. aurantium is used in Asian herbal medicine primarily to treat digestive problems.
Objective: The goal of this study is to investigate the effect of C. aurantium flower's aqueous extract on uterine contraction in presence of some known uterus stimulants.
Materials And Methods: In experimental study 30 virgin Wistar rats 200-300gr were obtained. After laparatomy, a piece of Uterus was dissected out and mounted in an organ bath (10ml) containing De Jalon (29°C) and contracted by KCl (60mM), oxytocin (10mU/ml) and barium chloride (4mM) then the effect of C. aurantium flower's aqueous extract (1-8 mg/ml) on the uterine contractions was investigated.μμthe role of β-adrenoceptors, opioid receptors were evaluated.
Results: Cumulative concentrations of the extract (1-8 mg/ml) decreased KCl, oxytocin and barium chloride induced uterine contractions, dose-dependently (p<0.001). C. aurantium flower's aqueous extract was unaffected on incubation the tissue with propranolol and naloxone.
Conclusion: It seems that the extract induced antispasmodic effect mainly via calcium influx blockade. However, neither β-adrenoceptors nor opioid receptors were involved. Since the extract has antispasmodic effect on uterus contraction therefore we can suggest that more study will be necessary to relief dysmenorrheal.

Schistosomiasis, caused by Schistosoma worms, is a major neglected tropical disease in Africa, this disease is ranked as second after malaria. Nanotechnology is important for treating schistosomiasis while minimizing chemotherapy side effects. The current investigate aimed to assess the effectiveness of biosynthesized zinc oxide nanoparticles (ZnO NPs), which were used for the first time in an attempt to find alternative treatment for schistosomiasis and synthesized by Origanum majorana, and to compare them with praziquantel (PZQ), the only chemical treatment approved by the World Health Organization.

In this study, copper nanoparticles with an average particle size of 2-4 nm were synthesized using the green extract of Thunb. The catalytic activity and dye degradation efficiency of Cu NPs were evaluated using ultraviolet spectroscopy. To confirm that Cu NPs can continuously remove organic dyes, this study used Cu/Lj-C composite material adsorbed on cotton balls as a simulated bed to study the cyclic catalytic activity of Cu NPs for the reduction of methylene blue by sodium borohydride (NaBH).

Zirconium dioxide nanoparticles (ZrO NPs) have gained significant attention due to their excellent bioavailability, low toxicity, and diverse applications in the medical and industrial fields. In this study, ZrO NPs were synthesized using zirconyl oxychloride and the aqueous leaf extract of as a stabilizing agent. Analytical techniques, including various spectroscopy methods and electron microscopy, confirmed the formation of aggregated spherical ZrO NPs, ranging from 15 to 30 nm in size, with mixed-phase structure composed of tetragonal and monoclinic structures.
