Background: Pain is a major complaint in cancer patients and a global problem that requires medical attention, including pain in cervical cancer. Although pharmacotherapy has been used for the treatment of cancer pain, there are still around 40% cannot be treated only with pharmacotherapy. Objectives: To determine the effects of electroacupuncture (EA) on pain in stage III cervical cancer patients. Methods: Twenty-eight stage III cervical cancer patients were divided into two groups (14 treatments and 14 controls) with randomized control trial design. The treatment group received EA with a frequency of 2/20-25 Hz at points of ST36, SP6, LI4 and LR3 for 30 minutes, while the control group did not receive EA. Both groups were given paracetamol and codeine at the same dose. Assessment was carried out by measuring pain scale (VAS), plasma β-endorphin levels, and quality of life/QoL (EORTC QLQ-C30) before and after therapy. Results: The average reduction in VAS in the treatment group (2.71 ± 1.14) compared to the control group (0.71 ± 1.33; p < 0.001), average increase in plasma β-endorphin levels in the treatment group (88.57 ± 52.46 pg/ml) compared to the control group (12.86 ± 56.76 pg/ml; p = 0.001), and in QoL, there were significant differences in symptom improvement between the treatment and control groups in the domain of fatigue, pain, insomnia and overall QoL (p < 0.05). Conclusion: Medical therapy combined with EA decreased pain scale, increased plasma β-endorphin levels, and improved the QoL for stage III cervical cancer patients.
Objective:
This study aimed to determine the cytoprotective potentials of citronella (
Cymbopogon nardus
(L.) Rendl.) essential oil (CO) and lemongrass (
Cymbopogon citratus
(DC.) Stapf) essential oil (LO).
Methods:
The essential oils from citronella and lemongrass were obtained by steam-water distillation, then analyzed using Gas Chromatography-Mass Spectrophotometry (GC-MS) to determine the chemical constituents. The antioxidant activity of CO and LO was compared using a total antioxidant capacity kit. The viability of normal kidney epithelial cells Vero and fibroblast NIH-3T3 as the cell models were tested using a trypan blue exclusion assay. The effect of cellular senescence inhibition on both cell models was measured using senescence-associated β-galactosidase (SA-β-gal) staining. The mechanism of action of CO and LO in the protection of cellular damage against doxorubicin was also confirmed through 2’,7’–dichlorofluorescin diacetate (DCFDA) staining to discover the ability to decrease reactive oxygen species (ROS) levels and a gelatin zymography assay to observe the activity of matrix metalloproteinases (MMPs).
Results:
The major marker components of CO and LO were citronellal and citral, respectively. Both oils showed low cytotoxic activity against Vero and NIH-3T3 cells, with IC
50
values of over 40 µg/mL. LO exhibited higher antioxidant capacity than CO, but there was no effect on the intracellular ROS level of both oils on Vero and NIH-3T3 cells. However, CO and LO decreased cellular senescence induced by doxorubicin exposure on both cells, as well as suppressed MMP-2 expression.
Conclusion:
Both CO and LO decrease the cellular senescence and MMP-2 expression with less cytotoxic effects on normal cells independently from their antioxidant capacities. The results were expected to support the use of CO and LO as tissue protective and anti-aging agents in maintaining the body’s cellular health against chemotherapeutics or cellular damaging agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
