The objective of this study was to evaluate the effectiveness of topical lavender-thymol in promoting episiotomy healing. This placebo-controlled, single-blinded, randomised clinical trial involved 60 primiparous women. REEDA score was used to evaluate the outcome of the trial. On the 7th post-partum day, women in Placebo-treated group had worse Redness, Edema, Ecchymosis, Discharge and Approximation (REEDA) score of 3.93 ± 3.65 compared with those in Lavender-thymol-treated group (2.03 ± 1.7) with significant difference (P = 0.013). Visual analogue Scale (VAS) score for pain at episiotomy in Lavender-thymol-treated group was 3.5 ± 1.9, whereas in Placebo-treated group it was 2.1 ± 2.2 (p = 0.011) for dyschezia, 3.8 ± 1.7 and 2.8 ± 1.6 in Placebo- and Lavender-thymol-treated women, respectively (p = 0.023). At 7th post-partum week, dyspareunia was more severe in Placebo-treated group compared with that in Lavender-thymol-treated group (5.3 ± 2.7 vs 2.7 ± 1.5 and p < 0.001). Topical aromatherapy using lavender-thymol was highly effective, suitable and safe for episiotomy wound care with little or no expected side effects compared with that using placebo.
The yield of steam distillation of frankincense essential oil (3%); and its physicochemical constants were determined. Capillary GC/MS technique was used for the analysis of the oil. Several oil components were identified based upon comparison of their mass spectral data with those of reference compounds published in literature or stored in a computer library. The oil was found to contain monoterpenes (13.1%), sesquiterpenes (1%), and diterpenes (42.5%). The major components of the oil were duva-3,9,13-trien-1,5α-diol-1-acetate (21.4%), octyl acetate (13.4%), o-methyl anisole (7.6%), naphthalene decahydro-1,1,4a-trimethyl- 6-methylene-5-(3-methyl-2-pentenyl) (5.7%), thunbergol (4.1%), phenanthrene-7- ethenyl-1,2,3,4,4a,5,6,7,8,9,10,10a-dodecahydro-1,1,4a,7-tetramethyl (4.1%), α-pinene (3.1%), sclarene (2.9%), 9-cis-retinal (2.8%), octyl formate (1.4%), verticiol (1.2%) decyl acetate (1.2%), n-octanol (1.1%). The chemical profile of the oil is considered as a chemotaxonomical marker that confirmed the botanical and geographical source of the resin. Biologically, the oil exhibited a strong immunostimulant activity (90% lymphocyte transformation) when assessed by a lymphocyte proliferation assay.
It is possible to conclude that both systemic and peripheral mechanisms seem to be implicated in the modulating effect of acupuncture on the neurogenic inflammation mechanism.
The immunomodulatory bioassay-guided fractionation of the oleogum resin of frankincense (Boswellia carterii Bird wood) resulted in the isolation and identification of 9 compounds; palmitic acid and eight triterpenoids belonging to lupane, ursane, oleanane, and tirucallane skeleta were isolated form the resin. These triterpenoids are lupeol, -boswellic acid, 11-keto--boswellic acid, acetyl -boswellic acid, acetyl 11-keto--boswellic acid, acetyl-α-boswellic acid, 3-oxo-tirucallic acid, and 3-hydroxy-tirucallic acid. The structures of the isolated compounds were deduced based on spectroscopic evidences. The lymphocyte transformation assay of the isolated compounds proved that the total extract retained more activity than that of any of the purified compounds.
The current study aimed to discuss the potential of nanospanlastics as a surfactantbased vesicular system for improving the topical delivery of 3-acetyl-11-keto-β-boswellic acid (AKBA). AKBA is a potent anti-inflammatory drug, but it has poor oral bioavailability due to its poor aqueous solubility. Moreover, the topical delivery of AKBA is difficult due to its high lipophilicity. To overcome these drawbacks, AKBA was formulated as deformable elastic nanovesicles and nanospanlastics, for improving its topical delivery. Materials and Methods: AKBA-loaded spanlastic nanovesicles (SNVs) were formulated by ethanol injection technique according to 2 3 factorial design using Span 60 as a non-ionic surfactant and Tween 80 as edge activator (EA) to investigate the effect of different independent variables on entrapment efficiency (EE%), % drug released after 8 hr (Q 8h) and particle size (PS) using Design-Expert software. In vitro characterization, stability test and ex vivo permeation study of the optimized formula were performed. Results: The choice of the optimized formula was based on the desirability criteria. F7 was selected as the optimized formula because it has the highest desirability value of 0.648. F7 exhibited EE% of 90.04±0.58%, Q 8h of 96.87±2.67%, PS of 255.8±2.67 nm, and zeta potential of −49.56 mV. F7 appeared as spherical well-defined vesicles in both scanning electron microscope (SEM) and transmission electron microscope (TEM). The Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) studies investigated the absence of interaction between AKBA and different excipients and good encapsulation of AKBA within SNVs. F7 retained both physical and chemical stability after storage for 3 months at 4-8 °C. Ex vivo permeation test exhibited significant enhancement of permeability of F7 across rat skin than the free drug. Conclusion: Nanospanlastics could be a promising approach for improving the permeability and topical delivery of AKBA.
