Abstract
ECa 233 is a standardized extract of Centella asiatica (CA), an herb widely used in traditional Chinese and Ayurvedic medicine. Previous studies reported that ECa 233 enhanced memory retention and synaptic plasticity in the hippocampus of healthy rats. Because of this, we became curious whether ECa 233 has a therapeutic effect on the fear memory deficit in the triple transgenic Alzheimer's disease (3xTg-AD) model mice. Fear memory is a crucial emotional memory for survival that is found to be impaired in patients with early-onset Alzheimer's disease (AD). In this study, we orally administered ECa 233 (doses: 10, 30, and 100[Formula: see text]mg/kg) to 3xTg-AD mice, who were five months old, for 30 consecutive days. We found that ECa 233 prevented a cued fear memory deficit and enhanced hippocampal long-term potentiation (LTP) in 3xTg-AD mice. Subsequent proteomic and western blot analyses revealed increased expression levels of the molecules related to LTP induction and maintenance, including brain-derived neurotrophic factor (BDNF), tyrosine receptor kinase B (TrkB) and its network proteins, and extracellular signal-regulated kinase 1 and 2 (ERK1 and 2) in the hippocampi and amygdala of 3xTg-AD mice after ECa 233 pre-treatment. Our results indicate that ECa 233 is a promising potential herbal standardized extract that could be used in preventing the fear memory deficit and synaptic dysfunction before the early onset of AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE ECa 233 is a standardized extract of Centella asiatica (L.) Urban, a herb traditionally used to treat a number of diseases including neurological disorders. Accordingly, ECa 233 showed benefits on animal models of cognitive deficits, chronic stress and Parkinson's disease. Analgesic activity of ECa 233 was shown in Tail's flick test in rodent and relieving aphthous ulcer pain in man. Moreover, acute and sub-chronic toxicity testing in rodents and pharmacokinetic study in healthy volunteers, clinical trial phase I demonstrated good safety profiles of ECa 233. AIM OF THE STUDY This study aims to evaluate the anti-nociceptive effects of ECa 233 and its synergistic effect with gabapentin on chronic neuropathic orofacial pain after 3 weeks infraorbital nerve chronic constriction injury in mice. The peripheral and central nociceptive activities are also examined. MATERIALS AND METHODS Chronic neuropathic orofacial pain was induced by 3 weeks infraorbital nerve chronic constriction injury. Mice were treated with ECa 233 (30, 100 and 300 mg/kg) and gabapentin (10 mg/kg) by oral gavage starting on day 21 and going on for 14 consecutive days. Mechanical hyperalgesia and allodynia were measured on day 7, 14, 21, 28 and 35 after infraorbital nerve chronic constriction injury. At the end of the experiment, mice were observed for the sedative effect using the locomotor activity, the calcitonin gen-related peptide in trigeminal ganglion and c-fos expression in trigeminal nucleus caudalis were investigated after euthanasia. RESULTS Infraorbital nerve chronic constriction injury gradually induced marked ipsilateral mechanical hyperalgesia and allodynia. The maximum hyperalgesia and allodynia response presented on day 21 and the response was remained constant until day 35. Treatment with either 300 mg/kg ECa 233 or 10 mg/kg gabapentin were able to attenuate mechanical hyperalgesia and allodynia. The downregulation of calcitonin gen-related peptide on ipsilateral trigeminal ganglion were observed in ECa 233 at 100 and 300 mg/kg and 10 mg/kg gabapentin-treated groups. The c-fos expression on ipsilateral trigeminal nucleus caudalis was also decreased in 300 mg/kg ECa 233 and 10 mg/kg gabapentin-treated groups. CONCLUSION ECa 233 reduced hyperalgesia and allodynia by modulating the peripheral calcitonin gen-related peptide expression consequently alleviate the nociceptive activity in trigeminal nucleus caudalis. Further clinical trial to proof ECa 233's efficacy in neuropathic pain in man as well as possible attributable mechanism of action should be further investigated.

Abstract
Background: Centella asiatica, a medicinal plant, has been used traditionally to promote wound healing. Its efficacy on promoting postlaser resurfacing wound healing is lacking. Methods: Thirty individuals with facial acne scars underwent a treatment with 2940 nm Er:YAG laser. Half side of the face was randomized to receive 0.05% w/w ECa 233 gel, a standardized extract of C. asiatica, and the other half a placebo gel. The gels were applied four times daily for 7 days then twice daily for 3 months. Erythema, melanin, and texture index (TI) from Antera3D,® and skin biophysics were obtained at baseline, days 2, 4, and 7, then every 2 weeks for the first month, and every month for 3 months. Three blinded dermatologists assessed the photographs and provided a grading scale of wound appearances. Results: The ECa 233 treated side exhibited significantly less erythema index over total follow-up by 0.03 U (coefficient = -0.03 [95% CI -0.06 to -0.0006]; p = 0.046). In keeping with the physicians' assessment that showed significantly higher improvements in skin erythema at days 2, 4, and 7 (p = 0.009, 0.0061, 0.012), crusting at days 2 (p = 0.02), and general wound appearance at days 2, 4, and 7 (p = 0.008, 0.001, 0.044), TI showed a trend toward better outcome in the ECa 233 group. Skin biophysics did not differ between the two groups. Conclusion: ECa 233 might be an option for postlaser treatment to improve wound appearance.

Abstract
1. ECa 233, the standardised extract of Centella asiatica, contains not less than 80% triterpenoid glycosides, in a madecassoside:asiaticoside ratio of 1.5 (±0.5):1. 2. The pharmacokinetic comparison of madecassoside and asiaticoside was performed in rats following intravenous and oral administration of ECa 233, or an equivalent dose of the individual compounds. Blood, tissues, urine and faeces were collected after dosing to determine drug and metabolite levels using liquid chromatography-tandem mass spectrometry. 3. Our study demonstrated that plasma levels of madecassoside, and to a lesser extent asiaticoside, were higher after administration of ECa 233 than the corresponding values for the pure compounds. There was a bidirectional interconversion between asiaticoside and madecassoside consistent with the increased exposure of madecassoside and asiaticoside in ECa 233. 4. Both madecassoside and asiaticoside appeared to be widely distributed in several organs and metabolized extensively; following intravenous administration of either compound, approximately 80-90% of the dose was recovered as madecassic acid and asiatic acid in the faeces.
