[PMID: 34877308 PMCID: PMC8610874 DOI: 10.12998/wjcc.v9.i31.9691] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 08/02/2021] [Accepted: 09/16/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Adrenoleukodystrophy (ALD) is caused by a deficit in the ABCD1 gene, which leads to demyelination of neurons and dysfunction of the adrenal cortices and testicles. Of the three known phenotypes, 30%-50% of male ALD patients present with the adrenomyeloneuropathy phenotype, characterized by gait disturbance as the initial symptom.
CASE SUMMARY A 46-year-old man with a prior diagnosis of ALD was admitted to a Korean medicine hospital for the treatment of gait disturbance. His ability to walk was severely impaired at admission, significantly affecting the patient’s quality of life. He was treated with acupuncture, pharmacopuncture, electroacupuncture, and herbal medicine for 23 d. The 25-Foot Walk test (25FW), timed up and go (TUG), comfortable gait speed (CGS), numeric rating scale (NRS), Berg Balance Scale (BBS), Tinetti test, manual muscle test (MMT), and 3-level version of EuroQol-5 dimension (EQ-5D-3L) were used to evaluate the patient. The outcomes of the 25FW, TUG, and CGS improved during hospitalization. From the time of admission to discharge we observed: A decrease in NRS scores in the lower extremities and the lower back; an increase of 3 points in the BBS; a 1-point increase in the balancing part of the Tinetti Test; MMT and EQ-5D-3L performances remained unchanged.
CONCLUSION Traditional Chinese medicine treatments could be a therapeutic option to alleviate issues related to gait disturbance in ALD.

Wu G, Xu X, Ye F, Shu H. Effects of processed Aconiti tuber on the extinction and reinstatement of morphine-induced conditioned place preference in rats. JOURNAL OF ETHNOPHARMACOLOGY 2021; 267:113524. [PMID: 33129945 DOI: 10.1016/j.jep.2020.113524] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 09/10/2020] [Accepted: 10/26/2020] [Indexed: 06/11/2023]
Abstract
AIM OF THE STUDY To investigate the effect of processed Aconiti tuber (PAT) administered during or after the time of conditioned place preference (CPP) training on the extinction and reinstatement of morphine-priming CPP in rats. The dynorphin level in rats' nucleus accumbens (NAc) is detected as a target of the Dynorphin/Kappa Opioid Receptor (KOR) system for the possible mechanism. MATERIALS AND METHODS Eight groups of rats were subcutaneously (s.c.) injected with morphine (10mg/kg) (on days 2,4,6,8) or saline (1ml/kg) (on days 3,5,7,9) alternately for 8 days. Five groups, including groups (Mor + Water, Mor + PAT (1.0/3.0g/kg) (S) and Sal + PAT(1.0/3.0g/kg)), were orally given distilled water or PAT 1.0 or 3.0 g/kg daily on days 1-8 during CPP training while other three groups, including groups (Sal + Water and Mor + PAT (1.0/3.0g/kg)(P), were given distilled water or PAT daily from day 10 until CPP was extinct. Morphine 1mg/kg (s.c.) was used to reinstate the extinct CPP and the CPP scores were recorded. The dynorphin concentration in nucleus accumbens (NAc) was assayed by radioimmunoassay after the last CPP measurement. RESULTS 1) The CPP extinction shortened in Mor + PAT (1.0/3.0 g/kg) (S) groups but extended in Mor + PAT (1.0/3.0 g/kg)(P) groups. 2) Morphine-priming CPP did not change either in Mor + PAT (1.0/3.0 g/kg) (S) or Mor + PAT (1.0/3.0 g/kg)(P) groups. 3) The dynorphin concentration in NAc increased either in Mor + PAT (1.0/3.0 g/kg)(S) or Mor + PAT (1.0/3.0 g/kg)(P) groups. CONCLUSIONS 1) PAT shortened the extinction from morphine induced CPP when administrated before CPP acquisition, whereas it extended the extinction when administrated after CPP formation. 2) PAT administrated during or after CPP training did not affect morphine-priming reinstatement of morphine induced CPP. 3) Dynorphin/KOR system might be a target to regulate morphine-induced CPP extinction but not reinstatement.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 259:112963. [PMID: 32439405 DOI: 10.1016/j.jep.2020.112963] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 04/11/2020] [Accepted: 05/07/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Goshajinkigan (GJG), a traditional Japanese Kampo formula, has been shown to exhibit several pharmacological actions, including antinociceptive effects. Processed aconite root (PA), which is considered to be an active ingredient of GJG, has also been demonstrated to have an ameliorative effect on pain, such as diabetic peripheral neuropathic pain. We recently identified neoline as the active ingredient of both GJG and PA that is responsible for its effects against oxaliplatin-induced neuropathic pain in mice. AIM OF THE STUDY In the present study, we investigated whether GJG, PA, and neoline could inhibit Nav1.7 voltage-gated sodium channel (VGSC) current and whether neoline could ameliorate mechanical hyperalgesia in diabetic mice. MATERIALS AND METHODS To assess the electrophysiological properties of GJG extract formulation, powdered PA, and neoline on Nav1.7 VGSCs, whole-cell patch clamp recording was performed using human HEK293 cells expressing Nav1.7 VGSCs. In addition, the ameliorative effects of neoline on diabetic peripheral neuropathic pain were evaluated using the von Frey test in streptozotocin (STZ)-induced diabetic model mice. RESULTS GJG extract formulation significantly inhibited Nav1.7 VGSC peak current. Powdered PA also inhibited Nav1.7 VGSC peak current. Like GJG and PA, neoline could inhibit Nav1.7 VGSC current. When diabetic mice were treated with neoline by intraperitoneal acute administration, the mechanical threshold was increased in diabetic mice, but not in non-diabetic mice, in a behavioral study. CONCLUSION These results suggest that neoline might be a novel active ingredient of GJG and PA that is one of responsible ingredients for ameliorating mechanical hyperalgesia in diabetes via the inhibition of Nav1.7 VGSC current at least.

JOURNAL OF ETHNOPHARMACOLOGY 2017; 196:151-159.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bullatine A, a C20-diterpenoid alkaloid and one of the major effective ingredients in Aconiti brachypodi Radix (Xue-shang-yi-zhi-hao), can block pain hypersensitivity in a variety of rodent models through expression of spinal microglial dynorphin A. AIM OF THE STUDY To assess the interaction between bullatine A and morphine on antinociception in acute nociception and pain hypersensitivity states, with the exogenous synthetic dynorphin A as a comparison MATERIALS AND METHODS: Spinal nerve ligation-induced neuropathic rats and naïve mice were used for assessing the acute and chronic interactions of bullatine A/dynorphin A with morphine. RESULTS Single subcutaneous injection of bullatine A or dynorphin A(1-17) did not either alter formalin- and thermally (hot-plate and water immersion tests)-induced acute nociception or potentiate morphine antinociception in naïve mice. In contrast, bullatine A dose-dependently inhibited formalin-induced tonic pain with the efficacy of 54% inhibition and the half-effective dose of 0.9mg/kg. Concurrent bullatine A additively enhanced morphine antinociception. In neuropathic rats, the antinociceptive effects of multiple bidaily intrathecal injections of bullatine A and dynorphin A remained consistent over 13 days, whereas morphine produced progressive and complete tolerance to antinociception, which was completely inhibited by concurrent bullatine A and dynorphin A. A single intrathecal injection of bullatine A and dynorphin A immediately reversed established morphine tolerance in neuropathic rats, although the blockade was a less degree in the thermally induced mouse acute nociceptive tests. The inhibitory effects of bullatine A and dynorphin A on morphine tolerance were immediately and completely attenuated by intrathecal dynorphin A antibody and/or selective κ-opioid receptor antagonist GNTI. CONCLUSION These results suggest that bullatine A produces antinociception without induction of tolerance and inhibits morphine antinociceptive tolerance, and provide pharmacological basis for concurrent bullatine A and morphine treatment for chronic pain and morphine analgesic tolerance.

Abstract
Processed Aconiti tuber (PAT) is used to treat pain associated with various disorders. Although it has been demonstrated that the κ opioid receptor (KOR) signaling pathway is a mediator of the analgesic effect of PAT, active components affecting opioid signaling have not yet been identified. In this study, we explored candidate components of PAT by pharmacokinetic analysis and identified ignavine, which is a different structure from aconitine alkaloids. A receptor binding assay of opioid receptors showed that ignavine specifically binds the μ opioid receptor (MOR), not the KOR. Receptor internalization assay in MOR-expressing cell lines revealed that ignavine augmented the responses produced by D-Ala(2)-N-Me-Phe(4)-Gly-ol(5)-enkephalin (DAMGO), a representative MOR agonist, at a low concentration and inhibited it at a higher concentration. Ignavine also exerted positive modulatory activity for DAMGO, endomorphin-1 and morphine in cAMP assay. Additionally, ignavine alone showed an analgesic effect in vivo. In silico simulation analysis suggested that ignavine would induce a unique structural change distinguished from those induced by a representative MOR agonist and antagonist. These data collectively suggest the possibility that ignavine could be a novel allosteric modulator of the MOR. The present results may open the way for the development of a novel pain management strategy.

Processed aconite root and its active ingredient neoline may alleviate oxaliplatin-induced peripheral neuropathic pain. JOURNAL OF ETHNOPHARMACOLOGY 2016; 186:44-52. [PMID: 27038579 DOI: 10.1016/j.jep.2016.03.056] [Citation(s) in RCA: 42] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2015] [Revised: 03/06/2016] [Accepted: 03/27/2016] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Processed aconite root (PA, the root of Aconitum carmichaeli, Ranunculaceae) is a crude drug used in traditional Chinese or Japanese kampo medicine to generate heat in the body and to treat pain associated with coldness. Oxaliplatin (L-OHP) is a platinum-based anticancer drug that frequently causes acute and chronic peripheral neuropathies, including cold and mechanical hyperalgesia. AIM OF THE STUDY We investigated the effects of PA on L-OHP-induced peripheral neuropathies and identified the active ingredient within PA extract. MATERIALS AND METHODS L-OHP was intraperitoneally injected into mice, and PA boiled water extract was orally administered. Cold and mechanical hyperalgesia were evaluated using the acetone test and the von Frey filament method, respectively. Dorsal root ganglion (DRG) neurons were isolated from normal mice and cultured with L-OHP with or without PA extract. Cell viability and neurite elongation were evaluated. RESULTS PA extract significantly attenuated cold and mechanical hyperalgesia induced by L-OHP in mice. In cultured DRG neurons, L-OHP reduced cell viability and neurite elongation in a dose-dependent manner. Treatment with PA extract significantly alleviated the L-OHP-induced reduction of neurite elongation, while the cytotoxicity of L-OHP was not affected. Using activity-guided fractionation, we isolated neoline from PA extract as the active ingredient. Neoline significantly alleviated L-OHP-induced reduction of neurite elongation in cultured DRG neurons in a concentration-dependent manner. Moreover, subcutaneous injection of neoline attenuated cold and mechanical hyperalgesia in L-OHP-treated mice. PA extract and neoline did not show sedation and motor impairment. CONCLUSIONS The present study indicates that PA and its active ingredient neoline are promising agents to alleviate L-OHP-induced neuropathic pain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The processed lateral root of Aconitum carmichaelii Debeaux (Ranunculaceae), an extensively used traditional Chinese medicine, is known as Fuzi in China (Chinese: ), "bushi" in Japan, "Kyeong-Po Buja" in Korea, Chinese aconite, monkshood or Chinese wolfsbane. It has been used to treat shock resulting from acute myocardial infarction, low blood pressure, coronary heart disease, chronic heart failure, etc. AIM OF THE REVIEW The present paper aims to provide an up-to-date review at the advancements of the investigations on the ethnopharmacology, phytochemistry, pharmacological effect and toxicity of Fuzi. Besides, the possible tendency and perspective for future research of this plant are discussed, as well. MATERIALS AND METHODS All available information on Fuzi was collected via electronic search (using Elsevier, PubMed, ACS, CNKI, Google Scholar, Baidu Scholar, and Web of Science), books and classic works about Chinese herb. RESULTS 122 chemical constituents, among which C19-diterpenoid alkaloids and C20-diterpenoid alkaloids are the predominant groups, have been isolated and identified from Fuzi. Fuzi with its active compounds is possessed of wide-reaching biological activities, including effects on cardiovascular system, anti-inflammation and analgesic action, anti-tumor activity, effect on the immune system, hypoglycemic and hypolipidemic effects, anti-aging effect, effect of protecting kidney and effect on energy metabolism. CONCLUSIONS Nearly all of compounds were found from the roots of the plant, so further phytochemical studies should focus more on the other parts of the plant, such as the leaves, flowers or stems. Besides, a majority of the pharmacological studies were carried out using crude and poorly characterized extracts. Thus, more bioactive components particularly cardiotonic and analgesic compounds should be identified through bioactivity-guided isolation strategies. Moreover, investigations on how to develop Fuzi׳s new clinical usage on the basis of its pharmacological effects are in requirement.

Aqueous root extracts from Mimosa albida Humb. & Bonpl. ex Willd display antinociceptive activity in mice. JOURNAL OF ETHNOPHARMACOLOGY 2013; 149:522-526. [PMID: 23906780 DOI: 10.1016/j.jep.2013.07.010] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2012] [Revised: 06/18/2013] [Accepted: 07/06/2013] [Indexed: 06/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In this work, we study whether aqueous extracts from the roots of Mimosa albida Humb. & Bonpl. ex Willd, a plant known in the Highlands of Chiapas, Mexico as "Lotóm chíx" are endowed with both antinociceptive and anxiolytic effects. MATERIALS AND METHODS ICR mice were systemically treated with aqueous extracts from Mimosa albida and the reference compounds (diazepam, dipyrone and/or fentanyl) and their behavior was evaluated in several behavioral tests. RESULTS Administration of aqueous extracts from the roots of Mimosa albida resulted in a reduction of the nociception elicited in mice by both the hot plate (12.5, 25 and 50 mg/kg; i.p.) and the acetic acid-induced writhing (25 and 50 mg/kg; i.p.) tests. No effects were however observed both in the elevated plus-maze and hole board test (3.2, 12.5 and 25 mg/kg; i.p.). In contrast, both locomotion (open field test) and motor coordination (rotarod test) were affected at doses (50, 100 y 200 mg/kg; i.p.) higher than those having antinociceptive effects. CONCLUSION These data suggest that in mice the systemic administration of low doses of aqueous extracts from the roots of Mimosa albida results in antinociceptive effects in several models of pain through mechanisms that do not involve the opioid system pathway. These results support the ethnopharmacological use of Mimosa albida in popular medicine.

Abstract
OBJECTIVES It has been reported that postherpetic neuralgia (PHN) in patients over 60 years of age is aggravated under cold stimulation and is often difficult to treat. Keishikajutsubuto (TJ-18) and Bushi-matsu (TJ-3022) are traditional Japanese herbal medicines and have long been used to treat neuralgia and arthralgia, which are aggravated following cold stimulation. This study was designed to evaluate the effectiveness of combined TJ-18 and TJ-3022 therapy in cases of PHN aggravated by self-reported cold stimulation. DESIGN Fifteen (15) PHN patients aged 60 years and over were examined. Patients were aware of the persistent pain despite other treatments; pain was generally aggravated following exposure to cold stimulation. First, TJ-18 (7.5 g/day) was administered to patients, and then TJ-3022 (1.0 g/day) was also administered and progressively increased by 0.5-1.0 g increments every 2-4 weeks, until stable improvement was achieved, which was rated using the visual analogue scale (VAS). Analgesic effects were evaluated using the VAS during each patient visit. OUTCOME MEASURES Background variables, responses to treatment (time course of VAS rating, VAS improvement rate), the amount of additional TJ-3022 administered, and adverse reactions were analyzed. RESULTS Twelve (12) of the 15 patients completed the entire trial. Patient ages were 61-85 years, the male-to-female ratio was 4:8, and length of time after onset of herpes zoster was 2-92 months. In 3 patients, oral TJ-18 treatment was not possible due to hot flash or gastric discomfort. The VAS improvement rate for patients being orally administered both TJ-18 and TJ-3022 was 76.5±27.7% (mean±standard deviation). The additional TJ-3022 dose was 1.0-5.0 g/day. Twelve (12) patients have been treated without serious adverse reactions. CONCLUSIONS TJ-18 and TJ-3022 combination treatment is a promising means of treating intractable PHN, which has a self-reported tendency to aggravate pain under cold stimulation.

Abstract
AIM OF THE STUDY Our previous studies indicated that processed Aconiti tuber (PAT), a traditional Chinese herbal medicine, had antinociceptive effects and inhibitory effects on morphine tolerance by activation of kappa-opioid receptor (KOR). Preclinical studies also demonstrated that KOR agonists functionally attenuate addictive behaviors of morphine, such as conditioned place preference (CPP). Therefore, we hypothesize that PAT may inhibit morphine-induced CPP in rats. MATERIALS AND METHODS (1) Five groups of rats (n=8 for each group) were alternately subcutaneous (s.c.) injected with morphine 10mg/kg (one group receive normal saline as a control) and normal saline for 8 days and oral co-administrated with distilled water or PAT 0.3, 1.0, or 3.0 g/kg daily on days 2-9 during CPP training, respectively. (2) Other four groups of rats were randomly s.c. injected with nor-binaltorphimine (nor-BNI; 5mg/kg) or normal saline (as a control) 120 min before alternately s.c. with morphine and normal saline and oral co-administrated with distilled water or PAT 3.0 g/kg daily. Each rat was acquired pre-conditioning and post-conditioning CPP data and assayed dynorphin concentrations by radioimmunoassay in rat's nucleus accumbens (NAc) after CPP training. RESULTS (1) PAT 1.0 or 3.0 g/kg dose-dependently decreased the morphine-induced increase of CPP scores. (2) Nor-BNI completely antagonized the inhibition of PAT on morphine-induced CPP. (3) PAT dose-dependently increased dynorphin content in rats' NAc after CPP training. CONCLUSIONS (1) PAT dose-dependently inhibited morphine-induced CPP. (2) The inhibition of PAT on morphine-induced CPP was probably due to activation of KOR by increasing dynorphin release in rats' NAc.

Abstract
Pentazocine is a widely used mixed agonist-antagonist opioid. Previous animal studies have demonstrated that pentazocine-induced antinociception displayed a ceiling effect characterized by biphasic dose response with a increasing and then descending analgesia like a bell-shaped curve. This study attempted to clarify the mechanisms underlying such dose-response relationships. ddY and C57BL/6J mice received subcutaneous injection of saline or pentazocine (3, 10, 30, 56, or 100 mg · kg(-1)), at 120 min after subcutaneous injection of saline, a μ-opioid receptor antagonist clocinnamox mesylate (C-CAM) (5 mg · kg(-1)), a κ-opioid receptor antagonist nor-binaltorphimine (nor-BNI) (10 mg · kg(-1)), or the combination of C-CAM and nor-BNI. The antinociceptive effects of pentazocine were evaluated using tail pressure, hot plate, tail flick, and acetic acid writhing tests. Without pretreatment with an opioid receptor antagonist, the antinociceptive effects of pentazocine exhibited biphasic bell-shaped dose-response curves peaking at 30 mg · kg(-1). C-CAM completely and partly antagonized the antinociception induced by pentazocine at low (3-30 mg · kg(-1)) and high (56-100 mg · kg(-1)) doses, respectively. nor-BNI enhanced the antinociception by pentazocine at high doses and turned the later descending portion of the biphasic dose-response curves into a sigmoid curve. The combination of C-CAM and nor-BNI completely abolished the antinociception by pentazocine at all doses. Our results suggest pentazocine produces antinociception primarily via activation of μ-opioid receptors, but at high doses, this μ-opioid receptor-mediated antinociception is antagonized by concomitant activation of κ-opioid receptors. This provides the first reasonable hypothesis to explain the ceiling effects of pentazocine analgesia characterized by a biphasic dose response.

Abstract
As a non-selective agonist of opioid receptors, morphine can also act on the kappa-opioid receptor (KOR) when activating the mu-opioid receptor (MOR) and delta-opioid receptor (DOR). Although previous findings indicate that KOR plays an important role in morphine analgesia and antinociceptive tolerance, the reasons for the paradoxical functions of KOR in analgesia and anti-analgesia responses are still unclear. The aim of this study was to explore the role of the KOR in morphine analgesia and antinociceptive tolerance. As such, the changes in KOR expression in different regions of the nervous system in morphine tolerant rats were examined. We were able to attain morphine tolerance in rats via subcutaneous injection of morphine (10 mg/kg) twice daily for 7-consecutive days. Competitive real-time PCR, immunohistochemistry, and Western blot analyses were used to assess KOR expression in related regions of the nervous system, including the thalamus, hypothalamus, hippocampus, locus ceruleus (LC), periaqueductal gray (PAG), lumber-sacral spinal cord, and dorsal root ganglia (DRG). The expression of KOR increased in the locus ceruleus and spinal cord, but was significantly decreased in the DRG of morphine tolerant rats (P<0.05). No other significant changes in KOR expression were observed in the other regions. Consequently, we propose that the locus ceruleus and spinal cord are likely the dominant CNS regions and the DRG is the main peripheral site in which chronic morphine exerts its effect on KOR. Prolonged morphine administration induces inconsistent changes of KOR in the central and peripheral nervous system.

Abstract
BACKGROUND An isoindoline derivative, JM-1232(-) was developed as a sedative and analgesic drug. We performed the present study to investigate its antinociceptive effects on three different nociceptions in mice. METHODS Mail ddY mice were administered intraperitoneal (i.p.) JM-1232(-) 1,3 or 10 mg/kg (n = 8 for each dose in each test). Saline was used as a control. The hotplate or tail pressure test was performed for 120 min after i.p. drug injection. Acetic acid 0.6% solution in 10 mL/kg was i.p. administered 15 min after i.p. drug injection in the acetic acid test. The number of abdominal constriction episodes was counted for 10 min, starting 5 min after i.p. administration of the acid. When the analgesic effect was observed, naloxone or flumazenil was subcutaneously administered before administration of the maximum effective dose of JM-1232(-). Using the wheel running test, the number of wheel revolutions was recorded every 5 min for 120 min. RESULTS In the hotplate, tail pressure and acetic acid tests, i.p. JM-1232(-) produced significant antinociceptive effects with a 50% effective dose of 2.96 mg/kg (CI: 2.65-3.30 mg/kg), 3.06 mg/kg (CI: 2.69-3.47 mg/kg) and 2.27 mg/kg (CI: 1.46-3.53 mg/kg), respectively. In all tests, JM-1232(-)-induced antinociception was antagonized by flumazenil (5 mg/kg) but not by naloxone (10 mg/kg). In the running wheel test, there was no dose-dependent effect of JM-1232(-) on locomotor activity. CONCLUSION Systemically administered JM-1232(-) had antinociceptive effects on acute thermal, mechanical-induced pain, and visceral pain in mice. These effects might be mediated by benzodiazepine-gamma-aminobutyric acid type A receptors but not by opioid receptors.

Abstract
Antinociceptive effects of systemically administered midazolam remain controversial. The present study was performed to investigate its antinociceptive effects on different types of nociception in mice. Four different doses of midazolam (1, 3, 10, and 30 mg/kg) were administered intraperitoneally (i.p.). Saline was used as a control. The hot plate test, tail pressure test, acetic acid writhing test, the running wheel test, and the balance beam test were performed following the drug administration. In the hot plate test and tail pressure test, i.p. midazolam produced significant antinociceptive effects with the 50% effective dose (ED(50)) of 3.46 mg/kg [confidence interval (CI), 1.99 - 6.01 mg/kg] and 3.52 mg/kg (CI, 2.77 - 4.47 mg/kg), respectively. In the acetic acid writhing test, i.p. midazolam also produced significant antinociceptive effects. In the running wheel test, no mice stopped running after saline or midazolam at 1, 3, or 10 mg/kg, but all mice stopped running 30 and 45 min after i.p. administration of midazolam at 30 mg/kg. In the balance beam test, 30 min after i.p. administration of saline or midazolam at 1, 3, and 10 mg/kg, all mice were able to stay on the beam for 90 s, none of them could with midazolam at 30 mg/kg. In conclusion, systemically administered midazolam had antinociceptive effects on acute thermal, acute mechanical, and acute inflammatory-induced nociception in mice. The antinociceptive potency of midazolam was the same for both acute thermal-induced nociception and mechanical-induced nociception.

Abstract
AIM OF THE STUDY In this study, we investigated the effects of processed Aconiti tuber (PAT), an oriental herbal medicine, at analgesic doses on acute morphine antinociception in morphine-naïve mice and morphine tolerance in morphine-tolerant mice. MATERIALS AND METHODS In acute experiments, mice received subcutaneous (s.c.) morphine (2, 5, or 10 mg/kg) and oral distilled water or PAT (0.3, 1.0, or 3.0 g/kg). The mechanical nociceptive threshold (MNT) and thermal nociceptive latency (TNL) were measured with the tail pressure test and tail flick test, respectively, before, and at 30, 60, 90, and 120 min after s.c. morphine injection. In chronic experiments, mice received s.c. morphine (10 mg/kg) and oral distilled water or PAT (0.3, 1.0, or 3.0 g/kg) once daily for 11 days. MNT was measured before, and at 60 min after, and TNL was measured before, and at 30 min after, daily morphine injections on days 1-11. RESULTS PAT at analgesic doses inhibited the acute antinociceptive effect of morphine dose-dependently in morphine-naïve mice. In contrast, PAT at analgesic doses potentiated the chronic antinociceptive effect of morphine dose-dependently by inhibiting the development of morphine tolerance dose-dependently. These effects of PAT on acute and chronic morphine antinociception were mediated through activation of kappa-opioid receptors. CONCLUSIONS These results indicated that chronic co-administration of PAT at analgesic doses with morphine could provide better-maintained morphine analgesia in a long-term morphine treatment after initial inhibition of acute morphine antinociception for a brief period of time.

Abstract
In the previous studies, we demonstrated that an oriental herbal medicine, processed Aconiti tuber (PAT), at subanalgesic doses could inhibit or reverse the antinociceptive tolerance to morphine. In the present study, we compared the effect of PAT, trans-(+/-)-3,4-dichloro-N-methyl-N-(2-(1-pyrrolidin)cyclohexyl)-benzeneacetamide methane sulfonate hydrate (U50488H), a selective kappa opioid receptor (KOR) agonist, and (-)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine-maleate (MK-801), a N-methyl-D-aspartate (NMDA) receptor antagonist, on the antinociceptive tolerance to morphine in the same experimental condition. Mice received subcutaneous morphine (10 mg/kg), and oral PAT at a subanalgesic dose (0.3 g/kg for mechanical or 1.0 g/kg for thermal test), or intraperitoneal U50488H at a subanalgesic dose (3 mg/kg), or MK-801 at a subanalgesic dose (0.1 mg/kg) once daily for 14 days. The mechanical nociceptive threshold was measured before, and at 60 min by tail pressure testing, and thermal nociceptive latency was measured before, and at 30 min by hot plate testing, after daily morphine injections. PAT and U50488H could not only inhibit the development of morphine tolerance but also reverse the already-developed morphine tolerance, while MK-801 could only inhibit the development of morphine tolerance but not reverse the already-developed morphine tolerance, in both mechanical and thermal nociceptive tests. These data suggested that PAT, an indirect-acting KOR agonist, share the common pharmacological property of KOR agonists on morphine tolerance, and that PAT may be superior to some NMDA receptor antagonists which do not reverse already-developed morphine tolerance.

In the previous studies, we demonstrated that an oriental herbal medicine processed Aconiti tuber (PAT) at subanalgesic doses could inhibit the development of mechanical antinociceptive tolerance to morphine using the tail pressure test. In the present study, we evaluated whether PAT could inhibit thermal antinociceptive tolerance to morphine using the high temperature (55 degrees C) hot plate test. Mice received subcutaneous morphine (10mg/kg), and oral PAT at doses that did not inhibit the hot plate response (0.3, 0.5, 1.0, and 2.0 g/kg), once daily for 14 days. The thermal nociceptive latency was measured at 30 min after daily morphine injections. Compared with placebo, oral PAT partially and dose-dependently inhibited the development of morphine tolerance in morphine-naïve mice, and reversed already-developed morphine tolerance in morphine-tolerant mice. These data suggested that PAT at subanalgesic doses could dose-dependently inhibit and reverse thermal antinociceptive tolerance to morphine.
