Effect of Kvass on Improving Functional Dyspepsia in Rats. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:5169892. [PMID: 35799630 PMCID: PMC9256358 DOI: 10.1155/2022/5169892] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Accepted: 05/20/2022] [Indexed: 11/23/2022]
Abstract
Functional dyspepsia (FD) is a common digestive system disease, and probiotics in the treatment of FD have a good curative effect. Patients with gastrointestinal diseases often show a poor response to traditional drug treatments and suffer from adverse reactions. Kvass can be used as a functional drink without side effects to improve the symptoms of FD patients. The results showed that compared with those of the model group, the body weight and food intake of the treatment group were significantly increased (P < 0.05), and the gastric residual rate of the treatment group was significantly decreased (P < 0.05); the amount of pepsin in the treatment group was significantly higher than that in the model group (P < 0.05); a high dose of Kvass could increase the contents of ghrelin, motilin (MTL), and gastrin (GAS) in the plasma and decrease the contents of vasoactive intestinal peptide (VIP) in the plasma; the contents of ghrelin, MTL, and GAS in the gastric antrum were also increased in the high-dose group. Kvass beverage can significantly improve the gastrointestinal function of rats, which may be because it can improve the contents of ghrelin, MTL, GAS, and VIP in both the serum and gastric antrum by regulating the expression of short-chain fatty acids in the colon.

Int J Biol Macromol 2022; 199:24-35. [PMID: 34973271 DOI: 10.1016/j.ijbiomac.2021.12.109] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 11/21/2021] [Accepted: 12/18/2021] [Indexed: 12/12/2022]
Abstract
An arabinan-rich acidic polysaccharide, named ALP4-2 ([α]20 D = +197.8 (c 1.0 mg/mL, H2O); and Mw = 5.59 × 103 g/mol), was obtained from Atractylodes lancea (Thunb.) DC. ALP4-2 is mainly comprised of Ara along with a small amount of GalA, Gal, Rha, Glc and Xyl. The structure was decorated by glycosidic linkages of α-Araf-(1→, →3)-α-Araf-(1→, →5)-α-Araf-(1→, →3,5)-α-Araf-(1→, →2,4)-α-Rhap-(1→, α-GalAp-(1→, →4)-α-GalAp-6-OMe-(1→, →4)-α-GalAp-6-OMe and β-Galp-(1→ with a ratio of 6:1:7:5:5:1:7:1:4. The structure, configuration and microstructure of ALP4-2 was proposed by comprehensive considerations of results from SEC-MALLS-RID, SEC-HRMS, GC-MS, and 1D/2D NMR spectroscopy. Except for a high methyl ester in full pectin regions, an abundant arabinan moiety is observed in ALP4-2 with highly complex and branched characteristics. The immunoactivity displayed that ALP4-2 can significantly promote phagocytosis of macrophage without cytotoxicity, and stimulate nitric oxide and cytokines (TNF-α, IL-6 and IL-10) release on RAW 264.7.

Abstract
Diabetes mellitus (DM) is one of the most important metabolic disorders associated with chronic hyperglycemia and occurs when the body cannot manage insulin secretion, insulin action, or both. Autoimmune destruction of pancreatic beta cells and insulin resistance are the major pathophysiological factors of types 1 and 2 of DM, respectively. Prolonged hyperglycemia leads to multiple organs dysfunctions, including nephropathy, neuropathy, cardiomyopathy, gastropathy, and micro- and macrovascular disorders. The basis of the metabolic abnormalities in carbohydrate, fat, and protein in diabetes is insufficient action of insulin on various target tissues. Medicinal plants are rich sources of bioactive chemical compounds with therapeutic effects. The beneficial effects of leaves, fruits, and flowers extracts of Crataegus oxyacantha, commonly called hawthorn, belonging to the Rosaceae family, are widely used as hawthorn-derived medicines. Data in this review have been collected from the scientific articles published in databases such as Science Direct, Scopus, PubMed, Web of Science, and Scientific Information Database from 2000 to 2021. Based on this review, hawthorn extracts appear both therapeutic and protective effects against diabetic-related complications in various organs through molecular mechanisms, such as decreasing triglyceride, cholesterol, very low density lipoprotein and increasing the antioxidant activity of superoxide dismutase, catalase, glutathione peroxidase, total antioxidant capacity, decreasing malondialdehyde level, and attenuating tumor necrosis factor alpha, interleukin 6 and sirtuin 1/AMP-activated protein kinase (AMPK)/nuclear factor kappa B (NF-κB) pathway and increasing the phosphorylation of glucose transporter 4, insulin receptor substrate 1, AKT and phosphoinositide 3-kinases, and attenuating blood sugar and regulation of insulin secretion, insulin resistance, and improvement of histopathological changes in pancreatic beta cells. Collectively, hawthorn can be considered as one new target for the research and development of innovative drugs for the prevention or treatment of DM and related problems.

Abstract
BACKGROUND Atractylodes chinensis (family Asteraceae) is a perennial herb with many pharmacological effects. OBJECTIVE Extraction of volatile oil from Atractylodes chinensis was optimized and its hypoglycemic activities were studied. METHODS Enzymolysis-microwave-assisted hydrodistillation (EMAHD) was adopted to extract the volatile oil, and the technology was optimized using a single-factor experiment that incorporated response surface methodology (RSM). The extraction rates of volatile oil by EMAHD, microwave-assisted hydrodistillation (MAHD), and hydrodistillation (HD) methods were compared at different times. The ingredients of Atractylodes chinensis volatile oil were analyzed by gas chromatography-mass spectrometry. Scanning electron microscopy (SEM) were used to analyze the microstructural changes in Atractylodes chinensis residue before and after extraction. The inhibition of α-amylase activity was determined. RESULTS The obtained optimal extraction conditions for EMAHD were as follows: enzyme concentration 1.6%, pH 7, enzymolysis time 20 min, enzymolysis temperature 50°C, liquid-solid ratio 30:1, microwave power 455 W, and microwave time 40 min. The levels of the main ingredients and the in vitro inhibition of α-amylase activities were higher for Atractylodes chinensis volatile oil extracted by EMAHD than by HD or MAHD. The powder residue of Atractylodes chinensis remaining after EMAHD showed a ruptured and collapsed cell structure, indicating accelerated dissolution of the volatile oil. CONCLUSIONS AND HIGHLIGHTS EMAHD is deemed a method with many advantages for extraction of volatile oil from Atractylodes chinensis. The volatile oil of Atractylodes chinensis is a promising component for treating hyperglycemia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Artemisia biennis Willd. (Dermane in Persian) has been used as an antinociceptive remedy in Iranian folkloric medicine. OBJECTIVE The aim of the present study was to evaluate the anti-nociceptive effects of Artemisia biennis Willd. aerial part essential oil (ABAEO) on male Swiss mice. MATERIALS AND METHODS Nociceptive pain techniques including acetic acid-induced writhing (AAIW), formalin-induced paw licking (FPL), glutamate-induced paw licking (GPL), and tail-flick (TF) models were applied. We assessed opioid and L-arginine-NO-cGMP-KATP pathways to detect the possible anti-nociceptive properties of ABAEO. In addition, neuropathic pain was induced by the cervical spinal cord contusion model. RESULTS ABAEO (120 mg/kg) had a significant anti-nociceptive activities in comparison to the control animals (p < 0.05) in the AAIW, TF, GPL, and FPL assays. The selective opioid antagonist (naloxonazine) administration in the AAIW test alleviated the anti-nociceptive effect of ABAEO (p < 0.05). L-arginine, methylene blue, and glibenclamide treatment prevented the ABAEO anti-nociceptive effects (p < 0.05); however, sodium nitroprusside could profoundly potentiate the ABAEO-associated antinociception in the FPL (phase II) test (p < 0.05). In nociceptive pain models, Cr (one of the main constituents of ABAEO) showed significant anti-nociceptive effects (p < 0.05). Moreover, the von Frey results indicated that ABAEO could attenuate mechanical allodynia in mice. CONCLUSION Our observation revealed the anti-nociceptive effects of ABAEO in male mice. These effects could include, at least in part, modulating glutamatergic mechanisms via opioid systems. Our data output also indicates activating the L-arginine-NO-cGMP-KATP system in ABAEO anti-nociceptive activities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atractylodis Rhizoma (AR), mainly includes Atractylodes lancea (Thunb.) DC. (A. lancea) and Atractylodes chinensis (DC.) Koidz. (A. chinensis) is widely used in East Asia as a diuretic and stomachic drug, for the treatment of rheumatic diseases, digestive disorders, night blindness, and influenza as it contains a variety of sesquiterpenoids and other components of medicinal importance. AIM OF THE REVIEW A systematic summary on the botany, traditional uses, phytochemistry, pharmacology, toxicology, and quality control of AR was presented to explore the future therapeutic potential and scientific potential of this plant. MATERIALS AND METHODS A review of the literature was performed by consulting scientific databases including Google Scholar, Web of Science, Baidu Scholar, Springer, PubMed, ScienceDirect, CNKI, etc. Plant taxonomy was confirmed to the database "The Plant List". RESULTS Over 200 chemical compounds have been isolated from AR, notably sesquiterpenoids and alkynes. Various pharmacological activities have been demonstrated, especially improving gastrointestinal function and thus allowed to assert most of the traditional uses of AR. CONCLUSIONS The researches on AR are extensive, but gaps still remain. The molecular mechanism, structure-activity relationship, potential synergistic and antagonistic effects of these components need to be further elucidated. It is suggested that further studies should be carried out in the aspects of comprehensive evaluation of the quality of medicinal materials, understanding of the "effective forms" and "additive effects" of the pharmacodynamic substances based on the same pharmacophore of TCM, and its long-term toxicity in vivo and clinical efficacy.

Abstract
We aim to investigate the relationship between serum somatostatin (SST) levels and glucose-lipid metabolism at various stages of glucose tolerance in the Jino ethnic minority (n=111) and Han population (n=113) of Yunnan Province, southwest China. Anthropometric parameters and biochemical traits were measured. Serum SST and plasma glucagon levels were tested. Participants were divided into three subgroups: isolated fasting hyperglycemia (IFH), isolated post challenge hyperglycemia (IPH) and normal glucose tolerance (NGT). SST levels were found lower while glucagon levels were significantly higher in the Jino ethnic with IPH (P=0.0026 and P=0.0069, respectively). Fasting glucose and high density lipoprotein-cholesterol (HDL-C) levels were higher (P=0.0055 and P=0.0021, respectively) and fasting insulin levels and homeostasis model assessments β-cell function were lower (P=0.0479 and P=0.0007, respectively) in the Jino population. After adjusting for confounding factors, the serum SST level was associated with glucagon (P<0.0001) in both populations. The SST level was correlated with fasting Cpeptide (P=0.0267) in Jino and HDL-C levels in Han (P=0.0079). Our findings suggest that serum SST levels and plasma glucagon levels may vary in subjects with IPH between two ethnics.

Abstract
Functional dyspepsia (FD) is a common functional gastrointestinal disorder with pain or discomfort in the upper abdomen as the main characteristic. The prevalence of FD worldwide varies between 5% and 11%. This condition adversely affects attendance and productivity in the workplace. Emerging evidence is beginning to unravel the pathophysiologies of FD, and new data on treatment are helping to guide evidence-based practice. In order to better understand the pathophysiologies of FD and explore better treatment options, various kinds of animal models of FD have been developed. However, it is unclear which of these models most closely mimic the human disease. This review provides a comprehensive overview of the currently available animal models of FD in relationship to the clinical features of the disease. The rationales, methods, merits, and disadvantages for modelling specific symptoms of FD are discussed in detail.

Abstract
AIM To establish a rat model of anxiety-like gastric hypersensitivity (GHS) of functional dyspepsia (FD) induced by novel sequential stress.
METHODS Animal pups were divided into two groups from postnatal day 2: controls and the sequential-stress-treated. The sequential-stress-treated group received maternal separation and acute gastric irritation early in life and restraint stress in adulthood; controls were reared undisturbed with their mothers. Rats in both groups were followed to adulthood (8 wk) at which point the anxiety-like behaviors and visceromotor responses to gastric distention (20-100 mmHg) and gastric emptying were tested. Meanwhile, alterations in several anxiety-related brain-stomach modulators including 5-hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), brain-derived neurotrophic factor (BDNF) and nesfatin-1 in the rat hippocampus, plasma and gastric fundus and the 5-HT1A receptor (5-HT1AR) in the hippocampal CA1 subfield and the mucosa of the gastric fundus were examined.
RESULTS Sequential-stress-treated rats simultaneously demonstrated anxiety-like behaviors and GHS in dose-dependent manner compared with the control group. Although rats in both groups consumed similar amount of solid food, the rate of gastric emptying was lower in the sequential-stress-treated rats than in the control group. Sequential stress significantly decreased the levels of 5-HT (51.91 ± 1.88 vs 104.21 ± 2.88, P < 0.01), GABA (2.38 ± 0.16 vs 5.01 ± 0.13, P < 0.01) and BDNF (304.40 ± 10.16 vs 698.17 ± 27.91, P < 0.01) in the hippocampus but increased the content of nesfatin-1 (1961.38 ± 56.89 vs 1007.50 ± 33.05, P < 0.01) in the same site; significantly decreased the levels of 5-HT (47.82 ± 2.29 vs 89.45 ± 2.61, P < 0.01) and BDNF (257.05 ± 12.89 vs 536.71 ± 20.73, P < 0.01) in the plasma but increased the content of nesfatin-1 in it (1391.75 ± 42.77 vs 737.88 ± 33.15, P < 0.01); significantly decreased the levels of 5-HT (41.15 ± 1.81 vs 89.17 ± 2.31, P < 0.01) and BDNF (226.49 ± 12.10 vs 551.36 ± 16.47, P < 0.01) in the gastric fundus but increased the content of nesfatin-1 in the same site (1534.75 ± 38.52 vs 819.63 ± 38.04, P < 0.01). The expressions of 5-HT1AR in the hippocampal CA1 subfield and the mucosa of the gastric fundus were down-regulated measured by IHC (Optical Density value: Hippocampus 15253.50 ± 760.35 vs 21149.75 ± 834.13; gastric fundus 15865.25 ± 521.24 vs 23865.75 ± 1868.60; P < 0.05, respectively) and WB (0.38 ± 0.01 vs 0.57 ± 0.03, P < 0.01) (n = 8 in each group).
CONCLUSION Sequential stress could induce a potential rat model of anxiety-like GHS of FD, which could be used to research the mechanisms of this intractable disease.

Abstract
Treatment and control of cholangiocarcinoma (CCA): the bile duct cancer is limited by the lack of effective chemotherapeutic drugs and alternative drugs are needed, particularly those from natural sources. This article reviews steps of research and development of Atractylodes lancea (Thunb) DC. (AL) as potential candidate for CCA chemotherapy, with adoption of the reverse pharmacology approach. Major steps include (1) reviewing of existing information on its phytochemistry and pharmacological properties, (2) screening of its activities against CCA, (3) standardization of AL, (4) nonclinical studies to evaluate anti-CCA activities, (5) phytochemistry and standardization of AL extract, (6) development of oral pharmaceutical formulation of standardized AL extract, and (7) toxicity testing of oral pharmaceutical formulation of standardized AL extract. Results from a series of our study confirm anti-CCA potential and safety profiles of both the crude extract and the finished product (oral pharmaceutical formulation of the standardized AL extract). Phases I and II clinical trials of the product to confirm tolerability and efficacy in healthy subjects and patients with advanced stage CCA will be carried out soon.

Abstract
Atractylodin is one of the main constituents in the rhizomes of Atractylodes lancea Thunb., being capable of treating cancer cachexia-anorexia and age-related diseases as an agonist of growth hormone secretagogue receptor (GHSR). GHSR was herein expressed in human gastric smooth muscle cells (HGSMCs) and activated by ghrelin receptor agonist L-692,585. Like L-692,585, atractylodin also increased Ca2+ and enhanced the phosphorylation of myosin light chain (MLC) through GHSR in HGSMCs. In addition, atractylodin promoted gastric emptying and MLC phosphorylation in the gastric antrum of mice also through GHSR. Collectively, atractylodin can activate GHSR in gastric smooth muscle, as a potential target in clinical practice.

Abstract
Atractylodin is one of the major constituents of the rhizome of Atractylodes lancea, which is widely used in Korean traditional medicine as a remedy for the treatment of gastritis and gastric ulcers. Despite of a major constituent of widely used botanical to treat inflammatory responses little is known about anti-inflammatory effect of atractylodin in the human mast cell (HMC-1). Hence, we evaluated the effect of atractylodin on the release of IL-6, the involvement of nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) and mitogen-activated protein kinases (MAPKs) in phorbol-12-myristate-13-acetate and A23187-induced HMC-1. In addition, Janus kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3), phospholipase C (PLC) gamma 1, and AKT phosphorylation relevant to NPM-ALK signal pathway were assessed. IL-6 levels in the HMC-1 stimulated by phorbol-12-myristate-13-acetate and A23187 were apparently decreased by the treatment of atractylodin. Concurrently, atractylodin not only inhibited the phosphorylation of NPM-ALK, but also suppressed the phosphorylation of JAK2, STAT3, PLC gamma 1, and AKT. Furthermore, the activated mitogen-activated protein kinases (MAPKs) by phorbol-12-myristate-13-acetate and A23187 were inhibited by atractylodin. These results suggested that atractylodin might have a potential regulatory effect on inflammatory mediator expression through blockade of both the phosphorylation of MAPKs and the NPM-ALK signaling pathway.

Abstract
BACKGROUND Many screening procedures for agents with potential usefulness in functional dyspepsia (FD) rely on animals exposed to stress early in life (neonatal maternal separation, NMS) or in adulthood (restraint stress, RS). PURPOSE Since many clinical cases of FD have been associated with stress in early life followed by stress in adulthood, a sequential model simulating the clinical situation is described. To explore the validity of the model, the efficacy of STW5, a multicomponent herbal preparation of proven usefulness in FD, was tested. STUDY DESIGN/METHODS A sequential stress model established where rats are exposed to NMS after birth followed later by RS in adulthood. Stress hormones and ghrelin were measured in plasma, while responsiveness of stomach fundus strips to smooth muscle stimulants and relaxants was assessed ex-vivo. The effectiveness of treatment with STW5 a few days before and during exposure to RS in preventing changes induced by the stress model is reported and compared to its efficacy when used in animals subjected to RS alone. RESULTS Responses to both stimulants and relaxants were reduced to various extents in the studied models, but treatment with STW5 tended to normalize gastric responsiveness. Plasma levels of ghrelin, corticosterone releasing factor, and corticosterone were raised by RS as well as the sequential model. Treatment with STW5 tended to prevent the deranged parameters. CONCLUSION The sequential stress model has a place in drug screening for potential usefulness in FD as it simulates more the clinical setting. Furthermore, the findings shed more light on the mechanisms of action of STW5 in FD.

Abstract
The rhizome of Atractylodes lancea (A. lancea) (Thunb.) DC. (AL) is extensively used in Chinese, Thai, and Japanese traditional medicines as crude extracts/decoctions or a component in various herbal formulations. Various pharmacological activities of AL and its major constituents have been demonstrated in vitro, ex vivo, and in animal models. Results from the toxicity studies in animal models suggest safety profile of AL and its active constituents. Despite extensive use with positive impression in many diseases, there has not been a clinical study that can conclusively support its efficacy and safety profile in human. This review comprehensively summarizes current information on the pharmacological activities of AL and their active constituents including anticancer, anti-inflammatory, antimicrobial and antipyretic activities, as well as activities on central nervous, cardiovascular, and gastrointestinal systems.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hoodia gordonii (Masson) Sweet ex Decne (family Apocynaceae) is consumed globally as a natural appetite suppressant. While this effect-and its subsequent effect of weight loss-has been reported in the scientific literature, no information is available on the specific tissue types affected that accounts for the significant weight loss reported after consumption of the plant. Furthermore, most studies are performed on lean animals, so that the response of overweight or obese individuals to this plant supplement remains largely unknown. MATERIALS AND METHODS Twelve lean and twelve obese male Wistar rats were supplemented with different doses of Hoodia gordonii extract (80 or 160 mg/kg body mass twice daily) in a placebo-controlled study, for a period of 14 days. RESULTS All supplemented rats exhibited significant weight loss (P<0.001). This could be ascribed to decrease in both adipose cell size and skeletal muscle fibre size. CONCLUSIONS We conclude that the weight loss seen after consumption of Hoodia gordonii is due to loss of both adipose and muscle mass.

Abstract
AIM: To assess the efficacy of psychological language combined with gastric pacing (GP) for treating functional dyspepsia (FD).
METHODS: Sixty patients with FD diagnosed according to the Rome III criteria were randomly divided into a combination treatment group (n = 30) and a GP group (n = 30). All patients were placed in a quiet environment. The combination treatment group received psychological language and gastric pacing synchronization output, and the voice ran throughout the treatment to guide gastric electrical pacing. The GP group underwent GP only. The treatment (20 min each) was given once daily for seven consecutive days. Researcher-rated symptom scores and patients' self-rated symptom scores (both overall and individual symptom scores) were calculated to assess clinical efficacy before and after treatment. Clinical efficacy was compared between the two groups of subjects.
RESULTS: Researcher-rated symptom scores and patients' self-rated symptom scores decreased in both groups after treatment. Compared to the GP group, the combination treatment group had more significantly decreased researcher-rated overall symptom score (4.033 ± 1.903 vs 1.700 ± 1.579, t = 5.169, P < 0.05), postprandial bloating (0.967 ± 0.850 vs 0.533 ± 0.776, t = 2.062, P < 0.05), early satiety (0.933 ± 0.785 vs 0.300 ± 0.466, t = 3.800, P < 0.05), upper abdominal pain (0.900 ± 0.759 vs 0.400 ± 0.563, t = 2.898, P < 0.05), abdominal burning sensation (0.700 ± 0.702 vs 0.300 ± 0.535, t = 2.482, P < 0.05), and nausea (0.533 ± 0.776 vs 0.200 ± 0.407, t = 2.482, P < 0.05), scores. The overall response was significantly higher in the combination treatment group than in the GP group (96.7% vs 70.0%, χ2 = 7.68, P < 0.05). Compared to the GP group, the combination treatment group also had more significantly decreased self-rated overall symptom score (12.633 ± 5.714 vs 6.767 ± 4.232, t = 4.519, P < 0.05), postprandial bloating (3.200 ± 2.188 vs 2.100 ± 1.729, t = 2.161, P < 0.05), early satiety (2.633 ± 2.025 vs 1.500 ± 0.563, t = 2.461, P < 0.05), upper abdominal pain (2.567 ± 1.942 vs 1.267 ± 1.437, t = 2.948, P < 0.05), abdominal burning sensation (2.500 ± 2.403 vs 1.033 ± 1.189, t = 2.996, P < 0.05), and nausea scores (1.733 ± 1.946 vs 0.833 ± 1.177, t = 2.167, P < 0.05). The overall response was significantly higher in the combination treatment group than in the GP group (90.0% vs 80.0%, χ2 = 1.18, P < 0.05).
CONCLUSION: Psychological language combined with GP is more effective than GP alone in the treatment of FD, and is a new option for non-drug treatment of FD.

Abstract
Depression could hardly get a satisfactory effect from the currently available antidepressants. To get a more effective treatment, antidepressant effect and monoaminergic mechanism of Fructus Aurantii (FRA) in the rat forced swimming test (FST) and open field test (OFT), and its prokinetics were examined. FST and OFT were respectively used to evaluate the antidepressant effect and locomotor activity of FRA. We observed the effects of monoamine receptor antagonists on FRA-induced antidepressant effect in rat. The effects of FRA on intestinal transit, gastric emptying and in vitro jejunum contractile activity were assessed. FRA decreased significantly the immobility time (32.6±8.5, 30.3±5.2 vs 56.4±9.4, all p<0.01) in FST, dose-dependent increased the locomotor activity (102±17.5, 120±18.5 vs 89±9.8, p<0.05 or 0.01), significantly accelerated gastric emptying (GE: 48.1±6.3, 39.5±5.7 vs 19.5±3.8, p<0.01) and intestinal transit (IT: 67.3±9.1, 64.2±6.3 vs 49.1±8.2, p<0.01) of the semi-liquid meal, compared with vehicle. And FRA (1 μM, 10 μM) significantly increased the mean amplitude (0.24±0.021 and 0.281±0.015) of contraction in jejunum of rat compared with vehicle (0.149±0.011) in vitro. FRA (10 μM) could induce a largest amplitude (0.281±0.015) of contraction in jejunum. The anti-immobility effect of FRA in FST was prevented by pre-treatment of rat with p-chlorophenylalanine methyl ester, WAY100635, ketanserin, haloperidol, SCH233390, sulpiride, yohimbine, but not prazosin. FRA could simultaneously induce prokinetics and antidepressant effect, deserves further to investigate.

Abstract
AIM OF THE STUDY The rhizomes of Atractylodes lancea DC (Compositae) are used clinically to treat gastrointestinal symptoms, including functional dyspepsia and gastroparesis, in China and Japan, but their influence and mechanism on gastrointestinal motility are not yet proven in detail. MATERIALS AND METHODS This study examined the effects of an Atractylodes lancea extract, and isolated β-eudesmol, on gastric emptying and small intestinal motility in atropine-, dopamine-, and 5-hydroxytryptamine (5-HT)-treated mice. RESULTS AND CONCLUSIONS The extract (500 or 1000mg/kg) and β-eudesmol (50 or 100mg/kg), as well as itopride hydrochloride (a dopamine D(2) receptor antagonist, 10 or 50mg/kg), stimulated small intestinal motility in normal mice. They inhibited reductions in gastric emptying and gastrointestinal motility induced by dopamine (1mg/kg, intraperitoneal injection, ip). The extract (1000mg/kg) and β-eudesmol (100mg/kg) inhibited the atropine-induced decrease in small intestinal motility, but not gastric emptying. Furthermore, the extract (500 or 1000mg/kg) and β-eudesmol (25, 50, or 100mg/kg) inhibited reductions in gastric emptying and small intestinal motility caused by 5-HT (4mg/kg, ip) or the 5-HT(3) receptor agonist 1-(3-chlorophenyl) biguanide (0.5mg/kg, ip), but not a 5-HT(2C) receptor agonist. These findings suggest that the extract of Atractylodes lancea and β-eudesmol may stimulate gastric emptying or small intestinal motility by inhibiting the dopamine D(2) receptor and 5-HT(3) receptor.

[PMID: 21811919 DOI: 10.1007/s12272-011-0710-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2009] [Revised: 11/20/2009] [Accepted: 11/26/2010] [Indexed: 11/29/2022]
Abstract
Heat stress (HS) may induce immunosuppression as well as inhibit the proliferation of lymphocytes. This study evaluated the effects on immune function of our prescription on splenic lymphocytes under HS as well as its compatibility. The effects of four herbal extracts from Agastache rugosa, Atractylodes lancea, Cortex Phellodendri, and Gypsum Fibrosum on heat treated splenic lymphocytes were investigated and the compatibility of the prescription was also explored by using the Taguchi method. This study revealed changes in proliferation by traditional Chinese medicines of splenic lymphocytes after HS. Proliferation in the HS group was significantly lower than the control group. Under HS, the effects of higher concentrations of Agastache rugosa (100 and 200 μg/mL), Atractylodes lancea (100 and 200 μg/mL), Cortex Phellodendri (50 and 100 μg/mL) and Gypsum Fibrosum (100 and 200 μg/mL) caused a significant increase on ConA/LPS-induced proliferation of lymphocytes than lower concentrations. We, therefore, conclude that the prescription of traditional Chinese medicines may recover splenic lymphocytes from the immunosuppression induced by HS. The Taguchi design, which allows rapid and high efficiency for the selection of the best conditions for our prescription on HS-treated splenic lymphocytes, demonstrated that Agastache rugosa (200 μg/mL), Atractylodes lancea (200 μg/mL), Cortex Phellodendri (100 μg/mL) and Gypsum Fibrosum (100 μg/mL) were the optimal conditions for the prescription. The validation experiment confirmed that our composition in optimum extraction conditions enhanced effects on ConA or LPS-stimulated lymphocytes under HS. The results showed that the Taguchi optimization approach is a suitable method for optimization of the composition of prescription.

Abstract
The rhizome of Atractylodes ovata De Candolle is rich in essential oils, which are usually removed by processing. In this study, anti-oxidative abilities of essential oils and aqueous extracts of A. ovata rhizome were explored, and the influence of processing on the anti-oxidative abilities was examined. Essential oils and aqueous extracts of A. ovata were extracted by boiling water and steam distillation, respectively. Quality of these two A. ovata samples was controlled by HPLC and GC-MS system, and anti-oxidative abilities were then evaluated. Results showed that surface color of A. ovata turned to brown and chemical components were changed by processing. Contents of both atractylon and atractylenolide II decreased in the essential oils, but only the contents of atractylon decreased by processing. Atractylenolide III increased in both A. ovata samples. However, A. ovata essential oils displayed stronger anti-oxidative abilities than aqueous extracts in DPPH-scavenging, TBH-induced lipid peroxidation and catalase activity assays. Moreover, the bioactivity of essential oils from raw A. ovata was stronger than oils from processed A. ovata. On the other hand, cytotoxicity of A. ovata essential oils was stronger than that of aqueous extracts, and was more sensitive on H9C2 cell than NIH-3T3 and WI-38 cells. In contrast, stir-frying processing method increased cytotoxicity of essential oils, but the cytotoxicity was ameliorated when processed with assistant substances. The results suggested that phytochemical components and bioactivity of A. ovata were changed after processing and the essential oils from raw A. ovata showed better anti-oxidative and fewer cytotoxicity effects.

Abstract
This experiment studied the potential effect of meranzin hydrate (MH) and decoction of herb Fructus Aurantii (FA) on rat gut motility. It also investigated the prokinetic mechanism of MH. Experiments were performed on male Sprague–Dawley rats (200–220 g). The study included: (1) qualitation of MH and four other known compounds in FA and jejunum after oral administration of FA decoction to rats; (2) in vitro experiment of MH on rat jejunum contractions; (3) in vivo experiment of FA and MH in rats. Dose-dependently, MH (1–100 μM) increased amplitude in longitudinal and circular jejunum muscles. Pretreatment of jejunum longitudinal strips with benzhydramine (1 μM) remarkably inhibited the contractions induced by histamine (1 μM) and MH (10 or 30 μM). Pretreatment of jejunum longitudinal strips with atropine (1 μM) reduced the contractions induced by acetylcholine (1 μM) but did not influence the contractions induced by MH (10 or 30 μM). Interestingly, the antagonism of benzhydramine to MH was also verified in vivo. MH can be absorbed into the jejunum following oral administration of FA decoction. In healthy rats, MH (7, 14, and 28 mg/kg) and FA (3.3, 10, and 20 g/kg) both promoted intestinal transit and gastric emptying in a dose-dependent manner when gavaged acutely. In cisplatin model rats, MH (14 and 28 mg/kg) significantly reversed cisplatin-induced delay in gastric emptying. Meranzin hydrate can induce similar effect to Fructus Aurantii on intestinal motility and it was, at least in part, mediated by stimulation of H1 histamine receptors.

Abstract
CONTEXT Hypertrophic scarring following surgical procedures, trauma and especially burns can lead to severe functional and cosmetic impairment, causing a decrease in the quality of life. Although a wide choice of treatments is offered, few therapeutic methods are universally accepted because of their side effects. OBJECTIVE The effects of the essential oil (EO) extracted from rhizomes of Ligusticum chuanxiong Hort. (Umbelliferae) in human hypertrophic scar fibroblasts (HSFs) are investigated for the first time. MATERIALS AND METHODS Chemical composition of hydrodistilled EO obtained from rhizomes of Ligusticum chuanxiong was analyzed by gas chromatography-mass spectrometry (GC-MS). The effects of EO on cell viability, apoptosis rate, mitochondrial membrane potential (MMP), lactate dehydrogenase (LDH), reactive oxygen species (ROS) and caspase-3 in HSFs were investigated. RESULTS The experimental results showed that EO significantly inhibited cell viability, elicited morphological changes and induced apoptosis in HSFs. EO also evidently increased the loss of MMP, the levels of LDH release and cellular ROS production, and the activity of caspase-3. DISCUSSION AND CONCLUSION EO-induced apoptosis was at least partially carried out via destruction of the intracellular antioxidant system and elicitation of excessive ROS accumulation in HSFs, which impaired mitochondrial membranes and elicited caspase-3 activation. EO could be an effective cure for human hypertrophic scar.

Abstract
Abstract
Objectives
The rhizome of Atractylodes ovata De Candolle is popularly used in traditional Chinese medicine to treat gastrointestinal diseases. However, the major gastroprotective compounds of A. ovata have not been identified. This study reports on the principal gastro- protective component of A. ovata.
Methods
Five sesquiterpenoids (atractylon, atractylenolides I, II, III and biatractylolide) were isolated from the extracts of A. ovata rhizome via silica gel column chromatography. The gastroprotective effects of these five sesquiterpenoids were measured in in-vitro ethanol-induced primary culture rat gastric mucosal (PRGM) cell damage and in-vivo ethanol-induced acute rat gastric ulcer models.
Key findings
Atractylon, atractylenolide I and biatractylolide were strongly toxic in PRGM cells, whilst atractylenolides II and III were not. Atractylenolide II did not show cytoprotective effects, but oral administration of atractylenolide III dose-dependently prevented ethanol-induced PRGM cell death and cell membrane damage. The EC50 values were 0.27 and 0.34 mm, respectively. In the in-vivo assay, atractylenolide III 10 mg/kg significantly reduced 70% ethanol-induced Wistar rat gastric ulcer. Atractylenolide III could inhibit matrix metalloproteinase (MMP)-2 and MMP-9 expression through upregulation of tissue inhibitors of metalloproteinase from the gastric ulcerated tissues.
Conclusions
Atractylenolide III was the major gastroprotective component of A. ovata in ethanol-induced acute gastric ulcer. It is suggested that the gastroprotective mechanism of atractylenolide III was via inhibition of the MMP-2 and MMP-9 pathway.

Abstract
Membranous glomerulonephritis (MGN) remains the most common cause of adult-onset nephrotic syndrome in the world and up to 40% of untreated patients will progress to end-stage renal disease. Although the treatment of MGN with immunosuppressants or steroid hormones can attenuate the deterioration of renal function, numerous treatment-related complications have also been established. In this study, the ameliorative effects of arctiin, a natural compound isolated from the fruits of Arctium lappa, on rat glomerulonephritis induced by cationic bovine serum albumin (cBSA) were determined. After oral administration of arctiin (30, 60, 120 mg/kgd) for three weeks, the levels of serum creatinine (Scr) and blood urea nitrogen (BUN) and 24-h urine protein content markedly decreased, while endogenous creatinine clearance rate (ECcr) significantly increased. The parameters of renal lesion, hypercellularity, infiltration of polymorphonuclear leukocyte (PMN), fibrinoid necrosis, focal and segmental proliferation and interstitial infiltration, were reversed. In addition, we observed that arctiin evidently reduced the levels of malondialdehyde (MDA) and pro-inflammatory cytokines including interleukin-6 (IL-6) and tumor necrosis factor (TNF-alpha), suppressed nuclear factor-kappaB p65 (NF-kappaB) DNA binding activity, and enhanced superoxide dismutase (SOD) activity. These findings suggest that the ameliorative effects of arctiin on glomerulonephritis is carried out mainly by suppression of NF-kappaB activation and nuclear translocation and the decreases in the levels of these pro-inflammatory cytokines, while SOD is involved in the inhibitory pathway of NF-kappaB activation. Arctiin has favorable potency for the development of an inhibitory agent of NF-kappaB and further application to clinical treatment of glomerulonephritis, though clinical studies are required.

Abstract
Evidence that small molecules extracted from traditional Chinese medicines (TCMs) have beneficial effects on health is increasingly being reported in the scientific literature and these compounds are now widely recognized as potential therapeutic drugs. There have been several detailed studies of the absorption, distribution, metabolism and excretion of these compounds in rats and humans. However, some active components have low bioavailability owing to their unsuitable physicochemical and biopharmaceutical characteristics, resulting in differences in vivo. The main problem in using natural products as a source of pharmaceutical lead compounds is the need to improve the bioavailability of these compounds. This review presents and discusses the current methods used for improvement and their impact on the bioavailability of some new pharmaceutical lead compounds from TCMs.

Abstract
Stress affects the gastrointestinal tract as part of the visceral response. Various stressors induce similar profiles of gut motor function alterations, including inhibition of gastric emptying, stimulation of colonic propulsive motility, and hypersensitivity to colorectal distension. In recent years, substantial progress has been made in our understanding of the underlying mechanisms of stress's impact on gut function. Activation of corticotropin-releasing factor (CRF) signaling pathways mediates both the inhibition of upper gastrointestinal (GI) and the stimulation of lower GI motor function through interaction with different CRF receptor subtypes. Here, we review how various stressors affect the gut, with special emphasis on the central and peripheral CRF signaling systems.

Abstract
AIM: To explore the effects of soothing the liver and regulating method on behavior and gastric tissue of stressed rats induced by constantly squeezing their tails.
METHODS: Thirty rats were randomly divided into control group, model group and Chaihu Shugansan group (n = 10). The animal model of stressed was established by constantly squeezing their tails for 4 wk. Mean while saline, Chaihu Shugansan decoction were administered respectively to three groups by gavage. The animal's general situation and amount of food and water intake were observed daily, body weight was measured weekly, and histopathologcal tests of stomach were performed four weeks later.
RESULTS: Rats in model group showed margination, pad batch, decline in excitement, activity and fight, getting sluggish, blunted in responsiveness, loose and withered hair. The above manifestations in Chaihu Shugansan decoction were not so marked compared with model group. The amount of food and water intake was less in model group than control group (the fourth wk: 22.0 ± 1.51 vs 25.70 ± 1.4, 10.33 ± 0.84 vs 11.29 ± 0.29, both P < 0.05), while the amount of food and water intake was more in Chaihu Shugansan group than model group (the fourth wk: 24.27 ± 2.3 vs 22.0 ± 1.51, 11.71 ± 1.26 vs10.33 ± 0.84, P < 0.05). Weight gain was significantly slower in model group than control group (P < 0.05), but weight gain was greater in Chaihu Shugansan group than model group, but no significance difference was observed.
CONCLUSION: The method of soothing the liver and regulating method not only alleviates depression, poor appetites and antagonized the weight loss, but also improves histology of stomach. It has certain both physical and mental effects against psychological stress.

Abstract
BACKGROUND Bone formation and resorption is a balanced and continuous process. When osteoclastic bone resorption exceeds osteoblastic bone formation, bone density decreases, which can lead to osteoporosis. Er-Zhi-Wan (EZW), a famous traditional Chinese formulation, has been developed as a restorative formula for hundreds of years, which contains two herbs viz. Herba Ecliptae and Fructus Ligustri Lucidi. EZW is widely used to prevent and treat various kidney diseases for its actions of nourishing the kidney yin and strengthening tendon and bone. The objective of current study was to investigate the effects of EZW on proliferation and differentiation of osteoblasts and osteoclasts in vitro using a serum pharmacological method. METHODS The rats were orally administered EZW (0.45, 1.8 and 7.2gkg(-1)) for total seven doses and twice a day, and then the different concentrations of EZW-containing serum were prepared. The proliferation of primary cultural osteoblasts, UMR106 and RAW264.7 cells and differentiation of osteoclasts were determined after these cells were treated with different concentrations of EZW-containing serum for a period of time. RESULTS The serum from rats treated with EZW for 4 days did not facilitate proliferation of primary cultural osteoblasts and UMR106 cells, but evidently inhibited both proliferation of RAW264.7 cells and differentiation of osteoclasts from RAW264.7 cells induced by receptor activator of nuclear factor kappaB ligand (RANK-L) and macrophage-colony stimulating factor (M-CSF). CONCLUSION Antiosteoporotic activity of EZW is carried out mainly via restraint of osteoclastic bone resorption, which is in accordance with the traditional Chinese medicine theory on nourishing the kidney yin. Therefore EZW has favorable potency to develop a new anti-osteoporotic agent in clinic.
