Discovery of Transfer Factors in Plant-Derived Proteins and an In Vitro Assessment of Their Immunological Activities.

Repeated exposure to pathogens leads to evolutionary selection of adaptive traits. Many species transfer immunological memory to their offspring to counteract future immune challenges. Transfer factors such as those found in the colostrum are among the many mechanisms where transfer of immunologic memory from one generation to the next can be achieved for an enhanced immune response. Here, a library of 100 plants with high protein contents was screened to find plant-based proteins that behave like a transfer factor moiety to boost human immunity. Aqueous extracts from candidate plants were tested in a human peripheral blood mononuclear cell (PBMC) cytotoxicity assay using human cancerous lymphoblast cells-with K562 cells as a target and natural killer cells as an effector. Plant extracts that caused PBMCs to exhibit enhanced killing beyond the capability of the colostrum-based transfer factor were considered hits. Primary screening yielded an 11% hit rate. The protein contents of these hits were tested via a Bradford assay and Coomassie-stained SDS-PAGE, where three extracts were confirmed to have high protein contents. Plants with high protein contents underwent C18 column fractionation using methanol gradients followed by membrane ultrafiltration to isolate protein fractions with molecular weights of <3 kDa, 3-30 kDa, and >30 kDa. It was found that the 3-30 kDa and >30 kDa fractions had high activity in the PBMC cytotoxicity assay. The 3-30 kDa ultrafiltrates from the top two hits, seeds from Raphanus sativus and Brassica juncea, were then selected for protein identification by mass spectrometry. The majority of the proteins in the fractions were found to be seed storage proteins, with a low abundance of proteins involved in plant defense and stress response. These findings suggest that Raphanus sativus or Brassica juncea extracts could be considered for further characterization and immune functional exploration with a possibility of supplemental use to bolster recipients' immune response.

UP360, a Standardized Composition from Extracts of Aloe barbadense, Poria cocos, and Rosemary officinalis Protected Against Sepsis and Mitigated Acute Lung Injury in Murine Models.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated and unbalanced immune response to microbial infection. Restoring immune homeostasis and infection control are considered the primary strategies to manage sepsis. Natural bioactives such as polysaccharide and polyphenols from botanicals are known for their immune modulation activity. In this study, we evaluated a standardized aloe-based composition, UP360 (constitute of polysaccharides from Aloe barbadense and Poria cocos and polyphenols from Rosemary officinalis) in lipopolysaccharide (LPS)-induced sepsis and acute inflammatory lung injury murine models. Prophylactic oral administration of UP360 for 7 days at an oral dose of 500 mg/kg improved the survival rate of mice by 62.5%, whereas all mice in the vehicle control group were deceased 82 h after LPS injection. The merit of combining these traditional herbs to yield the standardized composition UP360 was also demonstrated in this model with a mortality rate of only 30.8%, whereas 76.9%, 53.9%, and 61.5% were recorded for each individual constituents A. barbadense, P. cocos, and R. officinalis, respectively. Dose-correlated statistically significant reductions in proinflammatory cytokines and chemokine tumor necrosis factor alpha (TNF-α), interleukin (IL)-1ß, IL-6, and cytokine-induced neutrophil chemoattractant (CINC)-3 were observed for UP360 when administered at 250 and 500 mg/kg orally for 7 days before induction of acute lung injury (ALI) model in rats. The histopathology data from lung showed statistically significant 37.9% and 37% reductions in the overall lung damage severity and pulmonary edema, respectively, for UP360-treated rats. The aloe-based composition UP360 effectively improved the survival rate of septic animals and mitigated the severity of LPS-induced ALI in vivo. These data warrant further investigation of the composition for a potential application in human as an adjunct supplement in respiratory distress and sepsis.

Antinociceptive and Anti-Inflammatory Properties of Cannabidiol Alone and in Combination with Standardized Bioflavonoid Composition.

Symptom-alleviating therapies for osteoarthritis (OA) management are inadequate. Long-term application of first-line treatments, such as nonsteroidal anti-inflammatory drugs, is limited due to associated side effects. We believe that a combination of traditionally used botanical extracts, which have diverse active components that target multiple inflammatory pathways, may provide a safe and efficacious alternative to address the multifactorial nature of OA. Recently, cannabidiol (CBD), the major nonpsychoactive component of the hemp plant, has gained renewed global attention for its pharmacological actions. It has shown promise in reducing pain and inflammation in preclinical models of arthritis. In this study, widely employed inflammatory and noninflammatory animal pain models, such as the hot plate test, visceral pain model (writhing test), and carrageenan-induced rat paw edema model, were utilized to evaluate the antinociceptive and anti-inflammatory activity of CBD alone and in combination with standardized bioflavonoid compositions. CBD was tested at 5, 10, 20, and 40 mg/kg orally and at 5% topically. Administered alone, CBD produced dose-correlated, statistically significant pain inhibition in all the models. Enhanced performance in pain and inflammation reduction was observed when CBD was orally administered in complex with the bioflavonoid compositions. Data from this study show that for clinically meaningful efficacy against OA, CBD may have to be delivered in higher dosage or formulated with other medicinal plants with similar activities.

Efficacy of Acupuncture at the Sphenopalatine Ganglion in the Treatment of Persistent Allergic Rhinitis.

Objective: The aim of this research was to explore the hypothesis that acupuncture at the sphenopalatine ganglion (SPG), a new a new method of acupuncture, would be more efficacious and safe than traditional acupuncture in the treatment of persistent allergic rhinitis (PAR). Materials and Methods: For this study, 120 patients with PAR were randomly assigned to SPG acupuncture, traditional acupuncture (Yingxiang [LI 20], Hegu [LI 4], and Yintang [Ex-HN 3]), or drug treatment (budesonide nasal spray). Efficacy was assessed by using single symptoms, including sneezing, rhinorrhea, nasal obstruction and nasal itch, a total nasal symptoms score (TNSS), and a Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) before treatment, the day treatment ended, and 4-, 8-, 12-weeks later, respectively. Results: Four weeks after treatment ended, the effectiveness rate in the SPG-acupuncture group was superior to that of the traditional-acupuncture group (P = 0.033) but was still lower than that of the drug-treatment group (P = 0.039), with mean effectiveness rates of 69.70%, 44.44%, and 71.43%, respectively. However, these rates gradually decreased in each group during weeks 8 through 16. Moreover, statistically significant improvements in TNSS', and reductions in nasal congestion and sneezing symptoms were observed in the SPG-acupuncture group, compared with those in the traditional-acupuncture group as early as the day treatment ended and this continued throughout the observation period (P < 0.05). However, the improvement did not continue for sneezing, during weeks 8 through weeks 12 after treatment ended. The RQLQ of the SPG-acupuncture group was lower than that of the traditional-acupuncture group at week 12; however, there were no differences at weeks 8 and 16. Conclusions: The data generated by this study confirmed that acupuncture at the SPG alleviated the symptoms of PAR rapidly and safely, especially nasal obstruction, and improved the patients' life quality. These results were worthy of clinical promotion.

Morus alba, a Medicinal Plant for Appetite Suppression and Weight Loss.

The prevalence of obesity is expanding rapidly worldwide, making the disease a global burden with limited treatment options. The current obesity drug development trends suggest the possibility of reducing weight and reverse metabolic disturbances of obesity by controlling appetite. In this study, we screened more than 8000 plants from our plant library for the cannabinoid (CB1) receptor antagonists and identified Morus alba as a lead medicinal plant. Kuwanon G and Albanin G were isolated and identified from root-barks of Morus alba with 92% and 96% CB1 receptor ligand binding inhibitory activity, respectively. The bioflavonoid standardized extract was tested in the acute food intake study in rats at oral doses of 250 and 500 mg/kg for its appetite suppression activity. Diet-induced obesity in the C57BL/6J mice was used to evaluate the long-term food intake reduction activity and effect on the weight loss administered orally at 250 and 500 mg/kg for 7 weeks. Statistically significant and dose-dependent reduction in food intake was observed in both acute and long-term studies for the extract. Food intake reductions of 58.6% and 44.8% at 250 mg/kg and 50.1% and 44.3% at 500 mg/kg were observed at 1 and 2 h postfood provision, respectively. A 20% reduction in daily calorie intake was observed in the long-term study. Obese mice treated with the high dose of Morus root-bark extract showed 10.4 g (22.5%) and 7.1 g (16.5%) loss in body weight compared with the vehicle-treated obese animals (at week 7) and baseline, respectively. Statistically significant reductions in biochemical markers and visceral fat deposit were also observed. These results demonstrated that Morus alba extracts enriched in Kuwanon G, and Albanin G could be used alone to control appetite, manage body weight, and improve metabolic syndromes.

UP1306: A Composition Containing Standardized Extracts of Acacia catechu and Morus alba for Arthritis Management.

Osteoarthritis (OA) is characterized by progressive articular cartilage degradation. Although there have been significant advances in OA management, to date, there are no effective treatment options to modify progression of the disease. We believe these unmet needs could be bridged by nutrients from natural products. Collagen induced arthritis in rats was developed and utilized to evaluate anti-inflammatory and cartilage protection activity of orally administered botanical composition, UP1306 (50 mg/kg) and Methotrexate (75 µg/kg) daily for three weeks. Objective arthritis severity markers, urine, synovial lavage, and serum were collected. At necropsy, the hock joint from each rat was collected for histopathology analysis. Urinary cartilage degradation marker (CTX-II), pro-inflammatory cytokines (tumor necrosis factor α (TNF-α), interleukin-1ß (IL-1ß), and IL-6), and proteases (Matrix Metallopeptidase 3 (MMP3) and 13) were measured. Rats treated with UP1306 showed statistically significant improvements in arthritis severity markers, including uCTX-II (91.4% vs. collagen-induced arthritis (CIA)), serum IL-1ß, TNF-α, and IL-6 levels as well as synovial MMP-13. The histopathology data were also well aligned with the severity score of arthritis for both UP1306 and Methotrexate. UP1306, a botanical composition that contains a standardized blend of extracts from the heartwood of Acacia catechu and the root bark of Morus alba, could potentially be considered as a dietary supplement product for the management of arthritis.

Evaluation of Natural Product Compositions for Appetite Suppression.

A change in homeostasis between food intake and energy expenditure is the hallmark of obesity. Many plant-based weight-management products are available in dietary supplement markets with no direct efficacy comparison. In this in vivo acute feed intake study in rats, the appetite suppression efficacy of well-known natural ingredients in the weight-loss market were evaluated. We tested pure caffeine, potato skin extract, Cissus quadrangularis extract, Garcinia cambogia extract, Crocus sativus extract, raspberry ketone isolated from Rubus idaeus, one commercial product (Appetrex), and one novel composition (UP601). Rats treated with potato skin extract, Crocus sativus bulb extract, and Cissus quadrangularis extracts showed statistically significant reduction in food consumption only at the 2-hour timepoint with 44.9%, 34.1%, and 44.3% reductions, respectively, after food provision at an equivalent human dosage of 2 g, 10 g, and 10 g, respectively. Garcinia cambogia fruit extract and raspberry ketone from Rubus idaeus showed statistically significant reduction in food consumption only at the 1-hour timepoint with 33.7% and 79.4% reductions, respectively, after food provision at an equivalent human dosage of 8 g and 5 g, respectively. UP601 and Appetrex were compared at 230 mg/kg. While 88.5%, 73.8%, and 63.1% reductions in food intake were observed for the UP601 treatment group, 64.2%, 27.5%, and 34.7% reductions in food intake were observed for rats treated with Appetrex at 1 h, 2 h, and 4 h after food provision. The composition UP601 demonstrated superior activity in food intake compared to any of the dietary supplements marketed for appetite suppression tested in this study.

Therapeutic Potential of Salviae Miltiorrhizae Radix et Rhizoma against Human Diseases Based on Activation of Nrf2-Mediated Antioxidant Defense System: Bioactive Constituents and Mechanism of Action.

Oxidative stress plays a central role in the pathogenesis of many human diseases. The nuclear factor erythroid 2-related factor 2 (Nrf2) is a key transcription factor regulating the intracellular antioxidant response and is an emerging target for the prevention and therapy of oxidative stress-related diseases. Salviae Miltiorrhizae Radix et Rhizoma (SMRR) is a traditional Chinese medicine (TCM) and is commonly used for the therapy of cardiac cerebral diseases. Cumulative evidences indicated that the extract of SMRR and its constituents, represented by lipophilic diterpenoid quinones and hydrophilic phenolic acids, were capable of activating Nrf2 and inhibiting oxidative stress. These bioactive constituents demonstrated a therapeutic potential against human diseases, exemplified by cardiovascular diseases, neurodegenerative diseases, diabetes, nephropathy, and inflammation, based on the induction of Nrf2-mediated antioxidant response and the inhibition of oxidative stress. In the present review, we introduced the SMRR and Nrf2 signaling pathway, summarized the constituents with an Nrf2-inducing effect isolated from SMRR, and discussed the molecular mechanism and pharmacological functions of the SMRR extract and its constituents.

Repeated dose 28-day oral toxicity study of a botanical composition composed of Morus alba and Acacia catechu in rats.

Patients with osteoarthritis experience debilitating pain and loss of joint function that requires chronic treatment. While nonsteroidal anti-inflammatory drugs (NSAIDs) have been effective for temporary symptomatic relief, their long term usage has been limited by their associated side-effects. UP1306, a standardized novel composition from the extracts of root barks of Morus alba and the heartwoods of Acacia catechu, has been used in over the counter joint care dietary supplements as a safer alternative. These two medicinal plants have long track records of safe human consumption. Here we evaluated the potential adverse effects of orally administered UP1306 in Sprague Dawley rats following a 28-day repeated oral dose toxicity study. UP1306 at doses of 500, 1000 and 2000 mg/kg/day were administered orally to rats for 4 weeks. A 2-week recovery group from the high dose (2000 mg/kg) and vehicle treated groups were included. No morbidity or mortality was observed for the duration of the study. No significant differences between groups in body weights, food consumption, hematology, clinical chemistry, organ weights, gross pathology and histopathology were documented. Minor aberrations from the normal observed for the main groups were considered reversible as they were not evident in the recovery period. In conclusion, the no-observed-adverse-effect-level (NOAEL) of UP1306 was considered to be the highest dose tested, 2000 mg/kg/day, both for male and female rats.

Cartilage Protection and Analgesic Activity of a Botanical Composition Comprised of Morus alba, Scutellaria baicalensis, and Acacia catechu.

Although there have been augmented advances in drug discovery, current OA management is inadequate due to the lack of successful therapies proven to be effective in modifying disease progression. For some, the risk outweighs the benefit. As a result, there is a desperate need for safe and efficacious natural alternatives. Here we evaluated a composition from Morus alba, Scutellaria baicalensis, and Acacia catechu in maintaining joint structural integrity and alleviating OA associated symptoms in monoiodoacetate- (MIA-) induced rat OA disease model. Study lasted for 6 weeks. 59.6%, 64.6%, 70.7%, 69.9%, and 70.3% reductions in pain sensitivity were observed for rats treated with the composition from week 1 to week 5, respectively. Statistically significant improvements in articular cartilage matrix integrity (maintained at 57.1% versus MIA + vehicle treated rats) were shown from the modified total Mankin score for animals treated with the composition. The composition showed a statistically significant reduction in uCTX-II level (54.1% reductions). The merit of combining these botanicals was also demonstrated in their synergistic analgesic activity. Therefore, the standardized blend of Morus alba, Scutellaria baicalensis, and Acacia catechu could potentially be considered as an alternative remedy from natural sources for the management of OA and/or its associated symptoms.

A Botanical Composition from Morus alba, Ilex paraguariensis, and Rosmarinus officinalis for Body Weight Management.

Obesity is the largest and fastest growing public health catastrophe in the world affecting both adults and children with a prevalence impacting more than one-third of United States (US) adult population. Although the long-term solution lies in lifestyle changes in the form of dieting and exercise, intervention is required for those who are already obese. Unfortunately, treatment options remain quite limited due to associated side effects of conventional therapeutics. As a natural alternative, in this study we describe the beneficial effect of a standardized composition (UP603) comprised of extracts from Morus alba, Ilex paraguariensis, and Rosmarinus officinalis in improving metabolic disorders in high fat diet (HFD) and high fat & high fructose diet (HFFD) induced obese C57BL/6J mice. Mice treated with UP603 showed dose-correlated decrease in body weight gains compared to vehicle treated HFFD group. Following 7 weeks of treatment, the changes in body weight gains from baseline were found as 6.4%, 27.3%, 2.0%, 3.1%, 0.4%, and -2.9% for normal control diet, HFFD, Orlistat, 450, 650, and 850 mg/kg UP603 treated animals, respectively. Reductions of 7.9-21.1% in total cholesterol, 25.4-44.6% in triglyceride, and 22.5-38.2% in low-density lipoprotein were observed for mice treated with 450-850 mg/kg of UP603. In a dual energy X-ray absorptiometry scan, percentage body fat of 18.9%, 47.8%, 46.1%, and 40.4% were found for mice treated with normal control, HFD, Orlistat, and UP603, respectively. Reductions of 65.5% and 16.4% in insulin and leptin, respectively, and 2.1-fold increase in ghrelin level were also observed for the UP603 group. Statistically significant improvements in nonalcoholic steatohepatitis scores were also observed from liver histology for mice treated with UP603. Hence, UP603, a standardized botanical composition from M. alba, I. paraguariensis, and R. officinalis could potentially be considered as a natural alternative to maintain healthy body weight and to manage metabolic syndrome.

A Botanical Composition Mitigates Cartilage Degradations and Pain Sensitivity in Osteoarthritis Disease Model.

Osteoarthritis (OA) is a degenerative joint disease characterized by a progressive articular cartilage degradation manifested with significant functional impairment in consort with signs and symptoms of inflammation, stiffness, and loss of mobility. Current OA management is inadequate due to the lack of nominal therapies proven to be effective in hampering disease progression where symptomatic therapy focused intervention masks the primary etiology leading to irreversible structural damage. In this study, we describe the effect of UP1306, a composition containing a proprietary blend of two standardized extracts from the heartwood of Acacia catechu and the root bark of Morus alba, in maintaining joint structural integrity and alleviating OA associated symptoms in monosodium-iodoacetate (MIA)-induced rat OA disease model. Data from pain sensitivity, histopathology, and glycosaminoglycan (GAG) level were analyzed. Diclofenac at 10 mg/kg was used as a reference compound. Ex vivo proteoglycan protection model demonstrated 31.5%, 50.0%, and 54.8% inhibitions of proteoglycan degradations from UP1306 at concentrations of 50, 100, and 200 µg/mL, respectively. The merit of combining two bioflavonoid standardized extracts from A. catechu and M. alba was demonstrated in their Ex vivo synergistic proteoglycan protection activity. In the MIA in vivo OA model, administered orally at 500 mg/kg, UP1306 resulted in reductions of 17.5%, 29.0%, 34.4%, 33.5%, and 40.9% through week 1-5 in pain sensitivity, statistically significant improvements in articular cartilage matrix integrity, and minimal subchondral bone damage. Therefore, UP1306 could potentially be considered as an alternative remedy from natural sources for the management of OA and/or its associated symptoms.

UP601, a standardized botanical composition composed of Morus alba, Yerba mate and Magnolia officinalis for weight loss.

BACKGROUND: The prevalence of obesity is surging in an alarming rate all over the world. Pharmaceutical drugs are considered potential adjunctive therapy to lifestyle modification. However, for most, besides being too expensive, their long term usages are hindered by their severe adverse effects. Here we describe the effect of UP601, a standardized blend of extracts from Morus alba, Yerba mate and Magnolia officinalis, in modulating a number of obesity-related phenotypic and biochemical markers in a high-fat high-fructose (HFF)-induced C57BL/6J mouse model of obesity. METHOD: Adipogenesis activity of the composition was assessed in 3T3-L1 cells in vitro. Effects of UP601 on body weight and metabolic markers were evaluated. It was administered at oral doses of 300 mg/kg, 450 mg/kg and 600 mg/kg for 7 weeks. Orlistat (40 mg/kg/day) was used as a positive control. Body compositions of mice were assessed using dual energy X-ray absorptiometry (DEXA). Serum biomarkers were measured for liver function and lipid profiling. Relative organ weights were determined. Histopathological analysis was performed for non-alcoholic steatohepatitis (NASH) scoring. RESULTS: UP601 at 250 µg/ml resulted in 1.8-fold increase in lipolysis. Statistically significant changes in body weight (decreased by 9.1, 19.6 and 25.6% compared to the HFF group at week-7) were observed for mice treated with UP601 at 300, 450 and 600 mg/kg, respectively. Reductions of 9.1, 16.9, and 18.6% in total cholesterol; 45.0, 55.0, 63.6% in triglyceride; 34.8, 37.1 and 41.6% in LDL; 3.2, 21.6 (P = 0.03) and 33.7% (P = 0.005) in serum glucose were observed for UP601 at 300, 450 and 600 mg/kg, respectively. Body fat distribution was found reduced by 31.6 and 17.2% for the 450 mg/kg UP601 and orlistat, respectively, from the DEXA scan analysis. Up to an 89.1% reduction in mesenteric fat deposit was observed for UP601 in relative organ weight. Statistically significant improvements in NASH scores were observed for mice treated with UP601. CONCLUSION: UP601, a standardized botanical composition from Morus alba, Yerba mate and Magnolia officinalis could potentially be used for achieving healthy weight loss and maintenance.

[Effects of Acupuncture at "Shenmen" (HT 7) on Brainwaves and Cognitive Ability in Rats with Sleep Deprivation].

OBJECTIVE: To observe the effects of acupuncture at "Shenmen" (HT 7) on brainwaves and cognitive ability in rats with sleep deprivation. METHODS: SD rats were randomly divided into control group, model group, acupuncture group and sham acupuncture group, 15 rats in each group. Insomnia model rats were established by sleep deprivation for 72 hours. Acupuncture was applied to acupuncture group at bilateral "Shenmen" (HT 7) for 20 min, once daily for 7 days. Rats in the sham acupuncture group received superficial insertion of 1 mm and without retaining needle. The learning and memory abilities of rats were eva-luated by Hexagonal maze. The BL-420 F physiological recorder was used to record EEG for 30 min on the 1st, 4th, 7th and 10th day respectively, and the frequency of each wave was analyzed. RESULTS: After sleep deprivation, the frequency of searching the exits of Hexagonal maze in the model group was obviously increased, the searching time was shortened, the number of searching errors was increased obviously, and the cognitive rate was decreased (P<0.01). Compared with the model group and the sham acupuncture group, the frequency of searching the exits in the acupuncture group was obviously decreased, the searching time was longer, the number of seeking errors was decreased, and the cognitive rate was increased (P<0.05). Compared with the control group, the EEG of δ wave in the model group was decreased while ß wave increased with statistical significance (P<0.01). Compared with the model group, the δ wave of rats in the acupuncture group was significantly increased and the ß wave was significantly decreased (P<0.05). There were no statistically significant differences between the sham acupuncture group and the model group (P>0.05). CONCLUSIONS: Acupuncture at HT 7 can effectively improve the cognitive abilities and brainwaves in sleep deprived rats.

Appetite Suppression and Antiobesity Effect of a Botanical Composition Composed of Morus alba, Yerba mate, and Magnolia officinalis.

Background. Obesity and its comorbidities continue to challenge the world at an alarming rate. Although the long term solution lies on lifestyle changes in the form of dieting and exercising, drug, medical food, or dietary supplement interventions are required for those who are already obese. Here we describe a standardized blend composed of extracts from three medicinal plants: Morus alba, Yerba mate, and Magnolia officinalis for appetite suppression and metabolic disorders management. Method. Extracts were standardized to yield a composition designated as UP601. Appetite suppression activity was tested in acute feed intake rat model. Efficacy was evaluated in C57BL/6J mouse models treated with oral doses of 1.3 g/kg/day for 7 weeks. Orlistat at 40 mg/kg/day was used as a positive control. Body compositions of mice were assessed using a dual energy X-ray absorptiometry (DEXA). ELISA was done for insulin, leptin, and ghrelin level quantitation. Nonalcoholic steatohepatitis (NASH) scoring was conducted. Results. Marked acute hypophagia with 81.8, 75.3, 43.9, and 30.9% reductions in food intake at 2, 4, 6, and 24 hours were observed for UP601. Decreases in body weight gain (21.5% compared to the HFD at weeks 7 and 8.2% compared to baseline) and calorie intake (40.5% for the first week) were observed. 75.9% and 46.8% reductions in insulin and leptin, respectively, 4.2-fold increase in ghrelin level, and reductions of 18.6% in cholesterol and 59% in low-density lipoprotein were documented. A percentage body fat of 18.9%, 47.8%, 46.1%, and 30.4% was found for mice treated with normal control, HFD, Orlistat, and UP601, respectively. 59.3% less mesenteric fat pad and improved NASH scores were observed for UP601. Conclusion. UP601, a standardized botanical composition from Morus alba, Yerba mate, and Magnolia officinalis could be used as a natural alternative for appetite suppression, maintaining healthy body weight and metabolism management.

Hepatoprotective Activity of an Herbal Composition, MAP, a Standardized Blend Comprising Myristica fragrans, Astragalus membranaceus, and Poria cocos.

Historically, botanicals have been reported to possess good antioxidative activities as demonstrated by their free radical scavenging property rendering their usage in liver protection. In this study, we describe the potential use of MAP, a standardized blend comprising three extracts from Myristica fragrans, Astragalus membranaceus, and Poria cocos, in ameliorating chemically induced acute liver toxicities. Acetaminophen (APAP) and carbon tetrachloride (CCl4)-induced acute liver toxicity models in mice were utilized. Hepatic functional tests from serum collected at T24, histopathology analysis, and merit of blending three standardized extracts were evaluated. MAP administered at doses of 150-400 mg/kg showed statistically significant and dose-correlated inhibitions of serum alanine aminotransferase (ALT) ranging from 30.8% (P ≤ .05) to 88.1% (P = .0001) in the APAP and 66.9% (P = .002) to 83.7% (P = .0002) in the CCl4 models, respectively. Moreover, MAP resulted in up to 75.7%, 60.9%, and 33.3% reductions in serum aspartate aminotransferase (AST), bile acid, and total bilirubin, respectively. Mice treated with oral doses of composition of MAP at 300 mg/kg showed statistically significant reduction in hepatocyte necrosis when compared with vehicle control. Unexpected synergistic protection of liver damage was also observed. Therefore, the composition, MAP, could be potentially utilized as an effective hepatic detoxifying agent for the protection of liver damage.

A Standardized Composition from Extracts of Myristica Fragrans, Astragalus Membranaceus, and Poria Cocos Protects Liver from Acute Ethanol Insult.

Despite the promising advances in therapeutic discovery, there still is a major challenge in the development of a safe, effective, and economical intervention for managing alcohol-related liver disorders. In this study, we describe the potential use of "MAP," a standardized composition comprising three extracts from Myristica fragrans, Astragalus membranaceus, and Poria cocos, in ameliorating alcohol-induced acute liver toxicity. Ethanol-induced acute hepatotoxicity as an animal model of binge drinking was utilized. Mice received oral doses of MAP at 300 mg/kg for four consecutive days. Mice were orally gavaged with 50% ethanol in 12 mL/kg dosing volume following the third dose of MAP every 12 h thereafter for a total of three doses. Hepatic functional tests from serum collected at T12, and hepatic glutathione (GSH), superoxide dismutases (SODs), and triglyceride from liver homogenates were evaluated. Histopathology analysis and alcoholic steatohepatitis (ASH) scoring were also determined. Excessive increases of serum alanine aminotransferase and aspartate aminotransferase were significantly inhibited at 46.3% and 43.6%, respectively, when mice were treated with MAP. MAP replenished the depleted SOD by more than 60%, while causing significant stimulation of GSH productions. MAP showed statistically significant reduction in ballooning degeneration, vascular steatosis, cytoplasmic or nuclear condensation, and shrinkage, as well as inflammations when compared to vehicle-treated alcohol-induced liver toxicity model. Mice treated with MAP showed statistically significant reduction in ASH scoring when compared to vehicle control. Therefore, the composition MAP could be potentially utilized as an effective hepatic-detoxifying agent for the protection of liver damage caused by alcohol consumptions.

Hepatoprotective Activity of Herbal Composition SAL, a Standardize Blend Comprised of Schisandra chinensis, Artemisia capillaris, and Aloe barbadensis.

Some botanicals have been reported to possess antioxidative activities acting as scavengers of free radicals rendering their usage in herbal medicine. Here we describe the potential use of "SAL," a standardized blend comprised of three extracts from Schisandra chinensis, Artemisia capillaris, and Aloe barbadensis, in mitigating chemically induced acute liver toxicities. Acetaminophen and carbon tetrachloride induced acute liver toxicity models in mice were utilized. Hepatic functional tests from serum collected at T24 and hepatic glutathione and superoxide dismutases from liver homogenates were evaluated. Histopathology analysis and merit of blending 3 standardized extracts were also confirmed. Statistically significant and dose-correlated inhibitions in serum ALT ranging from 52.5% (p = 0.004) to 34.6% (p = 0.05) in the APAP and 46.3% (p < 0.001) to 29.9% (p = 0.02) in the CCl4 models were observed for SAL administered at doses of 400-250 mg/kg. Moreover, SAL resulted in up to 60.6% and 80.2% reductions in serums AST and bile acid, respectively. The composition replenished depleted hepatic glutathione in association with an increase of hepatic superoxide dismutase. Unexpected synergistic protection from liver damage was also observed. Therefore, the composition SAL could be potentially utilized as an effective hepatic-detoxification agent for the protection from liver damage.

Analgesic and anti-inflammatory effects of UP1304, a botanical composite containing standardized extracts of Curcuma longa and Morus alba.

OBJECTIVE: Though the initial etiologies of arthritis are multifactorial, clinically, patients share the prime complaints of the disease, pain. Here the authors assessed the analgesic and anti-inflammatory effects of UP1304, a composite that contains a standardized blend of extracts from the rhizome of Curcuma longa and the root bark of Morus alba, on rats with carrageenan-induced paw edema. METHODS: A plant library was screened for bradykinin receptor antagonists. In vivo, the anti-inflammatory and analgesic effects of the standardized composite, UP1304, were evaluated in rats with carrageenan-induced paw edema using oral dose ranges of 100-400 mg/kg. Ibuprofen, at a dose of 200 mg/kg, was used as a reference compound. In vitro, cyclooxygenase (COX) and lipoxygenase (LOX) inhibition assays were performed to evaluate the degree of inflammation. RESULTS: Statistically significant improvements in pain resistance and paw edema suppression were observed in animals treated with UP1304, when compared to vehicle-treated rats. Results from the highest dose of UP1304 (400 mg/kg) were similar to those achieved by ibuprofen treatment at 200 mg/kg. In vitro, UP1304 showed dose-dependent inhibition of the enzymatic activities of COX and LOX. A half-maximal inhibitory concentration of 9.6 µg/mL for bradykinin B1 inhibition was calculated for the organic extract of C. longa. Curcumin showed Ki values of 2.73 and 58 µg/mL for bradykinin receptors B1 and B2, respectively. CONCLUSION: Data presented here suggest that UP1304, analgesic and anti-inflammatory agent of botanical origin, acted as a bradykinin receptor B1 and B2 antagonist, and inhibited COX and LOX enzyme activities. This compound should be considered for the management of symptoms associated with arthritis.

[Temporal and Spatial Distribution of Phosphorus in Paddy Fields Under Cyclic Irrigation of Drainage Water].

Considering the potential of cyclic irrigation to increase rainfall use efficiency and reduce agricultural non-point pollution, the experiment of phosphorus transport in paddy fields under cyclic irrigation of drainage water was conducted to address the problem of phosphorus loss pollution and the mismatch between rainfall temporal distribution and crop requirement in the south of China. Lotus pond water and fishpond water were used to irrigate paddy fields for monitoring concentrations of total phosphorus (TP), dissolved phosphorus (DP), and dissolved reactive phosphorus (DRP) in surface water and leachate, and soil profile total phosphorus and Olsen-P concentrations. The results showed that the concentrations of TP, DP and DRP in surface water and leachate decreased along the field under cyclic irrigation of drainage water, especially the phosphorus concentrations of leachate dropped more obviously. As the phosphorus content of cyclic irrigation water sources varied within a certain range, phosphorus concentrations of surface water and leachate did not increased. The concentrations of TP, DP and DRP in surface water and leachate varied with cyclic irrigation time, and the least phosphorus concentrations were observed in August. Top soil Olsen-P concentration decreased along the field and increased with phosphorus content of cyclic irrigation water sources, and soil profile TP concentration was not influenced by cyclic irrigation. Phosphorus removal ratio of paddy field could be increased by extending field length or cyclic irrigation in August.
