The Effects of Acupuncture Stimulation for Brain Activation and Alcohol Abstinence Self-Efficacy: Functional MRI Study.

We attempted to investigate whether acupuncture stimulation at HT7 can have an effect on brain activation patterns and alcohol abstinence self-efficacy. Thirty-four right-handed healthy subjects were recruited for this study. They were randomly assigned into two groups: the HT7 (Shenmen) group and the LI5 (Yangxi) group. Acupuncture stimulation was performed using a block paradigm during fMRI scanning. Additionally, the Korean version of Alcohol Abstinence Self-Efficacy Scale (AASES) was used to determine the effect of acupuncture stimulation on self-efficacy to abstain from alcohol use. According to the result of fMRI group analysis, the activation induced by HT7 stimulation was found on the bilateral postcentral gyrus, inferior parietal lobule, inferior frontal gyrus, claustrum, insula, and anterior lobe of the cerebellum, as well as on the left posterior lobe of the cerebellum (p < 0.001, uncorrected). According to the AASES analysis, the interaction effect for gender and treatment was marginally significant (F(1, 30) = 4.152, p = 0.050). For female group, the simple main effect of treatment was significant (F(1, 11) = 8.040, p = 0.016), indicating that the mean change score was higher in the HT7 stimulation than in the LI5 stimulation. Therefore, our study has provided evidence to support that HT7 stimulation has a positive therapeutic effect on the alcohol-related diseases.

Effect of dietary supplementation with Suaeda maritima on blood physiology, innate immune response, and disease resistance in olive flounder against Miamiensis avidus.

The effect of Suaeda maritima enriched diet on blood physiology, innate immune response, and disease resistance in olive flounder Paralichythys olivaceus against Miamiensis avidus on weeks 1, 2, and 4 was investigated. Feeding with any enriched diet and then challenging with M. avidus significantly increased white blood cells (WBC) on weeks 2 and 4; the red blood cells (RBC) significantly increased with 0.1% and 1.0% enriched diets on week 4. The hemoglobin (Hb) and hematocrit (Ht) levels significantly increased when fed with 0.1% and 1.0% supplementation diets on weeks 2 and 4. The mean corpuscular volume (MCV) did not significantly vary with any diet and time; however the mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) significantly increased with 0.1% and 1.0% supplementation diets on weeks 2 and 4. The leukocytes such as lymphocytes (Lym), monocytes (Mon), neutrophils (Neu) and biochemical parameters such as total protein (TP), glucose (GLU), and calcium (CAL) levels significantly increased in 0.1% and 1.0% supplementation diet fed groups on weeks 2 and 4. The serum lysozyme activity was significantly enhanced in 0.1% and 1.0% supplementation diet fed groups from weeks 1 to 4 when compared to the control (0% herbal extract enriched diet). The scuticocidal activity and respiratory burst activity were significantly enhanced when fish were fed with 0.1% and 1.0% supplementation diets from weeks 2 and 4. The protective effect in terms of cumulative mortality (50% and 40%) was low in groups on being fed with 0.1% and 1.0% supplemented diet. Therefore the present study suggested that 0.1% and 1.0% S. maritime-supplemented diets protect the hematological and biochemical parameters, improving the innate immunity, affording protection disease from M. avidus infection in olive flounder.

Pomegranate enriched diet enhances the hematology, innate immune response, and disease resistance in olive flounder against Philasterides dicentrarchi.

Olive flounder, Paralichythys olivaceus fed with pomegranate enriched diet and challenged with or without Philasterides dicentrarchi had a significantly higher white blood cell (WBC) count on weeks 2 and 4 than the infected group fed with non enriched diet (standard diet). Similarly the red blood cell (RBC) counts did not significantly change in control and treated fish on weeks 1 and 2. It was significantly increased in treated fish on week 2 when compared to the control. In both the groups the hemoglobin (Hb) and hematocrit (Ht) levels significantly increased on weeks 2 and 4. The mean corpuscular volume (MCV) did not significantly change at any time in both groups whereas mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) increased significantly on week 4 in the treated group. The leukocytes such as lymphocytes (Lym), monocytes (Mon), neutrophils (Neu), and biochemical parameters such as total protein (TP), glucose (GLU), and calcium (CAL) levels significantly increased in treated groups on week 2 or 4 as compared to the control. The scuticocidal activity and respiratory burst activity were significantly enhanced in treated groups with or without parasite on weeks 2-4. However, the serum lysozyme activity was significantly enhanced from weeks 1 to 4. The protective response in terms of cumulative mortality was low in groups fed with enriched diet against parasite when compared to control. Therefore, we suggest that pomegranate enriched diet following challenge with P. dicentrarchi restores the altered hematological and biochemical parameters, and improves the innate immune system in olive flounder against P. dicentrarchi.

Effect of Coriolus versicolor supplemented diet on innate immune response and disease resistance in kelp grouper Epinephelus bruneus against Listonella anguillarum.

The effect of Coriolus versicolor extract supplemented diets on innate immune response and disease resistance in kelp grouper, Epinephelus bruneus against Listonella anguillarum, is reported. Kelp grouper were divided into four groups of 25 each and fed with C. versicolor enriched diets at 0% (control), 0.01%, 0.1%, and 1.0% level. After 30 days of feeding, all fish were injected interaperitoneally (i.p.) with 50 µl of L. anguillarum (4.7 × 10(7) CFU) to investigate the immune parameters at weeks 1, 2, and 4. The reactive oxygen species and reactive nitrogen species production were significantly enhanced in fish fed with 0.1% and 1.0% supplementation diets from weeks 1-4 when compared to the non enriched diet fed and infected control. The phagocytic activity significantly increased with 0.1% and 1.0% diets on weeks 2 and 4. The leucocyte myeloperoxidase content, lysozyme activity, and total protein level significantly increased when fed with 0.1% and 1.0% supplementation diets from weeks 1-4. The cumulative mortality was 35% and 45% in 1.0% and 0.1% enriched diet fed groups whereas it was 55% and 80% in 0.01% and 0% groups respectively. The present results suggest that diets enriched with C. versicolor at 0.1% or 1.0% level positively enhance the innate immune system and affords protection from L. anguillarum.

Enhancement of Eriobotrya japonica extracts on non-specific immune response and disease resistance in kelp grouper Epinephelus bruneus against Vibrio carchariae.

The present study investigated the effect of Eriobotrya japonica extracts at 0%, 0.1%, 1.0%, and 2.0% doses supplementation with feed on non-specific immune response, hematological and biochemical profile, and disease resistance against Vibrio carchariae in kelp grouper Epinephelus bruneus at weeks 1, 2, and 4. The white blood cell (WBC) significantly increased in fish fed with 0.1%, 1.0%, and 2.0% diets on weeks 1 and 2 when compared to the control. However, the glucose always decreased from the control except on week 2 against pathogen. The serum total protein, albumin, and globulin significantly increased at week 2 but they did not changed significantly at weeks 1 and 4. The superoxide anion, lymphokines production index, and phogocytosis did not significantly increased in any diet on the first week whereas it was significantly enhanced in 1.0% and 2.0% supplementation diets on weeks 2 and 4 against V. carchariae when compared to control. All diets significantly enhanced the serum lysozyme activity, bactericidal activity, and haemolytic complement activity from weeks 1-4 as compared to control. The serum agglutinating antibody titre did not significantly enhance on the first week whereas it was significantly enhanced on weeks 2 and 4. Fish fed with 1.0% and 2.0% doses diets was found lower mortality than 0.1% diet. Thus, this study suggested that 1.0% and 2.0% doses supplementation diets could be advocated to enhance the immune response and production disease from V. carchariae in E. bruneus.

Molecular characterization and tissue distribution of ferritin M in kelp grouper, Epinephelus bruneus.

This study, reports the identification and analysis of ferritin M chain, from kelp grouper, Epinephelus bruneus (EbFerM); it comprises 1004 base pair (bp), including 528bp open reading frame (ORF) which encodes 176 amino acid (aa) residues; the calculated molecular weight is 20kDa. The 5'-untranslated region (UTR) possesses 476bp proceeded by a putative Iron Regulatory Element (IRE). Pair wise alignments showed that EbFerM shared 94% identity with that of Larimichthys crocea and Sciaenops. It is expressed in abundance in liver, spleen, and kidney when challenged with Vibrio anguillarum, lipopolysaccharide (LPS), or poly I:C.

Styrax japonica supplementation diet enhances the innate immune response in Epinephelus bruneus against bacterial and protozoan infections.

Kelp grouper, Epinephelus bruneus, fed for 30 days with 0% (control), 0.1%, 1.0%, and 2.0% of Styrax japonica supplementation diets, led to reductions in mortality after being challenged with a bacterium (Vibrio harveyi) and a ciliate protozoan (Uronema marinum). The enriched diets significantly increased the survival rate as compared to the controls. The phagocytic and respiratory activities were significantly increased in kelp groupers given 1.0% and 2.0% enriched diets. The complement activity, lysozyme activity, serum bactericidal activity, and total protein level significantly increased with any enriched diet against the pathogens; however antiprotease activity and myeloperoxidase levels significantly increased only with 1.0% and 2.0% enriched diets while the α2-macroglobulin level was significantly enhanced with 1.0% enriched diet. The study suggests that incorporation of S. japonica at 1.0% and 2.0% level in the diet significantly enhances the immune responses in the kelp grouper E. bruneus against V. harveyi and U. marinum.

Kalopanax pictus as feed additive controls bacterial and parasitic infections in kelp grouper, Epinephelus bruneus.

Feeding kelp grouper, Epinephelus bruneus (26.1 ± 1.4), with 0%, 0.1%, 1.0%, and 2.0% Kalopanax pictus extract-supplementation diets, for 30 days reduced mortality on being challenged intraperitoneally 100 µl with bacterium Vibrio alginolyticus (2.1 × 10(7) cfu ml(-1)) and ciliate parasite Philasterides dicentrarchi (2.3 × 10(7) ciliates ml(-1)). The red blood cells (RBC), white blood cells (WBC), haemoglobin, haematocrit, lymphocytes, and monocytes levels significantly increased in kelp grouper fed with all doses of K. pictus-supplementation diets and challenged with bacterium and parasite when compared to control. However, the levels of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), neutrophils, and thrombocytes did not significantly. The phagocytic activity, complement activity, and antiprotease activity did not significantly change in kelp grouper fed with 0.1% K. pictus-supplementation diets and challenged with bacterium and parasite. The respiratory activity, lysozyme activity, bactericidal activity, total protein level, and myeloperoxidase levels significantly increased in kelp grouper fed with all the doses of K. pictus-supplementation diet and challenged with bacterium and parasite. However, α2-macroglobulin level significantly increased with 1.0% diet, but not with 0.1% and 2.0% diets. Therefore this study suggests that 1.0% and 2.0% K. pictus-supplementation diets positively protected and enhanced the immune system in kelp grouper E. bruneus against V. alginolyticus and P. dicentrarchi infection.

Probiotics and herbal mixtures enhance the growth, blood constituents, and nonspecific immune response in Paralichthys olivaceus against Streptococcus parauberis.

The present study was reported the effect of probiotics and herbals mixture supplementation diet on growth, blood constituents, and nonspecific immune response in olive flounder Paralichthys olivaceus against Streptococcus parauberis on weeks 1, 2, 4, 6, 8, 10, and 12 after injected intraperitoneally (i.p.) with 50 µl of PBS (phosphate buffer saline) containing S. parauberis (2.1 × 107 CFU ml⁻¹). The initial weight did not significantly increased in supplementation diet group from 1 to 4 weeks, whereas it was significantly increased from weeks 6 to 12 as compared to fish fed without supplementation diet. The serum aspartate aminotransferase (SGOT) and alanine aminotransferase (SGPT) activities significantly increased from weeks 4 to 12 in infected fish fed with supplementation diet compared to fish fed without supplementation diet. However, the total protein (TP) and glucose (GLU) levels were significantly increased in infected fish fed with supplementation diet after 6 weeks. The phagocytic, respiratory burst, complement, and lysozyme activities significantly enhanced in infected fish fed with supplementation diet from weeks 4 to 12 as compared to fish fed without supplementation diet. These results suggested that different probiotics and herbals mixture supplementation diet enhanced the growth, blood biochemical constituents, and nonspecific immunity in olive flounder against S. parauberis.

Protective effect of herbal and probiotics enriched diet on haematological and immunity status of Oplegnathus fasciatus (Temminck & Schlegel) against Edwardsiella tarda.

This study determines the effect of diet enriched with the herb Baical skullcap Scutellaria baicalensis, and/or probiotics Lactobacillus sakei BK19 in rock bream, Oplegnathus fasciatus (32 ± 3 g) against Edwardsiella tarda. The changes in haematological parameters, innate immune response, and disease resistance were investigated after 1, 3, and 6 weeks. The white blood cell count (WBC: 10(4) mm(-3)), red blood cell count (RBC: 10(6) mm(-3)), and haemoglobin (Hb: g dl(-1)) levels significant increased (P < 0.05) with mixed diet on 3rd and 6th week and probiotics enriched diet on 6th week. The haematocrit (Ht: %) level significantly increased (P < 0.05) when fed with mixed diet on weeks 1-6. Interestingly, in mixed diet group the lymphocytes (LYM), monocytes (MON), and neutrophils (NEU) significantly increased from week 1-6. The eosinophils (EOS) significantly increased in all the treated groups. In the probiotics or mixed diet groups the total protein (TP: g dl(-1)) increased significantly on weeks 3 and 6. The serum lysozyme activity significantly was enhanced in all the treated groups indicating an increase in the innate immunity level. Serum complement, antiprotease activities, reactive oxygen species (ROS) and reactive nitrogen species (RNS) production significantly increased from week 1-6 with mixed diet. The maximum protection against E. tarda was recorded in mixed diet group with a minimum cumulative mortality of 20% and a high relative percent survival (RPS) of 72.84. In the probiotics and herbal diet groups the cumulative mortality was 25% and 35% and RPS was 68.63 and 59.42, respectively. This study indicates that administration of probiotics or mixed diets can effectively minimize the mortality and restore the altered hematological parameters and enhancing the innate immunity in O. fasciatus against E. tarda.

Effect of Punica granatum solvent extracts on immune system and disease resistance in Paralichthys olivaceus against lymphocystis disease virus (LDV).

We report the effect of aqueous, ethanol, and methanol solvent leaf extracts of Punica granatum on innate immune mechanisms, such as phagocytosis activity, respiratory burst activity, alternative complement activity, lysozyme activity and functional immunity in terms of percentage cumulative mortality and Relative Percent Survival (RPS) in olive flounder Paralichthys olivaceus naturally infected with lymphocystis disease virus (LDV) after 8 weeks. Infected fish were intraperitoneally administered with 0, 5, 50, and 100 mg kg(-1) body weight of solvent extracts. In groups treated with 50 and 100 mg kg(-1) body weight, the chosen innate immune parameters significantly increased after 8 weeks when compared to 0 mg kg(-1) dose, but not with 5 mg kg(-1). Administration of P. granatum solvent extracts for 8 weeks significantly reduced the percentage mortality with the consequent increase in RPS. The results suggest that intraperitoneal administration of the leaf extracts of P. granatum at 50 or 100 mg kg(-1) dose clearly enhance the innate immune responses and disease resistance after 8 weeks in P. olivaceus against natural LDV infection.

Effect of traditional Korean medicinal (TKM) triherbal extract on the innate immune system and disease resistance in Paralichthys olivaceus against Uronema marinum.

We report the effect of aqueous-, ethanol- and methanol-solvent-derived extracts of three traditional Korean herbs, Punica granatum, Chrysanthemum cinerariaefolium and Zanthoxylum schinifolium, by monitoring the innate immune mechanisms, such as phagocytosis activity, respiratory burst activity, alternative complement activity and lysozyme activity and the functional immunity in terms of percentage mortality and relative percent survival (RPS) in olive flounder (Paralichthys olivaceus) against Uronema marinum (1 x 10(5)ciliates ml(-1)) for 30 days. Fish were intraperitoneally administered with 5, 50 and 100 mg kg(-1) body weight of each traditional Korean medicinal (TKM) solvent extract except the control and infected untreated groups. In all the treated groups at concentrations of 50 and 100 mg kg(-1) body weight, the chosen innate immune parameters were found significantly enhanced when compared to 0 mg kg(-1) dose. However, at 5 mg kg(-1) the tested immune parameters did not vary. Administration of TKM solvent extracts preceding the challenge with U. marinum for 30 days significantly reduced the percentage mortality with the consequent increase in RPS. Administration of 50 and 100 mg kg(-1) TKM solvent extracts clearly enhanced the innate immune responses and disease resistance in P. olivaceus against U. marinum.

Dietary administration of Zooshikella sp. enhance the innate immune response and disease resistance of Paralichthys olivaceus against Sreptococcus iniae.

We report the growth, innate immune response, and disease resistance in olive flounder (Paralichthys olivaceus) challenged with Streptococcus iniae after feeding with diet enriched with Zooshikella sp. strain JE-34 three different concentration i.e. Low (3.4 x 10(4), n = 50), medium (3.5 x 10(6), n = 50), and high (3.4 x 10(8), n = 50) cfu ml(-1) supplemented diets, the changes were monitored on weeks 1, 2, 4, 8, 12, and 16. With all diets the innate immune parameters, such as superoxide anion production, phagocytic and lysozyme activity were not enhanced on week 1 and 4. On the other hand, all tested immune parameters in the treated groups significantly enhanced after 8th week; the weight gain significantly increased after 4th week in fish fed with enriched diets. The mortality in olive flounder after administration with high concentration diet showed 25%. With low and medium enriched diets the mortality was 40% and 35%, respectively. In the infected untreated group mortality was 85% while there was no mortality in the control group. The results suggested that Zooshikella sp. strain JE-34 enriched diets could be used to enhance the innate immune response and disease resistance of P. olivaceus against S. iniae.

Phytotherapy of ulcerative dermatitis induced by Aeromonas hydrophila infection in goldfish ( Carassius auratus ).

Goldfish ( Carassius auratus ) weighing 13 +/- 2 g were administered intramuscularly a sublethal dose (1.8 x 10 3 cfu/ml) of Aeromonas hydrophila to induce ulcerative dermatitis. On day 3 and day 6 after infection the fish were dip-treated (for 5 min/day) with a tri-herbal concoction of Curcuma longa, Ocimum sanctum and Azadirachta indica (1%). The LD 50 value was recorded at a concentration of 2.3 x 10 4 between 30 and 36 days after infection. In the infected untreated group the cumulative mortality was higher, while in the early-treated group (day 3) there was no mortality. In the late-treated group (6th day) the mortality increased to 23.3% on day 36. In the infected group the size of ulcers progressively increased from 43.3% of the body length on day 18 to 86.7% on day 36. In the early-treated fish the size of ulcers was 23.3% of the body length on day 18; by day 36 after treatment the ulcer had completely healed. In contrast, there was only a moderate recovery in the late-treated group. From the results it can be concluded that early tri-herbal treatment ensures successful recovery from ulcerative dermatitis induced by A. hydrophila .

Effect of a mixed herb-enriched diet on the innate immune response and disease resistance of Paralichthys olivaceus against Philasterides dicentrarchi infection.

We investigated the effect of a mixed herb-enriched diet obtained from pomegranate Punica granatum, Dalmatian chrysanthemum Chrysanthemum cinerariaefolium, and mastic-leaved prickly-ash Zanthoxylum schinifolium on innate immune mechanisms (e.g., phagocytosis activity, respiratory burst activity, alternative complement activity, lysozyme activity, and disease resistance) of olive flounder Paralichthys olivaceus against the scuticociliate Philasterides dicentrarchi. All experimental groups were challenged with P. dicentrarchi (1 x 10(5) ciliates/mL) through intraperitoneal administration of the pathogen (50 microL) on day 1. On day 7, the infected groups were fed 0, 5, 50, and 100 mg/kg of the enriched diets. The innate immune parameters, cumulative mortality, and relative percent survival (RPS) were assessed at weeks 1, 2, 3, and 4. Administration of 50 or 100 mg/kg of the herbal-enriched diet enhanced immunity throughout the experimental period. However, at the 5-mg/kg dosage, the enriched diet did not enhance the innate immune estimates at any time. At doses of 50 and 100 mg/kg, administration of the diet preceding the challenge with P. dicentrarchi decreased the percentage cumulative mortality in the experimental groups and thereby increased RPS values. This study reports that administration of 50 or 100 mg/kg mixed herbal-enriched diet could positively influence the innate immune response to P. dicentrarchi and enhance the health status of olive flounder with respect to this microbe.

Innate immune response and disease resistance in Carassius auratus by triherbal solvent extracts.

This study reports the effect of aqueous, ethanol and methanol triherbal solvent extract from Azadirachta indica, Ocimum sanctum and Curcuma longa on innate immune mechanisms such as phagocytosis activity, respiratory burst activity, alternative complement activity and lysozyme activity and disease resistance in goldfish (Carassius auratus) against Aeromonas hydrophila. Fish were intraperitoneally injected with different doses of 0, 5, 50 and 100 mg kg(-1) body weight of each triherbal solvent extracts. The functional immunity in terms of percentage mortality and Relative Percent Survival (RPS) and innate immune response was assessed on week 1, 2 and 4 by challenging with live A. hydrophila (1 x 10(7) cells ml(-1)). All the chosen innate immune parameters were enhanced in the ethanol and methanol triherbal solvent extract treatment after week 2. However, the aqueous triherbal extract was enhanced only after week 4. The ethanol and methanol triherbal solvent extracts administration preceding the challenge with live A. hydrophila decreased the percentage mortality in the experimental groups with the consequence increase in RPS values. The study indicates that all the doses of ethanol or methanol triberbal solvent extracts could be positively influence the immune response and protect the heath status of goldfish against A. hydrophila infection.
