DOI
:10.4103/0973-1296.165551
PMID
:26600713
Background:
Abnormal Savda Munziq (ASMq) is a traditional Uyghur herbal preparation used as a therapy for abnormal Savda-related diseases. In this study, we investigate ASMq's dynamic effects on abnormal Savda rat models under different disease conditions.
Materials and Methods:
Abnormal Savda rat models with hepatocellular carcinoma (HCC), type 2 diabetes mellitus (T2DM), and asthma dosed of ASMq. Serum samples of each animal tested by nuclear magnetic resonance spectroscopy and analyzed by orthogonal projection to latent structure with discriminant analysis.
Results:
Compared with healthy controls, HCC rats had higher concentrations of amino acids, fat-related metabolites, lactate, myoinositol, and citrate, but lower concentrations of α-glucose, β-glucose, and glutamine. Following ASMq treatment, the serum acetone very low-density lipoprotein (VLDL), LDL, unsaturated lipids, acetylcysteine, and pyruvate concentration decreased, but α-glucose, β-glucose, and glutamine concentration increased (
P
< 0.05). T2DM rats had higher concentrations of α- and β-glucose, but lower concentrations of isoleucine, leucine, valine, glutamine, glycoprotein, lactate, tyrosine, creatine, alanine, carnitine, and phenylalanine. After ASMq treated T2DM groups showed reduced α- and β-glucose and increased creatine levels (
P
< 0.05). Asthma rats had higher acetate, carnitine, formate, and phenylalanine levels, but lower concentrations of glutamine, glycoprotein, lactate, VLDL, LDL, and unsaturated lipids. ASMq treatment showed increased glutamine and reduced carnitine, glycoprotein, formate, and phenylalanine levels (
P
< 0.05).
Conclusion:
Low immune function, decreased oxidative defense, liver function abnormalities, amino acid deficiencies, and energy metabolism disorders are common characteristics of abnormal Savda-related diseases. ASMq may improve the abnormal metabolism and immune function of rat models with different diseases combined abnormal Savda.

Curcumin attenuates chronic ethanol-induced liver injury by inhibition of oxidative stress via mitogen-activated protein kinase/nuclear factor E2-related factor 2 pathway in mice
p. 707
Zhang E Xiong, Wei Guo Dong, Bao Ying Wang, Qiao Yun Tong, Zhong Yan Li
DOI
:10.4103/0973-1296.165556
PMID
:26600714
Objective:
This study aimed to investigate the protective effect of curcumin on chronic ethanol-induced liver injury in mice and to explore its underlying mechanisms.
Materials and Methods:
Ethanol-exposed Balb/c mice were simultaneously treated with curcumin for 6 weeks. Liver injury was evaluated by biochemical and histopathological examination. Lipid peroxidation and anti-oxidant activities were measured by spectrophotometric method. Anti-oxidative genes expression such as NAD(P)H quinone oxidoreductase 1 (NQO1), heme oxygenase-1 (HO-1), and superoxide dismutase (SOD) were determined by real-time polymerase chain reaction. The nuclear factor E2-related factor 2 (Nrf2) and the phosphorylation states of specific proteins central to intracellular signaling cascades were measured by western blotting.
Results:
Curcumin treatment protected liver from chronic ethanol-induced injury through reducing serum alanine aminotransferase and aspartate aminotransferase activities, improving liver histological architecture, and reversing lipid disorders indicated by decrease of triglyceride, total cholesterol and low-density lipoprotein-cholesterol levels and increase of High-density lipoprotein-cholesterol levels. Meanwhile, curcumin administration attenuated oxidative stress via up-regulating SOD and glutathione peroxidase activities, leading to a reduction of lipid hydroperoxide production. In addition, curcumin increased Nrf2 activation and anti-oxidative genes expressions such as NQO1, HO-1, and SOD through inducing extracellular signal-regulated kinase (ERK) and p38 phosphorylation.
Conclusion:
Our data suggested that curcumin protected the liver from chronic-ethanol induced injury through attenuating oxidative stress, at least partially, through ERK/p38/Nrf2-mediated anti-oxidant signaling pathways.

Lactarius deliciosus
(L. ex Fr.) Gray
p. 716
Xiang Ding, Yiling Hou, Wanru Hou, Yuanxiu Zhu, Lei Fu, Hongqing Zhu
DOI
:10.4103/0973-1296.165559
PMID
:26600715
Background:
Oligosaccharides are composed of a variable number of monosaccharide units and very important in the biologically diverse of biological systems.
Materials
and
Methods:
Crude water-soluble oligosaccharide was extracted from the fruiting bodies with water and then successively purified by DEAE-cellulose 52 and Sephadex G-100 column chromatography, yielding one major oligosaccharides fractions: LES-A. Structural features of
Lactarius deliciosus
(L. ex Fr.) Gray oligosaccharide (LDGO-A) were investigated by a combination of monosaccharide component analysis by thin layer chromatography, infrared spectra, nuclear magnetic resonance spectroscopy, scanning electron microscopy, and high-performance gel permeation chromatography analysis.
Result:
The results indicated that LDGO-A was composed of D-glucose and D-xylose, and the average molecular sizes was approximately 945 Da. The anti-tumor activity of LDGO-A was evaluated
in vivo
. The inhibitory rate in mice treated with 40 mg/kg LDGO-A can reach 40.02%, being the highest in the three doses, which may be comparable to mannatide. Histology of immune organs shows that the tissues arranged more regular and firmer, but the tumor tissue arranged looser in LDGO-A group than those in the control group. Meanwhile, there is no obvious damage to other organs, such as heart. The anti-tumor activity of the LDGO-A was usually believed to be a consequence of the stimulation of the cell-mediated immune response because it can significantly promote the lymphocyte and macrophage cells in the dose range of 100-400 μg/mL
in vitro
. LDGO-A also effected the expression of some housekeeping genes mRNA in S180 tumor.
Conclusion:
Accordingly, the LDGO-A might serve as an effective healthcare food and source of natural anti-tumor compounds.

in vivo
has not been investigated.
Objective:
Our aim was to investigate the antagonistic effect of fermented CS on OS in doxorubicin (DOX) treated rats and to compare the anti-OS effects in heart and liver tissues.
Materials and Methods:
OS rats were induced by tail-intravenous injection of DOX (total of 7.5 mg/kg), and then administered intragastrically with fermented CS (1.5 g/kg) for 4 weeks. At the end of the experiment, heart, liver and serum samples were taken for and biochemical analyses.
Results:
Fermented CS significantly increased the activities of glutathione peroxidase and catalase and the scavenging activity of O2
−
in serum, and the total superoxide dismutase activity in cardiac tissue; reduced the malondialdehyde content in liver and cardiac tissues.
Conclusion:
Fermented CS can inhibit DOX-induced OS reactions, and the anti-OS effects have high selectivity to heart and liver, especially to heart. Thus, fermented CS may be a candidate used for the prevention against various cardiac diseases induced by OS.

Background:
Recently we found the ethanolic extract and iridoid-rich fraction from
Valeriana
jatamansi
Jones, which is a traditional Chinese medicine exhibited anxiolytic properties.
Objective:
This study aims to the substance dependence effect of the ethanolic extract and iridoid-rich fraction.
Materials
and
Methods:
The study included two experiments: Mice were given orally with ethanolic extract for 12 weeks or iridoid-rich fraction for 16 weeks in experiment I and experiment II, respectively. Diazepam was used as a control drug and the normal mice groups were administered with 0.5% carboxymethyl cellulose Na in both experiments. All groups were administered twice daily. Natural withdrawal symptoms, withdrawal-induced body weight change, audiogenic tail-erection test (in experiment I), and pentylenetetrazol (PTZ)-induced convulsion test (in experiment II) were measured.
Results:
(1) Compared to normal group in both experiments, the diazepam-treated group exhibited obvious withdrawal symptoms of tail-erection, irritability, teeth chattering, etc; the body weight of them after withdrawal had a period of significant loss (
P
< 0.05 or
P
< 0.01); and the ratios of tail-erection and seizure in two experiments were improved significantly when mice were induced by mixer noise ringtone (experiment I) or PTZ (experiment II) (
P
< 0.05 or
P
< 0.01).(2) In experiment I and II, there were no significant differences between mice that received ethanolic extract or iridoid-rich fraction and normal group in terms of natural withdrawal symptoms and withdrawal-induced body weight change (
P
> 0.05); in audiogenic tail-erection test, it found that the significant difference compared with normal group was just in ethanolic extract 900 mg/kg dose group on week 8 (
P
< 0.05); in PTZ-induced convulsion test, mice in iridoid-rich fraction groups had a slightly tail-erection and seizure, all results of them were with no significant difference compare to normal mice (
P
> 0.05), while significant lower than diazepam group (
P
< 0.01).
Conclusion:
(1) The two experiments successfully established the physical dependence of diazepam by gradually increasing the dose.(2)There were just a few mice received with ethanolic extract for 12 weeks or iridoid-rich fraction for 16 weeks appearing some slight withdrawal symptoms after precipitated withdrawal, but it didn't show significant difference compared to normal mice. Therefore, these indicated that the risks of potential drug dependence about ethanolic extract and iridoid-rich fraction were far lower than that of diazepam.
