Abstract
Idiopathic lung fibrosis (ILF) is a severe and life threatening lung disorder that is characterized by scarring of lung tissue, leading to thickening and stiffening of affected areas. This study looked at the role played by PI3K-Akt/PKB-mToR signaling pathway in the pathogenesis of N-Nitrosodimethylamine (NDMA)-induced lung fibrotic injury, and the effects of syringic acid (SYR) and ascorbic acid (ASC) treatments in male Wistar rats. Pulmonary fibrosis was induced by intraperitoneal injection of 10 mg/kg NDMA once daily, thrice (consecutively) a week for four weeks, and this condition was treated daily with SYR (50 mg/kg) and ASC (100 mg/kg) acids orally for four weeks. Fibrogenesis, following NDMA administration was marked by a significant increase in collagen-1 and α-SMA levels, while oxidative stress was marked by a significant decrease in GSH level, GST, GPx, CAT, and SOD activities. Also, NDMA significantly increased lung Bax, p53, caspase-3, TNF-α, IL-1β, NFkB, and decreased Bcl-2, mdm2, cyclin D1 and Nrf-2 levels. Looking at the PI3K-Akt-mTOR signaling pathway, NDMA administration significantly activated lung PI3K, Akt, and mTOR, and deactivated PTEN, FoxO1 and TSC2. Treatments with SYR and ASC significantly reduced oxidative stress by restoring the antioxidant systems via Nrf2 activation, decreased the levels of inflammatory markers through inhibition of NFkB, downregulated p53, Bax, and caspase-3 via up-regulation of mdm2 and cyclin D1. SYR and ASC also regulated the PI3K-Akt-mTOR signaling pathway via the deactivation of PI3K, Akt, and mTOR, and up-regulation of PTEN, FoxO1 and TSC2. Overall, SYR and ASC modulate the PI3K-Akt-mTOR signaling pathway via inhibition of oxidative stress, inflammation and apoptosis in NDMA-induced lung fibrosis.

Abstract
Dimethylnitrosamine (DMN) is an established carcinogen. It is toxic to several organs, viz., the liver, kidney, and lungs, and immune system. Several drugs have been used in the past to modulate its toxicity using experimental animal models. The present study was designed to investigate the effect of zinc oxide nanoparticles (ZnONPs) on renal toxicity caused by DMN in laboratory rat. Since oxidative mechanisms are mainly involved in its toxicity, the proposed study focuses on the amelioration of oxidative stress response by ZnONPs, if any. The present results show that administration of ZnONPs (50 mg/kg body weight/rat) to DMN (2 μl/100 g body weight/rat)-treated rats diminuted the concentration of malonaldehyde, H2O2, and NO in the kidney. However, reduced glutathione (GSH) concentration increased after ZnONP treatment. Results on glutathione S-transferase and glutathione peroxidase favored its antioxidative effects. These results are supported by the recovery of oxidative DNA damage and less pronounced histopathological changes in the kidney. It is hypothesized that ZnONPs might be toxic to renal tissue; however, its strong therapeutic/antioxidative potential helps in ameliorating DMN-induced renal toxicity in rat.

Abstract
OBJECTIVES For designing early treatment for liver cancer, it is important to prepare an animal model to evaluate cancer prevention treatment by using inflammation disease. The hepatocarcinogenic N-Nitrosodiethylamine (NDEA) has been reportedly able to produce free radicals that cause liver inflammation leading to liver carcinoma. This study aimed to evaluate the inflammation disease model of mice induced with hepatocarcinogenic NDEA for five weeks induction. METHODS The BALB-c mice were induced with NDEA 25 mg/kg of body weight once a week for five weeks intraperitonially and it was then evaluated for the body weight during study periods. The mice were then sacrificed and excised for evaluating their organs including physical and morphological appearances and histopathology evaluations. RESULTS The results showed a significant decrease of body weight of mice after five times induction of 25 mg NDEA/kgBW per week intraperitonially. Different morphological appearances and weight of mice organs specifically for liver and spleen had also been observed. The histopathology examination showed that there were hepatic lipidosis and steatohepatitis observed in liver and spleen, respectively that might indicate the hepatocellular injury. CONCLUSIONS It can be concluded that inducing mice with NDEA intraperitonially resulted in fatty liver disease leading to progress of cancer disease.

Abstract
Dimethylnitrosamine (DMN) is a potent hepatotoxic, carcinogenic and mutagenic compound. It induces massive liver cell necrosis and death in experimental animals. Several drugs have been tested in the past for their protective behavior against DMN toxicity. However, it is for the first time that therapeutic intervention of ZnONPs (zinc oxide nanoparticles) has been studied against its toxicity. Present results show that a post treatment of ZnONPs (50 mg/kg) to DMN (2 μl/100 g body weight) treated rats reduces lipid peroxidation, oxidative stress and fibrosis in the liver. It diminishes serum ALT (alanine transaminases), AST (aspartate transaminases) and LDH (lactate dehydrogenase) showing improvement in liver function. Reduced values of proinflammatory cytokines viz. TNF-α and IL-12 also support its protective effects. Histopathological observations also indicate improvement in liver cell morphology. It is postulated that ZnONPs offer protection through selective toxicity to proliferating tissue including adenomatous islands formed in the liver. Zinc metallothionein (Zn-MT) induced by ZnONPs may also contribute in the amelioration of DMN induced toxic effects. Diminution of oxidative stress by ZnONPs remains to be the key mechanism involved in its protective effects. However, toxicity of ZnONPs in the liver needs to be monitored simultaneously.

Abstract
The present study was designed to evaluate the hepatoprotective potential of α-lactalbumin (αLA) against dimethylnitrosamine (DMN)-induced toxic insults in the rat liver. The liver damage was induced in rats by the repeated administration of DMN (10 mg/kg, i.p.) on three consecutive days per week for three weeks. The rats were maintained on either a standard AIN-93 M or αLA-enriched diet starting one week before the DMN injection until the termination of the experiment. The DMN treatment produced a progressive increase in the plasma markers (aspartate aminotransferase, alanine aminotransferase, total bililbin, hyarulonic acid, and matrix metalloproteinase-2) in 28 days after the first DMN injection. Dietary treatment with αLA significantly reduced the DMN-induced damage toward normalcy. NG-nitro-L-arginine methyl ester, a nitric oxide synthase inhibitor, significantly attenuated the hepatoprotective effect of αLA. These findings show that αLA has a marked suppressive effect on hepetic fibrosis through a nitric oxide-mediated mechanism.

Abstract
Oxidative stress in liver injury is a major pathogenetic factor in the progression of liver damage. Centella asiatica (L.) Urban, known in the United States as Gotu kola, is widely used as a traditional herbal medicine in Chinese or Indian Pennywort. The efficacy of Centella asiatica is comprehensive and is used as an anti-inflammatory agent, for memory improvement, for its antitumor activity and for treatment of gastric ulcers. The present study investigated the protective effects of Centella asiatica on dimethylnitrosamine (DMN)-induced liver injury in rats. The rats in the treatment groups were treated with Centella asiatica at either 100 or 200 mg/kg in distilled water (D.W) or with silymarin (200 mg/kg in D.W) by oral administration for 5 days daily following intraperitoneal injections of 30 mg/kg DMN. Centella asiatica significantly decreased the relative liver weights in the DMN-induced liver injury group, compared with the control. The assessment of liver histology showed that Centella asiatica significantly alleviated mass periportal ± bridging necrosis, intralobular degeneration and focal necrosis, with fibrosis of liver tissues. Additionally, Centella asiatica significantly decreased the level of malondialdehyde, significantly increased the levels of antioxidant enzymes, including superoxide dismutase, glutathione peroxidase and catalase, and may have provided protection against the deleterious effects of reactive oxygen species. In addition, Centella asiatica significantly decreased inflammatory mediators, including interleukin (IL)-1β, IL-2, IL-6, IL-10, IL-12, tumor necrosis factor-α, interferon-γ and granulocyte/macrophage colony-stimulating factor. These results suggested that Centella asiatica had hepatoprotective effects through increasing the levels of antioxidant enzymes and reducing the levels of inflammatory mediators in rats with DMN-induced liver injury. Therefore, Centella asiatica may be useful in preventing liver damage.

Abstract
Information on dimethyl nitrosamine (DMN)-induced toxicity on endocrine functions is still scanty. This study therefore investigated the outcomes of DMN-induced toxicity on endocrine (thyroid and reproductive) functions, as well as kallikrein-3 level, and effects of ascorbate treatments in male wistar rats. Thirty animals divided into six groups of five rats each were used. Group I animals were the normal control, group II animals served as vehicle control and were administered a single intraperitoneal dose of normal saline, groups III and IV were intraperitoneally injected with a single dose of 30 mg/kg DMN for 48 h, but group IV animals were post-treated orally with 5.71 mg/kg body weight (400 mg/70 kg) ascorbate for seven days, group V animals were pre-treated with same dose of ascorbate orally for seven days before intraperitoneal injection of DMN, while group VI animals were orally administered ascorbate only for seven days. Compared with control, DMN administration resulted in significant decrease (p < 0.05) in serum total cholesterol, testosterone (TST), luteinizing hormone (LH), free triiodothyronine (fT3), and kallikrein III (KLK-3) levels, as well as non-significant increase in serum thyroid stimulating hormone (TSH) level. Pre-treatment with ascorbate significantly increase LH and KLK-3 levels, while post-treatment significantly increase fT3 level. Also, pre-treatment with ascorbate significantly reduced TSH level, while there was no significant difference in TST level following ascorbate treatments. From our findings and to some extent, ascorbate demonstrates ameliorative effects against DMN-induced hormonal disruption in male wistar rats, and this may be attributed to its antioxidant property. DMN administration significantly decreased serum total cholesterol, testosterone (TST), luteinizing hormone (LH), free triiodothyronine (fT3), and kallikrein III (KLK-3) levels. Pre-treatment with ascorbate significantly increases LH and KLK-3 levels. Ascorbate post-treatment and pre-treatment significantly increased fT3 and decreased TSH levels respectively.

Abstract
AIM A decoction of Elephantopus scaber (Asteraceae) root is used to treat liver disorders in Indian and Chinese traditional medicine. The study was designed to examine the dose response effects of E. scaber methanolic extract on rats exposed to N-nitrosodiethylamine (NDEA) induced hepatotoxicity (0.02% NDEA in water five days per week, per oral) in preventive and curative models. METHODS In preventive groups, NDEA was administered for six weeks. Daily doses of E. scaber methanolic extract (200 and 100 mg·kg-1) started one week before the onset of NDEA intoxication and continued for six weeks. In curative animals, NDEA was administered for six weeks followed by treatment with the methanolic n-hexane extract of E. scaber (200 and 100 mg·kg-1) for ten days. RESULTS E. scaber extract treatment significantly (P ≤ 0.05) reduced the levels of AST, ALT, and MDA in both experimental groups. The extract also enhanced the antioxidant enzyme and protein levels in rats intoxicated with NDEA. Treatment with the extract dose dependently protected the liver from NDEA-induced hepatotoxicity with normal hepatocytes and uniform sinusoids, but in some areas showed degenerating hepatic cells in both treatment groups. CONCLUSION E. scaber methanolic extract dose dependently prevented and reversed the hepatotoxicity induced by NDEA in both experimental models.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Astragalus membranaceus and Salvia miltiorrhiza have been used for centuries in China to treat liver diseases. Previous studies have shown that these herbs and their extracts inhibit the development of liver fibrosis and the proliferation and invasion of human hepatoma HepG2 cells. Further study of their pharmacological effects on hepatocellular carcinoma (HCC) is needed. To investigate the effects of Compound Astragalus and Salvia miltiorrhiza Extract (CASE) on diethylinitrosamine (DEN)-induced hepatocarcinogenesis in rats. MATERIALS AND METHODS Male rats were divided into five groups, with the first group serving as normal control, the second group receiving 0.2% DEN solution five times a week for 14 weeks, and the third to fifth group receiving the same DEN as in the second group together with CASE at the doses of 60, 120, and 240 mg/kg per day for 16 weeks, respectively. Hepatoma incidence, serum enzymes levels, degree of fibrosis and hydroxyproline content were evaluated and compared across the five groups to determine CASE's suppression of fibrosis and HCC progression. In addition, an in vitro experiment using HepG2 cells was conduct to verify CASE's effect on the transcription of plasminogen activator inhibitor-1 (PAI-1) mRNA. RESULTS CASE treatment significantly reduced the incidence and multiplicity of DEN-induced HCC development in a dose-dependent manner. It significantly suppressed the elevation of alanine transaminase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, hyaluronic acid, direct bilirubin and total bilirubin, and significantly lessened the depression of serum total protein in DEN-induced HCC rats. CASE treatment also significantly suppressed the elevated expression of GST-P and α-SMA. The in vitro experiment confirmed that CASE inhibits the transcription of PAI-1 mRNA in HepG2 cells induced by TGF-β1 in a dose-dependent manner. CONCLUSIONS CASE suppresses DEN-induced hepatocarcinogenesis by inhibiting fibrosis and PAI-1 mRNA transcription, suggesting its potential clinical application in preventing and treating human HCC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lygodium flexuosum (Linn) Sw. is a climbing fern, and it is the sole genus in the family Lygodiaceae. It commonly grows epiphytically on moss covered tree trunks and branches as lithophytes on shady boulders along with moss. It has been reported as a traditional folkloric medicine for a variety of ailments particularly useful for carbuncles, inflammation, ulcer, various respiratory diseases, general disorders, muscle sprains and acts as panacea for wounds. However, there are no scientific reports on wound healing activity of the plant L. flexuosum (Linn) Sw. AIM OF THE STUDY To explore the protective effect of L. flexuosum against excision, incision and dead space wounds models in experimental rats. METHODS Wistar albino rats of either sex weighing between 180 and 220 g were topically treated with extract formulated in ointment using simple ointment BP as base. Ointments, 4% and 5% (w/w), were applied once daily in excision wound model. L. flexuosum ethanolic extract was given orally at a dose of 100, 200 and 400 mg/kg in incision and dead space wound healing models. Rats of standard groups were treated with 0.2% nitrofurazone ointment topically. The percentage wound contraction, epithelization time in excision wound model; breaking strength in incision wound model and wet and dry granulation weight, hydroxyproline content were measured. RESULTS Topical application of L. flexuosum in excision wound model increased the percentage of wound contraction, and the epithelization time was decreased. In the incision wound model, the breaking strength of wounds increased and in dead space model the weight of dry and wet granuloma of wounds and hydroxyproline was increased. Conclusively, the data of present study indicated that the leaf extract of L. flexuosum accelerated wound healing in rats and thus supports its traditional use.

Lygodium flexuosum extract down regulates the expression of proinflammatory cytokines in CCl4-induced hepatotoxicity. ASIAN PAC J TROP MED 2012; 5:421-6. [PMID: 22575972 DOI: 10.1016/s1995-7645(12)60072-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2011] [Revised: 01/15/2012] [Accepted: 03/15/2012] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE To examine the downregulation of proinflammatory cytokines in a time-dependent manner on carbon tetrachloride induced toxicity in experimental animals. METHODS CCl(4) (150 μL/100 g) was dissolved in corn oil (1:1 v/v %) and administered orally. Group I was treated as normal control and received corn oil on 8th day. Group II was toxic control and was given a single dose of CCl(4) on 8th days. Group III was treated with Lygodium flexuosum (L. flexuosum) n-hexane extract (200 mg/kg) for 8 days and on 8th day a single dose of CCl(4) was received. Group IV (negative control) received L. flexuosum n-hexane extract (200 mg/kg) alone for 8 days. RESULTS Treatment with n-hexane extract prior to the administration of CCl(4) significantly prevented an increase in serum AST, ALT, LDH activity and lipid peroxidation and prevented the depletion of glutathione (GSH). Rats treated with L. flexuosum had reduced mRNA levels of TGF-β1, TNF-α and IL-1β genes in liver of CCl(4) intoxicated rats when compared to CCl(4) control as evidenced by RT-PCR. CONCLUSIONS The data suggest that L. flexuosum, a widely available fern, significantly reduces CCl(4) induced acute hepatotoxicity by down-regulating the expression of pro-inflammatory cytokines in rats.

Abstract
Fucoidan, a sulfated polysaccharide extracted from various types of brown seaweed, possesses a wide range of pharmacological properties. We investigated the protective effect of fucoidan on dimethylnitrosamine-induced liver fibrogenesis in rats and its mechanism. Liver fibrosis was induced by injecting DMN (10 mg/kg, 3 times per week, I.P.) for 4 weeks, and fucoidan was simultaneously administered (100 mg/kg, 3 times per week, P.O.). The anti-oxidative and anti-inflammatory effects of fucoidan were observed by relative mediators. Fucoidan improved liver fibrosis by inhibiting the expression of transforming growth factor beta 1 (TGF-β(1))/Smad3 and the tissue inhibitor of metalloproteinase 1 (TIMP-1), and increasing the expression of metalloproteinase-9 (MMP-9). Fucoidan also significantly decreased the accumulation of the extracellular matrix (ECM) and collagen. These results suggest that fucoidan had an anti-fibrotic effect, which was exerted by inhibiting the TGF-β/Smad pathway, as well as anti-oxidative and anti-inflammatory effects.

Abstract
Melatonin has potent hepatoprotective effects as an antioxidant. However, the signaling pathway of melatonin in the induction of antioxidant enzymes against acute liver injury is not fully understood. The study aimed to determine whether melatonin could prevent dimethylnitrosamine (DMN)-induced liver injury through nuclear erythroid 2-related factor 2 (Nrf2) and inflammation. Liver injury was induced in rats by a single injection of DMN (30 mg/kg, i.p.). Melatonin treatment (50 mg/kg/daily, i.p.) was initiated 24 hr after DMN injection for 14 days, after which the rats were killed and samples were collected. Serum and antioxidant enzyme activities improved in melatonin-treated rats, compared with DMN-induced liver injury group (P < 0.01). Melatonin reduced the infiltration of inflammatory cells and necrosis in the liver, and increased the expression of NADPH: quinone oxidoreductase-1, heme oxygenase-1, and superoxide dismutase-2, which were decreased by DMN. Melatonin increased expression of novel transcription factor, Nrf2, and decreased expression of inflammatory mediators including tumor necrosis factor-alpha, interleukin (IL)-1beta, IL-6, and inducible nitric oxide synthase. The increased nuclear binding of nuclear factor-kappa B (NF-kappaB) in the DMN-induced liver injury group was inhibited by melatonin. Our results show that melatonin increases antioxidant enzymes and Nrf2 expression in parallel with the decrease of inflammatory mediators in DMN-induced liver injury, suggesting that melatonin may play a role of antioxidant defense via the Nrf2 pathway, by reducing inflammation by NF-kappaB inhibition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lygodium flexuosum (Lygodiaceae), a medicinal fern used in Indian traditional medicine against liver disorders. AIM OF THE STUDY The rationale of the study was to examine whether the n-hexane extract from plant Lygodium flexuosum affects apoptosis on human hepatoma PLC/PRF/5 and Hep 3B cells. MATERIALS AND METHODS Chemopreventive activity of the Lygodium flexuosum extract was determined by MTT assay, annexin-V FITC binding to phosphatidyl serine and cleavage of PARP. Subdiploid condition of cells treated with Lygodium flexuosum was analyzed by flow cytometry. Further, used transiently transfected NF-kappaB reporter in PLC/PRF/5 cells to evaluate the inhibitive effect of Lygodium flexuosum extract. RESULTS Lygodium flexuosum extract inhibited the cell viability and induced apoptosis in hepatoma cells in a concentration dependent manner as evidenced by apoptotic changes such as flipping of phosphatidyl serine, cleavage of PARP. Cell cycle analysis showed the subG1 apoptotic population in cells treated with higher concentrations of the extract. When activated with exogenous TNF-alpha in transfected hepatoma cells it was observed that NF-kappaB dependent gene expression was inhibited by treatment with Lygodium flexuosum extract in PLC/PRF/5 cells dose-dependently. CONCLUSIONS This investigation suggests that the Lygodium flexuosum extract has antiproliferative and apoptotic activity in both cancer cells and has inhibitive role in TNF-alpha induced NF-kappaB activation in PLC/PRF/5 cells confirms the potential of the extract as a chemopreventive agent.

Abstract
AIM OF THE STUDY Phyllanthus rheedii Wight. (Euphorbiaceae) has been used by Muthuvan tribes of Kerala for curing liver diseases. The present study was conducted to assess the hepatoprotective activity of this plant. The ethanol extract of Phyllanthus rheedii was pharmacologically analysed for its preventive effect in d-galactosamine (d-GalN) induced liver damage in rats. MATERIAL AND METHODS The levels of hepatotoxicity in various groups were quantified by different parameters of liver damage viz. serum levels of ALT, AST, LDH, GGT, ALP and total bilirubin. The effect of extract on the expression levels of pro-inflammatory cytokines like TNF-alpha, and TGF-beta were analysed by RT-PCR. Histological changes in the liver were evaluated by hematoxylin and eosin staining of paraffin processed liver sections. The antioxidant and choleretic activity of the extract were also analysed. RESULTS Comparison of serum values of control and extract treated groups have revealed that the d-GalN induced alterations in the serum and liver markers were normalized in extract treatment groups showing hepatoprotective activity of the extract. The extract also prevented the toxin induced histological changes in liver. The mRNA levels of TGF-beta and TNF-alpha in the liver were up regulated by the hepatotoxin. The extract treatment has normalized this change, giving light to the probable mechanism of action of the extract. It has showed marked antioxidant and choleretic activity. Preliminary phytochemical screening has revealed the presence of tannins, flavanoids and phenolics as major components. CONCLUSIONS This study concluded the ethanol extract of P. rheedii could be a promissory candidate for drug development and validated the tribal claim.
