Introduction<\/strong><\/p>\n

A mangrove and mangrove associate plants are proved to have rich of high value secondary metabolites viz, saponins, alkaloids, polyphenols which possess antibacterial, antifungal, antiplasmodial and hepatoprotective activities.1<\/sup><\/p>\n

Suaeda<\/em>\u00a0(Chenopodiaceae) is a genus of plants also known as\u00a0seep weeds,includes annual and perennial herbs or rarely small trees. There are about 110 species in the\u00a0Suaeda<\/em>\u00a0genus (S.<\/em>).2<\/sup> They are distributed on coasts, deserts, lakeside and saline and alkaline land all over the world.<\/p>\n

A number of species have been found to be valuable feed for livestock in arid area like Suaeda pruinosa\u00a0<\/em>Lange, S. vera<\/em> and S. vermiculata,<\/em>3<\/sup> while others have been utilized to desalinize irrigated farmlands like Suaeda maritime.4<\/sup> In Mexico, some species such as Suaeda pulvinata<\/em> are cooked in traditional dishes known as romeritos. Suaeda<\/em> species are commonly used in folk medicine.5-6<\/sup> Some species possess hypoglycemic, anti-inflammatory, hypolipidemic, cardiotonic, antioxidant, antimicrobial and anticancer activity.7-8<\/sup><\/p>\n

In Saudi Arabia it is represented by 9 species according to Boulos.9<\/sup> Five species were found in Al Jouf area represented by; S. aegyptica<\/em>, S. vera and S. vermiculata, S. fruiticosa and S. mollis.10<\/sup><\/p>\n

Suaeda vera\u00a0subspecies\u00a0pruinosa\u00a0(Lange) Bol\u00f2s and Vigo, (1974), are facultative halophytes that tolerate moderate salt soils, dry soils, nitrified and saline (halonitr\u00f3filos) in very sunny places arid climate during May to October.11<\/sup> The specific epithet ”\u00a0pruinosa\u00a0” refers to the presence of\u00a0pruina, which is kind of thin waxy coating on stems and leaves, which offers a glaucous appearance. In the area south of Alicante has been used to make the ”\u00a0stone soda\u00a0” and was said to be\u00a0as good as that made with fine barrilla (Halogetum sativus). The nutritive value of forage species (crude protein ranges) in Suaeda pruinosa Lange is 27.17%.<\/p>\n

Suaeda monoica<\/em> Forssk. ex J. F. Gmel is a salt marsh mangrove herb growing in hypersaline soils. It is smaller in size, simple leaves which are edible. Traditionally, the leaf from S. monoica<\/em> is known to use as a medicine for hepatitis12<\/sup> and scientifically it is reported to be used as ointment for wounds13<\/sup> and possess antiviral activity7<\/sup> because of the presence of triterpenoids and sterols.5<\/sup><\/p>\n

Methanolic extracts of S. monoica<\/em>, exhibits moderate sun protective activity and a safe, effective and affordable sun screen formulation.14<\/sup> Endophytic fungi were isolated from the leaves and stems of S. monoica<\/em> , the isolation was according to the method described by Suryanarayanan et al.(2003).15<\/sup>\u00a0 Phytochemical screening of methanolic extracts from S. monoica, showed the presence of flavonoids, tannins, phenols , polyphenols, steroids and\u00a0 Alkaloids.16<\/sup><\/p>\n

A polysaccharide extracted from the leaves of S. monoica<\/em> showed positive activity against human immune de\ufb01ciency viruses.7, 13<\/sup><\/p>\n

Therefore, the present attempt has been made to identify the phytoconstituent of S. monoica\u00a0<\/em>and Suaeda pruinosa<\/em>extracts and to find out the anti- inflammatory effect of each extract on the rat liver intoxicated by paracetamol overdose.<\/p>\n

Materials and methods<\/strong><\/p>\n

Plant material and preparation of extract <\/strong><\/p>\n

Suaeda <\/em>sp. were collected during months of June, July, 2016-2017 from El Doubia at El Riyadh- El Dallamroad. Air-dried and powdered aerial parts of Suaeda monoica<\/em>and Suaeda pruinosa <\/em>were extracted with petroleum ether. The solvent was evaporated under reduced pressure then extracted with methyl alcohol in H2<\/sub>O(80%), the solvent was stripped off under reduced pressure gave 50 g. The petroleum ether extract 10 g was subjected to subsequent investigation.<\/p>\n

Extract of Amino Acids<\/strong><\/p>\n

Lyophilized tissues were ground in a mortar and extracted with MCW (methanol:chloroform:water 12:5:3 v\/v\/v), following the procedure described by Marur et al.(1994)17<\/sup>. A sample of ground material (100 mg) was extracted with 10 mL of MCW for 3 days in a closed tube in a refrigerator. After centrifugation at 1200 rpm for 5 min on a bench centrifuge, the supernatant was collected and the residue extracted with a further 6 mL of MCW. After centrifugation the supernatants were combined (16mL) and shaken with chloroform (4mL) followed by water (6 mL). On standing, the resulting separation of phases enabled the removal of chlorophyll and the aqueous phase was taken to dryness under a stream of N2<\/sub> gas. This material was resuspended in water and used for amino acid determination.<\/p>\n

Biochemical Studies<\/strong><\/p>\n

Materials and Methods<\/strong><\/p>\n

Drugs and Chemicals Paracetamol was purchased from Alexandria Company for Pharmaceuticals and Chemical Industries. Kits for determination of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP),bilirubin and urea were obtained from Biomed Diagnostics, Egypt. The interleukin-1\u03b2(IL-1\u03b2) and tumor necrosis factor alpha (TNF-\u03b1) were carried out using an ELISA reagent kits obtained from Biosource, USA.<\/p>\n

Animals<\/strong><\/p>\n

Male rats weighing 100-120 g were obtained from theAnimal Breeding Lab of National Research Centre, Cairo, Egypt. The animals were kept under constant temperature conditions (22 \u00b1 2\u00b0C), relative humidity (50\u201360%), and lighting (12 h light\/dark cycle). Food and water were accessible ad libitum. The study was carried out according to the guidelines of the Ethics Committee of the National Research Centre.<\/p>\n

Experimental Design <\/strong><\/p>\n

Six groups each of six male albino rats were selected. Group1: served as negative control. Group 2: rats received a single dose of paracetamol (positive control). Group 3 & 4: rats received Suaeda monoica and Suaeda pruinosebefore paracetamol induction. Group 5 & 6: rats received the Suaeda monoica<\/em> and Suaeda pruinose <\/em>extract after paracetamol induction. Twenty\u2013four hour after treatments, the rats of all groups were anesthetized and blood samples were collected directly from retro-orbital plexus. The blood samples were allowed to clot for 20-30 min. Serum was separated by centrifugation at 37\u00b0C and used for estimation of various biochemical parameters. Animals were sacrificed by decapitation. Livers were rapidly isolated; a part of each was homogenized using cold saline to prepare a 10% homogenate that was used for estimation of malondialdehyde (MDA). The second part of the liver was preserved in 10% formalin for histopathological and histochemical examinations.<\/p>\n

Biochemical Analyses <\/strong><\/p>\n

The activities of AST and ALT were determined according to the method of Reitman and Frankel,(1957).23<\/sup>\u00a0Alkaline phosphatase was determined using the method described by Demetriouet al. (1974).24<\/sup> Bilirubin was carried out by themethod described by Young (2000).25<\/sup> Creatinine was measured by the method of Bartelsand Bohmer (1971).26<\/sup> Urea was calculated by the method of Tabaccoet al. (1979).27<\/sup>\u00a0Arylesterase activity of paraoxonase 1 (POX-1) was measured spectrophotometrically using phenylacetate as a substrate.28-29<\/sup> IL-1\u03b2was carried out using an ELISA reagent kit and expressed as pg\/ml. TNF-\u03b1was determined by ELISA using kit (Biosource International, USA) and microtiter plate reader (Fisher Biotech, Germany). Lipid peroxidation was assayed by measuring the level of malondialdehyde (MDA) in the tissue homogenates using the method of Ruiz-Larrea et al. (1994).30<\/sup><\/p>\n

Histopathological and Histochemical Studies<\/strong><\/p>\n

After the experimental period, animals were sacrificed, liver removed immediately, sliced and washed in saline. Liver pieces were preserved in 10% formalin for histopathological studies. Sections were taken and stained with hematoxylin and eosin (H&E)31<\/sup> and then they were examined for histopathological changes and photographed. The histochemical study was performed by periodic acid-Schiff method32<\/sup> for visualization of the polysaccharidein the liver. These materials were demonstrated in sections with 5 \u03bc m thickness.<\/p>\n

Statistical Analysis<\/strong><\/p>\n

The protection percent is calculated by 1-(T-V\/C-V)x100. Data were expressed as mean \u00b1 SD. The data were analyzed by one-way ANOVA followed by Duncan\u06e5s multiple tests, using SPSS software (SAS Institute Inc., Cary, NC, USA). A probability value of less than 0.05 was considered statistically significant.<\/p>\n

Results and Discussion<\/strong><\/p>\n

Preliminary Phytochemical Analysis <\/strong><\/p>\n

Plant materials were screened using the methods previously described33<\/sup>. Phytochemical analysis gave positive test for alkaloids, terpenoids, steroids, tannins, saponins, flavonoids and phenols. The identification of major chemical groups was carried out by thin layer chromatography (TLC) on silica gel. TLC was developed in chloroform\/methanol\/water (26:14:3), spots were visualized with sulfuric acid 20% in methanol solution under 254 and 356 nm gave yellow spots for Flavonoids, and purple color suggested the existence of triterpene, pink color for sterols and brown color for monoterpenes. Data shown that the main compounds were observed in S. monoica<\/em> and S. pruinosa<\/em>phenolic and terpenes \/or sterols.<\/p>\n

Amino Acids Analysis<\/strong><\/p>\n

Separation of the amino acids for methanolic extracts of each plant was carried out on HPLC system revealed that, the highest percentage of Methionine in S. pruinosa <\/em>(<\/strong>0.999) while S. monoica <\/em>(<\/strong>0.889) and Histidine was (0.216) in S. monoica<\/em> and (0.167) in S.pruinosa <\/em>extracts.

Histopathological Studies <\/strong><\/p>\n

At the end of the experiment, and after blood samples were obtained liver samples were taken, washed with normal saline and processed for histopathological study. Initially the materials were fixed in 10% buffered neutral formalin and paraffin sections were taken at 5 \u00b5m thickness processed in alcohol-xylene series and was stained with alum hematoxylin and eosin, then were examined for histopathological changes.<\/p>\n

The microscopic examination of liver of control rats shows the normal hepatic lobules and portal areas structure. The central vein is surrounded by the hepatocytes with eosinophilic cytoplasm and distinct nuclei. The hepatic sinusoids are shown between the hepatocytes (Fig. 1.A, B).<\/p>\n

Histopathological investigations of liver of rat administered a single dose of paracetamol (3 g\/kg\/b.w) showed widespread swelling and ballooning degeneration and focal necrosis that associated with inflammatory infiltration in the hepatocytes (Fig. 1.C). In some rats dilated and congested portal tracts (Fig. 1.D).<\/p>\n\n\n\n

Examination of control liver sections stained by PAS reaction shows the abundance of glycogen in the cell of hepatic lobule. The glycogen particles appear accumulated at one side of the cytoplasm leaving the other side almost devoid of such materials (Fig. 4.A). Histochemical investigations of liver of rats administered a single dose of paracetamol dose (3 g\/kg body weight) and were sacrificed after 24 h showed markeddiminution in glycogen distribution in the hepatocytes as compared with control group(Fig. 4.B). Examination of sections of liver that stained with PAS in rat orally given paracetamol after 7 days of Sum and Sup plants extracts administration (prophylactic groups, 100 mg\/kg b.w) indicated an increase in glycogen contents as compared with paracetamol only. The distribution of this inclusion was more or less like normal control (Fig. 4C, D). On the other hand, in case of therapeutic groups in which paracetamol was conducted once before Sum and Sup plant extracts administration (100 mg\/kg b.w) daily for 7 days showed heterogeneous distribution of glycogen, where the healthy zones exhibited normal distribution and the injured zones exhibited a decrease in this inclusion (Fig. 4E, F).<\/p>\n\n\n\n

Biochemical Studies<\/strong><\/p>\n

Liver regulates many important metabolic functions and contains a host of enzymes. Any injury in this organ causes distortion of these metabolic functions. The present work aimed to compare the possible hepatoprotective impact of Suaeda<\/em> Sp. administered for one week prior to and after a single acetaminophen toxic dose (3g\/kg body weight) in male rats.<\/p>\n

The present study showed damage of liver due to paracetamol over dosage which is confirmed by elevated levels of all biochemical parameters measured (SGPT, SGOT, ALP, TB, urea, creatinine, IL1, TNF and MDA). The study also showed decrease in POX enzyme. These elevated enzymatic activities in serum, are indicators of cellular leakage and loss of functional integrity of cell membrane in liver.35<\/sup>\u00a0Aqueous extract of S. monoica<\/em> and S. peruinosa<\/em> contain alkaloids, terpenoids, steroids, tannins, quinones, saponins, flavonoids and phenols. They can scavenge off free radicals which are the principles for the hepatoprotective activity for protection or therapeutic effect. Decreased serum parameters level following extract treatment indicated the effectiveness of the extract in restoring normal functional status of the liver.<\/p>\n

Suaeda<\/em> had successfully reversed the PCM-induced hepatotoxic effect by its ability to reduce the elevated levels of ALT, AST, and ALP suggesting that these biochemical restorations could be due to the extract ability to inhibit the cytochrome P450 or\/and ability to promote the PCM glucuronidation.36-37<\/sup>\u00a0Furthermore, the ability to lower the enzymes level can be associated with the ability of Suaeda<\/em> to prevent lipid peroxidation of endoplasmic reticulum that is rich in polyunsaturated fatty acid by disrupting the binding of activated radicals to the macromolecules. This process can possibly be achieved via the antioxidant activity of Suaeda<\/em> extracts due to the presence of high amount of \u03b1 linolenic and linoleic fatty acid.38<\/sup>\u00a0Besides, mechanisms of protection that can take place include activation of liver regeneration by enhancing the protein and glycoprotein synthesis or accelerated detoxification and excretion,39<\/sup>\u00a0prevention of lipid peroxidation process, and stabilization of hepatocellular membrane.38\u00a0<\/sup>The two Suaeda<\/em> extracts contain methionine and cysteine amino acids which act as -SH donner in synthesis of GSH and prevent APAP metabolite to interact with macromolecules. The results are confirmed with Di Pierro and Rossoni, (2013) who found that a mixture of L-cysteine, L-methionine, and L-serine was effective at a lower dose than N- acetyl cysteine (NAC) in APAP over dose and improved mouse survival rates. Moreover, the mixture significantly reduced ALT level and induced hepatic GSH synthesis and decrease MDA accumulation.40<\/sup><\/p>\n

Increase in serum level of ALP is due to increased synthesis in the presence of increasing biliary pressure41<\/sup> and reflects the pathological alteration in biliary flow.42<\/sup><\/p>\n

Bilirubin, a metabolic product of hemoglobin, undergoes conjugation with glucuronic acid in hepatocytes to increase its water solubility. Determination of serum bilirubin represents an index for assessment of hepatic function, and any abnormal increase in the levels of serum bilirubin indicates hepatobiliary diseases and severe disturbance of hepatocellular function.43<\/sup>Decreased serum bilirubin level following extract treatment indicated the effectiveness of the extract in restoring normal functional status of the liver.<\/p>\n

Paracetamol-induced toxicity in rats may have altered membrane structure and function as well as lipids metabolism in the liver.<\/p>\n

Therefore, it is possible to propose that the extract\/compounds exerting an anti-inflammatory activity might also demonstrate hepatoprotective activity. Interestingly, this is supported by the study of Gupta et al. 2006<\/a> who suggested that the combination of hepatoprotective effect and antioxidant activity synergistically prevents the process of initiation and progression of hepatocellular injury in prophylactic and therapeutic treatments.44<\/sup><\/p>\n

Vanillin, a phenolic aldehyde has been reported to possess antioxidant and free radical scavenging ability which could possibly account for the hepatoprotective property of this plant. The activities of antioxidant counteract the redox state precipitated intracellularly and hence ensure hepatoprotection against paracetamol-induced liver injury.45-47<\/sup>\u00a0The antioxidant activity of this extract may also explain the mechanism of the hepatoprotective activity of Suaeda sp.<\/em> The findings of this study corroborate the effect that was reported for Homalium zeylanicum.<\/em>48<\/sup><\/p>\n

Lipid peroxidation (LPO) is one of the characteristic features of oxidative stress in PCM hepatotoxicity. According to Luqman and Rizvi (2006), LPO is known to injure the cells by inactivation of membrane enzymes, decrease fluidity of the membrane and release, into cytotoxic, aldehydes such as MDA.49<\/sup>\u00a0The elevated level of hepatic MDA has been regarded as an indicator of cellular damage and indicates the inability of the antioxidant defense system to protect against the production of excessive free radicals. In this study, MDA increased and POX decreased as a result of paracetamol over dose. The enhanced antioxidant defense in addition to reduced LPO product in the liver is indicative for the antioxidant effect of the tested extracts.<\/p>\n

The biochemical results were supported by the histopathological findings. The results demonstrated that rats exposed to PCM alone showed severe cellular damage that might be due to the production of free radicals by PCM and subsequent LPO. These histopathologic findings were ameliorated significantly in the groups of rat wither were pre-treated or treated with either S. monoica<\/em> or S. peruisma<\/em> extracts, indicating pronounced protection of hepatocytes against PCM induced hepatic damage. It can be referred to the antioxidant effect of the tested extracts that markedly decreased the oxidative stress and thereby reduced the histopathological alterations of the liver.<\/p>\n

The present study found that two Suaeda<\/em> contain cysteine and Methionine with excessive amount which considered as -SH donner for GSH synthesis. Di Pierro and Rossoni (2013) found that DDM-GSH ( amixture of L-cysteine, L-methionine, and L-serine in a weight ratio of 2:1:1) was effective at a lower dose thanN-acetylcysteine (NAC) in reducing APAP-induced hepatotoxicity; improving mouse survival rates, decreasing sALT and MDA accumulation and increase hepatic GSH synthesis in the mouse model.40<\/sup><\/p>\n

Suaeda sp. may inhibit the activity of certain cytochrome P450 enzymes whose inhibition could safeguard against APAP hepatotoxicity.37<\/sup>\u00a0With regard to the potential hepatoprotective effects of Suaeda<\/em>, it was demonstrated that rats which were chronically supplemented with Suaeda extract (100 mg\/kg) and APAP (3 g\/kg ) exhibited an improvement in APAP-induced liver necrosis and increased serum ALT and AST levels.50<\/sup>\u00a0In the present study, paracetamol hepatotoxicity was associated with an increase in serum level of IL1\u03b2.Similar results were reported by other investigators.51-52<\/sup><\/p>\n

Signaling through the IL-1 receptor (IL-1R) was recently shown to play an important role in paracetamol-induced hepatotoxicity.53<\/sup>\u00a0Activation of NF-kB\/Rel transcription factor leads to the increased production of various inflammatory mediators, including IL1 \u03b2 and TNF-\u03b1.54<\/sup><\/p>\n

Activation of Toll-like receptors (TLRs) by pathogen-associated molecular patern results in upregulation of pro- IL1 \u03b2 via NF-k<\/sub>B pathway. This is followed by a second signal that results in a caspase 1 mediated cleavage of pro- IL1\u03b2 to release the active molecule 55<\/sup>.<\/p>\n

Pretreatment with studied extracts decreased serum IL1 \u03b2 and TNF-\u03b1 in rats subjected to paracetamol hepatotoxicity. It was suggested that the two extracts have inhibitory effect on NF-kB\/Rel activity in rat serum.56<\/sup><\/p>\n

In summary, our present study demonstrated that S. monoica <\/em>and S. peruisma<\/em> possessed a protective action against paracetamol-induced liver injury. The underlying mechanisms of their hepatoprotective activity might be attributed to the presence of the amino acids, unsaturated fatty acids and phenolic compounds. These encouraging \ufb01ndings would be helpful for developing potential hepatoprotective agents for remedying APAP-induced liver injury.<\/p>\n
