Abstract
Abstract
Background
Drug-induced hepatotoxicity is one of the most important causes of liver dysfunction. Acetaminophen (paracetamol) an analgesic-antipyretic drug is generally considered safe but its overdose may cause liver toxicity. Marine macro-algae (seaweeds) especially brown seaweeds possess unique biological activities including hepatoprotective potential. The current study focused on the hepatoprotective effect of different solvent fractions of Sargassum ilicifolium and characterization of its n-hexane soluble fraction.
Methods
The ethanol extract (20 g) of S. ilicifolium was mixed with solvents of increasing polarity, starting with n-hexane followed by chloroform and methanol. All three (n-hexane, chloroform and methanol) soluble fractions were administered to the rats at dose of 150 mg/kg, b.w. Intraperitoneal administration of acetaminophen (600 mg/kg b.w.) to rats was used to cause liver injury. The hepatic damage was evaluated by liver markers enzymes; aspartate aminotransferases (AST), alanine aminotransferases (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), bilirubin along with other metabolites i.e., triglycerides, cholesterol, urea, glucose and creatinine. Lipid peroxidation and glutathione and were estimated in liver tissue. n-Hexane fraction was subjected to GC-MS analysis in order to identify potent compounds.
Results
The oral administration of n-hexane and methanol soluble fractions reduced the acetaminophen-augmented liver marker enzymes ALT, AST, ALP, LDH, along with bilirubin, urea, creatinine, glucose and triglycerides. The n-hexane and methanol soluble fractions also improved hepatic antioxidant level via enhancing hepatic glutathione and reversing lipid peroxidation. GC-MS spectroscopy of n-hexane fraction of S. ilicifolium revealed the presence of some new compounds. Among them, fatty acids were found to be in highest concentration followed by halogenated hydrocarbons, benzene derivatives, and sterols. Fatty acid in seaweed may be one of the factors for hepatoprotection from drug-induced hepatotoxicity.
Conclusion
From the results, it is evident that n-hexane and methanol soluble fractions of S. ilicifolium have the ability to protect the liver against toxicity, which is comparable with silymarin used as a standard drug. Sargassum ilicifolium contains bioactive compounds with pharmaceutical importance.

Abstract
The Styela clava tunic (SCT) is known as a good raw material for preparing anti-inflammatory compounds, wound healing films, guided bone regeneration, and food additives. To investigate whether ethanol extracts of the SCT (EtSCT) could protect against hepatic injury induced by carbon tetrachloride (CCl4) in ICR mice, alterations in serum biochemical indicators, histopathology, hepatic apoptosis, inflammation, and fibrosis were observed in ICR mice pretreated with EtSCT for 5 days before CCl4 injection. EtSCT contained 15.6 mg/g of flavonoid and 37.5 mg/g phenolic contents with high 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (93.3%) and metal chelation activity (46.5%). The EtSCT+CCl4-treated groups showed decreased levels of ALT, LDH, and AST, indicating toxicity and a necrotic area in the liver, while the level of ALP remained constant. The formation of active caspase-3 and enhancement of Bax/Bcl-2 expression was effectively inhibited in the EtSCT+CCl4-treated groups. Furthermore, the levels of pro- and anti-inflammatory cytokines and the phosphorylation of p38 in the TNF-α downstream signaling pathway rapidly recovered in the EtSCT+CCl4-treated groups. The EtSCT+CCl4-treated groups showed a significant decrease in hepatic fibrosis markers including collagen accumulation, MMP-2 expression, TGF-β1 concentration, and phosphorylation of Smad2/3. Moreover, a significant decline in malondialdehyde (MDA) concentration and enhancement of superoxide dismutase (SOD) expression were observed in the EtSCT+CCl4-treated groups. Taken together, these results indicate that EtSCT can protect against hepatic injury induced by CCl4-derived reactive intermediates through the suppression of hepatic apoptosis, inflammation, and fibrosis.

Abstract
The cancer chemopreventive activity of the polysaccharide extracts (E1-E4) of Sargassum asperifolium, a brown alga in Red Sea shores in Egypt, was investigated. Tumour anti-initiation activity (the modulation of carcinogen metabolism) indicated that E3 and E4 were potent anti-initiators by inhibiting the carcinogen activator cytochrome P450-1A, and enhancing carcinogen detoxification enzymes glutathione-S-transferase. Only E4 significantly enhanced quinone reductase activity. All polysaccharide extracts possessed anti-promotion property by their anti-inflammatory activity. E3 and E4 dramatically induced the growth of spleen macrophages. E2, E3 and E4 significantly inhibited nitric oxide generation from lipopolysaccharide (LPS)-stimulated spleen macrophages, while E1, E3 and E4 led to significant inhibition of LPS-induced tumour necrosis factor-α. The extracts E1, E2 and E4 showed cytotoxicity against HepG2 cells, where E2 and E4 induced cell death due to apoptosis. In conclusion, E3 and E4 are promising cancer chemopreventive extracts, since they had tumour anti-initiating activity via their protective modulation of carcinogen metabolism.

Abstract
Abstract Context: Ulva lactuca Linnaeus (Chlorophyceae), a commonly distributed seaweed, is rich in polysaccharide but has not been studied extensively. Objective: The present study investigated the effects of crude fraction of Ulva lactuca polysaccharide (ULP) on d-galactosamine (d-Gal)-induced DNA damage, hepatic oxidative stress, and necrosis in rats. Materials and methods: The rats were treated with ULP (100 mg/kg, orally) for 4 weeks before a single intraperitoneal injection of d-Gal (500 mg/kg). In addition to liver cell necrosis and DNA damage, antioxidant parameters, such as lipid peroxide (LPO), superoxide dismutase, and catalase, and histopathology of liver tissue were evaluated. Results: ULP pre-treatment significantly attenuated a d-Gal-induced decrease in DNA and RNA levels (3.67 ± 0.38) and (5.42 ± 0.46), respectively. Comet tail length and acridine staining confirmed the number of cells undergoing necrosis were relatively lower in ULP treated rats (30 µm and 8-10% of counted cells) compared to rats treated with d-Gal (60 µm and 16% of counted cells). Biochemical (LPO, SOD and CAT) and histological evaluation (p < 0.01) confirmed the anti-hepatotoxic and antioxidant property of crude polysaccharide against d-Gal-induced elevation of LPO and infiltration of inflammatory cells into liver tissue. Discussion and conclusion: Although our previous studies have reported on the protective role of ULP against liver toxicity, our present findings show that ULP improved the hepatic antioxidant defense system against d-Gal-induced DNA damage and necrosis in rats.

Preliminary investigation of a highly sulfated galactofucan fraction isolated from the brown alga Sargassum polycystum. Carbohydr Res 2013; 377:48-57.

Abstract
A fucoidan preparation was isolated from the brown alga Sargassum polycystum (Fucales, Sargassaceae). The preparation was fractionated by anion-exchange chromatography, and two highly sulfated fractions F3 and F4 were obtained. The fractions were quite similar in composition, but different in chemical structure. F4 was analyzed by chemical methods, including desulfation, methylation, Smith degradation, and partial acid hydrolysis with mass-spectrometric monitoring, as well as by NMR spectroscopy. Several 2D NMR procedures, including HMQC-TOCSY and HMQC-NOESY, were used to obtain reliable structural information from the complex spectra. Molecules of F4 were shown to contain a backbone built up mainly of 3-linked α-L-fucopyranose 4-sulfate residues, as in many other fucoidans, but rather short sequences of these residues are interspersed by single 2-linked α-D-galactopyranose residues also sulfated at position 4. This rather unusual structural feature should have a great influence on the conformation of the polymeric molecule and may be important for biological activity of the polysaccharide. Hence, F4 is an example of a new sulfated galactofucan isolated from the brown alga. According to the data obtained, the distribution of galactose residues along the polysaccharide backbone seems to be not strictly regular, but the definitive sequence of monomers in the polymeric molecules awaits additional investigation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE For nearly 2000 years Sargassum spp., a brown seaweed, has been used in Traditional Chinese Medicine (TCM) to treat a variety of diseases including thyroid disease (e.g. goitre). AIMS OF THE REVIEW To assess the scientific evidence for therapeutic claims made for Sargassum spp. in TCM and to identify future research needs. BACKGROUND AND METHODS A systematic search for the use of Sargassum in classical TCM books was conducted and linked to a search for modern phytochemical and pharmacological data on Sargassum spp. retrieved from PubMed, Web of Knowledge, SciFinder Scholar and CNKI (in Chinese). RESULTS AND DISCUSSION The therapeutic effects of Sargassum spp. are scientifically plausible and may be explained partially by key in vivo and in vitro pharmacological activities of Sargassum, such as anticancer, anti-inflammatory, antibacterial and antiviral activities. Although the mechanism of actions is still not clear, the pharmacological activities could be mainly attributed to the major biologically active metabolites, meroterpenoids, phlorotanins and fucoidans. The contribution of iodine in Sargassum for treating thyroid related diseases seem to have been over estimated. CONCLUSIONS The bioactive compounds in Sargassum spp. appear to play a role as immunomodulators and could be useful in the treatment of thyroid related diseases such as Hashimoto's thyroiditis. Further research is required to determine both the preventative and therapeutic role of Sargassum spp. in thyroid health.

Abstract
Polysaccharides of edible algae attracted extensive interest due to their numerous biological activities. Sargassum latifolium (Turner) C. Agardh, belongs to Sargassaceae, is a brown algae in red sea shores in Egypt. This work is a novel attempt to explore the cancer chemopreventive activity of different fractions of water-soluble polysaccharide extract derived from S. latifolium. Estimation of cancer chemopreventive activity, specifically anti-initiation, including the modulation of carcinogen metabolism and the antioxidant capacity, revealed that E1 and E4 were potent anti-initiators, where they lead not only to an inhibition in the carcinogen activator cytochrome P450 1A (IC50 2.54 and 10.30 microg/ml, respectively), but also to an induction in the carcinogen detoxification enzymes glutathione-S-transferases (144% and 225% of the control, respectively). E1 and E4 inhibited 59% and 63% of the induced-DNA damage, as measured by comet assay. Similarly both E1 and E4 possessed potential anti-promoting properties as indicated by their anti-inflammatory activity. E1 and E4 enhanced the macrophage proliferation; however they dramatically inhibited the stimulated NO (30.7% and 59.3%), TNF-alpha (38.2% and 54.9) and COX-2 (20% and 18%), respectively. E3 showed a selective cytotoxicity against lymphoblastic leukemia (1301 cells), while other fraction extracts had no cytotoxic effect against all tested cell lines. E3 led to a major disturbance in cell cycle including arrest in both S-phases in 1301 cells. This disturbance was associated with an induced-cell death due to apoptosis, but not necrosis. In conclusion, E1 and E4 are promising cancer chemopreventive fractions, since they had tumor anti- initiating activity via their protective modulation of carcinogen metabolism, and tumor anti-promoting activity via their anti-inflammatory activity, while E3 can be considered as a promising anti-cancer agent against leukemia.
