The role of oxidative stress as a major cause of tissue injury has been suggested and it has been demonstrated that changes in the oxidant and antioxidant mechanisms contribute largely to hepatic necrosis in these situations. However, the increased intake of foods rich in antioxidants could help minimize this damage. The aim of this present work was to evaluate the effect of coffee beverage on lipid peroxidation and markers of liver function in rats with cirrhosis induced by carbon tetrachloride. Our results demonstrated that CCl 4 is effective in the induction of liver cirrhosis and the compounds presents in coffee drink are able to decrease the hepatic lipid peroxidation induced by carbon tetrachloride, making a significant hepatoprotective effect in accordance with the liver function tests.

Marine algae are found in abundance along the shore of Goa, and have not been utilized. This is a report of hemagglutinins isolated from these marine algae. Phosphate-buffered saline extracts from six marine algae were tested for their agglutination activity using human blood cells by a slide assay. The extracts from four species revealed hemagglutinating activity against the tested human erythrocytes. However, the results obtained did not indicate specificity toward any particular human blood group. Further, one extract that showed good agglutination was processed for ammonium sulfate precipitation. The precipitated product was assayed for hemagglutination titer and sugar-binding specificity. The hemagglutination activity of the Sargassum cinnerium extract was observed to be specifically inhibited by one of the tested sugars. Because agglutination is a characteristic of “lectins,” the results obtained are indicative of these marine algae being a rich source of products/novel substances having biotechnological applications.

Phytoconstituents, despite having excellent bioactivity in vitro, demonstrate less or no in vivo actions due to their poor lipid solubility or improper molecular size or both, resulting in poor absorption and poor bioavailability. Lipid solubility and molecular size are the major limiting factors for molecules to pass the biological membrane and to be absorbed systematically following oral or topical administration. Some phytoconstituents are destroyed in the gastric environment when taken orally. The term “phyto” means plant, while “some” means cell-like. Therefore, phytosome is a “phytophospholipid complex” resembling a small cell. Phytosomes are produced by a patented process whereby standardized plant extracts or their constituents are bound to phospholipids, mainly phosphatidylcholine, producing a lipid-compatible molecular complex. Phytosomes exhibit a better pharmacokinetic and pharmacodynamic profile than conventional herbal extracts. The phytosome technology markedly enhances the bioavailability of phytomedicine and has effectively enhanced the bioavailability of many popular herbal extracts, including Milk thistle, Ginkgo biloba, Grape seed, Green tea, Hawthorn, Ginseng etc., and can be developed for various therapeutic uses or dietary supplements.

Wound, a clinical entity, is as old as mankind and often possesses problems in clinical practice. Naturally, the investigative curiosity to promote healing continues since ages. A lot of research has been envisaged to develop better healing agents and it has been a challenging task to generate them and keep pace with the problems encountered. Several drugs of plant, mineral, and animal origin are described in the Ayurveda for their wound healing properties. Most of these drugs are derived from plants. Some of these plants have been screened scientifically for the evaluation of their wound healing activity in different pharmacological models. Some Ayurvedic medicinal plants, namely Argemone mexicana, Boerhaavia diffusa, Catharanthus roseas, Diospyros cardifolia, Eclipta alba, Ficus religiosa, Hypericum perforatum, Lawsonia inermis, Merremia tridentate, and Swertia chirata, were found to be effective in experimental models. The rapidity of wound healing depends, to a considerable extent, on the contraction that begins a few days after injury and continues for several weeks. In the present review, attempts are made to understand various aspects of wound healing in terms of percentage closure of wound, period of complete epithelialization, tensile strength, histopathology, and weight of granuloma in different wound models.

Peptic ulcers are a broad term that includes ulcers of digestive tract in the stomach or the duodenum. The formation of peptic ulcers depends on the presence of acid and peptic activity in gastric juice plus a breakdown in mucosal defenses. There are two major factors that can disrupt the mucosal resistance to injury: non-steroidal antiinflammatory drugs (NSAIDs) example, aspirin and Helicobacter pylori infection. Numerous natural products have been evaluated as therapeutics for the treatment of a variety of diseases, including peptic ulcer. There has been considerable pharmacological investigation into the antiulcer activity of some compounds. In this work, we shall review the literature on different medicinal plant and alkaloids with antiulcer activity. This article reviews the antiacid/anti-peptic, gastroprotective and/or antiulcer properties of the most commonly employed herbal medicines and their identified active constituents. The experimental parameters used for antiulcer activity were cold restraint stress-induced ulcer model, Diclofenac-induced ulcer model in rats, (HCl-ethanol)-induced ulcer in mice and water immersion stress-induced ulcer in rats. The ideal aims of treatment of peptic ulcer disease are to relieve pain, heal the ulcer and delay ulcer recurrence. About 70% of patients with peptic ulcer disease are infected by Helicobacter pylori and eradication of this microorganism seems to be curative for this disease. This article reviews drugs derived from medicinal plant more commonly used in the world for peptic ulcer and, if reported, the antiulcer activity. This article will be concerned only with the antiulcer and gastro-protective effects.
