Biological properties of mucus from land snails () and freshwater snails () and histochemical study of mucous cells in their foot.

Background: Mucus derived from many land snails has been extensively utilised in medicine and cosmetics, but some biological activities of the mucus need to be well documented. Nevertheless, most mucus is obtained from land snails, while mucus from freshwater snails has yet to be attended.

Methods: This study aims to determine and compare mucus's antioxidant and anti-inflammatory activities from the land snail and the freshwater snail .

Comparative histochemical study of the gastrointestinal tracts of the Nile tilapia (Oreochromis niloticus) and the hybrid catfish (Clarias batrachus x Clarias gariepinus).

Because of the wide variety of cells which are arrayed in the tissue of the gastrointestinal tracts of these two fish, basic histological examination is not appropriate to clarify the histological structure. But histochemical techniques can be applied to identify the chemical differences contained in the tissues. The present study aimed to compare the histochemical characteristics of the gastrointestinal tracts of adult fishes which consume different types of food: the Nile tilapia is herbivore and the hybrid catfish is carnivore.

Lethal and sublethal effects of a methomyl-based insecticide in .

The aim of this study was to investigate the lethal and sublethal toxicity of a methomyl-based insecticide in , as methomyl-based insecticides are applied in massive amounts and agrochemicals have effects on the decline in amphibian populations. To evaluate the toxic effects of methomyl from agricultural application, a methomyl-based insecticide containing 40% methomyl was selected. The median lethal concentration of 96 hours of methomyl exposure was 8.

Uvaria rufa Blume attenuates benign prostatic hyperplasia via inhibiting 5α-reductase and enhancing antioxidant status.

Ethnopharmacological Relevance: Traditional medicine has used Uvaria rufa Blume as an ethnomedicinal plant for treating fever, skin allergies, intestinal ulcers and prostate disorders including BPH. However, no scientific evidence supports the traditional use.

Aim Of The Study: This study aimed to evaluate the therapeutic potential of U.

Monascus purpureus-fermented Thai glutinous rice reduces blood and hepatic cholesterol and hepatic steatosis concentrations in diet-induced hypercholesterolemic rats.

Background: Red yeast rice (RYR) is a fermented product used as a food supplement to promote blood circulation and lower blood cholesterol levels in eastern Asia. Interestingly, monacolin K is the most active compound in RYR that proved to inhibit HMG-CoA reductase in the cholesterol biosynthesis pathway.

Methods: The hypocholesterolemic effects of oral administration of Thai RYR, produced by fermentation of Thai glutinous rice (Oryza sativa L.

Molecular analysis of echinostome metacercariae from their second intermediate host found in a localised geographic region reveals genetic heterogeneity and possible cryptic speciation.

Echinostome metacercariae are the infective stage for humans and animals. The identification of echinostomes has been based until recently on morphology but molecular techniques using sequences of ribosomal RNA and mitochondrial DNA have indicated major clades within the group. In this study we have used the ITS2 region of ribosomal RNA and the ND1 region of mitochondrial DNA to identify metacercariae from snails collected from eight well-separated sites from an area of 4000 km2 in Lamphun Province, Thailand.

Histopathological alterations of the gills, liver and kidneys in Anabas testudineus (Bloch) fish living in an unused lignite mine, Li District, Lamphun Province, Thailand.

The acidity of mine water generally makes it toxic to most organisms. The gills, kidneys and livers of Anabas testudineus Bloch fish inhabiting the acidic water (pH 2-4) of an unused lignite mine in Li District, Lamphun Province, Thailand were examined and compared to those of farmed fish. Tissue abnormalities were found in all investigated organs.

Haplorchis taichui: worm recovery rate and immune responses in infected rats (Rattus norvegicus).

Worm recovery rate, mucosal mast cells (MMCs), eosinophils and serum IgE concentration in rats were investigated after orally feeding 300 Haplorchis taichui metacercariae to male rats. The duodenal, jejunal and ileal tissue sections were stained with 1% alcian blue and 0.5% safranin-O for MMC count.

Effect of Kaempferia parviflora Wall. ex. Baker on sexual activity of male rats and its toxicity.

Kaempferia parviflora Wall. Ex. Baker (Krachaidum) has long been used among Thai men for sexual enhancement.

Safety evaluation of aqueous extracts from Aegle marmelos and Stevia rebaudiana on reproduction of female rats.

The purpose of this study was to evaluate the safety of a Thai medicinal plant, Aegle marmelos, and a non-caloric sweetener, Stevia rebaudiana, on the reproduction of female rats. Female rats were treated orally with aqueous extract of A. marmelos (6%) and S.

Chronological observations of intestinal histopathology in rats (Rattus norvegicus) infected with Centrocestus caninus.

Intestinal pathological enzyme activity changes were studied chronologically in rats after Centrocestus caninus infection. A single inoculation of 300 metacercariae isolated from the gills of goldfish (Carassius auratus), was orally administered to male rats (n = 15). Uninfected animals were used as controls (n = 5).

Mucosal mast cell responses in rats (Rattus norvegicus) experimentally infected with Centrocestus caninus.

Mucosal mast cell (MMC) responses and worm recovery rates in rats experimentally infected with Centrocestus caninus were investigated. Metacercariae of C. caninus, procured from goldfish, Carassius auratus, were orally administered to twenty-five male rats (300 metacercariae each rat).

Susceptibility of rodents to Stellantchasmus falcatus infection.

Two rodent hosts, rats (Rattus norvegicus) and mice (Mus musculus), were examined for their susceptibility to Stellantchasmus falcatus infection. The metacercariae were recovered from half-beaked fish, Dermogenus pusillus, collected from Hang Dong District, Chiang Mai Province. A single inoculation of three hundred metacercariae was orally conducted with male rats (n=15) and mice (n=15).
