Beneficial effect of a symbiotic preparation with S. boulardii lysate in mild stress-induced gut hyper-permeability.

Increased intestinal permeability has been advocated as one of the likely causes of various pathologies, such as allergies and metabolic or even cardiovascular disturbances. Thus, the aim of the present study was to test a symbiotic preparation containing microbial lysates (KC-1317, Named, Italy) against stress-induced derangement of gut mucosa permeability. Sprague Dawley rats were allocated into control (n=20) and stress (n=20) group.

Improving sperm quality and spermatogenesis through a bioactive marine compound: an experimental study.

Dietary lipids may affect sperm membrane structure, fluidity and its susceptibility to oxidative phenomena which may lead to altered sperm viability and proper binding to eggs. Given the recently demonstrated beneficial effects of fish oil diets on turkey fertility and embryo viability, the aim of this study was to test a caviar-derived marine product on spermatogenesis and sperm quality. Sixty mice were divided into four different groups and fed for 3 weeks with normal chow (group A), added with LD-1227 at the dosage of either 5 mg/day (B1) or 10 mg/day (B2) while Group C received standard chow added with 10 mg of a DHA-rich mixture.

Inhibiting insulin resistance mechanisms by DTS phytocompound: an experimental study on metabolic syndrome-prone adipocytes.

The present study was designed to determine whether DTS a phytocompound endowed with antioxidant properties, could beneficially modulate nitric oxide (NO) production stimulated by lipopolysaccharide (LPS) and tumor necrosis factor-alpha (TNF-alpha) in adipocytes. Combined stimulation (CS-treatment) exerted by using 5 microg/ml of LPS together with 100 ng/ml of TNF-alpha significantly enhanced NO production in 3T3-L1 adipocytes. Preincubation of the adipocytes with DTS (10-30 mM) inhibited such phenomenon in a dose-dependent fashion.

Beneficial modification of functional renal parameters in 5/6 nephrectomized rats by nutraceutical. In view of a kidney-protective intervention.

The objective of this study is to ascertain the potential beneficial effects of a novel phytoterapeutic formula (DTS, Kyotsu Jigyo, Japan) on renal function and morphological structure in 5/6 nephrectomized rats. Male Spraque-Dawley rats, 240-280 g, were divided into sham control (Group A) and nephrectomized (Group B and Group C) groups. The 5/6 nephrectomy was performed by removal of the right kidney and 2/3 ligation of left renal artery.

Beneficial modulation from a high-purity caviar-derived homogenate on chronological skin aging.

This study tested the activity of LD-1227, which contains a caviar-derived homogenate added with coenzyme Q(10) (CoQ(10))-selenium component (CaviarLieri(®), Lab-Dom, Switzerland), in aged human skin and its potential role on skin mitochondria function. Human dermal fibroblasts were obtained from healthy donors over 70 years old and treated with LD-1227 for 72 hr. As compared to baseline, LD-1227 caused a robust (>67%) collagen type I synthesis (p<0.

A phytochemical approach to experimental metabolic syndrome-associated renal damage and oxidative stress.

The aim of this study was to evaluate the effect of DTS-phytocompound on oxidant-antioxidant balance and protein damage in the kidneys of rats administered high doses of fructose. Adult male Wistar rats were divided into four groups. Group A received a control diet, whereas groups B and C were fed a high-fructose diet (60 g/100 g), the latter with additional DTS (50 mg/kg per day) for 60 days.

Progression of atherosclerotic lesions in the arteries and related gene expression: protective effect of phytonutrients.

We investigated the effect of the phytocompound Denshici-to-Chiusei (DTS) on the atherogenesis in apolipoprotein E(-/-)/low-density lipoprotein receptor(-/-) (apoE(-/-)/LDL receptor(-/-)) mice (E0). E0 mice were fed for 16 weeks with: (1) placebo or (2) 25 mg or (3) 50 mg of DTS/day. Aortic lesions were reduced by 38% (p < 0.

Protective effect of a phytocompound on oxidative stress and DNA fragmentation against paracetamol-induced liver damage.

The hepatoprotective potential DTS (1.5 g/kg bw, Denshici-to-Chiusei, Kyotsu Jigyo, Tokyo, Japan) was evaluated against either toxic (1.5 g/kg bw) and sub-toxic (150 mg/kg bw) dosage of paracetamol-induced liver injury in Sprague-Dawley rat.

Effect of a phyto-compound on delayed gastric emptying in functional dyspepsia: a randomized-controlled study.

Objective: The aim of the present study was to assess the efficacy of a hydro-alcoholic solution of a phytocompound based on Gentianae, Cinchonae, Absinthii and Cinnamomi on gastric emptying in Helicobacter pylori-negative dyspeptic patients.

Methods: The study group consisted of 24 patients with a diagnosis of long-standing dismotility-like functional dyspepsia. All patients were devoid of any major past or ongoing disease and dyspepsia-associated diseases were excluded.

"Accelerating aging" chemotherapy on aged animals: protective effect from nutraceutical modulation.

The aim of this study was to test a novel phytocompound in an experimental model of antitumor-induced immunosuppression. Five groups of mice were considered: young (Y) and aged (A) that were given intraperitoneally 10 doses of cyclophosphamide (CPX, 25mg/kg/bw) or CPX plus (150 mg/kg/bw) of the nutraceutical DTS (Denshichi-Tochiu-Sen), and control. After sacrifice, macrophage chemotaxis and serum levels of IFN-gamma, IL-2, and GM-CSF were determined.

In vitro study on the mechanisms of action of a novel phytotherapeutic compound against human hepatoma cells.

HepG2 human hepatoma cells were incubated for 24 or 48 h with various concentrations of YHK solution. After 24 h incubation, cell proliferation and cytotoxicity were determined by 3-(4,5-dimethylthiazol-2- yl)-5-(3- carboxymethoxyphenyl)-2-(4-sulfophenyl)-2Htetrazolium (MTT) assay. Cytotoxicity or necrosis was expressed as lactate dehydrogenase (LDH) release.

Effect of a novel phyto-compound on mucosal candidiasis: further evidence from an ex vivo study.

Objective: To isolate, identify and determine the prevalence of yeasts in the oral cavity of individuals and to test the minimum inhibitory dilution (MID) of Kolorex against the yeasts isolated.

Methods: Twenty-nine individuals of both sexes aged on average 61.3 years were evaluated at the dental clinic in order to isolate and identify yeasts from their oral cavity, with and without lesions, and to determine the MID of the commercial phyto-product Kolorex against the strains isolated.

Effect of a prebiotic-enriched phytocompound in improving ovalbumin allergenicity.

Objective: The aim of the present study was to test a prebiotic-phytotherapic compound in an experimental model of oral allergenicity.

Methods: Antigen-specific immunoglobulin E (IgE) elevated mice were prepared by injecting them intraperitoneally with 10 microg of ovalbumin. Subsequently, the mice were exposed to ovalbumin solution intranasally and blood samples were obtained on weekly intervals for 4 weeks to measure serum-ovalbumin-specific IgE and total immunoglobulin G.
