[Survey on the Efficacy of Two Types of Medication Administration-assisting Food for Hospitalized Children].

The purpose of this study was to investigate the efficacy of two types of medication administration-assisting food. The subjects were 30 caregivers of children from one to eight years old hospitalized in the pediatrics unit of a university hospital, and 30 nurses caring for them. The caregivers gave medications to their children using two types of administration-assisting food, "chocolate" and "jelly".

Carbon tetrachloride-induced hepatic and renal damages in rat: inhibitory effects of cacao polyphenol.

Here, we investigated the protective effect of cacao polyphenol extract (CPE) on carbon tetrachloride (CCl4)-induced hepato-renal oxidative stress in rats. Rats were administered CPE for 7 days and then received intraperitoneal injection of CCl4. Two hours after injection, we found that CCl4 treatment significantly increased biochemical injury markers, lipid peroxides (phosphatidylcholine hydroperoxide (PCOOH) and malondialdehyde (MDA)) and decreased glutathione peroxidase activity in kidney rather than liver, suggesting that kidney is more vulnerable to oxidative stress under the present experimental conditions.

Anti-influenza virus effects of cocoa.

Background: Cocoa contains biologically active ingredients that have broad-spectrum antimicrobial activity, which includes an inhibitory effect on influenza virus infection.

Results: A cocoa extract (CE) was prepared by treating defatted cocoa powder with boiling water. The extract demonstrated dose-dependent inhibition of infection in Madin-Darby canine kidney (MDCK) cells infected with human influenza virus A (H1N1, H3N2), human influenza virus B and avian influenza viruses (H5N1, H5N9).

Theobromine enhances absorption of cacao polyphenol in rats.

Several concentrations of theobromine (TB) and (-)-epicatechin (EC) were coadministered to rats, and plasma EC and its metabolites were determined using ultra-high-performance liquid chromatography-tandem mass spectrometry. It has been demonstrated that TB increases the absorption of EC in a dose-dependent manner. Cocoa powder had a similar effect, and the mechanism involved is not thought to depend on tight junctions.

Oxidative stress during development of alcoholic fatty liver: therapeutic potential of cacao polyphenol.

The lipid and antioxidative/oxidative profiles of livers from rats fed an ethanol liquid diet for 8 weeks provided evidence for an involvement of oxidative stress (e.g., phospholipid peroxidation) in the development of alcoholic fatty liver (AFL), possibly in an early stage.

Extract of passion fruit (Passiflora edulis) seed containing high amounts of piceatannol inhibits melanogenesis and promotes collagen synthesis.

The effect of passion fruit, the fruit of Passiflora edulis , on melanin inhibition and collagen synthesis was studied using cultured human melanoma and fibroblast cells. Passion fruit was divided into three parts, rind (PF-R), pulp (PF-P), and seed (PF-S), and each part was extracted using 80% ethanol. The concentration of polyphenols was higher in PF-S than in PF-R or PF-P.

Antihypertensive effect of Benifuuki tea containing O-methylated EGCG.

Benifuuki is a tea cultivar with an antiallergic effect stronger than that of Yabukita tea, the most popular green tea cultivar consumed in Japan. The effective compound is (-)-epigallocatechin-3-O-(3-O-methyl)gallate (EGCG3''Me), an O-methylated derivative of EGCG. This study examined the antihypertensive effects of EGCG3''Me and Benifuuki tea.

Beneficial Effects of Cocoa in Perivascular Mato Cells of Cerebral Arterioles in SHR-SP (Izm) Rats.

As previously reported, the cerebral arterioles are surrounded by unique perivascular Mato cells. They contain many inclusion bodies rich in hydrolytic enzymes, and have strong uptake capacity. They are thus considered scavenger cells of vascular and neural tissues in steady-state.

Ingested cocoa can prevent high-fat diet-induced obesity by regulating the expression of genes for fatty acid metabolism.

Objective: We previously found that ingested cocoa decreased visceral adipose tissue weight in rat. To elucidate the molecular mechanisms of that effect, we carried out experiments aimed at analyzing biochemical parameters and gene expression profiles.

Methods: Rats were fed either of two high-fat diets, differing only in supplementation with real or mimetic cocoa.

Effects of an aqueous extract of cocoa on nitric oxide production of macrophages activated by lipopolysaccharide and interferon-gamma.

Objective: Macrophages are the primary targets of bacterial lipopolysaccharide (LPS). The effects of cocoa extract on production of nitric oxide (NO) by murine J774.1 macrophages activated by LPS and interferon-gamma (IFN-gamma) were examined.
