Natural Ingredients-Based Gummy Bear Composition Designed According to Texture Analysis and Sensory Evaluation In Vivo.

The increased interest in functional materials of natural origin has resulted in a higher market demand for preservative-free, "clean label", or natural ingredients-based products. The gummy bear food supplements are more acceptable to consumers and have fewer limitations compared to other dosage forms. The aim of our study was to produce natural ingredients-based gummy bear composition, and evaluate the influence of the selected ingredients on the product's textural properties, its acceptance in vivo, and the gummy bear's quality. The optimal base composition was determined using a surface response design: gelatin 4.3 g and agave syrup 6.3 g. The investigated sweeteners did not affect the textural properties (p > 0.05). However, further studies demonstrated that a 100% increase of agave results in up to 27% higher flexibility (p < 0.05). The addition of calcium and cholecalciferol reduced firmness by 59.59 ± 1.45% (p < 0.05). On the other hand, acai berry extract had no significant effect. The presence of calcium resulted in a decreased smell and taste; however, the data indicated that experimental texture analysis is a more accurate technique than in vivo evaluation. The acai berry extract did not improve all of the tested sensory properties. We can conclude that the suggested gummy bear base can be supplemented with various active ingredients and commercialized, though further studies are needed to investigate the other natural sources to mask the unpleasant taste of active ingredients and avoid water loss.

Effect of Acanthopanax senticosus on the accumulation of cadmium and on the immune response of spleen cells.

Exposure to cadmium (Cd) is known to alter immune responses. Acanthopanax senticosus (Rupr. et Maxim.) Harms (AS) extract, an antioxidant-containing complex of phenolic compounds, tetracyclic triterpenoids/steroids, and polysaccharides, is known to produce Cd mobilization and excretion in vivo. Building upon earlier findings, the aim of the study was to evaluate the effects of an AS extract on Cd accumulation and changes in the presence of splenic immune cells in hosts during a chronic metal exposure. Chronic Cd exposure of BALB/c mice was induced by providing them solutions containing different levels of CdCl2 (25 or 250 mg/L) in double-distilled water, with/without a concurrent presence of AS root extract (approximately 151 g material/L), for 8 wk. At the study end, Cd levels in spleen were measured. Levels of key splenic immune cells, including macrophages, T-lymphocytes, and B-lymphocytes, were determined by immunohistochemistry using, respectively, CD68, CD3, and CD20 antibodies. The results indicated that chronic consumption of AS extract in the presence of the high dose of CdCl2 led to a significant decrease in Cd levels in mouse spleen. The effects of AS on the lower CdCl2 dose were less apparent. In addition, the presence of AS and Cd increased the amount of macrophages and both B and T lymphocytes in mouse spleen relative to concentrations that were lowered as a result of chronic metal only intake.

Estimation of the combined effect of Eleutherococcus senticosus extract and cadmium on liver cells.

Cadmium (Cd) is an important industrial pollutant, even though its mechanism of toxicity has not been completely clarified. Cd(2+) is toxic to a wide range of organs and tissues. Liver and kidneys are the primary target organs of cadmium toxicity. Cd(2+) induces apoptosis and causes necrotic cell death in certain pathophysiological situations. Eleutherococcus senticosus (Rupr. et Maxim.) Maxim. has many beneficial features. It supports the organism's stress response, immune system, and endocrine system, including the adrenal glands, spleen, and thymus gland. The aim of our study was to investigate the effects of the Eleutherococcus senticosus (ES) liquid extract on the accumulation of Cd(2+) in liver and on the mitotic and apoptotic activity of liver cells after chronic intoxication by Cd(2+). Experiments were carried out on white laboratory mice. Laboratory mice were given to drink solutions of different Cd(2+) and ES concentrations for 8 weeks. Cd(2+) concentration in mouse liver was detected using atomic absorption spectroscopy. Mitotic and apoptotic activity of liver cells was expressed as an estimated number of mitotic and apoptotic cells in randomly selected reference areas in a histological slide. ES combined with CdCl(2) leads to a significant decrease of cadmium concentration in the blood and liver of experimental mice. ES decreased the cadmium-induced mitotic and apoptotic activity of liver cells.

Assessment of the effect of Echinacea purpurea (L.) Moench on apoptotic and mitotic activity of liver cells during intoxication by cadmium.

Cadmium (Cd(2+)) is an important industrial pollutant, although its mechanism of toxicity has not been completely clarified. Cd(2+) is toxic to a wide range of organs and tissues, however, the primary target organs of Cd(2+) toxicity are the liver and kidney. Echinacea purpurea stimulating one or another tread of the immune system stimulates the expression of immunoglobulins and interferons. The experiments were performed on white laboratory mice using intraperitoneal (i.p.) injections 0.05 LD(50) amount of CdCl(2) solution. Two groups of mice were injected by Echinacea purpurea liquid extract: one 0.05 LD(50) and the other 0.1 LD(50). In this article, the Cd(2+) distribution in internal organs, its effect on the mitotic and apoptotic activity of liver cells, as well as effects of Echinacea purpurea liquid extract on Cd(2+)-induced changes in mice were investigated. Cd(2+) concentration in mice blood, liver, and kidney was detected by atomic absorption spectroscopy. Long-term injections of extract of Echinacea purpurea combined with Cd(2+)Cl(2) leads to the significant increase of Cd(2+) concentration in blood and investigated organs of experimental mice. Mitotic and apoptotic activity of liver cells was expressed as the estimated number of mitotic and apoptotic liver cells in randomly selected reference areas in histological slide. Echinacea purpurea decreases the mitotic activity of liver cells induced by Cd(2+) and increases apoptotic activity of the liver cells.

Influence of Echinacea purpurea (L.) Moench extract on the toxicity of cadmium.

Echinacea purpurea (L.) Moench (EP) has many beneficial features, especially strengthening the immune system. Cadmium (Cd) is a ubiquitous metal and cumulative poison that may cause liver and kidney damage and the formation of neoplasia. In this article, the changes in organs and metabolism, the accumulation of various levels of Cd in tissues, and the effects of EP liquid extract on Cd-induced changes in mice were investigated. Experiments were carried out on the white laboratory mice. Solution of different Cd and EP concentrations were given to drink and experiments were performed. The concentration of Cd in mice blood, liver, kidneys, heart, spleen, skeletal muscle was determined using an electrothermal graphite furnace atomic absorption spectrophotometer Perkin-Elmer/Zeeman 3030. Long time per os of extract of EP combined with Cd leads to a significant increase of Cd concentration in blood and investigated organs of experiment mice.

UNLABELLED: Heavy metals (lead, cadmium) are possible dashes which quantity is defined by the limiting acceptable contents. Different drugs preparations: infusions, decoctions, tinctures, extracts, etc. are produced using medicinal plants. The objective of this research was to study the impurities of heavy metals (lead, cadmium) in medicinal plants and some drug preparations. MATERIALS AND METHODS: We investigated liquid extracts of fruits Crataegus monogyna Jacq. and herbs of Echinacea purpurea Moench., tinctures--of herbs Leonurus cardiaca L. The raw materials were imported from Poland. Investigations were carried out in cooperation with the Laboratory of Antropogenic Factors of the Institute for Biomedical Research. Amounts of lead and cadmium were established after "dry" mineralisation using "Perkin-Elmer Zeeman/3030" model electrothermic atomic absorption spectrophotometer (ETG AAS/Zeeman). It was established that lead is absorbed most efficiently after estimation of absorption capacity of cellular fibers. About 10.73% of lead crosses tinctures and extracts, better cadmium--49.63%. Herbs of Leonurus cardiaca L. are the best in holding back lead and cadmium. About 14.5% of lead and cadmium crosses the tincture of herbs Leonurus cardiaca L. We estimated the factors of heavy metals (lead, cadmium) in the liquid extracts of Crataegus monogyna Jacq. and Echinacea purpurea Moench., tincture of Leonurus cardiaca L. after investigations of heavy metals (lead, cadmium) in drugs and preparations of it. The amounts of heavy metals (lead, cadmium) don't exceed the allowable norms in fruits of Crataegus monogyna Jacq., herbs of Leonurus cardiaca L. and Echinacea purpurea Moench. after estimation of lead and cadmium extraction factors, the maximum of acceptable daily intake and the quantity of drugs consumption in day.

[Importance of biologically active components and plants in the prevention of complications of diabetes mellitus]. / Biologiskai veikliuju junginiu ir augalu reiksme cukrinio diabeto komplikaciju prevencijai.

Diabetes complications, especially late (chronic) ones, are the main reasons of invalidity and early mortality. The most threatening diabetes complications are vascular and metabolic complications (diabetic neuropathy, angiopathy, cataract, glaucoma, optic neuropathy, retinopathy, diabetic nephropathy). Good diabetes control is very important, because in early stages these changes are reversible. In order to decrease the number of diabetes complications and to postpone their development, the use of biologic active components and plants is recommended. The most important biologic active substances for this purpose are vitamins and minerals, proteins, polysaccharides, lectins, saponins and flavonoids. According the scientific data, the mostly used plants are: Ginkgo biloba, Allium sativum, Silybum marianum, Panax Ginseng, Carica papaya, Vaccinium myrtillus, Phaseolus vulgaris. Some of them are proposed for treatment of symptoms related to venous and lymphatic vessel insufficiency, for the prophylaxis and treatment of liver damage caused by metabolic toxins, in chronic degenerative liver conditions, for the therapy of digestive disorders, to increase in the unspecific way the resistance of the organism to various environmental influences, and to stabilize membranes through antioxidant and radical scavenging actions.
