  • In order to search for potential antidotes for T-2 toxin poisoning, seven Chinese herbal drug extracts and five natural constituents were tested on mice intoxicated with T-2 toxin. When extracts of Panax ginseng and Atractylodes japonica (500 mg/kg) were administered p.o. once 3 hrs before and once 1 hr after T-2 toxin treatment, a 30% complete survival rate was noted. In case of Paeonia albiflora var. typica, a 30% complete survival rate was also produced at a dose of 250 mg/kg. Other extracts, Glycyrrhiza uralensis, Scutellaria baicalensis, Rehmannia glutinosa and Plantago asiatica exhibited no significant protection from the T-2 toxin poisoning. A nucleoside, thymidine showed protective activity against T-2 toxin toxicity and it produced a 40% complete survival rate when administered i.p. once 0.5 hr after T-2 toxin treatment. Other natural constituents, aucubin, vitamin C and E, and lipoic acid did not show any significant protective activities.

  • Vegetarians have claimed and actively promoted the advantages of plant-based alternative milks as the best option for human nutrition and health, compared to the natural dairy milk. However, numerous scientific evidences and reports have demonstrated that the natural milk possesses more beneficial nutrients and bioactive components than artificially manufactured plant-derived milks. The biochemical and nutritional advantages and functionalities of natural dairy milk cannot be replaced by man-made or crafted plant-based beverage products. On the other hand, the tremendous increase in production and consumption of the plant-based alternative milks in recent years has led a serious business downturn in traditional roles and stability of the dairy industry, especially in the major dairy producing Western countries. Although plant-based milk alternatives may have some benefits on nutrition and health of certain consumers, the plant-derived alternative milks may not overshadow the true values of natural milk. Milk is not a high fat and high cholesterol food as animal meat products. Unlike plant-based alternative milks, natural milk contains many bioactive as well as antiappetizing peptides, which can reduce body weight. It has proven that taking low-fat, cultured and lactase treated milk and dairy products with other diversified nutritionally balanced diets have been shown to be healthier dietary option than plant-based milk/foods alone.

  • The diet plays a fundamental role in the formation of the gut microbiota, determining the interrelationship between the gut microbiota and the host. The current study investigated the effect of Chlorella vulgaris on the gut microbiota by using simulated in vitro digestion and colonic fermentation. Bioaccessibility was measured after in vitro digestion, and SCFAs and microbial profiling were analyzed after colonic fermentation. The bioaccessibility of C. vulgaris was 0.24 g/g. The three major SCFAs (acetate, propionate, and butyrate) increased significantly when compared to the control group. In microbial profiling analysis, microorganisms such as Faecalibacterium, Dialister, Megasphaera, Dorea, Odoribacter, Roseburia, Bifidobacterium, Butyricmonas, and Veillonella were high in C. vulgaris group. Among them, Faecalibacterium, Dialister, Megasphaera, Roseburia, and Veillonella were thought to be closely associated with the increased level of SCFAs. Finally, it can be expected to help improve gut microbiota and health through ingestion of C. vulgaris. However, further studies are vital to confirm the changes in the gut microbiota in in vivo, when C. vulgaris is ingested.

  • Cordycepin, a nucleoside derivative, was extracted from $Cordyceps$ $sinensis$, and then proved to be a bioactive compound present in traditional Chinese medicine Cordyceps. Early investigations revealed cordycepin possessed anti-microbial activity mainly by inhibiting nucleic acid synthesis. Although cordycepin is not used as antibacterial agents in clinic, its other pharmacological effects and possible mechanisms have gradually been deeply studied. This review serves to summarize the research progress of cordycepin.

  • Fucoidan은 갈조류의 세포벽에 존재하는 황산화 다당류이다. 본 연구에서는 자외선 B를 인체각질형성세포에 조사하여 matrix metalloproteinase-1 (MMP-1)을 발현 시킨 후 Fucus evanescens fucoidan이 MMP-1 promoter, mRNA, 단백 발현과 mitogen-activated protein kinases (MAPKs)의 인산화에 미치는 영향을 확인하고자 하였다. 자외선 B에 의해 생성된 MMP-1의 promoter activity와 mRNA, 단백 발현은 fucoidan $10\;{\mu}g/ml$$100\;{\mu}g/ml$를 투여하였을 때 fucoidan을 투여하지 않고 자외선만 조사한 군에 비하여 유의하게 억제되었다. 그리고 F. evanescens fucoidan은 extracellular signal regulated kinase (ERK)의 활성은 현저히 억제시켰으나 c-JUN N-terminal kinase (JNK)와 p38의 활성에 미치는 영향은 약하였다. 따라서 이 연구결과들은 F. evanescens fucoidan이 피부 광노화의 예방과 치료에 도움이 될 가능성을 확인할 수 있었다.

  • In the biological world, there are a number of ecological fights for survival between each organism such as plants, animals and microorganism In such events, an organism can use its natural bioactive products as defence agent against other organisms. Furthermore, natural bioactive products can be utilized for medicine or functional food. Recently, we investigate the effect of Monascus pigment extracted from a fungus, Monascus anke, on the alcohol metabolism and blood lipid profile. In the present study, it is observed that Monascus pigment supplemented dietary may have a hepatoprotective effect on rat's liver damage induced with $CCl_4$ . By treatment with $CCl_4$(3 times, I.P), liver damage was reduced more in the rats fed 2% Monascus pigment extract supplemented diet than those fed standard diet, based on the serum levels of alanine aminotransferase, microsomal glucose-6-phosphatse activity and hepaic malondialdehyde content. On the other hand, oxygen free radical generating enzymes, hepatic P-450 dependent aniline hydroxylase, xanthine oxidase, and oxygen free radical scavenging enzymes, hepatic glutathione S-transferase, catalase, superoxide dismutase activities were generally higher both in $CCl_4$ treated group and control fed 2% Monascus pigment extract supplemented diet than those fed standard diet. In conclusion, the rats fed 2% Monascus pigment extract supplemented diet showed more reduced liver damage than those fed standard diet, which may be due to the acceleration of oxygen free radical metabolism.

  • The use of medicinal food, food supplements and nutraceuticals is steadily increasing worldwide. These products are derived from a variety of sources of ethnic traditions and new research findings. They are being utilised in a diverse range of preventive and therapeutic situations. Because of this increased interest there is greater use of multiple natural products simultaneously. The use of combinations needs to be treated with circumspection. Mixing may have no unexpected consequences or it may have rather unanticipated beneficial outcomes. Just as likely are deleterious effects from combining the intake of natural products. Recent research has been quite useful in the characterisation of the consequences of some of these combinations and examples will be presented.

  • Processed meat products play a vital role in our daily dietary intake due to their rich protein content and the inherent convenience they offer. However, they often contain synthetic additives and ingredients that may pose health risks when taken excessively. This review explores strategies to improve meat product quality, focusing on three key approaches: substituting synthetic additives, reducing the ingredients potentially harmful when overconsumed like salt and animal fat, and boosting nutritional value. To replace synthetic additives, natural sources like celery and beet powders, as well as atmospheric cold plasma treatment, have been considered. However, for phosphates, the use of organic alternatives is limited due to the low phosphate content in natural substances. Thus, dietary fiber has been used to replicate phosphate functions by enhancing water retention and emulsion stability in meat products. Reducing the excessive salt and animal fat has garnered attention. Plant polysaccharides interact with water, fat, and proteins, improving gel formation and water retention, and enabling the development of low-salt and low-fat products. Replacing saturated fats with vegetable oils is also an option, but it requires techniques like Pickering emulsion or encapsulation to maintain product quality. These strategies aim to reduce or replace synthetic additives and ingredients that can potentially harm health. Dietary fiber offers numerous health benefits, including gut health improvement, calorie reduction, and blood glucose and lipid level regulation. Natural plant extracts not only enhance oxidative stability but also reduce potential carcinogens as antioxidants. Controlling protein and lipid bioavailability is also considered, especially for specific consumer groups like infants, the elderly, and individuals engaged in physical training with dietary management. Future research should explore the full potential of dietary fiber, encompassing synthetic additive substitution, salt and animal fat reduction, and nutritional enhancement. Additionally, optimal sources and dosages of polysaccharides should be determined, considering their distinct properties in interactions with water, proteins, and fats. This holistic approach holds promise for improving meat product quality with minimal processing.
