ABSTRACT
We reported 2 cases of plantar keratosis (59 years of age, female/39 years of age, male) successfully improved by intake of hot water extract of Coix lacryma-jobi L. var. ma-yuen Stapf with Husks. Both subjects were administered coix seed extract containing food for 20 weeks. The lesions improved gradually after 12 weeks, and almost cured by 20 weeks of administration. Although the food seemed to be effective in these cases, further studies are needed to define the optimal dose and duration.
ABSTRACT
We evaluated the long-term safety of eight adult volunteers (male 7, female 1: average age 47.4 years) ingesting powdered foods containing Coix-seed Reactive Derivatives (CRD/2.2g/day or 4.4g/day) for 1 year 8 months to 5 years (average 2 years 9 months). Body weight, vital signs (blood pressure, pulse rate), peripheral blood test, blood biochemical test, etc. were observed. We also investigated the presence or absence of side effects. The results showed no notable changes in vital signs or blood test results. From the above, it was speculated that long-term intake of CRD would not pose a safety problem. We plan to continue the study by increasing the number of observation cases in the future.
ABSTRACT
Objective: We investigated the effects of Coix-seed Reactive Derivatives (CRD) on fibroblast proliferation and collagen production. Methods: Various concentrations of CRD (0.00001%, 0.0001%, 0.001%, 0.01%, 0.1%, 1%) were added to human fibroblasts, and changes in cell count and extracellular collagen production were measured. Results: Fibroblasts proliferated by the addition of CRD, peaked at about 1.7 times when the CRD concentration was 0.0001%, and then decreased as the addition concentration increased. On the other hand, the collagen concentration in the extracellular matrix of fibroblasts increased as the CRD addition concentration increased, and the collagen concentration increased sharply at 0.1% of CRD concentration or more. Conclusion: It was suggested that CRD has a function of increasing the proliferation of fibroblasts and collagen production.
ABSTRACT
In this report, we presented the case of a 33-year-old woman who developed excoriation of cuticle on both fingers for over several years. Coix-seed Reactive Derivatives(CRD) was administrated at a dose of 4.0g/day per day. The lesion cured markedly within 8 weeks. Although CRD intake seemed to be effective in this case, further studies are needed to confirmation the efficacy of this food.
ABSTRACT
In this report, we presented the case of a 45-year-old man who developed intractable eczema on the thumb-index interdigital fold for over 3 years. Coix-seed Reactive Derivatives(CRD) was administrated at a dose of 2.2g/day per day. The lesion cured markedly within 7 months. Although CRD intake seemed to be effective in this case, further studies are needed to define the optimal dose of this food.
ABSTRACT
To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 2 cases of plantar wart (case 1. 8 years of age, female/ case 2. 26 years of age, female) successfully cured by intake of CRD for several months. Although CRD intake seemed to be effective in these cases, further studies are needed to define the optimal dose and duration.
ABSTRACT
To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 3 cases of refractory atopic dermatitis(case 1. 25 years of age, male/ case 2. 40 years of age, female/ case 3. 5 years of age, male) successfully cured by intake of CRD. Although CRD intake seemed to be effective in all cases, further studies are needed to define the optimal dose and duration.
ABSTRACT
To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 2 cases of plantar keratosis (case 1. 34 years of age, female/ case 2. 29 years of age, female) successfully cured by intake of CRD for several months. Although CRD intake seemed to be effective in these cases, further studies are needed to define the optimal dose and duration.
ABSTRACT
We evaluated the effect of Coix-seed Reactive Derivatives (CRD) on cold sensitivity of female hands and feet. Ninety females were assigned randomly to 3 groups and CRD(2g/day, 4g/day or placebo) was administrated for 8weeks. Significant improvement of cold sensitivity was observed in both the 2g/day and 4g/day groups. It was speculated that a naringenin and a quercetin as active ingredients of adlay hull may play a critical role in ameliorating effect on blood flow.
ABSTRACT
To clarify the functions of Coix-seed Reactive Derivatives(CRD), we analyzed 13 kinds of phenolic compounds and coixol(an alkaloid) in CRD powder by using Liquid Chromatography/Mass Spectrometry(LC-MS).The following are the results: p -Coumaric acid 275.0 (μg/g), p -Hydroxybenzaldehyde 50.2 (μg/g), Caffeic acid 36.9 (μg/g), Protocatechuic acid 31.9 (μg/g), Ferulic acid 27.1 (μg/g), Quercetin 16.2 (μg/g), Syringaldehyde 12.1 (μg/g), Chlorogenic acid 11.3 (μg/g), Naringenin 11.1 (μg/g), Vanillin 9.2 (μg/g), trans -Coniferylaldehyde 9.1 (μg/g), Tricin 0.7 (μg/g), Luteolin 0.5 (μg/g) and Coixol(6-Methoxy-2-benzoxazolinone) 5.5 (μg/g). CRD is composed of many substances other than these phenoic compounds. Therefore, further studies are needed to understand the various clinical features associated with CRD intake.
ABSTRACT
To clarify the functions of Coix Reactive Derivatives(CRD), we observed 4 cases of refractory acne vulgaris (case 1. 20 years of age, male/ case 2. 46 years of age, female/ case 3. 20 years of age, male /case 4. 28 years of age, female) successfully cured by intake of CRD for several months. Although CRD intake seemed to be effective in all cases, further studies are needed to define the optimal dose and duration.
ABSTRACT
In this report, we presented the case of a 52-year-old woman who developed intractable nummular eczema of fingers for over 5 years. Coix-seed Reactive Derivatives(CRD) was administrated orally 2.2 g twice a day for 6 months. The lesions cured markedly within one month. Although CRD intake seemed to be effective in this case, further studies are needed to define the optimal dose of this food.
ABSTRACT
Friction melanosis is a cutaneous entity characterized by a brownish pigmentation distributed on the skin over bony regions of various sites including a trunk or the limbs, after the use, for many years, of a nylon towel or scrub brush to clean the skin. Moreover, repeated trauma due to friction of clothes on the skin over bony prominences are another factors characterizing its pathogenesis. In this report, we presented the case of a 58-year-old man who developed severe friction melanosis around both knees and lower extremities for about 20 years. Coix-seed Reactive Derivatives (CRD) was administrated orally 2.1g twice a day for 6 months. The lesions of pigmentation diminished markedly within 3 months. Further research is needed to define the optimal dose and duration of CRD intake against friction melanosis.
ABSTRACT
Ultraviolet (UV)-induced wrinkle and pigmentation are very common in clinical practice. In this report, we presented the case of a 58-year-old man who developed wrinkle and pigmentation around right hand, face and neck for ten years. Coix-seed Reactive Derivatives (CRD) was administrated orally 2.1g twice a day for 6 months. These lesions were improved in the third month, and a dramatic response was obtained at the end of 6 months of treatment. Further research is needed to define the optimal dose and duration of CRD intake.
ABSTRACT
Evidence that Coix-seed Reactive Derivatives (CRD) intake might be effective for allergic conditions is gradually accumulated. Therefore, we studied the influence of CRD intake on Th1/Th2 Balance. Eight Healthy Adults were orally administrated CRD 6g/day for 4 weeks, and we measured the value of blood Th1/Th2. Th2 and Th0 decreased significantly, and Th1/Th2 relatively increased (not significant). Further studies are needed to define the immunomodulatory effects of CRD.
