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
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
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
We examined the influence of hot water extract of coix seed (Coix lacryma-jobi L. var. ma-yuen Stapf) with husks on facial skin. Ten females (28-58 years old) took hot water extract of coix seed with husks 1 g/day for 8 weeks, and various skin parameters were measured. The results showed that the total amount of subsurface reflection of blue light, which is an index of skin translucency, increased significantly after 8 weeks of intake (p = 0.011). In addition, skin texture improved significantly after 4 and 8 weeks of intake (p = 0.007, p = 0.042). Additionally, the condition of tape-stripped stratum corneum also indicated significant improvement after 4 and 8 weeks intake (p = 0.0002, p = 0.020). These results suggested that the hot water extract of coix seed with husks exhibited effects even at 1 g/day, which is less than in previous reports.
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
We evaluated the effects of the extract of Coix-seed Reactive Derivatives (CRD) on female skin pigmentation. Ninety females with facial pigmentation were assigned randomly to 3 groups and CRD (2g/day, 4g/day or placebo) was administrated for 8weeks. We confirmed the safety of CRD, and both the rate of change of facial pigmentation and erythema in 4g/day group decreased significantly (p<0.01). Further studies are needed to define the optimal dose of CRD.
ABSTRACT
We reported 2 cases of intractable warts and a case of intractable vaginal condyloma that were cured by Coix-seed Reactive Derivatives (CRD) and vitamin (folic acid・B1・B6・B12）combination therapy. Further studies are needed to define the efficacy of this treatment.
ABSTRACT
Functional food research encompasses several types of study designs, including observational studies and randomized clinical trials (RCTs). To clarify the functions of Coix-seed Reactive Derivatives(CRD), we observed 7 refractory skin diseases: case1 Pustulosis palmaris et plantaris, case2 atopic dermatitis, case3 hand eczema, case4 contact dermatitis, case5 wrinkles of a face, case6 acne vulgaris and case7 lentigo senilis(senile pigment freckle). Although CRD intake seemed to be effective in all cases, further studies are needed to define the optimal dose and duration.
ABSTRACT
We evaluated the effect of Coix seed with husks on bovine cutaneous papillomas. Boiled coix seed with husks was administered to two cows with intractable cutaneous papillomas. The nodules disappeared or diminished on week 6. Further examination will be needed to confirm these findings.
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.
ABSTRACT
CRD, a Coix-seed Reactive Derivatives, has a novel mechanism in the treatment of various diseases. In the present study, a fluorometric-based high throughput method using cytochrome P450 (CYP)screening kit was adopted to evaluate in vitro inhibition potential of CRD (CRD 1 and CRD 2) on CYP isoenzymes by calculating remaining enzyme activities and inhibitory potential (IC50 values) using the determined values of fluorescence intensity. IC50 of CRD 1 and CRD 2 were as follows: CYP3A4; >500 µg/ml, 490 µg/ml, CYP2D6; >500 µg/ml，>500 µg/ml，CYP2C9; >500 µg/ml，339 µg/ml, respectively. The result showed that CRD exhibited little activity in the inhibition of CYP3A4, CYP2D6 and CYP2C9.
ABSTRACT
<i>Coix lacryma-jobi</i> L. <i>var. ma-yuen</i> Stapf is a grass long been used in traditional medicine as a nourishing food and reported to possess pharmacological effects including anti-tumor, anti-obesity, anti-diabetic, etc. In order to evaluate the possible mutagenicity of the hot water extract of all parts (husks, pellicles, and astringent skin) of the food, we performed a reverse mutation test in bacteria, a mouse lymphoma assay and a mouse micronucleus test. The results of all tests were negative. It was concluded that the extract has no mutagenicity for living bodies.<br>
