Kerontokan rambut merupakan masalah yang dapat mengganggu penampilan. Ekstrak teh hijau dengan kadar 5 % terbukti menstimulasi pertumbuhan rambut (Sumakdjaja, dkk., 2008). Zat aktif dalam teh hijau (Camellia sinensis L) yang berkhasiat sebagai penyubur rambut adalah senyawa katekin dan turunannya. Senyawa flavonoid teh hijau terdiri dari epikatekin, (EC), epikatekin galat (ECG), dan epigalokatekin galat (EGCG). Selain itu juga terdapat asam galat, galokatekin galat (GCG), galokatekin (GC), katekin galat (CG) katekin (C), vitamin B dan vitamin C (Agus, 2007) yang mampu memperkuat akar rambut, mencegah kerontokan rambut, menghambat radikal bebas, menetralkan racun, dan melindungi kulit kepala dari infeksi. Formula sediaan kosmetik dan makanan berbahan aktif the hijau telah menyita perhatian masyarakat. Penyubur rambut berbahan aktif ekstrak teh hijau berbentuk gel belum dijumpai di kalangan masyarakat. Berdasarkan fenomena tersebut, penelitian ini bertujuan mengembangkan formula gel penyubur rambut berbahan aktif ekstrak teh hijau. Penelitian ini dilakukan dengan membuat empat formula, yaitu formula I (carbopol 1%, TEA 0,3%, gliserin 1 %), formula II (CMC Na 3%, gliserin 1%,), formula III (PEG 400 72 %, PEG 4000 8%, gliserin 1%) dan formula IV (carbopol 0,75%, TEA 2%, PEG 400 12 % gliserin 1 %. Masing-masing formula mengandung ekstrak teh hijau dengan kadar 5%, pengawet nipagin 0,1 %, dan natrium metabisulfit 0,1%, sediaan dibuat 100 gram. Keempat  gel yang diperoleh kemudian diuji kualitas sediaannya meliputi uji organoleptis, uji homogenitas, uji pH, uji daya sebar, uji daya lekat, uji daya proteksi, uji iritasi primer, uji aseptabilitas, serta uji aktivitas penyubur rambut. Dari penelitian diketahui bahwa formula gel yang paling optimal adalah formula I yang terdiri dari carbopol 1 %, TEA 0,3 %, dan gliserin 1%. Formula I menunjukkan konsistensi gel yang baik, mempunyai aktivitas penyubur rambut paling tinggi, tidak mengiritasi kulit, serta mempunyai sifat aseptabilitas yang baik.

AbstractMaternal vitamin intake during pregnancy is crucial for pregnancy outcomes and the child's subsequent health. However, there are few valid instruments for assessing vitamin intake that address the effects of nausea and vomiting during pregnancy (NVP). This study aimed to investigate the validity of a FFQ concerning vitamin intake during early and late pregnancy with and without NVP. The participants comprised 200 Japanese pregnant women who completed the FFQ and from whom blood samples were taken in early and late pregnancy. Energy-adjusted dietary vitamin intakes (vitamin C, folate, vitamin B6, vitamin B12, vitamin A, vitamin E and vitamin D) from FFQ were compared with their blood concentrations. A subgroup of women with NVP was investigated. In early pregnancy, significant correlations between FFQ and biomarkers were observed for vitamin C (r0·27), folate (r0·18) and vitamin D (r0·26) in women with NVP and for vitamin A (r0·18), vitamin B12(r0·24) and vitamin D (r0·23) in women without NVP. No significant correlations were observed in either group for vitamins B6or E. In late pregnancy, similar significant associations were observed for vitamin C (r0·27), folate (r0·22), vitamin B6(r0·18), vitamin B12(r0·27) and vitamin A (r0·15); coefficients were higher among women without NVP. Our study demonstrates that the FFQ is a useful tool for assessing intake of several important vitamins in early and late pregnancy regardless of NVP status.

Set Up

In this paper, the influence of the modification method applied to ground vulcanizate (GV) on the properties of elastomeric compositions based on nitrile rubber is discussed. Modified GV has been mixed with the elastomeric composition, which is used for the manufacturing of oil-petroleum-resistant rubber products.The work takes into consideration two types of GV with different chemical nature. The first GV type is rubber crumb produced from end-of-life tires. The second GV type was obtained from rubber wastes based on nitrile rubber. Three methods of the modification are compared in the research: mechanical activation in a planetary ball mill, swelling in a Polyethylene glycol (PEG-400) medium, and the mechano-chemical transformation of GV with PEG-4000. It is shown that depending on the dosage addition of GV modified with PEG-4000 reduce the compression set up for (16.1±0.7%), the strength decreases only by 2.1–8.3%, and the elongation at break increases by 0.8–10.3% compared to rubber without additives.

This review describes about the literatures addressing the role of vitamin supplementation in schizophrenia. Evidence is suggesting that vitamin supplementation includes Vitamin A, Vitamin D, Vitamin E, Vitamin B complex, and Vitamin C may be important in treatment. In schizophrenia, patients may have increased level of homocysteine (Hcy), due to the polymorphism in methylenetetrahydrofolate reductase and hypofunction of N-methyl-D-aspartate receptors. The vitamins main effects are reduced the Hcy level and maintain dopamine and serotonin levels. Add-on treatment with high-dose B vitamins including B6, B9, and B12 and also Vitamin D can significantly reduce symptoms of schizophrenia more than standard treatments alone.

Cross Sectional

Postherpetic neuralgia (PHN) is the most common complication of herpes zoster (HZ). The aim of the present study was to compare the nutritional status of PHN patients with that of healthy controls, and then to identify risk factors for PHN using multivariate multiple logistic regressions. In the present cross-sectional study, we prospectively enrolled fifty PHN patients for at least 3 months and fifty healthy controls. We selected nine circulating nutrients including ionised Ca, Zn, retinol, folic acid, vitamin B12, vitamin C, α-tocopherol, γ-tocopherol and lycopene associated with both immunity and the modulation of neuropathic pain, and measured their concentrations in plasma/serum. Concentrations of ionised Ca, Zn, vitamin C and vitamin B12were significantly lower in PHN patients than in controls after excluding those patients receiving supplements since the outbreak of HZ. The prevalence of either mild/marginal or severe deficiencies for any of the nine selected circulating nutrients in PHN patients (92 %) was much higher than that in controls (46 %) (P < 0·001). Lower concentrations of vitamin C ( ≤ 45·0 μmol/l), ionised Ca ( ≤ 1·05 mmol/l) and Zn ( ≤ 0·91 g/l) were found to increase independently the risk of PHN using binary variable (dichotomy) analyses with both PHN patients and controls in a multivariate logistic regression analysis. No significant correlations existed between the risks of PHN and the concentrations of retinol, folic acid, vitamin B12, lycopene or α:γ-tocopherol ratios. Thus, lower concentrations of circulating nutrients, namely vitamin C, ionised Ca or Zn, are probably a risk factor in Taiwanese patients with PHN.
