The study was conducted to identify the anti-inflammatory and anti-cancer effects in sprouts of mouse-eyed bean (Rhynchosia nulubilis), ginseng (Panax ginseng), perilla (Perilla frutescens), broccoli (Brassica oleracea var. italica), and lettuce (Lactuca sativa) grown with organic germanium concentrate. Western blot analysis was performed to assess the antiinflammatory activity of the extract. All extracts exhibited noticeable anti-oxidant activity, indicating a significant correlation between the germanium content and anti-oxidant activity (p<0.05). In particular, rat-eyed bean sprouts with the highest germanium content showed significant anti-inflammatory activity (p<0.05) by significantly inhibiting the expression of the inflammatory complexes, NLRP3, cytokines IL-1β and caspase-1. Ginseng and broccoli sprouts showed strong anti-cancer properties and had high anti-oxidant effects (p<0.001). Germanium-concentrated water allows the mass production of agricultural products containing high concentrations of organic germanium. Agricultural produce grown with germanium concentrate add organic germanium to various physiological active ingredients, increasing the anti-oxidant and anti-cancer effects. These results strongly suggest that agricultural products containing high germanium concentrations can be used as novel health supplements to improve health.

Polycrystalline germanium (Ge) thin films were grown by metal organic chemical vapor deposition (MOCVD) using tetra-allyl germanium [Ge(allyl)4], and germane (GeH4) as precursors. Ge thin films were grown on a TiN(50nm)/SiO2/Si substrate by varying the growth conditions of the reactive gas (H2), temperature (300-700˚C) and pressure (1-760Torr). H2 gas helps to remove carbon from Ge film for a Ge(allyl)4 precursor but not for a GeH4 precursor. Ge(allyl)4 exhibits island growth (VW mode) characteristics under conditions of 760Torr at 400-700˚C, whereas GeH4 shows a layer growth pattern (FM mode) under conditions of 5Torr at 400-700˚C. The activation energies of the two precursors under optimized deposition conditions were 13.4 KJ/mol and 31.0 KJ/mol, respectively.

이 실험의 목적은 침엽수(Paraserianthes falcataria) 와 활엽수(Shoreasp) 골목에서 두 개의 Ganoderma lucidum 균주의 자실체 발생과 성장을 연구하고 자실체의 organic germanium 과 crude ganoderic acid 함량을 측정하기 위함이다. 두 개의 Ganaderma lucidum중 하나는 인도네시아 본지에서 분리한 것이고 또 다른 하나는 Fungi Perfecti, USA에서 구입한 것을 사용하였다. 일반적으로 활엽수에서 생성된 자실체의 농도가 침엽수에서 자란 것보다 훨씬 높다. 두 종류의 골목 모두에서 상업용 균주에서 생산된 자실체의 organic germanium 농도가 인도네시아의 균주에서 생산된 자실체의 organic germanium 농도보다 높았다. 이에 반하여 버섯 자실체의 crude ganoderic acid 농도는 두 개의 균주로부터 생산된 자실체에서 거의 같은 농도를 보였다. 인도네시아 균주는 상업용 분리균주와 비교했을 때 생산된 자실체의 총 organic germanium과 총 crude ganoderic acid의 생산성이 높았다.

Background: This study was conducted to investigate the effects of germanium treatment on the growth and organic germanium production in the roots of Oplopanax elatus plantlets. Methods and Results: O. elatus plantlets were cultured in Murashige and Skoog (MS) medium with different concentrations of germanium dioxide (GeO2) to analyze optimum growth conditions. Exogenous treatment of 10 ㎎/ℓ GeO2 promoted growth and an increase in the contents of chlorophyll a, b and carotenoid in O. elatus. The germanium accumulation and production in roots of O. elatus plantlets treated with organic germanium reached the highest levels. The growth of the aerial and underground portion of O. elatus with organic germanium was greater than that of the control. The accumulation and production of organic germanium reached the highest level (40.89 ㎍/plantlet) with the treatment of 50 ㎎/ℓ GeO2. Antioxidant activity measured by DPPH and ABTS assays also increased with the germanium treatment and improved the DPPH and ABTS radical activity by 200% compared with that in the control. In addition, the total phenol and flavonoid contents of the plantlets with a treatment of 50 ㎎/ℓ GeO2 were higher than in the control. Conclusions: Taken together, the growth of O. elatus was increased with the treatment of 50 ㎎/ℓ GeO2 germanium and the biological references improved, with increased antioxidant activity and organic germanium production.
