The study also shows that Equisetum hyemale can antagonize the hyperlipemia in rats. The acute toxic test has proved its low toxicity.

In: Int Urol Nephrol (1994) 26(5):507-11 ISSN: 0301-1623 The effects of seven plants with suspected application to prevent and treat stone kidney formation (Verbena officinalis, Lithospermum officinale, Taraxacum officinale, Equisetum arvense, Arctostaphylos uva-ursi, Arctium lappa and Silene saxifraga) have been studied using female Wistar rats. Variations of the main urolithiasis risk factors (citraturia, calciuria, phosphaturia, pH and diuresis) have been evaluated. It can be concluded that beneficial effects caused by these herb infusions on urolithiasis can be attributed to some disinfectant action, and tentatively to the presence of saponins. Specifically, some solvent action can be postulated with respect to uric stones or heterogeneous uric nucleus, due to the basifying capacity of some herb infusions. Nevertheless, for all the mentioned beneficial effects, more effective and equally innocuous substances are well known. €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€ *****ONDERSTEPOORT JOURNAL OF VETERINARY RESEARCH***** Meyer P Thiaminase activities and thiamine content of Pteridium aquilinum, Equisetum ramosissimum, Malva parviflora, Pennisetum clandestinum and Medicago sativa. In: Onderstepoort J Vet Res (1989 Jun) 56(2):145-6 ISSN: 0030-2465 Thiaminase type 1 and 2 activities and thiamine content of five plants were determined. Of these Pteridium aquilinum and Equisetum ramosissimum were found to have considerably more thiaminase activity and lower thiamine content than Malva parviflora, Pennisetum clandestinum and Medicago sativa.

In: Phytochemistry (1996 Jan) 41(1):37-42 ISSN: 0031-9422 Macromolecular assemblages intimately associated with biogenic silica in plants are released on solubilization of the siliceous phase by treatment with buffered aqueous solutions of HF following treatment of plant material with concentrated oxidizing acids (perchloric, nitric and sulphuric) to remove cytoplasmic contents and the largely polysaccharidic cell wall. The non-dialysable material, which may form 0.015-0.030% dry weight of the silica, has an amino acid composition rich in Pro-Glu, Pro-Lys, or Ser-Asp-Gly depending on the extent of treatment with oxidizing acids. The materials are suggested to have an intrasilica location with materials of similar composition being extracted from the branches of Equisetum telmateia (a primitive plant) and from hairs from the lemma of the grass Phalaris canariensis. The role of such material in regulating nucleation, particle growth and aggregate structure development in silicas is discussed.

In: Proc Annu Meet Am Assoc Cancer Res (1993) 34:A1818 ISSN: 0197-016X Thirty-five kinds of herbal drugs, which have been applied for treatment of tumors in this country, were selected as the experimental materials. Each of them was extracted with ethyl ether (E), ethyl acetate (EA) and methanol (M) in sequence. Among the extracts, Sophorae Flos (EA), Paeoniae Radix (EA), Equisetum hiemale herb (EA), Ferula assafoetida (E,EA), Phellodendri Cortex (E,EA), Mori Cortex radicis (EA), Sophora subprostrata (E,M) and Cnidium monnieri (E) inhibited the TPA-induced adherence of HL-60 cell to plastic substrate more than 50%. Sophorae Flos (E,EA,M), Paeoniae Radix (E,EA,M), Equisetum hiemale (E), Phellodendri Cortex (E,M), Mori Cortex radicis (M), Ferula assafoetida (M), Sophora subprostrata (EA,M) Cnidium monnieri (M) and Artemisia argyi (M) showed inhibitory effects on protein kinase C from calf brain more than 50%. The extracts showing good inhibitory effects on the adherence and enzyme were Sophorae Flos(EA), Paeoniae Radix (EA), Phellodendri Cortex (E), Saphora subprostrata (EA) and Equisetum hiemale (EA). At present, isolation of the active substances from E hiemale herb is in progress.
