| antihormonal effects of plant extracts: iodothyronine deiodinase of rat liver is inhibited by extracts and secondary metabolites of plants. | aqueous extracts from plants such as lycopus virginicus , melissa officinalis ( laminaceae ), and lithospermum officinale ( boraginaceae ), containing various antihormonal components, also inhibit both the extrathyroidal enzymic t4-5'-deiodination to t3 and the t4-5'-deiodination. the effects were dose dependent and ultimately complete using rat liver microsomes as a source of the enzyme in vitro. the "specific inhibitory activity" of extracts depends on the plant species used and the extraction ... | 1984 | 6724503 |
| inhibition by certain plant extracts of the binding and adenylate cyclase stimulatory effect of bovine thyrotropin in human thyroid membranes. | the present studies were undertaken to explore the mechanism by which, as previous studies have shown, freeze-dried aqueous extracts (fde) of plants of the species lycopus virginicus and lycopus europaeus, melissa officinalis (laminaceae), and lithospermum officinale (boraginaceae) have the ability to inhibit at least many of the effects of exogenous and endogenous tsh on the thyroid gland. to this end, we have examined the in vitro effects of fde from these plants on the ability of bovine tsh ( ... | 1984 | 6745167 |
| extracts and auto-oxidized constituents of certain plants inhibit the receptor-binding and the biological activity of graves' immunoglobulins. | freeze-dried extracts (fde) of the plants lycopus virginicus, lycopus europaeus, melissa officinalis, and lithospermum officinale, as well as products of the oxidation of certain of their constituents, have been shown to exert antithyrotropic activity by virtue of their ability to form adducts with tsh that bind weakly, if at all, to the tsh receptor. the thyroid-stimulating immunoglobulin g (igg) found in the blood of patients with graves' disease (graves'-igg) resemble tsh in their ability to ... | 1985 | 2985357 |
| the components of melissa officinalis l. that influence protein biosynthesis in-vitro. | an investigation of an inhibiting activity of a substance(s) in a tanninless extract from melissa officinalis leaves on protein biosynthesis in-vitro has been made. at least two components which inhibited protein biosynthesis were present in the extract; these were caffeic acid and an unidentified glycoside. freshly prepared buffered solutions of caffeic acid inhibited protein biosynthesis less than solutions stored for several days at room temperature (20 degrees c). in this case derivatives of ... | 1986 | 2879007 |
| [comparative studies of the sensitizing capacity of drugs used in herpes simplex]. | experimental sensitization of guinea pigs with 9 commonly used or still tested antiviral drugs revealed a very low sensitizing power for these when compared with tromantadine. in a former investigation tromantadine had been shown to be a moderate sensitizer. while ethoxyuridine, bromovinyl deoxyuridine and phosphono formiate gave no response in the animals, aciclovir, vidarabine, idoxuridine, trifluorothymidine, proclu and an extract of lemon balm (melissa officinalis) only induced weak reaction ... | 1986 | 2949957 |
| rosmarinic acid: a new inhibitor of complement c3-convertase with anti-inflammatory activity. | rosmarinic acid (ra) is a naturally occurring compound, isolated from rosmarinus officinalis or melissa officinalis which inhibits the in vitro immunohaemolysis of antibody-coated sheep erythrocytes by guinea pig serum. in further experiments this reduced immunohaemolysis was found to be due to inhibition of the c3-convertase of the classical complement pathway. the threshold concentration for inhibition of c3-convertase was 10(-6) mol/l. ra with an optimal inhibitory concentration between 5 and ... | 1988 | 3198307 |

| neurotropic action of the hydroalcoholic extract of melissa officinalis in the mouse. | a lyophilised hydroalcoholic extract of melissa officinalis l. (lamiaceae) has been evaluated for behavioral effects in mice. according to the traditional use of m. officinalis, sedative properties have been confirmed for low doses by the decrease of behavioral parameters measured in a non-familiar environment test (staircase test) and in a familiar environment test (two compartment test). with high doses, a peripheral analgesic activity was obtained by reducing the acetic acid-induced pain (wri ... | 1991 | 1891490 |
| antiherpes effect of melissa officinalis l. extracts. | studies were carried out on the virucidal and antiviral effects of melissa officinalis l. extracts (m1, m3, m3 and m4) with respect to herpes simplex virus type 1 (hsv-1). virucidal effect was registered within 3 and 6 hours of treatment using m4 administered in mtc. the remaining extracts inactivate the virus at the 12th and 24th hour. no significant values of inhibiting activity of m1, m2, and m3 on the same virus in vitro or in vivo were demonstrated. the presence of caffeic, rosmarinic and f ... | 1993 | 8390134 |
| antimicrobial activity of essences from labiates. | bacteria, filamentous fungi and yeasts were subjected to the action of lavandula officinalis, melissa officinalis and rosmarinus officinalis essences in a steam phase, using a microatmospheric technique. due to the methodology employed, l. officinalis essence was more active in filamentous fungi than the other essential oils studied. all three essences possessed a similar degree of activity against the micro-organisms tested, though a relatively higher activity was seen in the case of m. officin ... | 1995 | 7630324 |
