Objective : This experiment was performed in order to study the effect of an aqueous extract of Salviae radix root(SRRAE) on NO production and NOS gene induction from macrophages Methods : To investigate dose-dependent effects of SRRAE for NO release on the $rIFN-{\gamma}-treated$ macrophages, the cells were incubated for 6 hrs in a medium containing $rIFN-{\gamma}$ (5 U/ml), stimulated with SRRAE and incubated in a CO2 incubator. The cells were treated with 5 U/ml $rIFN-{\gamma}$ plus 100 g/ml of SRRAE, Then, the cells were incubated with various concentrations of NGMMA at $37^{\circ}C$ for 48 hrs, Results : SRRAE had no effect on NO production by itself, whereas recombinant $interferon-{\gamma}(rIFN-{\gamma})$ alone showed modest activity, When SRRAE was used in combination with $rIFN-{\gamma}$, there was a marked cooperative induction of NO production in a dose-dependent manner. The optimal effect of SRRAE on NO production was shown at 6hrs after treatment with $rIFN-{\gamma}$. The SRRAE-induced production of NO was inhibited by NG-monomethyl- L-arginine(NGMMA) and arginase. $rIFN-{\gamma}$ in combination with SRRAE showed a marked increase of the expression of the inducible NOS(iNOS) gene. In addition, the effect of SRRAE was mainly dependent on the SRRAE-induced tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ secretion. Conclusions : SRRAE induces NO production from macrophages as a result of SRRAE-induced $TNF-{\alpha}$ secretion. SRRAE may provide a second signal for synergistic induction of NO production in macrophages already induced to express iNOS gene by $rIFN-{\gamma}$.

Dansam, the root of Salvia miltiorrhiza BGE. (Labiatae), has a bitter and a slightly 'cold' property. and is nontoxic. It has been used for the treatment of diseases such as tumors, bruises, gynecologic diseases, menoxenia, anemia and so forth. As an oriental medicine pathway, anal therapy has many kinds of treatments, Retention enema is one the most useful, advantageous methods of anal therapy. This experiment was performed in order to study the effect of an aqueous extract of Salviae radix root(SRRAE) on Immediate type allergic reaction by Retention enema. The results were obtained as follows, 1. SRRAE inhibited compound 48/80-induced Immediate type allergic reaction 100% with the dose of 0.1g/kg by anal treatment. However, SRRAE showed no significant inhibitory effect on the same reaction by oral treatment. When mice were pretreated with SRRAE at a concentration ranging from 0.001 to 1.0g/kg, by intra-anal treatment, the serum histamine levels were reduced in a dose-dependent manner. 2. SRRAE also inhibited by 79.8% local cutaneous allergic reaction activated by anti-dinitrophenyl (DNP) IgE. 3. SRRAE close-dependently inhibited the histamine release from rat peritoneal mast cells(RPMC) by anti-DNP IgE., but SRRAE not inhibited compound 48/80-induced histamine release. 4. SRRAE dose-dependently inhibited tumor necrosis $factor-\;{\alpha}$ $(TNF-\;{\alpha}$) production from RPMC by anti-DNP IgE. Moreover, the level of cAMP in RPMC, when SRRAE was added, significantly increased compared with that of a normal control. According to the above results, anal therapy(Retention enema) of SRRAE may be beneficial in the treatment of systemic and local Immediate type allergic reactions.
