This study examined variation in Cd and Pb uptake among different medi cinal plants grown under the same soil environment together with immobilizing effect of lime to decrease these metals accumulation by the medicinal plants. For this, lime was incorporated into a heavy metal-contaminated soil at 1% followed by cultivation of seven different annual and 5 different biennial medicinal plants. In order for comparison, control soil without lime treatment was included and all the pot trials were carried out four replicates. Cadmium and Pb concentrations in medicinal plant roots grown in the control soil varied between 0.5 and $2.8mg\;kg^{-1}$ for Cd and 3.2 and $82.4mg\;kg^{-1}$ for Pb. The highest accumulation occurred in C. officinale and the lowest in D. batatas. Lime application decreased average Cd and Pb concentrations in the examined medicinal plants from $1.3mg\;kg^{-1}$ and $25.7mg\;kg^{-1}$ to $0.6mg\;kg^{-1}$ and $11.9mg\;kg^{-1}$, respectively in comparison with those grown in the control soil.

Background: Ginsenoside Re (Re) is one of the major components of Panax ginseng Meyer. Ginsenoside $Rk_3$ ($Rk_3$) is a secondary metabolite of Re. The aim of this study was to investigate and compare the effects and underlying mechanisms of Re and $Rk_3$ on cyclophosphamide-induced myelosuppression. Methods: The mice myelosuppression model was established by intraperitoneal (i.p.) injection of cyclophosphamide. Peripheral blood cells, bone marrow nucleated cells, and colony yield of hematopoietic progenitor cells in vitro were counted. The levels of erythropoietin, thrombopoietin, and granulocyte macrophage colony-stimulating factor in plasma were measured by enzyme-linked immunosorbent assay. Bone marrow cell cycle was performed by flow cytometry. The expression of apoptotic protein bcl-2, bax, and caspase-3 was detected by Western blotting. Results: Both Re and $Rk_3$ could improve peripheral blood cells, bone marrow nucleated cell counts, thymus index, and spleen index. Furthermore, they could enhance the yield of colonies cultured in vitro and make the levels of granulocyte macrophage colony-stimulating factor, erythropoietin, and thrombopoietin normal, reduce the ratio of $G_0/G_1$ phase cells, and increase the proliferation index. Finally, Re and $Rk_3$ could upregulate the expression of bcl-2, whereas they could downregulate the expression of bax and caspase-3. Conclusion: Re and $Rk_3$ could improve the hematopoietic function of myelosuppressed mice. The effect of $Rk_3$ was superior to that of Re at any dose. Regulating the levels of cytokines, promoting cells enter the normal cell cycle, regulating the balance of bcl-2/bax, and inhibiting the expression of caspase-3 may be the effects of Re and $Rk_3$ on myelosuppression.

Objectives : Through the researching on the records of "Bullsusan" in Korean Traditional Medical Books, gain the literature evidence for adaptation to these days child labor as a pre-labor keeping herbal medicine. And have detailed consideration on the constitution of prescription and medicinal effect & adaptation diseases of "Bullsusan". Methods : First, researched the records of "Bullsusan" in Korean Traditional Medical Books which were included at A Series of Korean Medicine(韓國醫學大系) and analysed component ratio, nickname, herbal manufacture and drug processing method, medicinal effect and adaptation diseases. Second, referred related Korean and Chinese researches that examined the medicinal effect and adaptation diseases of "Bullsusan" by scientific experimentation. Conclusions : We found total 46 records of "Bullsusan" from 20 kinds of Korean Traditional Medical Books included at A Series of Korean Medicine. Prescription component ratio of Angelicae Gigantis Radix and Cnidii Rhizoma were 3:2, 1:1, 2:1, 1:1. 3:2 had most 20 records and 1:1 had second 14 records. Especially 1:1 had a tendency of having nickname "Goonguitang", but not must had. First herbal manufacture was powder, it had 8 records. First drug processing method was decocting with water and alcohol, had 19 records. Medical Effects of "Bullsusan" can be induced to next 8, that were "remove get bad blood, give birth new blood", "easy labor by reducing fetal volume", "acceleration of labor", "test of fetal survival, elimination of dead embryo", "elimination of placenta", "revive", "allaying pain", "nourish the blood". From these medical effects, 9 adaptation diseases can be induced. That were "threatened abortion", "womb ache and vaginal bleeding by spontaneous abortion", "pre-labor keeping(prevention of hard labor)", "acceleration of labor", "hard labor", "missed abortion", "postnatal vaginal bleeding, dizziness, asthma, headache, womb ache", "postnatal mastoptosis and mastodynia", "first aid symptom like as dizziness, unconsciousness, stroke caused by excessive bleeding". The medical effect of "acceleration of labor" and "elimination of placenta" have been examined by modern clinical research. The effect of "remove get bad blood, give birth new blood", "allaying pain" and "nourish the blood" have been examined by modern experimental study. But overdosing on "Bullsusan" to pregnant mouse can cause natural abortion, so the proper dose of "Bullsusan" in pregnant period is very important.

N-Aryl-N'(4-hydroxy-6-methyl-2-pyrimidinyl)guanidines (IIa-c) were prepared by cyclization of N-arybiguanides (Ia-c) with ethyl acetoacetate. Coupling of compounds (IIa-c) with the appropriate diazotized arylamine gave N-aryl-N'-(5-arylhydrazono-6-methyl-4-oxopyrimidin-2-yl) guanidines (IIIa-f). Whereas, their chlorination with phosphorus oxychloride followed by treatment of N-aryl-N'-(4-Chloro-6-methyl-2-pyrimidinyl)guanidimes (IVac) with the appropriate arylamine afforded the corresponding 4-arylamino derivatives (Vaf). Compounds (IIa-f) were also formed when compounds (1a-c) were treated with ethyl 2-arylhydrazono-3-oxobutyrates. The antimircobial testing of some of the prepared compounds against some pathogenic microorganisms revealed that only two have a marked effect against Escherichia coli.

This study was conducted to investigate the effects of medicinal plants with additives on storage characteristics of sausage. The water activity of the sausage with the additives tended to decrease with the storage time: the highest value was shown in the Angelica added sausage samples, in both cases added with dried powder as well as with extracted powder. The Paeonia extract powder added sausage had the lowest pH value. The herbal plant added sausages showed the lowest cooking and storage losses among all. The values of TBA (thiobarbituric acid value) and VBN (volatile basic nitrogen) increased with storage time, but the values of the sample with the extract powder additive were lower than those of the freeze-dry powder additive. Total plate counts of bacteria increased with storage time fur all samples, but those for the samples with Pueraria, Platycodon, Angelica, Bupleurum and Paeonia additives exhibited lower values than the control. From the above results, the sausages with medicinal plant additives showed the superior storage safety and quality characteristics.

In this study, we investigated the effect of Solanum nigrum aerial parts (SNAP) on macrophage activation and macrophage autophagy in RAW264.7 cells. SNAP increased the production of immunostimulatory factors and phagocytosis in RAW264.7 cells. TLR4 inhibition blocked SNAP-mediated production of immunostimulatory factors. In addition, the JNK inhibition reduced the SNAP-mediated production of immunostimulatory factors, and the SNAP-mediated JNK activation was blocked by the TLR4 inhibition. SNAP activated macrophage autophagy. TLR4 inhibition blocked SNAP-mediated macrophage autophagy and inhibition of p38 and JNK attenuated SNAP-mediated macrophage autophagy. These findings indicate that SNAP may induce TLR4/JNK-mediated macrophage activation and TLR4/p38 and JNK-mediated macrophage autophagy.
