We have investigated that a couple of soft ferrite ceramic powders having a spinal structure have shown the effect on growth and secondary metabolites production of some medicinal plants cultured in vitro. The addition of the ceramic powders as bare state to culture medium has stimulated the growth of Achyranthes japonica callus and plantlet, adventitious root of Hyoscyamus niger and Platycodon grandiflorum hairy root about 65, 75, 150 and 50%, respectively. Whereas Centella asiatica callus and plantlet, Scopolia parviflora hairy root, and Hyoscyamus albus adventitious root were not affected markedly. Moreover, the ceramic powder has enhanced the growth of H. niger adventitious roots even under conditions of irradiating alone without any direct contact between ceramic powder and media. Based on growth stimulation effect, the ceramic powders have enhanced the gross production of tropane alkaloid in H. niger adventitious root, and polyacetylene in P. grandiflorum hairy root about 35 and 30%, respectively.

The aim of this study was to evaluate if a composition of herb extracts, PLX-PLS was effective to treat atopic dermatitis (AD) in mice. SPZZC is a composition of herb extracts containing the roots of Scopolia parviflora and Paeonia lactiflora, the herb of Zizania caudiflora, the fruit of Ziziphus jujuba and the leaf of Chinese arborvitae. AD in BALB/c mouse was induced by patching ovoalbumin on the backside, while it in NC/Nga mouse was induced by repeated application of 1-chloro 2,4-dinitrobenzene (DNCB). Mice were topically treated with SPZZC or Domohorn ointment on the backside for 2 weeks (BALB/c) or 1 week (NC/Nga). Scratching behavior, clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were measured. After AD induction, scores of scratching behavior and clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were increased. Treatment with SPZZC significantly decreased scores of scratching behavior and clinical skin severity in a dose dependent manner in NC/Nga and BALB/c mice. Treatment with SPZZC 2% significantly decreased also the levels of WBC, neutrophil, eosinophil and total serum IgE. Especially, treatment of SPZZC 2% reduced more rapidly score of clinical skin severity than clobetasol cream. These results suggest that the SPZZC may be an alternative substance for the management of AD.

Purpose: With the recent boom in 'eating healthy', many adults are interested in dieting to prevent future diseases. However only well trained experts can distinguish between what are edible vegetables and herbs from their poisonous look-alikes. In cases where a patient unknowingly ingests a poisonous herb, is caught off guard by the poisonous side effects that occur because of their lack of knowledge of what they have ingested. This paper will focus on the need to educate the public about the risks involved with ingesting wild vegetables and herbs and study the emergency diagnosis and treatment of poisoned patients that enter the emergency room. Method: This study was done in the spring of 2004 (from March to May) in the Kangwon Young-Seo districts of Korea. 15 subjects used in this study, entered the emergency room showing signs of toxic symptoms. Data was collected by examining subject's records. Additional data was collected by collaborating with physicians in the hospital that diagnosed and treated the subjects. Identifying the poisonous vegetable or herb is the first step to proper diagnosis and treatment. Subjects admitted to the emergency room, underwent a battery of tests: laboratory examination, ECG, radiological exam and etc. Results: The demographics of the study encompassed subjects with the average age of $50{\pm}19$ years old. There were 10 men and 5 women. Common symptoms of this study included; gastrointestinal symptoms such as nausea, vomiting, epigastric pain and so on. In the case of Caltha palustris ingestion, additional symptoms were present; bradycardia and hypotension which lasted for a long time. While cases that ingested Scopolia parviflora had little effect on vital signs but manic episodes lasted for about three days. Veratrum patulum ingestion showed signs of bradycardia and hypotension but contrary to Caltha palustris recovery was shorten by treating with dopamine. However, dizziness, headache and paresthesia of the extremities continued for a long time. Finally Sium ninsi ingestion showed visual disturbance, paresthesia of the extremities, dizziness as their initial symptoms. Conclusion: The risks involved with ingesting wild plants without the proper knowledge can lead to serious side effects and steps need to be taken to educate the public. In addition, all emergency physicians need to have a working knowledge of the symptoms and signs associated with ingesting toxic wild plants and need to treat accordingly.
