Poisoning by Phytolacca esculenta commonly occurs by misidentification as other edible plants. The root of Phytolacca esculenta is similar to other roots, such as kudzu, balloon flower, codonopsis lanceolata, and ginseng. The author experienced four cases of Phytolacca esculenta intoxication due to misidentification as a ginseng. We report on these cases with a review of the literature.

PURPOSE: Although Pokeweed intoxication is relatively less severe, thereis little data onthe clinical presentation ofPokeweed intoxication in Korea. This study examined the clinical aspectsto providebasic data for evaluating Pokeweed intoxication. METHODS: A retrospective study by a chart review was performedon 19 patients who ingested Pokeweed and presented to anacademic emergency department with an annual census of 40,000 between March 2012 and May 2012. RESULTS: Nineteen patients were identified. All patients wereintoxicated unintentionally. The most common symptoms were vomiting with diarrhea and abdominal pain. The onset time varied, but occurs 30 minutes to 5 hours post ingestion of Pokeweed. All patients were discharged without fatal complications. CONCLUSION: Compared to previous reports, mostpokeweed poisoning patients complain of gastrointestinal symptoms. Supportive care is the mainstay of the management of pokeweed intoxication. All symptoms were resolved over a 24 to 48 hour period.

OBJECTIVETo provide evidence for establishing an efficient method of growing Panax quinquefolium by rotation of crops.

METHODFour-year old P. quinquefolium was cultivated in water and soil cultures. Biological assays were conducted with the aqueous extracts of P. quinquefolius, Fructus Perillae and roots of Coix lacryma-jobi. P. quinquefolium was cultivated in the soil where purple Perilla frutesens and C. lacryma-jobi were grown previously. The effects of rotation were determined.

RESULTThe stems, leaves and fibrous roots of Panax quinquefolium contained allelopathic substances. When the concentration of the allelopathic substances exceeded 1g per kg soil, P. quinquefolius could not grow. On the other hand, when the concentration of allelopathic substances fell below 0.2 g per kg soil, the rate of seedling growth was decreased by 25%. When P. quinquefolius was cultivated in the soil in which purple Perilla frutesens had previously grown, or in the soil supplemented with Fructus Perillae, the rates of seedling growth and the yield were raised by 26.8% and 11.5% tively, in comparison with the controls.

CONCLUSIONRotation of Panax quinquefolium and Perilla frutesens was shown to be a good way for the cultivation of the former. During the growing process, application of Fructus Perillae to the soil could further enhance the growth and of Panax quinquefolium.

Recently, some patients have visited the emergency department for treatment of different symptoms of acute poisoning after intake of unidentified herbs, which can be mistaken for wild edible greens, because wild edible greens are good for health and contain vitamins, enzymes, minerals, fibers, and anticancer materials. Winter or early spring, is extremely high, with rapid onset of severe symptoms of poisoning. There have been no reports of poisoning by SymplocarpusRenifolius in Korea, however, we report on three severe cases involving patients who experienced cardiogenic shock with nausea, vomiting, abdominal pain, chest discomfort, dizziness, numbness, and general weakness.

Study of plant roots and the diversity of soil micro biota, such as bacteria, fungi and microfauna associated with them, is important for understanding the ecological complexities between diverse plants, microbes, soil and climates and their role in phytoremediation of contaminated soils. The arbuscular mycorrhizal fungi (AMF) are universal and ubiquitous rhizosphere microflora forming symbiosis with plant roots and acting as biofertilizers, bioprotactants, and biodegraders. In addition to AMF, soils also contain various antagonistic and beneficial bacteria such as root pathogens, plant growth promoting rhizobacteria including free-living and symbiotic N-fixers, and mycorrhiza helping bacteria. Their potential role in phytoremediation of heavy metal (HM) contaminated soils and water is becoming evident although there is need to completely understand the ecological complexities of the plant-microbe-soil interactions and their better exploitation as consortia in remediation strategies employed for contaminated soils. These multitrophic root microbial associations deserve multi-disciplinary investigations using molecular, biochemical, and physiological techniques. Ecosystem restoration of heavy metal contaminated soils practices need to incorporate microbial biotechnology research and development. This review highlights the ecological complexity and diversity of plant-microbe-soil combinations, particularly AM and provides an overview on the recent developments in this area. It also discusses the role AMF play in phytorestoration of HM contaminated soils, i.e. mycorrhizoremediation.

OBJECTIVE: To observe the pathological changes of major organs in rats with acute Dysosma versipellis poisoning and investigate the toxic mechanism and the injuries of target tissues and organs. METHODS: Forty Sprague-Dawley (SD) rats were randomly divided into three experimental groups, which were given the gavage with 0.5, 1.0 and 2.0 LDo doses of Dysosma versipellis decoction, and one control group, which was given the gavage with 1.0 LD0 dose of normal saline. The rats were sacrificed 14 days after Dysosma versipellis poisoning and samples including brain, heart, liver, lung, and kidney were taken. After pathological process, the pathological changes of the major organs and tissues were observed by light microscope and electron microscope. The experimental data were statistical analyzed by chi2 test. RESULTS: The observations of light microscopy: loose cytoplasm of neurons with loss of most Nissl bodies; swelling of myocardial cells with disappearance of intercalated disk and striations; hepatocellular edema with ballooning degeneration; and swelling epithelial cells of renal proximal convoluted tubule with red light coloring protein-like substances in the tube. The observations of electron microscopy: the structures of cell membrane and nuclear membrane of neurons were destroyed; cytoplasm of neurons, obvious edema; and most organelles, destroyed and disappeared. The mortalities of rats after acute poisoning of the four groups increased with doses (P < 0.05). CONCLUSION Acute Dysosma versipellis poisoning can cause multi-organ pathological changes. There is a positive correlation between the toxic effect and the dosage. The target tissues and organs are brain (neurons), heart, liver and kidney.

Phytolacca americana poisoning is a benign plant intoxication that causes gastrointestinal symptoms, including abdominal cramps, vomiting, diarrhea, and gastrointestinal bleeding. Other signs and symptoms include diaphoresis, salivation, visual disturbance, and seizures or mental changes. We report two cases of patients who experienced confusion and abdominal pain, vomiting, and hematemesis after oral ingestion of pokeweed. A 60-year-old female with confusion and a 67-year-old female with abdominal pain, vomiting, and diarrhea were admitted to the emergency department after pokeweed poisoning. After supportive treatment of hydration and gastrointestinal medication, the two patients showed full recovery within 24 h and were discharged from the hospital.
