Abstract
UNLABELLED CONTEXT : Terpenes and terpenoids are a diverse class of organic compounds produced by a variety of plants, particularly conifers. Chemically sensitive patients can be targeted by terpenes and terpenoids, resulting in a triggering of symptoms and pathology. Often patients cannot clear their symptoms from exposure to chemicals unless terpenes and terpenoids are avoided and neutralized along with chemical avoidance and treatment. OBJECTIVE This article evaluates the presence, diagnosis, and treatment of terpenes exposure in chemically sensitive patients. DESIGN A double-blind, placebo-controlled, 2-part study was designed to establish the chemically sensitive state of the patients in part 1, followed by a second set of challenges to determine each patient's concurrent sensitivity to terpenes and terpenoids in part 2. In all of the challenges, normal saline was used as a control. A case report illustrates the history of 1 patient and describes the authors' treatment methods. SETTING The study was developed and conducted at the Environmental Health Center of Dallas (EHC-D) because the environment within the center is 5 times less polluted than the surrounding environments, as determined by quantitative air analysis and particulate counts. PARTICIPANTS A total of 45 chemically sensitive patients at EHC-D with odor sensitivity to terpenes. The cohort included 18 males and 27 females, aged 24-62 y.Intervention • Patients were deadapted (4 d) and evaluated in a 5-times-less-polluted environment, which was evaluated using air analysis and particulate counts. After deadaptation, the patients were challenged by inhalation in a controlled, less-polluted glass steel booth inside an environmentally controlled room with an ambient air dose of the toxics in the order of parts per billion (PPB) and parts per million (PPM). These toxics included formaldehyde, pesticide, cigarette smoke, ethanol, phenol, chlorine, new sprint, perfume, and placebo. They were also challenged intradermally with extracts of volatile organic compounds (VOCs), including formaldehyde, orris root, ethanol, phenol, cigarette smoke, chlorine, newsprint, perfume, terpenes, terpenoids, and placebo. OUTCOME MEASURES Inhaled challenges recorded pulse, blood pressure, peak bronchial flow, and other signs and symptoms 30 min before and at 15-min intervals for 2 h postchallenge. Intradermal challenges recorded wheal size and the provocation of signs and symptoms. RESULTS : Different numbers of patients were tested for each terpenes source because of time-related factors or the cumulative effect of testing, which made patients unable to continue. Of 45 chemically sensitive patients in the study, 43 demonstrated sensitivity to terpenes. CONCLUSIONS This particular patient group was positive for a number of toxic and nontoxic chemicals provoking their symptoms. This study shows there was a connection between VOCs, other chemicals, and terpenes in chemically sensitive patients in a prospective cohort study. It has also shown the potential for terpenes to exacerbate symptoms of chemical sensitivity. Further research on this topic is recommended.

Abstract
Neem oil is often used externally as a traditional medicine in India. Its ingestion, even in small doses produces toxic effects like severe metabolic acidosis, seizures, renal failure and encephalopathy. Management is supportive and prognosis is generally good but fatalities may occur. Herein we report an unusual case of neem oil toxicity in a previously normal adult.

Abstract
Selected oil cakes, neem, castor and mahua, were tried independently and in combination with a chemical nematicide (carbofuran 3G) for the management of Pratylenchus delattrei in crossandra under glass house conditions. The neem oil cake was effective compared to other oil cakes used and there was a synergistic effect when the neemcake was coupled with carbofuran 3G in the management of Pratylenchus delattrei. The treatment resulted in better establishment of seedlings, and with increased plant bio-mass and flower yield.

Abstract
OBJECTIVE To describe a case of fatal mouthwash ingestion and review possible sources of toxicity. DESIGN Case report. SETTING Veterans Administration Medical Center. PATIENT Single patient with massive mouthwash ingestion. MAIN RESULTS This patient was a 45-year-old man who developed cardiovascular collapse and multiorgan system failure following a massive ingestion of mouthwash (almost 3 liters). His presentation was remarkable for a profound anion-gap metabolic acidosis and a significant osmolar gap. No other co-ingestants were identified, and he expired despite full supportive care including dialysis and mechanical ventilation. An autopsy failed to identify any other cause of death. Nonalcoholic ingredients of this mouthwash are phenolic compounds (eucalyptol, menthol, and thymol), and large-volume mouthwash ingestion will produce exposure in the reported toxic range of these ingredients. CONCLUSIONS When ingested in large quantities, the phenolic compounds in mouthwash may contribute to a severe anion-gap metabolic acidosis and osmolar gap, multiorgan system failure, and death. These compounds, in addition to alcohol, may account for the adverse effects associated with massive mouthwash ingestion.

Abstract
This paper reviews recent studies in the field of "indoor chemistry"--reactions among indoor pollutants. Advances have occurred in a number of areas. A mouse bioassay procedure has shown that ozone/terpene reactions produce products that are more irritating than their precursors, although the agents responsible for the deleterious effects remain to be determined. Indoor ozone/terpene reactions have been demonstrated to produce hydroxyl radicals, hydrogen peroxide, sub-micron particles, and ultrafine particles. New analytical techniques such as LC/MS and thermal desorption mass spectrometry have greatly improved our knowledge of the condensed-phase species associated with such particles. Indeed, the latter approach has identified a number of short-lived or thermally labile species, including organic hydroperoxides, peroxy-hemiacetals, and secondary ozonides, which would be missed by more conventional techniques. Investigators are making inroads into the poorly understood area of indoor heterogeneous chemistry. Systems studied include ozone/HVAC components, ozone/paint, and ozone/carpets. Another heterogeneous process that has been further examined is the indoor formation of nitrous acid through NO2/surface chemistry. Emissions from indoor sources that contribute to, or are altered by, indoor chemistry have also received attention. Researchers have expanded our awareness of reactive chemicals that can emanate from wood coatings and other products commonly used indoors. In a related vein, a number of recent investigations have shown that emissions from materials can be significantly altered by indoor chemistry. On the theoretical side, an outdoor atmospheric chemistry model has been modified for use as an indoor air model, the effects of ventilation rates on indoor chemistry have been simulated, and initial steps have been taken in applying computational fluid dynamics (CFD) methods to indoor chemistry.

Abstract
The case history and toxicological findings of a fatal PineSol intoxication are presented. An 89-year-old white female with Alzheimer's disease accidentally drank PineSol and was subsequently brought to the hospital where she was pronounced dead on arrival. Significant autopsy findings included acute erosive gastritis. There appeared to be no aspiration of PineSol into the lungs. Isopropanol along with 1-alpha-terpineol are the two major toxic ingredients of PineSol. The toxicological screening and quantitiation of 1-alpha-terpineol in postmortem fluids was performed by gas chromatography-mass spectrometry using a simple one-step extraction. Postmortem blood, urine, and gastric levels of 1-alpha-terpineol were 11.2 mg/L, 5.76 mg/L, and 15.3 g/L, respectively. Postmortem blood, vitreous humor, urine, and gastric acetone concentrations were 25, 31, 33, and 28 mg/dL. Postmortem concentrations of isopropanol were less than 10 mg/dL in the blood, vitreous humor, urine, and gastric contents. The cause of death was ruled acute 1-alpha-terpineol intoxication due to accidental ingestion of PineSol, presumably caused by confusion related to Alzheimer's disease.

Abstract
Nonciliated bronchiolar (Clara) cells metabolize environmental toxicants, are progenitor cells during development, and differentiate postnatally. Because differentiating Clara cells of neonatal rabbits are injured at lower doses by the cytochrome P-450-activated cytotoxicant 4-ipomeanol than are those of adults, the impact of early injury on the bronchiolar epithelial organization of adults was defined by treating neonates (3-21 days) and examining them at 4-6 wk. Bronchiolar epithelium of 6-wk-old animals treated on day 7 was most altered from that of control animals. Almost 100% of the bronchioles were lined by zones of squamous epithelial cells. Compared with control animals, the distal bronchiolar epithelium of 4-ipomeanol-treated animals had more squamous cells (70-90 vs. 0%) with a reduced overall epithelial thickness (25% of control value), fewer ciliated cells (0 vs. 10-20%), a reduced expression of Clara cell markers of differentiation (cytochrome P-4502B, NADPH reductase, and 10-kDa protein), and undifferentiated nonciliated cuboidal cell ultrastructure. We conclude that early injury to differentiating rabbit Clara cells by a cytochrome P-450-mediated toxicant inhibits bronchiolar epithelial differentiation and greatly affects repair.

Abstract
BACKGROUND Hepatic and neurologic injury developed in two infants after ingestion of mint tea. Examination of the mint plants, from which the teas were brewed, indicated that they contained the toxic agent pennyroyal oil. METHODS Sera from each infant were analyzed for the toxic constituents of pennyroyal oil, including pulegone and its metabolite menthofuran. RESULTS Fulminant liver failure with cerebral edema and necrosis developed in the first infant, who died. This infant was positive only for menthofuran (10 ng/mL). In the other infant, who was positive for both pulegone (25 ng/mL) and menthofuran (41 ng/mL), hepatic dysfunction and a severe epileptic encephalopathy developed. CONCLUSION Pennyroyal oil is a highly toxic agent that may cause both hepatic and neurologic injury if ingested. A potential source of pennyroyal oil is certain mint teas mistakenly used as home remedies to treat minor ailments and colic in infants. Physicians should consider pennyroyal oil poisoning as a possible cause of hepatic and neurologic injury in infants, particularly if the infants may have been given home-brewed mint teas.

Abstract
Lesions of natural Helichrysum argyrosphaerum poisoning were studied in eight sheep and one goat. Light microscopic examination revealed widespread, bilaterally symmetrical status spongiosis of the white matter of the brain consistently present in the subependymal area adjacent to the lateral ventricles, cerebellar peduncles, and brain stem in all animals. In three animals, the ultrastructural finding of intramyelinic vacuolation due to splitting of the myelin lamellae at the intraperiod lines indicated myelin edema. There was also mild distension of perivascular and extracellular spaces in the severely affected areas. Significant changes were absent in neurons, glial cells, axons, or blood vessel walls. Myelin edema associated with degeneration and loss of axons and myelin and astrocytic gliosis was present in the intraorbital and intracranial portions of the optic nerves. In the intracanalicular portions of the nerves in three animals that were studied, more chronic lesions consisting of fibrosis and atrophy of the nerve suggested that the optic neuropathy follows compression of the nerve in the optic canal as a result of myelin edema. The toxic principle of the plant also caused a degenerative retinopathy in five animals. The essential histopathologic change was degeneration and loss of the photoreceptor outer segments predominantly in the nontapetal retina. These retinal lesions were associated with hyperplasia and hypertrophy and with migration of the pigmented epithelium, focal retinal separation, and depletion and loss of the nuclear layers.

Abstract
We present a case of acute lethal poisoning by oil of "epazote" (oil of chenopodium), in a 2 y 9 m female. The volatile oil was administered according to the advice of a "curandera" (female healer), in a total quantity of 40 ml. Clinical features of the poisoning were: vomiting, deep coma, seizures, mydriasis, apnea, metabolic acidosis, neurogenic shock and death. The EEG suggested a diffuse encephalopathy, the CT scan with an image of severe brain edema and ventricular collapse. Relevant postmortem findings were brain edema and neuronal necrosis, pneumonia, enteritis, pericholangitis, mild pancreatitis and tubular necrosis. The phytochemical analysis of volatile oil identified ascaridol, the main active compound of the chenopodium herbs, in a quantity of 39 mg/ml (1,560 mg in the dose administered), and Chenopodium graveolens as the plant employed to prepare it. According to the age of the patient, 60 mg of ascaridol would be the recommended dose formerly used in the treatment of parasitic disease. Thus 1,560 mg was 26 times higher than the recommended dose, and exceeded by 56% the dose of 1,000 mg reported as lethal in humans.

Abstract
The experiments on Wistar rats have shown that administration of the hepatotropic poisons tetrachloromethane and polychlorpinene increased an immune response to T-dependent antigens. The combined exposure of the body to the hepatotropic poisons and high ambient temperatures leads to a drastically marked inhibition of immune responses to T-dependent and T-independent antigens. High ambient temperatures enhance a release of a comparatively high-molecular weight immuno-suppressor factor in tetrachloromethane-intoxicated rats, as well as induce production of a comparatively low-molecular weight immunosuppressor factor in the intoxicated rats who retain their splenocytic capacity of generating a low-molecular weight immunostimulating factor. The higher sensitivity retain their splenocytic capacity of generating a low-molecular weight immunostimulating factor. The higher sensitivity of splenocytes from rats with toxic hepatic lesion to elevated ambient temperatures is accounted for by their influence on humoral factors of intoxicated animals' sera.

Abstract
Previous research has demonstrated that 4-ipomeanol toxicosis can enhance the severity of para-influenza virus-induced pneumonia in mice. The objectives of this study were to determine whether calves are susceptible to 4-ipomeanol-induced enhancement of parainfluenza type 3 viral pneumonia and to determine whether 4-ipomeanol alters pulmonary replication of parainfluenza virus. Male Holstein calves were injected with either 4-ipomeanol (3 mg/kg) or vehicle (polyethylene glycol) 3 days prior to intratracheal inoculation with either parainfluenza virus or sham inoculum of culture medium. Calves in the four treatment groups (ipomeanol-parainfluenza, ipomeanol-medium, vehicle-parainfluenza, and vehicle-medium) were necropsied at 5 days after inoculation with parainfluenza virus or medium. The lungs were studied by correlated methods of light and electron microscopy, digitizing morphometry and pulmonary lavage to quantitate the severity of pneumonia. Pulmonary viral titers were determined, and viral antigen was identified in the lung by immunoperoxidase technique. The calves in the ipomeanol-virus treatment group had over a 9-fold higher (P less than 0.05) volume density of virus-induced interstitial pneumonia than did the calves in the other three treatment groups. This 4-ipomeanol-enhanced viral pneumonia was associated with significantly greater (P less than 0.05) numbers of pulmonary macrophages and neutrophils in the lavage fluid and higher (P less than 0.05) pulmonary titers of pulmonary infectious parainfluenza virus. Four-ipomeanol-enhanced viral pneumonia was characterized in part by extensive hyperplasia of type II alveolar epithelial cells and by dense aggregates of macrophages and neutrophils in alveolar spaces and interalveolar septa. The results indicate that 4-ipomeanol exacerbates interstitial pneumonia in calves induced by bovine parainfluenza type 3 virus.

Abstract
The management for ingestion of oil of citronella, an essential oil, has traditionally been rigorous, including dilution with milk or oil, and gastric lavage or emesis, taking care to prevent aspiration. Recently our Centre handled five oil of citronella poisonings and their outcomes led us to review our management protocol which had been based on information from standard poisoning texts. The source data used to determine the human toxicity of oil of citronella and the appropriate management of poisoning included a case report of a fatal ingestion of oil of citronella in a child. On scrutiny, however, the management of this poisoning included now out-moded techniques, giving rise to uncertainties in establishing the true cause of the child's death. Our own experiences indicate that advice given in standard texts based on poisoning cases managed with out-moded techniques should be carefully evaluated.

Abstract
Margosa Oil is an extract of the seed of the Neem tree and is widely used as a traditional medicine by Indians in India, Sri Lanka, Burma, Thailand, Malaysia and Indonesia. Used mainly for external applications, it is often administered orally to neonates and infants regularly in small amounts. Margosa Oil causes toxic encephalopathy particularly in infants and young children. The usual features are vomiting, drowsiness, tachypnea and recurrent generalised seizures. Leucocytosis and metabolic acidosis are significant laboratory findings. Management is aimed primarily towards the control of convulsions although supportive management is equally important. Prognosis is usually good but fatalities and neurological deficits have been reported. We report here two infants with Margosa Oil poisoning presenting with encephalopathy.

Abstract
Fatal acute ethanol intoxication is frequently encountered in medicolegal practice. Although the vast majority of acute ethanol toxicity deaths follow the ingestion of conventional alcoholic beverages, ethanol can be obtained from a variety of commercial products, which often contain high levels of ethyl alcohol but are not manufactured or designed for consumption. Such products may be easily purchased in locales where statutory limitations restrict liquor availability on Sundays or during the early morning hours. Several acute ethanol fatalities have been encountered in New Mexico that were directly related to consumption of non-beverage ethanol-containing products, all of them occurring during times when alcoholic beverage sales were restricted. Despite the fact that manufacturers deliberately include compounds in these products that discourage ingestion, this policy apparently does little to deter individuals who are searching for a source of ethanol when no conventional beverages are available. The products that were consumed in these fatalities also contained other compounds which would be toxic at much greater concentrations, but which were inconsequential in their effects in comparison with the direct toxic effect of ethanol. Investigation of the scene and awareness that alcohol-containing products can be fatally abused are essential to detecting these unconventional ethanol sources.

Abstract
The two objectives of this research were 1) to describe the ultrastructural morphogenesis of pulmonary damage and repair induced in calves after treatment with 4-ipomeanol and 2) to characterize infiltrating pulmonary inflammatory cells by bronchoalveolar lavage. Interstitial edema was observed as early as 4 hours after intravenous injection of 4-ipomeanol (5 mg/kg body weight) and progressed to severe alveolar edema by 72 hours. Damage to type I alveolar epithelial cells and terminal bronchiolar nonciliated cells included dilation of endoplasmic reticulum and perinuclear envelopes and was present at 4 hours after treatment. Necrosis and sloughing of these cells from basement membranes occurred at times from 12 to 96 hours after treatment. Alveolar capillary endothelial cells had mild dilation of endoplasmic reticulum at times from 12 to 72 hours after treatment. Necrosis of endothelial cells was not observed. Inflammatory cell infiltrates in bronchioles and alveoli were dominated by macrophages and neutrophils. Significant elevations (P less than 0.05) in numbers of neutrophils and macrophages were recovered by bronchoalveolar lavage at times from 24 to 96 hours after 4-ipomeanol-treatment. Hyperplasia of nonciliated bronchiolar epithelial cells and of type II alveolar epithelial cells were observed at 72 and 96 hours after treatment. The results indicate that type I alveolar epithelial cells and nonciliated bronchiolar epithelial cells are most susceptible to 4-ipomeanol-induced damage and necrosis in calves. 4-ipomeanol-induced pulmonary edema in calves occurs prior to ultrastructurally-demonstrable, mild, alveolar capillary endothelial cell damage.

Abstract
Acute bracken fern toxicity in a calf was reproduced with ptaquiloside, a norsesquiterpene glucoside, isolated from the boiling water extract of bracken fern. Ptaquiloside was dissolved in 500 ml of saline and administered by drench at increasing dosages for six days out of every seven for the following periods: 400 mg/day for 24 days, 800 mg/day for 14 days and 1600 mg/day for four days. Neutrophilic granulocytes began to decrease markedly around 50 days after the start of the experiment, and granulocytopenia continued for a further 35 days until the autopsy, despite the discontinuance of ptaquiloside administration. Thrombocytes showed a relatively slow depression and reached 1 X 10(5)/mm3 at the lowest level. The calf was autopsied 86 days after the start of administration of ptaquiloside. Sternal bone marrow was found to be mostly replaced with fat marrow and only small foci of erythropoietic cells and a small number of megakaryocytes remained.

Abstract
It was found that in healthy rats cholic acid caused a moderately increased intensity of bile secretion and raised the content of bile acids in it. In animals with toxic hepatitis produced by a long-term action of the chemical poison polychlorpinene in a dose of 1/10 DL50 and following introduction to such rats of cholic acid in a dose of 30 mg/100 g an intensified elinination of cholates and cholesterol excretion were evident. Combined action of polychlorpinene and cholic acid was conductive to a reduced conjugation of cholic acid with taurine and to a greater conjugation with glycine, this being attended by an increased content of free bile acids in the bile.

Abstract
Man's ever increasing exposure to numerous drugs and chemicals, which are the results of medical and industrial progress, produces a by-product of acute toxic nephropathies. These include acute toxic renal failure, drug-induced acute oliguric renal failure, acute hemorrhagic glomerulonephritis, nephrotic syndrome, tubular disturbances and potassium deficiency. In depth information is provided for the previously mentioned disorders.

Abstract
An 18-month-old infant required six hospital admissions in a period of six months for episodes consisting of coughing, respiratory depression, hematemesis, coma, dehydration, and lesions about the mouth. A negative history of ingestion of toxins was repeatedly obtained from the family and two home inspection by the local Health Department failed to identify potential toxins. Metabolic work-up was entirely negative. Utilizing methods of GC-MS, metabolites of a-terpineol were isolated from infant urine on two admissions to the hospital. These metabolites were confirmed by mass spectrometry to be the same metabolites excreted by Sprague-Dawley rats injected with a-terpineol or pine oil. The child had no additional episodes after physical separation from the home environment.

Abstract
Stachybotrys atra cultures grown on oats produced five compounds toxic to brine shrimp; three are the sesquiterpenoid mycotoxins known as 12,13-epoxy-Delta(9)-trichothecenes. One trichothecene is roridin E, a known metabolite of Myrothecium verrucaria. The other two were hydrolyzed to verrucarol, the product of roridin and verrucarin hydrolysis. Spectroscopic data indicate that the two remaining compounds are also 12,13-epoxy-Delta(9)-trichothecenes. These metabolites are probably among those responsible for stachybotryotoxicosis.
