Minimal reports are available on the relationship between blood lipids such as cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) and acne. Most of available literature was about the effect of drugs used in acne treatment on these parameters. In this work we determined plasma total cholesterol, triglycerides, HDL-C and LDL-C levels in 166 (83 males and 83 females) newly diagnosed untreated Jordanian acne patients and compared with 105 (52 males and 53 females) of age and sex matched healthy controls. Results indicated that acne patients, males and females, had significantly low plasma HDL-C levels (p=0.000). Plasma total cholesterol, triglycerides and LDL-C levels were shown to be within the normal range except for triglycerides and LDL-C levels in severe acne cases for both sexes, were shown to be significantly elevated compared with those in healthy controls (p=0.004 and 0.000 consequently). It has been noticed that there was a trend for plasma HDL-C of acne patients to decrease as the severity of acne condition increases. Our results indicated that acne patients have significant changes in the plasma lipids profile that should be considered in the pathogenesis as well as in the treatment of acne.

The concentrations of chlorate and perchlorate were examined by ion chromatography-tandem mass spectrometry (IC-MS-MS) in 106 bottled beverages purchased or obtained mainly in the Tokyo area to estimate exposure to these chemicals attributable to bottled beverages. The bottled beverages were classified into 5 categories: water from the water supply (n=5), natural water (n=49), bottled water (n=10), tea (n=25), and soft drinks (n=17). Chlorate was detected in 85 bottled beverages (highest concentration, 700 μg/l), including all of the samples of bottled water from the water supply at levels ranging from 25 to 120 μg/l. Perchlorate was detected above the minimum reporting limit (i.e., 0.05 μg/l) from 62 bottled beverages, with the highest concentration of 0.92 μg/l. As the average consumption of bottled beverages calculated from market statistics is approximately 400 ml/day per person, it seems important to take the amounts of chlorate and perchlorate ingested from bottled beverages into consideration for estimation of total intake of these chemicals.

The effects of repeatedly brewed green tea infusion on the formation of nitrosamine in vitro and in vivo, and on cancer mortality were examined. The first and second brews of green tea infusion inhibited the formation of nitrosomorpholine in the presence of morpholine and nitrite (nitrosation of morpholine), but the third to eighth brews accelerated it. The green tea infusion brewed from 5 g of leaves in 200 ml hot water (strong tea infusion) inhibited the nitrosation of morpholine, but that brewed from 2.5 g or less (weak tea infusion) promoted the nitrosation. The brewed green tea infusion that inhibited nitrosation of morpholine contained catechins at a high concentration, and that that promoted nitrosation contained catechins at a low concentration. The effects of green tea administered to Wistar male rats and that consumed by humans on the formation of nitrosamines were also examined. In both rats and humans, nitrosamine formation was inhibited by strong green tea extract but was increased by weak green tea extract. The concentration of catechins in the green tea infusion brewed by the general households in tea-producing areas was significantly higher than that brewed in non-producing areas. We examined the relationship between the concentration of catechins in green tea infusion brewed in different areas and the standardized mortality ratio (SMR) of cancer in respective areas, and found that the catechin concentration in green tea infusion correlated inversely and significantly with the SMR of cancer in that area. We concluded that strong green tea might inhibit the formation of nitrosamines and decrease the risk of carcinogenesis.

One of the urgent tasks in understanding endocrine disruptors (EDs) is to compile a list of suspected substances among the huge number of chemicals by using the screening test method. We developed a simple and rapid screening method using the yeast two-hybrid system based on the ligand-dependent interaction of nuclear hormone receptors with coactivators. To date, we have tested the estrogenic activity of more than 500 chemicals including natural substances, medicines, pesticides, and industrial chemicals. 64 compounds were evaluated as positive, and most of these demonstrated a common structure; phenol with a hydrophobic moiety at the para-position without bulky groups at the ortho-position. These results are expected to facilitate further risk assessment of chemicals.

The cultivation or trafficking of "Magic mushrooms," containing hallucinogenic psilocin and psilocybin, has been prohibited by the Narcotics and Psychotropics Control Law in Japan since 2002. To identify these mushrooms, we attempted to prepare the monoclonal antibody (mAb) reactive to these hallucinogens. As an antigen inducing an anti-psilocin mAb, N-{4-[3-(2-dimethylaminoethyl)indol-4-yl-oxy]butyl}succinamic acid was synthesized by modifying the 4-hydroxyl moiety of psilocin and coupled to a carrier protein of keyhole limpet hemocyanin. BALB/c mice were immunized five times with the antigen emulsified with an adjuvant, and their spleen cells were fused with mouse myeloma cells. We obtained several hybridoma cells producing mAbs reactive to psilocin, from which fourclones, BA631, CA231, KA422, and MA332 with a higher production of anti-psilocin mAb were selected by limiting dilution. Isotype of CA231 and KA422 mAbs were IgG2a and that of BA631 and MA332 mAbs were IgGl.Enzyme immunoassay (EIA) using BA631 mAb, revealed that BA631 cross-reacted with psilocin and dimethyltryptamine, but not with the other indole derivatives such as psilocybin, 4-hydroxyindole, tryptamine, and tryptophan. Therefore, these antibodies could be used for the identification of magic mushrooms.

The inhabitants living in a specific region of Kizaki area in Kamisu-town, Ibaraki Prefecture exhibited uncommon clinical central nervous system symptoms. A graphite furnace atomic absorption spectrophotometer detected markedly elevated concentration of arsenic (4.5 ppm) in their drinking well water. Further investigation using HPLC, GC/MS and HPLC/ICP/MS demonstrated that the structures of the arsenic were bis(diphenylarsine)oxide (BDPAO), diphenylarsinic acid (DPAA) and phenylarsonic acid (PAA), compounds that can be derived from the chemical warfare agents, diphenylchloroarsine (DA) and diphenylcyanoarsine (DC). The predominant form of the arsenic compound in the well water was DPAA (maximum 15 ppm), so that it was calculated that the inhabitants ingested 11-30 mg of DPAA daily. This is the first report of inhabitants that were injured by drinking well water contaminated with organic arsenic compounds that were likely derived from chemical weapons.
