In /rat/ urine, the following substances were identified and quantified by GC peak areas: unchanged 1,6-dimethylnaphthalene, 1-methyl-hydroxynaphthalenes, 1-hydroxymethyl-6-methylnaphthalene, 1,6-dimethyl-thionaphthalene, 6-methyl-1-naphthoic aldehyde, 6-methyl-1-naphthoic acid, 1,6-dimethyl-thionaphthalene and 1,6-dimethyl-methylthionaphthalene.
80 male and female young adult golden Syrian hamsters were divided into groups. Group A was the control group. Groups B, C, and D were treated by painting of the left buccal pouch 3 times/wk with a 0.5% solution of 7,12-dimethylbenz(a)anthracene in heavy mineral oil. Group C was painted with mineral oil containing 0.3% 1,4-dimethylnaphthalene. This group showed intermediate tumor numbers and sizes. Apparently 1,4-dimethylnaphthalene retards development of epidermoid carcinomas in hamster buccal pouches induced by 7,12-dimethylbenz(a)anthracene. /1,4-Dimethylnaphthalene/
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . /Naphthalene and Related Compounds/
Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Start an IV with lactated Ringer's. Adequate hydration must be maintained to prevent renal failure secondary to myoglobinuria unless signs of cerebral or pulmonary edema are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. ... . Treat seizures with diazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Naphthalene and related compounds/

The distribution, excretion and metabolism of 1,6-dimethylnaphthalene following i.p. administration of a single dose of 20 mg/kg to rats, was investigated using radiotracer (3H) and a gas chromatography-mass spectrometry technique (GC-MS). After 72 hr, about 94% of the given dose was excreted in urine and feces. In organs and tissues, the highest concentration during the first hours after administration was detected in fat, liver, spleen and kidneys. Then gradual decline of tritium was noticed in all examined tissues.

In order to perform the analysis of the components contained in fossil fuels, carbon assignments of new methylated derivatives of tetralin and indan were obtained. Their chemical shifts were calculated by applying additivity rules.
infection, cancer, leukemia, and rheumatoid arthritis. With the aim of enhancing the binding affinity and anti-HIV activity of a potent CXCR4ligand as a lead, 23 low molecular weight compounds containing dipicolylamine (Dpa) and cyclam cationic moieties with varying spacers and spatial positioning were designed, synthesized and biologically evaluated. All of the synthesized compounds screened at 1.0 μM

Synthesis and redox potentials of methylated vitamin K derivatives
We report the synthesis of derivatives of vitamin K3 as well as of vitaminsK1 and K2 containing a different number of methyl groups in various positions in order to reduce their redox potentials and to change systematically their steric features. The long aliphatic chain of vitaminsK1 and K2 is simulated by an undecyl chain or a methyl group, respectively. The redox potentials of the first reduction
