This complete laboratory reference manual explains the principles behind solid phase extraction (SPE) and provides readily reproducible protocols for solving extraction problems in forensic and clinical chemistry. Numerous actual chromatograms, based on original research and diverse applications, demonstrate the technique and the results that can be achieved. Extensive appendices allow fast access to frequently needed information on reagents, the preparation of solutions and buffers, milliequivalent and millimode calculations, buffers and pKa for SPE, and a complete RapidTrace(r) technical...

It is at least a decade since scientists turned their imaginations to creating new compact, portable test instruments and self-contained test kits that could be used to analyze urine and saliva for alcohol, drugs, and their metabolites. Although the potential applications for such tests at the site of specimen collection, now called on-site or point-of-care testing, range far beyond hospital emergency rooms and law enforcement needs, it was catalyzed by the requirements of workplace drug testing and other drugs-of-abuse testing programs. These programs are now a minor national industry in the...

Prominent experts explain the pharmacology and metabolism of benzodiazepines (LDB) and g-hydroxybutyric acid (GHB) and offer powerful and effective methodologies that will enable better detection of these drugs in various body fluids, as well as in hair. The techniques include highly sensitive immunoassay detection of LDBs, the detection of Rohypnol(r) and other LDBs by mass spectrometry, and the ultrasensitive detection of GHB. State-of-the-art and highly practical, Benzodiazepines and GHB: Detection and Pharmacology offers toxicologists, forensic scientists, and clinical chemists today's...

A treasure trove of uncommon and reliable scientific and clinical information for the toxicity and usefulness of today's leading nonherbal dietary supplements. The supplements detailed were chosen for their popularity, toxicity, and the quantity and quality of information available. Each monograph discusses the history of the compound; its chemical structure; its current and promoted uses, sources, and chemical composition; and its toxicity, pharmacokinetics, and physiological role. Also presented are case reports of adverse effects and interactions, as well as information on reproductive...

In Buprenorphine Therapy of Opiate Addiction, participating physicians and toxicologists summarize and evaluate their experiences with five years of intensive buprenorphine therapy. They cover all aspects of its use, including the pharmacology, conditions of delivery, risks from use with other psychoactive drugs, toxicology and related deaths, as well as its testing in blood, urine, tissue, and hair. Special attention is given to comparing the long-term care of opiate-dependent patients using high-dose buprenorphine vs methadone, and to explaining the differences in treatment, administration,...

A concise compilation of the known interactions of the most commonly prescribed drugs, as well as their interaction with nonprescription compounds. The agents covered include CNS drugs, cardiovascular drugs, antibiotics, and NSAIDs. For each class of drugs the authors review the pharmacology, pharmacodynamics, pharmacokinetics, chemistry, metabolism, epidemiological occurrences, adverse reactions, and significant interactions. Environmental and social pharmacological issues are also addressed in chapters on food and alcohol drug interactions, nicotine and tobacco, and anabolic doping agents....

Publius Syrus stated back in 42 B.C., You cannot put the same shoe on every foot. (Maxim 596) Though written long before the advent of forensic science, Syrus maxim summarizes the theme of Forensic Medicine of the Lower Extremity: Human Identification and Trauma Analysis of the Thigh, Leg, and Foot. Put simply, the lower extremity is a tremendously variable anatomic region. This variation is beneficial to forensic experts. Differences in the leg and foot can be used to establish individual identity. Analysis of damage to the lower limb can be used to reconstruct antemortem, perimortem, and...

A comprehensive review of the science of drug testing in all its aspects, placing emphasis on technologies that use body fluids other than urine for determining the presence of drugs of abuse. The authors discuss the various body fluid specimens suitable for testing for illicit drugs-particularly saliva, sweat, and hair-describe the structural and manufacturing aspects of on-site testing devices based on lateral flow immunoassay, and detail the pitfalls of using these specimens. They also discuss in detail the problem of sample adulteration and its detection. Since oral fluid has the best...

Although primarily used today as one of the most prevalent illicit leisure drugs, the use of Cannabis sativa L., commonly referred to as marijuana, for medicinal purposes has been reported for more than 5000 years. Marijuana use has been shown to create numerous health problems, and, consequently, the expanding use beyond medical purposes into recreational use (abuse) resulted in control of the drug through international treaties. Much research has been carried out over the past few decades following the identification of the chemical structure of THC in 1964. The purpose of Marijuana and the...
