Drugs, 1987
Spermatogenesis is a complex process which takes about 70 days in the human. Its endocrine control may be affected by various hormones, antihormones or psychotrophic drugs. Cytotoxic agents, or industrial chemicals such as dibromochloropropane, directly affect the germinal epithelium.

Nature, 1948
IN previous work from this laboratory it has been established that the polymerization of actin is influenced by various ions in different ways. In view of the possibility that the change of globular actin into fibrous actin plays an important part in the mechanism of muscle contraction, it is especially interesting that calcium and potassium (or sodium)

Abstract Drugs can increase nutrient requirements through various mechanisms and if these requirements are not met by dietary modification or provision of nutrient supplements, deficiency disease will result. Commoner nutritional effects of drugs consist in the insidious development of hypovitaminoses; other serious nutritional consequences of drug ...

The Effects of Drugs on Thermoregulation
AACN Clinical Issues: Advanced Practice in Acute and Critical Care, 2004Body temperature is a balance of the hypothalamic set point, neurotransmitter action, generation of body heat, and dissipation of heat. Drugs affect body temperature by different mechanisms. Antipyretics lower body temperature when the body's thermoregulatory set point has been raised by endogenous or exogenous pyrogens.

Ophthalmological Side-Effects Of Drugs
Acta Clinica Belgica, 1976The opthalmological side effects of oral contraceptives (OCs) among many other drugs are reviewed. Among these effects are cerebrovascular accidents with secondary phenomena (homonymous hemianopsia or quadranopsia and diplopia) occurring in 50-6-% of the cases.

Drug effects on spermatogenesis
Drugs of Today, 2007Many drugs can adversely affect spermatogenesis. These effects can occur either by directly inhibiting sperm or testicular function or indirectly by impairing the hypothalamic pituitary testicular axis. In this paper, we will review the drugs that are known to adversely impact spermatogenesis, and/or sperm function and detail what is known about the ...

Journal of Clinical Neurophysiology, 2006
Although excess beta activity and a mild theta increase may be the most common EEG alterations associated with medication, more remarkable changes may also appear. Although changes such as diffuse delta, triphasic waves, bisynchronous spikes or polyspikes, burst suppression or electrocerebral inactivity may indicate a dismal prognosis under many ...

Drugs that bind readily to a tissue may differ markedly in their ability to produce an effect. In other words, they differ in efficacy or in intrinsic activity. We do not know the reason for these differences; in fact, we do not know very much about the sequence of events between binding and effect.

Pediatrics In Review, 1991
The tragic consequences for the fetuses of pregnant women using the sedative thalidomide destroyed the theory that the placenta was a type of barrier protecting the fetus from the effects of maternal pharmacology. It now is known that virtually all drugs and chemical compounds cross the placenta. Because such compounds have to cross several lipoprotein

Drug Interactions: Effects of Drugs and Chemicals on Drug Metabolism
Gastroenterology, 1964Summary The rate of metabolism of drugs by certain hepatic enzymes can be decreased or increased. These changes in drug metabolism can occur rapidly or be delayed in onset, and can be of short duration or be maintained for several months. There is no good way to predict what will cause these changes in drug metabolism.
