THE TOXIC ACTION OF BELLADONNA PLASTER.

The Toxic Action of Copper on Nitella

1. Using the loss of turgidity of the cells as a criterion it is found that the toxicity curve of copper chloride with Nitella is sigmoid. An empirical equation can be constructed which will approximately fit the curve. 2. When the concentration of the copper chloride is varied the toxic effect varies as a constant, fractional, power of the concentration. This relation holds when the concentrat...

Anticholinergic Toxic Syndrome Caused by Atropa Belladonna Fruit (Deadly Nightshade): A Case Report.

Atropa Belladonna poisoning may lead to anticholinergic syndrome. Ingestion of high amounts of the plant may cause lethargy, coma, and even a serious clinical picture leading to death. In this case report, we aimed to present a case with anticholinergic syndrome that developed after ingestion of the fruit called "Deadly Nightshade" in our country.

Belladonna Poisoning

Recently, a patient, aged 35 years, attended the out-patients' department one morning for swelling and pain of the right side of the scrotum of a couple of days' duration. There was no history of any venereal disease. There was a history, however, of a similar previous enlargement, two or three times years ago. The patient kept up a slight temperature. Bowels?constipated. Urine?normal. Diagnosi...

Modes of action of toxic agents.

The principal modes of action of toxic agents are discussed in relation to the type of chemical bond formed between the poison and the target constituent of tissues. Alteration of enzyme activity, interference with the binding of poisonous chemicals to proteins, intercalation with nucleic acids, disturbances in electrolyte balance and the disorganization of cellular water and membrane lipids ar...
