Suicide by intravenous injection of a veterinary euthanasia agent: report of a case and toxicologic studies.

Previously reported cases of suicide by intravenous barbiturates, as well as two other unusual cases [5,6], are compared in Table 2. All decedents were either medical or paramedical personnel and familiar with the drugs and the routes of administration used for their suicides. Lethal is used in veterinary euthanasia at an intravenous dose of 1 ml per 5 kg (10 lbs) body weight. Unconsciousness usually occurs during injection and death supervenes within a matter of seconds. The decedent in the present case weighed 90 kg (200 lbs) and had injected at least 40 ml of the drug, approximately twice the recommended lethal dose. There appears to be little doubt of the victim's suicidal intent, since he had used Lethal in his daily occupational duties. Additionally, the physical configuration of the supports devised to hold the syringe was quite stable, and injection stopped only when the decedent's hand came to rest upon the towels. To our knowledge, the present case represents the only one of its kind in the literature.

A quantitative approach to epidermal wound healing: the effect of dexamethasone on regenerating epithelium.

The effect of dexamethasone on the regeneration of new epithelium over the base of an excised suction blister has been studied over a period of 9 days. It was found that dexamethasone did not significantly affect the migration of epidermis over the blister base but it did significantly reduce the number of cells in DNA synthesis and post wounding acanthosis of wound edge and regenerating epithelium.

The effect of intracutaneous injections of micronized crystalline suspensions of nandrolone phenyl-propionate in the skin of female hairless hamsters.

Single intracutaneous injections of micronized crystalline suspensions of nandrolone phenylpro-pionate have been shown to induce local thickening of the epidermis of female hairless hamsters, accompanied by a marked increase in sebaceous gland volume over a period of 7 days. It is known that certain materials, when injected intracutaneously, may produce a diffuse inflammatory response in the dermis which in turn causes hyperplasia in the adjacent epidermis. The response observed in the present case, however, is clearly specific to nandrolone phenylpropionate, and cannot be attributed to an inflammatory response of the dermis to intracutaneously injected crystalline material.
