An experimental model of peripheral neuropathy induced in rats by Karwinskia humboldtiana (buckthorn) fruit.

Intoxication by Karwinskia humboldtiana (buckthorn) fruit presents a neurological picture similar to that of Guillain-Barré syndrome. In this report, we describe an experimental animal model of peripheral neuropathy induced by buckthorn fruit. Four groups of Wistar rats received one oral dose of 1.

Quantitative analysis of liver peroxisomes in rats intoxicated with peroxisomicine-A1.

Peroxisomes are single-membrane-bound organelles present in almost all eukaryotic cells. Hypolipidemic agents such as clofibrate, herbicides and plasticizers induce an increase in the number and size of peroxisomes from mammalian cells. However, there is no evidence of drugs causing a decrease in the number of these organelles.

[The incidence of poisoning by Karwinskia humboldtiana in Mexico].

Intoxication produced by Karwinskia humboldtiana presents a neurological picture similar to that of poliomyelitis, Guillain-Barré syndrome or other polyradiculoneuritis with which it is frequently confused. The purpose of this paper is to report the frequency of this intoxication, by means of the antecedent of ingestion of the fruit and the detection of toxins in blood using a thin layer chromatography method. One hundred fifty four samples of cases with acute flaccid paralysis from 18 states of the country were received.
