Spontaneous poisoning by Sida carpinifolia (Malvaceae) in horses

Use of lectin histochemistry to diagnose Sida carpinifolia (Malvaceae) poisoning in sheep.

by standard histological methods and stained with haematoxylin and eosin. Microscopically, there was distension and vacuolation of Purkinje cells in the cerebellum (Fig 1) and of neurons in the cerebral cortex, thalamus, mesencephalon and spinal cord. Cytoplasmic vacuolation was also present in the epithelium of the pancreatic acinus and renal tubules, follicular epithelium of the thyroid, in h...

Locoweed Poisoning of Horses

programs. INTRODUCTION Locoweed has been reported to be the most widespread poisonous plant problem in the Western United States. It has a substantial economic impact, and may be responsible for the loss of more than $300 million in annual income due to deaths of poisoned livestock. The major contributors to these poisonings are plants from the Astragalus (Figure 1) and Oxytropis (Figure 2) gen...

Secondary metabolites from Sida rhombifolia L. (Malvaceae) and the vasorelaxant activity of cryptolepinone.

The phytochemical study of Sida rhombifolia L. (Malvaceae) led to the isolation through chromatographic techniques of eleven secondary metabolites: sitosterol (1a) and stigmasterol (1b), sitosterol-3-O-b-D-glucopyranoside (2a) and stigmasterol-3-O-b-D-glucopyranoside (2b), phaeophytin A (3), 17³-ethoxypheophorbide A (4), 13²-hydroxy phaeophytin B (5), 17³-ethoxypheophorbide B (6), 5,7-dihydroxy...

The hematology of phenothiazine poisoning in horses.

Alkaloids and Phenolic Compounds from Sida rhombifolia L. (Malvaceae) and Vasorelaxant Activity of Two Indoquinoline Alkaloids.

The follow-up of phytochemical and pharmacological studies of Sida rhombifolia L. (Malvaceae) aims to strengthen the chemosystematics and pharmacology of Sida genera and support the ethnopharmacological use of this species as hypotensive herb. The present work reports phytoconstituents isolated and identified from aerial parts of S. rhombifolia by using chromatographic and spectroscopic methods...
