HP-beta-CD has been shown to be well tolerated in humans, with the main adverse event being diarrhoea and there have been no adverse events on kidney function, documented to date. There were no effects on embryo-foetal development in either rats or rabbits. There were also non-carcinogenic changes noted in the urinary tract, but these changes were also reversible and did not impair renal function. ![]() The carcinogenicity studies showed an increase in tumours in rats in the pancreas and intestines which are both considered to be rat-specific. When dosed intravenously, histopathological changes were seen in the lungs, liver and kidney but all findings were reversible and no effect levels were achieved. In short duration studies, there were slight biochemical changes whereas studies of a longer duration, up to three months, produced additional minor haematological changes but no histopathological changes. This review concludes that HP-beta-CD is well tolerated in the animal species tested (rats, mice and dogs), particularly when dosed orally, and shows only limited toxicity. In addition, it includes a brief review from studies of the metabolism and pharmacokinetics of HP-beta-CD in both humans and animals. This paper reviews the toxicity of HP-beta-CD, using both literature information and novel data, and presents new information. Also, liver failure can occur two to three days after a dog ingests some of the sago palm. ![]() Pancreatitis in humans has also been reported after accidental insecticide exposure.2-Hydroxylpropyl-beta-cyclodextrin (HP-beta-CD) is an alternative to alpha-, beta- and gamma-cyclodextrin, with improved water solubility and may be more toxicologically benign. Signs of toxicity such as vomiting, diarrhea, and drooling can be seen anywhere from 15 minutes to a couple of hours after ingestion of the sago palm by a dog. The insecticide pancreatitis model is considered a simple, non-invasive, reproducible, and cheap and useful method to evaluate early changes and methods of treatment in acute pancreatitis. It was concluded that inhibition of pancreatic BuChe leads to cholinergic hyperstimulation of the acinar cell, which results in acute pancreatitis, and that pancreatic BuChE is essential for dogs and guinea pigs to downregulate cholinergic excitation. Even one raisin or grape can be enough to harm your dog. Acute kidney injury can be very expensive to treat and requires intensive veterinary care. ![]() Digesting these substances can result in gastrointestinal symptoms such as diarrhea, loss of appetite, and vomiting. If your dog eats a raisin or grape there is a high chance that the toxin found in the fruit will cause harm to the dog’s kidneys resulting in kidney failure. ![]() Atropine pretreatment (0.2 mg/kg) gave complete protection against pancreatitis. Garbage, lead paint, English ivy, English holly, chocolate, medications, poinsettia, iris, Chinaberry, daphne, and pokeweed are dangerous to dogs. In cats, which lack pancreatic BuChE, no pathological changes occurred after two, three, and six hours, whereas in the guinea pigs as in dogs, both having abundant pancreatic BuChE, vacuolization of the acinar cells, interstitial edema and vasculitis indicate acute edematous pancreatitis as early as two hours. It’s worth noting, the average amount of time that it takes for symptoms of poisoning to show up is three to four days. Cataracts can occur in animals with chronic dinitrophenol intoxication. Clinical signs include fever, dyspnea, acidosis, tachycardia, and convulsions, followed by coma and death with a rapid onset of rigor mortis. A recent study found that dogs exposed to lawn care chemicals can have a higher bladder cancer risk. To further evaluate this theory, we exposed dogs, cats, and guinea pigs to a single sublethal dose of the organophosphate insecticide Diazinon (75 mg/kg). Dinitrophenolic herbicides markedly increase oxygen consumption and deplete glycogen reserves. Based on histochemical examination of the acinar tissue, it was suggested that pancreatic tissue-fixed butyrylcholinesterase (BuChE) is the target enzyme of organophosphate toxicity. The organophosphate insecticide Diazinon has been reported to cause acute pancreatitis in dogs.
