The Great Dane has been found to have a lifetime risk of 42.4% in one study, [10] which has led to the Great Dane being the focus of investigations into causes and risk factors for GDV. [1] One study has found certain alleles of the DLA88 , DRB1 and TLR5 genes, which are part of the canine immune system, to predispose a dog to GDV. [ 13 ]
The person' serum osmolality is measured by freezing point depression and then compared with the predicted osmolality based on the person's measured sodium, glucose, blood urea nitrogen, and any ethanol that may have been ingested. The presence of a large osmolal gap supports a diagnosis of ethylene glycol poisoning.
Some tapeworms have fleas as intermediate hosts: the worm egg must be consumed by a flea to hatch, then the infected flea must be ingested (usually by the dog while grooming itself, but occasionally by a human through various means) for the adult worm to establish itself in the intestines. The worm's eggs then pass in the feces, and the cycle ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
It’s important to know the difference between a toothy grin and a dog on edge. Smiley dogs usually wag their tales in a wide sweeping or circular motion and will approach you or curl their body ...
It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour. Nitrogen dioxide poisoning depends on the duration, frequency, and intensity of exposure.
The gas seaweed releases when it rots — hydrogen sulfide — can irritate your eyes, nose and throat. Tiny sea creatures living in the seaweed, like jellyfish and sea lice, can also cause skin ...
