Deck 2 Flashcards
Two groups of insecticides of which mechanism of action is inhibition of acetylcholinesterase
Organophosphate and carbamate aldicarb
Normal concentration of urea in milk is
2-7 mmol/L
PCB are determined by
Gas chromatography
Advantage of pyretroids
- Human and environmental safety
- High efficiancy - fastest knockdown
- Multi crop - 3000 crops
- Novel node of action - Na+ channel
- Cost effective - 2-5 euro / hectar
- Low dose - 5-15g active ingredient / hectar
- Broad spectrum - chewing and sucking
ANTU is used as
rodenticide
Symptoms of organophosphate intoxication (groups), effect on nervous system
GIT - hypersalivation, abdominal spasms, diarrhea
Respiratory - bronchoconstriction, pulmonary edema, dyspnoea
Heart - bradycardia
Eye - miosis (excessive constriction of pupil)
Effect on nervous system
* Muscarinic - overstimulation of parasympathetic nervous system
* Nicotinic - ganglionic and myoneural junction stimulation (muscle fasciculation & weakness)
* CNS - nervousness, ataxia, apprehension, seizures, depression and convolution
Anticoccidicum monensin is determined by
TLC
Dinitrophenols act by
Inhibition of oxidative phosphorylation
Agents of methemoglobinaemia
Direct acting agents - nitrites, oxidase of nitrogen, potassium fericyanide, sodium chlorate, quinones, methylene-blue in large doses
Indirectly acting agents - aromatic nitro compounds and aromatic amino compounds
Mechanism of action, typical clinical symptoms and therapy of Zn3P2 intoxication
- rodenticide
Mechanism: acts in the acid environment of stomach or in contact with water. PH3 is released –> hydrogen phosphide poisoning
Clinical symptoms: abdominal pain, gas (tymphani of GIT), apathy, rigidity, vomiting, staggered moving, spasms and death (at high concentration)
Therapy: immediately after - gastric lavage, solution of copper sulphate or potassium permanganate
The characteristic clinical signs of DNOC poisoning
Ethiology: insecticide, herbicide and fungicide
Symptoms:
Yellow mucus membranes, skin and feathers. Hyperpnoea, dyspnoea, sweating, oliguria, muscle weakness, increased body temperature, spasms, rapid rigor mortis after death
The principal constituent of opium (10%) is
morphine
Treatment of urea intoxication includes the administration of
acetic acid, vinegar and hydrochloric acid
Ergotism is
a disease of farm animals that results from continuous ingestion of parasitic fungus - claviceps purpurea
Herbicide sodium chlorate causes when absorbed:
production of methemoglobin
