The fungicide blasticidin S has been used against a rice blast disease. Reports on its human toxicity are extremely limited, and irritation to GI tract, eye and skin are the presenting symptoms in most afflicted cases. Fatalities resulting from profuse intestinal fluid loss with subsequent
Acute ingestion of copper sulfate has been reported to cause gastrointestinal injury, hemolysis, methemoglobinemia, hepatorenal failure, shock; or even death. The toxicity of organocopper compounds, however, remains largely unknown. A 40-y-old man attempted suicide by ingesting some 50 ml of
Acute oral toxicity of the copper fungicides, copper sulphate and copper oxychloride, were studied in male Gallus domesticus. The median lethal dose for copper sulphate and copper oxychloride determined were 693 and 1263 mg/kg body weight, respectively. Severe diarrhea and delayed mortality (3 to 6
I believe there are four essential elements in the management of patients with irritable bowel syndrome (IBS): to establish a good physician-patient relationship; to educate patients about their condition; to emphasize the excellent prognosis and benign nature of the illness; and to employ
Headache makes one of the most common side effects of frequently pesticide application. This is to be taken care of in rural areas. Headaches have been reported with the use of ivermectin, ivermectin-diethylcarbamazine, organophosphates, and also with the fungicide maneb and copper sulfate,
These agents act as anticholinesterases. Signs of toxicity are: overactivity of the parasympathetic nervous system, nausea, vomiting, diarrhea, sweating, abdominal cramps and copious secretions. Large doses may cause sustained depolarization of the motor end plate, leading to muscular paralysis.
Pyraclostrobin is a strobilurin fungicide that inhibits mitochondrial complex III of fungal and mammalian cells. In toxicity studies that were used to estimate the safety factor, pyraclostrobin was added to animal feed or to aqueous vehicles. However, foods containing residues of pyraclostrobin and
The cell free culture filtrate of a Comamonas testosteroni associated with an Entomopathogenic nematode (EPN), Rhabditis (Oscheius) sp. exhibited promising antimicrobial activity. The ethyl acetate extract of the bacterial culture filtrate was purified by silica gel column chromatography to obtain
Pesticides are used extensively throughout the world in agriculture and in pest control as well as for community health purposes. Organophosphate (OP) pesticide self-poisoning is an important clinical problem in rural regions of the developing world that kills an estimated 200,000 people every year.
Arsenicals in agriculture. Beginning in the 1970s, the use of arsenic compounds for such purposes as wood preservatives, began to grow. By 1980, in the USA, 70% of arsenic had been consumed for the production of wood preservatives. This practice was later stopped, due to the US Environmental
