Epinephrine-induced hyperuricemia in experimental animals.

Epinephrine-induced pulmonary edema in crosscirculated animals.

Blood with epinephrine was infused into crosscirculated dogs and comparison was made between animals receiving the infusion only in their heads, only in their trunks, or in their entire circulation. The procedure was invariably followed by pulmonary edema in all experimental animals. Left ventricular systolic pressure elevations and increases of the dp/dt of this chamber were similar in all ani...

Scorpion Venom Pisoning in Experimental Animals

Bidder's organ extract induced anaphylaxis in experimental animals.

Bidder's organ (BO, a vestigeal organ), present in toad Bufo melanostictus (Schenider), is a characteristic feature of all male bufo. Its possible anaphylactic properties are investigated on experimental animals. BO extract produced both in vivo and in vitro anaphylactic reaction in guineapig. Dyspnoea and bronchoconstriction was a major cause of anaphylactic death. Blood histamine level was si...

Metal-Induced Oxidative Stress and Cellular Signaling Alteration in Animals

Contamination by heavy metals has attracted increasing attention considering the ability of these elements in producing serious consequence to ecosystem, and especially on animals health. Due to their widespread use in human activities such as industry, agriculture and even as medicine (e.g. arsenic, selenium and platinum), numerous health risks may be associated with exposure to these substanc...

Induced Termination of Pregnancy in Domestic Farm Animals

Induced abortion may be desired during a normal or abnormal pregnancy. The methods of induced abortion differ between species mainly because of different sources for progesterone production during pregnancy between species and within a species according to different stages of gestation. In cows and buffaloes, pregnancy can be effectively terminated from 5 to 150 days by administration of luteol...
