Impacts of Persian Gulf blackfin stonefish crude venom on the haematological factors and serum enzymes levels of laboratory rat

Background: One of the venomous fishes of Persian Gulf is a type of stonefish called blackfin stonefish (Pseudosynanceia melanostigma) that is very poorly-known. This fish lives on the muddy bottoms of marine shallow waters and have venomous spines on its stone like body. The envenomation usually is happened by unwanted contact of human body to its body and the proteinic venom is injected into the skin. Upon the venom entrance to the body various symptoms and signs will occur that their intensity depends on the venom amount.The aim of study is the understanding of some pharmacological impacts of blackfin stonefish for future studies. Material and Methods: A total of 18 male laboratory rats were divided into three groups of control, second and third and envenomed by sub lethal doses (1/3 LD50 and ½ LD50) intravenously and the serum enzymes namely Creatine Phosphokinase, Lactate Dehydrogenase, Glutamate-Oxaloacetate Transaminase, Gamma-Glutamyl Transpeptidase , Alkaline Phosphatase and Amylase, serum electrolytes namely Sodium. Potassium and Calcium and also complete blood cells of control and experimental rats were measured. Results: The serum enzymes levels, potassium and calcium levels and withe blood cells count in envenomed rats by blackfin stonefish crude venom in compare with control rats had significant increase while the haemoglobin level, red blood cells count and also serum sodium level had significant decrease (p
