The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a fluid that circulates in the vessels and intercellular spaces of many invertebrates with an open system of blood circulation, such as arthropods and mollusks.

Hemolymph performs the same functions as blood and lymph in animals with a closed circulatory system (some worms, vertebrates). It transports oxygen and carbon dioxide, nutrients, and secretory products. It is rich in organic substances, including proteins, and frequently contains the respiratory pigments hemocyanin and hemoglobin. Hemolymph also contains cellular elements of various structure and function (phagocytes, excretory cells, and, in some cases, erythrocytes).

The activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and the concentrations of cholesterol (CHO), triacylglycerol (TG), hemolymph urea nitrogen (HUN), and total protein (TP) were measured in a clinical laboratory of the First Affiliated Hospital of Sun Yat-sen University using an automatic biochemical analyzer (Hitachi 7170; DAICHI, Tokyo, Japan) within 2 days.
Mantle cavity injection was chosen instead of intramuscular injection to allow the antibiotics to reach the gastrointestinal tract through the filtration and feeding path rather than reaching the circulatory system through the hemolymph. The assay was repeated three times.
Given that the mantle region is one of the main storage sites of glycogen in terrestrial gastropods, the hemolymph that supplies this area is rich in glucose (Pinheiro, 2007).
The present study was undertaken to determine the influence of GA3 on the hemolymph content of the greater wax moth, G.
The appearance of SFTSV in saliva and hemolymph suggests that the virus circulates in the tick hemocoel and is expressed in saliva.
Recovery assays were performed for rotenone using standards to reach 0.5, 1.0, and 2.0 mg/kg concentrations in midgut, brain, ventral nerve cord, hemolymph, and excreta.
It thus appears that there may be multiple sites for ascidian blood (hemolymph) production, in particular in colonial tunicates.
In other crustacean, antioxidant status has also been investigated in the hemolymph of brachyuran crabs which is known as Liagore rubromaculata [19].
Quantitative realtime PCR was used to analyze the expression characteristics of BmLeb5 in the whole larvae, in the fat body, and in hemolymph at different periods after B.
We have also seen a proliferation of hemocytes, accumulation and cell grouping in treated insects which induced some semblance coagulation of the hemolymph in Locusta migratoria, in contrast to what was observed by Halouane [5] who tested Metharhizium anisopliae on Shistocerca gregaria and Adama Coulibaly [3] have tested the effect of Beauveria bassiana and Metharhizium flavoviride on Anacridium aegeptium and noted a decrease in the concentration of hemocytes.
Aquatic larvae of dipterous genera, such as Aedes and Chironomus, have developed anal papillae that absorb sodium and chloride ions into the hemolymph (Stobbart 1960; Wright 1975).
