The purpose of this study was to examine the acute and sub-acute effects of diazinon onhistopathological parameters of liver tissue and blood level of hepatic enzymes of male commonfrog (Rana ridibunda). Frogs were assigned to 9 groups (n=8, meaning 8 frogs in each group):control and treatment groups with 30, 60, 90 and 120 μg/L diazinon in water for one day or oneweek. Hepatic enzymes containi...

We have recently shown that corticotropin-releasing hormone (CRH) is a major thyrotropin (TSH)-releasing factor in amphibians, but we have also found that, besides CRH, other hypothalamic substances stimulate TSH secretion in frog. In order to characterize novel TSH secretagogues, we have investigated the effect of frog (Rana ridibunda) vasoactive intestinal polypeptide (VIP) (fVIP) and pituita...

Simultaneous use of parasitoids and entomopathogenic nematodes for codling moth (CM) control could produce an antagonistic interaction between the two groups resulting in death of the parasitoid larvae. Two ectoparasitic ichneumonid species, Mastrus ridibundus and Liotryphon caudatus, imported for classical biological control of cocooned CM larvae were studied regarding their interactions with ...

The intermediate lobe of the pituitary gland synthesizes a glycoprotein, proopiomelanocortin (POMC), which is cleaved by specific proteolytic enzymes to generate several hormonal peptides. The purpose of the present study was to examine the possible role of the carbohydrate moiety in the synthesis, intracellular processing and release of POMC-derived peptides in frog (Rana ridibunda) intermedia...

BACKGROUND Frog skin secretions have potentials against a wide spectrum of bacteria. Also, frog skin compositions have healing properties. OBJECTIVES The aim of this study was to investigate the antibacterial potentials along with healing properties of frog skin Rana ridibunda, a species which thoroughly lives in Iran marshes, as a biological dressing on wounds. MATERIALS AND METHODS In thi...
