In the present study, ovarian follicular fluid and serum biochemical, hormonal, electrolytes and amino acids profiles in female dromedary camel (Camelus dromedarius), were investigated. Fluid from small (2-6 mm) and large follicles (7-20 mm) and blood samples were collected from 25 clinically healthy adult female camels. The concentrations of glucose, cholesterol, triglycerides, high-density lipoproteins, urea, total proteins, albumin, globulin, fibrinogen, alanine aminotransferase, aspartate aminotransferase and tri-iodothyronine were lower (p < or = 0.05) in large follicles when compared with the small follicles. However, the concentrations of low-density lipoproteins, uric acid, creatinine, alkaline phosphatase and acid phosphatase in small and large follicles did not differ. The concentrations of oestradiol 17-beta and progesterone were higher (p < or = 0.05) in large follicles. The serum concentrations of these hormones were many folds lower (p < or = 0.05) than those of follicular fluid. Among electrolytes, the concentration of phosphorus was higher (p < or = 0.05) in the large follicles, while that of potassium and chloride were lower (p < or = 0.05) in the small follicles. Serum concentrations of sodium, chloride, calcium and phosphorous were higher (p < or = 0.05), while that of potassium lower (p < or = 0.05) than corresponding concentrations in the follicular fluid. The concentrations of leucine and arginine were higher (p < or = 0.05) in follicular fluid when compared with serum concentrations, while the reverse was true for other amino acids. In conclusion, this study is indicative of either low or high concentrations of certain biochemical metabolites, hormones, electrolytes and amino acids in small and large follicles for the individual roles that they play in the growth and development of follicles in the one-humped she-camel.

In this study, anterior pituitary glands were collected from 12 young male buffalo calves after slaughter, cultured with gonadotropin releasing hormone (GnRH) and estrogen stimulus and the extract obtained. Adult male rabbits (n = 15) were divided into three equal groups. Rabbits of Group A served as control; those of Groups B and C were given extract containing 4 and 8 mIU of follicle stimulating hormone (FSH), respectively twice daily for 3 weeks. Body weight of rabbits was recorded before and after treatment; blood samples were collected after treatment and analyzed for hemoglobin (Hb), red blood cell (RBC) count, white blood cell (WBC) count, packed cell volume (PCV), platelet counts, mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH), while serum samples were analyzed for FSH and total cholesterol. Then, all rabbits were slaughtered, and weight of paired testes was recorded. Results showed that the values for weight gain, RBC count, WBC count, PCV and MCH did not differ among rabbits of three groups. Blood Hb was greater (P < 0.05) in rabbits of Group B than Group C. Testis weight, serum FSH, total cholesterol and blood platelets count were greater in rabbits of Groups B and C, while MCV was less in rabbits of Group C, compared to the control (P < 0.05). In conclusion, in vitro cultured cells of adenohypophysis from male buffalo calves showed FSH activity. This FSH increased testes size, serum FSH, total cholesterol and blood platelets counts and decreased MCV in rabbits. However, it had no effect on weight gain, RBC counts, WBC counts, PCV and MCH.
