Fluctuation of some blood parameters throughout the estrous cycle in goats

Seven healthy mature Baladi does [10-14 months old] were used in the present study. Estrus was synchronized using lutalyse. Heat was detected by the use of rutting aproned buck. Individual blood samples were collected daily in the morning throughout the two successive cycles following the 1st post-synchronized cycle. Each sample was divided into three portions for determination of ERS, hematological studies as well as for serum separation for biochemical analysis. The results revealed that RBCs count and Hb concentration as well as total leucocytic count and neutrophils% were significantly higher during estrous phase, whereas, ESR and platelets count as well as lymphocyte% were significantly lower during that phase. Urea, creatinine and ACP levels were significantly low during estrous phase, whereas, ALP, AST, total bilirubin uric acid, total proteins, albumins, globulins, total calcium, inorganic phosphorus, total glucose levels were significantly higher during that phase

Some alterations concomitant with prolonged administration of estrogen

The study was done for deeper underst and ing of adverse effects concomitant with repeated administration of estrogens. It was found that, prolonged treatment, particularly with high doses, leads to deleterious effects represented by immunosuppresion, alteration of cellular structure of different organs as well as deviation of hepatorenal performance. Cautious use of estrogenic agents to avoid their drastic effect is recommended

Effects of oestradial administration on hepatorenal functions in male rats

Twenty-five mature male albino rats were used in the present study to clarify the effects of estradiol on hepatorenal function. They were divided into two groups [control group and treated group]. The results showed that there was an increase in serum level of alkaline phosphatase, ALT, AST, bilirubin, urea, creatinine, triglycerides and cholesterol following estradiol treatment. So, it was concluded that, administration of estradiol at high dose rates to mature male rats has a serious harmful effect on hepatorenal function

Effect of muscular exercise on some serum biochemical constituents in camels

Six mature healthy trained male one-humped camels of Bahttcharry breed aged from 8 to 10 years were exposed to muscular exercise, in form of running for 30 minutes. Blood samples were collected separately from each animal before and after running and sera were separated. Serum level of urea, creatinine, total proteins, albumins, cholesterol, triglycerides, total and direct bilirubin, AST, ALT as well as AP activities were determined. The results of the present investigation revealed that muscular exercise in camel induced significant increase in serum levels of urea, creatinine, total proteins, albumins triglycerides, total and direct bilirubin, AST, as well as AP activities

Fluctuations of serum gonadotropins and their specific protein binding capacities during stages of follicular development in she-camel

Both serum FSH and LH levels as well as their specific protein binding activity were determined during different phases of follicular development in she camels using the ELISA technique. Gonadotropins and their specific binding capacities in the serum showed certain fluctuation which match with the requirements of the functional activity of the ovaries. It was concluded that ovarian activity in she camel depends not only on the level of serum gonadotropins but also on the variations of their specific binding potencies

Estradiol and progesterone levels in follicular fluid and serum of non pregnant one-humped she-camel in relation to follicular development

One hundred and thirty non pregnant one humped she-camel slaughtered in Cairo abbatoir were subjected for this present work. Blood samples were collected immediately after slaughtering. The sera were collected in clean dry vials. After evaceration the ovaries were collected from the corresponding animals. The diameter of the growing mature follicles was measured. According to the size of the follicles, the animals were classified into three groups: Small [2-5 mm], medium [5-10 mm] and large sized follicles, [more than 10 mm]. The follicular fluid was aspirated from the follicles. In animals having small or medium follicles, the follicular fluid was pooled and considered as one sample. Finally ten pooled samples were obtained. Whereas animals with large size follicles, the follicular fluid was quite enough to fulfil all the required determinations. The collected sera samples of small and medium sized follicles were pooled to have ten corresponding pooled for each. The estradiol and progesterone concentration were determined in both serum and follicular fluid. The results revealed the following findings and conclusions: 1] serum estradial concentration showed a significant increase to reach its highest level in animals with large follicles. It was clearly obvious that, the hormone concentration in the follicular fluid is several times higher than in serum. 2] Serum progesterone concentrations of different groups were nearly similar to each other. Progesterone levels in the follicular fluid did not differ significantly. However, follicular progesterone concentration was also several times higher than that of serum
