Production of Mercaptoethanol Sensitive Antibody in Bursectomized Chicks

Early 2-mercaptoethanol-resistant antibody production in endotoxin-treated rats.

Experiments are reported concerning both natural and specific antibody production in endotoxin-treated rats.

Antibody and Immunoglobulin Production at the Cellular Level in Bursectomized-irradiated Chickens

The effect of bursectomy combined with sublethal X-irradiation in the newly hatched chicken on the immunoglobulin and antibody producing capacity in later life was investigated. The previous findings of a significant incidence of hypogammaglobulinemia in such animals were confirmed. Spleen cells from severely hypogammaglobulinemic animals synthesized and secreted little or no immunoglobulin. Su...

Evaluation of maternal antibody levels for establishing the vaccination program against Newcastle disease in ostrich chicks

  Newcastle disease virus (NDV) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in Iran. Therefore, establishing a routine vaccination program against ND in ostrich flocks would be useful in order to reduce the danger of this infection. Newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losse...

molecular and physiological characterizations of floral scent production in rosa damascena mill.

گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
