Abstract

Tea mistlestoe extract (Scurrula oortiana) has cytotoxic activity which is potential to be used in preventing viral induced-chicken tumor. The following study was designed to evaluate the effects of different inoculation routes, dosage levels, and strains of embryonated chicken eggs as media for testing the tea mistlestoe extract (Scurrula oortiana) antiviral activity. Proper inoculation route was examined by inoculation of the extract at dose level of 0,2 mg/egg into embryonated layer eggs via allantoic cavity, chorio-allantoic membrane, and yolk sac. Effect of dose level of tea mistlestoe extract on embryo development was examined in groups of embryonated broiler eggs inoculated with the extract at 0.02, 0.2, 2, 20, or 200 mg/egg. Inoculation of tea mistlestoe extract into allantoic cavity was the safest procedure as indicated by the absence of embryos mortality, and faster embryo growth compared to those of chorio-allantoic membrane and yolk sac-inoculated eggs. The extract induced different growth effects when inoculated into embryonated layer or broiler eggs. Administration of the extract at dose levels between 0,02–200 mg/egg reduced significantly the weight of broiler embryoes, but not the relative weights of liver, heart and spleen. Administration of similar dosage in layer embryoes did not cause any significant difference in the embryoes weight. This study suggests that the study of antiviral activity of tea mistlestoe extract in embryonated chicken eggs should be carried out on embryonated eggs of layer breeds and the extract should be inoculated via allantoic cavity.

Abstract

Tea mistletoe is one of medicinal herb which believed has an anticancer activity, it’s due to the capability of immunostimulator. The following research was carried out to determine the immunomodulatory effect of tea mistletoe (Scurrula oortiana) extract on chicken embryos. Twenty White Leghorn Specific Pathogen Free (SPF) 10 days old embryonated chicken eggs were divided into four groups of 5 eggs. The first group served as control and they were inoculated with aquabidestilate sterile. The second, third and fourth group was inoculated with 0.1 mg, 0.2 mg, and 0.4 mg S. oortiana extract/egg respectively. S. oortiana extract was inoculated via allantoic cavity. All experimental eggs were incubated at 37oC until day 21 and incubation was terminated before the embryos hatched. The embryos and the lymphoid organs (bursa of Fabricius, thymus and spleen) were weighed. Immunomodulatory effect of tea mistletoe extract was measured by counting the percentage of bursa of Fabricius active lymphoid follicle and the area of thymus medulla. The results showed tea mislestoe extract at the dose of 0.1mg, 0.2 mg and 0.4 mg have immunomodulatory effect on chicken embryos indicated by the increase of percentage of active lymphoid follicle of bursa Fabricius i.e. 68.8, 71.8 and 57.8% and increase area of thymus medulla i.e. 24.9 – 39.3% respectively compared to control group i.e. 22.6% of active lymphoid follicle of bursa Fabricius and 17.6% of thymus medulla area. It is concluded that S. oortiana extract at the dose of 0.1mg, 0.2 mg and 0.4 mg have immunomodulatory effect on chicken embryos.

Abstract

Nematode Ascaridia galli is an important parasitic disease in poultry and is responsible for considerable economic losses in retarded growth and lowered egg production. The effects of A. galli infection based on histopathologic description, size of small intestines villi surface and body weight change in starters was investigated. One hundred and thirty five day old chicks (DOC) were divided into three groups for three levels of infection dose rate (0,800 and 8000 infective eggs) with 3 replications of 45 DOC each. Infections were carried out every week respectively from week 2th until week 5th. Results showed that the infection of A. galli caused degeneration and necroses in villi ephitelial cells and crypts of small intestine and infiltration of leucocytes. In the heavy infection group some epithelial cells were replaced by fibrocytes. A.  galli infection decreased daily body weight gain of starter lower (5.5% in light and 13.4% in heavy dosage infection) compared to that of the non infected group. After six weeks of heavy infection the size of small intestine villi surface was decreasing to 20.0%, while the daily body weight gain was decreasing to 12.3% compared to that of the non infection group.
