  Background & Aim: One of the major problems of modern medicine is the increasing consumption of synthetic drugs and frequent use of them will result in side effects. Considering this issue, patients should be mainly motivated to use pharmaceutical plants. Regarding the positive effects of sumac on the immune system, in the present study, we made a decision to compare sumac with levamisole as a chemical immune system stimulant compound. Experimental: In this research, 8 native breed of dogs were studied for ten days. The dogs were divided into four groups of two including a control group, a group consuming levamisole, a group consuming the amount of 10 mg per kg sumac, and a group receiving 5 mg per kg sumac. Then, blood samples were taken and the relevant tests were performed after completing the period of intaking the prescribed amount of powders of sumac plant and oral levamisole. Results: According to present results, significant differences were observed between treatment and control groups in terms of some factors including phagocytosis, multiplicity of phagocytosis mass and IGM whereas there was no significant difference in other factors (p < 0.05). It was revealed that sumac plant same as levamisole can increase immunity and phagocytosis in dogs. Recommended applications/ industries: In present study, considering the significant positive effects of sumac on some immunological parameters, this herb is recommended to be prescribed in the food. پرونده مقاله

  Serum protein profile could be considered as a useful indicator of physiological and pathological conditions, but several factors may interfere with the interpretation. This study was conducted to evaluate serum protein fractions in association with age, body weight, birth type and birth season in a meat-type sheep. Blood samples were randomly taken from 96 healthy Lori-Bakhtiari ewes in the Shooli breeding station in Iran. The sampled animals randomly belonged to different age, birth type, birth season and body weight groups. Total protein and other fractions were determined by Biuret and electrophoresis methods, respectively. IgG levels were measured by ELISA method. Total protein, albumin, total globulins, albumin/globulins ratio, α1, α2, β and γ globulins and IgG levels averages were 5.82, 2.35, 3.47, 0.69, 0.06, 0.42, 0.15, 2.82 and 1.56 g/dL, respectively. Total protein had high correlations with total and γ globulins, while albumin and IgG were almost independent from other fractions. Levels of serum protein fractions in adults were also independent from body weights at different ages. Serum protein profile was significantly affected by age and birth season (P<0.05), where by older ewes had lower levels of α2, γ and total globulins and higher albumin/globulin ratios. The winter-born ewes significantly had higher γ globulins levels and probably more immune system activities, compared to the spring-born ewes. Body weight and birth type did not have any significant effect on the studied serum protein fractions. This study suggested that the age and birth season should be considered for interpretation of the serum protein profiles. پرونده مقاله
