Hiba Hikmat Maqdasi* and M Al Waiz

Abstract: This is an open therapeutic trial conducted at the outpatient Department of Dermatology and Venereology, Baghdad Teaching Hospital, Medicine City in the period between January 2002 and March 2003. The aim of the present work is to evaluate the efficacy and safety of oral zinc sulphate in treatment of diffuse alopecia of unknown origin. The study included thirty female patients who treated by zinc sulpate and followed up for two months. Results revealed that the means±SD of pull-test for all patients after one month of treatment (2.8±1.3 hairs) and two months (2.8± 2.01) were decreased significantly (P = 0.0026 and 0.024 respectively) as compared with the mean (3.7± 2.5 hairs) before therapy. The correlation coefficients between serum zinc concentration and both pre-treatment and post-treatment were not significant. Patient’s self-assessment showed that most of them considered that there is no changes in their hair appearance and they were unconvinced with the results. In conclusion: Although, the results of the present study showed a significant effect of using oral zinc sulphate in treatment, but these results did not convinced patients about its validity in treatment. In such case, conduct further studies is very necessary to get more reliable results. Keywords:Chronic diffuse alopecia, zinc sulphate.

Comparative Study on the Effect of Chloroxylenol and Sodium Chloride on Brucella and Acinetobacter Growth

Abstract: A study was carried out to investigate the effect of chloroxylenol and sodium chloride on the growth of Brucella spp . and Acinetobacter baumannii isolates. Results revealed that chloroxylenol was more effect on growth of Acinetobacter sp. As compared with Brucella spp. The inhibition of the Acinetobacter growth was detected at all concentrations (3, 30 ,300 , 3000, 30000, and 40000)Mg/ ml. Although, Brucella isolates resist at 3 and 30 Mg/ ml of chloroxylenol, high growth inhibition was seen at 300 Mg/ ml of chloroxylenol. On the other hand, no difference was found in the effect of chloroxylenol on Brucella abortus and Brucella melitensis. The results confirmed that the Brucella spp. seems to be more susceptible to negative effect of high concentration of NaCl than A.baumannii. Keywords: Acinetobacter , Brucella ,Sodium chloride , Chloroxelenol.

Genetic evaluation of longevity in dairy cattle

98-104Full Text

Firas Rashad Al-Samarai* and Falah Hamed Al-Zaydi

Abstract: Longevity is a highly desirable trait that considerably affects overall profitability. With increased longevity, the mean production of the herd increases because a greater proportion of the culling decisions are based on production. Longevity did not receive adequate attention in breeding programs because genetic evaluation for this trait is generally difficult as some animals are still alive at the time of genetic evaluation. Therefore, three basic strategies were suggested to evaluate longevity for cows: Firstly, cow survival to a specific age, which can be analyzed as a binary trait by either linear or threshold models. Secondly, estimating life expectancy of live cows and including these records in a linear model analysis. Thirdly, survival analysis: a method of combining the information of dead (uncensored) and alive (censored) cows in same analysis. This review represents an attempt to shed a light on different strategies of genetic evaluation of longevity in dairy cattle in most of developed countries. Keywords: longevity, genetic evaluation, survival analysis.

Abstract: The current study was conducted in the college of agriculture – University of Anbar – Iraq, for the period from 1-3-2011 to 5-4-2011, (810) eggs were used from two broiler breeders: Arbor acres and Ross (308) of 42 weeks of age. The study aimed to know the effect of genotype of broiler breeders and storage periods (1, 5, 9 days), in addition to explore the effect of the feed additives of ginger and/or celery seeds (by 0.25 and/or 0.50 each) in broiler breeders diets on certain embryonic biomarkers: number of somites pairs at the age of 3 days (SB) and the weight of the embryo at the age of 7 and 14 days (Ewt7 ; Ewt14) weight of the hatched chicks (Htw), the percent of hatching (Hat) and certain biochemical traits of hatched chicks (PCV, WBC, Glucose, Protein and Cholesterol). Results showed significant differences between the two genotypes in hatched chicks’ indicators might be the reason in varying the performance of the resultant broiler birds, the study also showed better results in storage treatments of 1 to 5 days than 9 days in most studied characteristics. In addition, it has been observed important improvement in the characteristics of embryos and hatched chicks in feed additive treatments of ginger and celery seeds comparison with control. We can pretend that this study contribute to get chicks with good and health specification, and of high production value. Keywords: Broiler breeders, genotype, storage periods, feed additives, ginger, celery seeds.

Kinetic Study of the Effect of Gold and Silver Nanoparticles on Salivary LDH Activity

Eaman A. S. AL-Rubaee

Abstract: Noble metals nanoparticles have been prepared by a facile and clean synthesis method by laser ablation in water. The structural and optical properties of the Ag and Au nanoparticles (NPs) have been investigated. The produced nanoparticles have an average particle size of about 30 nm. The effect of gold and silver NPs was studied on the activity of lactate dehydrogenase (LDH) in saliva of healthy subjects. The results correlated with the observation that gold and silver nanoparticles have different effect on salivary LDH activity, and this effect increased with increasing the concentration of the nanoparticles. While gold nanoparticles demonstrated activator effect on salivary LDH activity, silver nanoparticles have inhibition effect on it. Keywords: Au and Ag nanoparticles, LDH activity, Saliva, Kinetic study.
