Sarra Bettihi | Nadia Mahdeb | Abdelouahab Bouzidi
Peganum harmala L. (Zygophyllaceae) known locally as harmel is a medicinal plant. In traditional medicine, its seeds have long been used for therapeutic purposes because of their richness in β-carboline alkaloids. This study aimed to evaluate the maternal and developmental toxicity during pregnancy by daily IP administration of 7.99 mg/kg/day (1/20 DL50) of total alkaloids extract in P.harmala’ seeds. The results summarized in confirmed pregnancy rates were high 90-100%, decreased locomotor activity, paralysis, and hypothermia. Maternal body weight and weight gain changes were statistically significant in all pregnant. Precisely, the relative weight of ovaries was significantly changed in all the groups treated. The ALAT and gamma GT concentrations show a significant change in the group treated for seven days. Significant changes in the total and indirect bilirubin levels were observed in all treated groups. The hormonal analysis showed a significant decrease in FSH levels in a treated group for seven days and two weeks, Progesterone levels were increased significantly in treated groups for seven and three weeks and increased significantly in a treated group for two groups, however, the levels of Estrogen were changed significantly only in the treated group for three. The results show a significant difference in total resorbed litters and the number of fetus deaths in the group treated for three weeks. The fetus weight in the group treated for two weeks was significant. The results show a significant decrease in the number of implantations and an increase in pre-and post-implantation loss rates, and there were no developed live or dead, and no resorbed fetuses in all treated dams, there were only implantation sites in both uterine horns. The total extract of the alkaloids in the seeds of P. harmala has adverse effects on maternotoxicity, embryonic development, and abortion.

Kani Yavuz
Crop and animal production constitute a large part of the people's livelihoods in Bayburt province. In addition, the province has become one of the important animal husbandry centers of the region due to the fact that it is a transit point between the Eastern Anatolia region and the Black Sea region. But the number of small farms in Bayburt province is still very large, and the number of farms that are members of grower organizations is quite small. In addition, the migration of the young population from villages leads to an increase in the average age of the population engaged in animal husbandry and a decrease in the number of animals that can be raised depending on the labor force. In this review, the general status of cattle and small ruminants livestock in Bayburt province was given and the level of livestock in Bayburt province was revealed with current data.

In this study; The effects of using urea as top fertilizer and "Nutrisphere-N-Urea" fertilizer, which is a nitrogen stabilizer, on some yield and quality criteria of bread wheat and corn were investigated. Experiments were carried out in the fields of the Eastern Mediterranean Agricultural Research Institute according to a randomized block design with four replications. In the wheat trial; control (no fertilizer), conventional-DAP (15 kg/da)+Urea (29 kg/da), DAP (15 kg/da)+Nutrisphere-N-Urea (15 kg/da) and DAP (15 kg/da)+Nutrisphere-N-Urea (29 kg/da) subjects including were studied. In the corn trial; 25 kg DAP/da+without top fertilizer; 25 kg DAP/da+60 kg Urea/da and 25 kg DAP/da+60 kg Nutrisphere-N-Urea/da were the subject of the research. As a result of the observations and analysis of variance, the effect of the use of "Nutrisphere-N-Urea" on yield and yield criteria in wheat, despite the classical top fertilizer (Urea) application, was found to be statistically significant. While the yield per decare was 326.88 kg in the traditional application, it was found to be 388.46 kg when Nutrisphere-N-Urea (15 kg/da) was used. In the corn trial; While the effect of the use of "Nutrisphere-N-Urea" on plant height, first ear height and hectoliter weight was found to be statistically insignificant compared to the control subject, it was seen that it caused statistically significant differences on stem diameter and yield values. The highest yield (1774.31 kg/da) and crude protein (8.95%) and low starch ratio (67.73%) were obtained from the “25 kg DAP/da+60 kg Nutrisphere-N-Urea/da” application.

The present study was aimed at isolating endophytic fungi from the Algerian medicinal plant Salicornia arabica and analyzing its antifungal and antibacterial effects. The morphological analysis allowed us to identify endophyte isolates at the genus level as belonging to 8 different genera, Aureobasidium sp., Ulocladium sp., Acremonium sp., Stemphylium sp., Penicillium sp., Aspergillus sp., Phoma sp., and Chrysosporium sp. with frequency percentages 6.7%, 13.3%, 20%, 13.3%, 13.3%, 13.3%, 6.7%, 6.7%, respectively. The antimicrobial activity was caried out using the agar plug diffusion method. The three isolates of the genus Acremonium sp. were highly active against all tested bacteria except Enterococcus faecalis. Comparison of the means of inhibition zones of the active isolates showed that the three fungal isolates of Acremonium were the most active, followed by Chrysosporium sp., Penicillium sp.1, Aureobasidium sp., Stemphylium sp.1, Penicillium sp. .2, and Ulocladium sp.2. The widest zones of inhibition were 22.33 and 20.33mm for Acremonium sp.3, 18.33 and 15.33mm for Aureobasidium sp., 19.33mm for Penicillium sp.1, and 19 and 15mm for Stemphylium sp.1 obtained against Bacillus cereus and Staphylococcus aureus bacteria, respectively. Regarding the antifungal activity, the best inhibitory activity was 80 and 64.70% obtained with the isolate Penicillium sp.2 against Fusarium oxysporum f.sp. ciccri and Fusarium oxysporum f.sp. albedinis, respectively, and of 63.29 and 58% observed against Phytophthora infestans and Fusarium oxysporum f.sp. ciccri, respectively, with the endophytic isolate Aspergillus sp.2. These results indicated the possible prospect of endophytes fungi isolated from Salicornia arabica as a promising resource of antimicrobial compounds and in the quest for the potential starting points for the development of new antibiotics.

Propolis is a resinous substance produced by bees that is rich with phenolic and flavonoid compounds. Extract of propolis has a high antioxidant and antimicrobial properties due to the presence of these compounds. Therefore, the main objectives of this study were to examine the antibacterial and the antioxidant activities of standardized, commercial water extract of propolis in vivo assays, and to assess its impact on preservation of raw beef meatballs aerobically packaged and stored at 4ºC for 7 days. The results showed that the propolis extract demonstrated the highest antibacterial activity against Staphylococcus epidermidis in vivo test. Furthermore, meatballs prepared with the propolis extract had an extended shelf life about a week in comparison to the regular meatballs. Besides, the propolis extract was a very effective natural antioxidant agent for controlling the oxidative changes in meatballs. The propolis treatment provided 64.6% reduction in the malondialdehyde formation at the final day of storage. Color lightness and yellowness values of meatballs were not affected by the propolis treatment, only difference was observed in redness values. The pH of the meatballs prepared with the propolis extract almost stayed constant during storage, while the pH of the control meatball samples increased. In summary, propolis extract exhibited a strong antimicrobial and antioxidant activity in vivo assays and in a meat product. Accordingly, it should be used in meat product formulations to enhance preservation of meat products.
