Background and Aim: Recently, many medicinal plants have received considerable attention in the medical field because of their role in the wound healing potential. This study aimed to determine the effectiveness of H. tuberosus powder on the healing pathway of full-thickness cutaneous wounds in a mouse model. Materials and Methods: H. tuberosus powder was prepared by a freeze-drying process using a lyophilizer and its active ingredients were evaluated by high-performance liquid chromatography (HPLC), while its antibacterial properties were evaluated by agar well diffusion assay. The percentage wound contraction was also assessed. Thirty mice were used, which were divided equally into two groups, a control group and a treated group. A full-thickness wound, 1 cm×1 cm in size, was established on the dorsal aspect of the thoracolumbar region, into which H. tuberosus powder was topically applied in the treated group. In contrast, the control group was left without any treatment. The animals were euthanized on days 7, 14, and 21 after wounding for histopathological study. Results: The agar well diffusion method indicated the antibacterial activity of H. tuberosus, while the HPLC results indicated that the active ingredients of H. tuberosus powder mainly consisted of three major kinds of fatty acid. In addition, the macroscopic results of wound contraction rate and the histopathological outcomes of the healing process were significantly (p≤0.05) enhanced in the treated group compared with those in the control group. Conclusion: H. tuberosus powder acts as an antibacterial agent with the ability to enhance the wound healing process.

This study designed to evaluate the effect of Erythritol injection in decreasing of abortion rate in local breed ewes. Fifty pregnant ewes from local breed aged 2–4 years with a history of abortion except G1, were fed ad libitum hay and grains with water. The study was carried out in Salah Aldein province at special farm at a period of July–November 2022. These animals were tests for brucella by using rose Bengal and ELISA at zero day for confirmation; these animals were divided into 5 groups: G1 was brucella −ve and pregnant at 60 days, G2 was brucella +ve and pregnant at 60 days, G3 brucella+ve pregnant animals and treated by antibiotics gentamicin 10%, 3 ml/animal for 3 days, G4 brucella +ve and pregnant and giving erythritol, 10 ml S/C of 10% solution (solve in water and glycerol), and G5 was brucella +ve, and all pregnant and giving Erythritol+ gentamycin 10%, 3 ml/animal for 3 days. The experiment takes 12 weeks. Blood was withdrawn at different times of experiment (0, 2 weeks and end of experiment). The seroprevalence of brucellosis was shown that all animals at G4 and G5 where seropositive after 14 days of experiment, at end of pregnancy the seropositivity were highly significantly in G4 and G5 as compared with another groups. The current results showed that percentages of abortion were higher in G2, followed by G3, while it has been reduced significantly in G4 and G1. In conclusion, Erythritol alone can decrease the rate of abortion by making the bacteria extracellular far from placenta and evading of infection by immunity and/or gentamicin injection. Also, erythritol can be used as elicit diagnosis of brucellosis in latent infected animals.

Two techniques of single-layer closure were studied experimentally by created cystotomy in six male rabbits, they separated randomly into two equal groups (A and B). In animals of either groups, cystotomy was initiated experimentally on the dorsal side of the urinary bladder wall through standard midline ventral laparotomy. In group A, the cystotomy wound was closed by single-layer, full thickness, simple continuous pattern, while in group B, the closure was accomplished by single-layer continuous Lambert pattern, applying polydioxanone PDS (3/0) in the two groups. The effectiveness of cystotomy wound healing and a urine-firm seal of the urinary bladder were examined at days 3, 7 and 14 post-operatively by gross changes. In both groups, the macroscopic observation revealed thickening of the bladder wall with adhesion in both groups, the microscopic evaluation showed optimum healing at the site of cystotomy wound sealing on the 14th day post operation despite a slight to moderate adhesions were noted in both groups. The histological evaluation of the urinary bladder biopsies indicated regular epithelization of the mucosal coat and normal arrangement of the muscularis and serosal layers at the location of cystotomy closure were evident in animals of both groups on the 14th day post operation.
