Background and Objectives: Dermatophytosis induced by Trichophyton mentagrophytes is a major human and animal fun- gal contamination. Antifungals like terbinafine and fluconazole are widely used to treat dermatophytosis; nevertheless, the prevalence of drug resistance has increased. Hence, novel curative strategies are needed. In the present study, we compared the efficacies of conventional and nanoform of antifungals agents in guinea pig model of dermatophytosis. Materials and Methods: Guinea pigs (n=36) were injected (the posterior dorsal portion) with Trichophyton mentagrophytes conidia. The guinea pigs were divided into 6 groups (positive control, negative control, fluconazole 0.5% treated group, na- no-fluconazole treated group, terbinafine 1% treated group, and nano-terbinafine treated group), then were scored both clin- ically (redness and lesion intensity) and mycologically (microscopy and culture) until day 40 of inoculation. The treatment started 5 days after the inoculation and continued until day 40 of inoculation. Results: Assessment of the mean score of clinical lesions in groups treated with nano-drug forms of fluconazole and terbin- afine on the first day of treatment showed a score of 3 (significant redness with large scaling) and for the conventional form of terbinafine and fluconazole had a score of 4 (ulcer and scar). The decrease in lesion score in nano-drug treated groups was observed between days 15 and 20 and continued until day 40. On day 40, all groups had zero scores except the positive control group. Conclusion: This study indicated that nano-drugs are more suitable for the treatment of dermatophytosis and could be con- sidered as future alternatives for the treatment of dermatophytosis.

Dental procedures produce a large amount of spatter and aerosols that create concern for the transmission of airborne diseases, such as Covid-19. This study established a methodology with the objective of evaluating new associated strategies to reduce the risk of cross-transmission in a health environment by simulating spread of potentially contaminated dispersion particles (PCDP) in the environment. This crossover study, was conducted in a school clinic environment (4 clinics containing 12 dental chairs each). As a positive control group (without barriers), 12 professionals activated at the same time the turbine of dental drill, for one minute, with a bacterial solution (Lactobacillus casei Shirota, 1.5x108 CFU/mL), which had been added in the cooling reservoir of the dental equipment. In the experimental groups, the professionals made use of; a) an individual biosafety barrier in dentistry (IBBD) which consists of a metal support covered by a disposable PVC film barrier; b) a Mobile Unit of Disinfection by Ultraviolet-C, consisting of 8 UV lamps-C of 95W, of 304μW/cm2 of irradiance each, connected for 15 minutes (UV-C) and; c) the association between the two methods (IBBD + UV-C). In each clinic, 56 Petri dishes containing MRS agar were positioned on the lamps, benches and on the floor. In addition, plates were placed prior to each test (negative control group) and plates were also placed in the corridor that connects the four clinics. In the groups without barrier and IBBD + UV-C the passive air microorganisms in Petri dishes was also evaluated at times of 30, 60, 90 and 120 minutes after the end of the dental’s drill activation. The mean (standard deviation) of CFU of L. casei Shirota for the positive control group was 3905 (1521), while in the experimental groups the mean using the IBBD was 940 (466) CFU, establishing a reduction on average, of 75% (p<0.0001). For the UV-C group, the mean was 260 (309) CFU and the association of the use of IBBD + UV-C promoted an overall average count of 152 (257) CFU, establishing a reduction on average of 93% and 96%, respectively (p<0.0001). Considering these results and the study model used, the individual biosafety barrier associated with UV-C technology showed to be efficient strategies to reduce the dispersion of bioaerosols generated in an environment with high rate of PCDP generation and may be an alternative for the improvement of biosafety in different healthy environment.

Background. Root canal treatment is a main role in decreasing infection from root canal and pulp. The main cause of periapical damage mostly are bacteries. E.faecalis is a bactery that is found as an etiology of endodontic treatment failure. Cell wall of this bacteria is containing Lipoteichoic acid (LTA). LTA can penetrate into the periradicular tissue, act as endotoxin in host and cause periradicular inflammation then lead to bone destruction. LTA stimulates immunology reaction that produce Tumor Necrosis Factor alpha (TNF-α) and Transforming growth factors beta (TGF-ß). TNF-α is a main mediator and also have an important role in inflamation response otherwise TGF-ß is working as a multifunction  regulator of cell growth and differentiation during reforming and remodelling.  Purpose. The aim of this study is to know about the expression of TNF-α and TGF-ß during the periapical tissue damage due to induction of E.faecalis. Method. This study used laboratory experimental with the post test only control group design. A total of 30 male rats were randomly divided into 3 main groups, Group A (control negative) : normal tooth. Group B (control positive) : every tooth was induced only by sterile BHI-b. Group C (treated group) : every tooth  was induced by 10 μl BHI-b E.faecalis ATCC212(106 CFU). The animals were sacrificed 21 days later and prepared for histological examination of tissue damage, then we did the immunohistochemistry  followed by calculation on the light microscope. Result. The analysis revealed that the expression of TNF-α at treated group are higher than negative control and positive control but the expression of  TGF-ß at treated group are higher than the negative control group but lower than positive control. Conclusion. From this study we know that the expression of TNF-α and TGF-ß are changing during the periapical tissue damage that induced by E.faecalis.

Abstract Coccidiosis is one of the common poultry diseases in Iraq and the world, which causes great economic losses. Therefore, this study aimed to use a new treatment represented by nanoparticles of zinc oxide and compare it with the drug (Amprolium). The Oocysts of Eimeria tenella were isolated from the feces of the briolers received at the Veterinary hospital in Diwaniyah Province and initially diagnosed by compound light microscopy,Then it was confirmed molecularly by PCR technique using the internal transcribed space ITS1 gene with a molecular weight of 409bp. The experiment was carried out on 120 birds of broilers, as the animals were divided into 6 groups with 20 birds per group. The first group(G1) was left as a negative control(uninfected), the second group(G2) was inoculated with 50,000 mature Oocysts and left as a positive control group,the third group(G3) was incubated with 50,000 Oocysts + Amprolium (anticoccidial), the fourth, fifth and sixth groups(G4,G5,G6) were also dosed with 50,000 Oocysts followed by an oral dose of nanoparticles of zinc oxide at a concentration of 20,40,60 mg/kg for each of fourth, fifth and sixth groups respectively. The current results showed that the briolers in G2 suffered from severe disease symptoms and high mortality occurred in the first week of infection, amounting to %10 compared to the anticoccidial (Amprolium group and the groups treated with nanoconcentrations 20,40,60 mg/kg respectively.G6 which was dosed with a concentration of 60 mg /kg, showed a significant decrease in the number of Oocysts excreted compared with the positive control group and the anticoccidial group, in addition to the appearance of mild symptoms and a mortality rate of %0.8,While there was a decrease in the number of Oocysts excreted during the second week in the anticoccidial group and the treated groups with the three nanoconcentrations with a decrease in the mortality rates of birds .The number of Oocysts excreted in the litter significantly decreased in the treated group with a concentration of 60 mg/kg compared to all other groups, and all birds of this group recovered during the second week of infection.

Trigona honey (TH) is well known for its therapeutic characteristics. To date, the study of Trigona honey as a prophylactic or immune booster prior to the bacterial infection of the invivo model is not well covered. This study aims to investigate anti-inflammatory and immune activities in Wistar rats infected with respiratory infection following with Trigona honey. 25 Wistar rats were assigned to possitive groups, negative control group, positive control group was fed TH (5 g / kg body weight) orally, the untreated group was infected with Staphylococcus aureus to induce respiratory infection, the treated group has been infected with S. aureus followed by treatment with TH at a dose of 1.5 ×108 CFU / mL and the preventive group ingested TH one week before S. aureus infection. Blood was obtained for biochemical analysis. Lung tissues have been collected for molecular examination. The results showed a significant decrease in serum levels of ALT, AST, urea and creatinine in the preventive and treated groups, serum IgG increased significantly (P<0.05) in the preventive and treated groups, IFN-y increased in the preventive group while decreased in the treated group, and IL-8 increased in the treated group while decreased in the preventive group. The mRNA expression of AGP is up-regulated in the positive control, preventive and treated groups. The α2-MG, TNF-α , and mRNA expressions showed lower regulation after administration of TH in preventive and treated groups. The results show the ability of TH to counteract immune and inflammatory changes in serum levels and gene expressions.

A high-fat diet can increase lipoprotein levels, total cholesterol, (Low Density Lipoprotein) LDL, and triglycerides. Starfruit has saponin and flavonoid compounds which are expected to reducing LDL cholesterol levels. The aim of the study was to determine the effect of starfruit juice on lowering the blood cholesterol LDL of Wistar rats fed with high-fat diet. Experimental study with post-test only control group design. As many as 24 male white rats from the Wistar strain were divided into 3 groups: negative control groups (K-) that were given standard feed for 28 days; positive control group (K+) who were given a high-fat diet for 28 days; the treatment group (KP) was given a high-fat diet for 28 days and on the 15th day 28th they were given a starfruit juice with a dose of 4ml / 200grBB / day. Day 29 measured LDL cholesterol. The statistic test showed a significant increase in LDL cholesterol levels (p=0.001) in the positive control group (x=12.125±2.642 mg/dL) compared to the negative control group (x=7.625±1.506 mg/dL). There was no significant different the mean cholesterol level of the treatment group (x=11±1.927) compared to the mean LDL cholesterol level of the positive control group (x=12.125±2.642). A high-fat diet significantly increases the mean LDL cholesterol level. Starfruit juice did not significantly reduce LDL cholesterol level.

The experiment was conducted on “Cobb-500” broiler chicks to study the effects of Curcumazedoaria (shoti) on growth performances and haemato-biochemical parameters. A total of twentybroilers chicks (16 days old) were randomly divided into five equal groups (n=4). Three groups ofbroilers fed shoti powder at the rate of 10%; 20%; 30% (w/w) with other ingredients for 22 days.Broilers chicks fed on maize-soybean were considered as positive control while non-protein controlwas regarded as negative control. The results showed that body weight of broilers fed 10% and 20%shoti meal grew very close to those of control (maize-soybean) group. After having completed thefeeding trial, the birds were sacrificed to collect blood sample for and biochemical analysis .Weightsof different organs and length of intestine were also measured. Results showed that decreaseddressed weight, weight of skin and liver were found in 30% shoti treated group compared to proteincontrol group. Intestinal weight was highest in 30% shoti treated group but length was similar to theprotein control group. Total erythrocytes count, hemoglobin content and PCV value were founddecreased in shoti treated group compared to protein control group but ESR value was highest in10% shoti treated group. Total cholesterol was found to be decreased in the birds fed on shoticompared to protein control and significantly higher than non-protein control group. Triglyceride valuedecreased in 10% shoti treated group compared to protein and non-protein control group. IncreasedHDL value was found in 10% shoti treated group compared to control groups and 20 % and 30 %shoti treated groups. Result of this experiment showed that body weight of birds significantly (p<0.05)increased in all shoti treated groups. Further investigations are necessary by using differentpercentages of shoti and other shoti type feed to determine the effects of this feed supplement onanimal’s physiology. Res. Agric., Livest.

Background: Bryophyllum pinnatum is an environmental weed from the Crassulaceae family that is often used to treat convulsion, hypertension, diarrhea, insect bites, asthma and other ailments.Objectives: To evaluate the anticonvulsant potential of methanol aerial extract of Bryophyllum pinnatum plant in mice and chicks.Materials and Methods: The anticonvulsant potential was studied using Maximal electroshock Test (MEST) and pentylenetetrazol (PTZ) test in one day old chicks and mice at 250, 500 and 1000 mg/kg body weight of the extract i.p respectively. Positive control drugs used were sodium valproate (200 mg/kg) and phenytoin (20 mg/kg) in PTZ and MEST respectively while distilled water (10 ml/kg) i.p was used as negative control in all experiments.Results: The intraperitoneal LD50 of the extract was found to be greater than 5000 mg/kg body weight with an indication that the extract is relatively safe. Significant (p ≤ 0.05) prolongation of the mean onset of seizures was recorded with the extract at 1000 mg/kg body weight compared with normal saline treated group in PTZ induced seizures. Bryopyllum pinnatum methanol aerial extract also significantly reduced the mean recovery time of seizures at doses 500 and 1000 mg/kg induced by MEST when compared with normal saline treated group. Conversely, a significant (p ≤ 0.05) delay in the mean onset of seizures was recorded with standard drugs, sodium valproate (200 mg/kg) and phenytoin (20 mg/kg) in PTZ and MEST respectively.Conclusion: Methanol extract of the aerial part of Bryophyllum pinnatum possesses anticonvulsant activities.
