Klei T.R. | Turk M.A.M. | McClure J.R. | Holmes R.A. | Dennis V.A. | Chapman M.R.
Eight of 10 pony foals reared under helminth-free conditions were inoculated PO with 50 Strongylus vulgaris infective larvae/week for 4 weeks, at which time 1 foal died of acute verminous arteritis. Inoculation of 7 remaining foals continued at 2-week intervals for 20 weeks. Of the 7 foals, 3 were treated with ivermectin (0.2 mg/kg of body weight) in an oral paste formulation at experiment weeks 8, 16, 24; 4 foals were not treated. Two foals were not inoculated or treated and served as controls. After the first ivermectin treatment, ivermectin-treated foals had fewer days (12 +/- 2.9) with rectal temperatures > 38.6 C than did nontreated foals (23.3 +/- 3.8). Mean baseline rectal temperatures were 38 +/- 0.2 C. Adverse clinical reactions to ivermectin treatment were not observed in foals. Foals were euthanatized and necropsied 3 weeks after the last ivermectin treatment (week 24). Ivermectin was effective in reducing S vulgaris arterial larval and intestinal adult parasite numbers by 100% in 3 treated foals. Strongylus vulgaris arterial larvae and/or adults were recovered from all 4 nontreated inoculated foals. One nontreated inoculated foal lacked arterial larvae or active arterial lesions, indicating that protective resistance had developed in this individual. Marked gross and histopathologic lesions typical of chronic S vulgaris infection were observed in the 3 nontreated inoculated foals with arterial larvae. Repeated killing of intra-arterial S vulgaris fourth-stage larvae in ivermectin-treated foals did not exacerbate lesions associated with verminous arteritis or induce unique lesions associated with repeated destruction of arterial larvae. Arterial lesions in treated inoculated foals were markedly reduced and had resolved, compared with those in nontreated inoculated foals.

The aim of this study was to evaluate clinical and histopathological aspects of topical application of pure and ozonized andiroba oil (Carapa guianensis Aublet.) on the healing process of wounds of healthy horses. Eight 6.25-cm2 wounds were surgically produced on each horse, cranial to the sacrum, being four wounds on each side of the lumbar region. In three animals, left side was used for macroscopic observations and area measurement and right side was used for histopathological analysis. For the other two animals, evaluations were inverted. Beginning of the topical treatment occurred 12 hours after surgical induction of the injuries and was maintained daily until complete healing of the wounds, using sequentially and bilaterally in the craniocaudal direction saline solution (GC), ozonized saline solution (GO), pure andiroba oil (GAP) and ozonized andiroba oil (GAO). Randomly, sequence of the treatments was modified. Macroscopic and histopathological analyses were performed at 3, 7, 14, and 21 days after surgery. Completed healing time for all wounds were recorded. A wound contraction of 67.75% for GC, 65.26% for GO, 67.91% for GAP, and 69.84% for GAO were recorded. Histopathologic evaluation revealed that wounds from the GAO and GAP had an advanced epithelialization, fibroblast proliferation and collagen deposition, moderate vascular proliferation, and presence of PMN infiltrate and discrete viewing of MN. It was possible to conclude that all treatments had benefits when comparing to control group and both pure and ozonized andiroba oil can be good options for wound treatment in horses.

The contribution of equines in sustaining the livelihoods of many people, particularly in developing countries is evident. However, their socioeconomic importance is often overlooked and consequently they are given poor husbandry practices which substantially threaten their welfare. The occurrence of wounds is among other health threads which stem from such poor practices. A cross-sectional study was undertaken on 420 randomly selected equine from September to December 2022 with the objective to determine the prevalence of equine wounds and identifying influencing factors associated with the prevalence. Binary logistic regression was used for determining the prevalence of wounds in different parameters. Odds ratios (OR) were used to determine the degree of association between the different risk factors and the wound. The overall prevalence of equine wound was 39.0% from which 53.5% and 23.9% of wound prevalence were detected in horses and donkeys, respectively. The prevalence of wound differed significantly between different sex groups where males (50.7%) were highly affected than females (26.6%). The agro-ecological zone was found to have a significant influence on the occurrence of wounds where equines in the mountains and the foothills (46.6%) and (44.9%) respectively had higher record than those in the lowlands (26.9%). The distribution of wounds differed significantly between different body regions and more records were obtained at the back (50.0%) and the least on the legs (11.6%). The observed wound categories differed significantly, and more records were on abrasion (40.9%) and the least on incision (9.1%). It is concluded that wounds represent serious welfare problem in equines in the study area.

Soyelu, O.T.(University of Fort Hare Faculty of Science and Agriculture Department of Animal Science) | Masika, P.J.(University of Fort Hare Agricultural and Rural Development Research Institute)
A questionnaire survey was carried out to document traditional remedies used in the treatment of cattle wounds and myiasis in Amatola Basin. Eighty-three cattle farmers from nine villages were interviewed. The majority of respondents (67.9 %) use traditional remedies for treatment of these conditions. However, 25.9 % of them use a combination of traditional remedies with conventional medicines. The survey revealed that 13 medicinal plants belonging to 11 families were used. Aloe ferox, Prunus persica and Phytolacca heptandra were, however, the most commonly used. Leaves are the most frequently used plant part, often prepared as an infusion. Other non-plant remedies used include disinfectants, antiseptics as well as diesel and petrol. Manual removal of maggots from wounds was also practise and treatment is usually continued until the wound heals.

The advantages of ventral and flank approaches for ovariohysterectomy (OHE) in terms of wound healing rate when compared to each other are still understudied. The effects of different OHE approaches on the wound healing rates of cats in Selangor, Malaysia were investigated. A total of 50 female cats were randomly included in this study. They were divided into the ventral-approach group (n=25) and the flank approach group (n=25). The wound healing rates and possible complications that could arise from the surgery in all cats were monitored daily from Day 1 until Day 7 post-surgery. Data were analysed using Independent T-test. Overall, the incision site wound healing rate in cats from the flank-approach group was found to be significantly higher (P < 0.05) than in cats from the ventral-approach group (72.55 ± 3.48 % vs. 59.91 ± 3.34 %; mean ± SEM). Complete healing of the incision site was observed in 12 % of cats from the flank-approach group as compared to 8 % of cats from the ventral-approach group. However, 8 % of cats from the ventral approach group had post-surgery complications whereas the flank-approach group had none. Results from the alternative approach may be attributed to reduced accessibility and contamination of the incision site during recovery
Mostrar más [+] Menos [-]The use of modified Masson’s trichrome staining in collagen evaluation in wound healing study
2012
Suvik, A. | Effendy A. W. M.
A number of studies have measured collagen fibers and collagen
deposition in wound healing process with advances imaging techniques. However, these are performed by complicated methods and need specific tools. In search of the easier ways in routine histopathological laboratory, collagen measurement and staining pattern of wound healing process were observed in wounded skin of Sprague Dawley’s rat by using two different stains which are standard haematoxylin and eosin (H&E) and modified Masson’s
trichrome staining (MT). The comparison between these staining in wounded tissues was made to evaluate the advantages and disadvantages of both staining in wound healing study for 21 days postwounding. Tissues which stained with MT staining was then evaluated its collagen re-organization and density by using polarized light microscope with the aid of image analyzer software. Results showed that tissues stained with standard H&E could not be used to measure and differentiate the collagen deposition which is contradictory to MT staining. Wounded tissue stained with MT staining has showed a clear view of collagen fibers deposition
and re-organisation compared to H&E staining. This finding could validate the using of modified MT staining which leads to accurate histopathological analysis and observation in wound healing study.

2012
Vellayan S. | Yap, M. T.
Corona Discharge Therapy,an evidence-based therapeutic modality, was used on a 40-year-old female Malaysian elephant. The elephant was on systemic therapy for her wounds for 5 days. All therapies were then stopped for 4 days. Corona Discharge Therapy was subsequently applied on both the hind limb joints for 3 sessions. The non-invasive
treatment was made with a multi-patented, electronic therapeutic device called VET Sonotron without the concurrent use of drugs. Corona discharge beam (CDB) of the device was used to relieve the joint pain and inflammation. The skin surface of the elephant joints was scanned with the CDB emanating from a discharge electrode to
which was applied periodic bursts of radio frequency at 0.43 mHz, pulsed at 1 kHz of sound frequency. This therapy showed remarkable anti-inflammatory effects.

Investigation of antimicrobial activity of liquid extractions from the following medicinal plants and their mixtures against S. aureus, B. subtilis, E. coli, P. aeruginosa, and P. vulgaris was realized in the conditions of the Republic of Belarus: peat moss (Sphagnum); greater plantain (Plantago major); plumepoppy (Macleaya); common comfrey (Symphytum officinale); speckled alder (Alnus incana). Research results showed that the best results for septic wounds treatment were obtained apter application of mixture of plumepoppy and greater plantain as it showed the acute antimicrobial, anti-inflammatory, and wound-healthing effect. Antimicrobial activity of the analyzed infusion formula revealed in quicker (on 3-6 days in comparison with control) wound cleansing from microorganisms, quick lowering of bacterial content up to 10E3 bodies per 1 g of tissue and in provision of wound healing without inclusion of saprogenous microflora. Anti-inflammatory effect was characterized by quick (by 2 days) cancellation of acute inflammatory response, that was revealed in lowering of neutrophilic leukocytes quantity up to 59,8 +/- 0,49 %; quicker normalization hematologic indexes and early reduction of perifocal edema; weakening of hyperthemia and hyperemia; decreasing of wound secretion without purulence; absence of leaks and leak pouch; normalization of microcirculation in wound. Wound-healthing effect was revealed in increasing of fibroblast number from 7,1 +/- 0,4 % up to 29,4 +/- 0,4 % on the 7th day and in activation proliferate and synthetically function
