Effects of the basic fibroblast growth factor and its anti-factor in the healing and collagen maturation of infected skin wound

PURPOSE: The infection is one of the main factors that affect the physiological evolution of the surgical wounds. The aim of this work is to evaluate the effects of fibroblast growth factor (FGFâ) and anti-FGFâ in the healing, synthesis and maturation of collagen when topically used on infected skin wounds of rats. METHODS: An experimental study was perfomed in 60 male Wistar rats. All animals were divided in two groups (A and B). Each group was divided in three subgroups A1, B1; A2, B2 and A3, B3. After anesthesia with pentobarbital, two open squared wounds (1cm2), 4cm distant to each other, were done in the dorsal skin of all the rats. In group A (n=30) the wounds were contaminated with multibacterial standard solution, and in group B(n=30) the wounds were maintained sterile. These wounds were named F1 (for inflammation analysis) and F2 (for collagen study). The open wounds of A1 and B1 rats were topically treated with saline solution, A2 and B2 were treated with FGFâ and subgroups A3 and B3 were treated with FGFâ and anti-FGFâ. The rats were observed until complete epitelization of F2 wounds for determination of healing time and the expression of types I and III collagen, using Picro Sirius Red staining. Inflammatory reaction in F1 wounds was studied using hematoxilineosin staining. The three variable was measured by the Image Pro-Plus Média Cybernetics software. The statistical analysis was performed by ANOVA and Tukey test, considering p<0.05 as significant. RESULTS: It was observed that infection retarded significantly (p<0.05) the time of wound scarring and the topical application of FCFb reverted the inhibition of healing caused by bacteria. The inflammatory reaction was greater in the subgroup B2 than in B1 and A3, and the difference was significant (p<0.05). It was observed greater expression of type I collagen in all the subgroups treated with FCFb, when compared with the untreated subgroups. Type III collagen was significantly decreased in wounds of B3 rats, comparing to the other subgroups. CONCLUSIONS: The FCFb accelerated the healing of open infected wounds and contributed with maturation of collagen, enhancing the type I collagen density. The anti-FCFb antibody was able to attenuate the production of both type I and III collagen

Comparative study between the effects of hyaluronic acid and acid galactan purified from eggs of the mollusk Pomacea sp in wound healing

To compare the effect of hyaluronic acid (HA) and of AG on the healing of intestine wounds. Methods: The semi-purified extract of the eggs of the mollusc was obtained by fractionation with ammonium sulfate and purification for ion-exchange chromatography. The obtained galactans were eluted in water (neutral galactan) and in 0.1 and 0.2M NaCl (acidic galactans). The in vivo study was performed with 45 “Wistar” rats, separated in three groups (n=15). Solutions containing HA 1%, GA 1% or saline solution 0,9%, was placed topically on the sutures of wounds in the small intestine of the rats. After 05, 10 and 21 days the animals were sacrificed and biopsy of the healing tissue was done. Results: The hystologic grading was more significant for HA and AG groups when compared to the group C. AG stimulated the appearance of macrophages, giant cells and increase in the concentration of collagen in the area of the wound when compared to HA. Conclusion: The topical use of GA in intestinal wounds promoted the anticipation of events that are important in the wound healing

Avaliação da assistência à saúde dos portadores de úlceras venosas atendidos no programa saúde da família do município de Natal/RN

Descriptive research aimed at evaluating the assistance offered to patients with venous ulcers, on lower limbs, attended by the Family Health Program (FHP) team, from the municipality of Natal/RN. The target population was composed of 74 patients with venous ulcers (VU), attended by the FHP teams in the 31 FHUs. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (protocol n.55/05). The data collection was performed in patients homes and in the FHUs, through structured interviews and physical examinations of patients with VU and non-participant observation during the changing of wound dressings in these Units and in users homes. The data was organized into an Excel electronic table and transported into the SPSS 14.0 program, for descriptive analysis on 2x2 contingency tables and inferential (Qui-Square χ2, Spearman Correlation, Binomial Proportion Test and p-value <0.05). The prevalence of VU (0.36/1000) in the target population (over 20 years of age) was greater than in the population registered in FHP (0.25/1000). We detected a greater prevalence in the age area of over 60 years (2.22/1000), with 2.98/1000 for females and 1.3/1000 for males (p-value=0.008). The sociodemographical and health characteristics of patients with VU revealed predominance of females (74.5%), elders over 60 years of age (67.6%), with fundamental education (74.3%), family earnings of up to 2 minimum wages (68.9%), retired (90.5%), ortostatic position (23.0%), inadequate sleep (59,9%), presence of CVI (100.0%), hypertension (44.6%) and diabetes (25.7%). As for the time of existence of the VU, 64.9% had over 1 year, and 35.1% less than 1 year), with predominance of one wound (67.6%). The changing of wound dressings is performed mostly at home, in and inadequate way, especially with incorrect cleaning techniques, likewise incorrect use of products and substances, and reduced participation of the FHP team on the evaluation and application of the dressing and choosing of products and substances. The compressive therapy is not part of therapeutic conducts for treatment in the FHUs. As for the evaluation of assistance to patients with VU, 90.5% were inadequate and only 9.5% adequate. The main inadequacy factors were the absence of: diagnosis (47.3%), consultation with and angiologist (63.5%), compressive treatment (100.0%), adequate optical therapy (98.62%), adequate dressing kit (70.3%), training for the changing of dressings (67.6%), following by the FHP team (51.4%) and performed exams (55.4%). We ve concluded that patients with VU mostly present now socioeconomical level and associated chronic diseases. Considering that assistance offered by FHP is non-systematic, fragmented, with no diagnosis planning, continual evaluation and evolution, we qualify the assistance as inadequate and with low level of solution, directly interfering on the maintenance of the VUs chronic state

Efeitos do tratamento com Hidrogel na cicatrização de úlceras venosas de membros inferiores: revisão sistemática

Chronic venous disease (CVD) is evident among the chronic diseases and affects the elderly population and primarily is responsible for leg ulcers in this population. The use of dressings in the care of a venous ulcer is a fundamental part of the treatment for healing, however, evidence to assist in choosing the best dressing is scarce. The main objective of this study was to evaluate the effectiveness of treatment with hydrogel in the healing of venous ulcers using search methods, synthesis of information and statistical research through a systematic review and meta-analysis. Randomized controlled trials were selected in the following databases: CENTRAL; DARE; NHS EED; MEDLINE; EMBASE; CINAHL. Beyond these databases three websites were consulted to identify ongoing studies: ClinicalTrials.gov, OMS ICTRP e ISRCTN. The primary outcomes were analyzed: complete wound healing, incidence of wound infection and the secondary were: changes in ulcer size, time to ulcer healing, recurrence of ulcer, quality of life of participants, pain and costs of treatment. Four studies are currently included in the review with a total of 250 participants. The use of hydrogel appears to be superior to conventional dressing, gauze soaked in saline, for the healing of venous leg ulcers; 16/30 patients showed complete healing of ulcers (RR 5,33, 95%CI [1,73,16,42]). The alginate gel was shown to be more effective when compared to the hydrogel dressing in reduction of the wound area; 61,2% (± 26,2%) with alginate e 19,4% (± 24,3%) with hydrogel at the end of four weeks of treatment. Manuka honey has shown to be similar to the hydrogel dressings in percentage of area reduction. This review demonstrated that there is no evidence available about the effectiveness of the hydrogel compared to other types of dressings on the healing of venous leg ulcers of the lower limbs, thus demonstrating the need of future studies to assist health professionals in choosing the correct dressing.
