O trabalho objetivou verificar a influência do mel e do propólis na cicatrização de feridas limpas por segunda intenção, induzidos cirurgicamente. Foram utilizados 60 ratos, Wistar, fêmeas, com peso inicial entre 200 e 250 gramas, divididos em três grupos de vinte animais. Produziu-se uma ferida cutânea limpa na região torácica lateral esquerda e os animais foram submetidos aos seguintes tratamentos: grupo I – própolis, grupo II – mel e grupo III – solução fisiológica 0,9% (controle). Com três, sete, 14 e 21 dias pós-operatórios, as feridas foram mensuradas e cinco ratos de cada grupo submetidos à eutanásia, para proceder exame histológico. A análise estatística das áreas das feridas não revelou diferenças significativas entre efeito de cada tratamento e número de dias após o tratamento. Histologicamente, os tratamentos com mel e própolis induziram melhor cicatrização pela redução da resposta inflamatória, havendo reepitelização mais rápida com o própolis. Use of propolis or honey in the treatment of clean wounds induced in rats Abstract Sixty female Wistar rats, initial weight from 200 to 250 g, were divided in three groups of twenty animals each. A clean skin wound was produced at the left lateral thoracic region. The wounds were treated with propolis (G1), honey (G2) and 0.9% saline solution (G3 – control). Wounds were measured and five rats were euthanatized at 3, 7, 14 and 21 days postoperative to perform the histopathologic examination. There were no statistical differences among the effect of each treatment and number of days after the treatment. The histological examination showed that honey and propolis treatments induced better healing compared to saline solution due to the reduction of the inflammatory response, but the reepitelization was faster using propolis.

HGF is one of the factors taking part in regeneration and recovery of liver after injury. The article is dedicated to the study of influence of single HGF intake on the indices of non-specific immune response in rats after 70% liver resection in the early postoperative period. Research was conducted on 42 six-months white male Wistar rats of 250–300 g. It was revealed that level of segmentonuclear neutrophils and lymphocytes in the group with HGF intake stand at normal level on the 2nd day and normalizes to the 11th day that testifies to the decrease of inflammatory response. Increased level of leukocytes and monocytes is registered in the group with HGF intake. Also integrity of non-specific resistance in the early postoperative period on the 2nd day is registered. Suppression of phagocytosis indices with preservation of functional activity of phagocytes was registered to the 11th day.

The inflammatory response is one of natural process in the body to protect itself following tissue injury, but it can cause discomfort. Noni (Morinda citrifolia L.) leaf known as a traditional medicament to help reduce the inflammatory effect. The leaves empirically applied as a wrapping on fever or wound. The purpose of this study was to identify the anti-inflammatory effect of topical noni leaf extract paste in 5% and 10% concentration by examination of Wistar rat paw edema induced by λ-carrageenan. Twenty-four Wistar rats divided into four groups, which were negative control, positive control with diclofenac sodium 1% gel, 5% noni leaf, and 10% noni leaf paste groups. Paw edema was induced by intraplantar injection of 1% λ-carrageenan to every rat. Every treatment subsequently applied in the plantar area before injection, and the changed paw volume measured with plethysmometer at minutes 0, 30, 60, and 90. This study was at the Animal Laboratory, Faculty of Medicine, Universitas Jenderal Achmad Yani, Cimahi city in October–December 2017. The result displayed that the minimum volume after 90 minutes was on 5% and 10% noni leaf paste group, which is 1.00 mL. Kruskal-Wallis test result of inflammatory percentage was significantly different among every group in each examination time (p<0.05). Post-hoc test showed that inflammatory reduction on paw edema with noni leaf paste application on both concentrations were significantly different compared to the negative control. However, it was not different from the positive control group. This study showed that application of noni leaf paste in 5% and 10% concentration could help reduce inflammatory response on skin possibly by the active anti-inflammatory ingredients of noni leaf. EFEK PASTA EKSTRAK DAUN MENGKUDU (MORINDA CITRIFOLIA L.) TOPIKAL TERHADAP EDEMA KAKI TIKUS GALUR WISTAR YANG DIINDUKSI KARAGENANInflamasi adalah proses alami tubuh untuk melindunginya setelah cedera, namun hal tersebut dapat menyebabkan ketidaknyamanan. Daun mengkudu (Morinda citrifolia L.) dikenal sebagai obat tradisional untuk menurunkan efek inflamasi yang secara empiris digunakan untuk mengobati demam dan luka. Tujuan penelitian ini adalah mengetahui efek anti-inflamasi pasta ekstrak daun mengkudu melalui pemeriksaan edema kaki tikus yang diinduksi karagenan-λ. Dua puluh empat tikus galur Wistar dibagi menjadi 4 kelompok, yaitu kontrol negatif dengan akuades, kontrol positif (aplikasi gel Na diklofenak 1%), serta perlakuan pasta daun mengkudu 5% dan 10%. Edema dibuat dengan menginjeksi intraplantar tikus dengan 1% karagenan-λ pada tiap kelompok. Tiap-tiap perlakuan diaplikasikan sebelum tikus diinjeksi dan perubahan volume kaki tikus diukur dengan pletismometer di menit ke-0, 30, 60, dan 90. Penelitian ini dilakukan di Laboratorium Hewan, Fakultas Kedokteran, Universitas Jenderal Achmad Yani, Kota Cimahi pada Oktober–Desember 2017. Hasil pengukuran memperlihatkan penurunan volume edema kaki terkecil setelah 90 menit pada kelompok pasta daun mengkudu 10%, yaitu 1,00 mL. Hasil Uji Kruskal-Wallis terhadap persentase inflamasi berbeda nyata pada tiap kelompok dan tiap waktu pengamatan (p<0,05). Hasil uji beda menunjukkan bahwa penurunan inflamasi kaki tikus pada perlakuan pasta daun mengkudu kedua konsentrasi berbeda nyata dibanding dengan kontrol negatif, tetapi tidak berbeda dengan kontrol positif. Penelitian ini menunjukkan bahwa pasta daun mengkudu 5% dan 10% dapat membantu menurunkan reaksi inflamasi kulit dan efeknya sejalan dengan Na diklofenak karena zat aktif yang bersifat anti-inflamasi dalam daun mengkudu.

AbstractBackground:We investigated the protective effects of amla (Emblica officinalis) on the pathogenesis of oxidative stress (OS) and inflammatory response in hypothyroid rats fed with a high-fat diet (HFD) as an experimental model of hypothyroidism (HT) with obesity.Methods:A total of 80 female wistar rats (5-months-old) were divided into eight different groups. Propylthiouracil (PTU) and HFD were used to induce the experimental HT and obesity, respectively. The euthyroid and hypothyroid rats were fed either normal chow or HFD with and without amla extract (AE, 100 mg/kg bw/day) for 6 weeks. The blood and tissues, liver and kidney OS and inflammatory parameters were studied using appropriate biochemical and molecular techniques.Results:PTU and HFD per se caused OS and inflammatory response as evidenced by increased plasma MDA, TNF-α, CRP and GPx in association with decreased levels of TAS and reduced glutathione (GSH). The proteomic analysis revealed that the expressions of pERK, pP38, TNF-α, IL6, COX2 and NOX-4 were up-regulated in the liver and kidney of these rats. In addition, all these metabolic derangements were further augmented when HT was followed by the addition of HFD. This suggested that there was a synergism between HT and the intake of HFD on the development of OS and inflammatory response.Conclusions:The treatment with amla fruit extract significantly restored the redox imbalance and inflammatory signaling and ameliorated OS and inflammatory response, suggesting the use of this natural compound as an alternative remedy or adjuvant for the management of metabolic complications concomitant with HT.

The increasing number of tobacco users will directly impact to an increase in the number of passive smokers. Various harmful substances that enter the respiratory tract can cause health problems. The airway will recognize these substances as pathogen and activate immune response accordingly. Inflammatory response becomes one of the effects of body compensation due to an increased pathogen. This effect is indicated by the elevation of C-Reactive Protein as one systemic inflammatory response parameters in the body. This study aimed to determine the efficacy of red mulberry juice to reduce levels of C-Reactive Protein in Wistar rats because exposure to cigarette smoke. This is an experimental study with a post-test control group design. Animals were divided into negative control group, positive control group, and 3 treatment groups with different red mulberry doses. The positive control group showed the highest increase   in C-Reactive Protein levels compared with the red mulberry intake group (p<0,001). In conclusion, the administration of red mulberry juice can reduce inflammatory response in rats because of exposure to cigarette smoke.
