Phytochemical Estimation and Therapeutic Amelioration of Aesculus hippocastanum L. Seeds Ethanolic Extract in Gastric Ulcer in Rats Possibly by Inhibiting Prostaglandin Synthesis / 中国结合医学杂志

OBJECTIVE@#To quantify phytochemicals using liquid chromatography and mass spectroscopy (LCMS) analysis and explore the therapeutic effect of Aesculus hippocastanum L. (AH) seeds ethanolic extract against gastric ulcers in rats.@*METHODS@#Preliminary phytochemical testing and LCMS analysis were performed according to standard methods. For treatment, the animals were divided into 7 groups including normal control, ulcer control, self-healing, AH seeds low and high doses, ranitidine and per se groups. Rats were orally administered with 10 mg/kg of indomethacin, excluding the normal control group (which received 1% carboxy methyl cellulose) and the per se group (received 200 mg/kg AH seeds extract). The test group rats were then given 2 doses of AH seeds extract (100 and 200 mg/kg, respectively), while the standard group was given ranitidine (50 mg/kg). On the 11th day, rats in all groups were sacrificed, and their stomach was isolated to calculate the ulcer index, and other parameters such as blood prostaglandin (PGE2), tissue superoxide dismutase (SOD), catalase (CAT), malonyldialdehyde (MDA), and glutathione (GSH). All isolated stomach tissues were analyzed for histopathological findings.@*RESULTS@#The phytochemical examination shows that the AH seeds contain alkaloids, flavonoids, saponins, phenolic components, and glycosides. LCMS analysis confirms the presence of quercetin and rutin. The AH seeds extract showed significant improvement in gastric mucosa conditions after indomethacin-induced gastric lesions (P<0.01). Further marked improvement in blood PGE2 and antioxidant enzymes, SOD, CAT, MDA and GSH, were observed compared with self-healing and untreated ulcer-induced groups (P<0.01). Histopathology results confirmed that AH seeds extract improved the mucosal layer and gastric epithelial membrane in treated groups compared to untreated ulcer-induced groups.@*CONCLUSIONS@#LCMS report confirms the presence of quercetin and rutin in AH seeds ethanolic extract. The therapeutic effect of AH seeds extract against indomethacin-induced ulcer in rat model indicated the regenerated membrane integrity, with improved cellular functions and mucus thickness. Further, improved antioxidant enzyme level would help to reduce PGE2 biosynthesis.

Gelatin-based microspheres crosslinked with glutaraldehyde and rutin oriented to cosmetics

ABSTRACT Glutaraldehyde (GTA) has been extensively used as a gelatin crosslinking agent, however, new natural ones have been suggested as more biocompatible. Polyphenols are possible candidates and the flavonols, such as rutin (RUT), also exhibit potential synergism with sunscreens and antioxidant agents used in cosmetics. In this work, gelatin microspheres (M0) were obtained and crosslinked with GTA 10 mM (MG) or RUT 10 mM (MR), dissolved in acetone:NaOH 0,01M (70:30 v/v). MG exhibited crosslinking extent of 54.4%. Gelatin, M0, MG and MR did not elicit any signs of skin damage, regarding the formation of erythema, the barrier function disruption and negative interference in the stratum corneum hydration. Oily dispersions containing M0, MG or MR, isolated or combined with benzophenone-3 or octyl methoxycinnamate, suggested that the microspheres, at a 5.0% w/w, had no additional chemical or physical photoprotective effect in vitro. Crosslinking with RUT had occurred, but in a lower degree than GTA. Microspheres had not improved sun protection parameters, although, non-treated gelatin interfered positively with the SPF for both UV filters. The in vivo studies demonstrated that these materials had very good skin compatibility.

Study of efficacy and safety of a new local cream ("healer") in the treatment of chronic anal fissure: a prospective, randomized, single-blind, comparative study / Estudo da eficácia e segurança de novo creme cicatrizante para o tratamento da fissura anal crônica: estudo prospectivo, randomizado, simples-cego e comparativo

OBJECTIVES: To determine the efficacy and safety of "healer" cream as monotherapy in the treatment of acute and chronic anal fissure. STUDY DESIGN: A prospective, randomized, single blinded, comparative trial. METHODS: Sixty patients suffering from anal fissure were included in the study. Patients were randomly divided into three groups: group A: treated with "healer" local cream application 3 times daily; group B: treated with nitroglycerine 0.25 percent local cream 3 times daily; group C: treated with a lidocaine 2 percent cream applied locally 3 times daily. All the followings were followed up and compared between groups. (1) Visual pain analogue score after defecation; (2) severity of straining and discomfort during defecation; (3) frequency of ulcer healed at 30 days; (4) any side effects or complications. RESULTS: The pain scoring after defecation was significantly reduced in the three treatment groups. The group treated with "healer" isosorbide-di-nitrate showed the greatest reduction of the visual pain analogue score median from 9 before treatment to 3 & 1 after 10 and 20 days respectively, while the median visual pain analogue score in group B treated with nitroglycerine cream was 9 reduced to 4 & 2 after 10 and 20 days respectively, and the median visual pain analogue score in lidocaine group only dropped from 9 to 6 and 4, respectively. The reduction of both pain scoring and defecation scoring with "healer" was statistically significantly greater than the other two treatments by Kruskal-Wallis test, P<0.001. The number of patients experiencing complete relief and passing stools easily after 10 days was significantly higher in "healer" group, by Pearson Chi square = 22.94, P<0.001. After 30 days, the fissures were healed in 18 (90 percent) of 20 patients in the "healer" group and in 12 (60 percent) of 20 in the nitroglycerin group, while only 6 (30 percent) of patients treated with lidocaine cream had their fissures healed by ...

OBJETIVOS: Determinar a eficácia e segurança de "creme cicatrizante" (dinitrato de isosorbida 1 por cento; lidocaína 2 por cento; rutosídios 5 por cento em base de creme anti-séptico) como monoterapia no tratamento da fissura anal aguda ou crônica. METODOLOGIA: Estudo prospectivo, randomizado, simples-cego, comparativo. Foram incluídos 60 pacientes com fissura anal. Foram divididos randomicamente em três grupos: grupo A: tratados com "creme cicatrizante", grupo B: tratados com creme de nitroglicerina 0,25 por cento e grupo C: tratados com creme de lidocaína 2 por cento aplicado. Em todos foi feita aplicação local 3 vezes ao dia. Os seguintes parâmetros foram aferidos: 1) escore analógico visual de dor após defecação, 2) severidade de esforço e desconforto para evacuar, 3) frequência da cicatrização após 30 dias, 4) presença de efeitos colaterais ou complicações. RESULTADOS: O escore de dor após a defecação foi reduzido significativamente nos três grupos. O grupo tratado com creme cicatrizante mostrou grande redução do escore médio de 9 para 3 e 1 após 10 e 20 dias de tratamento, respectivamente, enquanto que a média do grupo B foi reduzida de 9 para 4 e 2 e do grupo C de 9 para 6 e 4 após 10 e 20 dias de tratamento, respectivamente. A redução tanto da dor como do desconforto evacuatório com o uso de "creme cicatrizante" foi significativo em comparação com os outros cremes pelo teste de Kruskal-Wallis, P<0,001. O número de pacientes que referiram alívio completo e passagem fácil da fezes após 10 dias de tratamento foi maior e significativo no grupo A pelo teste Pearson, P<0,001. Após 30 dias, as fissuras estavam cicatrizadas em 18 (90 por cento) pacientes do grupo A, em 12 (60 por cento) do grupo B e em apenas 6 (30 por cento) do grupo C. Qui ao quadrado = 15 (P = 0,001). CONCLUSÃO: O "creme cicatrizante" é um tratamento que promete ser promissor e seguro na fissura anal aguda ou crônica. A característica farmacocinética do creme leva ...
