Phoma Herbarum

In this study, spontaneous swim bladder mycosis was documented in a farmed fingerling rainbow trout from a raceway culture system. At necropsy, the gross lesions included a thickened swim bladder wall, and the posterior portion of the swim bladder was enlarged due to massive hyperplasia of muscle. A microscopic wet mount examination of the swim bladder contents revealed abundant septate hyphae, and histopathological examination showed periodic acid-Schiff-positive mycelia in the lumen and wall of the swim bladder. Histopathological examination of the thickened posterior swim bladder revealed muscle hyperplasia with expansion by inflammatory cells. The causative agent was identified as Phoma herbarum through morphological analysis and DNA sequencing. The disease was reproduced in rainbow trout fingerlings using intraperitoneal injection of a spore suspension. Necropsy in dead and moribund fish revealed extensive congestion and haemorrhages in the serosa of visceral organs and in liver and abdominal serosanguinous fluid. Histopathological examination showed severe hepatic congestion, sinusoidal dilatation, Kupffer cell reactivity, leukostasis and degenerative changes. Fungi were disseminated to the liver, pyloric caeca, kidney, spleen and heart. Although infections caused by Phoma spp. have been repeatedly reported in fish, species identification has been hampered by extensive taxonomic changes. The results of this study confirmed the pathogenicity of P. herbarum in salmonids by using a reliably identified strain during experimental fish infection and provides new knowledge regarding the course of infection.

The article is devoted to the creation of a carbohydrate product with rosehip extract in the form of sweets (glucose Fudge) with a therapeutic and preventive effect aimed at restoring the body of people exposed to intense physical and mental stress and the effects of damaging environmental factors. As carbohydrates in the recipe, simple carbohydrates (glucose) and complex carbohydrates in the form of starch molasses containing (maltose, tri - Tetra - sugars, dextrins) are used. Glucose in the formulation is the main energy ingredient, sweetener and structure-forming component that gives the product a solid consistency due to crystallization. The medicinal effect of the product is provided by rosehip extract. Numerous published studies have established its vitamin, immunostimulating and antioxidant activity, inhibition of uric acid formation and obesity, which are associated with flavonoids, other phenolic compounds, and vitamins. The list of medicinal properties of rosehip extract shows the feasibility of using it in additional nutrition of people in order to prevent diseases. For the formulation of our sweets, the extraction of crushed rosehip fruits was carried out three times with hot water at a temperature of 65-700C, followed by concentration of the extract under vacuum to 25-30% SV. The resulting extract-concentrate was introduced into the formulation in a dosage of 5.5% SV per 100 g of SV glucose Fudge, which provided the necessary dosage for the product when used from 3 (for children) to 10 sweets a day (for adults) for the prevention of colds.

Ulcerative colitis is a chronic inflammatory disease mainly affects sigmoid colon and rectum. The inflammation process will activate NF-κB and leads to proinflamatory cytokine release such as Interleukin-6 (IL-6). Fig leaves contain a high level of flavonoid which can prevent NF-κB activation, and further inhibits IL-6 secretion. This research aims to see the preventive effect of methanolic extract of fig leaves towards colon histopathological feature and IL-6 serum level on ulcerative colitis induced mice. Balb/C male mice were randomly assigned into 5 groups (n=5). The treatment groups were dextran suphate sodium (DSS) control group (group I), methanolic extract of Fig leaves dose 28 mg/ day control group (group II), and methanolic extract of Fig leaves dose 7 mg/ day (group III), 14 mg/ day (group IV), and 28 mg/ day (group V) for 14 days, which at the 8th till 14th day were given DSS to induce colitis. The results showed that both of colon mucosal damage and IL-6 serum level of group I were significantly different from other groups (p=0,029). In  conclusion, the methanolic extract of Fig leaves can improve colon mucous damage and decrease IL-6 serum level on ulcerative colitis-induced mice. Keywords: ulcerative colitis, fig leaves, colon mucousal damage, interleukin-6
