Objective: In the living organisms, deleterious effects produced by ionizing radiations. Human exposure to ionizing radiations increased enormously because of rapid technological advancements. There is a need to protect humans against such effects of ionizing radiation. Protection against the deleterious effects of ionizing radiations by radioprotectors was studied, which may be of great help for human application. Present study was conducted to evaluate the modulating efficacy of prolonged administration of Aloe vera extract against gamma irradiation-induced toxicity in mice. Methods: Animals were given Aloe vera leaf extract orally 1000 mg/kg body weight/d for 15 consecutive days before radiation exposure (0.5, 3 and 5.5 Gy gamma radiation). Results: Mice were autopsied at day ¼, 1, 3, 5, 10 and 20 after irradiation to evaluate the radio modulator effect in terms of the hepatosomatic index. Conclusion: Aloe vera extract has a beneficial protective effect against radiation-induced oxidative stress.

The processed Aloe vera gel (PAG) contains immunomodulatory polysaccharides, which consists of a mixture of polymer chains of b-(1,4)-linked acetylated galactomannan with different lengths. PAG was shown to inhibit azoxymethane(AOM)-initiated and dextran sodium sulfate(DSS)-promoted colon carcinogenesis model in mice. In the present study, we examined the molecular mechanisms for the inhibition of colitis-associated colon carcinogenesis by PAG. PAG administration significantly inhibited the production of pro-inflammatory cytokines and mediators in the colon. Western blot analysis using the colon extracts showed that PAG administration reduced the activation of NF-kB resulting in the inhibition of iNOS and COX-2 expression. PAG appeared to inhibit NF-kB activation through the PPARγ activation. PAG administration also inhibited the expression and phosphorylation of STAT3, which was known to connect inflammation and cancer. PAG administration also inhibited cell cycle progression-related transcription factors such as the proliferating cell nuclear antigen (PCNA), ERK, cyclin-dependent kinase (CDK) 4 and cyclin D1. In contrast, PAG administration increased the expression of CDX2, which was known to be a tumor suppressor in colorectal cancers. These findings show that PAG suppresses colitis-related colon carcinogenesis by inhibiting both chronic inflammation and cell cycle progression in the colon.

The efficacy of Aloe vera has been known for various health and disease-related conditions. Butyrate, a well-known epigenetic histone deacetylase inhibitor, is causally implicated in tumorigenesis and tumor angiogenesis. Butyrate was shown to induce cell cycle arrest, differentiation, and apoptosis in a variety of cancer cells. Dietary factors, microbiota composition, and microbiota metabolism are intimately intertwined in a complex network, highlighting the importance of intestinal functions for health maintenance. In the present review, we discuss aloe vera fermentation as a tumor-suppressive process generating microbial-derived butyrate.

Background Dermatophytosis in calves is a major public and veterinary health concern worldwide because of its zoonotic potential and associated economic losses in cattle farms. However, this condition has lacked adequate attention; thus, to develop effective control measures, we determined ringworm prevalence, risk factors, and the direct-sample nested PCR diagnostic indices compared with the conventional methods of dermatophytes identification. Moreover, the phenolic composition of an Aloe vera gel extract (AGE) and its in vitro and in vivo antidermatophytic activity were evaluated and compared with those of antifungal drugs. Results Of the 760 calves examined, 55.79% (424/760) showed ringworm lesions; 84.91% (360/424) were positive for fungal elements in direct-microscopy, and 79.72% (338/424) were positive in culture. Trichophyton verrucosum was the most frequently identified dermatophyte (90.24%). The risk of dermatophytosis was higher in 4–6-month-old vs. 1-month-old calves (60% vs. 41%), and in summer and winter compared with spring and autumn seasons (66 and 54% vs. 48%). Poor hygienic conditions, intensive breeding systems, animal raising for meat production, parasitic infestation, crossbreeding, and newly purchased animals were statistically significant risk factors for dermatophytosis. One-step PCR targeting the conserved regions of the 18S and 28S genes achieved unequivocal identification of T. verrucosum and T. mentagrophytes in hair samples. Nested-PCR exhibited an excellent performance in all tested diagnostic indices and increased the species-specific detection of dermatophytes by 20% compared with culture. Terbinafine and miconazole were the most active antifungal agents for dermatophytes. Gallic acid, caffeic acid, chlorogenic acid, cinnamic acid, aloe-Emodin, quercetin, and rutin were the major phenolic compounds of AGE, as assessed using high-performance liquid chromatography (HPLC). These compounds increased and synergized the antidermatophytic activity of AGE. The treated groups showed significantly lower clinical scores vs. the control group (P

The medicinal and other claimed uses of Aloe vera, the “wonder plant”, are endless. The extract for phytochemical analysis was collected in three different solvents, diethyl ether, ethanol and distilled water. The anti-fungal activities of the leaf extract were investigated on selected fungi organisms; Trycophytum rubrum, Penicillum notatum, Trycophytum vericophytum, Trycophytum soundanense, Claudosporium and Trycophytum mentagrophytis collected from Mycology Laboratory, University of Nigeria Teaching Hospital, Enugu, Nigeria. The plant extract was collected crude without solvent and agar-well diffusion method employed for the determination of antifungal activities on the test organisms using 200 mg ketoconazole drug as standard. The phytochemical constituents of aloe vera leaf include alkaloids, flavonoids, saponin, phenol, glycosides and tannins. Both undiluted and half diluted crude extract showed different zones of inhibition on the test organisms. The undiluted crude extract of Aloe vera had larger zone of inhibition on Trycophytum rubrum and Trycophytum mentagrophytis than the diluted crude extract while the diluted crude extract showed larger zone of inhibition on Trycophytum vericopytum than the undiluted crude extract.Keywords: Aloe vera, Phytochemicals, Constituents, Antifungal properties

Recurrent aphthous stomatitis (RAS) is the most common disorder in the oral mucosa that affects the daily quality of life of patients, and there is currently no specific treatment. In the present study, we developed aloe vera fermentation gel under the action of probiotics on aloe vera. In total, 35 patients with the history of aphthous stomatitis were enrolled to explore the potential benefits of aloe vera fermentation gel to treat RAS, and the healing-promotion effects were recorded and compared; microbial compositions in different groups were tested by high-throughput sequencing. Our results indicated that the duration of healing time of the aloe group showed potentially better effects because of the higher proportion of 4–6 day healing time (35% vs. 20%) and lower proportion of 7–10 day healing time (65% vs. 80%) compared with that of the chitosan group. Also, the use of aloe vera fermentation gel could return oral bacteria to normal levels and reduce the abundance of harmful oral bacteria including Actinomyces, Granulicatella, and Peptostreptococcus. These results suggest that aloe vera fermentation gel has the ability to treat patients with RAS and has positive prospects in clinical applications.
