Efficacy of Mouthwash from Aloe vera Juice after Scaling Treatment on Patient with Gingivitis: A Clinical Study

Objective: To determine the effectiveness effectivity of mouthwash from Aloe vera juice after scaling treatment on patient with gingivitis. Material and Methods: This was an experimental research using pretest and posttest design with control group. The number of samples of 30 people selected using sampling method quota sampling. Samples were divided into two groups: test (n = 15 skeletons with Aloe vera juice) and control (n = 15 just scaling). Gingival inflammation is measured using a gingival index according to Loe and Sillness on the first day before scaling treatment and 7th day after scaling. Data analysis was conducted using SPSS version 20. Independent-samples t-test and paired-samples t-test were used for data analysis. The statistical test performed has a significance level of 0.05 (p = 0.05) and confidence level of 95% (α = 0,05). Results: There was a significant decrease in the mean score of the gingival index in the control group (1.1 to 0.5) and the test group (1.2 to 0.4) significantly (p<0.05). Conclusion: The use of mouthwash from Aloe vera juice can decrease gingival inflammation, which can be seen from the gingival index score on all test subjects. The decrease in gingival index in the test group using the Aloe vera juice was greater than that of the control group, which was not given the mouthwash.

Influencia del Aloe vera L sobre la respuesta inmune humoral de ratones Balb/C inmunizados contra el virus de la hepatitis B / Influence of Aloe vera L on the immune humoral response of Balb/C mice immunized against the hepatitis B virus

Se realizó un estudio utilizando el extracto acuoso de Aloe vera L para determinar su actividad inmunogénica en ratones Bal/C inmunizados con la vacuna recombinante contra hepatitis B (Herbiovac HB) de producción nacional. Específicamente se evaluó la latencia, la intensidad, la durabilidad y la memoria inmunológica a través de extracciones que se les hicieron en varios tiempos (3, 5, 27 semanas, 1 año y 15 días después de los 2 últimos tiempos); la muestra obtenida fue procesada mediante micro ELISA tipo sandwich para cuantificar anticuerpos contra el virus de la hepatitis B (anti HB). Se trabajó con 2 grupos de trabajo (control y tratamiento con Aloe) a los que se les inoculó por vía subcutánea solución salina y extracto acuoso inyectable de Aloe B M respectivamente durante 21 días. Los resultados obtenidos mostraron que todos los animales sero-convirtieron y tuvieron hiper-respuesta; además se encontró elevación de la respuesta humoral con presencia de los títulos de anticuerpos protectores después del año. Los estudios de anatomía patológica a los órganos primarios y secundarios de la respuesta inmune denotaron proliferación celular en timo y aumento del área de células B en el bazo(AU)

Chemical characterization of the immunomodulating polysaccharide of Aloe vera L.

The polysaccharide isolated by alcohol precipitation of Aloe vera mucilaginous gel was found to have a Man:Glc:Gal:GalA:Fuc:Ara:Xyl ratio of 120:9:6:3:2:2:1 with traces of Rha and GlcA. Linkage analysis of the endo-(1-->4)-beta-d-mannanase-treated sample yielded Manp-(1--> (approximately 26%), 4-Manp (approximately 53%), 2,4-Manp (approximately 3%), 3,4-Manp (approximately 1%), 4,6-Manp (approximately 1%), 4-Glcp (approximately 5%), 4-Xylp (approximately 1%), Xylp-(1--> (approximately 2%), Galp-(1--> (approximately 5%), and traces of 4,6-Galp and 3,6-Galp. Hydrolysis with strong acids produced a mixture of short oligosaccharides and an acid-resistant fraction containing greater relative fractions of Manp-(1-->, Araf-(1-->, Xylp-(1-->, and 4-Xylp than the bulk polysaccharide. NMR analysis of oligosaccharides generated by endo-(1-->4)-beta-D-mannanase and acid hydrolysis showed the presence of di-, tri-, and tetrasaccharides of 4-beta-Manp, beta-Glcp-(1-->4)-Man, beta-Glcp-(1-->4)-beta-Manp-(1-->4)-Man, and beta-Manp-(1-->4)-[alpha-Galp-(1-->6)]-Man, consistent with a backbone containing alternating -->4)-beta-Manp-(1--> and -->4)-beta-Glcp-(1--> residues in a approximately 15:1 ratio. Analysis of the sample treated sequentially with endo-(1-->4)-beta-d-mannanase and alpha-D-galactosidase showed that the majority of alpha-Galp-(1--> residues were linked to O-2, O-3, or O-6 of -->4)-beta-Manp-(1--> residues, with approximately 16 -->4)-beta-Manp-(1--> residues between side chains. Our data provide direct evidence of a previously proposed glucomannan backbone, but draw into question previously proposed side-chain structures.

Two functionally and chemically distinct immunomodulatory compounds in the gel of Aloe vera.

An aqueous extract of Aloe vera gel was analyzed guided by modulatory activity with regard to the in vitro activation of human complement and of human polymorphnuclear leucocytes (PMN). Upon ultrafiltration a high (h-Mr) and a low (l-Mr) molecular mass fraction were obtained. Pre-incubation of human pooled serum with the h-Mr fraction resulted in a depletion of classical and alternative pathway complement activity. In contrast, only the l-Mr fraction could inhibit the production of free oxygen radicals by activated PMNs. The latter activity cannot be attributed to non-specific effects like toxicity, interference with stimulant binding or scavenger activity.

[Immunomodulating properties of an extract isolated and partially purified from Aloe vahombe. 3. Study of antitumoral properties and contribution to the chemical nature and active principle]. / Etude des propriétés immunodulatrices d'un extrait isolé et partiéllement purifié à partir de l'Aloe vahombe. 3. Etude des propriétés antitumorales et contribution à l'étude de la nature chimique du principe actif.

An immuno-modulator fraction (Alva) extracted from an endemic plant, in the south of Madagascar, the Aloe vahombe, significantly protects mice against bacterial, parasitic and fungal infections. Wishing to verify whether the fraction Alva was active in tumour reduction, we studied its effect on the development of experimental fibrosarcoma and melanoma in mice by intravenous and intracutaneous injections and injections directly into the tumour of the immunostimulant fraction. We have observed cures, only in the case of the McC3-1 tumour but it is encouraging to note that under different experimental conditions the rate of growth of tumours in animals which were treated is slower than in those not treated. The Alva fraction is a substance which is hydrosoluble, thermostabile, having a molecular weight exceeding 30 000 and is a polysaccharide. The predominant sugars are glucose and mannose in 3:1 ratio. Preliminary studies of its action seem to indicate that the Alva fraction acts upon non-specific response and could possibly stimulate the phagocyte activity of the peritoneal macrophagus.

Hypersensitivity to aloe.

Hypersensitivity, manifested by generalized nummular eczematous and papular dermatitis, and presumably by contact urticaria, developed in a 47-year-old man after four years of using oral and topical aloe. Patch tests for aloe were positive in this patient.
