RESUMO

TPDM6315 is an antipyretic Thai herbal recipe that contains several herbs with anti-inflammatory and anti-obesity activities. This study aimed to investigate the anti-inflammatory effects of TPDM6315 extracts in lipopolysaccharide (LPS)-induced RAW264.7 macrophages and TNF-α-induced 3T3-L1 adipocytes, and the effects of TPDM6315 extracts on lipid accumulation in 3T3-L1 adipocytes. The results showed that the TPDM6315 extracts reduced the nitric oxide production and downregulated the iNOS, IL-6, PGE2, and TNF-α genes regulating fever in LPS-stimulated RAW264.7 macrophages. The treatment of 3T3-L1 pre-adipocytes with TPDM6315 extracts during a differentiation to the adipocytes resulted in the decreasing of the cellular lipid accumulation in adipocytes. The ethanolic extract (10 µg/mL) increased the mRNA level of adiponectin (the anti-inflammatory adipokine) and upregulated the PPAR-γ in the TNF-α induced adipocytes. These findings provide evidence-based support for the traditional use of TPDM6315 as an anti-pyretic for fever originating from inflammation. The anti-obesity and anti-inflammatory actions of TPDM6315 in TNF-α induced adipocytes suggest that this herbal recipe could be useful for the treatment of metabolic syndrome disorders caused by obesity. Further investigations into the modes of action of TPDM6315 are needed for developing health products to prevent or regulate disorders resulting from inflammation.

RESUMO

Narrowband-ultraviolet B (NB-UVB) has been used to treat skin diseases such as psoriasis. Chronic use of NB-UVB might cause skin inflammation and lead to skin cancer. In Thailand, Derris Scandens (Roxb.) Benth. is used as an alternative medicine to nonsteroidal anti-inflammatory drugs (NSAIDs) for low back pain and osteoarthritis. Therefore, this study aimed to evaluate the potential anti-inflammatory effect of Derris scandens extract (DSE) on pre- and post exposed NB-UVB human keratinocytes (HaCaT). The results indicated that DSE could not protect HaCaT from cell morphology changes or DNA fragmentation and could not recover cell proliferation ability from the NB-UVB effects. DSE treatment reduced the expression of genes related to inflammation, collagen degradation, and carcinogenesis, such as IL-1α, IL-1ß, IL-6, iNOS, COX-2, MMP-1, MMP-9, and Bax. These results indicated the potential use of DSE as a topical preparation against NB-UVB-induced inflammation, anti-aging, and prevention of skin cancer from phototherapy.

RESUMO

This study aimed to determine the mimosine level and examine the male reproductive toxicity effects of Leucaena leucocephala (LL) shoot tips plus young leaf extract. Mimosine level in LL extract was determined by thin layer chromatography before administration in animals. Male rats were divided into control and LL (1,500 mg/KgBW) groups (n = 6). After 60 days of experiment, serum sex hormones, sperm quality, and testicular histopathology were assayed and observed. Malondialdehyde (MDA) level and expressions of steroidogenic acute regulatory (StAR) and phosphorylated proteins in testicular lysate were examined by western blotting. Results showed that mimosine levels in LL extract was 17.35 ± 1.12 % of dry weight. LL significantly decreased FSH & LH levels, sperm qualities, and seminiferous tubule diameter compared to the control (p<0.05). Seminiferous tubular atrophies, germ cell sloughing, and degenerations were observed in LL group. In addition, testicular MDA level and StAR protein expression were significantly decreased in LL group. LL extract could increase the expression of a 50 kDa phohorylated protein in testicular lysate. In conclusion, LL extract has mimosine and reproductive toxicity effects on males.


Este trabajo tuvo como objetivo determinar el nivel de mimosina y examinar los efectos de la toxicidad reproductiva de los brotes de Leucaena leucocephala (LL), más el extracto de hojas jóvenes, en ratas macho. El nivel de mimosina en el extracto de LL se determinó mediante cromatografía en capa fina antes de la administración en animales. Las ratas se dividieron en grupos de control y LL (1,500 mg / kgBW) (n = 6). Después de 60 días, se analizaron y observaron las hormonas sexuales séricas, la calidad de los espermatozoides y la histopatología testicular. A través de Western Blot se examinaron el nivel de malondialdehído (MDA), las expresiones de reguladores agudos esteroidogénicos (StAR) y las proteínas fosforiladas en el lisado testicular. Los resultados mostraron que los niveles de mimosina en el extracto de LL fueron 17.35 ± 1.12 % del peso seco. LL disminuyó significativamente los niveles de FSH y LH, la calidad de los espermatozoides y el diámetro de los túbulos seminíferos en comparación con el control (p <0,05). Se observaron atrofias en los túbulos seminíferos, desprendimiento de células germinales y degeneraciones en el grupo LL. Además, el nivel de MDA testicular y la expresión de la proteína StAR se redujeron significativamente en el grupo LL. El extracto de LL podría aumentar la expresión de la proteína fosforilada de 50 kDa en el lisado testicular. En conclusión, el extracto de LL tiene mimosina y efectos de toxicidad reproductiva en los hombres.

RESUMO

Although Momordica charantia (MC) has preventive effects on tissue injuries, antioxidant capacity and protective effect of MC pulp and peel (MCP) on valproic acid (VPA)-testicular damage have never been reported. Fresh MCPs were aqueous extracted and determined for antioxidant capacity and momordicine I level by HPLC. Male rats were divided into 5 groups (control, VPA (500 mg/kgBW), MCP20/40/ or 80 mg/kgBW+VPA). In 30 experimental days, animals were pretreated with different doses of MCPs for 20 days before VPA injection for 10 consecutive days. Sperm concentration, testosterone hormone, and testicular histology of all groups were investigated. Expressions of testicular tyrosine phosphorylated and steroidogenic acute regulatory (StAR) proteins were examined by Western blot. Results showed that MCP contains TPC (39.24±0.65 ug/mg garlic acid), antioxidant capacities (FRAP=33.08±0.21 ug/ mg ascorbic acid equivalent, IC50 of DPPH=389.8±3.20 ug/ml), and momordicine I (404.9 mg/g MCP). Sperm concentration in MCP80+VPA group was increased as compared to VPA group. Testosterone level in MCP treated groups was significantly increased. MCP protected testicular damage and could prevent the decrease of StAR and a 50-kDa phosphorylated protein expression in VPAtreated testis. In conclusion, MCP has antioxidant activities and can prevent male reproductive toxicity in VPA-induced rats.


A pesar que la Momordica charantia (MC) tiene efectos preventivos sobre las lesiones en los tejidos, capacidad antioxidante y un efecto protector de la pulpa y la cáscara de MC (CMC) sobre el ácido valproico (AVP), aún no se ha informado efectos sobre el daño testicular. Las CMC frescas fueron extraídas de forma acuosa y se determinó la capacidad antioxidante y el nivel de Momordicina I por HPLC. Las ratas machos se dividieron en 5 grupos: control, AVP (500 mg/kg de peso corporal), CMC20 / 40 / u 80 mg/kg de peso corporal + AVP . En 30 días experimentales, los animales fueron pretratados con diferentes dosis de CMC durante 20 días antes de la inyección de AVP durante 10 días consecutivos. Se investigó la concentración de espermatozoides, la hormona testosterona y la histología testicular de todos los grupos. Las expresiones de proteínas reguladoras agudas (StAR) fosforiladas con tirosina y esteroidogénicas testiculares se examinaron mediante inmunotransferencia de tipo Western. Los resultados mostraron que CMC contiene TPC (39.24 ± 0.65 ug / mg de ácido de ajo), capacidades antioxidantes (FRAP = 33.08 ± 0.21 ug / mg de ácido ascórbico equivalente, IC50 de DPPH = 389.8 ± 3.20 ug / ml) y momordicina I (404.9 mg) / g CMC). La concentración de esperma en el grupo MCP80 + AVP aumentó en comparación con el grupo AVP. El nivel de testosterona en los grupos tratados con CMC aumentó significativamente. La CMC protegió el daño testicular y pudo prevenir la disminución de StAR y una expresión de proteína fosforilada de 50 kDa en los testículos tratados con AVP. En conclusión, la CMC tiene efectos antioxidantes y puede prevenir la toxicidad reproductiva en ratas machos inducidas por VPA.

RESUMO

The aim of present study was to investigate the effect of Momordica cochinchinensis (Gag) aril (GA) aqueous extract on male reproductive system of streptozotocin (STZ)-induced hyperglycemia (HG) mice. GA were extracted with distilled water (DW) and analyzed for in vitro antioxidant capacities. ICR male mice were divided into 7 groups: 1) control, 2) DW, 3) GA 1000 mg/kg BW, 4) HG, 5) HG + glibenclamide, 6 and 7) HG + GA 500 and 1000 mg/kg BW respectively (7 mice/ group). In HG groups, mice were induced by STZ at single dose (150 mg/kg BW). They were treated for consecutive 35 days. All groups were compared for blood glucose levels, weights and histopathologies of reproductive organs, sperm concentration including testicular tyrosine phosphorylation protein patterns by Immuno-Western blotting. The results showed that GA processed antioxidant activities and could significantly decrease blood glucose levels and increase sperm concentration in HG mice. Moreover, GA could change the density of a testicular 70 kDa protein in HG-GA groups. In conclusion, GA extract could improve hyperglycemia and male reproductive damages in STZ-induced HG mice.


El objetivo de este estudio fue investigar el efecto del extracto acuoso de Momordica cochinchinensis (Gag) aril (GA) en el sistema reproductor masculino de ratones hiperglucémicos inducidos por estreptozotocina (STZ). GA fue extraída con agua destilada (DW) y se analizaron las capacidades antioxidantes in vitro. Ratones ICR machos fueron divididos en 7 grupos: 1) control, 2) DW, 3) GA 1000 mg / kg PC, 4) HG, 5) HG + glibenclamida, 6 y 7) HG + GA 500 y 1000 mg / kg PC, respectivamente (7 ratones / grupo). En los grupos HG, los ratones fueron inducidos con STZ en dosis única (150 mg / kg BW). Fueron tratados durante 35 días consecutivos. En todos los grupos se compararon los niveles de glucosa en sangre, los pesos y las histopatologías de los órganos reproductores, la concentración de espermatozoides, incluídos los patrones testiculares de proteínas tirosina fosforilada por Inmuno-Western blot. Los resultados mostraron que GA procesaba actividades antioxidantes y podían disminuir significativamente los niveles de glucosa en sangre y aumentar la concentración de espermatozoides en ratones HG. Además, GA podría cambiar la densidad de una proteína testicular de 70 kDa en grupos HG-GA. En conclusión, el extracto de GA podría mejorar la hiperglucemia y los daños reproductivos masculinos inducidos por STZ en ratones HG.

RESUMO

This present study was designed to isolate the compounds of Memecylon edule. The chemical compounds were purified by chromatographic methods and their structures were established on the basis of spectroscopic analyses (UV, MS and NMR). The major isolated compounds were tested for anti-inflammatory activity. The methanolic extracts of M. edule leaves gave a new compound 2-butanone 4-glucopyranoside 6'-O-gallate (1) with eight known compounds, namely, 3,3'-di-O-methylellagic acid 4-O-ß-d-glucopyranoside (2), epigallocatechin-3-O-gallate (EGCG) (3), (2R, 3R)-dihydromyricetin-4'-ß-d-glucopyranoside (4), myricetin-3-O-α-l-rhamnopyranoside (5), benzyl-(6-O-α-L arabinofuranosyl) O-ß-d-glucopyranoside (6), benzyl-(6-O-α-l-rhanmopyranosyl) O-ß-d-glucopyranoside (7), 2-phenylethyl-(6-O-ß-d-apiofuranosyl)-O-ß-d-glucopyranoside (8) and methyl benzoate 2-(6-O-α-l-rhamnosyl)-O-ß-d-glucopyranoside (9). All compounds were isolated for the first time from this plant. The major compounds (2, 3 and 5) exhibited significant anti-inflammatory activity. In conclusion, M. edule was recognised to be a good source for phenolic compounds and these compounds may contribute to anti-inflammatory activity of the extract.

RESUMO

This study aimed to determine the antioxidant capacity of the Leucaena leucocephala aqueous shoot tips plus young leaves (LL-spl) extracts among three different fractions (LL-spl 10, 20, and 40 min) and to examine its acute toxicity on male reproductive parameters. The amount of the total phenolics in LL-spl extract was determined using a Folin-Ciocalteu reagent method and its antioxidant capacity was analyzed using 1, 1-diphenyl l-2-picrylhydrazyl radical scavenging and ferric reducing antioxidant powder methods. The LL-spl extract fraction with highest antioxidant capacity was used in animal treating. Male rats were divided into three groups (n= 5); control and groups treated with LL-spl 400 and 600 mg/Kg body weight for consecutive 40 days. The results showed that the LL-spl 40 min fraction possessed the highest antioxidant capacity. In addition, the LL-spl 400 and 600 groups showed no differences in weights of body, testis and epididymis, serum testosterone levels, and expression of testicular steroidogenic acute regulatory (StAR) protein. Significantly, LL-spl extract reduced the weight of seminal vesicle, sperm concentration, and seminiferous diameters compared with control. Moreover, LL-spl extract had adverse effect on testicular histology in inducing of seminiferous atrophy and degeneration including dilated blood vessels in interstitial tissue. It was concluded that although LL-spl extract possessing antioxidant capacity, in short term consumptions, it could be toxic to some male reproductive organs especially damaging testicular tissues.


El objetivo fue determinar la capacidad antioxidante del extracto de brotes acuosos con hojas nuevas de Leucaena leucocephala (LL-spl) en tres fracciones diferentes (LL-SPL 10, 20 y 40 min), además de examinar su toxicidad aguda sobre los parámetros reproductivos masculinos. Se determinó la cantidad de los fenoles totales en el extracto de LL-spl utilizando un método reactivo de Folin-Ciocalteu. La capacidad antioxidante se analizó por medio de 1-difenil-2-picrilhidracilo y/o métodos de reducción férrica de la capacidad antioxidante. La fracción de extracto LL-spl con mayor capacidad antioxidante fue utilizada en el tratamiento de los animales. Ratas macho fueron divididas en tres grupos (n= 5): el control y los grupos tratados con LL-spl 400 y 600 mg/kg peso corporal por 40 días consecutivos. El resultado mostró que la fracción LL-spl 40 min poseía la mayor capacidad antioxidante. Además, los grupos 400 y 600 LL-spl no mostraron diferencias según el peso corporal, testículos y epidídimo, niveles de testosterona y la expresión de proteínas testiculares. El extracto de LL-spl redujo de manera significativa el peso de la vesícula seminal, la concentración de espermatozoides y los diámetros de los túbulos seminíferos en comparación con el control. Por otra parte, el extracto de LL-spl tuvo un efecto adverso sobre la histología testicular por la inducción de atrofia y degeneración de los túbulos seminíferos, incluyendo a vasos sanguíneos dilatados en el tejido intersticial. Si bien el extracto LL-spl posee una capacidad antioxidante, ésta podría ser tóxica en el consumo a corto plazo para algunos órganos reproductores masculinos y especialmente dañino para los tejidos testiculares.

RESUMO

An extract of Zingiber cassumunar Roxb. (ZC) was encapsulated in niosomes of which a topical gel was formed. (E)-4-(3',4'-dimethoxyphenyl)but-3-en-1-ol or compound D detected by a gradient HPLC was employed as the marker and its degradation determined to follow zero-order kinetics. Niosomes significantly retarded thermal-accelerated decomposition of compound D in the gel (p < 0.05) but did not change the activation energy of compound D. Niosomes enhanced in vitro permeation rate of compound D from the gel. Topical applications of ZC noisome gel gave a faster change in tail flick latency than piroxicam gel and hydrocortisone cream (p < 0.05) while there were insignificant differences in anti-inflammatory activity up to 6 h using croton oil-induced ear edema model in mice (p > 0.05). Thus, encapsulation of ZC extract in niosomes enhanced chemical stability and skin permeation with comparable topical anti-inflammatory effects to steroid and NSAID.

RESUMO

Valproic acid (VPA), widely used in treating epileptic patients, can damage reproductive parameters causing male infertility. This study aimed to investigate protective effect of Phyllanthus emblica L. branch (PE) extract on rat testicular damage induced with VPA. Male rats were divided into 6 groups (control, VPA, 250 mg/kgBW PE only, and 50, 100, 250 mg/kgBW PE+VPA, respectively). Animals were pretreated with PE for 23 days and co-administered with VPA for 10 days before all reproductive parameters were determined. The results showed all doses of PE significantly protected the decrease testicular weight and testosterone level in VPA rats. PE significantly improved the decrease sperm concentration in VPA treated rats. Moreover, testicular histology of PE+VPA groups showed declining of testicular histopathologies as compared to VPA group. Therefore, it seems that PE branch extract can prevent testicular damages including male reproductive parameters in rats induced with VPA.


El ácido valproico (AVP) es utilizado frecuentemente en el tratamiento de pacientes epilépticos y puede dañar los parámetros reproductivos que causan la infertilidad masculina. Este estudio tuvo como objetivo investigar el efecto protector de la rama Phyllanthus emblica L. (PE) sobre el daño testicular de ratas inducidas con AVP. Ratas machos fueron divididas en 6 grupos (control, AVP, PE 250 mg/kg peso corporal, APV+ PE 50, 100, 250 mg/kg peso corporal, respectivamente). Los animales fueron pretratados con PE durante 23 días y se administró AVP durante 10 días antes de medir todos los parámetros reproductivos. Los resultados mostraron que todas las dosis de PE protegen significativamente el peso y los niveles reducidos de testosterona testicular en ratas con AVP. El extracto de PE mejoró significativamente la concentración de espermatozoides en ratas tratadas con AVP. Por otra parte, la histología testicular de los grupos PE+AVP mostró disminución de la histopatología testicular en comparación con el grupo tratado sólo con AVP. Por lo tanto, parece que el extracto de la rama PE puede prevenir daños testiculares incluyendo los parámetros reproductores masculinos en ratas inducidas con AVP.

RESUMO

The activity of an aqueous extract of Prasaplai, a Thai traditional medicine, was studied on the isolated rat uterus in the oestrus stage. The results showed that the extract inhibited the contraction induced by a submaximal dose of acetylcholine (2.04×10(-4) mg mL(-1)), oxytocin (1.54×10(-4) mg mL(-1)) and prostaglandin E2 (PGE2) (6.00×10(-4) mg mL(-1)). The inhibition was concentration-dependent and reversible by tissue washing. The IC50 of Prasaplai extracts expressed as milligram of powdered preparation per millilitre of perfusion solution for acetylcholine, oxytocin and PGE2 were 11.70, 10.00 and 5.75 mg mL(-1), respectively. These data reveal that Prasaplai has an antispasmodic effect against uterine contraction by different mechanisms and corroborate the traditional use in the treatment of dysmenorrhoea. Oral administration of single dose of the water extract, calculated as powdered Prasaplai up to 20 g kg(-1) in rats, showed no sign and symptom of acute toxicity, and no rat died even at the maximum dose.

RESUMO

AIM OF THE STUDY: To determine the anti-inflammatory, analgesic and antioxidant activities of the leaves of Memecylon edule Roxb. used traditionally in Thailand. MATERIALS AND METHODS: Hexane, (Hex), ethyl acetate (EtOAc), methanol (MeOH) and 50% methanol (MeOH50) fractions of the dry leaves were tested in vitro for their interleukin-10 production; the most active fraction was further studied in vivo for its anti-inflammatory and analgesic activities using the ethylphenylpropiolate (EPP)-induced mouse ear edema and the writhing test with mice. All fractions except Hex were tested for their radical scavenging activity towards 1'-diphenyl-2-picrylhydrazyl radical (DPPH). RESULTS: The EtOAc showed the highest stimulation for interleukin-10 production. In the EPP test, this fraction was significantly active 30 min after topical application at all doses used (0.5, 1.0, 2.0mg/ear); after 4h and at 1.0mg/ear EtOAc was slightly less active (inhibition 47.8%) than the reference, indomethacin, at the same dose (62.4%). At 200mg/kg orally, the EtOAc caused a significant inhibition of the writhing response by 56.6% which was like indomethacin at 10mg/kg. EtOAc, MeOH and MeOH50 exhibited radical scavenging activity. The order of IC(50) values was: ascorbic acid (9.1 microg/mL)>trolox (11.6 microg/mL)>MeOH (46.9 microg/mL)>MeOH50 (152.1 microg/mL)>EtOAc (1742.2 microg/mL). CONCLUSION: The results provide support for the traditional use of Memecylon edule leaves in relieving inflammation and pain.

RESUMO

Prasaplai is a Thai traditional preparation composed of twelve ingredients; during storage three newly emerging compounds were detected by HPLC. Their structures were established as the new (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-yl linoleate, (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-yl oleate and the known (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-yl palmitate on the basis of spectral data and chemical evidence. The artificial esters were already observable after one day of storage of the freshly prepared dry mixture, and steadily increased during a storage period of 30 days and more. A systematic search indicated that the three esters arose from the interaction of compounds contained in the rhizomes of Zingiber cassumunar and the seeds of Nigella sativa.
