Iridoid glycosides consist the main bioactive constituents of Gardenia jasminoides Ellis (G. jasminoides), which is used alone or in combination with other medicine herbs for treatment of diabetes mellitus in China. This paper investigated for the first time comparative pharmacokinetics (PKs) of four unbound iridoids (including genipin, geniposide, gardenoside and geniposidic acid) in rat blood between healthy and type 2 diabetic groups with different disease progressions (9 or 13 weeks). Online microdialysis-ultra performance liquid chromatography-mass spectrometry (MD- UPLC-MS/MS) method was used after oral administration of iridoid extracts obtained from the fruits of G...

BACKGROUND: Inflammation is involved in various diseases; search for safe treatments is warranted. Anti-inflammatory effects of ethanol extract of Myrathius arboreus (EEMa) were studied in carrageenan-induced model, formaldehyde sub-acute-induced model, and in 48 h lipopolysaccharide-induced air pouch model of inflammation. EEMa membrane-stabilizing activities and anti-oxidant capacity were determined in vitro. METHODS: In the carrageenan model EEMa (125, 250, or 500 mg/kg), indomethacin (5 mg/kg), or vehicle 3 mL/kg was administered orally in rats (n=5)...

Ganoderic acid A (GAA), an active triterpenoid of the traditional Chinese herbal medicine Lingzhi, has been reported to exhibit antinociceptive, antioxidative, and anti-cancer activities. The present study aims to establish a sensitive and rapid UPLC-MS/MS method for studying the plasma and brain pharmacokinetics of GAA in rats. The analytes were separated on a C18 column eluted with a gradient mobile phase consisting of acetonitrile and 0.1% aqueous formic acid at 0.3mL/min. The eluate was monitored by a mass detector using an MRM (m/z, 515...

An adult diabetic male with three toes amputated on his right foot presented with an ulcer infection on his left foot, unresponsive to conventional antifungal oral medication for over two months. The ulcerated foot wound had a large impairment on the patient's quality of life, as determined by the Wound-QoL questionnaire. The compounding pharmacist recommended and the physician prescribed two topical compounded medicines, which were applied twice a day, free of charge at the compounding pharmacy. The foot ulcer infection was completely resolved following 13 days of treatment, with no longer any impairment on the patient's quality of life...

Eugenol is a hydroxyphenyl propene, naturally occurring in the essential oils of several plants belonging to the Lamiaceae, Lauraceae, Myrtaceae, and Myristicaceae families. It is one of the major constituents of clove (Syzygium aromaticum (L.) Merr. & L.M. Perry, Myrtaceae) oil and is largely used in both foods and cosmetics as a flavoring agent. A large body of recent scientific evidence supports claims from traditional medicine that eugenol exerts beneficial effects on human health. These effects are mainly associated with antioxidant and anti-inflammatory activities...

Swietenia macrophylla (SM) is a medicinally important plant found in tropical and subtropical regions of the world. The ethyl acetate fraction of the seeds of S. macrophylla (SMEAF) is reported to exhibit potent anticancer, antitumor, anti-inflammatory and antifeedant activities. Till date, there have been no studies reported on the acute oral toxicity profile of the ethyl acetate fraction of the seeds of SM. The objective of the present study was to determine the acute toxicity of SMEAF and evaluate the in-vitro neuroprotective activity of SMEAF using primary neuronal cell cultures...

ETHNOPHARMACOLOGICAL RELEVANCE: It is not always possible to correlate the "emic" terms to the "etic" ones during ethnopharmacological surveys, especially regarding those related to Culture-Bound Syndromes (CBS). Nevertheless, it is the role of ethnopharmacology to address these correlations, since they are the basis for the understanding of potential bioactives. AIM AND OBJECTIVES: This study reports the clinical manifestations and therapeutic resources used for the treatment of CBS among some riverine inhabitants of Brazilian Amazonia...

Phenylalanine ammonia lyase from Anabaena variabilis (Av-PAL) is a candidate for the treatment of phenylketonuria (PKU). However, Av-PAL shows its optimal pH at 8.5 and maintains only 70% of its highest activity when pH decreases to 7.3-7.4 (the condition of human plasma). The objective of the study was to shift its optimal pH by mutating surface amino acid residues which interact with the general base Tyr78. Based on the crystal structure and the online program GETAREA, we selected five sites: Asn69, Glu72, Glu75, Asn89, and Val90...

Jatropha dioica Sessé ex Cerv. is a medicinal plant credited with low cytotoxicity in vitro. Thus, the objective of this work was to evaluate the possible genotoxic and cytotoxic effect in vivo of the J. dioica aqueous extract by means of micronucleus assay in mouse peripheral blood. Four different J. dioica aqueous extract dose-units were evaluated (30, 60, 100, and 300 mg/kg). The extract was administered orally to male Balb-C-strain mice every 24 h during 5 days. Blood samples were taken at 0, 24, 48, 72, 96, and 120 h from the mouse's tail and were performed in duplicate extensions...

Emodin is the representative form of rhubarb, which is widely used in traditional Chinese medicine for the treatment of purgative, anti-inflammatory, antioxidative and antiviral, etc. Previous reports demonstrated that emodin glucuronide was the major metabolite in plasma. Due to the extensive conjugation reactions of polyphenols, the aim of this study was to identify the metabolites of emodin in rat bile and urine. Neutral loss and precursor ion scan methods of triple-quadrupole mass spectrometer revealed 13 conjugated metabolites in rat bile and 22 metabolites in rat urine, which including 4 phase I and 18 phase II metabolites...

As the temperature of extraction and processing could impact the biological effects of herbal extracts, which have wide chemical diversity, the aim of this work were to investigate the thermostability of herbal derivatives of the aerial parts of Sphagneticola trilobata, a reputed medicinal plant; to biomonitor its oral anti-hyperalgesic effect; and to elucidate the degradation pathways of the major components by UHPLC-ESI-QTOF-MS. The lipophilic markers (kaurenoic acid-KA) and hydrophilic markers [chlorogenic acids; measured as total phenolic compounds (PC), expressed in caffeic acid] were also monitored through a validated HPLC-UV methodology, suitable for quality control and stability studies...

Extemporaneous drug formulation is essential to provide optimal pharmaceutical care to veterinary patients. The need for this is exacerbated by the fact that commercially produced veterinary-specific products, without a human indication, require specialty veterinary manufacturing facilities and a new animal drug application process to gain marketing approval. This study examined the prescription patterns of extemporaneously compounded veterinary preparations in the compounding department at a large independent community pharmacy...

In recent years, there has been a growing interest in epithelial cell tissue culture, particularly oral mucosa and its application utilizing in vitro cell culture in medicine. This involves tests using animal models to better understand oral mucosa function, and the differences in its construction in various animal models. The use of buccal pouch mucosal cell culture provides insight into the processes of trans mucosal transport and regeneration of the oral epithelium. The processes associated with epithelium regeneration is the base for stem cell research and/or oral cancer investigation...

Bone regeneration is currently one of the most important and challenging tissue engineering approaches in regenerative medicine. Bone regeneration is a promising approach in dentistry and is considered an ideal clinical strategy in treating diseases, injuries, and defects of the maxillofacial region. Advances in tissue engineering have resulted in the development of innovative scaffold designs, complemented by the progress made in cell-based therapies. In vitro bone regeneration can be achieved by the combination of stem cells, scaffolds, and bioactive factors...

The strategy of formulating poorly soluble actives as nanosuspension has been explored by more than a thousand research papers, with some medicinal products for oral and intravenous use having reached the market or advanced clinical trials. Interestingly, there is a limited number of reports of nanosuspensions formulated for dermal and transdermal drug delivery. In the present work, a nanocrystals suspension of the fluorescent, water-insoluble dye Nile Red, is prepared through a media milling technique and exploited to characterize the fate of the nanosuspended drug when applied on the skin...
