Antidermatophytic Activity of the Fruticose Lichen Usnea orientalis.

In the present study, the new biological sources in the form of lichen Motyka was screened for its antidermatophytic potential. Six species of dermatophytes were chosen on the basis of their prevalence for antidermatophytic assays, and the Clinical Laboratory Standard Institute (CLSI)-recommended broth microdilution procedure was used to detect the efficacy of extract against dermatophytes. Thin layer chromatography of lichen extracts reveals the presence of two secondary metabolites viz.

Exploration of anti-Malassezia potential of Nyctanthes arbor-tristis L. and their application to combat the infection caused by Mala s1 a novel allergen.

Background: Malassezia commensal yeasts along with multitude of antigens have been found to be associated with various skin disorders including Pityriasis versicolor (PV). Amongst them Mala s1, a 37 kDa protein has been proved to be a major allergen reacting with a large panel of sera. However, there exists no therapeutic alternative to combat such problems in form of plant based natural compounds.

Pharmaco-Phylogenetic Investigation of Methyl Gallate Isolated from Acacia nilotica (L.) Delile and Its Cytotoxic Effect on NIH3T3 Mouse Fibroblast.

Present exploration deals with the therapeutic perspective of methyl gallate isolated from the leaf extract of Acacia nilotica (L.) Delile in contrast to food-borne bacterial pathogen's viz., Escherichia coli, Klebsiella pneumoniae, Salmonella typhimurium, Pseudomonas aeruginosa and Staphylococcus aureus with their evolutionary succession.

Management of cosmetic embarrassment caused by Malassezia spp. with fruticose lichen Cladia using phylogenetic approach.

During anti-Malassezia screening of plants by CLSI broth microdilution method, Cladia aggregata (Swartz) Nyl. (family Cladoniaceae), a fruticose lichen from Sikkim (northeast Himalayan region), has been found effective at minimum inhibitory concentrations (mg/mL) of 2.72, 0.

Studies on antidermatophytic activity of waste leaves of Curcuma longa L.

During antidermatophytic screening of some essential oils, Curcuma longa L. exhibited the strongest antifungal activity, completely inhibiting the mycelial growth of ringworm, caused by the fungi- Microsporum gypseum and Trichophyton mentagrophytes. The essential oil from leaves of Curcuma longa was fungicidal at 2.

Parathyroid hormone gene polymorphism and sporadic idiopathic hypoparathyroidism.

The pathogenetic mechanisms involved in the development of sporadic idiopathic hypoparathyroidism are currently under investigation. Although autoantibodies against the calcium-sensing receptor (CaSR) have been implicated to play a role, these could be demonstrated in only 49% of a group of 51 patients with sporadic idiopathic hypoparathyroidism that we previously studied. Therefore, we investigated 49 of these patients further, regardless of their antibody status, and looked for mutations in the section of the PTH gene sequence that coded for prepro-PTH as well as the 3'-untranslated region (3'-UTR) of the gene, which is believed to be involved in the stability of its mRNA.

Parmelia cirrhatum: a potential source of broad spectrum natural antifungal.

During antifungal screening of some plants, the water extract of lichen, Parmelia cirrhatum was found to be most effective against tested pathogenic fungi at the range of 60-80 microL/mL concentrations. The extract showed heavy doses of inoculum potential at 80 microL/mL and the antifungal activity of the extract did not expire up to 24 months of storage. The extract did not showed any irritation on mammalian skin up to 10% concentration.
