Cutaneous leishmaniasis (CL) is the most common parasitic disease transmitted by vectors in Iran. CL is endemic in many urban and rural parts of Iran and usually caused by two species of Leishmania as L. major and L. tropica transmitted to humans from parasite reservoirs by the bite of female sandflies. We report a case of ocular leishmaniasis with eyelid involvement presentation. The patient w...
In search for potential therapeutic alternatives to existing treatments for cutaneous Leishmaniasis, we have investigated the effect of Arnica tincture Ph. Eur. (a 70% hydroethanolic tincture prepared from flowerheads of Arnica montana L.) on the lesions caused by infection with Leishmania braziliensis in a model with golden hamsters. The animals were treated topically with a daily single dose ...
We report the case of a 78-year-old male Brazilian farmer, who presented with an extensive ulcer on the right foot that had an erythematous and raised border. This ulcer involved most of the right plantar region and had persisted for more than 40 years. Satellite erythematous papules and tumor-like growths were also seen on the right ankle. Extracutaneous involvement was not found. Light micros...
The objective of this study was to determine the effect of 42-day ZEN intoxication on the presence of Ca2+ in selected ovarian cells from beagle bitches, using the potassium pyroantimonate (PPA) method. Samples were collected from 30 clinically healthy, pre-pubertal, genetically homogeneous animals. The bitches were divided into three groups of 10 animals each: experimental group I--50 microg Z...
Potassium pyroantimonate, when used as fixative (saturated or half-saturated, without addition of any conventional fixative) has been demonstrated to produce intracellular precipitates of the insoluble salts of calcium, magnesium, and sodium and to preserve the general cell morphology. In both animal and plant tissues, the electron-opaque antimonate precipitates were found deposited in the nucl...
Recent biochemical studies indicate a significant role for sodium ions in nuclear metabolism. Protein and nucleic acid syntheses in the nucleus depend upon sodium, apparently through a stimulating effect of this cation on the transport of amino acid, purine, and pyrimidine into the nucleus (1). The nuclei of avian erythrocytes and calf thymocytes appear to contain higher sodium concentrations t...
Structure, electrochemical, magnetic and resonance properties of new layered antimonate Li(4)FeSbO(6) were comprehensively studied using powder X-ray diffraction, cyclic voltammetry, magnetic susceptibility, heat capacity, electron spin resonance and Mössbauer spectroscopy. In the crystal structure the iron ions form the triangular network within (LiFeSbO(6))(3-) layers alternating with nonmagn...
