Formulation and characterization of a green tea extract containing emulsion prepared with Abil®EM90 as a lipophilic surfactant
The purpose of this study was to formulate and develop a stable water-in-oil (W/O) emulsions containing the extract of the green tea leaves. Abil®EM90 was used as an emulsifier and effects of emulsifier ratios were optimized to obtain a stable emulsion without adding any preservative. For this purpose, 25 formulations were formulated initially and were kept at 25°C to choose the desired formulations for...

Alteration of renal function by potassium bromate (KBrO3): Protective effects of Launaea procumbens
Potassium bromate (KBrO3) is a nephrotoxin which causes renal oxidative stress and cancer in experimental animal. In the present study, nephroprotective effects of Launaea procumbensagainst KBrO3 induced renal function toxicity were determined. In this study, 24 male albino rats (180 to 200 g) were divided into 4 groups. Group I was given saline (1 ml/kg b.w., 0.85% NaCl) and dimethyl sulfoxide (DMSO) (1 ml/kg...

Kinetic study on leaching of fluorine from green tea
Kinetic behaviors of fluorine leaching from tea were studied. The leaching process of fluorine could be divided into initial fast stage and later slow stage. The duration of fast stage 1 depended on leaf particle size and temperature. The higher the temperature and the smaller the leaf particle size, the shorter the duration of initial fast stage. Based on the test results, a two-step infusion method was developed to...

Comparative anatomical studies on the two Stachys species (sect. Eriostomum, subsect. Germanicae) growing in Turkey
In this study, comparative anatomical studies on the two Stachys species (sect. Eriostomum, subsect. Germanicae) in Turkey were carried out on the plants collected from their type localities. These species are Stachys balansae Boiss. & Kotschy and Stachys carduchorum(R. Bhattacharjee) Rech.f. which are morphologically very similar to each other. Anatomical properties...

Aldosterone induces apoptosis via the Wnt signalling pathway
Evidence suggests that aldosterone (ALD) is involved in glomerular damage; however, it is rarely known whether ALD exerts a direct injurious effect on mesangial cells (MC). The objectives of this study were to determine the relationship between ALD and apoptosis, and investigate the cell signalling pathway by which ALD induces apoptosis. Rat MC were treated with ALD (10-8, 10-7 or 10-6 M) for 24 h. In some...
