PURPOSE To evaluate the effects of aroeira (Schinus terebinthifolius) ointment on skin wound healing in rats. METHODS Adult male rats (n=20) were divided into four groups of five animals each, as follows: G4, G7, G14 and G21, which corresponds to 4th, 7th, 14th and 21th days postoperatively. Each animal were made two incisions on the skin, including the subcutaneous tissue, in the right and l...

OBJECTIVE To describe the effects of long-term treatment with four different eye ointment bases (OBs) in cats. ANIMALS STUDIED Ten healthy cats. PROCEDURES The study was performed in two periods. Four different OBs were tested. Hundred grams of OB contained the following: OB-A: 35.17 g liquid paraffin (lp), 64.83 g white petrolatum (wp); OB-B: 10.03 g lp, 84.95 g wp 5.02 g lanolin; OB-C: 18...

Oil-in-water nanoemulsions are stable systems with droplet sizes in the 20-200 nm range. The physicochemical properties of these systems may be influenced by the addition of additives. Thus, the influence of ethoxylated (EL) and acetylated lanolin (AL) addition on the droplet size, pH values, electrical conductivity and stability of nanoemulsions was investigated. Then, effect of nano-emulsions...

In the course of their work on the carcinogenic action of oils and tars on mouse's skin, Twort and Twort (4,5) observed that addition of anhydrous lanolin often led to a reduction in neoplastic response. The inhibitory effect was greater than that obtained with benzene as diluent, and also occurred when lanolin was applied separately to the skin during the intervals between paintings. In view o...

The fact described in the preceding paper (9), tl'tat methylcholanthrene dissolved in anhydrous lanolin fails to produce a carcinogenic effect and does not even induce early skin changes such as epilation, epidermal hyperplasia, destruction of sebaceous glands, and diminution in the calcium and iron content of the epidermis, has been established in 4 experimental series comprising 312 mice. Sin...

In this paper the efficiency of a method for the separation and identification of pesticides in lanolin is presented. Theses pesticides belong to the organophosphorous and synthetic pyrethroids families. After the gel permeation chromatography, pesticides are separated from lanolin into two fractions corresponding to the two families, which simplify subsequent analysis by gas chromatography.

Lanolin is frequently used as a diluent for applying growth substances 'to plants. Its earliest use was described by LAIBACH (1). He applied unilaterally, to the first internodes of Phaseolus multiflorus seedlings, a lanolin paste containing the test substance. The presence of growth substances induced negative stem curvatures. Subsequently, Laibach and co-workers (2, 3) applied lanolin pastes ...

Painful and/or damaged nipples associated with breastfeeding are common and represent a challenge for both the persons experiencing nipple pain and/or trauma and for those providing treatment. However, evidence-based data has been insufficient to demonstrably minimize these common reasons for failure to initiate or continue successful breastfeeding. The aim of this study was to evaluate the eff...
