BACKGROUND Methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI) in aqua is present in the European baseline patch test series at 100 ppm, whereas 200 ppm has been used in Sweden since 1986, in Spain in the late 1980s, and, in recent years, also in the United Kingdom and Ireland. OBJECTIVES With regard to MCI/MI, to investigate the data on contact allergy rates in dermatitis patients, ...

this study was carried out to investigate the effect of differentpreservative solutions to improve the keeping quality of tuberose (polianthes tuberosa cv. single). these preservative solutions (treatments) were: t1= 2% sucrose + 200 mg/l agno3, t2= 2% sucrose + 200 mg/l agno3 + 25 mg/l citric acid, t3= 2% sucrose + 300 mg/l hqs, t4 = 2% sucrose + 300 mg/l hqs+ 25 mg/l citric acid, t5= 2% sucro...

Male Lister rats, 200 250g at start were used; n = 14 (controls) and 13 (nicotine treatments),. They were trained to press levers to obtain alcohol, using the "sucrose fading" method of Grant and Sampson (1985), in which the animals learn to press a lever to obtain sucrose, then the solution is gradually changed to sucrose plus alcohol, then alcohol alone. The operant schedule used was a variab...

in this research, the effects of pulsing application of preservative solutions containing salicylic acid (100 and 200 mg/l) and methyl jasmonate (25 and 50 mg/l) and long period application of preservative solutions containing thymol (75 and 125 mg/l), menthol (75 and 125 mg/l) and eugenol (50 and 100 mg/l) on the maintain quality and extend vase-life of carnation cut flowers two tests were eva...

This study aimed to assess the effects of plant growth regulators (PGRs) on stock production mojave sage ( Salvia pachyphylla ) and ‘Avalanche’ cape daisy Osteospermum hybrid) that received foliar sprays following three PGRs: 200 400 ppm ethephon; 250 500 benzyladenine; 50 100 gibberellic acid 4 7 (GA 4+7 plus benzyladenine. Vegetative [height width index (GI)], number vegetative cuttings, fres...

Beef ground round inoculated with 1,000,000 spores of Clostridium botulinum 33-A per gram and containing various additives was exposed to gamma radiation. Spores were inactivated in samples (irradiated at 2.0, 2.5, and 3.0 Mrad) which contained sodium nitrate (1,000 ppm) plus sodium chloride (2.5%). Similar results were obtained when sodium nitrite (200 ppm) was substituted for sodium nitrate, ...

In a study of a possible syncarcinogenic effect of nitrosodimethylamine (NDMA) on sterigmatocystin ISTG) carcinogenesis. male rats were fed diets containing I 0 ppm STG. 10 ppm STG and I ppm NDMA. I ppm STG and IOppm NDMA or JOppm NDMA for 54 wk. Hepatic carcinomas developed in 75° o of the rats fed 10 ppm STG plus I ppm NDMA and in 53";, of those fed 10 ppm STG alone. The hepatic carcinomas de...

Lisianthus (Eustoma grandiflorum cv. ‘Mriachii Blue’) is one of the most important and marketable cut flowers in the world. However, a relatively limited vase life reduces its marketability. The aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of Lisianthus. For this purpose a factorial experiment based on a completely randomized desig...
