The invention relates to methods for prevention and/or treatment of skin lesions caused by exposure to ultraviolet radiation. Exemplary condition that can be prevented or treated are actinic keratosis, dry skin, polymorphic light exanthema, photopathology, photo-allergy, solar atrophy, stria migrans, elastoma diffusum, X-ray dermatitis, gouty polychondritis and decubitis ulcer. The method employs application to the skin of a composition comprising a hydroximic acid derivative of the formula

Method for treating the pathological lesions of the skin that develop by ultraviolet radiation of the sunlight

A novel cosmetic composition comprising a known hydroximic acid derivative as the active ingredient, and conventional carriers of the cosmetic composition are disclosed. The cosmetic composition of the invention is suitable for the prevention and/or reduction of the photoaging processes of the skin exposed to UV radiation.

Cosmetic composition and a method for the prevention and/or reduction of the photoaging processes of the skin

Disclosed is a process for improving the efficiency of in vitro propagation and tissue cultivating by tissue culture of cultivated of plants which comprises treating the plants during micropropagation and/or subsequent planting with an aqueous solution of one or a mixture of substituted amides or one or a mixture of substituted diamides.

Plant tissue cultivation process

The invention relates to a plant growth regulating composition which contains as active agent a compound of general formula (I) ##STR1## wherein R.sub.1 and R.sub.2 can be identical or different and can stand for hydrogen, a C.sub.1-4 straight or branched alkyl group, cyclohexyl, phenyl, chlorophenyl, alkylphenyl, benzyl or alkylbenzyl group, or R.sub.1 and R.sub.2 can together with the N atoms form a heterocyclic ring. The growing of plants can be stimulated and the green weight can be increased to a significant degree by the treatment carried out with the composition of the invention.

Plant growth regulating method

The invention relates to new compositions for increasing the cold resistance of cultivated plants. These compositions contain as active ingredient at least one compound of the general formula (I), ##STR1## wherein n is an integer of 2 to 5 and R.sub.1, R.sub.2 and R.sub.3 each stand for hydrogen or C.sub.1-5 alkyl, or an acid addition salt thereof in an amount of 0.01 to 70% by weight, together with a conventional diluent and/or additive. The plants treated with the compositions according to the invention are more resistant to cold and frost.
