摘要:
The invention relates to the field of medicine, and specifically to preparations for treating skin lesions, in particular viral, benign, precancerous and cancerous, non-metastasizing, dysplastic and inflammatory lesions of the visible mucous membranes, and also viral and fungal skin and nail lesions, and for correcting wrinkles and senile pigment blemishes, said preparations comprising solutions of complex compounds of salts of zinc and alpha-chlorocarboxylic acids of general formula [Zn(RCH2−xClxCOOH)n(H2O)4−n]+2.2[RCH2−xClxCOO]−, where R=alkyl, H or Cl, x=1-2 and n=0-4, in a corresponding alpha-chlorocarboxylic acid, wherein the content of zinc in the solution is 0.25-10.0% and the content of acid is 10-90%. The preparation may additionally contain an additive perfume, for example an ethyl ester of the corresponding alpha-chlorocarboxylic acid. The treatment method consists in that 2-5 doses of the preparation, which has been precooled to 10-15° C., are applied to the affected skin portion with a delay of 1-3 mins between the first and subsequent applications of the preparation. The preparations are stable on storage.

There are disclosed substituted lactones of the formula ##STR1## wherein A stands for --CH--CH.sub.2 X (X being Cl, Br or OH), --CHY--CHY-- (Y being Cl or Br), or ##STR2## and R.sup.1, R.sup.2 and R.sup.3 are the same or different radicals from the group of hydrogen and C.sub.1 to C.sub.10 alkyls, at least one of the radicals R.sup.2, R.sup.2 and R.sup.3 being such an alkyl radical, and process for making the same.
摘要:
A catalyst composition is manufactured by admixing a hydrocarbyl aluminum halide of a nickel compound of the formula (R.sub.1 COO)(R.sub.2 COO)Ni, where R.sub.1 is hydrocarbyl with at least 5 carbon atoms and R.sub.2 is haloalkyl of 1-3 carbon atoms. Olefins such as ethylene, propylene and butenes can be oligomerized, for example, dimerized and trimerized, with the above catalyst composition.

2,2-Difluoro prostanglandin E, F.sub..alpha., F.sub..beta., A, and B analogs are disclosed with intermediates and with processes for making them. These compounds differ from the prostaglandins in that they have two fluoro atoms at the C-2 position in place of the two hydrogen atoms at C-2 in the prostaglandins. These compounds are useful for a variety of pharmacological purposes, including antiulcer, inhibition of platelet aggregation, increase in nasal patency, labor induction at term, and wound healing.
