Description

Zwiazki bizmutu, stosowane do leczenia kily, przewaznie w postaci soli kwasów or¬ ganicznych, posiadaja te wade, ze wskutek odbywajacej sie w tkankach hydrolizy wy¬ dzielaja sie kwasy silnie drazniace i powo¬ dujace bóle i przesieki. Równiez wolne od kwasów zwiazki bizmutu (Bi20^f BiO(OH) wywieraja szkodliwe wplywy uboczne.Chodzi tutaj prawdopodobnie o mechanicz¬ ne uszkodzenia tkanek wskutek silnego na¬ gryzania tych srodków, wedlug dotychcza¬ sowych sposobów bowiem nie mozna bylo otrzymac wymienionych polaczen zapomo- ca oliwy i podobnych srodków w postaci zawiesin;, które po zasifcrzyknleciu domie¬ sniowo lub podskórnie nie wywolywalyby szkodliwej reakcji.Stwierdzono, ze otrzymuje sie preparat, nadajacy sie znakomicie do wyzej wymie¬ nionego celu, suszac swiezo stracony wil¬ gotny wodorotlenek bizmutu Bi(OH)3 prziez usuwanie zen wodly zapomoca plóka- nia alkoholem, eterem lub podobnemi cie¬ czami. Otrzymuje sie w ten sposób bardzo lekki i delikatny proszek, który pod mi¬ kroskopem jest jednolity i który mozna bez trudnosci przerabiac z oliwa na bardzo drobnoziarniste zawiesiny. Analogicznie do doswiadczen Willstaitter'a nad innemi wo¬ dorotlenkami, równiez i w tym przypadku zapobiega sie chemicznym zmianom, po¬ wstajacym przy ogrzewaniu wodorotlenku w stanie wilgotnym. Doswiadczenia, doko¬ nane na zwierzetach i na ludziach w insty-tutach i klinikach uniwersyteckich, wyka- zialy, ze Wstezytówania te sa bezbolesne, ze nie w^l^ujs^po niólf ani przesieki, iani tez kinie stany zapalne lub szkodliwe dzialania uboczne, jak to stwierdzono przy uzyciu innych pmepairatów bizmutu, i ze równiez terapeutyczne dzialanie srodka otrzyma¬ nego wedlug wynalazku przy leczeniu kily jest znakomite. Otrzymany preparat na- dlaje sie równiez skutecznie db leczenia in¬ nych chorób, gdy wskazane jest stosowanie triuclnorozipuiSiZlczalnego, bardzo rozdrobnio¬ nego prepiaratu bizmutu, Pnzyklad. 18,4 kg tlenku bizmutu roz¬ puszcza sie w 401 kwasu azotowego (40°Be) i 40 1 wody na kapieli wodnej; po dodaniu dalszych 40 1 wody studzi sie powstaly roz¬ twór do zwyklej temperatury. Mieszajac wprowadza sie odsaczony roztwiór do mie¬ szaniny, .skladajacej sie z 300 1 amonjaku, o prawie 0,91 ciez. gat., i 2000 li wody.Po osadzeniu sie osadu odlewa sie ciecz 4 — 5 razy od zebranego osadu, a nastep¬ nie osad odsysa sie i plócze najpierw woda, potem alkoholem, a wreszcie eterem. Po wyparowaniu eteru otrzymuje sie produkt wi postaci delikatnego, lekkiego proszku, dajacy sie bez dalszego przygotowywania przerabiac na delikatne zawiesiny lub e- mulsje. Zamiast alkoholu uzyc mozna me¬ tanolu, acetonu i podobnych srodków, a za¬ miast eteru — chlorku etylu, chloroformu i podobnych srodków. PLThe bismuth compounds used in the treatment of syphilis, usually in the form of salts of organic acids, have the disadvantage that due to the hydrolysis of the tissues, acids are released that are highly irritating and cause pain and exudation. Also, acid-free bismuth compounds (Bi20-f BiO (OH) have harmful side effects. It is probably mechanical damage to tissues due to strong exposure to these substances, because according to the methods previously mentioned, it was not possible to obtain the above-mentioned combinations of oil and similar suspensions, which, if swallowed by intramuscular or subcutaneous injection, would not cause a harmful reaction. It has been found that a preparation is obtained which is perfectly suitable for the above-mentioned purpose by drying the freshly lost wet bismuth hydroxide Bi ( OH) 3 steps to remove the zen with water by staining with alcohol, ether or similar liquids, which gives a very light and fine powder which is homogeneous under a microscope and which can be easily processed from the oil into very fine-grained suspensions. By analogy with Willstaitter's experiments on other hydroxides, also in this case chemical changes, due to rising when heating the hydroxide in a wet state. Experiments on animals and humans in university institutes and clinics have shown that these anesthesia are painless, that they are not sore spots or exudates, and that they do not suffer from inflammation or harmful side effects. as has been found with other bismuth pmepairates, that also the therapeutic effect of the composition according to the invention is excellent in the treatment of syphilis. The preparation obtained can also be used effectively in the treatment of other diseases when it is advisable to use a tri-liquid, finely divided preparation of bismuth, Example. 18.4 kg of bismuth oxide are dissolved in 40 liters of nitric acid (40 ° Be) and 40 liters of water in a water bath; after addition of a further 40 liters of water, the resulting solution is cooled to its normal temperature. While stirring, the drained solution is introduced into the mixture, consisting of 300 liters of ammonia, of almost 0.91 weight. grade, and 2000 liters of water. After settling the sediment, the liquid is poured 4 - 5 times from the collected sediment, and then the sediment is sucked off and washed first with water, then with alcohol, and finally with ether. After the ether has evaporated, the product is obtained in the form of a fine, light powder, which can be processed into fine suspensions or emulsions without further preparation. Methanol, acetone, and the like may be used in place of alcohol, and ethyl chloride, chloroform and the like may be used in place of ether. PL
