Ответ:

А. И. Куприн — рассказ «Изумруд». В этом рассказе писатель противопоставляет мир людей и мир животных. Изумруд — это скаковая лошадь, жеребец, выигравший скачки. Однако люди начинают оспаривать его первенство, утверждая, что лошадь «поддельная», «фальшивый рысак», требуют назад поставленные деньги. В финале Изумруд погибает (ему подсыпают отравленный овес). «Изумруд погибает вследствие коварства, корыстолюбия, алчности людей, но насколько он чище, совершеннее их! Невдомёк ему, разгорячённому блистательной победой в бегах, почему вокруг него поднялась суматоха, почему проверяют его клеймо и масть, почему звучат обвинения в мошенничестве, как невдомёк и то, почему у овса в чужой, незнакомой конюшне такой странно-непривычный вкус. И подлое убийство ранним утром, “когда все… спали”, не осознанное жертвой, отторгает убийцу, “большеголового, заспанного человека с маленькими чёрными глазками и тоненькими чёрными усами на жирном лице”, от рода человеческого, так безнадёжно уступающего животным в порядочности».

Invisible aids of man.

One need not have anything to do with medicine as such to know of the existence ol such powerful therapeutic agents as penicillin, Chloromycetin or streptomycin. These are all antibiotic substances, products of the life- activity of harmless microbes and small fungi which are lethal to other pathogenic fungi and microbes.

Only some 25 years ago medical men had almost no means for combating many diseases caused by microbes. Septicemia, for example was almost invariably taial. Antibiotic substances now cure such serious ailments as pneumonia, septicemia, meningitis, some forms of tuberculosis, tularemia and bubonic plague. During the war antibiotic substances saved the lives of thousands of wounded at the front.

The origin of antibiotics.

The antibiotic action of green mould, from which penicillin was subsequently obtained, was first discovered by the Russian physicians V.A. Manasscin and A.G. Polotebnov as far back as the 70's of last century. They not only established that mould retards the growth of microbes, but also successfully treated various kinds of ulcers with compresses for which mould was used. Although these Russian scientists were unable to extract the active element, penicillin, from the mould, owing to the low level of technical development their time, their discovery to a great measure paved the way for the subsequent use of penicillin as a therapeutic agent.

Thirty-five years later V.G. Tanakovsky, a Russian veterinary, published a paper on the results of his experiments which showed that a certain form of mould killed the microbe causing typhus. This expanded still further the range of microorganisms known to science whose vital activities are inhibited by substances produced by mould.

It is a self-evident fact that no science can develop without a sound theory summarizing and explaining its practical achievement. The science of antibiotics owes its developments first and foremost to the researches of Ily a Mechnikov, the outstanding Russian biologists, who discovered that certain types of bacteria arc dislodged by other in the intestines of both man and animals. The scientist gave an explanation of this highly interesting phenomenon. What happens is obviously a struggle among microbes with some species producing toxins that arc lethal to others. Working in the beginning of this century, Mechnikov was the first scientist to prove theoretically that it is possible to use the struggle among microbes in the interests of man.

Mechnikov, rightly called by his contemporaries “the great humanist”, devoted much effort to the problem of combating premature aging of the human organism. Man he said, is the victim of constant poisoning by toxic substances produces in his own intestines. It is here, in the digestive tract, that the enemies of the organism, putrefaction bacteria, constantly produce strong toxins which bring about premature old aee. But how is the harmful flora to be expelled from the organism? Could it not be done with the help of the micro-organisms themselves, by making use of the struggle going on among them? Mechnicov began to search for bacteria harmless to
man which, on being introduced into the intestines, could drive out the putrefaction microbes.

Investigations established that lactic bacteria, which cause the souring of milk, answer the purpose. In their presence putrefaction bacteria perish.

Mechnicov’s assistant, the Russian scientist Ignat Schiller, succeeded in proving this in practice.

Me found a medium in which lactic bacteria grew rapidly. This was lactose. He only had to feed mice with lactose and their intestines became populated with a pure culture of lactic bacteria. Experiments on man (lactose is perfectly harmless) confirmed that under the influence of sugar these bacteria as a rule drove out the putrefaction microbes from the intestines.
