riorate, and their efforts are sometimes
rewarded by success. Among the various methods of empirical treatment of schizophrenia the following hold pride of place :?
(1) Pyrexial treatment. The production of fever in patients by injections of typhoid vac- cine, sterile milk, pyrifer sulfosin, Dmelcos vaccine, by inoculation of malaria, by diathermy or by any other means.
(2) Glandular products of various kinds, especially testicular, thyroid and ovarian extracts.
(3) Prolonged narcosis by various sedative
drugs such as somnifaine, soneryl, sodium
amvtol, nembutol, luminal, somnos, hypnol, and sodium evipan.
Prolonged narcosis by somnifaine is still in
vogue in England and on the Continent. Advocates of one or more of the above-stated
empirical methods of treatment of schizophrenia will not be found wanting, and no doubt these methods have achieved sporadic success and have caused a certain amelioration of symptoms, yet the results have not been such as to com- mend them universally for the routine treatment of schizophrenia. Moreover all the above methods of empirical treatment of schizophrenia were tried by me from time to time on the
schizophrenics of the Ranchi Indian Mental
Hospital, which is the largest and one of the most modern mental hospitals in India. The results of our successes and failures with these methods of treatment were fully stated in our annual reports of the hospital, and some with encouraging results were published in medical
journals. Recently to the vast armamentarium of the schizophrenic empirical treatment are
added the insulin hypoglycemic therapy by Dr. Manfred Sakel of Vienna and the epilepti- form shock therapy by the drug cardiazol by Dr. Ladislaus V. Meduna of Budapest. It is the writer's aim in this paper to describe in full his own experience of ' convulsive therapy' of
schizophrenia as evolved by Dr. Meduna. Since the introduction of
' insulin therapy ' in
schizophrenia by Dr. Manfred Sakel typical epileptiform attacks are frequently observed in patients undergoing this treatment. Both in Vienna and Munsingen (Switzerland) cases have been observed with such attacks during insulin treatment and it was reported that when an
epileptiform attack appeared it produced a
very favourable effect. Recently a case of status epilepticus during insulin treatment was recorded by Gillies (1937). Incidentally Dr. Hunter Gillies in this article has also men- tioned the work of Dr. Ladislaus V. Meduna. When I was in Budapest in 1935 I was invited by my friend and colleague Dr. Meduna to see his treatment of schizophrenia at the Royal Hungarian State Mental Hospital, Budapest. I was so impressed with all that I saw and more so with the good results obtained by Dr. Meduna by this treatment that I decided to try the treatment in my hospital on my return to India. I will describe in short the
322 THE INDIAN MEDICAL GAZETTE [June, 1938
theory and technique of Dr. Meduna's treat-
ment by cardiazol before I narrate my own
experience with this treatment. The theory.?Dr. Meduna for a long time held
a theory that there might be some biological antagonist to schizophrenia just as Hofrat
Professor Wagner-Jauregg found biological antagonism between malaria and neuro-syphilis. Dr. Meduna with this end in view made an ex-
haustive study of the literature on epilepsy and
schizophrenia and accidently he came across an article written by one of the Continental author- ities on epilepsy wherein the author had stated that epilepsy and schizophrenia are very seldom found in combination in one and the same
person. Dr. Meduna was very much impressed with this new knowledge and he made further studies on this line and was later convinced that
there was some biological antagonism between schizophrenia and epilepsy. For years he
carried out experiments, firstly on animals and later on patients, with various drugs to induce epileptiform fits and found that 25 per cent
camphorated oil solution given intramuscularly produced the best results. He obtained 10
remissions out of the first 26 cases of schizo-
phrenia treated by camphor injections, but later lie found that the tolerance to camphor with patients differed greatly and he was compelled to seek a more stable and reliable medicament for this purpose. Finally, he tried Knoll's cardiazol and the results obtained were highly satisfactory. Cardiazol (penta-methylene-tetra- zol) is generally known to the profession as a
water-soluble synthetic preparation having pharmacological effects similar to camphor, to
which it is distantly related to camphor chemi- cally. The dose given for inducing epileptiform fits is far in excess of the one usually prescribed in clinical practice of this useful drug, yet it has no injurious effect on the normal heart and is not cumulative in its action. I have no inten- tion in this article of entering into any discussion about the theory on which this treatment was evolved by Dr. Meduna, however fantastic it may appear. I am only dealing with the prac- tical side of it, viz, the results obtained by this treatment. Dr. Meduna claims to have obtained 40 to 50 per cent remissions in schizo- phrenics by this treatment.
Technique and dosage as evolved by Dr. Meduna.?Dr. Meduna starts the treatment by using a 10 per cent solution of cardiazol, com- mencing with an injection of 5 c.cm. and increasing each injection by one c.cm. until the fit is produced. Should 5 c.cm. induce a fit the dose for that particular patient is not increased. One may use a solution of greater strength but in any case Dr. Meduna suggests commencing with 0.5 gramme of cardiazol and if necessary increasing each successive dose by 0.1 gm. The intravenous route is always preferred but if this is not possible on account of the depth of the veins the injections may be given intra- muscularly the dose then being increased from
0.3 gm. to 0.5 gm. above the intravenous do?e; No definite plan can be laid down as to h?
g many injections are necessary for each case ^ they vary considerably in different patie1^' Some schizophrenics have shown full remissi^ with 3 or 4 injections and others have not ^ proved at all after 20 to 30 injections. ]A ever, Dr. Meduna suggests that no case sh?u ,
be given up as hopeless for this treat?^, without giving the patient the benefit of at le^ 20 such injections, or, to be more accurate,. ^ such convulsive shocks. Dr. Meduna has trie^ this treatment on a large number of cases ^ has obtained 40 to 50 per cent remissions

Contra-indications for treatment.?The ment is contra-indicated in acute bodily or chronic disease affecting the heart, bl??
vessels, lungs and kidneys.

his I ??e katatonic patient who had
murdered
r?ther and never admitted it before the
court or to anybody else suddenly one day after the fit made a frank confession of his crime and described in detail the scene of murder which when verified with the police report was found to be correct. On the other hand we tried to get a confession out of another patient who was also charged with murder and would not admit it, but we failed in this case.
(9) A katatonic with marked flexibilitas cera and mutism on the day of the fifth injection implored us not to give him the treatment and said that he would act and behave like a
normal person in every way. I gave him a
chance and he behaved very like a normal
person for two days but relapsed on the third and the treatment was continued in his case
and after a full course he showed a great im- provement in his katatonic condition.
(10) Three patients during the course of in-
jections twice showed conditions like larval
epilepsy or epileptic equivalents, i.e., their fits after a full dose of cardiazol (1 gm. in 10 per cent solution) were replaced by a condition of excitement almost amounting to furor which lasted for 15 to 30 minutes. On coming round the patients had no memory of their excitement and they showed complete amnesia of events, a point of great medico-legal importance.
(11) Some patients as soon as the drug was injected started coughing a little as if the drug had irritated their throats and they invariably went into fits. The cough is now regarded by us as an unfailing sign for the production of fits.
Dangers and complications.?I am glad to be able to state here that not a single case showed any dangerous symptom and I agree with the
findings of Dr. Meduna that the treatment is
perfectly free from any danger in selected cases. Four patients during fits had dislocations of shoulders which were soon put right when they were in the amnesic state and with proper care the trouble never recurred, although we sub-
sequently induced many fits in the same
patients. It is said that any hypnotic, especially mor-
phia, hyoscine, paraldehyde and sodium evipan, will counteract any dangerous symptoms produced by cardiazol. In our emergency tray these drugs were always kept ready for imme- diate use but we never had any occasion to use them.
Comments
We found in our series of cases that those
patients in whom severe fits were induced by the initial dose of 0.5 gm. of cardiazol for the first 8 to 10 injections showed better improve- ment than those in whose case the initial dose had to be increased in the first 4 or 5 injections to 1 gm.
(2) Rapidity of injections also plays a great; part in the induction of fits. We experimented
324 THE INDIAN MEDICAL GAZETTE [June, 1938
with large doses of stronger solution and injec- ted the dose very slowly and no fits were pro- duced but in the same patients the next day we gave 0.5 gm. dose at a speed of 1 c.cm. per quarter second and produced beautiful fits.
Our usual rate of injection is 5 seconds.
(3) The treatment is very simple and can be undertaken by any physician with a little know- ledge of the technique.
(4) It is true that the induction of epilepti- form fits in patients is not a very pleasant sight for onlookers but to the patients themselves it makes no difference as they become unconscious at the very onset of the fit and even on recovery they do not remember anything. In fact, they have complete amnesia of events. Patients
generally learn about the fits from other patients or the attendant staff, or at times after recovery from a fit they sometimes try to peep through the screen when other patients are being given the same treatment in their ward, although every effort is made to prevent the patients from getting the information.
This point was further elucidated by giving injections to one of the staff who volunteered to undergo this treatment in the cause of science. He also informed us that he had no
knowledge of what happened from the time the needle was introduced into his vein until he recovered his senses. He further said that he suffered no pain or felt no shocks and did not remember anything (complete amnesia of events).
(5) On the days when n,o cardiazol is given, patients are allowed to attend the occupational therapy classes and to take part in all daily activities of the hospital life.

June, 1938] TREATMENT OF SCHIZOPHRENIA ; DHUNJIBHOY 325
Table III shows that schizophrenics are curable in their early stages and the earlier the treatment is applied the better are the results, rhe majority of the cases who improved under treatment were early cases as shown in column 4 of table III. All the discharged patients have still maintained the improvement. Case 11 was wrought on a stretcher as an acute case ot Catatonia. On admission he could neither walk ??r talk, he refused to take his food and was *ed
nasally for a few days. After the third Injection of cardiazol he began to talk and took lls, food and after the tenth injection he became quite normal and began to walk. He was given ^ full course of 30 injections?27 or 0.5 gin. and ?r 1 gm> He improved very much in his Cental and physical health and was discharged lls fully recovered by the board of visitors. In
opinion this was a great success for cardiazo the case on admission appeared to be qui e n.?peless. Of the 15 improved cases 5 have *lnce relapsed after maintaining the improve- ment for a varying period from 2 to 5 months, ue remaining 10 cases have still maintained le improvement and are now working satis-
factorily in the hospital. By improvement, ^e.an those cases who before the treatment were i^sy, attitudinistic, negativistic, showing flexi- Ujtas cera and a few of them were partly 1Xlng a vegetative existence, improved alter ardiazol injections inasmuch as they began to ;fke an interest in their surroundings and in uemselves and are now attending the occupa-
therapy departments in the hospital, to which place they refused to go and work before, ourteen cases showed no improvement at a spite of the full course of 20 to 30 injections rp.Ven to them and they remained stationary. le
results of the experiment can be called en- gaging and the results in percentages were as follows
full remissions ? ? 31 per cent Improved ? ? 36 ,, ?
Stationary ? ? 33 >>
All the recovered cases were given four ? Ejections after recovery as recommended
tn ? ,' Meduna. In all our cases we were able nf lnc^uce the first fit at an initial dose of 0.5 gm.
cardiazol and in most cases this initial dose J! , later and we had to increase the dose in i- uations up to 1 gm. One gramme of car- lazol never failed to induce fits in all our
w le^s hence our initial dose for every patien as 0-5 gm. and maximum dose 1 gm.
e diagnostic aid of cardiazol in suspected cases of epilepsy
-^r. Schonmehl (1936) gives an interesting ccount of cardiazol as an aid to diagnosis in ^pected cases of epilepsy and other allied
?uditions. Durine his experiments on stuporous cK?nditions in epilepsy he found that fits could Je Educed in epileptics by very small doses of
cardiazol (0.5 to 3 c.cm.). We also experi- mented with our epileptic patients with small doses of cardiazol which failed to induce fits in our schizophrenic patients but induced severe
fits in epileptic patients. Doses given by us
were from 1.5 c.cm. to 3 c.cm. Dr. Meduna states that to produce epileptic fits in a normal healthy individual the dose required would be approximately 10 c.cm. only. In schizophrenic cases we could not induce fits below the mini- mum dose of 0.5 gm. It therefore proves that the small doses of cardiazol can produce con- vulsive fits in epileptics only. One of the
patients of Dr. Schonmehl had been successful in convincing the authorities when applying for a motor driving licence that he was not a
sufferer from epilepsy. He was brought to
Dr. Schonmehl who injected a small dose of cardiazol and induced severe fits in him and thus confirmed the diagnosis. We had a patient in the female section who was a suspected case of epilepsy; no medical officer had seen her in a fit because she had occasional fits only during the night and by the time a medical officer was called the patient had recovered from the fit, as she was suffering from a mild type of epi- lepsy. We therefore decided to use cardiazol in this case and injected 2.5 c.cm. of cardiazol; the patient went into a fit at once. We could not carry out further experiment by cardiazol in this direction as we had no other suspected cases of epilepsy.
Summary (1) The problem of schizophrenia is very
briefly described with its empirical treatment. (2) Forty-two cases of schizophrenia were
treated with cardiazol after the method of Dr. Meduna; the technique fully described.
(3) The results of the experiment were en-
couraging. (4) Cardiazol treatment appears to be per-
fectly safe in selected cases and is well worth a trial in all cases of schizophrenia, and more so
in the katatonic and hebephrenic varieties.
(5) It is free from any dangerous complica- tions and does not require such constant medical and nursing attention as in the case of insulin therapy. I would certainly give this treatment preference over insulin therapy. Acknowledgments.?We are indebted to
Messrs. A. G. Knoll for the free supply of car- diazol powder for our experiment.
I should like to acknowledge my appreciation of the valuable help I have received from the medical and nursing staff of the hospital.
I am also indebted to my friend and col- league, Dr. Gyarfas Kalman of Budapest, for the translation of Dr. Meduna's paper.
