Of eosinophilias that we often encounter clinically, we selected two of the most representative ones, namely, hookworm diseae and bronchial astma, for our present sternal bone-marrow tissue culture, and studied the movement patterns and wandering capacity of eosinophils. As the results, even in those eosinophils that show no significant change other than the increase in number in ordinary stained-smear specimens of peripheral blood or bone marrow, it has been clarified that, when observed under living condition, they reveal a picture specific to individualistic behaviors according to diseases. Therefore, it can be assumed that in the pathologic condition what is known as eosinopilia not only eosinophils increase in number but also qualitative changes of eosinophlils specific to each disease are brought about, and consequently these specific changes are reflected on the movement patterns of the eosinophil.

By physically destroying typhoid bacilli and centrifuging at a high speed, an insoluble granular fraction (P1) and soluble fraction (S1) were obtained. Chemical and enzymologic properties of these substances as well as their influences on the protective ability against infection were studied; and the following results were attained: 1. P1 contains an extremely small amount of proteins when compared with S1. 2. The enzymologic activity of P1 is entirely different from that of S1. In P1 the respiratory enzyme system of only lactate and succinate is localized. 3. Although both P1 and S1 possess the antibody-producing ability in serum of rabbit to the same high degree, P1 imparts to mice a markedly high protective ability against infection. 4. By the heat-treatment of P1 its antigenicity is lost at the same time.

In our department we have been placing a special emphasis on the treatment and study of rheumatoid arthritis, and during the last four years we have handled about 1,600 cases visiting our outpatient clinic and approximately 100 hospitalized cases. Our experiences with these patients are only what might be called an introductory phase in the study and treatment of rheumatoid arthritis when compared with those in Europe and America. In estimating the incidence of rheumatoid arthritis in Japan from various available data, although it would not reach the level of England and U.S.A., it will be about 100 cases per 100,000 population, matching more or less the incidence in the northern Europe. As regards sex and the predisposing age we find no great difference from those in Europe and America. One striking difference that we find is the fact that patients in our country have very little resistance against salicylic acid drug used in treatment. Therefore, it is unreasonable to expect a good anti-inflammatory action by administering a large dosage of 5-10g of such a drug as aspirin per day. It must be limited within a comparatively small dosage of 1.0 to 2.0 g or with concomitant administration of prednisolone and aspirin in the hope of utilizing its analgesic effect. Furthermore, it is not feasible to introduce the results of studies made in Europe and America on the salicylic drug and its prescription all of them showing the concentration in blood 35 mg%, which is on the borderline of intoxicating dosage. This is only one example, and with some more experiences we shall undoubtedly encounter many dissimilar points. Therefore, it is essential that rheumatology specific to Japan needs to be established.

Papanicolaou's smear test is a method based upon the morphological study of the cancer cells exfoliated from the epithelium, whereas T.P.T. is a method for examining the intracellular metabolism, the glycolysis, by a supravital staining of the cancer cells. The latter, therefore, can be called as a cytochemical diagnosis. Since, by the T.P.T. method, even a beginner can obtain the result of approximately 80% in correct and the skilled ones as high as 95%, the clinical diagnosis can be made all the more accurate by using Papanicolaou's test in combination with T.P.T. method. As for the entity of these granular cells, there remains a room for discussion, but Misonou feels that Cell Type A arises from necrobiosis of the carcinomatous tissues while Type B would be a certain wandering cell. This reaction, however, should not be employed to the cases in the puerperium, because the similar cells are exfoliated from the puerperal uterus. Thus, I can say that the T.P.T. is not a specific reaction to cancer. From this study, I wuld recommend T.P.T. as a method that is quite simple and is servicable for saving a great deal of effort and time on the part of clinicians, and I would like to encourage you to use it as one of tools for the diagnosis of carcinoma of the uterus, especially for an early diagnosis.

In our studies on the hypotensive effect of Diamox by intravenous injection, we have arrived at the following conclusions. 1. Ocular tension falls and the flow of aqueous humor becomes sluggish. 2. Diamox inhibits the activity of carbonic anhydrase, and the concentrations of HCO3-, K+, Cl- and glucose are markedly altered. 3. Protein increases both in blood and aqueous humor, but no change in protein fraction can be observed in blood. 4. Diamox in no way affects the metabolism. 5. It seems that Diamox brings about the change in the specific gravity of blood, making the latter either more diluted or more concentrated. From these, we conclude that the mechanism of the loweing of ocular tension by Diamox seems to lie in the fact that it inhibits the activity of carbonic anhydrase, and that consequent alteration in the concentrations of HCO3- and other ions accompanied by the change in osmotic pressure as well as a slight decrease of water in tissue all bring about the fall in the ocular tension. However, Diamox seems to have nothing to do with aqueous humor in so far as active transport or permeability are concerned.

Effects of stimulation of the small intestine upon the gastric, small intestinal and colonic motility have been studied in dogs. The results are summarized as follows. 1. The movements of the stomach, small intestine, and proximal colon are always inhibited by the distension or the contracture of the muscular coats of the small intestine but no responses are produced by a mechanical or chemical stimulation of the mucosa; and those of the distal colon are in most cases also inhibited, whereas in rare instances are they augmented. 2. The afferent impulses are transmitted through the great and small splanchnic nerves and the lumbar sympathetic nerves to the inhibitory as well as the excitatory (pelvic nuclei) centers of the intestinal movements located within the spinal cord, whereas the vagal nuclei remain unaffected. The efferent impulses are transmitted through the thoraco-lumbar sympathetic nerves as well as through the pelvic nerves. The latter are involved in the augmentative effect produced in the distal colon. 3. The threshold producing the extrinsic muscular reflex is higher than that eliciting the intrinsic muscular reflex.

Judging from our vital observation conducted mainly by tissue culture, it was firmly demonstrated that ascitic phagocytes are not histiocytes but they are the cells closely related to monocytes and that the sites of the genesis are the milky spots of the greater omentum. The milky spots are most possibly the remnants of the mesenchymal hematopoiesis of the embryonic stage.

In Japan, laryngofissure technique applied for the larynx cancer made its debut comparatively late, as compared with that in Europe and America. Namely, the laryngofissure was first used in the treatment of larynx cancer in 1931 by Prof. F. Tanaka and that was the first time this technique had ever been used in Japan, as far as in author's knowledge. This author had a good fortune to witness that first operation as his assistant.

An improved chromatographic method for the analysis of sugar phosphates and nucleotides presented in the previous paper was applied on the analysis of the metabolites of fructose produced by the action of hexokinase in some tissues in vitro, and the excellency of this method was demonstrated. The results showed that by this method the metabolites of the sugar in its early stage of catabolism can be analysed very easy and exactly and estimated quantitatively as well, giving no inconsistency with the results presented by the routine method.

In our study on the influences of various hormones and various endocrines on the megakaryocyte function by means of bone-marrow tissue culture, we obtained the following. 1. In the repeated administration of ACTH, cortisone, testosterone, progesterone, or thyroxin to guinea pigs, these hormones accelerated the megakaryocyte function, whereas estradiol on the contrary diminished the function. 2. The removal of such endocrines as the pituitary, adrenal, thyroid or testicles will diminish the megakaryocyte function, while removal of the ovaries accelerates it. 3. For the megakaryocytes in the hypophysectomized rats, ACTH acts most effectively to restore their function, followed by cortisone and pulverized thyroid, while testosterone has hardly any effect on the function. 4. ACTH, cortisone, prednisolone, testosterone, progesterone, and pulverized thyroid act directly on megakaryocytes so as to accelerate their function, while estradiol diminishes the megakaryocyte function. 5. For the megakaryocytes in idiopathic thrombocytopenic purpura ACTH is most effective in restoring the function; for the megakaryocytes in hypoplastic anemia cortisone is most effective; and for the megakaryocytes in Banti's disease prednisolone is most effective in restoring the megakaryocyte function.

1. Methods of retrograde coronary perfusion and direct coronary artery perfusion in combination with a bubble oxygenator were investigated in dogs. 2. Ventricular fibrillation occurred more frequently during the operation in hypothermia than in the operation performed in combination with the extracorporeal circulation. 3. The optimal pressure of perfusion is considered to be 30 to 35 mm Hg in retroperfusion, whereas, 100 mm Hg in direct coronary artery perfusion. 4. Perfusion by the pressure bottle method is preferable to the gravity method because the fall of blood temperature in the irrigation tubing might cause ventricular fibrillation. 5. From the metabolic study of the methods is clear that there is a tendency to myocardial anoxia after 15 to 20 minutes of perfusion in both methods.

1. With a view to grasp more simply and clearly the characteristics of this disease and in order to find a clue for prompt discovery of cases when encountered in future, the authors undertook a statistical study of the cases already reported by various authors. 2. The cases reported so far amount to 17 familial groups which consisted of 38 acatalasemic cases. These groups were distributed widely throughout Japan. The disease seemed to be prevalent in the rural communities where adherence to the custom of consanguineous marriage occurs. As yet, we have not heard of the occurrence of this disease in other countries. 3. The disease has equal distribution in both sexes. About one half of patients showed a peculiar oral gangrene (Takahara's disease). The great majority of these were noted in those less than 10 years of age. 4. The great majority of them were children whose parents were united in consanguineous marriage and have siblings with acatalasemia. 5. As for the treatment of oral lesions in this disease, extraction of tooth at the site of the lesions, removal of the diseased tissues en masse by resection, and penicillin treatment given concomitantly are effective. The course and the length of time required in healing of the wound due to the operation are about the same as in the case of normal persons. 6. The authors wish to call special attention to the phenomenon peculiar to the acatalasemic blood. The blood of acatalasemic individuals changes to brownish-black color in the absence of foaming or bubble formation upon the application of hydrogen peroxide to blood.

Using the erythroid cells of Rana nigromaculata the hemoglobin synthesis has been studied in the relation of DNA and RNA contents. Results showed that the hemoglobin synthesis starts in the early stage of erythroblast but becomes marked just before the complete maturation. RNA contents drops markedly in the later stage of maturation. Measurement of DNA contents by Feulgen reaction suggested the termination of the mitosis just before the prematuration. From these results the author concludes that the RNA which will act as the template for the globin synthesis, develops from the early stage of erythroblast but the templation is accelerated in the terminal stage of maturation and the marked acceleration in hemoglobin synthesis in this stage.

The clinical manifestations, roentgenologic studies, and histopathologic findings of the central nervous system of rats with induced lathyrism were described. The question of whether the experimental lathyrism is due to a primary central nervous system involvement or is entirely secondary to bony abnormality is not conclusively answered by this study. However, the evidence of diffuse widespread vacuolization which is more marked in the cord, medulla, and cerebellum than in the hemisphere, strongly suggests the former etiology.

Experiment on the animals proved that in the case of the death by drowning planktons always immigrate into the bone marrow and some kinds of them can be detected in the bone marrow even after a long period of time, suggesting that the detection of these planktons in the bone marrow of the dead person will give the important clue for the determination of the cause of death by drowning. Actually applying this method in a decayed corpse, we could successfully show the cause of death is due to drowning in which the cause of death was long argued in the court.

1. Retrograde coronary perfusion in combination with selective brain cooling by irrigation was investigated in dogs, in comparison with direct coronary artery perfusion. 2. High incidence of ventricular fibrillation was seen in both methods in hypothermic state. Operation at the normal temperature using extracorporeal circulation is desirable, 3. In view of the above results optimal perfusion pressure appears 30 mm Hg. in retroperfusion, while 100 mm Hg. in direct coronary artery perfusion. 4. The right ventricle anoxia is an undesirable feature in retroperfusion, while the left ventricle showed a tendency to slight anoxia in both methods.

1. Effects of various kinds of adequate stimuli such as touching, pinching, heating and cooling to various skin areas as well as repetitive electrical stimulations to a nerve branch innervating the skin areas upon the unitary discharges of the expiratory or the inspiratory muscle units of the intercostal muscles were studied on the spinal dogs. Effects of pinching upon the intercostal nerve action potentials elicited in reflex by single electrical shock to the adjacent intercostal nerve were also studied. 2. Excitatory skin area for the expiratory discharges roughly exhibits a triangle, one of whose vertex faces the sternum, the side against the vertex corresponds to the apical line of the spine and includes the spot from where the discharges of a muscle unit are led off. The triangular area is surrounded by a belt-shaped zone having no reflex response. All the other wide area is the inhibitory one. 3. Both the excitatory and the inhibitory skin areas for the discharges of the inspiratory muscle unit are exceedingly narrow in contrast to those for the expiratory discharge, having a tendency to be limited to the small localized area involving the spot from where the discharges are led off. In the other extensive area, however, any reflex effect is not provoked. 4. The more intense and noxious the adequate stimuli become, the more prominent the effect come to be. 5. When the repetitive electrical stimuli to the skin nerve innervating the excitatory area are weak in intensity or low in frequency, an increasing discharge of the respiratory muscle unit results, whereas when the stimuli are sufficiently raised in either of the two factors above described, a remarkable inhibition preceded by a momentary acceleration ensues. In the case of stimulation of the skin nerve innervating the inhibitory area, however, the inhibition alone is obtained throughout. 6. Reflex action potentials in the intercostal nerve elicited by single shock stimuli to the adjacent intercostal nerve show a shortening of latency and an increase in size by pinching the excitatory skin area, while the reverse effects to those above described are obtained by pinching the inhibitory one.

It is well known that human serum contains some sialic acid and its contents increase markedly in the blood serum of the patients bearing malignant tumors. Recently YAMAKAWA2, BHOM3, SAITO4 and YUI5 observed the sialic acid contents in the blood sera from the patients of various diseases and clarified that its contents increase not only in the sera from the cases bearing malignant tumors but also in those of rheumatic or tuberculous diseases. BOHM6 et al. measured the sialic acid contents in the cerebrospinal fluid of several diseases and ascertained that its contents increase in the cerebrospinal fuid from the cases of inflammatory diseases. In connection with these works we have observed the sialic acid contents in the cerebrospinal fluid of the patients suffering from the diseases of central nervous system, prior to the surgical operation, and revealed the markedly increased contents in the sialic acid in the patients bearing tumors of the nervous system. In this paper the data are reported in detail.

1) The incorporation of DL-Iysine-2-C14 into the protein of the muscle tissues of rats was reduced by thyroidectomy, but that into liver was not significantly affected. 2) The incorporation of radioactive lysine into the proteins of muscle and liver was increased by L-thyroxine administration.
