| Abstract | We used a navigation system to insert 128 pedicle screws into 69 vertebrae (L1 to L3) of 49 consecutive patients. We assessed the pedicle isthmic width and the permission angle for pedicle screw insertion. The permission angle is the angle defined by the greatest medial and lateral trajectories allowable when placing the screw through the center of the pedicle. The rate of narrow-width pedicles (isthmic width less than 5mm) was 5 of 60 pedicles (8%) at L1, 4 of 60 pedicles (7%) at L2, and none (0%) at L3, L4 and L5. The rate of narrow-angle pedicles (a permission angle less than 15 degrees) was 21 of 60 pedicles (35%) at L1, 7 of 60 (12%) at L2, 3 of 60 (5%) at L3, and none (0%) at L4 and L5. Of 128 pedicle screws inserted into 69 vertebrae from L1 to L3, 125 (97.7%) were classified as Grade 1 (no pedicle perforation). In general, the upper lumbar vertebrae have more narrow-width and -angle pedicles. However, we could reduce the rate of pedicle screw misplacement in upper lumbar vertebra using a three-dimensional fluoroscopy and navigation system. |

| Title Alternative | BALNEOTHERAPEUTIC EXPERIENCES IN GYNECOLOGY (IV) A STATISTICAL INVESTIGATION SPA VISITORS WITH GYNECOLOGICAL DISEASES |
| FullText URL | 012_021_025.pdf |
| Author | Tanaka, Yosinori| |
| Abstract | Investigation on 45 women, taking a cure at Misasa Spa because of various gynecological complaints without advice of doctor, proved that; (1) The vast majority of these women had suffered from their diseases for years, and no medical treatment up to this time could show any favourable effect. (2) Their chief complaints were lower abdominal pain (25%), vaginal discharge (21.9%), lumbago (16%), vaginal bleeding (10.9%), abnormality of menstruation (6.3%), infertility (6.3%), etc.. (3) Pelvic examination in our clinic revealed adnexitis (25%), vaginitis (21.2%), hypoplasia uteri (11.6%), retroflexio uteri (9.6%), infertility (7.7%), etc.. But as the most remarkable fact there were 5 cases (11.6%) of contraindications, (cancer of uterus 2, bleeding myoma of uterus 1, acute phase of adnexitis 2), shown tendency to become worse after thermal baths. (4) In some cases of adnexitis, vaginal discharge, hypoplasia uteri, etc., spa treatment in Misasa proved very effective, and as an "accident thermal" 2 cases of functional bleeding were noted. The author emphasizes that balnetherapy is very useful for various gynecological diseases, but should be supervised and controled by doctor as in Western countries. |

| Abstract | (2) Effects of Thermal Bath on the Sexual Circle of Rat The anthor investigated the sexual circles of rats by the vaginal smear method. Most of the rats who had been taking thermal bath once daily for about 1 month (Misasa Hot Spring, 42°C, 5 minutes) changed their own circles under influence of bath. Detlil is as follows. 1. Of 18 rats shown regular circles before bath, 11 rats (61.2 per cent) maintained their regularity, 7 rats (38.8 per cent) received transient irregularization by bath. 2. Of 67 rats shown irregular sexual circles before bath, 37 rats (55.2 per cent) gained regularity, 18 rats (26.9 per cent) aggravated their irregularity, 12 rats (17.9 per cent) remained unchanged by thermal bath. Therfore 62 of 85 rats changed their sexual circles under influence of thermal bath, and regularization of circle was most remarkable phenomenon. (3) Inquiry into the Mode of the Action. The rats took thermal bath once daily for about 1 month (Misasa Hot Spring, 42°C, 5 minutes), then were used for following various experiments. Results are follows. 1. The thermal bath had no effect on increase of uterus weight due to estrogen injektion. 2. The thermal bath had no effect on increase of ovary weight due to gonadotropin injektion. 3. Formation of corpora lutea in ovary due to estrogen injektion was promoted by thermal bath. This results mean promotion of midbrain-pituitary system, function, because the formation of corpora lutea is considered as a results of stimulation of this system by estrogen. 4. Formtion of castration cells in the anterior lobe of pituitary after operative castration was promoted by thermal bath. 5. Histological picture of the rat's anterior lobe, whose sexual circles had become irregular as a result of thermal bath, showed a slight hyppofunction. 6. Thermal bath accelerated the inactivation of estrogen in the liver of rat in vivo. 7. Radon in thermal warter seems to play no important role in the above mentioned actions of thermal bath. These serial experiments suggest that the midbrain-pituitary system plays especially big part in irre- or regularization of sexual circles by thermal bath. (4) The Effects of Thermal Bath upon the Motility of the Living Rabbit's Fallopian Tube and Uterus. The author proved by means of kymographion and abdominal-window method that the living rabbit's fallopian tube and uterus increased amplitude and frequency of their movement during and after thermal bath (42°C, 5 minutes). |

| Abstract | In frühen Arbeiten habe ich den Nachweiss erbracht, dass Thermalbädern den Brunstzyklus der weiblichen Ratten regelmässig werden lassen, und diese Erscheinung auf die Steigerung der Hupophysenvorderlappenfunktion zurückzuführen ist. Andererseits ist es bekannt, dass Zunahme der acetylcholinartigen Substanz der Zwischenhirn die Steigerung der Hypophysenvorderlappenfunktion mit sich bringt. Unter diesen Gesichtspunkten wurden die Bestimmnngen der acetylcholinartigen Substanz in zwischenhirn der Ratte nach Thermalbade vorgennommen. 47 männliche Ratte wurden in Misasa Therma - radioaktive Thermen - 10 Minuten lang bei 42°C gebadet, dann in 4 Gruppen geteilt, und εfort, an 30., 60., und 90. Minute nach dem Bade wurde diese Subfotanz nach Methode von M. rectus abdeminis der Frosch bestimmt, und mit kontrolltiere verglichen. Es wurde festgestellt, dass freie acetylcholinartige Snbstanz sich an 30. Minute nach dem Bade vermehrte, aber an anderen Zeiten kein statistisch signifikanter Unterschied zwischen Badgruppe lmd Kontrollgruppre hinisichtlich des Gehalt der freien, kombinierten und gesamten acetylcholinartigen Subtanz war. Die Tatsachen lassen daran denken, dass Zunahme der freien acetylcholinartigen Substanz in Zwischenhirn, die gescbah nach dem Thermalbade, sich an Verbesserung der Sexualfunktion von Thermalbädern vielleicht beteiligt. Üher diese Erscheinungen werden die Rolle der Radiumemanation im Thermalwasser und Unterschied zwischen Thermalwasser und Süsswasser in künftigen Arbeiten untersucht werden. |

| Abstract | Konsche Siberreaktion (Kon : Silberreaktion der Zellen - Gustav Fischer) ist eine histochemische methode für den Nachweis der Reduktionskraft der Zellen, die von Professor Kon erfunden wurde und im Zusammenhang mit Vitalität der Zellen besonders der endokrinen Organe steht. Also bedeutet die starke Offenbarung dieser Reaktion die gesteigerte Funktion der Gewebe. Um zu forschen ob die geschlechtsfunktion durch Thermalbad beeinflusst wurde, wurde diese Reaktion auf die Hypophysenvorderlappen, Ovarium und Nebenniere der Ratte nach Thermalbad (schwach radioaktive Therme und H2S Therme, 42°C, 5 Minuten lang) angewandt. Sofort nach einmaligem Bad handelte es sich kein Unterschied zwischen Badgruppe und Komtrollgruppe. Nach eimal täglich 50 tägigen Btidern verstaerkte sich die Reaktion von Hypophysenvorderlappen und Corpus luteum von Ovarium (besonders bei H(2)S Therme) aber in anderer Gewebe befand keine Veraenderung sich. Also ist es klar, dass Funktion von Hypophysenvorderlappen und Ovarium nach wiederholten Thermalbaedern sich steigert. |

| Title Alternative | o-PHENANTHROLINE METHOD APPLIED TO THE DETERMINATION OF IRON IN NATURAL WATERS |
| FullText URL | pitsr_017_001_007.pdf |
| Author | Tanaka, Shigeo| |
| Abstract | The o-phenanthroline method was tested as to its applicability to the separate determination of iron in natural water: ionic ferrous iron, reducible iron, snd colloidally dispersed iron. In connection with this, the results of the following experiments are given in this paper. 1. Determination of the absorption curve of o-phenanthroline ferrous complex. (Figure 1.) 2. Construction of the calibration curve for a Purfrich's photometer with filter S 50, 15 cm cuvettes. (Figure 2.) 3. Examination of the effects of coexisting anions on the determination of iron by the method of three way layout. (Table 1., Table 2.) 4. Trial determinations of iron in three different states in solution. (Table 3., Table 4. ) 5. Test of the applicability of this method to the determination of ionic ferrous iron and reducible iron in thermal water. (Table 5., Table 6.) From the above, it was revealed that ionic ferrous iron and reducible iron in natural water are separately determinable with sufficient accuracy by the o-phenanthroline method, and that ionic iron and colloidally dispersed iron are also separately determinable, when the dispersed iron is present in amount more than 1.3% of the total iron. |

| Title Alternative | THE CHANGE IN CONCENTRATION OF FERROUS IRON AND REDUCIBLE IRON, DISSOLVED IN SPRING WATER AT MISASA HOT SPRINGS, JAPAN, DURING PRESERVATION OF THE WATER SAMPLE IN A SEALED BOTTLE |
| FullText URL | pitsr_020_048_054.pdf |
| Author | Tanaka, Shigeo| |
| Abstract | The two sprigns called "Tanaka-no-Yu" and "Hisui-no-Yu" at Misasa Hot Springs, japan (Fig. 1), suitable for sampling the unpolluted water, the locations of which, are shown in Fig. 2, were chosen for this study. The o-phenanthroline method, details of which were discussed in the previous report by the author (Repts. Balneol. Lab. Okyama Univ., 17, 1, (1956)) was used for the determination of ferrous iron, ferrous iron + reducible iron, and ferrous iron + reducible iron + colloidally dispersed iron (to be referred to as "total irons" in this report). For comparison, the change in concentratin of iron dissolved in distilled water during preservation in a sealed bottle was observed, and the results obtained for the solutions with the pH values of 5.4 and 5.8 are illustrated in Fig.3 and Fig.5, rspectively. Both ferrous and reducible iron disappear within 5 minutes, when the pH of the solution is 6.4. The hydrogen ion concentration was thus seen to give a sensitive effects on the speed of diminution of ferrous and reducible iron dissolved in the distilled water. It should be noticed that no appreciable diminution was observed during the period from 60 min. to 120 min,. It is probable that the diminution of total iron is caused by the adsorption of colloidal iron hydroxides on the wall of glass bottle. The effects of charged anion (SO(4)(--)) on the change in concentration of iron during preservation was also investigated, but no appreciable effect was found. (Fig. 5 and Fig. 6). Fig.7, Fig.8, and Fig.9 show the change in concentration of iron during preservation of the spring water at "Tanaka-no-Yu". The content of iron in the spring water is about 0.3 mg/l, and its pH value is about 7.1. For the first 30 minutes, ferrous iron diminishes rapidly, the slope of the diminution curve being sharp and almost straight. Thereafter the slope becomes gentler, and, after an hour, the slope approaches nearly zero. On the other hand, ferrous iron dissolved in distilled water disappears in a moment at the same pH 7.1. Fig.10, Fig.11, and Fig.12 show the change in concentration of iron during preservation of the spring water at "Hisui-no-Yu". The content of iron in the spring water is about 1.0 mg/l, and its pH value is about 6.4. In this case, the diminution of ferrous iron is not remarkable, and only 20% of the initial quantity diminishes within 2 days. Whereas, in the case of distilled water, the diminution is very rapid at the same pH 6,4, and the ferrous iron disappears completely within 5 minutes. In Fig.13 the speed of diminution of iron in distilled water and that in spring water are compared. The difference here seen may probably be due either to that the ferrous iron in spring water is in a certain complex form not easily oxidizable, or to that the spring water contains some reducing substances. |

| Abstract | Differential thermal investigation was made of amorphous hydrous ferric oxides, precipitated on neutralization of ferric chloride solution under different laboratory conditions, ranging from DOC to 85°C in temperature, and from 3 to 12 in pH. Each of the differential thermal curves obtained shows an endothermic peak due to the release of adsorbed water, followed by a exothermic peak due to crystallization of anhydrous ferric oxide to hematite. The temperature corresponding to the exothermic peak varies in the range from 240°C to 460°C accrding to the temperatures and pH values of the solution from which the hydrous ferric oxide is precipitated. |

| Title Alternative | Study of Togo -Matsuzaki Hot Springs, Tottori Prefecture |
| FullText URL | pitsr_023_001_022.pdf |

| Abstract | 1. Layers containing thermal water in this district are thin, and lie at different depths (about 35, 55, and 60 meters) from the ground surface. There are evidences to show that these layers are intimately connected with one another. 2. The authors may suppose the existence of a structurally weak zone, along the line from Matsuzaki to Asozu, within which the issuing spots of thermal springs are located. 3. The head water levels of the thermal springs in this district are closely related with that of Lake Togo. Keeping pace with the variations of the water levels of Lake Togo and of artesian wells in its vicinity, the rate of flow of thermal springs vary; and the correlation between these variations is apparent. 4. The pumping suction of thermal water at one spring affects the flow of water at other springs within distances of 150 to 200 meters therefrom, though the direct sources of thermal water supply for the latter springs may be different from that of the former. 5. The spring water in this district is considered to be a mixture of hot water, containing sodium, calcium, chloride, and sulfate ions, and cold water, containing bicarbonate ion. The diversity of chemical constitutions of different spring waters is explained as due to the difference in proportion in which the hot and cold waters are mixed. |

| Title Alternative | Isotopic study of Hot Springs in Japan, I Techniques for oxygen isotopic analysis of spring water |
| FullText URL | pitsr_040_033_040.pdf |

| Abstract | The CO(2)-H(2)O isotopic equilibration technique was studied for the routine analyses of the oxygen isotopic ratios of hot spring water. A reaction vessel containing 2 ml of water and 0.16 m mole of tank CO(2) was shaken for 18 hrs. in a constant-temperature bath at 25.0℃ (Figs. 1, 2, and 3), and the CO(2) was analyzed for the oxygen isotopic ratio by a MCKINNEY type mass spectrometer. Several aliquots of 1, 2 and 5 ml from a same water were each analyzed three times by successive equilibration (Table 1). The observed values differ depending on the volume of water but the corrected values by equation (6) indicate excellent agreement, implying the whole processes to be well controlled. The reproducibility of the isotopic analyses is better than ± 0.1‰ (Table 2) in most cases, and the accuracy would not be worse than ± 0.2‰ as demonstrated by the interlaboratory comparison of some standard samples (Table 3). Oxygen isotopic ratios of water from more than 70 hot springs in Japan are presented (Table 5). Although the results will be discussed in the following issues of this series of paper, most hot spring water have the δ(18)O values similar to those of meteoric waters in Japan. However, spring water from Arima Hot Springs, Hyogo-Pref., which has been known by its abnormally high chloride and low sulfate concentrations is of an exceptionally high δ(18)O value. |

| Abstract | Correct screw placement is especially difficult in the upper thoracic vertebrae. At the cervicothoracic junction (C7-T2), problems can arise because of the narrowness of the pedicle and the difficulty of using a lateral image intensifier there. Other upper thoracic vertebrae (T3-6) pose a problem for screw insertion also because of the narrower pedicle. We inserted 154 pedicle screws into 78 vertebrae (C7 to T6) in 38 patients. Screws were placed using intraoperative data acquisition by an isocentric C-arm fluoroscope (Siremobile Iso-C3D) and computer navigation. Out of 90 pedicle screws inserted into 45 vertebrae between C7 and T2, 87 of the 90 (96.7%) screws were classified as grade 1 (no perforation). Of 64 pedicle screws inserted into 33 vertebrae between T3 and T6, 61 of 64 (95.3%) screws were classified as grade 1. In this study, we reduced pedicle screw misplacement at the level of the C7 and upper thoracic (T1-6) vertebrae using the three-dimensional fluoroscopy navigation system. |
