[EEG power and coherence in presenile and senile depression. Characteristic findings related to differences between anxiety type and retardation type].
Quantitative EEG analysis was done on 29 medicated right-handed depressive patients at age over 45 and age and sex matched right-handed 20 normal controls. The patients were all diagnosed as major depression with melancholia by DSM-III-R and were divided into anxiety type (n = 17) and retardation type (n = 12) evaluated with the Hamilton rating scale for depression. Eye closed resting EEGs were recorded on a data recorder from the 16 electrode leads (10-20 system). ⋯ In particular, the anxiety type showed significantly lower alpha 2 band and lower beta 1 and beta 2 bands. The parietal interhemispheric coherence was lower in the anxiety type but higher in the retardation type than in normal controls in each band, and this difference was prominent in theta 2 band. 4) The two groups of patients showed higher fronto-parietal intrahemispheric coherences in both hemispheres than the normal controls in each band. Especially, the anxiety type showed higher in theta two and alpha 1 bands.(ABSTRACT TRUNCATED AT 400 WORDS)

Comparative Study[Experimental study of right ventricular assists for severe right ventricular failure].
The efficacy of two right ventricular assist systems for severe right ventricular failure caused by multiple ligation of the right coronary artery and right ventricular free wall with ventricular septal infarction was studied in 20 adult dogs in order to determine a better assist system in terms of hemodynamics and ventricular function. Two types of assist systems, a right ventricular bypass (RVAS) and an RVAS with intraaortic balloon pumping (IABP) were applied. The assist flow changed the preoperative aortic blood flow by 20%, 40%, 60% and 80%, respectively. ⋯ But RVAS did not effectively improve the aortic pressure (AP), left atrial pressure (LAP), aortic flow (AF), coronary sinus flow (CSF), left ventricular end diastolic pressure (LVEDP), LV stroke work (LVSW), or the endocardial viability ratio (EVR). On the other hand, RVAS with IABP significantly improves AP, LAP, AF, CSF, LVEDP, LVSW, and EVR as compared with the data of RVAS only. The optimal assist flow during RVAS with IABP might be 40-60% of the preoperative aortic blood flow.

Case ReportsEnterovesical fistula caused by inflammatory bowel diseases.
Enterovesical fistula caused by inflammatory bowel diseases is a rare disorder. Two male patients with recurrent cystitis had sigmoid colon diverticulitis causing enterovesical fistula. ⋯ The precise diagnosis of enterovesical fistula was made either by cystography or cystoscopy. One-stage resection of the inflamed bowel with fistula and affected the bladder wall was proved to be an effective treatment for these three patients, while a long term follow up is specifically necessary in the patient with Crohn's disease.

[Innervation of the sacroiliac joint. Macroscopical and histological studies].
Macroscopical and histological studies were carried out to clarify nerve innervation of the sacroiliac joint which is believed to have a role in the development of low back pain. Eighteen Japanese adult cadavers were used for gross anatomical examination and six for histological examination of the nerve supply to the joint. The results were as follows: 1) It is suggested by the gross examination that the upper ventral portion of the joint is mainly innervated by the ventral ramus of the 5th lumber nerve. 2) The lower ventral portion of the joint was mainly supplied by the ramus of the 2nd sacral nerve or branches from the sacral plexus. 3) Lateral branches of the dorsal ramus of the 5th lumber nerve were considered to be the main nerves which innervated the upper dorsal portion of the joint. 4) The lower dorsal portion was innervated by nerves arising from a plexus composed of lateral branches of the dorsal rami of the sacral nerves. 5) The nerves which innervate the joint range in diameter from 0.292 mm to 0.997 mm, and no difference was found among those in the four subdivisions of the joint. 6) Histological examination revealed that nerve fibers and the terminals were present in the joint capsule and adjoining ligaments. The nerve fibers varied from 0.2 micron to 2.5 microns in diameter and ended with five morphologically different terminals.
