[Diagnostic system for assessment of left ventricular function with 99mTc-albumin (author's transl)].

Diagnostic system is described that obtains a set of serial gated images (SGI) covering the entire cardiac cycles and left ventricular (LV) volume curve (VC) with high temporal resolution (10 msec). The system consists of two functional parts. The one, which is based upon an inexpensive modification of multiformat imaging device, yields SGI. The other, which is based on a minicomputer system, acquires data only from around about LV area and yields LVVC from ECG P wave without the reconstruction of these images. In as little as 5 min result, which is also corrected uniformity of gamma-camera, is given.

Angiography of the iliofemoral arteriovenous system supplying free groin flaps and free hypogastric flaps.

The circulatory anatomy of the iliofemoral region was elucidated by doing detailed angiography in 50 cases, and we classified the vessels into 4 types. In most cases, the s.c.i.a. predominated over the s.i.e.a. Therefore, it is probably better to plan free flaps supplied by this artery. This vessel usually arises approximately two or three fingerbreadths inferior to the intersection of the femoral artery and the inguinal ligament, and the skin flap should be designed in the area inferior and parallel to the inguinal ligament.

Mortality and causes of death in the aged with organic brain symptoms.

By various mental status rating methods, 363 aged residents at a nursing home (aged 80 years on the average) were previously evaluated with regard to chronic brain syndrome (CBS), and now at two and four years thereafter, the relation between mortality and the degree of CBS was statistically tested. The results showed that the severer the CBS, the higher the mortality, with significant difference. In 136 autopsy cases, the primary cause of death was investigated. The results showed no significant difference in the cause of death, either between dementia and non-dementia groups or between groups of mild, moderate and severe CBS.

Metabolic fate of carteolol hydrochloride, (OPC-1085) VIII, a new beta-adrenergic blocking agent. Pharmacokinetic studies of carteolol in man.

The pharmacokinetics of 5-(3-tert.-butylamino-2-hydroxy)-propoxy-3,4-dihydrocarbostyril hydrochloride (carteolol hydrochloride, OPC-1085) have been investigated in man following single or repetitive oral administration. The plasma half-lives. The plasma half-lives of carteolol at single doses of 10, 15 and 30 mg were 5.4, 5.5 and 5.0 h, respectively. The amounts of carteolol excreted into urine within 24 h at the same dose levels accounted for 64, 70 and 76% of the respective doses. The half-lives obtained by the Sigmaminus method were 5.6, 5.6 and 5.4 h, respectively, being essentially consistent with the aforementioned plasma half-lives of carteolol after administration at 15 mg daily for 7 successive days were determined to be 5.54 h on the 1st day and 6.91 h on the 7th day, displaying the increase in half-life value with the repetitive dosing. While, the predicted value determined using the experimental value on the 1st day agreed with the experimental value on the 7th day. Furthermore, the amounts of carteolol excreted in the urine were not significantly different between the 1st and 7th days. The 7-day repetitive administration with carteolol brought about the steady state of plasma levels. It was concluded from these results that carteolol has little ability to accumulate in man.

The inhibition of pulmonary maturation in the fetal rabbit by maternal treatment with phenobarbital.

Phenobarbital was administered to pregnant rabbits, 7 to 10 days before the delivery of their fetuses at 27 to 30 days of gestation. There were no differences in body weight or wet or dry lung weights between control animals and phenobarbital-treated pups at similar gestational ages. The phospholipid content (PLC) of the alevolar wash was lower in the phenobarbital-treated group, but there was no difference in the lung tissue PLC between the treated and control groups. Phenobarbital-treated pups had higher opening pressures and fewer lamellar bodies than the control animals. These data suggest that phenobarbital may have an inhibitory effect on surfactant production and/or release.

Acceleration of fetal lung maturation by aminophyllin in pregnant rabbits.

To test the hypothesis that fetal lung maturation can be accelerated by one of the xanthine derivatives, aminophyllin was given to 40 pregnant rabbits beginning on the 20th gestational day for a period of 7-10 days. The fetuses were delivered by cesarean section and fetal lung maturity was assessed by determining the biochemical, functional, and ultrastructural characteristics of aminophyllin-treated vs. control animals. The phospholipid content of the lung tissue homogenate from the aminophyllin-treated group was significantly higher than in the control subjects (saline injected) at 28 days of gestation (421 +/- 9 vs. 368 +/- 12 mug/mg wet wt, mean +/- SEM) and at 29 days of gestation (531 +/- 10 vs. 475 +/- 20). The alveolar wash phospholipid content of the aminophyllin-treated group was higher at 30 days (167 +/- 9 mug/mg dry wt, mean +/- SEM vs. 117 +/- 17). The lung compliance derived from pressure volume curves was also significantly higher in the aminophyllin-treated group when compared with controls at 27 days of gestation (0.023 +/- 0.0005 ml/cm H2O, mean +/- SEM vs 0.010 +/- 0.0002) and at 28 days of gestation (0.048 +/- 0.0003 vs 0.035 +/- 0.0006). There was no significant difference in the number of lamellar bodies in the type II cells between the aminophyllin-treated and the control groups. The data show that aminophyllin has accelerating effects on fetal lung maturation in rabbits when the drug is given to pregnant rabbits during the last 7-10 days of gestation.
