From the point of view of practical surgery, the most pressing issue here is the fate of the placenta in cases of late-gestational and postpartum ectopic pregnancies. While the removal of the fetus in such cases usually presents no particular difficulties, the surgeon in most cases of late ectopic pregnancy has to consider how to deal with the fetal sac, because removing the latter is often very risky and proves to be very difficult, and sometimes completely technically impossible, such as when the placenta is attached at the root of the mesentery, in the area of large vessels. From this point of view, the following 2 cases of late ectopic pregnancy, observed by us among the total number of 38 cases of ectopic pregnancy admitted to the department from 1920 to 1926, are of a certain interest.

From the point of view of the mechanical theory explaining the occurrence of an ectopic pregnancy by a violation of the transport of the egg cell, the first stage where an ectopic inoculation of an egg can occur will be the inner surface of the follicle itself, in which this egg has matured. The possibility of such an intrafollicular ovarian pregnancy has been proven by the well-known case of C. van Tussenbroeck1) and recently confirmed by the observation of Hoehne2). In such cases, the release of the egg from the follicle cavity does not occur at all.

Introduction. The case report describes a 29-year-old nulliparous woman that was admitted at the Department of Gynecology and Obstetrics of the Clinical Hospital Osijek complaining of mild abdominal pain without vaginal discharge. Case Outline. The patient?s menstrual cycle was irregular, from 30-45 days. An ultrasound examination showed suspicion of an ectopic pregnancy with a ?HCG level of 1358 IU/L. Due to the presence of liquid in the pouch of Douglas the patient underwent emergency laparoscopy, which showed the presence of tumor mass between the right Fallopian tube and the appendix. These two structures associated with adhesions corresponded to secondary implantation after spontaneous tubal abortion which was confirmed by histopathologic analysis. Conclusion. Laparoscopy has emerged as the ?gold standard? in the diagnosis and treatment of ectopic pregnancy, in this case the secondary abdominal pregnancy. From the diagnostic point of view, all women of reproductive age should be considered pregnant until proven otherwise, also keeping in mind that ectopic pregnancies can have different locations and many clinical features.

The technical details of the implantation of tubes into the uterus are given by Volkmann (Zentr. F. G., 1925, no. 33) The most suitable segment of the tube from a functional point of view is its lateral part, which may be quite suitable for transplantation, for example, in cases of an ectopic pregnancy and inflammatory tube changes. During the operation, damage to the vessels must be avoided. Stopping bleeding must be done carefully. Any mechanical damage to the pipe should be avoided by grasping it with tweezers or pulp.

Recently, substantial progress has been made in diagnosis and treatment, complicated ectopic pregnancy is a not negligible cause of maternal mortality, being the leading cause of maternal death in the first trimester of pregnancy and responsible for 6% of maternal deaths. The aim of this study is to evaluate patients with ectopic pregnancy from a clinical, paraclinical and therapeutic point of view and to compare the influence of the management on hospitalization days and the preservation of patients fertility. This paper presents a prospective case-control study for 65 patients, who have been diagnosed serologically and ultrasonically. In the group of patients studied, 25% patients were treated with methotrexate, 65% were required surgical treatment, 4% required surgical and medical treatment, and 2% the management of expectation. Laparoscopy significantly reduces the hospitalization period, contributing decisively to the rapid reintegration into society, increasing patient comfort, an excellent mental tone that promotes earlier healing, the number of complications decreases.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

ABSTRACTThe mechanism by which a shepherd satellite exerts a confining torque on a ring is considered from the point of view of a single ring particle. It is still not clear how one might most meaningfully include damping effects and other collisional processes into this type of approach to the problem.

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

1. Introduction. Studies of radiation damage in ceramics are of interest not only from a fundamental point of view but also because it is important to understand the behavior of ceramics in various practical radiation enyironments- fission and fusion reactors, nuclear waste storage media, ion-implantation devices, outer space, etc. A great deal of work has been done on the spectroscopy of point defects and small defect clusters in ceramics, but relatively little has been performed on defect agglomeration using transmission electron microscopy (TEM) in the same kind of detail that has been so successful in metals. This article will assess our present understanding of radiation damage in ceramics with illustrations using results obtained from the authors' work.

Osmoregulatory mechanisms in algae were investigated mainly from a physiological point of view (KAUSS 1977, HELLEBUST 1976). In Porphyra two osmotic agents, i. e. floridoside/isofloridoside (KAUSS 1968) and certain ions, such as K+ and Na+(EPPLEY et al. 1960) are considered for osmotic balance. Accumulations of ions (particularly Na+) in the cytoplasm during osmotic adaptation is improbable, because the activity of enzymes is generally inhibited by high ionic concentrations (FLOWERS et al. 1977).The cellular organization of Porphyra was studied with special emphasis on the development of the vacuolar system under different hyperosmotic conditions. Porphyra was cultivated at various strengths of the culture medium ASP 12 (PROVASOLI 1961) ranging from normal to 6 times concentrated (6x) culture medium. Por electron microscopy freeze fracturing was used (specimens fixed in 2% glutaraldehyde and incubated in 30% glycerol, preparation in a BALZERS BA 360 M apparatus), because chemical fixation gave poor results.
