The body, of which the dissection is described in this paper, exhibited a considerable tumour, placed immediately above the region of the pubis. Upon opening the abdomen, a quantity of fluid resembling blood was found in its cavity, and a tumour, four times the size of a hen’s egg, obstructed the view of the internal parts of generation, resting upon the left portion of the anterior surface of the uterus; a blood-vessel, which proved to be a branch of the left spermatic artery, and of the size of a large crow-quill, penetrated the dense portion of this tumour, and a smaller vessel communicated with the spermatic vein. The inferior portion of the tumour presented diaphanous membranes, through which was seen a fœtus of about four months’ growth. The fact of an extra-uterine conception being thus made out, the author proceeded to examine the connection of the tumour with the neighbouring parts, and the condition of the uterus; whence it appears that the tumour was seated in the left ovarium, which had burst in three places, so as to suffer the membranous sac containing the fœtus to protrude into the cavity of the abdomen; and that by the growth of the fœtus that part of the covering of the ovarium was ultimately lacerated, which involved the placenta by which the adhesions of the latter were torn, producing the sudden and fatal hæmorrhage which killed the patient and filled the abdomen with blood.

Pericytes are vascular satellites present around capillary blood vessels and small venules. They have been observed in almost every tissue of the body and are thought to be related to vascular smooth muscle cells. Morphologically pericytes have great similarity to vascular endothelial cells and also slightly resemble myoepithelial cells.The present study describes the ultrastructural morphology of pericytes in normal breast tissue and in benign tumor of the breast. The study showed that pericytes are ovoid or elongated cells separated from the endothelial cell of the capillary blood vessel by the basement membrane of endothelial cell. The nuclei of pericytes are often very distinctive. Although some are round, oval, or elongated, others show marked irregularity and infolding of the nuclear membrane. The cytoplasm shows mono-or bipolar extension in which the cytoplasmic organelles are located (Fig. 1). These cytoplasmic extensions embrace the capillary blood vessel incompletely. The plasma membrane exhibits multiple areas of focal condensation called hemidesmosomes (Fig. 2, arrow). A variable number of pinocytotic vesicles are frequently seen lining the outer plasma membrane. Normally pericytes are surrounded by a basement membrane which is found more consistently on the outer plasma membrane separating the pericytes from the stromal connective tissue.

Blood Flows

Blood pressure is the force of blood pushing against blood vessel walls as the heart pumps out blood, and high blood pressure, also called hypertension, is an increase in the amount of force that blood places on blood vessels as it moves through the body. Factors that can increase this force include higher blood volume due to extra fluid in the blood and blood vessels that are narrow, stiff, or clogged(1). High blood pressure can damage blood vessels in the kidneys, reducing their ability to work properly. When the force of blood flow is high, blood vessels stretch so blood flows more easily. Eventually, this stretching scars and weakens blood vessels throughout the body, including those in the kidneys.

1. The body composition was determined of forty-one fetuses of different gestational ages born to mothers belonging to a low socio-economic group of the population.2. With increasing gestational age the water content fell from 88% at 28 weeks to 76% at term; the fat content increased from 2.1% to 11.2% and the protein content increased from 6.9 to 9.3%.3. The changes in body composition were more closely related to body-weight than to gestational age.4. The calcium, Phosphorus and magnesium contents of the body per unit fat-free weight progressively increased with gestational age, and at term the values appeared to be considerably lower than those reported in the literature. The Ca:P ratio was constant at different body-weights.5. The body iron content per unit of fat-free weight increased marginally with increasing gestational age. The value was almost 30% lower than the values reported from elsewhere.6. It is suggested that chemical composition and nutrient stores of the developing foetus can be considerably influenced by the state of maternal nutrition.

Life Threatening

The abdominal cavity is, in essence, an appendage of the lymphatic system, therefore, it cannot represent a completely foreign container for the blood poured out here. Indeed, the observations of Virchow, Wintrich and others show that whole blood can remain in this cavity for a long time (several days) without undergoing clotting (Pashutin). In view of this fact, it is natural to expect, as is confirmed by experiments, that most of the blood that has entered the abdominal cavity has time to be absorbed before it begins to coagulate. If a part of it, which failed to be absorbed in time, undergoes clotting, then this does not represent any particular disturbances in the overall economy of blood, the blood clot is completely absorbed after preliminary disintegration (fat). In this sense, hemorrhage into the abdominal cavity is not life-threatening, since the blood does not disappear for the body, but soon again, almost entirely, enters the total mass of the blood vessel.

Vasculitis is an inflammation of the blood vessels. It can affect any blood vessel in the body by manifesting a variety of systemic, non-specific symptoms that make difficult the diagnosis of this pathology and especially its specific form. In front of any patient suspected of being affected by vasculitis, some questions are asked: Is the vasculitis or other pathology that camouflages, whether it is primary or secondary vasculitis, in which vessels this pathology extends, how can the diagnosis be confirmed and how can it be determined the type of vasculitis?The purpose of this study is to inform about the protocols to be followed to perform differential diagnosis of vasculitis types.This study is a review based on the research of world studies and literature regarding the recommendations for performing differential diagnosis among the variety of vasculitis forms.Primary patient assessment involves taking the history of the medications it uses, risk factors for infectious pathology, history of cardiac valve pathologies, and autoimmune pathologies. Then laboratory and imaging studies are carried out, aiming at setting the diagnosis, determining the affected organ and the degree of disease activity. And recently we refer to algorithms to make differential diagnosis between the varieties of vasculitis forms.Despite the diagnostic difficulties of vasculitis, the variety of its forms, the separation of responsibilities among many specialities, there are protocols that need to be followed rigorously to arrive at a safe diagnosis as well as auxiliary algorithms to distinguish the type of vasculitis.

Abstract In this study a theoretical model was developed to evaluate the temperature difference between the body core and the arterial blood supplied to the brain. Several factors including the local blood perfusion rate, blood vessel bifurcation in the neck, and blood vessel pairs on both sides of the neck were considered in the model. The theoretical approach was used to estimate the potential for cooling of blood in the carotid artery on its way to the brain by heat exchange with its countercurrent jugular vein and by the radial heat conduction loss to the cool neck surface. It shows that blood temperature along the common and internal carotid arteries typically decreases up to 0.86°C during hyperthermia. Selectively cooling the neck surface during hypothermia increases the heat loss from the carotid arteries and results in approximately 1.2°C in the carotid arterial temperature. This research could provide indirect evidence of the existence of selective brain cooling (SBC) in humans during hyperthermia. The simulated results can also be used to evaluate the feasibility of lowering brain temperature effectively by selectively cooling the head and neck surface during hypothermia treatment for brain injury or multiple sclerosis.

AbstractThe sound environment of the foetal lamb was recorded using a hydrophone implanted a few weeks before term in a small number of pregnant ewes. It was implanted inside the amniotic sac and sutured loosely to the foetal neck, to move with the foetus. Results differ from those reported earlier for the human foetus: sounds from the maternal cardiovascular system were picked up only rarely, at very low frequencies and at sound pressures around, or below, the human auditory threshold. Other sounds from within the mother occurred intermittently and rose to a high sound pressure only at frequencies above about 300 Hz. Sounds from outside the mother were picked up by the implanted hydrophone when the external sound level rose above 65-70 dB SPL, and the attenuation in sound pressure was rarely more than 30 dB and, especially at low frequencies, usually much less. However, attenuation due to the transmission of sound through the body wall and other tissues tended to change from time to time. It is concluded that the foetal lamb's sound environment consists of (1) intermittent low frequency sounds associated largely with the ewe's feeding and digestive processes and (2) sounds such as vocalisations from the flock, human voices and other sounds from outside the mother.

Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Children affected by the Marfan syndrome carry a mutation in one of their two copies of the gene that encodes the connective tissue protein fibrillin-1. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessel that distributes blood from the heart to the rest of the body. A case report of Marfan syndrome has been reported with oral features. The dental problems of the child were treated under general anesthesia and a one-month review showed intact stainless steel crowns' restorations and no signs of secondary caries.
