Heart Conducting System

Benzo[a]pyrene is a polycyclic aromatic hydrocarbon of well proved toxic effect on animal cells and tissues. We used chicken in ovo developmental model to verify its influence on selected parameters of the heart rhythm and on the antioxidative defense in the heart tissue. We determined that the dose of 1 mg/kg weight of eggs of benzo[a]pyrene strongly activates the glutathione-dependent antioxidative system, but it do not significantly affect the heart conducting system of the chicken embryo. We postulate that further study on the benzo[a]pyrene action during embryonic development of birds is recommended.

Systemic Nature

The systemic nature of the disease of sunflower plants caused by Diaporthe helianthi, the leaf–petiole–stem route of the host invasion by the fungus, and the plant tissues that were successively affected were demonstrated through histological studies. After penetration into the host, the infection hyphae invade the intercellular spaces and terminal veinlets of the lamina and spread toward larger branches of the conducting system, the midrib, and the petiole. Xylem elements are invaded but are affected less by the fungus attack than the phloem and the parenchyma tissues, which disintegrate completely. Hyphae spread through the leaf axil to the tissues of the stem cortex, where pycnidia of the Phomopsis anamorph are initiated from internal masses of mycelium. Key words: systemic plant diseases, sunflower diseases, Diaporthe helianthi, Phomopsis helianthi.

Microcirculatory Function

The microcirculation describes the smallest elements of the cardiovascular conducting system and is pivotal in the maintenance of homeostasis. Microcirculatory dysfunction is present early in the pathophysiology of sepsis, with the extent of microcirculatory derangement relating to disease severity and prognosis in ICU patients. However, at present microcirculatory function is not routinely monitored at the bedside. This article describes the pathophysiology of microcirculatory derangements in sepsis, methods of its measurement and evidence to support their clinical use.

Shape And Size

1. Electrical pulses (amplitude -0.05 to -15 mV.; duration 20-120 msec.) have been recorded from the stolon of Cordylophora lacustris following stimulation. These pulses are propagated with an average velocity of 2.7 cm./sec. at 22° C. 2. Brief electric shocks of little more than threshold intensity can evoke bursts of pulses. The number of pulses in a burst increases with stimulus intensity, but the shape and size of individual pulses do not. 3. Repetitive stimulation causes facilitation of both size of single pulses and number of pulses in a burst. Refractory period, if present, is variable. The minimum interval between two pulses is about 200 msec. 4. Mechanical stimulation evokes pulses identical to those evoked by electrical stimulation. 5. The greater the number of pulses recorded in the stolon near a polyp, the greater and faster is the contraction of that polyp. 6. The number of pulses, but not their individual sizes, decreases with increasing distance from the point of stimulation. 7. It is concluded that conduction in the stolon and the electrical pulses are due to nervous activity and that the conducting system is a network having interneural junctions which sometimes require to be facilitated.
