[The study of regional cerebral blood flow in psychiatric disorders]. / Badania regionalnych przeplywów mózgowych (rCBF) w chorobach psychicznych.

Regional cerebral blood flow is a radiological technique which is safe, non-invasive and relatively cheap. This method allows to assess changes in brain metabolism in patients with psychiatric pathology. The specific changes have been found in regional cerebral blood flow in patients with schizophrenia, affective disorder, obsessive-compulsive disorder as well as alcohol withdrawal and dependence. Advantages and disadvantages of this technique are discussed.

[Assessment of liver pathology on the basis of biochemical and ultrasonographic findings in a group of alcohol dependent patients]. / Ocena patologii watroby u osób uzaleznionych od alkoholu na podstawie badan biochemicznych i metod ultrasonograficznych.

The paper presents the assessment of liver pathology based on clinical examinations, biochemical findings and abdominal ultrasound examination with colour Doppler modalities in a group of 40 alcohol dependent patients. Special regard was paid to the liver, it is size, echogenecity, homogeneity and flow patterns in the portal vein. No significant correlations between the biochemical and USG parameters of liver pathology and the intensity of alcohol withdrawal and the level of the alcohol dependence syndrome were found. It can be concluded that the biochemical parameters as well as ultra sound diagnosis of alcoholic liver disease do not allow to make a final diagnosis of liver pathology.

Behavior of captive mouse deer, Tragulus napu.

1. The behavior of a breeding colony of larger Malayan mouse deer was observed for seven months. 2. Mouse deer produce a noise by stamping with one or both hind feet when slightly alarmed. Other individuals may or may not stamp in response. 3. Both males and females mark objects with the inter-mandibular gland. Males mark much more frequently than females. 4. Males often lick the urine of females; less frequently, females lick the urine of males. Mouse deer do not "flehmen" in response to urine. 5. Males court both receptive and unreceptive females. Courting males mark the female on the back or rump with the inter-mandibular gland and emit a series of squeaks. The behavior of both unreceptive and receptive females and copulation are described. 6. Females have a post-partum estrus and return to estrus at approximately 14 day intervals unless they become pregnant. 7. Mothers spend little time with infants. Mothers emit a vocalization which sounds like the squeak of courting males. Both mothers and infants emit a higher pitched vocalization. If her infant emitted this vocalization the mother answered and approached and stood by it. The mother nurses in a standing position and raises the hind leg on the side towards the infant. 8. Intense agonistic behavior was seen only when strange individuals were introduced into established groups. Males fight by facing each other and biting each other on the ears, neck, and shoulders with their large upper canines. Fighting males usually hold the tail in a vertical position, exposing the white ventral surface, and may emit loud growls. If one male flees, the other pursues and attempts to bite him on the neck and body. 9. Mouse deer are morphologically primitive and many of their motor patterns are also thought to be primitive. 10. The behavior of all four living tragulid species appears to be quite similar, both with respect to motor patterns and social behavior.
