[Prosthetic stomatologic care of citizens 60 years and older in the Stralsund-Land district, based on a representative sample in 1979]. / Zu Problemen der prothetisch-stomatologischen Versorgung bei über 60 Jahre alten Bürgern des Kreises Stralsund-Land, untersucht an Hand einer repräsentativen Stichprobe im Jahre 1979.

The authors report on the state of oral health, dental knowledge and behaviour and prosthodontic care in 304 people. Based on these results the prosthodontic care need in all more than 60 years old inhabitants of Stralsund/Land is estimated.

[Comparison between ketamine, propanidid, and etomidate in general anaesthesia for caesarean section (author's transl)]. / Die Ketaminnarkoseeinleitung bei Sectio caesarea im Vergleich zur Propanidid- oder Etomidateeinleitung.

Propanidid, etomidate, and ketamine were compared for their effects on maternal acid-base balance and circulation as well as on postnatal general condition and acid-base balance of the newborn, on the basis of 44 women in advanced pregnancy to whom caesarean section was applied in general anaesthesia. The probands had not been deliberately selected beforehand. Results obtained from the three above anaesthetics were compared with one another as well as with parameters recorded from spontaneously delivered newborns without any medication. One of the anaesthetics produced sufficiently deep anaesthesia in all patients, and no signs of central depression were recordable from the newborns. The parameters of acid-base balance, following propanidid and etomidate anaesthesia, revealed respiratory acidosis in the newborns immediately after delivery by caesarean section. Their pH values were lower than those recorded in the context of ketamine anaesthesia or spontaneous delivery without any medication. Both values returned to normal within 30 minutes from delivery. The one-minute and five-minute Apgar scores were below those of spontaneous deliveries, at the beginning, but eventually reached normal levels. All the three anaesthetics were found to be suitable for introduction of general anaesthesia for caesarean section on account of high-rate enzymatic degradation and, consequently, absence of foetal depression. Resulting oxygen supply is higher, as compared to spontaneous delivery. Early indication and short-time introduction and delivery, thus possible, have often proved to be important to the newborn's condition.

[Comparative experimental animal studies of the effects of various nuclear pharmaceuticals on the EEG]. / Vergleichende tierexperimentelle Untersuchungen zur Wirkung verschiedener Nuklearpharmaka auf das EEG.

Some of the radiopharmaceuticals presently recommended for cisternoscintigraphy were compared, in experiments on animals, for their effects upon bioelectric activity. On relaxed cats, electroencephalography did not show any effects upon bioelectric activity for 198 Au and 169 Yb Ca DTPA. One test animal each of seven and six cats examined using 169 Yb DTPA and 131 J HSA showed changes in the electroencephalogram subsequent to suboccipital application.
