The ammonium content in the tissues of selected species of squid (Cephalopoda: Teuthoidea)

The ammonium ion (NH₄⁺) content in the mantles, fins, arms, haemolymph, and buoyancy fluid of 17 species of squids belonging to nine families was determined. Great individual variation of ammonium concentration was found in the buoyancy fluid of Liocranchia reinhardti(Steenstrup, 1856), i.e. 38–1108 mM, and in the vacuolized tissues of Histioteuthis macrohista N. Voss, 1969, i.e. 50–775 mM.     

Diagnosis of cerebello-pontine angle tumors

History and results of investigations in 34 patients with cerebello-pontine angle tumours are presented. Tumour was diagnosed in the first, audiological stage of the disease only in 4 patients. In 7 more patients additional symptoms of central nervous system focal disorders occurred. The remaining 23 patients were in the third stage of the disease with symptoms of increased intracranial pressure. The main reason for such a late diagnosis of the tumour was neglecting of the early audiological symptoms of the disease by patients and by general practitioners as well.     

Favism in Polish families

Four cases of fawism are presented. The disease was seen in one male patient, one homozygote and in 3 carriers of G6PD deficit. Diagnostic procedures, course of the haemolytic crisis in these patients, and possibility of prophylaxis in the families with fawism are discussed.
