Partial tetrasomy 9(9pter to 9q2101) due to an extra iso-dicentric chromosome.

A 3-year-old boy with partial No. 9 tetrasomy is described. The patient showed markedly retarded physical and mental development as well as multiple congenital anomalies. Routine chromosome analysis revealed an extra C-group chromosome. It had a pronounced secondary constriction at the proximal part of its long arm. Based on studies by a variety of banding techniques, the extra chromosome was identified to be an iso-dicentric No. 9 chromosome with inactivation of one of the two centromeres, the karyotype being 47,XY, + DIC (9)(Q2101). The value of BrdUrd treatment was emphasized in the detection of a very small piece of euchromatin within a long stretch of constitutive heterochromatin.

Hyperthermic effects of D-lysergic acid diethylamide (LSD) and its derivatives in rabbits and rats.

Several D-lysergic acid diethylamide (LSD) derivatives including metabolites of LSD in animals liver and Streptomyces such as D-lysergic acid ethyl, 2-hydroxyethylamide (LEO), D-lysergic acid ethylamide (LAE), D-norlysergic acid diethylamide (norLSD) and synthetic N6-allyl-D-norlysergic acid diethylamide (allyl-nor LSD) were studied with rabbits and rats. In rabbits, the order of the hyperthermic activities was allyl-norLSD greater than LSD greater than LEO, LAE, nor-LSD, and this order was parallel to that of 5-hydroxytryptamine-like activities of these compounds which was previously studied. However, the order was LAE greater than LSD greater than norLSD IN RATS. The hyperthermic effect of LSD in rabbits was attenuated by methysergide, but not by atropine when these drugs were intraventricularly administered. These results suggest the possibility that the metabolites of LSD contribute to the hyperthermic effect of LSD in rats but not in rabbits, and support the idea that 5-HT receptors are involved in the hyperthermia induced by LSD in rabbits.

Effect of total gastrectomy on acid proteolytic zymogens in serum and urine.

Proteolytic pH-activity curve and agar gel electrophoretic pattern of acid proteolytic zymogens in serum and urine were studied in totally gastrectomized patients. In serum, total gastrectomy was found to reduce proteolytic activity markedly, but no appreciable changes could be detected by electrophoretic analysis. In urine, however, in addition to the marked reduction of proteolytic activity, changes were found in electrophoretic pattern after total gastrectomy. Namely, fraction Pg 3 tended to persist, while Pg 5 disappeared along with the lapse of time after total gastrectomy. An unusual appearance of fraction Pg 7 in urine was also observed on the occasion of postoperative transient albuminuria. Their orgins and related clinical problems were discussed.
