A case of manic state in which lactation occurred after Li2CO3 administration.

Li2CO3 alone was administered to a 21-year-old female, who was in a manic state. As a consequence, lactation occurred on about the 50th day after Li2CO3 administration started, and the volume of lactation changed in parallel with the serum Li2CO3 level. The basal plasma PRL concentration and the responses to TRH (500 micrograms) were elevated during Li2CO3 administration. However, both of them returned to within the normal range after the suspension of Li2CO3 administration. From the above-mentioned findings, it is suggested that lactation is closely related to the Li2CO3 administration.

Effect of methyl substitution on microbial degradation of linear styrene dimers by two soil bacteria.

The microbial degradation of 10 linear unsaturated dimers (I to IV) prepared from styrene and o-, m-, or p-methylstyrene was investigated with two soil bacteria, Alcaligenes sp. strain 559 and Pseudomonas sp. strain 419. The two strains decomposed styrene dimer I and all styrene-methylstyrene codimers II and III, but methylstyrene homodimers IV remained intact. The degradation rates of codimers II and III of o- and m-methylstyrenes were found to depend on both their structure and the strain used; i.e., Alcaligenes sp. strain 559 decomposed III faster than II, whereas the reverse order (II > III) was obtained with Pseudomonas sp. strain 419. In biodegradation by the former strain, the codimers were degraded faster in the presence of styrene dimer I than in its absence, but no such effect of dimer I was observed with the latter.

The effect of electrical stimulation of the hypothalamus and other brain areas on urea cycle enzymatic activities in the liver in rabbits--experimental studies on brain and liver interrelationship--.

Changes in urea cycle enzymatic activities in the liver induced by intracerebral electrical stimulation in rabbits with chronically implanted electrodes in the hypothalamus, the thalamus, and the limbic area were studied in comparison with these activities in non-stimulated controls. In stimulating the ventromedial nucleus of the hypothalamus, the two-hour sessions were followed by significantly reduced activity in arginase and the arginine synthetase system in the liver, but the six-hour stimulation sessions were followed by normal range activity in these enzymes. In stimulating the lateral hypothalamic area, the two-hour sessions were followed by only slightly reduced activity in the arginine synthetase system in the liver. Stimulation of the center median nucleus of the thalamus, the medial area of the amygdala and the dorsal hippocampus produced no significant changes in urea cycle enzymatic activities in the liver. The possibility that ammonia metabolism in the liver may be modified through some functional linkage between the brain and the liver was suggested.
