[EX Q]: Abstract: A new right hemisphere symptom is reported. Five stroke patients with lesions in the perisylvian cortico-subcortical or thalamic region of the right hemisphere produced linguistically correct but semantically loose writing. The behaviour was initiated by subtle prompting and continued semiautomatically. A possible mechanism underlying this hypergraphia is discussed.

[EX Q]: Abstract: The effect of tauroursodeoxycholate (TU) infusion on the plasma level and biliary transport maximum (Tm) of sulfobromophthalein (BSP) was examined in male rats during a continuous intravenous infusion of BSP with different TU infusion rates. The infusion rate of 0.6 mumol/min/100 gm body weight of TU caused significantly higher bile flow and BSP Tm values compared with the respective control values in rats with only a BSP infusion. These values, however, were significantly lower than values obtained by an equimolar infusion of taurocholate (TC). The higher infusion rates of TU (1.2 and 1.8 mumol/min/100 gm) tended to cause higher bile flow rates, but the BSP Tm value did not increase beyond the value obtained at the lower infusion rate (0.6 mumol/min/100 gm). In the highest TU infusion rate study (1.8 mumol/min/100 gm), plasma BSP concentrations were significantly higher than corresponding control values or values at a lower TU or TC infusion rate. It was concluded that in rats TU can significantly increase the BSP Tm, but to a lesser extent than TC. Furthermore, it was suggested that TU infusion at a higher rate significantly interferes with the hepatic uptake (or storage) of BSP.

[EX Q]: Abstract: Sex steroids have been shown to have a marked effect on the physiologic activities of the liver and the gastrointestinal tract. We performed autoradiographic studies using [3H]estradiol and [3H]dihydrotestosterone on male and female baboons for the purpose of identifying estrogen or androgen receptors, or both, in the liver, pancreas, stomach, and small and large intestines of baboons. Evidence for the presence of estrogen and androgen receptors was made apparent by high concentrations of silver grains over the nuclei of the cells of these tissues. Androgen receptors were largely confined to the nuclei of the smooth muscle cells of the tunica muscularis of the gut wall and the connective tissue interstitial cells of the liver, pancreas, stomach, and intestines. Estrogen receptors were prominent in the nuclei of the vascular smooth muscle cells in the liver, pancreas, gut, and the majority of the endocrine islet cells. These observations suggest that a variety of different cell types of the liver, pancreas, and gastrointestinal tract contain estrogen and androgen receptors that might modulate their cellular activities and influence several different physiologic processes.
