    Notes: Summary The effects of serotonin on the formation of inositol phosphates and protein phosphorylation were examined in cultured smooth muscle cells. Serotonin stimulated the formation of [3H]inositol monophosphate, [3H]inositol bisphosphate and [3H]inositol trisphosphate. This effect was prevented by 5-HT2 specific antagonist, 6-methyl-1-(1-methylethyl)ergoline-8-carboxylic acid, 2-hydroxy-1-methylpropyl ester [Z]-2-butenedioate (LY53857). Serotonin stimulated the phosphorylation of many polypeptides, among which a 20 kDa polypeptide was the most prominent. The phosphorylation was also inhibited by LY53857. LY53857 alone produced no effects on protein phosphorylation. The 20 kDa polypeptides were also phosphorylated by the addition of 12-O-tetradecanoylphorbol-13-acetate. These results suggest that serotonin stimulates protein phosphorylation through 5-HT2 receptors and possibly activates protein kinase C in intact vascular smooth muscle cells.

    Notes: Abstract Nine women with primary ovarian failure, who were having their artificial menstrual cycles manipulated with physiological levels of estrogen and high doses of progesterone, were entered into the study. They filled in urinary symptom questionnaires and had urodynamic investigations in the two phases of treatment: estrogen and progesterone, and estrogen alone. The number of voids per 24 hours was significantly greater in the progesterone phase, as was the end filling pressure on cystometry. This is the first report in the literature of the effects of high-dose progesterone on the lower urinary tract.

    Notes: Abstract Situs inversus (SI) and the polysplenia syndrome (PS) occur relatively frequently in patients with biliary atresia, the largest subgroup of pediatric liver transplantation patients. We present two cases of orthotopic liver transplantation (OLT) in pediatric patients with SI. One had SI totalis, where a normal liver was placed in the left upper quadrant (LUQ) with the right lobe overlying the vertebral column. The second had PS and isolated SI of the liver, and a living-related left-lateral-segment graft was placed in the LUQ. Although multiple, often unpredictable vascular and intestinal anomalies occur frequently in association with SI, particularly in the setting of the PS, these cases, as well as several others recently reported, reveal that these anomalies can be managed successfully by a variety of technical modifications of the standard OLT technique. Likewise, concerns about the placement of a situs solitus liver in the midline or LUQ position of a SI abdomen have proved to be unfounded.
