The comparative anatomical study of the parietal region of the skull of the Korean native goat (Capra hircus)

In the skull of the Korean native goat, the parietal region was classified into four types by the degree of the fusion of the bones, the os interparietale, the os parietale and the squama occipitalis of the os occipitale, and the structural variations of these fusions. The fusion appeared first in the sutura interparietoparietalis and that of the sutura sagittalis of both ossa parietalia was followed. There was no fusion between the os parietale and the squama occipitalis of the os occipitale. These results suggest that the os interparietale developed independently but fused to the os parietale after birth, and the os parietale were developed as paired bones in prenatal life and then fused together according to age.     

Intrapreneurial nursing: the Comprehensive Lower Extremity Assessment Form

The Comprehensive Lower Extremity Assessment Form was developed in response to the need for a screening tool in a nurse-managed foot care clinic. It differs from other such tools because it includes clinical measures that identify the potential for foot pathology. The Comprehensive Lower Extremity Assessment Form also serves as an assessment teaching guide in a foot care course and is included as part of a home-study program. The authors demonstrate how the Comprehensive Lower Extremity Assessment Form has generated revenue as part of an intrapreneurial outgrowth of their foot clinic and provides a comprehensive approach to lower extremity assessment. The form can be tailored to meet the needs of the advanced practice nurse, the clinical setting, or patient population.

The effect of promethazine hydrochloride on bilirubin metabolism in the rat

The effect of 21 days of promethazine-HC1 administration on hepatic bilirubin metabolism and transport was studied in adult rats. A significant increase in mean cumulative hepatic bilirubin uptake (84.5 +/- 7.6 (SE) mug/100 g/min in controls vs. 110.0 +/- 4.3 in treated rats), mean hepatic glucuronide conjugation (1,330 +/- 86 (SE) mug bilirubin conjugated/g liver/40 min in controls vs. 1.713 +/- 61 in treated rats), and mean maximal hepatic excretion (47.2 +/- 4.9 (SE) mug/100 g/min vs. 63.5 +/- 2.7) was observed in treated animals. Mean total liver weight and total hepatic protein also increased significantly. These observations suggest that promethazine is an inducer of protein and enzyme synthesis in rat liver and is capable of significantly stimulating the three major steps in hepatic disposal of bilirubin.     

Surface activation of carbon film supports for biological electron microscopy

The effect of glow-discharging on maked carbon-filmed grids has been evaluated. The effect of different locations of the grids within a DC discharge, operated in the normal glow, was analyzed by applying various biological specimens to the grids. Two locations were found to give consistent results: (a) in Crookes dark space, particulate specimens, negatively stained, spread evenly — suggesting a net negative surface charge of the support; (b) below the anode, nucleic acids, selectively (positively) stained, appeared as well spread filaments, indicating a net positive surface charge.     

Human CD5 signaling and constitutive phosphorylation of C-terminal serine residues by casein kinase II

CD5 is a lymphocyte surface glycoprotein with a long cytoplasmic domain suitable for phosphorylation and signal transduction, which is involved in the modulation of Ag-specific receptor-mediated activation and differentiation signals. In this study, we use Jurkat T cell transfectants of CD5 cytoplasmic tail mutants to reveal phosphorylation sites relevant to signal transduction. Our results show that casein kinase II (CKII) is responsible for the constitutive phosphorylation of CD5 molecules at a cluster of three serine residues located at the extreme C terminus (S458, S459, and S461). Furthermore, the yeast two-hybrid system demonstrates the specific association between the C-terminal regions of the CD5 cytoplasmic tail and the regulatory beta subunit of CKII. We demonstrate that CKII associates with and phosphorylates the C-terminal region of CD5, a conserved domain known to be relevant for the generation of second lipid messengers, and thereby enables at least one component of its signaling function.     

Prostaglandins in liver disease and liver transplantation

This brief review summarizes the physiology and pharmacology of eicosanoids and describes how they have been tested for possible application in liver disease and transplantation. The objective is to trace the stepwise application from the laboratory to the bedside. Although many questions remain to be answered, the observations summarized in this article have opened up new and potentially rewarding prospects in application to liver disease.
