Ventriculoperitoneal (VP) shunt is one of the most common pediatric neurosurgical procedures. It has various complications that may have serious consequences such as shunt dysfunction, and unusual migration. Although, migration of shunt catheter to bladder, heart, umbilicus, rectum, pulmonary artery, and stomach has been reported, migration to vagina is a rare one.In this report we present a 16...

The results of studies on the influence of age on concentrations of vasopressin (VP) in blood plasma and hypothalamic and extrahypothalamic brain sites have not been unequivocal. Studies on extrahypothalamic concentrations of VP in the aging rat have used two age groups only and have mainly provided semiquantitative data. For these reasons we determined, by radioimmunoassay, the concentrations ...

Nitric oxide (·NO) was originally identified as an innate cytotoxin. However, in tumors it can enhance resistance to chemotherapy and exacerbate cancer progression. Our previous studies indicated that (·NO/·NO-derived species react with etoposide (VP-16) in vitro and form products that show significantly reduced activity toward HL60 cells and lipopolysaccharide (LPS)-induced macrophages. Here, ...

The ventral pallidum (VP) is a key component of the neural circuitry mediating relapse to drug seeking, but the critical afferent pathways to VP recruited during relapse remain poorly understood. We studied the role of the nucleus accumbens core (AcbC) ¡ VP pathway in ABA renewal and reacquisition of alcohol seeking. Rats received application of adenoviral vectors encoding eYFP, ChR2(H134R), or...

BACKGROUND This study evaluated the effect of vege-powder (VP), mainly consisted of chicory, broccoli, and whole grains, on bowel habit improvement and constipation alleviation. METHODS Using the Roman standard II, 96 male and female subjects in their twenties with constipation symptoms were divided into a control group or VP group. Subjects in a control group were supplied with rice flakes-p...

In this study, we determined in vivo interactions between hemopoietic growth factors and etoposide (VP-16) to assess whether normal blood cell production could be maintained during chemotherapy if hemopoietic growth factors were simultaneously administered. Groups of mice were treated for 7 consecutive days with four different doses of VP-16 in combination with three different doses of erythrop...

Prior sodium restriction cross-sensitizes rats to the psychomotor effects of amphetamines and vice versa. Repeated central injections of vasopressin (VP) induce a psychomotor sensitization similar to amphetamine sensitization and repeated sodium deficiency. Thus brain VP signaling may be a common mechanism involved in mediating these two motivational systems. In experiment 1, we tested the hypo...
