Fifty-seven cadaveric renal transplantations in fifty-five cases were analysed of them, thirty cases were prepared by continuous ambulatory peritoneal dialysis (CAPD group); twenty-seven transplantations in twenty-five cases were prepared by hemodialysis (HD group). Our data show that there is no significant difference in the survival duration between CAPD group and HD group; that there is also no significant difference in the survival duration between the two groups treated with the same immunosuppressive drugs, and that patients prepared by CAPD have a low risk of peritonitis after transplantation. It is better not to remove the Tenckhoff catheter until the graft function is stable so that it can be used for the transient peritoneal dialysis in the case of the insult of graft function or for the sampling of the peritoneal effusion for diagnosis of suspectable peritonitis after renal transplantation.

The prediction of anatomical morphology of primary aldosteronism using serum 18-hydroxycorticosterone levels.

Serum 18-hydroxycorticosterone, aldosterone, and potassium were measured under basal conditions in 34 patients with documented primary aldosteronism, 10 patients with essential hypertension, and 9 normal subjects. The results revealed that 22 of 23 patients with aldosterone-producing adenomas had 18-hydroxycorticosterone levels greater than 100 ng/dl, and all 9 patients with idiopathic adrenal hyperplasia had plasma levels less than 100 ng/dl. Two patients with unusual macromicronodular hyperplasia of the adrenal glands had levels greater than 100 ng/dl. We found a significant relationship between serum potassium and the ratio of 18-hydroxycorticosterone to aldosterone in patients with idiopathic adrenal hyperplasia, but not in those with an aldosterone-producing adenoma. We conclude that measurement of serum 18-hydroxycorticosterone is a useful predictor of the etiology of primary aldosteronism.

Heterogeneity in induced heat resistance and its relation to synthesis of stress proteins in rat tumor cell clones.

Tumor cell clones isolated from a rat 13762NF mammary adenocarcinoma and its spontaneous metastases were heterogeneous in their survival responses to continuous 42 degrees heating. Clones MTLn3 and MTF7 had similar initial survival responses; they were significantly less sensitive than clone MTC. Following the first decrease in survival, different magnitudes of induced thermal resistance were observed. When ratios of the first and resistant slopes of survival curves were compared (the thermotolerance ratio), the order of induced thermal resistance was MTLn3 greater than MTF7 greater than MTC. These clones were compared for the rates of synthesis of heat stress proteins (HSP). The same four major HSP at Mr 112,000, 90,000, 70,000, and 22,000 were induced or enhanced in all 3 clones. The rates of synthesis of these HSP were analyzed through a unique system of computer-assisted video densitometry and digitization. When all 4 HSP were analyzed as a group, the rates were significantly different (p less than 0.017), and the rank order of rates of synthesis was significant with MTLn3 greater than MTF7 greater than MTC. Induction kinetics of the individual HSP were different. Individually, the HSP at Mr 112,000, 90,000, and 22,000 were synthesized at significantly different rates between clones (p less than 0.001) but the Mr 70,000 HSP was not. Absolute total protein synthesis was highest for clone MTLn3, and MTF7 was higher than MTC but only marginally. Although absolute accumulations of these HSP could not be directly compared between these clones, the higher rates of HSP synthesis in these tumor cell clones correlated with more thermal resistance. These data support the working hypothesis that one or more of these HSP have a direct role in the mechanism(s) for inducing thermal resistance in rat tumor cells, but other factors such as total protein synthesis could modify the complex bio-chemical and phenotypic pathways involved in induced HSP and thermal resistance.

Relation between glucose, insulin, and growth hormone in the fetus during labor and at delivery.

Maternal, fetal and umbilical blood glucose, insulin, and human growth hormone (HGH) levels were measured to determine their relation during labor and at delivery. There was a positive correlation between fetal glucose and HGH, as well as between the fetal insulin and HGH values. Higher birthweights were associated with lower umbilical venous HGH and higher insulin levels. Thus, the balance between insulin and growth hormone might be involved in the regulation of fetal growth.

[Identification and characterization of differentially expressed ESTs of Gossypium barbadense infected by Verticillium dahliae with suppression subtractive hybridization].

Cotton wilt defense reaction is a complicated continuous process and involves a battery of genes. In this study, we adopted suppression subtractive hybridization (SSH) technique to isolate differentially expressed ESTs from Gossypium barbadense variety 7124 during Verticillium wilt defense process. An array of 1165 clones from the subtractive library has been screened with reverse northern blotting, of which 131 ESTs were considered as over-expressed and 16 ESTs were down-regulated. Sequence analysis and blast search showed that 83 ESTs were homologous to 45 unique sequences in the databases. Among all these differentially expressed ESTs, at least three kinds of genes were characterized. The majority of ESTs with deduced identity to aerobic metabolism enzymes strongly expressed in the infection process. Likewise, ESTs similar to those reported for pathogen-related protein genes were also picked out in this study. These ESTs in combination with other kinase-like genes and a defensin-like EST constituted an assembly of genes responded during pathogens' infection. These results imply that sea-island cotton undergoes strong oxidative stress and results in a series of defense responses when attacked by V. dahliae. To our knowledge, this is the first report on the isolation of global ESTs during sea-island cotton defense reaction.

Testosterone feedback on gonadotropin secretion and gene expression in transgenic mice expressing human growth hormone gene.

To determine the effects of testosterone on the regulation of gonadotropins in metallothionein-1/human growth hormone (MT/hGH) transgenic mice, basal and gonadotropin-releasing hormone (GnRH)-stimulated luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release from incubated pituitaries, as well as pituitary content of LH, FSH, and mRNA for their respective beta subunits, were measured in normal and transgenic males that were injected with testosterone propionate (5 micrograms/g body weight; 24 hours before autopsy), injected with oil vehicle, castrated for 10 days, or sham operated. In normal (non-transgenic) males, exogenous testosterone induced the expected suppression, and castration induced the expected stimulation of various parameters of gonadotropin synthesis and release. In contrast, in testosterone-treated and in castrated MT/hGH transgenic mice the release of LH and the pituitary levels of LH-beta mRNA did not differ from the corresponding values measured in vehicle-injected and sham-operated transgenic controls. Pituitary LH content was elevated in testosterone-treated MT/hGH transgenic mice but was not changed in castrated transgenic males. The changes in pituitary levels of FSH and FSH-beta mRNA and in FSH release in MT/hGH transgenic mice in response to testosterone and castration were different from the changes in LH and LH-beta mRNA in the same mice, but similar to the changes of FSH and FSH-beta message produced in normal mice by identical treatments. We suggest that hGH expression attenuates the effects of testosterone on the mechanisms controlling LH release, with less influence on testosterone regulation of LH synthesis. These effects of hGH expression appear to be selective for LH, without influencing the FSH control system.
