Objective To investigate the effects of malnutrition, nephrosis itself and glucocorticoid therapy on serum IGF-l and liver IGF-l mRNA, and illustrate relationship between growth failure in nephrotic rats and turbulence of serum IGF-l. Methods Twenty-four male SD rats were randomly divided into control, pair-fed, doxorubincin-induced nephrotic(nephrotic) and dexamethasone-treated nephrotic (des-treated) rats. Serum IGF-1 and liver IGF-l mRNA were measured by RIA and RT-PCR respectively. Results 1. Serum IGF-l was reduced and liver ICF-l mRNA was increased in pair-fed and nephrotic rats, but no significant difference was found between two groups. 2. Serum IGF-l and liver IGF-l mRNA were lower in des-treated rats than in nephritic rats. 3. There was a positive correlation of serum IGF-l with nose-tail length and weight. Conclusions Reduced serum IGF-1 induced by secondary malnutrition is the cause of growth failure in nephrotic syndrome. Glucocorticoid therapy deteriorates growth failure in nephrotic syndrome by further decreased liver IGF-1 synthesis.

Objective To investigate the effects of malnutrition,nephrosis itself and glucocorticoid therapy on serum thyroid hormone,illustrate the relationship between serum thyroid hormone and renal IGF-I/IGFBPs autocrine/paracrine in nephrotic rats.Methods Twenty-four male Sprague-Dawley(SD) rats were randomly divided into control,pair-fed,doxorubicin(5mg/kg)-induced nephrotic and dexamethasone treated nephrotic(des-treated) rats.Serum T 3,T 4 and GH were measured by RIA,renal GHR and IGF-I/IGFBPs mRNA were analyzed by radioreceptor assay and RT-PCR respectively.Results ⑴Serum thyroid hormone levels were decreased by degrees according normal rats,pair-fed rats,nephrotic rats and lowest in des-treated rats except for high serum T 4 in pair-fed rats showed increasing trendency.⑵Reduced serum thyroid hormone was parallel well with decreased renal GHR and IGFBP-2 mRNA,and correlated negatively with increased renal IGFBP-3 mRNA.⑶There was some significant correlation positively between nose-tail length or weight and serum thyroid hormone.Conclusions The hypothyroidism is a possible mechanism of IGFBPs autocrine/paracrine disorder and further growth retardation in nephrotic syndrome.

Objective To investigate the effects of malnutrition, nephrosis itself and glucocorticoid therapy on serum growth hormone binding protein(GHBP) and liver growth hormone receptor(GHR), and elucidate the relationship between growth failure in nephrotic rats and serum GHBP or liver GHR. Methods Twenty-four male Sprague-Dawley(SD) rats were randomly divided into control, pair-fed, doxoruhincin-induced nephrotic (nephrotic) and dexamethasone-treated nephrotic (des-treated ) rats. Serum GHB P, GHB P- 1 and liver GHR were measured by dextran-coated charcoal technique, gel filtration and radioreceptor assay respectively. Results (1) Serum GHBP and liver GHR were reduced in nephrotic and des-treated rats compared with control and pair-fed rats, but no significant difference was found between control and pair-fed rats or between nephrotic and des-treated rats. (2)Serum GHBP-1 was lower in pair-fed rats, even lower in nephrotic rats and lowest in des-treated rats than in control. (3) There was some significantly positive correlations between nose-tail length or weight and serum GHBP or liver GHR. Conclusion GH resistance, due to decreasd liver GHR, is an important cause of growth failure induced by secondary malnutrition and nephrosis itself Glucocorticoid therapy deteriorates growth failure by further decreased hepatic GHR.

Objective To study the neuropathological changes of gastrin and substance P(SP) in the intermuscular and submucous nerve plexus of the colonic walls in patients with delayed motor constipation(DMC). Methods Gastrin and rabbit SP polyclonal antibiotics were used to make an immunohistochemical staining of the samples of different segments obtained from 10 patients with DMC and 8 normal subjects(control group) for a comparative observation as well as a relative semi-quantitative analysis. Results The immune positive nerve cells of gastrin and SP in the intermuscular nerve plexus of colon with DMC were markedly reduced; no differences in the immune response of gastrin and SP in the mucous nerve plexus were found between the two groups(P＜0.01). With routine HE staining, focal inflammation occurred in the mucous membrane of DMC colon and that the neuronal vacuolus of the intermuscular nerve plexus degenerated, reduced and even disappeared. Conclusion The abnormal changes of the neural structure in the immune reponse of gastrin and SP in the intermuscular nerve plexus of colon with DMC might be related to reduction of gastrin and SP peptide neuron or dysfunctional.

DNA in the livers of rats was isolated 24 h af-ter oral administration of benzidine, Congo red andEvan's blue, DNA adducts in the livers of ratswere investigated by a ~(32)P-postlabeling assay. Thelevel of DNA adducts in the livers of rats after oraladministration of benzidine, congo red andEvan'blue were 18. 17, 1. 03 and 1. 74?mol/kgDNA respectively. The results showed that themetabolites of the benzidine derivative azo dyes canform adducts with DNA in the livers of rats.These DNA adducts probably are one of the rea-sons that the incidence of the bladder cancer rosein the people group who are only exposed to benzi-dine derivative azo dyes.
