Lu N, Zhang C.
PMID: 1535566
Zhongguo Yi Xue Ke Xue Yuan Xue Bao. 1992 Apr;14(2):85-8.

In clinical practice, it has been shown that the contrast sensitivity (CS) test is one of the most sensitive visual functional tests. In our experiment, we used a U.S.-made VCTS 60000 CS test plate to test the fellow eyes...

Impaired secretion of growth hormone-releasing hormone, growth hormone and IGF-I in elderly men.

Acta endocrinologica

Bando H, Zhang C, Takada Y, Yamasaki R, Saito S.
PMID: 2000699
Acta Endocrinol (Copenh). 1991 Jan;124(1):31-6. doi: 10.1530/acta.0.1240031.

The GHRH test and L-dopa test were performed in 12 normal young men (24.1 +/- 1.1 years) and 12 normal elderly men (77.8 +/- 1.4 years) to investigate age-related changes in secretion of GHRH, GH and IGF-I. The basal...

Chemical synthesis, cloning and expression of human epidermal growth factor gene in Saccharomyces cerevisiae.

Chinese journal of biotechnology

Yuan H, Min Y, Shi S, Tao W, Wu S, Li Y, Wang Q, Lu H, Zhang C, Hu Q.
PMID: 1668605
Chin J Biotechnol. 1991;7(4):253-61.

A gene coding for human epidermal growth factor (hEGF) has been chemically synthesized by solid-phase phosphoramidite method. The 173 base-pair synthetic DNA duplex consists of a structural gene encoding hEGF, a stop codon TGA at 3' end and some...

Mitochondrial DNA mutation associated with aging and degenerative disease.

Annals of the New York Academy of Sciences

Nagley P, Mackay IR, Baumer A, Maxwell RJ, Vaillant F, Wang ZX, Zhang C, Linnane AW.
PMID: 1485738
Ann N Y Acad Sci. 1992 Dec 26;673:92-102. doi: 10.1111/j.1749-6632.1992.tb27440.x.

Previous theories of aging based on somatic mutation neglected mtDNA, which has a high propensity for mutational error. Knowledge of yeast mtDNA mutations and their functional effects, and of human mtDNA mutations identified in the mitochondrial cytopathies, provides for...

[Bacterial microcolony and its primary applications].

Hua xi yi ke da xue xue bao = Journal of West China University of Medical Sciences = Huaxi yike daxue xuebao

Pei X, Ye M, Yin Q, Zhang C, Xu X.
PMID: 1304545
Hua Xi Yi Ke Da Xue Xue Bao. 1992 Sep;23(4):403-7.

A new rapid and useful microcolony technique was developed by using cellulose-acetate membrane as a supporter. The bacteria were inoculated on the membrane and cultivated for 3-6h. Then the membrane was rendered, fixed and colored. The microcolonies were observed...

An apparently allosteric effect involving N2O with the nitrous oxide reductase from Wolinella succinogenes.

Biochemical and biophysical research communications

Zhang C, Jones AM, Hollocher TC.
PMID: 1520293
Biochem Biophys Res Commun. 1992 Aug 31;187(1):135-9. doi: 10.1016/s0006-291x(05)81469-x.

It was shown that kcat for the benzyl viologen cation (BV+)-N2O oxidoreductase activity of nitrous oxide reductase from Wolinella succinogenes was 2-3 times greater at high N2O concentrations than at low. This effect of N2O on kcat exhibited a...

[Function of large plasmids of the plague pathogen].


Zhao MS, He Y, Zhang C.
PMID: 2178144
Genetika. 1990 Oct;26(10):1876-9.

Function of the largest plasmid of Yersinia pestis was studied. Assay of four strains of highly virulent Y. pestis isolated from different natural sources demonstrated that the characters of endotoxin production, sugar and alcohol fermentation, nitrate reduction as well...

Isoflurane alters the kinetics of oral cyclosporine.

Anesthesia and analgesia

Gelb AW, Freeman D, Robertson KM, Zhang C.
PMID: 2035864
Anesth Analg. 1991 Jun;72(6):801-4. doi: 10.1213/00000539-199106000-00015.

Cyclosporine is an important immunosuppressive agent often given orally preoperatively to patients undergoing organ transplantation. The aim of the present study was to evaluate the effects of anesthesia on the pharmacokinetics of orally administered cyclosporine. Sixty unanesthetized fasting female...

Effect of precursors on the synthesis of catecholamines and on neurotransmission in the superior cervical ganglion of the rat.

Journal of neurochemistry

Zhang C, Bordet S, Karoum F, Commissiong JW.
PMID: 2166775
J Neurochem. 1990 Sep;55(3):890-8. doi: 10.1111/j.1471-4159.1990.tb04575.x.

Male Sprague-Dawley rats (325-350 g) were anesthetized with urethane (1.5 g/kg i.p.) and treated with physiological saline, Aspartame (APM; 552 mumols/kg), or tyrosine (Tyr; 552 mumols/kg). Ganglionic transmission and the synthesis of dopamine (DA) and norepinephrine (NE) were measured...

[Electrophysiological effects of different dosage of adenosine triphosphate on normal sinoatrial and atrioventricular node].

Zhonghua xin xue guan bing za zhi

Zhang C.
PMID: 1473491
Zhonghua Xin Xue Guan Bing Za Zhi. 1992 Apr;20(2):98-100, 134.

In order to study the electrophysiological basis of smaller dosage that would terminate PSVT effectively and decrease side effects remarkably, we have observed the electrophysiological effects of ATP in different dosage (5mg, 10mg, 15mg) on the sino-atrial node (SAN)...
