This paper reports the elution test of adhering villus on a slide to detect the (?)uman chorion ABO(H)substance of the blood. A preliminary study of sample taking conditions and sample preservation was made for the experiment. The results show that the elution test needs less villi(2-4mg)and is easier to conduct, as compared with other methods. The method is of practical value in identifying the disputed (?)aternity in the early pregnancy. When kept properly in refrigeration, the smaple of chorion cart be kept as long as 3 months.

30 chorinic villi in early pregnancy (8-10 weeks)and their parent blood samples were analysedusing the method of restriction fragment length polymorphisms with single locus DNA probes of PAC255 and PAC256. Based on the gene frequencies of these two loci in Chinese and the relativechance of obligatory gene in each triplet, the cumulative parternity index and cumulative relativechance of paternity were calculated. The range of the former is 56. 80- 8333. 50, and the later is 98.27 - 99. 99 %. According to the international standard of paternity test, in the 30 pedigrees, 20 cases(66. 7 % )were assured for their paternity. It is showed that the combination of PAC255 and PAC256single locus DNA probes for the paternity test of early pregnancy is very available.

In Cantharidin-poisoned rats, nicotinamide-adenine dinucletide dehydrogenase (NADHD) andcytochrome oxidase (CCO) activities of myocardi-um, stomach and intestine were observed in exper-iment histochemically. The result showed thatNADHD and CCO reaction granules were de-creased, stained weakly, and distributed sparselyin myocardium, stomach and intestine of intoxicat-ed rats as compared with the control group. Thus,from the experimental result it was considered thatcantharidin may inhibit the activities of NADHDand CCO in varving degrees.

Based on the histochemical observation ofnicotinamide adenine dinucleotide dehydrogenase(NADHD) and eytochrome oxidase (CCO) activi-ties of myocardium in cantharidine poisoned rats,furthermore, we observed the changes of these en-zymes of the myocardium cytochemically. The re-sult showed that, compared with control group, NADHD and CCO activities were inhibited afteradministration of cantharidin 1 or 2 h, and the in-hibition was found to be more obvious with poison-ing times prolonged, after 24 h, the cristae of mi-tochondria can not be distinguished, and the reac-tion products diffued into stroma to become a ho-mogeneous mass and lost their normal localization.It is indicated that cantharidin might destroy thestructure of mitochondria and interfere the activi-ties of NADHD and CCO of which both are locatedon mitochondria.

The specific binding capacity of androgen receptor (AR)and estrogen receptor (ER)in the peripheral lymphocytes was estimated by radioligand binding assay in 130 diabetic patients (type Ⅰ 18 cases and type Ⅱ 112 cases). Results were as follows:1)plasma estradiol (E2) of diabetic patients was significantly lower than that of the controls (P

Objective To explore the mechanism of VEGF treating cerebral ischemia. Methods A rat model of middle cerebral artery occlusion (MCAO) was set up by nylon suture embolization. The naked plasmid DNA encoding vascular endothelial growth factor(pUCCAGGS/hVEGF 165 ) was directly injected through skull into the ischemic areas of brain. After seven days the rats were killed. RT-PCR was used to measure the expression of VEGF mRNA in the brain tissues, and immunohistochemistry was appllied to detect the expression of VEGF, Fas and Fas L in the brain tissues. Results Compared with control group, VEGF expression significantly increased in the therapeutic group(P

Bioethnopharmaceutical analytical pharmacology (BAP) means to study Chinese herbal compound formula (CHCF) from the aspacts of in vivo and in vitro efficacy,pharmacodynamics,quality control and plant chemistry,guided by the CHCF absorbed bioactive compounds (ABC) analyses.The form of BAP is performed by comparing ABC efficacy with mother formula efficacy.Meanwhile,it must follow the principle which the ABC dose should be equal to the mother formula content or the blood drug concentration.In this study,the hypothesis was put forward to clarify the thoughts,assumptions and expected results,which uncovered the multiple cardioprotective mechanism of Dangui-Buxue Tang (DBT) for ischemic heart disease.BAP is expected to guide the development of further experiments for providing a better thought for the research over CHCF.

Objective:To examine whether somatostatin analogous(SSAs) have effect on Graves ophthalmopathy and to compare its effects with that of glucocorticoid.Methods: Both a computer aided search of MEDLINE and Chinese Biological Medicine disc and an intensive search by hand were conducted to identify all controlled studies assessing the effect of SSAs on Graves ophthalmopathy.Results: Five studies were finally included.Three of them found SSAs to be significantly more effective than placebo;2 of them found SSAs to be able to reduce proptosis; 2 of them found SSAs to be equally effctive as glucocorticoid.The pooled OR, pooled mean difference, pooled OR were 0.070.02,0.23],-1.47 -2.10,-0.84] and 0.95 0.25,3.59] respectively.Conclusion: This Meta analysis demonstrates that SSAs are effective in treatment of Graves ophthalmopathy and in reduction of proptosis, and it is equally effctive as glucocorticoid.

Objective: To examine whether the progression of early diabetic renal disease with normotension can be slowed by ACE inhibitors(ACEI). Methods: MEDLINE and Chinese Biological Medicine Disk were searched for randomized controlled trials about the effect of ACE inhibitors on patients with normotensive early diabetic renal disease from January, 1990 to April, 1999. According to included criteria, 10 studies were chosen at last.Data were combined by RevMan 3.1 software. Results: The pooled effect sizes of urinary microalbuminuria excretion rate, systolic blood pressure, diastolic blood pressure and mean arterial blood pressure were -77.502 mg/24 h[-100.748,-54.256], -5.002 mmHg [-9.630, -0.685 ], -2.949 mmHg[-4.005, -1.892], -4.284 mmHg[-5.444, -3.123] respectively. Regarded progression to clinical albuminuria as end point,the pooled OR(odds ratio) was 0.27[0.18,0.40]. The sub category analysis showed no differences between type 1 and type 2 diabetes.There were no significant correlations between the pooled effect of urinary microalbuminuria excretion rate and systolic blood pressure, diastolic blood pressure or mean arterial blood pressure. Conclusion: ACE inhibitors can decline urinary microalbuminuria excretion rate in patients with normotensive early diabetic renal disease and delay the progression of early diabetic renal disease to clinical albuminuria, and the effects may not depend on its blood pressure reduction effect.

Objective To get the basic data of nasal figure of the Han nationality individuals in Xi'an area and provide for junsprudence and the reconstruction of skull. Methods Nasal height, length, depth and breadth of 313cases in Xi'an area, which had different age and sex, were measured by magnetic resonance imaging (MRI). Results Image of MRI could clearly show the figure of nose and the position we selected were correct and accuracy. The specific data were: Nasal length (male:34. 47±4.29 ～52.20±3.47, female:33. 11±3.33～46. 94±3.83); Nasal height(male: 39.22±3.68～59.49±2.30, female: 33.89±3.95～51.75±3.68); Nasal depth(male: 11.89±1.76～16.68±2.48, female: 10.69±1. 81～16.46±2.04);Nasal breadth(male: 33. 09±3. 83～42. 49±2.72,female:32.00±1.94～38. 86±2.61). So the results were credible. Conclusion The nasal figure of individuals in Xi'an area is different as their different age and sex. It promotes that the influence factors of age and sex must be considered in the facial reconstruction and medico legally reconstructing skull.
