Abstract
A 10-year-old boy with a de novo del(16)(q12.1q13) and many features of the deletion 16q phenotype is described. The deletion occurred in a paternal chromosome as demonstrated by DNA studies with polymorphic (AC)n microsatellite repeat markers. Comparison with published cases suggests that deletion of either of two regions (q13 and q22.1) on the long arm of chromosome 16 is associated with an apparently identical phenotype. No parental imprinting of this region was demonstrated.

Abstract
Using a peroxidase/anti-peroxidase immunohistochemical staining method, we examined sections of inflammatory synovial membranes from 13 patients with juvenile rheumatoid arthritis (JRA) and 11 with rheumatoid arthritis (RA). The relative numbers of TCR gamma/delta+ cells and the proportions of V delta 1+ and V delta 2+ subsets were recorded in the areas of the membranes most heavily infiltrated by CD3+ cells. In the JRA group, the majority (8/13) of the membranes had TCR gamma/delta+ cells which contributed between 5 and less than 10% of the total number of CD3+ cells. In the RA synovial membranes examined, 5/11 samples had between 5 and 10% TCR gamma/delta+ cells, but in another 5 TCR gamma/delta+ cells contributed to between 10 and 20% of CD3+ cells. No significant difference was noted between the two patient groups. However, the range of values found in the RA membranes appeared to be slightly higher in comparison to previously reported values for RA synovial fluid, peripheral blood and eluted synovial membrane T cells. Analysis of the relative proportions of the V delta 1+ and V delta 2+ subsets revealed a significant dominance of V delta 1+ cells in RA membranes and approximately equal numbers of the two populations in the JRA patients. As the majority of peripheral blood TCR gamma/delta+ cells use the V delta 2 segment this suggests a preferential homing or expansion of the V delta 1+ cells in both RA and JRA synovium. The overall distribution pattern of the TCR gamma/delta+ and V delta 1+ and V delta 2+ cells was also recorded. These cells mostly accumulated in the lymphoid-like tissues and in the perivascular area in the tissues of both RA and JRA patients. Occasionally, augmented numbers of these cells were found in the subsynovial layer or in the loose connective tissue. In the majority of cases, only a few TCR gamma/delta+ cells were located in the synovial layer. The function and the possible pathogenetic importance of these TCR gamma/delta+ cells have not so far been determined.

Abstract
A case control study to assess the possible risk factors associated with Alzheimer's disease (AD) among Chinese population was conducted on 126 clinical diagnosed AD patients and 252 matched by sex, age, nationality non-demand neighborhood as control. Factors significantly associated with AD cases were: family history of dementia in first degree relatives, family history of psychoses in first degree relatives, few interests and heavy negative life events during individual's life time. Neither family history of Down's syndrome, antecedent history of head trauma, nor other condition that might support immune hypotheses were significantly associated with AD cases. The data from this study support the familial/genetic hypotheses of AD and also the role of psychosocial factors in AD.

Abstract
DNA in macro- and micronuclei of Tetrahymena pyriformis treated with linear alkyl benzene sulfonate (LAS) and sodium pentachlorophenate (PCP-Na) were determined by microspectrophotometry. The effects on rate of formation of macronuclear DNA extrusion bodies were also studied. We found DNA content of micronuclei in 0.14 ppm LAS and 0.9 ppb PCP-Na was lower than in that of the control, and LAS was able to increase the formation rate of macronuclear DNA extrusion bodies (the formation rate was 54% in 11.3 ppm LAS and 25.6% in 16.7 ppm dichromate). We concluded that 0.14 ppm LAS (below the maximum acceptable toxicant concentration) was genotoxic, whereas 0.014 ppm LAS was not. Dichromate 0.05 ppm and 0.9 ppb PCP-Na, equal to and below the maximum acceptable toxicant concentration, respectively, were potentially genotoxic.

Abstract
A cosmid library of human chromosome 16 has been subcloned, and (AC)n microsatellite positive clones have been identified and sequenced. Oligonucleotide primers flanking the repeat were designed and synthesized for (AC)n microsatellites with n greater than 16. These microsatellite loci were then mapped by PCR using a somatic cell hybrid panel of human chromosome 16, and their heterozygosities and allele frequencies determined. Fourteen (AC)n microsatellites were mapped to discrete physical intervals of human chromosome 16 defined by a mouse/human hybrid panel. Nine of these have expected heterozygosities ranging between 0.60 and 0.79, four have expected heterozygosities between 0.02 and 0.49, and one detected three loci where the alleles could not be resolved.

Abstract
A highly polymorphic XbaI restriction site flanking the human 21-hydroxylase genes (21-OHA and 21-OHB) was found with the probe pC21/3c, the cDNA of the 21-hydroxylase gene. From the results of RFLP analysis of 10 subjects with congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency and their parents, at least four polymorphic fragments (30 kb, 27 kb, 25 kb, and 15 kb) resulting from cleavage at the polymorphic endonuclease sites outside the genes were found, and at least 10 different polymorphic patterns were observed among Chinese. These results indicate that these polymorphic loci are very informative for prenatal diagnosis of 21-hydroxylase deficiency.

Abstract
This study presents an observation of the anti-inflammatory effect of Aconitum carmichaeli decoction on water-immersion stress induced gastric ulcer in mice and 0.6 mol/L HCl induced gastric ulcer in rats. The observation showed that the decoction was resistant to the castor oil induced and Cassia angustifolia leaf induced experimental diarrhea in mice, and also had marked analgesic action. It is thus suggested that Aconitum carmichaeli is useful clinically as a spleen-stomach warming and analgesic agent in traditional Chinese medicine.

Abstract
OBJECTIVE To study the cytotoxic capacity of mycobacteria-specific T lymphocyte lines and clones from sites of inflammation in patients with rheumatoid arthritis (RA). We also studied antigen specificity, surface phenotype, expression of T cell receptors (TCR), and HLA restriction. METHODS Autologous macrophages (M phi) from the synovial membrane (SM), synovial fluid (SF), or peripheral blood (PB) were used as target cells in cytotoxicity assays. RESULTS All SM and SF cell lines tested thus far have shown specific lysis of the autologous M phi from SM or PB that had been pulsed with BCG (bacillus Calmette-Guerin), but no cytotoxicity when the targets were pulsed with irrelevant antigens such as tetanus toxoid and Chlamydia. Both CD4+ and CD8+ cells were shown to be involved in the specific cytolysis. The majority of the cytotoxic T lymphocyte (CTL) lines were TCR alpha/beta + cells. However, both TCR alpha/beta + and TCR gamma/delta + clones (TCR delta 1+) from one RA patient showed antigen-specific lysis. Antigen-specific recognition by a number of CTL lines and clones generated from SF and SM was restricted by HLA-DR molecules. Two Mycobacterium bovis 65-kd heat shock protein (HSP)-specific TCR alpha/beta + SF T cell clones also lysed M phi that had been pulsed with a recombinant human 65-kd HSP. CONCLUSION Joint inflammation and destruction might be partly attributable to a cross-reaction of mycobacteria-induced cytotoxic T cells with self HSP.

Abstract
The effects of short-chain fatty acids (SCFA) on ammonia net absorption from the sheep rumen in vivo and on ammonia transport across rumen wall mucosa in vitro were studied. Ammonia net absorption was directly, though in a non-linear manner, correlated with the SCFA concentration in the artificial rumen fluid. Almost 70% of total ammonia absorption was dependent upon the presence of SCFA when 12 mmol l-1 ammonia and 67.5 mmol l-1 SCFA were present. Lactic acid was ineffective. Incubation experiments showed that mucosal disappearance and serosal appearance of ammonia were reduced by 38% and 32%, respectively, when SCFA (63 mmol l-1) were replaced by lactic acid. The SCFA effect was independent of the type of SCFA used. In part of the experiments up to 54% of the ammonia taken up by the tissue was not recovered in the serosal incubation solution and must have been metabolized in the mucosa.

Abstract
From December of 1986 through February of 1990, digital subtraction angiography was performed on 156 patients, and specific diagnoses of congenital heart disease were made on the basis of information gathered by this imaging technique, supplemented by the physical examination. No other imaging techniques were used, for this was a prospective study designed to determine the accuracy of digital subtraction angiography alone in the diagnosis of congenital heart disease. When 80 of these 156 patients underwent subsequent operation, 75 were shown to have been diagnosed correctly, for an accuracy rate of 93.75%. Two patients died, for a mortality rate of 2.5%. The diagnostic value of digital subtraction angiography is discussed, as well as the compensative management of its artifacts.

Abstract
An experimental study using adult Kunming male mice was designed to observe the Shen reaction to trauma (bone fracture and burn). It was shown that the mice testes of the experimental groups were degenerated and the spermatogenesis disturbed. Under the electron microscope, the granules reduction, pyknosis, vesicular degeneration in the plasma of gonadotrophs and hemorrhage were found. It was revealed that the pathological changes of shen by trauma were mainly attacked on the adenohypophysis-gonadal axis. According to the results of this experimental study, the shen in the hypothesis of "trauma hurts shen" should be related to testes and ovaries (gonadal organs).

Abstract
We describe a highly polymorphic microsatellite repeat sequence, KLK1 AC, which is located 3' to the human glandular kallikrein gene (KLK1) at 19q13.3-13.4. A multiplex PCR was developed to simultaneously genotype the KLK1 AC repeat length polymorphism and a similar repeat at the adjacent APOC2 locus at 19q13.2. Genotypes from these two loci in the 40 large kindred pedigrees from the Centre d'Etude du Polymorphisme Humain were used in conjunction with the background genetic map to establish a multipoint linkage map. The KLK1 locus was also localized physically using somatic cell hybrid DNA templates for polymerase chain reaction analysis. Both genetic and physical mapping studies are consistent with the assignment cen-APOC2-KLK1-D19522-qter. The linkage map places KLK1 approximately 10 cM distal to APOC2. These markers therefore flank the myotonic dystrophy gene and may be useful for diagnosis.

Abstract
The long-term effects of haloperidol on phosphoinositide turnover in rat brain slices were investigated. Continuous treatment with haloperidol decanoate (21 mg/kg I.M. biweekly for 6 weeks) significantly attenuated carbachol- and norepinephrine (NE)-induced inositol phosphate accumulation in rat frontal cortex and hippocampus. In the striatum, the haloperidol treatment also significantly decreased carbachol-stimulated inositol phosphate level but did not significantly affect NE-sensitive phosphoinositide turnover. These effects were not observed in rats treated with a single dose of haloperidol (1.5 mg/kg). Basel levels of inositol phosphate in these 3 brain regions did not change following continuous or single haloperidol doses.

Abstract
To confirm the main etiological antigen of farmer's lung in Dafeng County, Jiangsu Province, People's Republic of China, precipitins in serum from 30 patients with farmer's lung were tested with several strains of antigens. Reactions against two strains of T.vulgaris were shown in 46.7% and 66.7% of the patients group, which were significantly higher than in the controls, while the percentage of reactions against Faenia rectivirgula and A. fumigates were low in the patients group and had no significant difference with the controls. The results indicate that the main etiological agents were some strains of T. vulgaris. This finding was consistent with the microbiological study of sputum of the patients and moldy hay samples from the working area.

Abstract
We describe two highly polymorphic microsatellite AC repeat sequences, VK23AC and VK14AC, which are closely linked to the fragile X at Xq27.3. Both VK23AC (DXS297) and VK14AC (DXS292) are proximal to the fragile site. Two-point linkage analysis in 31 fragile X families gave (a) a recombination frequency of 1% (range 0.00%-4%) with a maximum lod score of 32.04 for DXS297 and (b) a recombination frequency of 7% (range of 3%-15%) with a maximum lod score of 12.87 for DXS292. Both of these polymorphisms are applicable to diagnosis by linkage in families with fragile X syndrome. A multipoint linkage map of genetic markers at Xq27.3 was constructed from genotyping these polymorphisms in the CEPH pedigrees. The DXS292 marker is in the DXS98-DXS297 interval and in 3 cM proximal to DXS297.

Abstract
50 cases of acute myocardial infarction (AMI) were examined for ventricular late potential (VLP) six times in total within 4 weeks. At the same time the patients clinical condition was observed. It is found that: (1) In our group the occurrence of VLP in AMI was 28% and VLP was unstable in both acute stage and recovery stage. (2) During acute stage, the difference of positive VLP rate is significant between the ventricular fibrillation group and normal rhythm group (P less than 0.05), but there is no significant difference between the ventricular ectopia group and normal rhythm group. During recovery stage, the difference of positive VLP rate is very significant between the ventricular ectopia and normal rhythm group (P = 0.001). As there was only 1 case of ventricular fibrillation occurring in the recovery stage, no comparison could be made. (3) There is no correlation between VLP and clinical conditions, such as age sex, location of the infarction, existence of old infarction and LVEF. However, the difference of the peak serum CPK level is significant between VLP positive and negative group (P less than 0.05).

Abstract
In this study the absorption of Fe, Zn and Cu in decoctions of siwu decoction, sijunzi decoction and liuwei dihuang decoction by the small intestine in anesthetized rats was observed. The experimental results showed that the absorption of Cu and Fe from siwu decoction was much higher than that from other decoctions which might be related to the hematopoietic function of Cu and Fe rich in the decoction.

Abstract
The anti-anoxic experiments have indicated that the petroleum ether extract of Rhizoma Zingiberis can prolong the survival time in mice poisoned by KCN or under the condition of normobaric hypoxia, as well as decapitation-induced gasping duration in mice, but can not prolong the survival time in mice poisoned by NaNO4. The anti-anoxic action might be related to the reduction rate of O2 consumption of the body. The aqueous extract of Rhizoma Zingiberis does not possess the above-mentioned anti-anoxic action. Both extracts do not affect the survival time in cooled mice.

Abstract
Polymorphism of an XbaI restriction endonuclease site in intron 22 of the factor VIII gene was studied. 79 heredity-unrelated X chromosomes from 83 Chinese were analyzed. The frequency of the polymorphic site was 0.56, providing polymorphism information content (PIC) of 0.49. Fourteen out of 17 families with hemophilia A could be diagnosed by the Xba 1/22i restricted fragment length polymorphism (RFLPs). Therefore, as a genetic marker within the factor VIII gene, Xba I/22i RFLPs should be useful for prenatal diagnosis of hemophilia A and for detection of its carriers.

Abstract
The BcII polymorphism within DXS52 (St14) was reported. It was composed of 4 allelic fragments, 4.0 kb, 3.3 kb, 3.0 kb and 2.3 kb. The frequency of these fragment were 0.09, 0.12, 0.44 and 0.35 respectively in the Chinese. The polymorphism provided the PIC of 0.66. DNA analysis of families with hemophilia A showed that the confidence of the RFLPs was the same as the TaqI/St14 RFLPs and for carrier detection the former is much better than that of the TaqI/St14 RFLPs.

Abstract
The purD gene of Escherichia coli encoding the enzyme glycinamide ribonucleotide (GAR) synthetase, which catalyzes the conversion of phosphoribosylamine (PRA), glycine, and MgATP to glycinamide ribonucleotide, MgADP, and Pi, has been cloned and sequenced. The protein, as deduced by the structural gene sequence, contains 430 amino acids and has a calculated Mr of 45,945. Construction of an overproducing strain behind a lambda pL promoter allowed a 4-fold purification of the protein to homogeneity. N-Terminal sequence analysis and comparison of the sequence with those of other GAR synthetases confirm the amino acid sequence deduced from the gene sequence. Initial velocity studies and product and dead-end inhibition studies are most consistent with a sequential ordered mechanism of substrate binding and product release in which PRA binds first followed by MgATP and then glycine; Pi leaves first, followed by loss of MgADP and finally GAR. Incubation of [18O]glycine, ATP, and PRA results in quantitative transfer of the 18O to Pi. GAR synthetase is very specific for its substrate glycine.

Abstract
In rats, sectioning the fimbria-fornix leads to a decrease in cells reactive for acetylcholinesterase and choline acetyltransferase, as well as other types of cells, in the medial septal area that project to the hippocampus. In this study cells in the medial septal area were stained for acetylcholinesterase reaction product or by a Nissl method two weeks after unilateral section of the fimbria-fornix. Counts were made of cells on each side of the midline by independent observers. The counts of the cells on the two sides of the brain were compared in rats that had been given nimodipine (70 μg/kg) just after the lesion and for 7 additional days and in rats that had been given only the vehicle for an equivalent amount of time. The number of cells reactive for acetylcholinesterase was reduced in the medial septal area on the side of the brain in which the forebrain fornix was sectioned, but this occurred to a significantly less extent in the nimodipine-treated rats. No differences were noted in the number of cells on the two sides of the medial septal area when counted in Nissl-stained sections.

Abstract
Hemophilia A is the most common inherited bleeding disorder in man. The disease is caused by a deficiency in the gene for factor VIII. A genetic marker in the form of RFLP within or tightly linked to the factor VIII gene may serve as a tag for the hemophilia gene, thus allowing both accurate carrier detection and earlier prenatal diagnosis. Five RFLP (BclI/FVIII-e18, XbaI/FVIII-i22, BclI/St14, TaqI/St14 and BglII/DX13), which are related to hemophilia gene, were studied. The frequencies of allele of TaqI/St14 and BglII/DX13 in Chinese are obviously different from those in Caucasian. By the use of RFLP, 21 families with hemophilia A were analysed. The feasibility and strategy of gene diagnosis of hemophilia A by the use of RFLP are discussed.

Abstract
A new method is discussed which examines trace, dried bloodstains by gel in situ hybridization using a Y-chromosome-specific deoxyribonucleic acid (DNA) probe to determine the sex of the bloodstain for forensic medicine application. The complete DNA is transferred directly by electrophoresis onto the gel intact, bypassing the possibilities of impurities contaminating the sample and of DNA degradation. The method has proven accurate for small (2.5-mm-diameter) samples aged up to eight years and is quick, simple, and easily read.

Abstract
Radiotherapy and chemotherapy are two important methods for malignant tumor treatment. To research radiobiological response in therapy, we have established a better experimental method in contrast to the traditional ones such as TCD50, regrowth delay, cell survival curve, etc, all with their limitations. A new mouse tumor in vivo-in vitro system LA795 Vv-Vt has been developed for studies on radiobiology. Such a system could be used to study the in vivo response of a solid tumor by the in vitro cloning assay. For the purpose of increasing the PE in vitro, LA795 Vv-Vt tumor line was purified through culturing the cells as a clonogenic spheroid. The spheroids were then injected into the flank of mouse subcutaneously for tumor growth. The in vivo-in vitro system LA795 Vv-Vt is an excellent model dissecting and analyzing the various factors which affect tumor development and determine the response of tumor to specific agent and regimens.

Abstract
Extracts from a group of destagnative herbs, 764-1, and the effective chemical, 764-3, were tested by an in vitro experiment using a HeLa-S3 cell line. Under aerobic conditions, the shoulder of the cell survival curve diminished or disappeared according to the different doses of 764-1 used, but no change in slope was observed. In nitrogen, when the dose of 764-1 increased to 20 mg/ml (ID20), besides the disappearance of the shoulder, the slope of the curve also showed changes at lower doses (4-8 Gy); up to 10-25 Gy the curve became more flattened. 764-3 showed almost a similar effect by mainly affecting the shoulder of the survival curve. At low drug doses a SER as high as 1.87 might be obtained under hypoxic condition. At the same time 764-1 was used in testing the effect on radiation lung damage. It was found that 764-1 could markedly inhibit the change of alveolar surfactant at 1 and 3 weeks after radiation. A wide field of investigation is thus spread out in front of us on radiosensitization and protection. Further studies on 764-3 are carried out.

Abstract
A new method for labeling oligonucleotides was developed to obtain high specific activity of radioactive probes. In an oligonucleotide molecule, two sequences were designed. One sequence, the 5', contains 19 nucleotides and serves as a template for probe synthesis. The second sequence, 3', contains a consensus sequence which forms a Pst I site after forming a complementary strand with the primer. In the presence of E. coli DNA polymerase I (Klenow fragment), alpha-32P dNTP and other dNTPs, a radioactive labeled oligonucleotide was synthesized by the primer extension method. After Pst I digestion, the probe was different from its template in length by 4 bp and could be separated from each other on urea-polyacrylamide gel electrophoresis (PAGE). A radioactive oligonucleotide probe with extremely high specific activity up to 10(10) dpm/micrograms could be obtained by the use of this method. The oligonucleotide probes have been used for the detection of the Hb E mutation in this report.
