Abstract
Indinavir is a member of a class of protease inhibitors that actively prevent the acquired immunodeficiency syndrome virion from maturing. A high-performance liquid chromatographic (HPLC) assay was developed and validated for the determination of indinavir in human plasma. Indinavir and the internal standard were isolated from the plasma by ether extraction. The residue after evaporation of ether was reconstituted with buffer and injected onto a C4 reversed-phase column eluted isocratically with a mobile phase consisting of 35:65 (v/v) of acetonitrile and buffer. A wavelength of 210 nm was found to be optimum for detection. The calibration range of this assay was from 10 to 5000 ng/ml and coefficients of variation for the assay ranged from 4.6% to 11.0% for three different drug concentrations and the limit of quantitation was 10 ng/ml. During the validation, short-term stability of the drug in plasma, stability during heat deactivation and on repeated freezing and thawing of plasma was evaluated. The overall recovery of indinavir by the ether extraction method was 91.4%. This HPLC assay was found to be a simple and reproducible method for monitoring indinavir levels in human plasma obtained during clinical trials of the drug.

Abstract
A multiexponential model of cavity ring-down absorption spectroscopy is established for taking into account the laser linewidth effects. It is demonstrated that by fitting the logarithmic ring-down function to a truncated polynomial, absorption coefficent can be extracted from coefficients of the first as well as higher order terms of the fitted polynomial. The new fit model results in higher accuracy and broader dynamic range than the previous single exponential model.

Abstract
A hammerhead ribozyme [R(-)] targeting the minus strand RNA of potato spindle tuber viroid (PSTVd) and a mutated nonfunctional ribozyme [mR(-)] were designed, cloned, and transcribed. As predicted, both monomer and dimer transcripts of the active R(-) ribozyme gene could cleave the PSTVd minus strand dimer RNA into three fragments of 77, 338, and 359 bases in vitro at 25 and 50 degrees C. The tandem dimer genes of R(-) and mR(-) were subcloned separately into the plant expression vector pROK2. Transgenic potato plants (cultivar Desirée) were generated by Agrobacterium tumefaciens-mediated transformation. Twenty-three of 34 independent transgenic plant lines expressing the active ribozyme R(-) resulted in having high levels of resistance to PSTVd, being free of PSTVd accumulation after challenge inoculation with PSTVd, but the remaining lines showed weaker levels of resistance to PSTVd with low levels of PSTVd accumulation. In contrast, 59 of 60 independent transgenic lines expressing the mutated ribozyme mR(-) were susceptible to PSTVd inoculation and had levels of PSTVd accumulation similar to that of the control plants transformed with the empty vector. The resistance against PSTVd replication was stably inherited to the vegetative progenies.

Abstract
The green fluorescent protein (GFP) gene was subcloned into the transfer vector pVLneo downstream of the polyhedrin gene (ocu) promoter. Insect cells were cotransfected with recombinant plasmid and Autographa californica Nuclear Polyhedrosis Virus (AcNPV) DNA. In the presence of G418, the recombinant virus containing GFP gene was purified. The GFP expressed in insect cells with a Mw of 30 kDa is observable by strong green light under a fluorescent microscope. Excitation and emission spectra of the GFP were 395 nm and 509 nm respectively. Integration of GFP gene on AcNPV genome was identified directly by Southern blot which gave strong hybridization signal between GFP cDNA probe and 1 kb EcoRI fragment of recombinant virus.

Abstract
12 cases of chylous ascites in PUMC hospital in the recent 30 years were analysed. The etiology of this disease includes non-traumatic (83.3%) and traumatic (16.7%) causes. All the patients received isotope examination or lymphangiography, but only in 8 patients the site of the lesion was found. As these two kinds of examination can only show the lesions in the right and left lumbar lymph trunks, cisterna chyli and throacic duct but not the intestinal lymph truck, the authors set up a method by administering orally 13C-palmitic acid to detect the lesion of intestinal lymph trunk. Palmitic acid is a long-chain fatty acid, which enters directly into the intestinal lymph trunk after absorption. Palmitic acid labelled with 13C could be detected in the ascitic fluid if there is a leak from intestinal lymph trunk. This new method was used to examine a patients who had negative results with isotope examination and lymphangiography; 13C could be detected in the ascitic fluid 30 minutes after oral administration but not in exhaled air. It can be concluded that cyhle leaked into the peritoneal cavity from the intestinal lymph trunk. This method is also of help to determine the possible site of leakage and the degree of obstruction, so it is quite useful for the diagnosis of chylous ascities.

Abstract
A hybrid-hybrid matrix method is described that quantitatively analyzes 3D NOE-NOE NMR data. Experimental 3D data are merged with simulated 3D data to create a hybrid 3D NOE-NOE spectrum. This is then deconvoluted into a 2D hybrid NOESY spectrum. The deconvoluted, 2D hybrid NOESY spectrum can then be merged with other 2D NOESY experimental data along with additional simulated 2D data as necessary to create a hybrid-hybrid 2D NOE volume matrix. This hybrid-hybrid volume matrix is then used with the complete relaxation program, MORASS, to calculate a rate matrix, and the resulting distances taken from the off-diagonal cross-relaxation rates can then be utilized in a distance geometry or restrained molecular-dynamics refinement of the structure. This process is repeated until a satisfactory agreement between the calculated and observed 3D volumes is obtained. This hybrid-hybrid matrix method retains computational efficiency and utilizes the resolution of the 3D data set while retaining any information content of the available 2D data. The initial tests of the deconvolution algorithm give high correlation results even with the introduction of random error into the 3D data set. Our results suggest that the hybrid-hybrid matrix method for analysis of 3D NOE-NOE spectra may provide a viable tool in the refinement of large molecules.

Abstract
Expression of herpes simplex virus 2 (HSV-2)-encoded ribonucleotide reductase (RR) is required for growth in nondividing cells. The functional enzyme is composed of a large and a small subunit. In virus-infected cells, RR is expressed temporally as a delayed early protein. However, the promoter regulatory region of the large subunit can function as an immediate early promoter in transient transfection assays, suggesting that expression may be quite complex. In this study, a 95-bp fragment derived from the open reading frame of the large subunit of RR (RR-A) functioned as a silencer when placed adjacent to a heterologous promoter. If the fragment was placed distal to the promoter, repression was relieved and in human keratinocytes promoter activity was consistently higher than control constructs. Exonuclease III protection assays revealed that nuclear factors from human keratinocytes as well as other primate cells specifically bind to this fragment. A 30-bp motif containing a consensus SP-1 binding site and an alternating Pu/Py element was protected in all cell lines. These results suggest that a 95-bp fragment in the open reading frame of HSV-2 RR-A plays a role in regulating viral gene expression.

Abstract
77 patients with serious resistant staphylococcal infections, including septicemia, lower respiratory infection, intraabdominal infection, skin and soft tissue infections and urinary tract infection, were treated with demethyl-vancomycin. 82% of the organisms were methicillin-resistant. Most of the patients had severe underlying diseases and were immunocompromised hosts. The infections were serious. The clinical efficacy rate was 73% and the bacteria clearance rate 68%. Mild adverse reactions happened in 11% of the patients and no obvious nephrotoxicity was noted. MIC90 of demethyl-vancomycin against staph. aureus was 2 micrograms/ml. All isolates in this study were highly susceptible to the drug. Demethyl-vancomycin was found more active against staphylococcus than the other 16 antibacterial agents, which are commonly used in this country. The indication and the use of the drug were discussed.

Abstract
Human papilloma virus type 16 (HPV-16) and herpes simplex virus type 2 (HSV-2) are human viruses implicated in the development of cancer, in particular cervical cancer. The ability of HSV-2 and HPV-16 to transform early passage human cells was examined in this report. For these studies, gingival fibroblasts were utilized. One gingival cell strain was derived from a normal individual (N-16). The second cell strain was derived from hyperplastic gingival tissue of an epileptic individual (R-30) treated with phenytoin, an antiseizure drug. A common side effect of phenytoin is the induction of gingival overgrowth. R-30 cells contained a stable chromosomal translocation between chromosomes 8 and 18 and expressed higher steady state levels of c-myc. HPV-16 DNA efficiently immortalized R-30 cells but not N-16 cells. R-30 cells cotransfected with HPV-16, and HSV-2 viral DNAs were more aneuploid than R-30 cells transfected with HPV-16 DNA alone. Additionally, R-30 cells cotransfected with both viral DNAs grew better in soft agar than R-30 cells transfected with HPV-16 DNA alone. HSV-2 DNA was detected in transformed cells by polymerase chain reaction. These results suggested R-30 cells were immortalized more efficiently by HPV-16 and further imply that HPV-16 and HSV-2 DNA fragments can cooperate during multistep transformation.

Abstract
From May to September 1989, a survey was carried out on the prevalence of cryptosporidiosis in the outpatients with diarrhea from paediatric department of five hospitals in Wuhu, Anhui Province. Cryptosporidium oocysts were identified in stool specimens from 67 of 3,498 outpatients (1.9%). No difference was found between the prevalence of cryptosporidiosis in males and that in females. No Cryptosporidium oocysts was identified in stool specimens from infants under 6-month-old. 86.2% of the cases were distributed in the age range from 7-month-old to 4-year-old. The prevalence of cryptosporidiosis in rural outpatients was two fold of that in urban outpatients. The occurrence of cases was highly sporadic. The prevalence began to rise from the last third of June. In our survey, 92.5% of the cases was distributed in the time range from the last third of June to September. In all of the cases no unique characteristic was found in clinical manifestations and stool appearance, and symptoms were resolved spontaneously. The duration of symptoms seems shorter than documented.

Abstract
Human cytomegalovirus (HCMV) transforming region II (mtrII), a 980-bp sequence, can transform rodent fibroblasts. This region contains three small potential open reading frames (ORFs) of 79, 83, and 34 amino acid residues. To identify the specific role of mtrII sequences in transformation, we investigated (1) the presence of mtrII DNA and mtrII-specific RNA transcripts in NIH 3T3 transformants and their tumor derivatives, and (2) the ability of mtrII DNA and its subregions to cis-activate chloramphenicol acetyl transferase (CAT) gene expression. By hybridization analysis, mtrII-specific DNA and RNA were detected in both transformed and tumor cells. A 285-bp sequence upstream of the ORFs in mtrII exhibited weak promoter activity when linked to CAT gene in the sense orientation with respect to the ORFs. Promoter activity of this region was stronger than the enhancer activity in the sense orientation. No promoter or enhancer activity was detected in the antisense orientation. The mtrII 980-bp sequence did not exhibit any promoter activity in either orientation. These results suggested that HCMV mtrII may contain a small transforming gene that may be transcribed at low levels from its own promoter.

Abstract
The Total alkaloid contents of chloroform extracts and aqueous decoctions of different vinegar-processed samples of fresh Rhizoma Corydalis were determined and compared using orthogonal experimental design. Two optimum schemes suggested by the results are 1. If aqueous decoction is wanted, the fresh tuber Corydalis should be scalded by hot edible vinegar till the liquid has permeated to its center; 2. If total alkaloid extract is required for making Chinese traditional patent medicine, the fresh Rhizoma should be slightly scalded with edible vinegar which has been diluted with an equal volume of water.

Abstract
Hot plate and writhing methods were used in the comparison of the analgesic effect of vinegar-processed fresh tuber corydalis and the traditionally vinegar-processed Rhizoma Corydalis. The result shows that the effect of the former is stronger than that of the latter.

Abstract
Qualitative and quantitative analysis were carried out on the samples of Rhizoma Corydalis in both the locally vinegar-processed (fresh) and traditionally vinegar-processed forms. No difference was found in the main chemical constituents. However, both the total alkaloids and the corydalis B content of the former are higher than those of the latter.
